decodes dolphins’ math skills:
Dolphins
could teach humans a thing or two about finding Nemo. The aquatic mammals may
pinpoint prey hidden in bubbles by using mental math.
 |
| By studying the clicks of Atlantic bottlenose dolphins, researchers have figured out a way to create sonar that sees through bubbles |
By
adjusting the volume of sonar clicks, then processing the incoming echoes,
dolphins might have solved a problem that still stymies man-made sonar: how to
peer through frothy water. Using clicks that mimic an Atlantic bottlenose
dolphin, scientists devised a system that weeds out sound clutter from
underwater bubbles.
“It’s
really ingenious, actually,” says oceanographer Grant Deane of the Scripps
Institution of Oceanography in La Jolla, Calif. “I think it’s very clever work,
and there are a number of significant applications for it.”
Using
something like a fireman’s hose, researchers shot bubbles into a huge water
tank set underground. The bubbles cloaked a submerged target: a steel ball
slightly smaller than a baseball. Then, the researchers sent out short bursts
of sound — the faux dolphin clicks — underwater, collected the echoes, and
processed the data mathematically to figure out the steel ball’s location.
 |
| Dolphins often send out a spray of bubbles to herd their lunch (in this case, sardines). Unlike man-made sonar, dolphins can see through the frothy clouds using echolocation. |
It worked
“brilliantly,” says physicist and engineer Timothy Leighton who led the study,
published online July 12 in the Proceedings of the Royal Society A.
The
findings could improve man-made sonar, allowing mine-hunting submarines to see
more clearly in murky shallow waters.
Normally,
using sonar to locate targets in bubbly water is a bit like driving a car at
night in thick fog, says Leighton, of the University of Southampton in England.
Switching on the headlights doesn’t improve the driver’s vision; fog droplets
just scatter the light.
Similarly,
bubbles scatter sound. But the sound they reflect gets a sonic boost: Bubbles
kick back sonar signals perhaps a million times more powerfully than equally
sized steel balls in water, Leighton says. This peppy bounce back makes it
tricky for sonar to look through foamy waters.
But
scientists have observed dolphins blowing bubble nets — dense clouds of tiny
bubbles — while hunting schools of fish.
“It
seemed strange,” says Leighton. “Either dolphins are blinding their best
sensory apparatus, or they’re doing something we can’t.” Compared to the best
sonar technology, a dolphin’s hardware is less powerful. But dolphins still
outperform their man-made counterparts.

Inflation on Trial:
Ask any
astronomer what inflation is, and you’ll hear about the moment when the
universe’s primordial fireball expanded like a balloon on steroids, smoothing
and flattening its initial wrinkles before it grew into the cosmos seen
today.Now, some physicists are trying to let a little air out of that scenario.
Generally
regarded as one of the most successful theories about the early universe,
inflationary cosmology is not exactly under attack. But a few scientists are
questioning whether it deserves its reputation as completely untouchable.
Inflation may be the best-developed explanation for many features seen in the
modern universe, these researchers say, but it still has problems.
“The
picture doesn’t really hold together,” says Paul Steinhardt, a theoretical
physicist at Princeton University. “Either inflation needs a major overhaul or
we have to think about some other approach to cosmology.”
In a
paper posted online at arXiv.org in April, physicist Robert Brandenberger of
McGill University in Montreal argues that scientists should continue exploring
alternatives to inflation rather than just taking for granted that it’s right.
 |
| In the most well-accepted picture of the early universe, a period of rapid expansion called inflation follows the Big Bang. Inflation explains many cosmic features visible to astronomers today |
One such
alternative, developed over the last decade, holds that the universe may not
have begun with a single Big Bang, but rather experiences cycle after cycle of
contraction and expansion. Another approach posits a world with a collection of
tiny vibrating strings whose movements generate cosmic features currently
explained by inflation.
Within
the next few years, telescopes may collect enough data to distinguish among the
options. Only then, say the inflation agnostics, will the picture hold together
or fall apart.
“We
really don’t know what happened in the early universe,” says Jean-Luc Lehners,
a cosmologist at the Max Planck Institute for Gravitational Physics in Potsdam,
Germany. “We know what the result was, but we don’t know how the universe got
there.”
Those on
both sides of the issue are quick to point out that inflation could turn out to
be right. Inflation, says Andrei Linde of Stanford University, is “the only
presently existing internally consistent theory of the early universe.” Linde
developed some of the first versions of inflation, and thinks those who
question it are either intellectually off-course or led astray by journalists
looking for a story. “It is quite possible that eventually this theory will be
generalized and extended,” he says. “But so far all attempts to replace it by
something better failed.”

