A New York University anthropologist discusses why she has spent the past four years working alongside New York City's garbage men and women
It's a David versus Goliath kind of story, with an ecological twist: In African savannas (regions with both trees and grass), acacia-dwelling ants can repel voracious, tree-eating elephants, according to new research by published online September 2 in Current Biology .
New experimental models based on three-dimensional reconstructions of human skin are helping to reduce chemical testing on live animals, but cannot yet replace animals altogether
The vaccinal eradication of smallpox was a watershed achievement. But with the cessation of regular vaccinations, infection rates from a related poxvirus are increasing in central Africa
Although liver cells created from induced pluripotent stem cells reflect the defects of their source, they may offer a new tool to study inherited disorders
Our sleep patterns, eating habits, body temperature and hormone levels are driven by the rhythmic activity of body's circadian clock. Travel across time zones or shift work can knock those rhythms out of whack, possibly leading to sleep problems, bipolar disorder, metabolic syndrome and even cancer.
Metabolic profiles based on certain molecules in the blood could enable earlier detection of this asymptomatic malignancy
Plant-dwelling insects are in perpetual danger of being accidentally munched on by plant-eating animals. One such insect, the sap-sucking aphid (a common pest in gardens), has an effective escape plan, though: the bugs detect an approaching herbivore's breath and simply drop off the plant before it's eaten.Researchers at the University of Haifa at Oranim, Israel first noticed this phenomenon when they allowed a goat to feed on aphid-infested alfalfa plants—65 percent of the plant pests simultaneously dropped to the ground just before the vegetation was devoured.The team suspected that several cues might have motivated the mass dropping, including the sudden shadow cast by the goat, plant-shaking triggered by the munching marauder and/or the herbivore's exhalations.
A new study finds that the popular microbicidal silver nanomaterial negatively impacts the growth of plants as well as kills the soil microbes that sustain them
The combined effort of more than 50,000 online video game players may help scientists better understand how proteins fold, solving one of biochemistry's greatest conundrums
All (Submerged) Creatures Big and Small: A Census Catalogues the World's Marine Species [Slide Show]
Scientists are creating a massive global database of marine creatures, revealing tremendous biodiversity ranging from the ocean's shallows to its cold, dark depths
Weather or Not?: Last Winter's Record Snow Driven by Short-Term Meteorologic Patterns, Not Long-Term Climate Change
A new study helps to explain how extraordinary snowfalls occur despite global warming
Without modern sanitation, life would be nightmarish—human and animal waste would fester on the streets along with garbage and food scraps, producing a stench so foul that you'd want to keep your windows closed even in the sweltering heat of summer (for the moment, envision lacking the luxury of air conditioning).
Two new studies suggest that the sugar-regulating hormone insulin may play a role in bone health, and implicate the skeleton as a major regulator of energy metabolism
A lot of communication in the animal world occurs via volatile, information-carrying "scent" chemicals, many of which remain to be chemically identified.
Researchers pin down two genes that may be responsible for abnormal neural development in Down's mice embryos. The findings may help identify possible therapeutic strategies to treat cognitive defects in human patients
Paul D. Blanc, a professor of medicine and author of How Everyday Products Make People Sick: Toxins at Home and in the Workplace, discusses how hazardous chemicals in consumer products affect human health
