1) The first CRISPR therapy approved in the U.S. will treat sickle cell disease:By Erin Garcia de Jesús







The gene-editing treatment aims to help people with recurring pain crises.U.S. patients with sickle cell disease now have a novel treatment option: the first-ever CRISPR-based therapy.

On December 8, the U.S. Food and Drug Administration approved the gene-editing therapy for use in patients age 12 years and older. In addition to offering hope of relief for people with severe forms of the painful blood disorder, the treatment, called Casgevy, is the world’s first to genetically tweak cells using the Nobel Prize–winning molecular scissors CRISPR/Cas9 (SN: 10/7/20).Another gene therapy for sickle cell disease, called Lyfgenia and developed by biotech company bluebird bio, based in Somerville, Mass., was also approved December 8.

Getting a green light for the first CRISPR-based medicine is exciting, says David Altshuler, chief scientific officer at Boston-based Vertex Pharmaceuticals, which developed the drug in a joint venture with CRISPR Therapeutics, a company in Cambridge, Mass. But the fact that the drug fills an unmet need for underserved patients is “more compelling to me, personally, than the fact that it’s CRISPR.”

Approximately 100,000 people in the United States, most of them Black or Latino, have sickle  cell disease. It is caused by a genetic defect in hemoglobin, the oxygen-carrying protein in red blood cells. Unlike typical blood cells that are bendy enough to slip through blood vessels, sickled blood cells are inflexible and get stuck, restricting blood flow and causing debilitating pain (SN: 2/1/22). People with severe forms of the disease can be hospitalized multiple times a year. 

Having a new treatment option for sickle cell disease can give patients a “new lease on life,” says Kerry Morrone, a pediatric hematologist at Albert Einstein College of Medicine in New York City. People with the disease often miss school, work or special events due to excruciating pain. “The potential that this therapy could alleviate symptoms for patients is very exciting.”

At an FDA advisory committee meeting on October 31, several clinical trial participants given Casgevy recounted how it changed their lives, including Victoria Gray, the first sickle cell patient to enroll in the trial.Gray has previously described bouts of pain that felt like being struck by lightning and getting hit by a train at the same time (SN: 10/20/23). Now pain-free, she is able to enjoy time with her family, Gray said at the meeting.

Jimi Olaghere, another participant in the trial, told a similar tale. Before the treatment, “sickle cell disease dominated every facet of my life,” he said. “Hospital admissions were so regular that they even had a bed reserved for me.” Now, Olaghere is free of pain and able to be present for his children. “Gene therapy has given me the ability to take full control of my life,” he said. “I can chase to the proverbial sunset and write novels and even dance in the rain without a care in the world.”    

There are few existing therapies for sickle cell disease, which include taking drugs like hydroxyurea or undergoing bone marrow transplants (SN: 12/17/20). But hydroxyurea doesn’t work for everyone, and transplants require a genetically matched donor, usually a sibling. Less than 20 percent of people with sickle cell disease have a matched sibling.

Casgevy is like a transplant, but instead relies on a patient’s own cells. Using CRISPR, the treatment alters the genetic blueprint of bone marrow cells that give rise to blood cells. The edited cells make fetal hemoglobin, a type normally made by fetuses and young babies that doesn’t make red blood cells sickle and gum up vessels (SN: 8/14/19).

Patients first receive chemotherapy to wipe out existing bone marrow cells so the new ones, which are edited in a lab, have a chance to thrive in the body. After editing, the cells are given back to the patient through an IV. Both steps require hospitalization. 

In a clinical trial, 29 out of 30 patients given Casgevy and followed for at least 16 months didn’t have pain crises for at least a year, Vertex vice president of clinical development William Hobbs said at the FDA advisory committee meeting. 

The treatment isn’t without risks. Chemotherapy, for instance, can raise the risk of blood cancer and cause infertility. And in the short-term, chemotherapy kills immune cells, putting patients at higher risk dying from infections.

For some patients those risks may pale in comparison to the prospect of a year without immense pain, says Morrone, who is also director of the Sickle Cell Program at the Children’s Hospital at Montefiore. Others may want to wait and see what the outcomes are. “I think that’s fair, because it’s not without any risk.”

At the Oct. 31 meeting, advisors to the FDA also discussed the potential for unintended edits, or “off-target effects.” An analysis by Vertex found no evidence of such unwanted changes in treated patients, although researchers have identified a rare variation in the DNA of some people that could, in theory, be an accidental target. 

It’s unknown whether changing that accidental target would have consequences for patients, but researchers say it’s unlikely because that stretch of DNA isn’t involved in a protein’s structure or function. Nor is the protein made from that genetic code found in blood cells. Overall, the 14-member committee agreed that the benefits of the treatment were clear and the off-target risk is small, but that additional research would be helpful.

Another concern is that the therapy is expensive, perhaps as much as $2 million per patient. But health care costs for sickle cell patients are also high over their lifetime, Morrone says. The health care community needs to consider ways to ensure equity for patients — including in Africa, where the highest burden of disease is — who have long not had the same resources as patients with other conditions with far more treatment options. “There’s not a value on suffering,” she says. 

On November 16, officials in the United Kingdom became the first to sign off on Casgevy’s use in sickle cell patients as well as people with beta-thalassemia, a blood disorder in which the body doesn’t make enough hemoglobin. The FDA will decide by March 30 whether the CRISPR therapy can also be used to treat beta-thalassemia by March 30.

“Sickle cell disease is a chronic, debilitating condition,” says Dr. Monica Bhatia, a pediatric hematologist-oncologist and director of the Pediatric Stem Cell Transplant Program at NewYork-Presbyterian Morgan Stanley Children’s Hospital. “Today’s approvals mean that many more patients will have an option to treat pain episodes and other symptoms of this disease.” Dr. Bhatia led the Columbia team that treated adolescent sickle cell patients with Casgevy during its multi-center clinical trials.

2) A maverick physicist is building a case for scrapping quantum gravity:By Emily Conover








A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of physicists have spent their careers working to build a theory of quantum gravity.But one physicist is championing a radically different path. Jonathan Oppenheim thinks that gravity might be fundamentally classical, meaning it isn’t quantum at all. It’s an unconventional idea, to say the least.When we started, maybe 99 percent of our colleagues thought we were crackpots and that’s now down to maybe 70 percent,” quips Oppenheim, of University College London.

All known forces except gravity are formulated in terms of quantum physics. The prevailing view is that gravity will need to assimilate with its quantum colleagues. But gravity is different, Oppenheim argues. While other forces evolve within a landscape of spacetime, gravity is the warping of spacetime itself. So, Oppenheim says, “it is pretty unclear that it should have a quantum nature, in my view.”

Physicists have devised several “no-go” theorems that seemingly forbid a classical theory of gravity. Such theorems highlight inconsistencies, apparently fatal to the idea, that arise when classical gravity is applied to quantum particles. But it’s possible to get around those prohibitions by adding some randomness to the way that spacetime bends in response to quantum particles, Oppenheim reports December 4 in Physical Review X.

