Bacillus
anthracis bacteria have very efficient machinery for injecting toxic proteins
into cells, leading to the potentially deadly infection known as anthrax. A team
of MIT researchers has now hijacked that delivery system for a different
purpose: administering cancer drugs."Anthrax toxin is a professional at
delivering large enzymes into cells," says Bradley Pentelute, the
Pfizer-Laubauch Career Development Assistant Professor of Chemistry at MIT.
"We wondered if we could render anthrax toxin nontoxic, and use it as a
platform to deliver antibody drugs into cells."
In a
paper appearing in the journal ChemBioChem, Pentelute and colleagues showed
that they could use this disarmed version of the anthrax toxin to deliver two
proteins known as antibody mimics, which can kill cancer cells by disrupting
specific proteins inside the cells. This is the first demonstration of
effective delivery of antibody mimics into cells, which could allow researchers
to develop new drugs for cancer and many other diseases, says Pentelute, the
senior author of the paper.
Hitching
a ride
Antibodies
-- natural proteins the body produces to bind to foreign invaders -- are a
rapidly growing area of pharmaceutical development. Inspired by natural protein
interactions, scientists have designed new antibodies that can disrupt proteins
such as the HER2 receptor, found on the surfaces of some cancer cells. The
resulting drug, Herceptin, has been successfully used to treat breast tumors
that overexpress the HER2 receptor.Several antibody drugs have been developed
to target other receptors found on cancer-cell surfaces. However, the potential
usefulness of this approach has been limited by the fact that it is very
difficult to get proteins inside cells. This means that many potential targets
have been "undruggable," Pentelute says.
"Crossing
the cell membrane is really challenging," he says. "One of the major
bottlenecks in biotechnology is that there really doesn't exist a universal
technology to deliver antibodies into cells."
For
inspiration to solve this problem, Pentelute and his colleagues turned to
nature. Scientists have been working for decades to understand how anthrax
toxins get into cells; recently researchers have started exploring the
possibility of mimicking this system to deliver small protein molecules as
vaccines.The anthrax toxin has three major components. One is a protein called
protective antigen (PA), which binds to receptors called TEM8 and CMG2 that are
found on most mammalian cells. Once PA attaches to the cell, it forms a docking
site for two anthrax proteins called lethal factor (LF) and edema factor (EF).
These proteins are pumped into the cell through a narrow pore and disrupt
cellular processes, often resulting in the cell's death.
However,
this system can be made harmless by removing the sections of the LF and EF
proteins that are responsible for their toxic activities, leaving behind the
sections that allow the proteins to penetrate cells. The MIT team then replaced
the toxic regions with antibody mimics, allowing these cargo proteins to catch
a ride into cells through the PA channel.
'A
prominent advance'
The
antibody mimics are based on protein scaffolds that are smaller than antibodies
but still maintain structural diversity and can be designed to target different
proteins inside a cell. In this study, the researchers successfully targeted
several proteins, including Bcr-Abl, which causes chronic myeloid leukemia;
cancer cells in which that protein was disrupted underwent programmed cell
suicide. The researchers also successfully blocked hRaf-1, a protein that is
overactive in many cancers.
"This
work represents a prominent advance in the drug-delivery field," says
Jennifer Cochran, an associate professor of bioengineering at Stanford
University. "Given the efficient protein delivery Pentelute and colleagues
achieved with this technology compared to a traditional cell-penetrating
peptide, studies to translate these findings to in vivo disease models will be
highly anticipated."The MIT team is now testing this approach to treat
tumors in mice and is also working on ways to deliver the antibodies to
specific types of cells.
2) Fossil
of ancient multicellular life sets evolutionary timeline back 60 million years:
A
Virginia Tech geobiologist with collaborators from the Chinese Academy of
Sciences have found evidence in the fossil record that complex multicellularity
appeared in living things about 600 million years ago -- nearly 60 million
years before skeletal animals appeared during a huge growth spurt of new life
on Earth known as the Cambrian Explosion.
