A cross-cultural study... view more (2002-10-14)

From trees to high-performance ceramics
When a racing driver brakes, the discs and linings become red-hot. These parts are commonly made of carbon-fiber-reinforced carbon and are black at moderate temperatures. Car manufacturers and their suppliers would dearly like to extend the use of these special brake pads and other hard-wearing... view more (2002-07-22)

Underwater Microscope Finds Biological Treasures in the Subtropical Ocean
Scientists towing an underwater digital microscope across the Atlantic have found possible missing links to the global nitrogen cycle, which in turn is linked to ocean productivity.   view more (2006-06-27)

Spring in your step helps avert disastrous stumbles, scientists say
From graceful ballerinas to clumsy-looking birds, everyone occasionally loses their footing. New Harvard University research suggests that it could literally be the spring, or damper, in your step that helps you bounce back from a stumble.   view more (2006-10-11)

Researchers Setting Up Observatories to Examine Arctic Changes from Under the Ice
Researchers from the Woods Hole Oceanographic Institution (WHOI) are venturing this month to the North Pole to deploy instruments that will make year-round observations of the water beneath the Arctic ice cap.   view more (2007-04-17)

Researchers complete seismic borehole in Kentucky
Drilling has been completed on the deepest borehole for seismic instruments in the eastern U.S. The four-inch diameter hole for the Central U.S. Seismic Observatory (CUSSO), located at Sassafras Ridge in Fulton County, Kentucky, reached a depth of 1,948 feet, where bedrock was encountered.   view more (2006-12-14)

Plant diseases threaten chocolate production worldwide
Chocolate lovers, beware. Each year 20 percent of the cacao beans that are used to make chocolate are lost to plant diseases, but even greater losses would occur if important diseases spread.   view more (2006-06-06)

Minority, low-income diabetics least likely to monitor their blood glucose
Black and Hispanic adults with insulin-treated diabetes are less likely than whites to monitor their blood glucose, according to a new study presented at the American Heart Association's 48th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.   view more (2008-03-17)

Perforating aircraft wings with minute holes could make for more efficient flying.
One way to make aeroplanes fly more efficiently is to drill millions of tiny holes in the leading edges of the wings. Like the dimples on a golf ball this has the effect of reducing drag. However, producing these holes on a manufacturing scale is not yet commercially feasible. Researchers at... view more (2002-01-14)

Drink brewed tea to avoid tooth erosion
Today, the average size soft drink is 20 ounces and contains 17 teaspoons of sugar. More startling is that some citric acids found in fruit drinks are more erosive than hydrochloric or sulfuric acid-which is also known as battery acid.   view more (2008-11-26)

The Amazon : wedding in white and black
What happens when two rivers of widely different character meet? In order to answer this question, hydrologists from IRD (Institut de recherché pour le développement) have examined the confluence of the Rivers Negro and Solim'΅es, in Brazil. These two large water courses join just... view more (2000-11-07)

The universe just became a little simpler
Using images from the Hubble Space Telescope, astronomers have concluded that two of the most common types of galaxies in the universe are in reality different versions of the same thing.   In spite of their similar-sounding names, astronomers had long considered "dwarf... view more (2003-06-18)

Scientists Find Bacteria Thriving on a Feast of Seafloor Rock
On the deep ocean floor, microbial life is feeding on fresh volcanic rock and flourishing with greater abundance than even the most optimistic scientists thought possible. According to a study published May 28 in the journal Nature, scientists have found bacteria growing on oceanic crust in... view more (2008-05-29)

Fossils excavated from Bahamian blue hole may give clues of early life
Long before tourists arrived in the Bahamas, ancient visitors took up residence in this archipelago off Florida's coast and left remains offering stark evidence that the arrival of humans can permanently change -- and eliminate -- life on what had been isolated islands, says a University of Florida... view more (2007-12-04)

A stress meter for fault zones
For the first time, scientists from Rice University, the Carnegie Institution of Washington, and the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have measured - in the field rather than in the laboratory - how changes in stress in rocks affect changes in the... view more (2008-07-10)

Leveling the field for babies with persistent pulmonary hypertension
If he can figure out which babies will be born unable to breathe properly, Dr. Stephen M. Black thinks he can help change that.   view more (2006-10-09)

Tiny holes will have huge telecomms impact
Tiny holes just thousandths of a millimetre in size look set to revolutionise the world of telecommunications within the next few years. As internet use grows and businesses and activities like electronic shopping become increasingly international, our need to be able to send vast quantities of... view more (2001-03-12)
