Amidst the outrage, puzzlement and theories caused by the finding of genetically-modified wheat in an Oregon field, USDA is considering whether to commercialize another dinnertime staple–the potato.
Last month, Idaho-based J.M. Simplot asked the Agriculture Department to grant a deregulated s... Read More
New research shows giant pandas have a stronger immune system than previously known, because the panda immune system develops different antigens depending on where it lives.
This genetic diversity is a natural defense against extinction, because it means a single pathogen cannot wipe out the ... Read More
In managing bloodstream infections, minutes count, and delays in treatment or administering the wrong antibiotic can kill a patient. In mBio today, scientists from bioMérieux, Inc. describe a new method that could cut hours off the time it takes to diagnose blood infections while also eliminatin... Read More
The word 'unnatural' is often used to describe what's considered weird or unusual. But is anything weirder than nature?
Just look at 17-year cicadas, poised to flood the U.S. East Coast after having stayed underground since Bill Clinton was President. And cicadas are just the start: Biology a... Read More
When a new strain of bird flu cropped up in China last winter, the billion-dollar question was whether the deadly virus could transmit between people.

A dedicated website for sharing biology papers before peer review leaves journals divided.
What are biologists so afraid of? Physicists, mathematicians and social scientists routinely post their research to preprint servers such as arXiv.org before publication, yet few life scientists follow ... Read More
How often do you clean your hands? A study at Rhode Island Hospital observed staff on 161,526 occasions to monitor how often they cleaned their hands (ie, hand hygiene) between July 2008 to December 2012 and found that hand hygiene compliance improved from 60 percent to 89 percent. The study is ... Read More
So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can’t replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated th... Read More
WEDNESDAY, Oct. 23 (HealthDay News) -- A 3-year-old Mississippi girl apparently cured of HIV infection by aggressive treatment right after her birth remains free of the virus, her doctors report. Early treatment with a combination of potent antiretroviral drugs appears to have kept the virus fro... Read More
When cells grow and proliferate, they need to produce large amounts of protein. All this protein is made by ribosomes, therefore rapid growth requires many ribosomes. Because ribosomes are expensive machines for the cell, the cell needs to use them efficiently. In a new study, published in PNAS,... Read More
A compound found in soybeans can be used in new treatments to inhibit the deadly HIV infection, scientists claim. Read More
Nguyen Thi Yen rolls up the sleeves of her white lab coat and delicately slips her arms into a box covered by a sheath of mesh netting. Immediately, the feeding frenzy begins.
Hundreds of mosquitoes light on her thin forearms and swarm her manicured fingers. They spit, bite and suck until bec... Read More
Biologists dissected tissue samples from an oarfish carcass found in California and discovered the creature was hosting quite a few parasites.
“Our findings say that these are actually majorly parasitized fish,” says Armand Kuris, professor of zoology at the University of California, Santa Ba... Read More
Italian officials should not go ahead with expensive clinical tests of an unproven stem-cell therapy that has no good scientific basis.
The Italian government is planning to oversee a clinical trial of a controversial stem-cell therapy. There are many reasons for the trial to be stopped — and... Read More
Want to ensure that miracle drugs can no longer perform miracles?
Then do what some physicians and industrial livestock farmers have done for years: Overprescribe antibiotics to people, and use them cavalierly in farm animals to promote growth or prevent infections before they even occur.

The U.S. Food and Drug Administration today approved the first adjuvanted vaccine for the prevention of H5N1 influenza, commonly known as avian or bird flu. The vaccine, Influenza A (H5N1) Virus Monovalent Vaccine, Adjuvanted, is for use in people 18 years of age and older who are at increased r... Read More

Working with a synthetic gene circuit designed to coax bacteria to grow in a predictable ring pattern, Duke University scientists have revealed an underappreciated contributor to natural pattern formation: time.
In a series of experiments published Oct. 8, 2013, in the journal Molecular Syste... Read More
On 4 July, good news arrived in the inbox of Ocorrafoo Cobange, a biologist at the Wassee Institute of Medicine in Asmara. It was the official letter of acceptance for a paper he had submitted 2 months earlier to the Journal of Natural Pharmaceuticals, describing the anticancer properties of a c... Read More
