Walking across the campus of Montana State University here, David Sands, a plant pathologist, says the blanket of snow draped over the mountains around town contains a surprise.
The cause of most of it, he said, is a living organism, a bacterium, called pseudomonas syringae.

A super-germ that’s become a lethal threat to troops in Iraq and Afghanistan may have met its match in a novel technique that kills entire bacterial colonies within hours.
Today’s troops have a 9 in 10 chance of surviving their battle injuries. But wounds and amputation sites leave them vul... Read More
If you follow the science (and probably Sci-Fi) news at all, you’ve probably heard about Craig Venter’s successful creation of the first synthetic organism. Just so we’re all on the same page, the new organism is much like any other bacterium, except it has a custom-made genome with not only ge... Read More
No virus is more feared than Ebola. So scientists were alarmed when a new species of Ebola emerged in Uganda in 2007.
They worried that the Bundibugyo ebolavirus, as it's called after the township in western Uganda where it was discovered, wouldn't be thwarted by the promising experimental v... Read More

Researchers at Nancy University in Lorraine, France have raised concerns that disease will make it impossible to support long-term space travel such as manned missions to Mars. Space travel both weakens the immune system and promotes more virulent growth of bacteria, a potentially deadly combina... Read More
BBSRC-funded researchers at the University of Oxford and Royal Holloway University of London have discovered that the commonly used and naturally occurring bacterial insecticide Bt works best if applied to young plants and is enhanced by the presence of the insect pests.
The research is publi... Read More

Washington, DC artist Michele Banks, aka Artologica, is a painter who, in her own words, "uses an old and often-disrespected medium, watercolor, to create pieces that are anything but old-fashioned." Her works in Makers Market focus on biological and medical themes, particularly the microscopy o... Read More
Dengue fever only seems like a disease that happens in other countries. Key West, Fla., had 27 cases last year, and another last month.
The federal Centers for Disease Control and Prevention offers a look at the first three of these cases in its current Morbidity and Mortality Weekly Report.... Read More
They live in us and on us, helping digest food and keeping acne at bay, and researchers said on Thursday that most of these germs are turning out to be new to science.
The first look at 178 different microbes that live in or on the human body shows that more than 90 percent of their genetic s... Read More
A new report from the Centers for Disease Control and Prevention (CDC) shows that 1 in 8 public swimming pools is in violation of health and safety codes — and that pools at day care centers and children's facilities seem to be the most frequent offenders.