Consider the famous double-slit experiment of quantum physics (SN: 5/3/19). Particles are sent toward a detector, separated by a barrier with two slits in it. When those particles arrive at the detector, they create a stripy pattern called an interference pattern. That pattern arises because, in quantum physics, the particle isn’t constrained to pass through one slit or the other. Instead, it can exist in a superposition, taking a quantum combination of both possible routes. If a scientist makes a measurement to determine which slit the particle passed through, that pattern disappears. If a standard classical picture of gravity were correct, it would be possible to measure the gravitational field of that particle so precisely that you could determine which slit the particle went through. This possibility would destroy the interference pattern, even without actually doing the measurement. Because scientists do observe interference patterns in the lab, that’s a big blow for a standard classical theory of gravity.

But the randomness baked into Oppenheim’s theory means that, instead of a particle having a determined gravitational field, the field fluctuates. That means, unlike for the standard version of classical gravity, it’s not possible to determine which slit a particle went through by precisely measuring its gravitational field. Particles can pass through the slits in a superposition, and the interference pattern is saved, restoring the possibility gravity could be classical.

Experiments can test this theory by searching for evidence of those random gravitational fluctuations, Oppenheim and colleagues report December 4 in Nature Communications. “Essentially, you very precisely measure the response of a mass to a gravitational field,” says study coauthor Zach Weller-Davies, who completed the work at the Perimeter Institute for Theoretical Physics in Waterloo, Canada.

This is not the first time scientists have proposed a way to make classical gravity comport with quantum physics. But Oppenheim has been “leading a renaissance,” says physicist Vivishek Sudhir of MIT. Sudhir hopes to test the theory with another type of experiment, measuring the correlations between the motions of two masses that interact gravitationally, he and a colleague report September 16 at arXiv.org.However, the theory has features some physicists might find unsatisfying. For example, the randomness involved means that the theory is not reversible: Unlike other theories, there’s no way to start from the endpoint of an interaction and trace its steps backward.

Still, even some quantum gravity believers think that the work has merit.

“The reason why this work is interesting for me is not really because I would believe that gravity is classical,” says Flaminia Giacomini of ETH Zurich. The result, she says, is interesting regardless of whether gravity is found to be classical or quantum. That’s because, in order for an experiment to confidently proclaim that gravity is quantum, scientists need to understand the possibilities for classical gravity. “Only in that way will we be able to prove in a strong way that gravity is not compatible with a classical description.”

3) New enzyme allows CRISPR technologies to accurately target almost all human genes :by Michaela Kane, Duke University

Credit Nature Chemical Biology (2023)NEWCRISPERENZ


A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentially target and treat a broader range of diseases through genome engineering.The research involved collaborators at Harvard University, Massachusetts Institute of Technology, University of Massachusetts Medical School, University of Zurich and McMaster University.

This work was published on October 4 in the journal Nature Communications.

CRISPR-Cas is a bacterial immune system that allows bacteria to use RNA molecules and CRISPR-associated (Cas) proteins to target and destroy the DNA of invading viruses. Since its discovery, researchers have raced to develop an arsenal of new CRISPR systems for applications in gene therapy and genome engineering.

To make edits to the genome, Cas proteins utilize both an RNA molecule, which guides the enzyme to a targeted stretch of DNA, and a protospacer adjacent motif, or PAM, which is a short DNA sequence that immediately follows the targeted DNA sequence and is required for the Cas protein to bind.

Once a guide RNA finds its complementary DNA sequence and the Cas enzyme binds the adjacent PAM, the enzyme acts like scissors to make a cut in the DNA, triggering the desired changes to the genome. The most common CRISPR-Cas system is the Cas9 from Streptococcus pyogenes bacteria (SpCas9), which requires a PAM sequence of two guanine bases (GG) in a row.

In previous work, Chatterjee and his team used bioinformatics tools to discover and engineer new Cas9 proteins, including Sc++, which only requires a single guanine base PAM to make a cut. This change made it possible for researchers to edit nearly 50% of all DNA sequences.At the same time, Chatterjee's collaborators at Harvard, led by Benjamin Kleinstiver, an assistant professor at Harvard Medical School, engineered a separate variant called SpRY. While SpRY could bind to any one of the four DNA bases that could form the PAM, it had a much stronger affinity for adenine and guanine.Because both systems had drawbacks, the group decided to put the best of both together into a new variant called SpRyc."CRISPR is a great tool for editing specific DNA, but we're still restricted on which genes we can edit. The original CRISPR tool could only edit about 12.5% of all DNA sequences based on where that specific spacer was located. If you happen to have a mutation in the other 87.5%, you'd be out of luck. With this new tool, we can target nearly 100% of the genome with far more precision," said Chatterjee.While SpRYc was slower than its counterparts at cutting target DNA sequences, it was more effective than both the traditional enzymes at editing specific sections of DNA. Despite SpRYc's broadness, it was also more accurate than SpRY.After establishing SpRYc's editing capabilities, the team investigated the tool's potential therapeutic uses for genetic diseases that were untreatable with the standard CRISPR system. Their first test was Rett syndrome, a progressive neurological disorder that predominantly affects young females and is caused by one of eight mutations to a specific gene.The second was Huntington's disease, a rare, inherited neurological disorder that causes the degeneration of neurons in the brain. The team found that SpRYc was able to alter previously inaccessible mutations, providing potential therapeutic opportunities for both diseases."There is a lot of potential with SpRYc, whether it's exploring how to translate it into the clinic or finding ways to make it even more efficient," said Chatterjee. "We look forward to exploring the full capabilities of our tool."

4) Researchers crack the cellular code on protein folding, offering hope for many new therapeutic avenues :by University of Massachusetts Amherst





While we often think of diseases as caused by foreign bodies—bacteria or viruses—there are hundreds of diseases affecting humans that result from errors in cellular production of proteins.A team of researchers led by the University of Massachusetts Amherst leveraged the power of cutting-edge technology, including an innovative technique called glycoproteomics, to unlock the carbohydrate-based code that governs how certain classes of proteins form themselves into the complex shapes necessary to keep us healthy.

The research, published in the journal Molecular Cell, explores members of a family of proteins called serpins, which are implicated in a number of diseases. The research is the first to investigate how the location and composition of carbohydrates attached to the serpins ensure that they fold correctly.

protein-folding

Serious diseases—ranging from emphysema and cystic fibrosis to Alzheimer's disease—can result when the cellular oversight of protein folding goes awry. Identifying the glyco-code responsible for high-fidelity folding and quality control could be a promising way for drug therapies to target many diseases.Scientists once thought that the single code governing life was DNA, and that everything was governed by how DNA's four building blocks—A, C, G and T—combined and recombined. But in recent decades, it has become clear that there are other codes at work, and especially in building the intricately folded, secreted proteins that are created in the human cell's protein factory, the endoplasmic reticulum (ER), a membrane-enclosed compartment where protein folding begins.