Catching a Cancer:
Mentors
at the Rockefeller Institute had warned Peyton Rous not to waste his career
fooling with “the cancer question.” Then he got the bright idea that tumors
might be contagious. Rous extracted part of a sarcoma from a hen, strained out
the cells and injected the remnants into another bird. The second hen also
developed cancer. Something hidden inside the tumor must be causing the cancer.
His culprit: a virus.
 |
| The human papillomavirus (pink and white in this photoillustration) is a known cause of cervical and other cancers. New techniques have energized the search for viruses that can turn good cells malignant |
Rous’
finding was met with such resounding disbelief that he soon abandoned the
entire line of research. He returned to it 20 years later, still on the
unpopular side of scientific opinion. More years passed, until Rous was finally
vindicated with a Nobel Prize “for his discovery of tumor-inducing viruses” —
56 years after he began his work, in 1910.
 |
| Peyton Rous won a Nobel Prize in 1966 for discovering that a cancer in a chicken could be transmitted via a virus |
Viruses
exist at the border between living and nonliving, working their way into tissues
and piggybacking on a cell’s machinery to make copies of themselves. In the
century since Rous’ chicken studies, researchers have uncovered about half a
dozen viruses that, while going about their sole mission of replicating, happen
to trigger cancer. Some cancer viruses bear familiar names like HPV, known to
cause cervical cancer, and hepatitis B and C, which lead to tumors in the
liver. Others aren’t so famous, including Epstein-Barr virus as a cause of
non-Hodgkin lymphoma and two viruses known to cause tumors in people with
severely repressed immune systems. Yet scores of researchers are intrigued by
the possibility of cancer viruses that haven’t yet been discovered.
As of
now, the official figure for the percentage of human cancers caused by viruses
is around 20 percent — but most experts concede that number is largely an
educated guess, accounting for known viruses behaving in predictable ways.
“Thirty years ago, that number would have been 5 percent,” says Robert Garry, a
virologist at Tulane University School of Medicine in New Orleans. “It’s a
moving target. How high is it going to go? We don’t know.”
Soon,
they may. Until recently, virus hunting involved painstaking detective work.
But improvements in molecular technologies have made it easier to search for
and study the behavior of snippets of nonhuman genes woven around otherwise
normal threads of genetic material. In just the last eight years, a human
pathogen discovery project housed at Washington University in St. Louis has
found 40 new viruses. “We are huge walking bags of viruses,” says Eain Murphy,
a virologist at the Cleveland Clinic. “There are so many we don’t even know
what they do.”
Not all
will have a cancer connection. Yet considering the scope of cancer triggers
that remain undiscovered — even in breast cancer, most women have no known risk
factors aside from their age and sex — many researchers expect previously
unknown viruses will be to blame for some cancers, or at least make otherwise
sluggish tumors more aggressive.
Medical
science has already compiled a long list of little-noticed viruses suspected of
contributing to common malignancies, including cancers of the colon, skin,
lungs, breast and brain. Recently, some types of skin cancer, and possibly
other malignancies, have been linked to a powerful group of viruses called
polyomaviruses, which are little more than free-range cancer genes.
New
investigations also stand to finally settle old controversies — such as whether
a virus can cause breast cancer — and ignite fresh ones. Already, some
scientists are speculating whether lung cancer in nonsmokers may have some
viral origin, either through human viruses or infections from animals. “The
next decade promises to be an exciting era for the tumor virology field,”
researchers wrote last year in Cancer Letters.
Yet with
better virus detection also comes a concern. If people are indeed walking bags
of viruses, then every slice of tissue could hold countless false leads. As a
case in point, researchers almost universally mention XMRV, a virus discovered
in 2006 as a possible cause of prostate cancer. Six years and dozens of studies
later, the general conclusion is that XMRV wasn’t inciting human tumor cells,
but was instead a case of laboratory contamination with a rodent virus.

