A Virginia Tech researcher is working on a device to create biofuels from bird litter - bedding, manure, feathers, spilled feed and everything else on the floor of chicken coops.

Foster Agblevor, associate professor of biological systems engineering, and a team are developing transportable pyrolysis units that will convert the waste into bio-oil by heating the litter until it vaporizes. The vapor is then condensed to produce the bio-oil, and a slow release fertilizer is recovered from the reactor. The gas can then be used to operate the pyrolysis unit, making it a self-sufficient system.

Three value-added products from one device. It can help produce some energy and get rid of pollution.

Ever heard of cynical shyness? Researchers at the Shyness Research Institute in Indiana say this extreme form of shyness is behind the school shootings in the last decade.

Conveniently, it predominantly affects males and can lead to violent behavior.

Presenting at the 115th Annual Convention of the American Psychological Association (APA), psychologist Bernardo Carducci, PhD, and Kristin Terry Nethery, BA, examined the cases involving eight individuals between 1995 and 2004 who had committed shootings at their high schools.

They examined the news accounts of these shootings for personal and social indicators of cynical shyness—lack of empathy, low tolerance for frustration, anger outbursts, social rejection from peers, bad family relations and access to weapons.

Called by some the Blue Eye of Siberia and by others the Sacred Sea, Lake Baikal, at more than 5,000 feet ( 1,620 meters ), is the world’s deepest lake. The lake has many other interesting features also. For example, more than 330 rivers flow in but only the Angara flows out.

Even the potential for oil-related environmental disaster along the Eastern Siberia–Pacific Ocean pipeline was enough to get that project moved farther away from one one of UNESCO's world heritage objects.

What do you do when Mother Nature herself starts leaking the oil?

This five-minute data visualization shows all 27 named storms of the 2005 Atlantic hurricane season, including sea surface temperature, clouds, storm tracks and storm strength.

Orange and red colors represent ocean temperatures at 82 degrees F or higher - the temperature required for hurricanes to form.

All vertebrates use geometric cues like walls and corners to figure out how to go from place to place. Some, like rats and human children, are so influenced by these geometric cues that they often ignore more reliable features such as a distinctive object or colored wall.

This surprising reliance on geometry has led researchers to suggest the existence of a geometric module in the brain. However, since both humans and laboratory animals typically grow up in environments not entirely made up of right angles and straight lines, the prevalent use of geometry could reflect nurture rather than nature.

Sea surface temperatures are one of the key ingredients for tropical cyclone formation and they were warming up in the Gulf of Mexico, Caribbean and eastern Atlantic Ocean by the middle of August. As a result, they helped spawn Hurricane Dean in the central Atlantic, and Tropical Storm Erin in the Gulf of Mexico, both during the week of August 13.

By late June, sea surface temperatures in the Gulf of Mexico were all over 80 degrees Fahrenheit. That's one thing that hurricane forecasters watch for because sea surface temperatures of 80 degrees Fahrenheit or warmer are needed to power tropical depressions into tropical storms and grow them into hurricanes.

These areas or warm sea surface waters (80 degrees F or higher) are depicted in yellow, orange, and red.

Yes, the sun has its own magical tune and if you want to hear it, click below. Even more interesting, the earth dances in rhythm.

David Thomson and Louis Lanzerotti, team members of the HISCALE experiment on board Ulysses, together with colleagues Frank Vernon, Marc Lessard and Lindsay Smith have proven that sounds generated deep inside the Sun cause the Earth to shake and vibrate in sympathy. They show that distinct, isolated tones, predicted to be generated by pressure and gravity waves in the Sun, are present in a wide variety of terrestrial systems.

Using statistical analysis they have discovered the same distinct tones emitted by the Sun in seismic data here on Earth.

Researchers have found native gold, silver and platinum salts in the dust of decayed stumps. A ton of their ashes contains 3 kilograms of silver, nearly 200 milligrams of gold and 5 grams of platinum.

These biogeochemical anomalies in complex ore deposit regions were formed by microbes and trees, which act as "gold-diggers" and draw soluble salts out of the soil and then die off, leaving behind the concentrate with “enormous” precious metals content.

The oxidation zone of some ore bodies is very close to the ground surface, within reach of tree roots. That is why, the researchers believe, the soil contains almost as much noble elements as the ore does. For centuries, trees and microorganisms gradually sucked them out of the depth and laid in the soil.

Researchers have determined that 97.9 percent of all white rice is derived from a mutation (a deletion of DNA) in a single gene originating in the Japonica subspecies of rice.

Their report, published in the journal PloS Genetics, suggests that early farmers favored, bred and spread white rice around the world.

The researchers report that this predominant mutation is also found in the Indica subspecies of white rice. They have found a second independent mutation (a single DNA substitution) in the same gene in several Aus varieties of rice in Bangladesh, accounting for the remaining 2.1 percent of white rice varieties. Neither of these two mutations is found in any wild red rice species.

Exploring life in the North Atlantic Ocean at various depths of 800 to 3,500 metres, a team of 31 scientists are returning from a five-week scientific expedition which has surfaced a wealth of new information and insights, stunning images and marine life specimens, with one species thought to be new to science.

Professor Monty Priede, Director of the University’s highly-acclaimed Oceanlab, along with colleague Dr Nicola King, and students Jessica Craig, Claudia Alt and James Hawkins, are part of the science team on board the ship.

Professor Priede said: “It is like surveying a new continent half way between America and Europe. We can recognise the creatures, but familiar ones are absent and unusual ones are common.