Approximately 7,000 different proteins—one-third of all the proteins in the human body—mature in the ER. The secreted proteins—collectively known as the "secretome"—are responsible for everything from our body's enzymes to its immune and digestive systems and must be formed correctly for the human body to function normally.Special molecules called "chaperones," help fold the protein into its final shape. They also help to identify proteins that haven't folded quite correctly, lending them additional help in refolding, or, if they're hopelessly misfolded, targeting them for destruction before they cause damage. However, the chaperone system itself, which comprises a part of the cell's quality control department, sometimes fails, and when it does, the results can be catastrophic for our health.The discovery of the carbohydrate-based chaperone system in the ER was due to the pioneering work that Daniel Hebert, professor of biochemistry and molecular biology at UMass Amherst and one of the paper's senior authors, initiated as a postdoctoral fellow in the 1990s."The tools we have now, including glycoproteomics and mass spectrometry at UMass Amherst's Institute for Applied Life Sciences, are allowing us to answer questions that have remained open for over 25 years," says Hebert. "The lead author of this new paper, Kevin Guay, is doing things I could only dream of when I first started."Among the most pressing of these unanswered questions is: how do chaperones know when 7,000 different origami-like proteins are correctly folded?We know now that the answer involves an "ER gatekeeper" enzyme known as UGGT, and a host of carbohydrate tags, called N-glycans, which are linked to specific sites in the protein's amino acid sequence.

Guay, who is completing his Ph.D. in the molecular cellular biology program at UMass Amherst, focused on two specific mammalian proteins, known as alpha-1 antitrypsin and antithrombin.

Using CRISPR-edited cells, he and his co-authors modified the ER chaperone network to determine how the presence and location of N-glycans affected protein folding.They watched as the disease variants were recognized by the ER gatekeeper UGGT and, in order to peer more closely, developed a number of innovative glycoproteomics techniques using mass spectrometry to understand what happens to the glycans that stud the surface of the proteins.What they discovered is that the enzyme UGGT "tags" misfolded proteins with sugars placed in specific positions. It's a sort of code that the chaperones can then read to determine exactly where the folding process went wrong and how to fix it.

"This is the first time that we've been able to see where UGGT puts sugars on proteins made in human cells for quality control," says Guay. "We now have a platform for extending our understanding of how sugar tags can send proteins for further quality control steps and our work suggests that UGGT is a promising avenue for targeted drug therapy research.""What's so exciting about this research," says Lila Gierasch, distinguished professor of biochemistry and molecular biology at UMass Amherst and one of the paper's co-authors, "is the discovery that glycans act as a code for protein folding in the ER. The discovery of the role that UGGT plays opens the door to future advancement in understanding and eventually treating the hundreds of diseases that result from misfolded proteins."

5) Study reveals genes that set humans apart from other primates in cognitive ability :by Anika Hazra, University of Toronto







An international team led by researchers at the University of Toronto has uncovered over 100 genes that are common to primate brains but have undergone evolutionary divergence only in humans—and which could be a source of our unique cognitive ability.

The researchers, led by Associate Professor Jesse Gillis from the Donnelly Center for Cellular and Biomolecular Research and the department of physiology at U of T's Temerty Faculty of Medicine, found the genes are expressed differently in the brains of humans compared to four of our relatives—chimpanzees, gorillas, macaques and marmosets.

The findings, published in Nature Ecology & Evolution, suggest that reduced selective pressure, or tolerance to loss-of-function mutations, may have allowed the genes to take on higher-level cognitive capacity. The study is part of the Human Cell Atlas, a global initiative to map all human cells to better understand health and disease.

"This research contributes to our understanding of differences in the brain between humans and other primates at the cellular level, but it has also resulted in a database that can be used to further characterize genetic similarities and differences across primates," said Gillis.

The team, which includes researchers from Cold Spring Harbor Laboratory and the Allen Institute for Brain Science in the U.S, created a brain map for each primate species based on single-cell analysis, a relatively new technique that enables more specific genetic sequencing than standard methods. They used a BRAIN Initiative Cell Census Network (BICCN) dataset created from samples taken from the middle temporal gyrus of the brain.

In all, the team found 139 genes that are common across the primate groups but highly divergent in their expression in human brains. These genes displayed a stronger ability to withstand mutations without impacting their function, suggesting they may have evolved under more relaxed selective pressure.

"The genes that have diverged in humans must be tolerant to change," said Hamsini Suresh, first author on the study and a research associate at the Donnelly Center. "This manifests as tolerance to loss-of-function mutations, and seems to allow for rapid evolutionary change in the human brain."

Our higher cognitive function may have resulted from the adaptive evolution of human brain cells to a multitude of less threatening mutations over time. It's also worth noting that around a quarter of the human-divergent genes identified in the study are associated with various brain disorders.The divergent genes the researchers identified are found in 57 brain cell types, grouped by inhibitory neurons, excitatory neurons and non-neurons. A quarter of the genes were only expressed differently in neuronal cells, also known as gray matter, and half were only expressed differently in glial cells, which are white matter.

Gray matter in the brain consists of neurons, while white matter consists of other cell types, including those responsible for vasculature and immune function.

This study is part of the BICCN initiative to identify and catalogue the diverse cell types in the brains of humans and other species. In 2021, the consortium published a comprehensive census of cell types in the mouse, monkey and human primary motor cortex in the journal Nature. The initiative is shedding light on the evolution of the brain by studying neurotransmission and communication at the finest resolution.

"There are around 570,000 cells in the cross-primate single cell atlas of the middle temporal gyrus," said Suresh. "Defining a catalogue of shared cell types in this area of the brain provides a framework for exploring the conservation and divergence of cellular architecture across primate evolution. We can use the resulting information to study evolution and disease in a more targeted manner."

6) New genes found that can arise 'from nothing':by University of Helsinki

Researchers studied an error mechanism in DNA replication, and noticed that some errors create palindromes that can fold into hairpin structures






The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers at the University of Helsinki resolved outstanding questions around the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes The human genome contains ca. 20,000 genes that are used for the construction of proteins. Actions of these classical genes are coordinated by thousands of regulatory genes, the smallest of which encode microRNA molecules that are 22 base pairs in length. While the number of genes remains relatively constant, occasionally, new genes emerge during evolution. Similar to the genesis of biological life, the origin of new genes has continued to fascinate scientists.

All RNA molecules require palindromic runs of bases that lock the molecule into its functional conformation. Importantly, the chances of random base mutations gradually forming such palindromic runs are extremely small, even for the simple microRNA genes.

Hence, the origin of these palindromic sequences has puzzled researchers. Experts at the Institute of Biotechnology, University of Helsinki, Finland, resolved this mystery, describing a mechanism that can instantaneously generate complete DNA palindromes and thus create new microRNA genes from previously noncoding DNA sequences.

