From The Telegraph:

A smile can be all it takes to make a woman feel good about her appearance, according to a new study.

Scientists found that women who are unhappy with the way they look feel significantly better about themselves after being greeted by a smiling face.

The boost in self esteem has led psychologists to think that for many, confidence in their appearance is all about social acceptance.

At Last! First Real Evidence For A Rocky Exoplanet

From Wired Science:

There’s finally proof that Earth-like planets can exist outside our solar system: Scientists have managed to measure the mass of exoplanet COROT-7b, revealing that it’s the first exoplanet with a confirmed density similar to our own.

“This is a day we’ve been waiting for for a long time,” said exoplanet researcher Sara Seager of the Massachusettes Institute of Technology, who was not involved in the research. “It’s the first definitive rocky world beyond our solar system, and it’s opening a new gate for our research. We’re really, really excited about it.”

Life Was In The Oceans 200m Years Before Oxygen Made Air Fit To Breathe

Life first appeared in our oceans during the Archean eon when the moon was far closer to Earth. The air was too toxic for life on land

From The Daily Mail:

Life existed in the oceans for hundreds of millions of years while the Earth's air was not fit to breathe, research suggested today.

Plant-like bacteria evolved at least 200 million years before oxygen began to build up in the atmosphere, a study has shown.

During this period in its history, known as the Archaean, the Earth was covered by a poisonous smog of methane, ammonia and other toxic gases.

Direct Evidence Of Role Of Sleep In Memory Formation Is Uncovered

For the first time, researchers have pinpointed the mechanism that takes place during sleep that causes learning and memory formation to occur. (Credit: iStockphoto/Mads Abildgaard)

From Science Daily:

ScienceDaily (Sep. 16, 2009) — A Rutgers University, Newark and Collége de France, Paris research team has pinpointed for the first time the mechanism that takes place during sleep that causes learning and memory formation to occur.

It’s been known for more than a century that sleep somehow is important for learning and memory. Sigmund Freud further suspected that what we learned during the day was “rehearsed” by the brain during dreaming, allowing memories to form. And while much recent research has focused on the correlative links between the hippocampus and memory consolidation, what had not been identified was the specific processes that cause long-term memories to form.

British Skeleton Suggests Ancient Murder Mystery

A skeleton from ancient Roman times, found in the buried town of Venta Icenorum in Norfolk, England is buried on its side. Romans laid bodies out properly, however, suggesting this man might have met a murderous end. Credit: University of Nottingham.

From Live Science:

A skeleton found at an ancient Roman site in Britain has researchers wondering if they've stumbled on a murder mystery.

Excavations at the buried town of Venta Icenorum at Caistor St. Edmund in Norfolk, England, found what, for now, archaeologists are terming a "highly unusual" setup.

"This is an abnormal burial," said archaeologist Will Bowden of the University of Nottingham. "The body, which is probably male, was placed in a shallow pit on its side, as opposed to being laid out properly. This is not the care Romans normally accorded to their dead. It could be that the person was murdered or executed, although this is still a matter of speculation."

The skeleton has been removed for further investigation.

House Panel Resists Changes in NASA Space Program

WASHINGTON — Members of a key House committee said Tuesday that they were reluctant to change NASA’s current plans for human spaceflight after the space shuttles are retired from service, beyond giving more money to the agency.

“I think that good public policy argues for setting the bar pretty high against making significant changes in direction at this point,” said Representative Bart Gordon, Democrat of Tennessee, who is chairman of the Committee on Science and Technology. “There would need to be a compelling reason to scrap what we’ve invested our time and money in over these past four years.”

Do Brains Shrink As We Age?

From Live Science:

As we get older, our brains get smaller, or at least that's what many scientists believe. But a new study contradicts this assumption, concluding that when older brains are "healthy" there is little brain deterioration, and that only when people experience cognitive decline do their brains show significant signs of shrinking.

The results suggest that many previous studies may have overestimated how much our brains shrink as we age, possibly because they failed to exclude people who were starting to develop brain diseases, such as dementia, that would lead to brain decay, or atrophy.

Google Book Search: Why It Matters

From Times Online:

European publishers and copyright holders gathered in Brussels on Monday to submit their opinions to a European Commission hearing on the American Google Book Search settlement.

In a nutshell, the situation is this: Google has embarked on a project to digitise hundreds of thousands of out-of-print and out-of-copyright books in the United States.

Some of these works are still technically in copyright, and the Authors Guild and the Association of American Publishers took Google to court. A proposed settlement was reached last year, under which Google will essentially agree to pay royalties to anyone whose book they inadvertently put on line.

The settlement will be ratified in a Manhattan court on October 7 this year, by which time any European reservations will need to be registered.

Improvements to conventional solar cell manufacturing that could significantly increase the efficiency of multicrystalline silicon cells and bring down the cost of solar power by about 20 percent have been announced by startup 1366 Technologies of Lexington, MA.

Such cost reduction would make solar power more competitive with conventional sources of electricity. In sunny environments, this could bring the cost of solar down to about 15 or 16 cents per kilowatt hour, says Craig Lund, 1366 Technologies's director of business development. That's cheaper than some conventional sources of electricity, especially those used during times of peak electricity demand.

It's Raining Less Than Scientists Thought

From Live Science:

Raindrops just broke their own speed record: they can drop faster than anyone thought possible.

Larger drops are speedier than smaller ones because they are heavier and so can more easily overcome air resistance. But there’s a limit to how fast a drop can go, a “terminal velocity” achieved when the downward force of gravity equals the upward drag of the air. Thus, whenever smaller drops are detected apparently beating larger ones in the race to the ground, atmospheric scientists interpret the observations as errors by recording instruments.

When Nano May Not Be Nano

From A Science Centric:

The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health.

However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is.

A new analysis by an international team of researchers from the Centre for the Environmental Implications of NanoTechnology (CEINT), based at Duke University, argues for a new look at the way nanoparticles are selected when studying the potential impacts on human health and the environment. They have found that while many small particles are considered to be 'nano,' these materials often do not meet full definition of having special properties that make them different from conventional materials.