The
discovery published online Wednesday in the journal Nature contradicts several
longstanding interpretations of multicellular fossils from at least 600 million
years ago."This opens up a new door for us to shine some light on the
timing and evolutionary steps that were taken by multicellular organisms that
would eventually go on to dominate the Earth in a very visible way," said
Shuhai Xiao, a professor of geobiology in the Virginia Tech College of Science.
"Fossils similar to these have been interpreted as bacteria, single-cell
eukaryotes, algae, and transitional forms related to modern animals such as
sponges, sea anemones, or bilaterally symmetrical animals. This paper lets us
put aside some of those interpretations."In an effort to determine how,
why, and when multicellularity arose from single-celled ancestors, Xiao and his
collaborators looked at phosphorite rocks from the Doushantuo Formation in
central Guizhou Province of South China, recovering three-dimensionally
preserved multicellular fossils that showed signs of cell-to-cell adhesion,
differentiation, and programmed cell death -- qualities of complex multicellular
eukaryotes such as animals and plants.
The
discovery sheds light on how and when solo cells began to cooperate with other
cells to make a single, cohesive life form.
The
complex multicellularity evident in the fossils is inconsistent with the
simpler forms such as bacteria and single-celled life typically expected 600
million years ago.While some hypotheses can now be discarded, several
interpretations may still exist, including the multicellular fossils being
transitional forms related to animals or multicellular algae.Xiao said future
research will focus on a broader paleontological search to reconstruct the
complete life cycle of the fossils.Xiao earned his bachelor's and master's
degrees from Beijing University in 1988 and 1991 and his doctoral degree from
Harvard University in 1998. He worked for three years at Tulane University
before arriving at Virginia Tech in 2003.
3) Water
found on Neptune-sized world:
HAT-P-11b
is smallest exoplanet known to host the life-friendly molecule. The smallest,
coolest exoplanet known to host water is roughly the size of Neptune,
astronomers report in the Sept. 25 Nature. Previously, researchers had found
water only on exoplanets that are about the size of Jupiter. The planet
HAT-P-11b is just over four times as wide as Earth.
Jonathan
Fraine, an astronomer at the University of Maryland in College Park, and
colleagues discovered the water after a year and a half of observations with
the Hubble, Spitzer and Kepler space telescopes.
Gases
such as water vapor in a planet’s atmosphere leave their mark by absorbing
specific frequencies of light. When HAT-P-11b comes between Earth and its star,
the planet’s atmosphere filters out some of the starlight. The astronomers
detected water by observing infrared light that disappeared each time the
planet passed between Earth and its host, an orange dwarf about 122 light-years
away in the constellation Cygnus.
The data
also revealed a relatively clear atmosphere that is rich in hydrogen. The
abundance of hydrogen jibes with theories of planet formation, in which gas
giants form around a rocky or icy core that quickly attracts an atmosphere by
pulling hydrogen out of the gaseous disk encircling an infant star.
Snakes on
a plane” might be a good strategy for building rescue robots.
Pairing
two snakelike robots with a flying one has let researchers combine the
exploring skills of small, ground-based bots with the swift moves of an aerial
machine.Engineers have created search-and-rescue robots before — tanklike
machines with heavy-duty treads — but most of these bots muscle over rough
terrain with brute force. They can disturb damaged areas and have trouble
reaching nooks and crannies within the wreckage.
Agile
snakebots can burrow through rubble, but they can get stuck, said Stella
Latscha, a University of Pennsylvania mechanical engineer now at SpaceX in
Hawthorne, Calif. “If a person has to run out and move them that really defeats
the purpose.” So she and colleagues designed a four-propeller helicopter that
can airlift wheeled snakebots out of tight spots.
The robot
trio speeds over flat terrain as a team, or splits up to patrol the air and the
ground separately. Using an Xbox controller, Latscha and colleagues drove
snakebots through a 4-inch pipe and even up stairs.
For
faster vertical trips, the rolling bots use magnets to snap into the
helicopter, which can fly carrying one snakebot for about five minutes, the
researchers reported September 16 at the IEEE/RSJ International Conference on
Intelligent Robots and Systems.