In their project, the researchers studied errors in DNA replication. Ari Löytynoja, the project leader, compares DNA replication to typing of text.

"DNA is copied one base at a time, and typically mutations are erroneous single bases, like mis-punches on a laptop keyboard. We studied a mechanism creating larger errors, like copy-pasting text from another context. We were especially interested in cases that copied the text backward so that it creates a palindrome."

Researchers recognized that DNA replication errors could sometimes be beneficial. They described these findings to Mikko Frilander, an expert in RNA biology. He immediately saw the connection to the structure of RNA molecules.

"In an RNA molecule, the bases of adjacent palindromes can pair and form structures resembling a hairpin. Such structures are crucial for the function of the RNA molecules," he explains.Researchers decided to focus on microRNA genes due to their simple structure: the genes are very short—just a few tens of bases—and they have to fold into a hairpin structure to function correctly.A central insight was to model the gene history using a custom computer algorithm. According to postdoctoral researcher Heli Mönttinen, this enables the closest inspection of the origin of genes thus far."The whole genome of tens of primates and mammals is known. A comparison of their genomes reveals which species have the microRNA palindrome pair and which lack it. With a detailed modeling of the history, we could see that whole palindromes are created by single mutation events," says Mönttinen.By focusing on humans and other primates, researchers in Helsinki demonstrated that the newly found mechanism can explain at least a quarter of the novel microRNA genes. As similar cases were found in other evolutionary lineages, the origin mechanism appears universal.In principle, the rise of microRNA genes is so easy that novel genes could affect human health. Heli Mönttinen sees the significance of the work more broadly, for example, in understanding the basic principles of biological life.

"The emergence of new genes from nothing has fascinated researchers. We now have an elegant model for the evolution of RNA genes," she highlights.

Although the results are based on small regulatory genes, researchers believe that the findings can be generalized to other RNA genes and molecules. For example, by using the raw materials generated by the newly found mechanism, natural selection may create much more complex RNA structures and functions.

7) Study reshapes understanding of mass extinction in Late Devonian era :by Indiana University

Diverse and full of sea life, the Earth's Devonian era—taking place more than 370 million years ago—saw the emergence of the first seed-bearing plants, which spread as large forests across the continents of Gondwana and Laurussia.However, a mass extinction event near the end of this era has long been the subject of debate. Some scientists argue the Late Devonian mass extinction was caused by large-scale volcanic eruptions, causing global cooling. Others argue a mass deoxygenation event caused by the expansion of land plants was to blame.

A recently published study in the journal Communications Earth & Environment led by researchers at IUPUI now posits that both factors played a role—and draws attention to the environmental tipping points the planet faces today.The study is co-authored by School of Science at IUPUI faculty Gabriel Filippelli and William Gilhooly III. The lead author is Matthew Smart, an assistant professor of oceanography at the U.S. Naval Academy who was a graduate student in Filippelli's lab at the time of the study.

The work is the first to unify two competing Late Devonian extinction theories into a comprehensive cause-and-effect scenario. Essentially, the group concluded that both events—mass volcanism and deoxygenation caused by land plants flushing excess nutrients into oceans—needed to occur for the mass extinction to take place.

"The key to resolving this puzzle was identifying and integrating the timing and magnitude of the geochemical signals we determined using a sophisticated global model," Filippelli said. "This modeling effort revealed that the magnitude of nutrient events we were seeing based on the geochemical records could drive substantial marine extinction events, but the duration of the events required both factors—tree root evolution and volcanism—to sustain the marine conditions that were toxic to organisms."

With experts in sedimentology, paleontology, geochemistry, biogeochemistry and mathematical modeling, the group literally dug deep to geochemically analyze hundreds of samples scattered across different continents. These include samples from Ymer Island in eastern Greenland, home of some of the oldest rock samples on the planet.

"The process was highly interdisciplinary," Gilhooly said. "This combined expertise created a rigorous approach to collecting the samples, correlating sequences in time, acquiring the chemical data and using geochemical models to test working hypotheses about the relative influences of biotically—plants—and chemically—volcanoes—driven triggers of mass extinction. Our analyses demonstrate that the influences are much more mixed than an either-or scenario."

Filippelli and Gilhooly said the study's conclusion gives researchers a lot to consider. During the Devonian era, new biological outcomes on land produced negative effects for life in the ocean. In the present day, Gilhooly noted, activity like fertilizer runoff emptying into the ocean, combined with heating from fossil fuel combustion, are reducing oceans' oxygen levels. The previous outcome of this similar scenario in the Late Devonian had catastrophic outcomes, he said.

"Throughout Earth's history, there have been a series of biological innovations and geological events that have completely reshaped biological diversity and environmental conditions in the ocean and on land," Gilhooly said.

"In the Devonian era, a new biological strategy on land produced a negative impact for life in the ocean. This is a sobering observation when put in the context of modern global and climatic change driven by human activities. We have a lot to learn from Earth history that can help us think of strategies and actions to avoid future tipping points."



1) Amid Congress' lead in Telangana, party leader says 'It's a fair reward’; hints BRS leaders are ‘in touch’:



Congress leader said today's politics is in line with nicking off leaders from opposition parties. “Sometimes they take away ours, sometimes theirs come here”.As Congress shows a comfortable lead in at least 60 seats out of the 199-member Telangana assembly, party leader Renuka Chowdhury mulled “it is a fair reward” for the grand old party as they have been “praying” for a victory in the state for the last 10 years.

The Congress leader further said leaders of the ruling Bharat Rashtra Samithi (BRS) “are in touch with us”, adding that “today's politics is like that”. "Sometimes they take away ours (MLAs), and sometimes theirs come here," she said.As per the latest trends, Congress has crossed the halfway mark at 63 seats, whereas BRS is trailing with 43. BJP managed to bag 9 seats and others including CPI on 4.

"I had been saying for more than a year because we tapped into the pulse of the public. We understood that a big change is going to come and that is what is happening. Victory is ours, I am very confident. People were tired of BRS. BJP and BRS are one - everyone understood it. They also understand the dangerous role that AIMIM played. I think AIMIM, Owaisi has suffered the biggest loss in this game. People understood the truth behind the wrong step he took at the national level. It is unfortunate because I had always considered him to be an intelligent man. When Congress contests unitedly, no force in the country can stand against us," she said.

2) India’s BJP wins three of four state polls months before national election



The Hindu nationalist party wrests control of Chhattisgarh and Rajasthan from the Congress and wins record fifth term in Madhya Pradesh.India’s ruling Hindu nationalist party has won three out of four key state elections, according to the election commission’s website.

The crucial polls pitted India’s opposition against the ruling Bharatiya Janata Party (BJP) of Prime Minister Narendra Modi ahead of the vital national vote, scheduled in less than six months.Ballot counting on Sunday showed the BJP wrested control of the heartland states of Chhattisgarh and Rajasthan from the Indian National Congress, India’s main opposition party.

