This photo shows a petri dish swabbed with a culture of bioluminescent marine bacteria. The bacteria give off light using a process known as quorum sensing that is controlled by four small RNA molecules within each of them.
When only one bacterium is present it has the ability to produce li... Read More

Efforts to implement a 'top kill,' pumping heavy mud into the broken riser pipe coming from the Deepwater Horizon oil well, are in progress, with hopeful signs. As oil experts continue to work to seal the gushing leak from the Deepwater Horizo... Read More
The Ebola virus first emerged in 1976, striking fear with the uncontrollable bleeding it causes and mortality rates up to 90 percent. Ever since then, scientists have been struggling to find a way to treat the infection or protect against it.
There has been progress, but nothing quite like t... Read More
A one-two punch by a gut parasite and viruses may help explain the mysterious decline in U.S. honeybees seen over the last four years.
Bees infected with both the fungal parasite Nosema ceranae and with any one of a handful of RNA viruses were much more likely to have come from hives on the d... Read More

A serious shortcoming of current influenza virus vaccines is the need to reformulate them every year or two as the virus undergoes antigenic drift. Many virologists have been captivated by the idea of a more universal vaccine that would endure longer, perhaps a decade or more. The identification... Read More
"Tests in four rhesus monkeys showed that seven daily injections cured 100 percent of them. And Geisbert said the researchers gave the monkeys an extremely high dose of Ebola."
The antivirus injections were given within an hour or so after infection. They are testing to see if they can extend... Read More
A team of scientists from government, academia and private industry has developed a novel treatment that protects mice from infection with the bacterium that causes tularemia, a highly infectious disease of rodents, sometimes transmitted to people, and also known as rabbit fever. In additional e... Read More

Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire.
But recently scientists have begun to realize that some of these little ... Read More
For nearly two decades, Public Enemy No. 1 for the food industry and its government regulators has been a virulent strain of E. coli bacteria that has killed hundreds of people, sickened thousands and prompted the recall of millions of pounds of hamburger, spinach and other foods.

Jeffrey Fox of Microbe interviews Jian Ku Shang,materials scientist from the University of Illinois for the May 2010 issue.
The search for factors contributing to obesity has turned inward — all the way to the middle of the gut, where as many as 100 trillion bacteria hang out. The mix of microbes in a given person’s innards may — emphasize “may” — play some role in determining his tendency to put on pounds by governi... Read More
