Beavers don’t brush their teeth, and they don’t drink fluoridated water, but a new study reports beavers do have protection against tooth decay built into the chemical structure of their teeth.
Nearly 200 pilot whales stranded themselves on New Zealand's South Island on Friday, and hordes of rescuers rushed to the remote area in a bid to guide them back to sea.
Humans aren’t the only species to be influenced by spin. Our closest primate relatives are susceptible, too.
A plateau on the Arctic Ocean floor, where thousands of Pacific walrus gather to feed and raise pups, has received new protections from the Obama administration that recognize it as a biological hot spot and mark it off-limits to future oil drilling.
Most of the genetic mutations that cause cancer result from environmental ‘damage’ (for example, through smoking or as a result of over-exposure to sunlight) or from spontaneous errors as cells divide.
Whenever an endangered animal dies at the San Diego Zoo, researchers race out, regardless of the hour, to remove its sperm or eggs, maybe a bit of ear or eyeball, and carefully freeze the cells in liquid nitrogen.
In the social world, people constantly gather information through visual cues that are used to evaluate others and interact. A new study from researchers at the University of Missouri determined that babies can make sense of complex social situations, and that they expect people to behave appropriately.
A vial of rare snake venom refused to give up its secret formula for lethality; its toxins had no effect on the proteins that most venoms target.
Scientists have developed a potential new therapy based on an unlikely model: immune molecules from cows.
The world's mightiest waterway, the Amazon River, is threatened by the most diminutive of foes - a tiny mussel invading from China.
Humans have fewer remnants of viral DNA in their genes compared to other mammals.
For decades, scientists have recognized the upright posture exhibited by chimpanzees, gorillas, and humans as a key feature separating the “great apes” from other primates, but a host of questions about the evolution of that posture — particularly how and when it emerged — have long gone unanswered.
Farmers have long noted a correlation between rainstorms and disease outbreaks among plants. Fungal parasites known as “rust” can grow particularly rampant following rain events, eating away at the leaves of wheat and potentially depleting crop harvests.
A team of international scientists has discovered a new mechanism by which immune cells in the skin function act as the body's 'border control', revealing how these cells sense whether lipid or fat-like molecules might indicate the presence of foreign invaders.
The skull dates from around 55,000 years ago, fitting into the period when scientists had thought the migrants inhabited the area.
Populations of certain types of marine organisms known collectively as the ‘biofouling community’ – tiny creatures that attach themselves to ships’ hulls and rocks – may quadruple within decades, while others may see their numbers reduced by as much as 80 percent, if the world’s oceans continue to become more acidic, according to new research.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
Eerie fluorescent blue patches of water glimmering off Hong Kong's seashore are magnificent, disturbing and potentially toxic.
A miniscule cluster of estrogen-producing nerve cells in the mouse brain exerts highly specific effects on aggressive behavior in both males and females.
Nearly a week after a mysterious gray gunk surfaced on shorelines in the San Francisco Bay Area, the substance has killed more than 200 seabirds.
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Standards proposed by the Agriculture Department aim to reduce rates of salmonella and campylobacter, another pathogen that can cause symptoms similar to salmonella, in chicken parts, ground chicken and ground turkey. The standards would be voluntary but designed to pressure companies to take steps to reduce contamination.
Cambridge scientists have discovered a solution for controlling one of the world’s biggest environmental and ecological pests – the zebra mussel.
The death of 100 birds in the San Francisco Bay Area has baffled wildlife officials who say the feathers of the birds were coated with a mysterious substance that looks and feels like rubber cement.
Wildlife biologists tracking a tumor-causing virus first diagnosed in eastern wild turkeys five years ago have found the virus is far more widespread - but less deadly - than expected.