Of 90 assembly constituencies in Chhattisgarh, the BJP bagged 54 while the Congress won 35. In Rajasthan, the BJP got 115 of 199 seats.

The right-wing party was also likely to be re-elected in Madhya Pradesh for a record fifth term by winning 163 of 230 seats.The Congress comfortably won Telangana state, which was ruled by the Bharat Rashtra Samithi party, formerly known as the Telangana Rashtra Samithi. Of 119 seats in the southern state, the Congress won 64, while the BRS got 39. The BJP won an impressive eight seats in the state.Vote counting in a fifth state, Mizoram, is set for Monday where BJP’s regional ally, the Mizo National Front, is in power.Elections in the five states were held last month and more than 160 million people, or a sixth of India’s electorate, were eligible to vote. Polling in India is generally done in phases owing to the large population.

Historic and unprecedented’

The election results indicate the voter mood ahead of the national elections in May in which Modi is eyeing a third consecutive term.

At the BJP headquarters in New Delhi on Sunday evening, party members and supporters lined up on the two sides and Modi walked between them, waving. The activists showered him with flower petals, chanting “Long live Mother India” and other slogans.Later, Modi in a speech said the results were “historic and unprecedented” and “a victory for honesty, transparency and good governance”.

“The results in Chhattisgarh, Madhya Pradesh and Rajasthan indicate that the people of India are firmly with politics of good governance and development, which the @BJP4India stands for,” Modi wrote on X, formerly known as Twitter.

New opposition alliance

Modi and his BJP remain popular on a national level after nearly a decade in power and surveys suggest he is expected to win a third term.However, a new alliance of 28 opposition parties, called the Indian National Developmental Inclusive Alliance or INDIA, is set to challenge the BJP nationally. It is led by the the Congress.

Rahul Gandhi, the Congress leader, conceded defeat in the three states where his party was trailing.

“The battle of ideology will continue,” he wrote on X, and thanked the people of Telangana where his party was winning.The charged-up voting campaigns witnessed both leaders promising voters subsidies, loan waivers and employment guarantees.

The elections came at a time when India is facing multiple challenges – rising unemployment, attacks and “hate speech” by Hindu nationalists against the country’s minorities, particularly Muslims, and a shrinking space for dissent and free media.Although Congress won Telangana, its second victory in the south this year, Sunday’s outcome was seen as a setback to the party and its leader, Gandhi, as it was wiped out of the politically critical heartland.

“We always said we will win the heartland states,” BJP president Jagat Prakash Nadda said. “The results are the outcome of our finest political strategy and work on the ground.”

4) How is it possible?’: Kamal Nath claims ex-MLAs didn't even get 50 votes in assembly polls



Kamal Nath's claim was in line with Digvijaya Singh's earlier remark on possible tampering with electronic voting machines (EVM).Senior Congress leader Kamal Nath on Tuesday expressed his surprise over the results of the Madhya Pradesh assembly election after he claimed that some former MLAs complained to him that they got not more than 50 votes in their seats. His claim resonates with his party colleague and Congress veteran Digvijaya Singh's remark on possible electoral malpractices during this election.

"We are holding discussions with the elected and non-elected MLAs and analysing the result. Some MLAs have met me, and one of them told me that he got only 50 votes in his own village. How is this possible?...Exit polls are done only to create an atmosphere," Kamal Nath told reporters earlier.Kamal Nath's claim was in line with Digvijaya Singh's earlier remark on possible tampering with electronic voting machines (EVM). “Any machine with a chip can be hacked,” Singh wrote on X (formerly Twitter).

BJP and Congress among other Opposition parties are at loggerheads over the election result following Singh's remark which was also backed by leaders from the parties including National Conference and Shiv Sena (UBT).

“The poll results are unexpected and surprising but we respect the democratic process. When the mandate goes against your party, one has to accept it. However, the results of Madhya Pradesh are not only surprising but also shocking for us. The poll results in three of four states should be considered as the EVM mandate and it has to be accepted in that way only,” Shiv Sena (UBT) Sanjay Raut said earlier.

However, while asked if EVM was hacked, Kamal Nath said, “It would not be right to conclude without holding discussions. I will talk to everyone first,” while expressing surprise at the poll results. "Even you know what the mood was. Why are you asking me? Ask the people," he added.

The BJP won 163 seats in the 230-member assembly, pushing the Congress far behind with 66 seats.Meanwhile, speculations of Kamal Nath's resignation as state Congress chief were rife following the party's defeat. He is likely to meet party president Mallikarjun Kharge on Tuesday and may tender his resignation from the post, as per sources cited by PTI.

4) Mahua Moitra expelled from Lok Sabha: What next for TMC leader? Options before her



Mahua Moitra expelled: Former Lok Sabha secretary general PDT Achary said Mahua Moitra has the option of challenging the expulsion in the Supreme Court.Mahua Moitra of the Trinamool Congress was expelled on Friday from the Lok Sabha after the House adopted the report of its ethics committee that found her guilty of accepting gifts and illegal gratification from businessman Darshan Hiranandani to further his interest.

The committee report found Moitra guilty of "unethical conduct" and contempt of the House by sharing her Lok Sabha credentials – user ID and password of Lok Sabha Member's Portal, with unauthorised persons which had an irrepressible impact on national security, Joshi said.“The serious misdemeanours on the part of Smt Mahua Moitra calls for severe punishment. The Committee, therefore, recommend that Smt Mahua Moitra, MP may be expelled from the membership of the 17th Lok Sabha. In view of highly objectionable, unethical, heinous and criminal conduct of Smt. Mahua Moitra, the Committee recommend for an intense, legal, institutional inquiry by the Government of India in a time-bound manner,” the panel report said.It said that a “threadbare examination” had established, beyond doubt, that Moitra had “deliberately” shared her Lok Sabha login credentials with businessman Darshan Hiranandani. “Therefore, Smt Mahua Moitra is guilty of unethical conduct, breach of her privileges available to members of Parliament and contempt of the House.”

Former Lok Sabha secretary general PDT Achary said Moitra has the option of challenging the expulsion in the Supreme Court. “Normally, House proceedings cannot be challenged on the ground of procedural irregularity. Article 122 of the Constitution is clear. It gives immunity to the proceedings from a challenge from court,” Achary told The Indian Express.According to Article 122, “the validity of any proceedings in Parliament shall not be called (into) question on the ground of any alleged irregularity of procedure”. It states that “no officer or Member of Parliament in whom powers are vested by or under this Constitution for regulating procedure or the conduct of business, or for maintaining order, in Parliament shall be subject to the jurisdiction of any court in respect of the exercise by him of those powers”.Achary, however, said the Supreme Court said in the 2007 Raja Ram Pal case that “those restrictions are only for procedural irregularities. There may be other cases where judicial review may be necessary.”