Militant attacks kill 15 in Pakistan

| A bomb exploded at a compound in northwest Pakistan on Saturday |
A bomb
exploded at a compound in northwest Pakistan on Saturday, killing nine people and
wounding 20, local government and intelligence officials said.
The
bombing in the compound, used by a local militia and containing residential
units and an office, occurred near the village of Spin Tal in the Orakzai
tribal region. The Pakistan military has been conducting operations against
militant groups in the area for months.
"We
are not sure if a suicide bomber hit the compound or if some militants were
assembling a bomb and it accidentally went off," a local government
official said, requesting anonymity.
The
wounded were evacuated to a hospital in neighboring Hangu district. A hospital
official told Reuters that several of the wounded were in critical condition.
Several
militant groups are active in Pakistan's northwestern semi-autonomous tribal regions,
near the border with Afghanistan, including the Pakistan Taliban, responsible
for many of the bombings across the country in recent years.
In
southwestern Baluchistan province, militants attacked a coast guard post,
killing six personnel, local officials said.
The
attackers arrived aboard pick-up trucks and motorcycles and fired
rocket-propelled grenades and assault rifles at the post near the Arabian Sea
coastal town of Peshikan in Gwadar district.
Much of
the violence in Baluchistan, Pakistan's biggest but poorest province, has been
blamed on ethnic Baluch separatists, who are fighting a protracted insurgency,
demanding more autonomy and control over natural resources.
Islamist
militants loyal to al Qaeda and the Taliban are also active in the province,
which borders Iran and Afghanistan.

Colorado 'Dark Knight Rises' Shooting Witnesses
 |
| Gunman At Batman Movie Premiere |
Eyewitnesses
and escapees of the theater shooting at a midnight screening of The Dark Knight
Rises in Aurora, Colo., describe mass confusion and then terror and panicked
fleeing.
The
town's police chief, Dan Oates, said that witnesses "tell us [the shooter,
allegedy 24-year-old James Holmes] released some sort of canister. They heard a
hissing sound and some gas emerged and the gunman opened fire."
"I
knew there was an issue -- well it started, there were explosions behind, but I
thought it was just a normal practical joke, fireworks or something, but then I
see people starting to leave the theater, smoke behind me," an eyewitness
told the Associated Press, "For the first few seconds nobody was
panicking, but then everyone started moving toward the exits and we were being
herded to the upper area of the theater."
Donovan
Tate, a theatergoer who escaped with his girlfriend, told the local CBS
affiliate, "There was this one guy on all fours crawling. There was this
girl spitting up blood. There were bullet holes in some people’s backs, in some
people’s arms. There was one guy who was just stripped down to his boxers. It
looked like he had been shot in the back or something."
Benjamin
Fernandez told CBS, "I was with my younger sister and a friend, Mike, and
Sheala. We decided there's something not right going on. And we got up and as
soon as we walked out the door, we saw several police officers with just
different guns, like shotguns. I don't even know, I've never seen cops holding
guns like that.
"We
walked to the left, and we just saw pretty much everything wasn't even under
control at that point," Fernandez continued. "There was just people,
just there was -- I saw a younger girl laying there, like with bullet wounds
just bleeding, and the look in her eyes was like -- I don't know. I've had
family members who have been close to death, I've been there at the hospital,
and she just had that same look. It was scary."
"At
first, I didn't think it was anything serious, I thought it was a joke or part
of the show... he came in, he was five feet away from me, he came in on my
right side, I was in the second row in the very front. He came in and he threw
in the gas can," Jennifer Seeger, another theatergoer, told NBC News.
"And then I knew it was real. And then he shot the ceiling, and right
after he shot the ceiling, he pointed the gun right at me, and at that point, I
dove into the aisle, and I got lucky because he didn't shoot me.
"But
then he started to shoot people behind me, and bullets started falling on my head,
it was like burning my head because it was so fresh," Seeger continued.
"I could smell gunpowder. And at that point he walked up the stairs, and
all you could hear is mass chaos."
Speaking
to ABC affiliate KMGH, Christ Jones said, "We were maybe 20 or 30 minutes
into the movie and all you hear, first you smell smoke, everybody thought it
was fireworks or something like that, and then you just see people dropping and
the gunshots are constant. I heard at least 20 to 30 rounds within that minute
or two."
"I
hit the floor and hid behind the seats in front of me, pulling my wife down to
hide with me," Adam Witt, speaking to CNN, said. "It was the longest
minute of my life. The gunshots just kept coming. I knew it could be over any
second. I knew my wife could be gone any second. It was absolutely surreal. I
felt something hit my left arm, and my first thought was, 'At least it's just
my arm.'"
One of
the 12 victims killed is Jessica Ghawi, an aspiring sportscaster who had just
recently moved from San Antonio to Colorado. Already, the San Antonio media and
friends have started to remember her with news stories and tweets.

Ramdev on Saturday met his aide Balkrishna, who was arrested by the Central
Bureau of Investigation in a fake document case, in a jail in Dehradun, police
sources said.
Ramdev,
who was staging a sit-in in front of the CBI office in Dehradun in protest
against Balkrishna's arrest, left for Suddhowala jail soon after his aide was
remanded to judicial custody by a court.
Earlier,
a CBI court rejected the bail Balkrishna's application and remanded him in
nine-day judicial custody in a fake document case.
Balkrishna
was arrested on Friday after the court issued non bailable warrants against him
after he failed to appear before it. The CBI had on July 10 filed a chargesheet
in a special court here against Balkrishna in the case.

