Normally, animals get their DNA from their parents. But a new study shows that they can also get genes from another species. In fact, animals can even take genes from creatures outside of the animal kingdom — like from fungi. And that's pretty surprising.
"The idea that animals picked up DNA... Read More

There's no way to stop oily water from reaching land along the Gulf Coast, but experts will use tools both massive and microscopic to clean it up.
Oil-soaked sand on beaches in the eastern Gulf Coast can be scooped up with heavy equipment, but the grassy marshes in the Mississippi Delta can't... Read More
A multimillion-dollar research project involving the University of Nevada, Las Vegas, could help better protect U.S. troops. But it is also expected to shore up the Las Vegas area against epidemics and bioterrorism.
UNLV Associate Professor Chris Cochran is helping lead the effort and hopes i... Read More
The publicity surrounding the pandemic H1N1 influenza virus apparently had a good side effect, the Centers for Disease Control and Prevention reported Thursday. Seasonal flu vaccinations reached 40% of the eligible population this past winter, up from 33% the previous winter, the agency reported... Read More
The molecular caps at the ends of chromosomes that protect humans against cancer and premature cellular aging show a surprising inability to protect themselves against ultraviolet radiation, a new Yale School of Medicine study has found.
Telomeres—the repeat sequences of DNA at the end of chr... Read More
Restricted-calorie diets have been shown in some studies to improve longevity and provide other health benefits, but many studies have focused on animals rather than humans.
A new study finds that calorie restriction may bolster the immune system in adults. Researchers from Tufts University r... Read More

Scientists are turning harmful bacteria into agents of their own destruction. In an effort to create antibacterial wound dressings, a new material comes laden with microbial booby traps that are triggered by the activity of harmful bacteria, scientists report online April 20... Read More
The virus in question is cytomegalovirus, or CMV, which infects most people at some point in their lives -- up to 80 percent of U.S. adults by the age of 40. In healthy people, the infection usually causes no symptoms, and is considered dangerous only for newborns infected during pregnancy and f... Read More
India has exported a polio virus to Tajikistan, re-infecting the region for the first time since it was certified polio-free in 2002.
In what is the first outbreak of the crippling disease in a Central Asian country, the virus till April 22 had caused acute flaccid paralysis (AFP) in 128 chil... Read More
A study published in the journal Science offers a long-awaited explanation for the link between HIV infection and susceptibility to life-threatening nontyphoidal strains of Salmonella. The research, funded by the Wellcome Trust and GlaxoSmithKline, goes on to identify targets that could be pursu... Read More
Melanin-covered nanoparticles provide a novel approach to protection of bone marrow from ionizing radiation based on prevention of free radical formation by melanin, according to research published online April 24 in the International Journal of Radiation Oncology, Biology and Physics.

The Geobacter bacterium could be the biofuel-generating machine of the future, producing energy-rich butanol costing as little as $2 per gallon.
A project seeking to accomplish this, headed by Derek Lovley and colleagues at the University of Massachusetts, Amherst, received $1 million in fund... Read More
Aphids, those sap-sucking foes of gardeners, come in a variety of colours. We usually think of them as green, but pea aphids sometimes wear a fetching red ensemble. That may not strike you as anything special; after all, lots of animals are red. But the aphid’s colour is unique in a couple of ex... Read More
Biologists at the California Institute of Technology (Caltech) have found that an altered host–microbe relationship, called dysbiosis, may be linked to inflammatory bowel disease and colon cancer as well as to obesity and diabetes. Close to a thousand different species of bacteria reside in the ... Read More
Researchers have found a way to modify viruses so they are able to hunt down and wipe out cancer cells.
Scientists at the University of Leeds used unique markers that appear on the surface of cancer cells to engineer proteins that recognize and attach to these markers, that can be added to a ... Read More
Combination antibiotics effectively treat Chlamydia-induced reactive arthritis – a major step toward management, and possibly cure, of this disease, a federal multicenter clinical trial led by the University of South Florida College of Medicine found.
The trial, sponsored by the National Inst... Read More
Life on Mars, if it ever existed, may be easier to find than previously thought. New research on terrestrial rocks suggests that a type of rock common on Mars can preserve fossilized microbial life, rather than erasing evidence of it as previously thought. Read More
A recent paper published in PLoS One looks at the strategy of manipulating surface proteins on the aquatic bacterium, Caulobacter crescentus, to prevent HIV infection.
The development of alternative strategies to prevent HIV infection is a global public health priority. Initial e... Read More
