Drawing Nanoscale Features The Fast And Easy Way
Scientists have developed a new technique for nanolithography that is extremely fast and can be used in liquids and outside of a vacuum. The technique could help make the manufacturing of nanocircuits commercially viable. Fact or Fiction?: An Opera Singer's Piercing Voice Can Shatter Glass
This article explores the physics that "suggests that a voice should be able to break glass,"looking at the structure of glass, sound volume, and singers who have tried to break a glass. Includes a link to a related article about why an opera singer can be heard over a much louder orchestra. From the website for Scientific American magazine. Pyridine joins the supersonic set
The pyridine chemical group, basically a benzene ring in which one of the six carbons and its attendant hydrogen atom have been swapped for a nitrogen atom, is one of the building blocks of a vast number of biological molecules and is a crucial component in the functionality of an almost as expansive selection of [...] [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." The Hitchhiker's Guide To Altruism: Study Explains How Costly Traits E
Darwin explained how beneficial traits accumulate in natural populations, but how do costly traits evolve? A new study by researchers from Oxford University and the University of Edinburgh explains how kin selection can be seen as a special form of genetic hitchhiking. The Oil Sands Environmental Research Network (OSERN): Frequently Asked
Questions and answers about obtaining petroleum from the "naturally occurring deposits of bituminous sand"(known as oil sand or tar sand) found near the Athabasca River in Canada. Includes information about mining, the kinds of environmental disturbance oil sands mining causes, and reclamation. Also includes maps and a link to a glossary of oil sands acronyms. From the University of Alberta. Infection Puts Extremely Low Birth Weight Infants At Risk For Developm
Extremely low birth weight infants--the tiniest category of premature infants--are much more likely to experience developmental impairments if they acquire an infection during the newborn period, according to a study by the Neonatal Research Network of the National Institute of Child Health and Human Development, one of the National Institutes of Health. The developmental impairments were seen regardless of the type of infection--whether it occurred in the brain, blood or intestines. Want the Sith DVD? Go to Usenet
The great granddaddy of file-sharing networks has new traffic -- scads of it -- thanks to its relative anonymity and tools that make searching and downloading fast and easy. By David McCandless. Making Plant Cells Work Like Miniature Factories
Imagine being able to control how and what a plant produces at a cellular level ... tiny factories to produce just about anything.By understanding how metabolism takes place within plant cells, researchers at the US Department of Energy's Ames Laboratory hope to be able to harness and manipulate the chemical reactions to produce different materials -- sustainable alternatives to petroleum sources for chemicals and raw materials for industrial, pharmaceutical and energy uses. How Exercise Lowers Cardiovascular Risk
It's well-known that physical activity can improve cardiovascular health. But it's the impact exercise has on specific known risk factors that accounts for about 60 percent of that improvement, researchers reported.
