Pharm Pollution
Antibiotics in sewage sludge and manure have the potential to poison plants or end up in food.
- Health & Medicine
Survivors’ Benefit?
Smallpox outbreaks throughout history may have endowed some people with genetic mutations that make them resistant to the AIDS virus.
- Anthropology
Cultures of Reason
East Asian and Western cultures may encourage fundamentally different reasoning styles, rather than build on universal processes often deemed necessary for thinking.
- Tech
Building a Supermodel
Researchers are combining ergonomics and biological research with computer power to build a virtual human that can simulate human biology from anatomy down to the genetic code.
-
Evolutionary Shocker?
A specific protein may help plants and animals store genetic variation and release it at times of stress.
-
Numbers in Mind
Initial reports of babies' basic counting abilities have inspired a wave of new research and a spirited debate about what infants really know about numbers.
- Earth
The Importance of Being Electric
By coordinating measurements from telescopes, planes, balloons, and a battery of instruments, terrestrial and space scientists have now placed themselves on almost intimate terms with sprites—luminous shapes that fleetingly appear high above lightning storms.
- Health & Medicine
Boning Up
Biologists have discovered a mechanism for communication between two types of bone cell, and they're exploring the possible bone-growth-stimulating effect of popular cholesterol-lowering drugs called statins.
- Earth
Presto, Change-o!
Compared with the snail's-pace processes that normally shape Earth's surface, the impacts of extraterrestrial objects change our planet's geology in a flash.

Standing Up to Gravity
Studies in space can help physicians better understand a disorder in which patients get faint or dizzy while standing.
- Astronomy
A Dark View of the Universe
Two new studies suggest that galaxies may be surrounded by vast halos of dark matter extending at least 1.5 million light-years from each galaxy's center.
- Physics
Catch a Wave
Detection of gravitational waves predicted by Einstein's 1916 general theory of relativity may finally occur, thanks to a new generation of laser-based observatories.