India Today reported that Moitra can file an appeal against the committee's decision in the Supreme Court or the high court based on the grounds of natural justice and principles of fair hearing.

Moitra could also challenge the jurisdiction and conduct of the ethics committee, it reported. She could argue that the panel overstepped its mandate, that the proceedings were irregular.

The expelled TMC MP could also approach senior Parliament or government officials through her party or independent avenues, alleging bias, prejudice or any sort of malfeasance in the committee's proceedings, India Today added.The motion moved by Joshi said that Moitra’s "conduct has further been found to be unbecoming as a member of parliament for accepting gifts and illegal gratification from a businessman to further his interest which is a serious misdemeanour and highly deplorable conduct" on her part.

Om Birla cites 2005 case

Parliamentary affairs minister Pralhad Joshi moved a motion to expel Moitra for "unethical conduct", which was adopted by a voice vote.

Joshi urged the House to accept the recommendation and finding of the panel and "resolve that continuance of Mahua Moitra as member of Lok Sabha is untenable and she may be expelled from the membership of the Lok Sabha".

Trinamool Congress and other opposition members demanded that Moitra be allowed to put her views in the House, which was turned down by Speaker Om Birla citing past precedence.Birla observed that in 2005, the then Speaker Somnath Chatterjee had in a directive disallowed 10 Lok Sabha members, who were involved in a 'cash for questions' scam, to speak in the House.

Joshi said in 2005 the then Leader of the House Pranab Mukherjee had moved a motion to expel 10 members on the same day the report was introduced in the Lok Sabha

Earlier, ethics committee chairman Vinod Kumar Sonkar tabled the first report of the Committee on the complaint filed by BJP member Nishikant Dubey against Moitra.

5) The ballot revolution led by women voters:



The emergence of the woman voter has meant that there are new deals to be made between parties and potential voters Let’s count what we do know. The first is that more women are voting, in some cases in larger numbers than men. There is evidence also that women are exercising their ballot independently, unmindful of family consideration or which way their husbands instruct them to vote. The second fact. Despite the near unanimous passage of the Nari Shakti Vandan Adhiniyam bill that will set aside 33% of seats in Parliament and the state assemblies for women, political parties without exception remain plagued by an old problem: A reluctance to share power with women. These elections have been no different. Analysis by this newspaper finds that women accounted for less than 12% of the candidates fielded by the two major national parties, the BJP and the Congress in Madhya Pradesh, Rajasthan, Chhattisgarh, Telangana, and Mizoram.

For 200 seats in the Rajasthan assembly, the BJP fielded just 20 women and the Congress 28. Women comprise a paltry 10% of the new assembly. In Barmer, Priyanka Chowdhary, a BJP rebel stood as an independent and won. “Male politicians don’t want women to succeed or come forward,” she told The Indian Express. “They find a dedicated, hard-working and strong woman politician a threat.” The Congress loss in the state is being attributed at least partly to rising crime against women with more women voting for the BJP than the Congress.

Yet, because the data tell us that more women are voting independently than ever before, political parties can no longer ignore the woman voter, and this is the third fact. From free bus fares to subsidised LPG cylinders, from cash handouts to fixed deposits, parties, otherwise so stingy about fielding women candidates, are extremely generous when it comes to these sort of promises.

Four-time incumbent chief minister Shivraj Singh Chouhan’s stunning victory in Madhya Pradesh is being put down to his women-oriented schemes including the Ladli Behna and Ladli Lakshmi yojana that makes direct cash transfers to woman. The Axis My India exit poll found a gender gap of 10 percentage points with more women backing the BJP, writes senior fellow at the Centre for Policy Research, Neelanjan Sircar in this paper. But analysis by Lokniti-CSDS finds that women’s turnout surpassed that of men in only 34 of 230 assembly constituencies and that more men than women voted for the BJP.

In Telangana, with 1.63 crore women voters compared to 1.62 crore men, the Congress repeated some of the promises it had made in the run up to its Karnataka victory. These included free bus travel for women, subsidised LPG cylinders and monthly financial assistance to poor women. The Bharat Rashtra Samithi promised a higher amount and shaved off another ₹100 from the subsidized LPG cylinders, yet lost.

In Chhattisgarh, the Congress lost despite its promise of ₹15,000 a year to unmarried women being more than the BJP’s promise of ₹12,000. The bright spot is of course Mizoram that has elected three women—the most ever—in a region that has traditionally opposed the participation of women in politics.

Women can swing elections, which is why every party now offers sops. But since nobody knows quite what works, the results are varied. What works in one state, won’t in another. What works for one election, doesn’t become the template for all. The simple truth is there is no formula. Nor is there a monolithic “woman vote”. Women vote not just as women but as minorities, as Dalits, as farmers, as housewives. And this is the fourth evident fact. Nobody knows what women want.

But this much is clear. Voters in India have proved to be extremely canny and women voters are able to spot genuine commitment. In the end, there are no short cuts and it cannot be a coincidence that among metro cities, Kolkata with Mamata Banerjee as West Bengal chief minister records the lowest crime against women.

The assiduous cultivation of women’s self-help groups (SHG) has led to the growth of powerful collectives. Bihar’s longest-serving chief minister, Nitish Kumar has found not just a loyal vote bank. He’s returned the favour by keeping his promise of state-wide prohibition made to SHGs. His track record in fielding women candidates is as bad as any other party, but his government was the first to give free cycles to middle school girls so that they remain in school.“Parties think of voters through a very transactional lens,” says Akshi Chawla, curator of #WomenLead, a platform that tracks the political representation of women globally. The emergence of the woman voter has meant that there are new deals to be made between parties and potential voters.

Meanwhile, Telangana’s new chief minister Revanth Reddy had promised to set aside four ministerial berths to women if voted to power. It was, said Chawla, “a refreshing change from the pure transactional nature of poll promises.” But at the swearing in, only two in the 12-member cabinet are women. It's early days yet, but nobody is holding their breath.

 


1) India vs Australia 5th T20I Highlights: IND beat AUS by six runs, win series 4-1:



 India (160/8) beat Australia (154/8) by 6 runs in Bengaluru to win series 4-1

India vs Australia 5th T20I Highlights: A superb bowling effort combined with Shreyas Iyer's gritty batting helped India beat Australia by six runs in the fifth and final T20I against Australia in Bengaluru. India, who were asked to bat first, piled 160/8 in 20 overs and Australia could only manage 154/8 in response.

Iyer smashed 53 off 37 balls and found some support from Jitesh Sharma and Axar Patel in the middle overs. Jitesh chipped in with 16-ball 24, while Axar scored 31 in 21 deliveries.