In our
bodies, our cells are constantly dividing in order to replenish our lungs,
skin, liver and other organs. But most human cells can’t divide forever, and
eventually this causes our organs and tissues to degrade as we age.The
"timekeeper" of our cells are telomeres - little DNA caps that sit at
the end of our chromosomes, sort of like that plastic bit at the end of your
shoelace. Each time a cell divides, these telomeres get shorter and shorter
until eventually they're so short the cell can no longer divide.
But
researchers know that there is a way to stop the telomere from wearing down -
some cells can produce an enzyme called telomerase, which rebuilds telomeres
and lets cells divide indefinitely. However they've struggled to understand why
telomerase acts in some cells and not others.
Now
researchers from the Salk Institute for Biological Studies in the US have
discovered that telomerase has an on/off switch - and can be present in a cell
but not slow down ageing if it's turned off.“Previous studies had suggested
that once assembled, telomerase is available whenever it is needed,” senior
author Vicki Lundblad said in a press release. “We were surprised to discover
instead that telomerase has what is in essence an ‘off’ switch, whereby it
disassembles.” Their research is published in the journal Genes and
Development.It’s a pretty huge breakthrough, because if scientists can now work
out how to manipulate this “off” switch, it could help them slow down the
ageing process and lead to treatments for age-related diseases. And,
interestingly, it may also provide insight into cancer cells, which require
telomerase to help them divide uncontrollably.
Lundblad,
along with graduate student Timothy Tucey, discovered this switch in yeast, by
using a new technique that allowed them to monitor each component of telomerase
while a cell grew and divided.
Each time
a cell divides, its genome must be duplicated completely. And the scientists
found that while a cell was replicating, telemorase was sitting in a
“preassembly” mode, waiting for a molecular subunit to be added once genome
duplication was complete.But surprisingly, as soon as the telemorase was
assembled, it quickly disassembled and switched into the “off” position, they
discovered. The researchers believe that this off switch might help the body
keep telomerase at exceptionally low levels inside the cells in order to avoid
the uncontrollable cell growth that can lead to cancer. But it could also be
the key to helping cells divide for longer.While it might not seem as though
these experiments in a single-celled yeast can tell us much about human cells,
much of the initial research on telomerase was done in yeast cells and laid the
groundwork for future discoveries in humans.The next step is to understand more
about this switch and how it is involved in ageing and cancer, and then
scientists can try to understand how it can be manipulated to keep people
healthier for longer.

Political
News This Week:
1) It's
official: 25-year-old BJP, Shiv Sena alliance in Maharashtra ends:
The
25-year-old Bharatiya Janata Party-Shiv Sena alliance split on Thursday amid
continued deadlock over seat-sharing for the October 15 Maharashtra assembly
polls. After several rounds of talks over the last few days, senior state BJP
leaders announced this evening severing of the ties between the two parties,
blaming Shiv Sena's "inflexibility" for it.
"We
have conveyed our decision to snap ties to the Shiv Sena. The decision was
taken with a heavy heart," Maharashtra BJP chief Devendra Fadnavis told
reporters after a meeting of the state party's core committee.The BJP, however,
hinted at the possibility of a post-poll alliance with its estranged ally,
saying the party would not criticise the Sena during the campaign and remain
friends."Our aim is to prevent the corrupt Congress-Nationalist Congress
Party government from coming to power. We will not criticise Shiv Sena during
the campaign, we don't want any bitterness with our ally of 25 years,"
Leader of Opposition in the assembly Eknath Khadse said.
Fadnavis
said the BJP will go to polls with smaller 'Mahayuti' allies. He said BJP had
worked out a seat-sharing deal with Mahadeo Jankar's Rashtriya Samaj Paksha and
Raju Shetty's Swabhimani Shetkari Sanghatana.“Our talks with Vinayak Mete of
Shiv Sangram are in final stages and we will also speak to RPI's Ramdas
Athawale, Fadnavis said."We reiterate that the Shiv Sena is still our
friend. We will not criticise the Sena and our target will be the corrupt
Congress-NCP combine," he said.
