From Science Daily:

ScienceDaily (Aug. 12, 2009) — A new experimental treatment for multiple sclerosis (MS) completely reverses the devastating autoimmune disorder in mice, and might work exactly the same way in humans, say researchers at the Jewish General Hospital Lady Davis Institute for Medical Research and McGill University in Montreal.

MS is an autoimmune disease in which the body's own immune response attacks the central nervous system, almost as if the body had become allergic to itself, leading to progressive physical and cognitive disability.

Invisible Doorways Or Portals A Step Closer To Reality, Claim Scientists

Scientists close to inventing a Harry Potter Platform 9 and 3/4

From The Telegraph:

Invisible gateways like the one to platform 9 and 3/4 in Harry Potter and to Lewis Carroll's hidden world in Through the Looking Glass are a step closer to reality after scientists developed a new theory.

Using a technique known as transformation optics, the researchers have revealed a way to alter the pathway of light waves that could eventually allow them to create portals that are invisible to the human eye.

Pushing the laws of refraction and reflection to the limit, the team from Hong Kong University and Fudan University in Shanghai, describe the concept of a “a gateway that can block electromagnetic waves but that allows the passage of other entities”.

Antibodies To Strep Throat Bacteria Linked To Obsessive Compulsive Disorder In Mice

from :ScienceDaily

A new study by researchers at Columbia University Mailman School of Public Health's Center for Infection and Immunity indicates that pediatric obsessive-compulsive disorder (OCD), Tourette syndrome and/or tic disorder may develop from an inappropriate immune response to the bacteria causing common throat infections.





The mouse model findings, published online by Nature Publishing Group in this week's Molecular Psychiatry, support the view that this condition is a distinct disorder, and represent a key advance in tracing the path leading from an ordinary infection in childhood to the surfacing of a psychiatric syndrome. The research provides new insights into identifying children at risk for autoimmune brain disorders and suggests potential avenues for treatment.
OCD and tic disorders affect a significant portion of the population. More than 25% of adults and over 3% of children manifest some features of these disorders. Until now, scientists have been unable to convincingly document the association between the appearance of antibodies directed against Group A beta-hemolytic streptoccoccus (GABHS) in peripheral blood and the onset of the behavioral and motor aspects of the disorder. As a result, treatment strategies were restricted to targeting symptoms rather than causes.

'Many Hurricanes' In Modern Times

From BBC:

Hurricanes in the Atlantic are more frequent than at any time in the last 1,000 years, according to research just published in the journal Nature.

Scientists examined sediments left by hurricanes that crossed the coast in North America and the Caribbean.

The record suggests modern hurricane activity is unusual - though it might have been even higher 1,000 years ago.

The possible influence of climate change on hurricanes has been a controversial topic for several years.

Study leader Michael Mann from Penn State University believes that while not providing a definitive answer, this work does add a useful piece to the puzzle.

Why Humans Can Talk And Chimps Can't

Nothing to say (IMAGE: Manfred Rutz/Rex Features)

From New Scientist:

A brain region critical to speech and language ballooned after humans split from chimpanzees, a new study finds.

Named after French physician, Pierre Paul Broca, who identified the region in two brain-damaged patients incapable of uttering more than a few words, Broca's area usually occupies a much larger portion of the left half of the human brain than the right.

Because right-handed humans also tend to process language in their left halves – lefties' brain are flip-flopped – some researchers think that lop-sidedness in Broca's area may help explain why humans alone developed language.

Babies' Brains Churning With Activity

Electrodes recorded brain activity while infants grabbed for toys. The same brain area showed activity whether infants grabbed for a toy themselves or watched an adult do the same. Credit: Michael Crabtree.

From Live Science:

The look of amazement in the eyes of an infant suggests the wheels are churning away inside that noggin. New research confirms they are. Scientists have shown that when 9-month-olds watch people reach for objects, the motor region in their brains gets activated, as if the babies were doing the reaching themselves.

The brain ability is likely due to so-called mirror neurons, which fire both when we do an action ourselves, and when we watch others do a similar action. While such neurons have only been directly measured in monkeys, scientists think they exist in adult humans, and now in infants.

Robot Chefs Run a Restaurant

The FuA-Men - Fully Automated raMen restaruant in Nagoya, Japan features a chef and assistant - both fully autonomous robots. The robots perform all of the cooking tasks needed to make eighty bowls per day, serving the customers who come to their small shop.
When asked, customers seem to feel that there is little difference between noodle dishes prepared by real, human chefs, and meals prepared by autonomous robots. For those who appreciate precision in food preparation, you can't beat robot chefs.
"The benefits of using robots as ramen chefs include the accuracy of timing in boiling noodles, precise movements in adding toppings and consistency in the taste and temperature of the soup," said Kenji Nagaya, president of local robot manufacturer Aisei.
The two chefs also work very well together; their movements are perfectly choreographed (see video).

Mars, Methane And Mysteries

From Scientific American:

Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. ESA plans to find out which it is. Either outcome is big news for a planet once thought to be biologically and geologically inactive.

The methane mystery started soon after December 2003, when ESA's Mars Express arrived in orbit around the red planet. As the Planetary Fourier Spectrometer (PFS) began taking data, Vittorio Formisano, Istituto di Fisica dello Spazio Interplanetario CNR, Rome, and the rest of the instrument team saw a puzzling signal. As well as the atmospheric gases they were anticipating, such as carbon monoxide and water vapour, they also saw methane. "Methane was a surprise, we were not expecting that," says Agustin Chicarro, ESA Mars Lead Scientist. The reason is that on Earth much of the methane in our atmosphere is released by evolved life forms, such as cattle digesting food. While there are ways to produce methane without life, such as by volcanic activity, it is the possible biological route that has focused attention on the discovery.

