"Deer eat everything but barberry, and because they don’t eat barberry, they’re weeding out forests. They’re helping promote the invasiv... Read More

Chemists' Biosensor May Improve Food, Water Safety and Cancer Detection

A nanotechnology-based biosensor being developed by Kansas State University researchers may allow early detection of both cancer cells and pathogens, leading to increased food safety and reduced health risks.

Lateef Syed, doctoral student in chemistry, Hyderabad, India, is developing the bios... Read More

Antibiotics Wrapped in Nanofibers Turn Resistant Disease-Producing Bacteria Into Ghosts

Encapsulating antibiotics inside nanofibers, like a mummy inside a sarcophagus, gives them the amazing ability to destroy drug-resistant bacteria so completely that scientists described the remains as mere "ghosts," according to a report presented on March 29 at the the 241st National Meeting & ...

Blocking carbon dioxide fixation in bacteria increases biofuel production

Reducing the ability of certain bacteria to fix carbon dioxide can greatly increase their production of hydrogen gas that can be used as a biofuel. Researchers from the University of Washington, Seattle, report their findings in the current issue of online journal mBio®.

"Hydrogen gas is a pr... Read More

'Bacterial dirigibles' emerge as next-generation disease fighters

Scientists today reported development of bacteria that serve as mobile pharmaceutical factories, both producing disease-fighting substances and delivering the potentially life-saving cargo to diseased areas of the body. They reported on this new candidate for treating diseases ranging from food ... Read More

Microbial Fuel Cell (video)

Harnessing the power of the Geobacter microbe, the Office of Naval Research has developed a microbial fuel cell that converts decomposed marine organisms into electricity. The device offers a clean, efficient, lightweight and reliable alternative to batteries and other environmentally harmful fu... Read More

Human virus linked to deaths of two endangered mountain gorillas

Human illnesses are being transmitted to critically endangered mountain gorillas, putting these rare animals further at risk, new research shows.

Centuries ago, mountain gorillas (Gorilla beringei beringei) lived in relative isolation and were rarely seen by people. Today, they live in just t... Read More

Can Cavities Be Contagious?

Everyone knows you can catch a cold or the flu. But can you catch a cavity?

Researchers have found that not only is it possible, but it occurs all the time.

While candy and sugar get all the blame, cavities are caused primarily by bacteria that cling to teeth and feast on particles of food... Read More

'Virus-eater' discovered in Antarctic lake

A genomic survey of the microbial life in an Antarctic lake has revealed a new virophage — a virus that attacks viruses. The discovery suggests that these life forms are more common, and have a larger role in the environment, than was once thought. An Australian research team found the virophage... Read More

Marine microbes digest plastic

Specialist bacteria seem to be eating the plastic garbage we throw into the ocean. But whether they're cleaning up our poisons or just passing them back up the food chain remains to be seen. The ocean contains vast amounts of plastic, mostly as tiny shards floating just beneath the surface. Unde... Read More

AAP Recommends Reducing Rabies Vaccine Dose

Rabies is a virus commonly found in wild animals in the U.S., especially in bats, raccoons, skunks, coyotes and foxes. The virus can be transmitted in the saliva of a rabid animal to a person through a bite or open wound. Read More

Postage Stamps Delivered Anthrax Suspect to FBI

It was the biggest manhunt in FBI history. So it’s not surprising that investigators took all kinds of extraordinary measures to try to figure out who mailed the anthrax-filled letters that killed five people, scared the country half to death, and have jumped back into public consciousness, than...

How Do Plants Fight Disease?

How exactly bacterial pathogens cause diseases in plants remains a mystery and continues to frustrate scientists working to solve this problem. Now Wenbo Ma, a young plant pathologist at the University of California, Riverside, has performed research on the soybean plant in the lab that makes ma... Read More

Blocking Ship-Borne Bioinvaders Before They Dock

The global economy depends on marine transportation. But in addition to cargo, the world's 50,000-plus commercial ships carry tiny stowaways that can cause huge problems for the environment and economy. A new model created by Smithsonian scientists will facilitate accurate screening of vessels f... Read More

FOR KIDS: When bacteria are flu fighters

Not all germs are created equal. Some invade the body and cause disease or harmful infections but others live peacefully in your intestines, helping your body run smoothly. Antibiotics can't tell the difference. They knock out good and harmful bacteria alike.