2) Assam
flood death toll rises to 36; 10 lakh affected:
With the
recovery of four more bodies on Thursday, the death toll mounted to 36 in Assam
floods that affected about 10 lakh people in 13 districts and rendered majority
of them homeless.Two more deaths were reported from Krishnai and Kukurkata
areas of the worst-hit Goalpara district, while one body each was recovered from
Tinsukia district and Guwahati which falls in Kamrup Metro district, officials
said.Chief Minister Tarun Gogoi said 35 to 36 people have been reported dead so
far and that the toll could be higher. Though the rains have stopped and water
was slowly ebbing, huge tracks of human habitation and crop fields were under
water that reached even up to roofs of thatched- and tinned-roof houses, the
officials said.
The
authorities have opened 162 relief camps and shelter homes where 1.5 lakh
people have taken shelter. The National Highway in Goalpara was still under
water and there was no movement of traffic there, while washing away of a
wooden bridge on Aagia-Darek Road has forced the people to come to safety using
a rope from one bank to the other.
The
floods have caused four small children in Boko area of Kamrup Rural district to
become orphans as their parents were washed away by a swollen river, the
sources said. With the cessation of rains since last evening in Guwahati, the
flood waters were gradually receding from Anil Nagar, Nabin Nagar and Zoo Road
areas, the sources said.
According
to the flood report by Assam State Disaster Management Authority, around 3 lakh
people were hit in Kamrup Rural district. Essential food items and tarpaulin
sheets were being provided to the relief camp inmates, the ASDMA release said.
However, people who took shelter on higher roads complained that the
authorities have not provided them with food, drinking water or tarpaulin
sheets.
Goalpara
district was the worst-hit in the floods due to heavy rains in Assam, Meghalaya
and Arunachal Pradesh since early this week, while torrential downpour and
water running down from the adjacent Meghalaya hills caused heavy waterlogging
in Guwahati, the sources said.
Several
embankments have been breached and many roads damaged across the state, the
ASDMA added. The worst hit Goalpara district recorded the maximum death (16),
followed by Kamrup Rural (12), Kamrup Metro (six), Dhubri and Tinsukia (both
one).The other affected districts are Dhemaji, Barpeta, Udalguri, Kokrajhar,
Nalbari, Morigaon, Nagaon, Darrang and Lakhimpur.The state government had on
Wednesday announced an ex-gratia payment of Rs 3.5 lakh to the next of kin of
those who died in the flood. Meanwhile, the Northeast Frontier Railway had
cancelled eight trains on Wednesday and diverted seven others today due to the
floods in Lower Assam and damaged track restoration work.
The
railway will also operate three special trains for transporting flood-affected
people and helping in restoration work, an NF Railway spokesperson said in a
statement. Rail tracks were breached at 16 places in the New
Bongaigaon-Goalpara-Kamakhya section of Rangiya Division due to massive flood
during the last few days, the statement said.Track restoration work is also
going on between Aujuri and Sonuabari in Lumding division, the spokesman added.
3) Scores
injured in fire at SAIL's West Bengal plant; 2 in ICU:
A fire at
SAIL's IISCO Steel Plant at Burnpur, West Bengal, injured 21 people, with 2 of
them in ICU, the state-owned steel maker said on Thursday. All the affected are
being provided with immediate medical care, it said.
"An
incident of fire occurred at SAIL’s IISCO Steel Plant at 12.15 pm... Around 21
affected persons have been provided immediate medical attention, both at the
Plant Medical Unit and at Burnpur hospital. Out of these, two persons belonging
to contractor BEC have been admitted to ICU," SAIL said in a statement.
Preliminary
enquiry has revealed that it happened in New Coke Oven Battery no 11, it
said.The fire was immediately extinguished. The incident occurred during a
planned shutdown taken for carrying out rectification jobs in one of the
pre-heaters of the coke oven battery.