What's Luck Got To Do With It? The Math Of Gambling

From New Scientist:

FIVE years ago, Londoner Ashley Revell sold his house, all his possessions and cashed in his life savings. It raised £76,840. He flew to Las Vegas, headed to the roulette table and put it all on red.

The wheel was spun. The crowd held its breath as the ball slowed, bounced four or five times, and finally settled on number seven. Red seven.

Revell's bet was a straight gamble: double or nothing. But when Edward Thorp, a mathematics student at the Massachussetts Institute of Technology, went to the same casino some 40 years previously, he knew pretty well where the ball was going to land. He walked away with a profit, took it to the racecourse, the basketball court and the stock market, and became a multimillionaire. He wasn't on a lucky streak, he was using his knowledge of mathematics to understand, and beat, the odds.

First Black Holes Born Starving

FROM SCIENCE DAILY

The first black holes in the universe

The simulations were carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, and John Wise, formerly of KIPAC and now of NASA Goddard Space Flight Center.
Several popular theories posit that the first black holes gorged themselves on gas clouds and dust in the early universe, growing into the supersized black holes that lurk in the centers of galaxies today. However, the new results, published in The Astrophysical Journal Letters, point to a much more complex role for the first black holes.
"I'm thrilled that we now can do calculations that start to capture the most relevant physics, and we can show which ideas work and which don't," said Abel. "In the next decade, using calculations like this one, we will settle some of the most important issues related to the role of black holes in the universe."

The Flu Hunters: Racing To Outsmart A Pandemic

Research student Nick Cattle, working in the flu lab at the World Influenza Centre
Philip Hollis for TIME

From Time Magazine:

On April 25, Rod Daniels, the deputy director of the World Influenza Centre in London, was at a meeting in Germany when he received a call from a co-worker: an influenza outbreak had been reported in Mexico and the first samples of the virus were on their way to London for examination. A virologist who has studied flu for more than 30 years, Daniels knew exactly what he was looking for. Influenza A viruses — the type that can cause pandemics — use a protein called hemagglutinin to bind to the cells of their animal hosts. When a virus jumps from animals to humans, its contagiousness is largely determined by what is called the "binding specificity" of this protein. An alpha-2,3 binding specificity means the virus is well suited to the cells in an animal respiratory tract but probably not human cells. An alpha-2,6 binding specificity, on the other hand, means the virus can easily bind to human cells.

Saturn's Rings to Disappear Tuesday

Magnificent blue and gold Saturn is seen in 2007, as one of its moons, Dione, hangs in the distance. A day on Saturn is pretty short, and it just got shorter. The time it takes the beringed behemoth to complete a spin on its axis has just been calculated by astrophysicists at 10 hours, 34 minutes and 13 seconds, more than five minutes shorter than previous estimates.

In a celestial feat any magician would appreciate, Saturn will make its wide but thin ring system disappear from our view Aug. 11.

Saturn's rings, loaded with ice and mud, boulders and tiny moons, is 170,000 miles wide. But the shimmering setup is only about 30 feet thick. The rings harbor 35 trillion-trillion tons of ice, dust and rock, scientists estimate.

The rings shine because they reflect sunlight. But every 15 years, the rings turn edge-on to the sun and reflect almost no sunlight.

Perseid Meteors To Shower Down Late Tuesday, Early Wednesday

From Salt Lake Tribune:

The most-watched meteor shower of the year is coming back late Tuesday and into Wednesday morning, and this year, stargazers may be treated to even more fiery streaks of light zooming across the night sky.

Under the right conditions, observers away from city light pollution are sometimes able to see an average of one and sometimes two Perseid meteors per minute, said Patrick Wiggins, NASA solar system ambassador to Utah.

"But this year," he said, "NASA is predicting the possibility of an enhanced shower Wednesday morning between 2 and 3 a.m."

The more frequent meteor sightings could happen if the Earth passes through what astronomers suspect to be a particularly rich pocket of meteor-producing particles cast off by the shower's parent comet nearly 400 years ago in 1610.

Oldest Known Paralyzed Human Discovered

The remains of the world's oldest known paralyzed human are excavated in Vietnam. Researchers have found that the man suffered from a rare disorder called Klippel-Feil Syndrome, a condition involving congenital fusion of the spine.

From Discovery:

The remains of a man who could be the world's oldest known paralysis victim have been unearthed by Australian bio-archaeologists in northern Vietnam.

Found at the Neolithic cemetery site of Man Bac, some 100 kilometers (62 miles) south of Hanoi, the remains are between 3,500 and 4,000 years old and belong to an adult male who died around age 25.

Called Man Bac Burial 9, or simply M9, the young man suffered from paraplegia or possibly quadriplegia due to a rare disorder called Klippel-Feil Syndrome, a condition involving congenital fusion of the spine.

Why Exercise Won't Make You Thin

Whether because exercise makes us hungry or because we want to reward ourselves, many people eat more — and eat more junk food, like doughnuts — after going to the gym. Ben Bloom / Getty

From Time Magazine:

As I write this, tomorrow is Tuesday, which is a cardio day. I'll spend five minutes warming up on the VersaClimber, a towering machine that requires you to move your arms and legs simultaneously. Then I'll do 30 minutes on a stair mill. On Wednesday a personal trainer will work me like a farm animal for an hour, sometimes to the point that I am dizzy — an abuse for which I pay as much as I spend on groceries in a week. Thursday is "body wedge" class, which involves another exercise contraption, this one a large foam wedge from which I will push myself up in various hateful ways for an hour. Friday will bring a 5.5-mile run, the extra half-mile my grueling expiation of any gastronomical indulgences during the week.
