Experiments led by researchers at the University of California, Berkeley, have demonstrated that normally friendly ants can turn against each other by exploiting the chemical cues they use to distinguish colony-mates from rivals.
The new study, to be published on October 28, in the open-acces... Read More
The emergence of the H1N1 swine flu has added urgency to what has become an annual ritual for millions of Americans: getting a flu shot. The good news is that scientists have developed a vaccine against the H1N1 virus. But it is taking much longer than expected to produce the hundreds of million... Read More
A research team from the Department of Microbiology at the Swedish University of Agricultural Sciences (SLU) has developed a breakthrough vaccine for the highly contagious horse disease strangles, caused by the Streptococcus equi bacterium. The results of the study, published in the journal Publ... Read More
Special genes inserted into crop plants have a way of leaking into the environment. That much scientists know for sure. What they're less certain about is what effect those genes have on plants growing in the wild.
Andrew Stephenson is interested in answering that question. He's a plant ecolo... Read More
Scientists are looking at diverse sources — such as soil and frog skins — for new antibiotics, worried that doctors will run out of options to treat increasingly antibiotic-resistant infections.
Doctors fear they may exhaust their antibiotic treatment options because simple infections could b... Read More
In hopes of preventing the next global pandemic and a possible death toll into the millions, UC Davis today launches an unprecedented international effort to find and control diseases that move between wildlife and people.
The global early warning system, named PREDICT, will be developed with... Read More
"To survive in hostile environments, cockroaches rely on their own vermin: Blattabacterium, a microbe that hitched a ride inside roaches 140 million years ago, and hasn’t left since.
Researchers who sequenced the Blattabacterium genome have found that it converts waste into molecules necessar... Read More

Federal health officials are preparing a plan to study a bold new strategy to stop the spread of the AIDS virus: routinely testing virtually every adult in a community, and promptly treating those found to be infected.
The strategy is called “test and treat,” and officials say the two sites... Read More
Genetically modified squash plants that are resistant to a debilitating viral disease become more vulnerable to a fatal bacterial infection, according to biologists.
"Cultivated squash is susceptible to a variety of viral diseases and that is a major problem for farmers," said Andrew Stephens... Read More
A workshop at the Smithsonian Tropical Research Institute in Panama has dramatically improved the ability of conservationists and regulatory agencies to monitor the spread of chytridiomycosis -- one of the deadliest frog diseases on Earth.
Caused by the chytrid fungus, Batrachochytrium dendro... Read More
With the amount of bottles of alcohol-based hand sanitizer available for public use at hospitals, schools, day-care facilities and malls now outnumbering the billions of viruses and bacteria on even the dirtiest of human hands, you may be wondering if this stuff actually works.
Is it better t... Read More
Animals are now picking up human diseases, possibly as a result of globalisation, a study suggests.
Researchers from the Roslin Institute in Edinburgh said a strain of bacteria had jumped from humans to chickens.
The team believes the Staphylococcus Aureus bacteria crossed between species ... Read More
Guest blogger William C. Summers, Yale University School of Medicine, authors a post at Small Things Considered about the potential for a new rabies vaccine as evidenced in a recent PLoS paper titled "Effective preexposure and postexposure prophylaxis of rabies with a highly attenuated recombina...

Mayo Clinic researchers have found that a sometimes deadly stomach bug, Clostridium difficile, is on the rise in outpatient settings. Clostridium difficile is a serious bacteria that can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. These findings were prese... Read More
The probiotic, Bacillus polyfermenticus, can help mice recover from colitis, a new study has found. Mice treated with B. polyfermenticus during the non-inflammatory period of the disease had reduced rectal bleeding, their tissues were less inflamed and they gained more weight than mice that did ...

Stinking lagoons of pig manure created by thousands of animals in giant hog farms can pollute rivers, poison groundwater and pump out clouds of methane and carbon dioxide. So finding alternative uses for the slurry - to generate electricity, say - makes a lot of sense. The problem was that no on... Read More
