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.

ScienceDaily (Sep. 16, 2009) — The power of the imagination is well-known: it's no surprise that scary music is scarier with your eyes closed. But now neuroscientist and psychiatrist Prof. Talma Hendler of Tel Aviv University's Functional Brain Center says that this phenomenon may open the door to a new way of treating people with Alzheimer's, Parkinson's and other neurological diseases.

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.

From CNET:

Just because Gordon Bell and Jim Gemmell are way out there on the nerd spectrum, don't ignore what they have to say in their new book, "Total Recall."

The Microsoft researchers obsessively record e-mails, photos, videos, phone calls, health records, financial transactions, Web site visits, and everything else they can in an attempt to electronically compensate for the fallibility of their own biological memories. Before you recoil at the prospect of letting your own life become this digitally augmented, though, consider that it will be whether you want it or not.

House Panel Resists Changes in NASA Space Program

From New York Times:

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.”

KIGALI (AFP) – Titus the Gorilla King, who became the world's most famous mountain gorilla after starring in Dian Fossey's "Gorillas in the Mist" and a BBC documentary, has died in Rwanda at the ripe old age of 35.

The Rwandan and national parks office said the giant old silverback "succumbed to old age" on Monday after falling ill in the past week.

"He has been sick. He's been weakening. It's in the last week that he started going down," Rosette Rugamba, head of the tourism and national parks office told AFP.

The Fastest (And Most Dangerous) Way To Light A Grill

Go from cold to cooking in 30 seconds with a big can of liquid oxygen.

About a year ago, when resident mad scientist Theo Gray pitched me a Gray Matter column on liquid oxygen, an extremely flammable form of the element, he first proposed showing how to use it to light a grill nearly instantaneously. The lawyers, however, suggested we go a more tame route, so instead we showed how you could make a few drops of the hooch yourself.

Congress Faces NASA’s Shaky Future

From Wired Science:

Congress took its first crack at coming up with a plan for NASA in the wake of an independent report that could mean big changes at the agency — or not.

The Augustine committee, as it’s known because of its head, Norm Augustine, sent over a summary of its findings to the Office for Science and Technology Policy last week. It contained five options for human spaceflight — four of them entailing major changes for the Bush-era Constellation program. All of the plans would require upping NASA’s annual budget by $3 billion a year.

Why Does Music Make Us Feel?

Lukasz Laska

From Scientific American:

A new study demonstrates the power of music to alter our emotional perceptions of other people.

As a young man I enjoyed listening to a particular series of French instructional programs. I didn’t understand a word, but was nevertheless enthralled. Was it because the sounds of human speech are thrilling? Not really. Speech sounds alone, stripped of their meaning, don’t inspire. We don’t wake up to alarm clocks blaring German speech. We don’t drive to work listening to native spoken Eskimo, and then switch it to the Bushmen Click station during the commercials. Speech sounds don’t give us the chills, and they don’t make us cry – not even French.