Mukesh Kumar and Ravi Bishnoi then made early injections as Australia lost both openers Travis Head and Josh Phillipe in the powerplay overs. Mukesh removed Phillipe for run a ball four, while Bishnoi cleaned up Head for 28(18). Australia, who are chasing 161, accumulated 50/2 at the end of powerplay. Bishnoi then removed Aaron Hardie for 6(10) in his next over.

Tim David and Ben McDermott then added 47 runs for the fourth wicket before Axar broke the stand. He removed David for run a ball 17. McDermott, on the other hand, completed his half-century before falling against Arshdeep Singh for 54(36). Mukesh Kumar then removed Matthew Short (16 off 11) and Ben Dwarshuis (0) in consecutive deliveries.

Matthew Wade kept Australia in hunt before getting out to Arshdeep Singh for 22(15) in the final over.Earlier, India got off to a brisk start before Australia crashed the party and removed openers Yashasvi Jaiswal and Ruturaj Gaikwad inside powerplay overs. Jaiswal was removed by Jason Behrendorff for 21(15), while Gaikwad fell for 10(12) against Ben Dwarshuis. Dwarshuis then got rid of Suryakumar Yadav in the next over, packing the Indian skipper for 5(7).

Australia continued to make inroads as Tanveer Sangha removed Rinku Singh for 6(8), reducing India to 55/4 in 9.1 overs.Both teams have made one change each in their playing XIs. Nathan Ellis got some game time and replaced Chris Green. Deepak Chahar, on the other hand, has flown back home due to medical emergency and is replaced by Arshdeep Singh.

2) Delayed wrestling federation polls to be held on Dec 21



The one-day process is expected to end months-long delay after protests by top wrestlers over alleged sexual harassment by Brij Bhushan Sharan Singh After a long delay due to court injunctions, the Wrestling Federation of India (WFI) election is finally scheduled to be held on December 21.Returning officer Justice (retd) MM Kumar on Saturday issued a fresh notification drawing up a revised schedule. According to it, the polling (during the WFI special general body meeting), counting and declaration of results will all be done in a single day. The election was originally scheduled on August 12. The nomination process was completed and the final list of candidates drawn up when the Punjab and Haryana high court stayed the election on a writ petition by the de-recognised Haryana federation.

The Supreme Court vacated the stay on November 28, paving the way for the process to resume. The court directed the returning officer to issue a revised election programme. The apex court order though stipulates that the results will be subject to the outcome of the plea pending before the high court.“The Hon’ble Supreme Court of India vide its order dated 28.11.2023 has vacated the stay orders and therefore the remaining steps like polling, etc. will now recommence on 21.12.2023 as per the following revised schedule,” said the notification, adding that as per WFI constitution 10 days’ notice has been given.

Outgoing WFI president and BJP MP Brij Bhushan Sharan Singh, who has been accused by six women wrestlers of sexual harassment and is facing trial in a Delhi lower court, still enjoys huge clout within the federation having governed WFI for 12 years. His supporters have filed nominations for all 15 posts. Singh’s close associate Sanjay Kumar Singh of Uttar Pradesh is standing for the president’s post.

A second group which has the support of wrestlers who protested against Singh is also in the fray for the top posts. Former wrestler and 2010 Commonwealth Games gold medallist, Anita Sheoran, who is with the Haryana Police official and is a witness in the sexual harassment case, is standing against Sanjay Singh. Railways Sports Promotion Board (RSPB) secretary Prem Chand Lochab – a key mediator between the protesting wrestlers and the government – is in the fray for the secretary general’s post, while former wrestler and senior superintendent with the Jammu and Kashmir Police, Dushyant Sharma, has pitched himself for the treasurer’s post.While Singh’s faction enjoys majority support, the possibility of a compromise on some of the key posts cannot be ruled out, according to people aware of the developments.

On Friday, the ad-hoc committee announced that the senior nationals will be hosted by RSPB in Jaipur from January 2-5. It will be the first domestic event to be organised after a 

The elections are important for the world body – United World Wrestling (UWW) -- to remove its suspension of WFI. Indian wrestlers currently can’t compete under the India flag because of the suspension. They took part as neutral athletes at the September world championships in Serbia. Antim Panghal won bronze and India’s first quota for the Paris Olympics.The wrestling fraternity will hope the elections to go off smoothly as it has already faced several delays due to the barred state associations petitioning the courts.

Last week, the Haryana Amateur Wrestling Association (HAWA) president Rohtas Singh appealed to the ad-hoc committee to go through the entire election process again, alleging that the final list of the electoral college and candidates flouted the government’s National Sports Code. He said some states need to be heard again with a “fresh schedule of election”.

3) Time running out for pistol shooters to book flight to Paris



Out of eight quotas for pistol events at the Paris Olympics, the Indian shooters have managed to grab just three so far A mind-boggling 1200 shooters participated in men’s air pistol event at the Senior National Championships in Bhopal culminating in the final on Thursday after 11 days of competition in just one event. The scores in the qualification round and final were world class — as high as the World Championships in Baku this year. Encouraging it might seem just seven months before the Paris Olympics, but the reality is different. There is still an Olympic quota to be won from the event and there is no guarantee that such high scores will be replicated in the next international competition, which will be a Paris Olympic qualifier in Jakarta in January.

Going into the Tokyo Olympics, India had all four quotas in their kitty and it was the air pistol team, including the mixed

4) India slip to third in pool after going down 1-4 to Spain in their Junior World Cup hockey match in Kuala Lumpur:



Spain thrashed India 4-1 in their group match ongoing Junior World Cup to go top of the table in Pool C, in Kuala Lumpur on Friday. Both India and Spain were coming off convincing wins in the previous encounters — India had beaten South Korea 4-2 on Tuesday while Spain blanked Canada 7-0 — but Spain, led by braces from skipper Rafi Andreas and Cabre Verdiell Pol, proved too hot to handle for India.

Spain got off the blocks early and found the opening goal in the first minute itself through an unmarked Pol who beat goalkeeper Shashikumar Honnenahalli with a lovely deflection. Rohit drew level for India in the 33rd minute through a penalty corner but a tactically superior Spain were significantly better than the Indians who appeared jaded on the pitch.

Spain were superb on the wings and played a close-knit game, allowing little room to the Indian forwards. Andreas restored the lead for Spain in the 18th minute through a PC before Pol converted another PC in the 41st minute. Andreas then put the result beyond doubt with a penalty stroke in the last minute of regulation time to unwittingly underscore his team's domination from the first minute to the last.

Spain goalkeeper Capellades Jan stood out for his pluck and anticipation, saving a handful of sure-shot strikes from Indian forwards.

India earned three penalty corners between the 55th and 57th minutes but Capellades put his body on the line to deny them success.

Overall, India had more circle penetrations (18 to Spain's 16) and penalty corners (six to Spain's seven) but Spain had more shots on goal (13 as compared to India's 10) and, eventually, goals. Spain pressed with pace and scored in each quarter while the 2016 champions were left chasing the game. India will next play Canada on Saturday while Spain will square off against South Korea. India and Korea are currently level on points but the latter occupy the second spot in Pool C owing to better goal difference. Canada, with two losses in as many outings, occupy the fourth spot.