4) Coal
scam whistleblower MP: Manmohan Singh is the biggest culprit:
The UPA
government should have cancelled the coal allocations after the CAG report was
tabled in 2012. Instead, its ministers ridiculed the CAG report and the losses
enumerated in it. They thus lost a very important opportunity to stop and
contain the national loss,' BJP MP Hansraj Ahir, who red-flagged the issue in
2005, The Supreme Court on September 24 quashed the allocation of 214 out of
218 coal blocks which were allotted to various companies since 1993.
Hansraj
Ahir, the Bharatiya Janata Party member of Parliament, who had blown the
whistle on the coal scam way back in 2005, feels vindicated. Are you happy with
the Supreme Court verdict?
I
wholeheartedly welcome the Supreme Court verdict. It is an excellent verdict
delivered by the apex court that will stop the loot of natural resources that
the country has seen. The verdict has upheld the dignity of the highest court
in India.
I have
been fighting against this loot since 2006.
When did
you first detect that there was a scam brewing in the allocation of coal
blocks?
In 2004,
I became the member of the Standing Committee on Coal and Steel. After going
through documents I realised that there was something improper about these coal
allocations.I continued studying various documents and registered my first
complaint in 2005 to Shibu Soren (then the coal minister). But the complaint
was only about the coal block allocation in Maharashtra (Ahir is the MP from
Chandrapur).Later, when I delved further into the issue and laid hands on
certain official documents, I found out that these blocks were doled out for
free.In 2006, I wrote letters to P Chidambaram (then the finance minister) and
(then Planning Commission deputy chairman) Montek Singh Ahluwalia. I asked them
to levy some surcharge on the coal mined to generate some revenues; they
responded very positively.
Ahluwalia
prepared a Planning Commission report on the matter and sent it to the prime
minister. Chidambaram also agreed with the proposal, but then they poured cold
water on this proposal.
When they
did not pursue the matter further I started writing to the PM.
What was
the outcome of your letters to Dr Manmohan Singh?
I started
writing letters to Dr Manmohan Singh in 2006 in which I objected to free
disbursal of natural resources like coal.
While
Chidambaram and Ahluwalia did acknowledge my letters and my standpoint, Dr
Singh just acknowledged that he was in receipt of my letters.
I still
have those 15 letters with me that I had written to him.
It was
only when the report of the Comptroller & Auditor General of India came out
that the government started taking some cognisance of the matter.
When the
CAG report came out, why didn't you file a public interest litigation?
In my
opinion, the matter should not have reached the Supreme Court in the first
place. That is the reason I never felt it necessary to file a PIL.
The then
government should have cancelled the coal allocations after the CAG report was
tabled in 2012.
Instead,
all UPA ministers, including Salman Khurshid and then minister for coal
Sriprakash Jaiswal, ridiculed the CAG report and the losses enumerated in it.
They
should have taken cognisance of the 2012 CAG report and cancelled the
allocations two years ago.
They lost
a very important opportunity to stop and contain the national loss.
Who do
you hold responsible for this coal block allocation scam?
Dr
Manmohan Singh is the biggest culprit. While I reiterate and welcome the
Supreme Court decision, there are 20 more crimes that still needs to be
investigated.
Chief
among them being:
Damaging
the efficiency of Coal India with a criminal purpose
Conspiracy
to finish off Coal India
Many Coal
India office bearers resigned from the company and joined private companiesBecause
of all these crimes the nation had to face a huge shortfall of coal
availability and so import it, leading to outflow of foreign exchange.
There was
a big conspiracy to undermine India's self-sufficiency and kill Coal India. I
think all this has come out today after the cancellation of these 214 coal
blocks.
More than
the politicians of the day and industrialists, I hold the coal ministry and top
officials of Coal India responsible for the entire mess.Sriprakash Jaiswal,
Santosh Bagrodia, Shibu Soren and Dasari Narayan Rao are all equally
responsible for this national loot of coal resources.Of course, the biggest of
them all who should take the responsibility is Dr Manmohan Singh.
You blame
Coal India for this scam.Right from the chairman and managing director to board
directors there were 11 members of Coal India who would be part of the
screening committees that made recommendations for allocations of coal blocks
to various companies.