1) Mayor
hopes London torch tour to lift Olympic mood
 |
| Crowds of thousands cheered the Olympic torch relay through London on Saturday |
Crowds of
thousands cheered the Olympic torch relay through London on Saturday on the
final leg of its tour around Britain, generating excitement that organizers
hope will dispel lingering fears about the event's organization and security.
The
relay, which began in London's historic maritime district of Greenwich, drew a
lively crowd as it passed by the myriad curry houses of east London's Brick
Lane, though the ensuing traffic gridlock underlined the challenges of hosting
the Games in one of the world's busiest cities.
Weeks of
rain and logistical problems have prompted a slew of negative headlines in
Britain's famously critical press ahead of the July 27 to August 12 Games, with
organizers struggling to recruit enough private security guards, forcing them
to look to the army for help. Transport and border staff are also expected to
strike soon, causing further headaches.
Still,
that failed to dampen the crowd's enthusiasm.
"It
might be inconvenient for two weeks, but it's such an advertisement for Britain,
for London. We're so excited," said Rebecca Hurley, 46, who was with her
husband and two daughters.
Others
nearby, however, were far from thrilled, highlighting the cynicism with which
some in Britain see the Games.
"I'm
really not interested in sport. It's hyped-up and annoying - two weeks of
hell," said barwoman Sophie Turner, 20.
Her
friend said she was worried about bomb attacks.
More
British army personnel will be drafted in to secure the games than are
currently serving in Afghanistan, partly to make up for the shortfall of
security guards.
The
Olympic torch arrived in London on Friday after touring scores of British
cities, towns and villages, delivered by a Royal Marine Commando who abseiled
from a helicopter into the Tower of London, one of the capital's main tourist
attractions.
In the
coming days, the torch will be carried around London's religious, political and
royal landmarks, culminating in the lighting of the Olympic cauldron in east
London.
"As
it sprints through the city, I know that its radiance will dispel any last
remaining clouds of dampness and anxiety ... and it will spread the crackling
bush fire of Olympic enthusiasm throughout the city," London Mayor Boris
Johnson told reporters, referring to the torch.
2) Indian
woman boxer Mary Kom qualifies for London Olympics

| Five-time world champion M. C. Mary Kom (51kg) |
Five-time
world champion M. C. Mary Kom (51kg) on Friday added another feather to her
already crowded cap by becoming the only Indian woman boxer to qualify for the
London Olympics despite being on the sidelines after losing in the
quarterfinals of the World Championships held in China.
The
29-year-old Manipuri, who would be returning without a medal from the
mega-event for the first time since its inception in 2001, made the cut after
her quarterfinal nemesis Nicola Adams of England defeated Russia's Elena
Savelyeva 11-6 in the semifinals on Friday.
"Olympic
slot confirmed finally! I am so happy," the mother-of-two said. "I
saw the bout. I know the Russian was not very good but I am a bit sad as well
because I won't have a medal around my neck this time," added the reigning
Asian champion.
"Medal
is very important for me. I am happy with the qualification but I am very upset
not to get a medal."
Women's
boxing will make its Olympic debut in London in three weight categories --
51kg, 60kg and 75kg -- and the ongoing world championships are the first and
the only qualifying event for the quadrennial extravaganza.
In Mary
Kom's division, one slot had been taken by China's Asian Games gold-medallist
Ren Cancan, who is in final now.
The other
slot was to be decided between Mary Kom and North Korea's Hye Kim. While Mary
Kom had lost to world number two Adams, Kim had gone down to Savelyeva in the
quarterfinals.
The
winner of the Savelyeva-Adams bout was to decide the second slot for Asia and
luckily for the Indian, the result went her way.

One-Day International, Hambantota
Scorecard
A late
rally from Kumar Sangakkara and Thisara Perera wasn’t enough to help Sri Lanka
overhaul India’s impressive total of 314 for six in the first One-Day
International in Hambantota. That total was built around a second-wicket
partnership of 173 between Virender Sehwag and Virat Kohli.
The pair
came together following the loss of Gautam Gambhir in the third over and scored
at almost a run a ball as they milked the home side’s attack. Sehwag eventually
fell four short of what would have been his 16th ODI century as he was run-out
at the non-striker’s end. Kohli had no such problems and brought up his 12th
century from 106 balls. During the course of the innings, he had equalled
Sachin Tendulkar’s Indian record of five consecutive scores of 50 or more and
he now had his third straight ton against Sri Lanka to boot.