5) Squash's Olympics tag adds wheels to Anahat's go pro drive



The 15-year-old, fresh from her twin medals in Hangzhou Asian Games, is happy to take a step-by-step approach to the Olympics

Moments after squash was included as one of the new sports for the 2028 Los Angeles Olympics at October's IOC Session in Mumbai, Saurav Ghosal, India's top squash professional aged 37, chuckled that he wished he was 10 years younger.Moments after squash was included as one of the new sports for the 2028 Los Angeles Olympics at October's IOC Session in Mumbai, Saurav Ghosal, India's top squash professional aged 37, chuckled that he wished he was 10 years younger.Anahat Singh, the reigning women’s national champion, is 15. This year's U-17 Asian junior gold medallist, she grabbed a couple of medals at the Hangzhou Asian Games — a bronze each in the women's team and mixed doubles with Abhay Singh. By far the brightest young talent in the country’s squash circuit, the soft-spoken teen from Delhi felt the timing of the belated Olympics tag couldn’t have been better from an Indian perspective, having come days after the squash contingent’s creditable five-medal Asian Games show.

“It was almost like a miracle. Really exciting," said Anahat, the glee on her face while talking about it truly bringing out her age. What follows, however, is another reminder of her being unlike many other 15-year-olds. “I was always somewhat sure that I would want to go pro. I really love playing this sport. But yes, this (Olympics inclusion) does give me a definite direction. It's going to be a target which I'm going to be working towards for the next five years," said Anahat sitting by the squash courts of Cricket Club of India here on Thursday.

"I know for the next five years that I'm going to be 100% serious about squash because the Olympics will be the next big goal. So, it does change my approach quite a bit — in terms of the amount of training and the amount of work that I'm going to put in. Because it is an athlete's dream to win a medal at the Olympics.”

At 15, Anahat has already been to the Commonwealth Games and Asian Games, richer with experience from the former and medals from the latter. She has pocketed age-group medals at the prestigious British Junior Open (U-11 in 2019 and U-17 in 2023) and US Junior Open (U-15 in 2021), ticking off boxes that the stars of Indian squash — Ghosal, Joshna Chinappa and Dipika Pallikal Karthik — did in their junior days. For her age, it’s about those little steps, although Anahat isn’t shying away from drawing out a five-year plan.

“I mean, I do have to look at it from the long-term view. I'm still playing the juniors for the next three years, so it has to be step by step and tournament by tournament. At the same time, that is going to be the long-term goal: to win a medal at the Olympics. But before that there are other things as well, like winning PSA (Professional Squash Association) tournaments and some top junior events,” she said.won the 2023 title after Tanvi Khanna retired in the final and lost the 2022 final to Joshana), one of Anahat’s goals for next year is to start competing in more PSA world tour events to climb up the world rankings. “I'm going to start playing more of the senior tournaments and less junior events," she said.

Juggling both this year has meant her “tournaments have almost doubled”. Right after the Asian Games, she turned up for the senior nationals last month. Currently in Mumbai for the CCI-Western India Slam Squash Championship, she will head out for another junior tournament later this month. The difference in level from the juniors to seniors is evident for Anahat, who believes playing the latter has helped her while competing in the top junior world events.“Seniors is a lot more physical. There, your whole career is squash, you're working towards it day and night and everyone wants to just win no matter what," she said. “The amount of training that the seniors do, the precision of their shots and their fitness overall is much better than the junior level.”

BOOK OF THIS WEEK:







THE FUTURE OF THE MIND:by Michio Kaku (Author),

Throughout human history – Scientists have sought to unlock the secrets of the human mind and Dr. Michio Kaku, noted theoretical physics, bestselling author and the co-founder of string field theory, says thanks to new breakthroughs in neural mapping,we’re on the fron

tier of a new era in understanding the human brain.

“We can now put a chip right on top of the brain of a person who is totally paralyzed and have them control the cursor on a laptop, so that person who starts the soccer tournament in Brazil may be a paraplegic.”

In his book, THE FUTURE OF THE MIND, Kaku investigates multiple breakthrough ideas in neuroscience,  many of which were once considered sheer fantasy or even science fiction. Ideas like telepathy, telekinesis, mind reading, uploading our memories… and even shooting human consciousness into space.

Dr. Kaku says many of these ideas, which were once considered impossible have now been achieved in the laboratory. One of the most fascinating new technologies has allowed scientists to record something never recorded before…a persons dream.

“What happens is, you have to fall asleep in an MRI machine, and then it scans your brain and creates a picture and these pictures are remarkable. They’re fuzzy of course, but you can actually see eyes, noses, you can see an elephant is an elephant and a human is a human. But the very fact that you can even do this is astounding and it means that in the future when you wake up in the morning you can hit the play button on your computer and watch the dream you had last night.”

Watch video footage of a recorded dream

Dr. Kaku says last year for the first time in world history, the first memory of a mouse was recorded on tape. You could actually play the memory back.The memory was sipping water from a container. It wasn’t a very complex memory, but the fact you could do it at all means that one day we might have something like the Matrix, whereby you could become a Karate master simply by hitting a play button.”This leads to the question of privacy. Are people going to be able to read our minds and record or dreams against our will?“That’s not going to happen. Brain waves dampen extremely rapidly outside the skull, so don’t think the CIA is going to be able to tap into your thoughts from the outside. That’s not going to happen.”

So, what can we do with all these recorded dreams and memories? Another seemingly impossible new technology in Dr Kaku’s book may allow scientists

to upload the data in our brains and shoot it on a laser beam across space.“Then we wouldn’t need expensive booster rockets. We would go literally at the speed of light on a laser beam containing all this vast amount of information, and go to a relay station, whereby you construct a robot which then springs to life. ”Sounds like pure science fiction, but Dr. Kaku insist it could become scientific fact.“So many of the themes of science fiction are still science fiction of course, but the fact we can talk about some of them in a scientific way is amazing.”

Dr Michio Kaku says all these new breakthroughs in neuroscience will not only help us explore new horizons in outer space,  but also more internal problems right here on earth. Problems like the many mental disabilities that plague society today,  depression, autism, schizophrenia, all of which remain largely unsolved mysteries.  Dr. Kaku hopes making headway in

these areas will help create a world where peoples innate talents and abilities“So many times we have hopes and dreams that are dashed by illness, by poverty, by disease, and we don’t live up to our full potential. What we’re capable of being and becoming. So why do we have to be victims of this, when one day science may be able to unleash us, so that we fulfill our destiny.

Michio Kaku:

Michio Kaku is the co-founder of String Field Theory and is the author of international best-selling books such as Hyperspace, Visions, and Beyond Einstein. Michio Kaku is the Henry Semat Professor in Theoretical Physics at the City University of New York.