Former
coal secretary P C Parakh also said the same thing that I had written in my
letters about these members of Coal India.But he said nothing during his tenure
as coal secretary and opened his mouth only after retirement.Where do you think
the CBI inquiry into the coal scam is heading now? Do you think the
investigations are being done fairly?
I would
not like to comment on this. Now that the Supreme Court has given its verdict
that the coal block allocations were done in an illegal and ad hoc manner, the
CBI's responsibility has increased manifold.The CBI's dignity and fairness are
at stake now.
5) After
making history, Mangalyaan begins its true work:
It’s been
just a few hours since India’s first interplanetary mission, the Mars orbiter,
entered the red planet’s orbit successfully and it is already hard at work.The
Mangalyaan has sent back five photographs of Mars. The Indian Space Research
Organisation confirmed that their ground station had receieved the first set of
data from the craft.
The Mangalyaan
had successfully entered the Mars's orbit early on Wednesday morning, making
India the first country in the world to send a spacecraft to Mars in its maiden
attempt.
The
country joined the United States, European Space Agency and the former Soviet Union
in the elite club of Martian explorers with the Mars Orbiter Mission,
affectionately called MOM.“History has been created by our scientists,” said
Prime Minister Narendra Modi in his speech immediately after the scientists
declared the mission a success. “We have dared to reach out to the unknown.”
MOM's
scientific goals including using five solar-powered instruments to gather data
that will help determine how Martian weather systems work and what happened to
the water that is believed to have once existed on Mars in large quantities. It
will also search Mars for methane, a key chemical in life processes on Earth
that could also come from geological processes.
Meet the
men behind the Mars Mission:
K
Radhakrishnan: Indian Space Research Organisation chairman and department of
space secretary. He became chairman in 2009, and was awarded the Padma Bhushan
in 2014.
Mylswamy
Annadurai: Programme director of Mangalyaan. He was leading the remote
sensing and science missions; responsible for budget management, direction for
spacecraft configuration, schedule and resources. He was the project director
of Chandrayaan-1 and now Chandrayaan-2.
S
Ramakrishnan: Director at the Vikram Sarabhai Space Centre. He is one of the
key brains in the development of PSLV and is responsible for development of
liquid propulsion stages and their interfacing with vehicle and launch
operations. He is responsible for realising the PSLV that ferried Mars orbiter.
Shivkumar: Director
of ISRO Satellite Centre, developed the telemetry system for MOM.
V
Adimurthy: Mission concept designer of MOM.
P
Kunhikrishnan: Project director of PSLV Programme. He was the mission director
of eight successful PSLV Missions. He is the mission director of PSLV-C25/MOM.
He was responsible for seeing the rocket complete its mission successfully
Subbiah
Arunan: Project director of MOM. He was responsible for building the
spacecraft.
B
Jayakumar: Associate project director of PSLV project, responsible for the
rocket systems. Chief general manager of range operation at Sriharikota Rocket
port. He was responsible for maintaining launch schedules without any
slippages.
The view
is nice up here: Mangalyaan tweets first photo:
India’s
Mars Orbiter Mission spacecraft has sent in its first images of the Red Planet
after creating history by becoming the only such endeavour so far to have met
with success on the maiden attempt.“First image of Mars, from a height of 7,300
kilometre; with 376 m spatial resolution. MT @MarsOrbiter. The view is nice up
here,” Indian Space Research Organisation said on Thursday in a tweet posted
along with snaps of the red planet.
India
successfully placed its low-cost Mars Orbiter Mission spacecraft in orbit
around the red planet in its very first attempt on Wednesday, breaking into an
elite club of three nations.The spacecraft is now circling the red planet in an
orbit whose nearest point to Mars (periapsis) is at 421.7 kilometre and
farthest point (apoapsis) at 76,993.6 km, ISRO said.
The
inclination of orbit with respect to the equatorial plane of Mars is 150
degree, as intended. In this orbit, the spacecraft takes 72 hours 51 minutes 51
seconds to go round Mars once.In the coming weeks, ISRO said in a release, the
spacecraft will be thoroughly tested in the Mars orbit and the systematic
observation of that planet using its five scientific instruments would
begin.MOM aims to study the Martian surface and mineral composition and scan
its atmosphere for methane, an indicator of life.
The
spacecraft is equipped with five instruments, including a sensor to track
methane or marsh gas, a colour camera and a thermal-imaging spectrometer to map
the surface and mineral wealth of the red planet.The Rs 450-crore MOM is the
cheapest inter-planetary mission. India is the first country to reach Mars in
the very first attempt. European, American and Russian probes have managed to
orbit or land on the planet, but after several attempts.
The
orbiter will keep moving in an elliptical path for at least six months with its
instruments sending their gleanings back home.
The
spacecraft was launched on its nine-month-long odyssey on a homegrown PSLV
rocket from Sriharikota in Andhra Pradesh on November 5 of last year. It had
escaped the earth’s gravitational field on December 1.
Jayalalithaa convicted, sentenced to 4 yrs in Jail; 100 cr fine:
Tamil Nadu Chief Minister J Jayalalithaa was on Saturday convicted and sentenced to four years jail in an 18-year-old corruption case in a judgment that will unseat her from the post, disqualified her immediately as an MLA and can impact the Assembly elections due in 18 months.Since she has been sentenced to a term of more than 3 years, the chief minister has been taken to jail and she can apply for bail only from Karnataka High Court.
The 66-year-old AIADMK supremo has also been slapped with a fine of Rs 100 crore, highest imposed on any politician, by a special judge John Michael D'Cunha who heard the case of Rs 66.65 crore disproportionate assets acquired during her first term as chief minister between 1991 and 1996.
The conviction in the high-security court complex of Parappana Agrahara near here came amidst dramatic scenes outside where AIADMK supporters burnt effigies of DMK leader Karunanidhi and Subramaniam Swamy who had initially raked up the case.The conviction also evoked sporadic violence in Tamil Nadu where public vehicles were attacked and shops closed.
The Directorate of Vigilance and Anti-corruption had filed a charge sheet in the case which was transferred to the court here in 2003.
The court also convicted three others--Jayalalithaa's close friend Sasikala, Sasikala's niece Ilavarasi and her nephew and Chief Minister's disowned foster son Sudhakaran--and sentenced them to four years of jail term.Special Public Prosecutor Bhavani Singh said a sum of Rs 10 crore has been imposed on the other three convicts. He said the four can apply for bail by moving an application before the High Court.
Under a Supreme Court judgment of July last year, any MP or MLA who is convicted of a crime with more than two-years sentence will be disqualified as an elected representative from the date of conviction.
Unless the conviction is stayed or overturned by a superior court, she will be disqualified under the Representation of the People Act from contesting elections for a period of 10 years--four years from the date of conviction and six years thereafter.
Jayalalithaa has had the dubious distinction of having to resign in 2001 following a Supreme Court judgment that nullified her appointment in view of her conviction in TANSI land deal case.
The verdict immediately triggered speculation as to who will replace Jayalalithaa as Chief Minister.The names of senior minister O Panneerselvam, who had taken over as Chief Minister in 2001 after she was unseated and till her return, Transport Minister V Senthil Balaji and Electricity Minister R Viswanathan and even former Chief Secretary Sheela Balakrishna are doing the rounds.The verdict has come as a jolt to the ruling AIADMK as it had been enjoying a winning spree in all the elections held since April 2011, when the party trounced DMK.
The party had put up a stellar performance in the Lok Sabha polls this year, winning 37 of the 39 states in the state, though its hopes of a pivot role in the Centre failed with the BJP mustering majority on its own.However, there is no threat to the party government as AIADMK has a solid majority of 150 seats in the 234-member Assembly.She had been acquitted in several other cases filed during the DMK regime.
Jayalalithaa convicted, sentenced to 4 yrs in Jail; 100 cr fine:
Tamil Nadu Chief Minister J Jayalalithaa was on Saturday convicted and sentenced to four years jail in an 18-year-old corruption case in a judgment that will unseat her from the post, disqualified her immediately as an MLA and can impact the Assembly elections due in 18 months.Since she has been sentenced to a term of more than 3 years, the chief minister has been taken to jail and she can apply for bail only from Karnataka High Court.
The 66-year-old AIADMK supremo has also been slapped with a fine of Rs 100 crore, highest imposed on any politician, by a special judge John Michael D'Cunha who heard the case of Rs 66.65 crore disproportionate assets acquired during her first term as chief minister between 1991 and 1996.
The conviction in the high-security court complex of Parappana Agrahara near here came amidst dramatic scenes outside where AIADMK supporters burnt effigies of DMK leader Karunanidhi and Subramaniam Swamy who had initially raked up the case.The conviction also evoked sporadic violence in Tamil Nadu where public vehicles were attacked and shops closed.
The Directorate of Vigilance and Anti-corruption had filed a charge sheet in the case which was transferred to the court here in 2003.
The court also convicted three others--Jayalalithaa's close friend Sasikala, Sasikala's niece Ilavarasi and her nephew and Chief Minister's disowned foster son Sudhakaran--and sentenced them to four years of jail term.Special Public Prosecutor Bhavani Singh said a sum of Rs 10 crore has been imposed on the other three convicts. He said the four can apply for bail by moving an application before the High Court.
Under a Supreme Court judgment of July last year, any MP or MLA who is convicted of a crime with more than two-years sentence will be disqualified as an elected representative from the date of conviction.
Unless the conviction is stayed or overturned by a superior court, she will be disqualified under the Representation of the People Act from contesting elections for a period of 10 years--four years from the date of conviction and six years thereafter.

5) Sunset
in the east: Abhinav Bindra signs off from Asian Games with twin bronze :
One of
the enduring images, from India’s perspective, of the Beijing Olympics was that
of Zhu Qinan being reduced to tears at a press conference minutes after being
humiliated in front of the home crowd by Abhinav Bindra. Next morning, the
country’s leading English newspaper, China Daily, ran a huge picture of Bindra
on its front page with a headline — which had an undertone of a taunt — that read:
‘A nation of a billion people wins its first gold.’ Unfortunately for Bindra,
he hasn’t beaten a shooter from that other nation of a billion plus people
since that historic Monday morning half a dozen years ago. Qinan exacted
revenge at the range by winning the Guangzhou Asiad gold two years later —
giving birth to an interesting duel; a cat-and-mouse game that may well have
played its final leg at the Ongnyeon Shooting Range here.
The
yardstick China has played a pivotal role in shaping Bindra’s career. Much of
his achievements have been measured vis-a-vis his Chinese counterparts. So it
was fitting in a way that at his last Asian Games, Bindra was pitted against
two Chinese rivals to battle for that elusive Asiad gold. In his previous
attempts, even an Asiad medal (in individuals) had eluded the 31-year-old. In
that respect, he partially succeeded on Tuesday. Bindra achieved bronze in the
individual and team events (with Sanjeev Rajput and Ravi Kumar). But a gold
continued to dodge him. And once again, the Chinese shooters halted his march.
Bindra, though, wasn’t disappointed. Far from it, in fact. In the presser, he
spoke of the impact Chinese shooters have had on him and his other teammates.
‘We’ve really looked up to them. I’ve enjoyed watching their unbelievable
shots,’ he said. ‘You know, they’ve got guys who’re just 18 and already
shooting incredible scores. I am almost double his age, with grey hair and all.
So I am just happy that I still am capable of finishing on the podium alongside
these young shooters.’ Bindra pointed at Yan Haoran, the ‘child genius’ who has
taken the shooting fraternity by storm. Haoran and his compatriot Yifei Cao
finished above the Indian marksman on the podium. But even before the medal
ceremony could begin, Cao enquired, ‘Will he (Bindra) be continuing?’ It was a
question that only Bindra could answer. Or so we assumed. ‘I know it’s
confusing. But you’ll get it in a couple of days,’ he later said. ‘Look at all
these Chinese shooters, they train 50 hours a week. I did that for 20 years. I
trained 40-50
