A chemical widely used in soaps, toothpaste, and toys weakens muscles in mice. Triclosan, an antibacterial chemical, hinders muscle contractions at a cellular level, slows swimming in fish, and reduces muscular strength in mice, according to researchers at the University of California, Davis, an...

Dear Vincent,

I am glad you had a chance to get a glimpse of the BSL4 world. You might remember that I have been trying for 1 1/2 years to get you to see the Galveston National Laboratory, a facility with an actual ACTIVE program and a number of... Read More

We often think of the world around us as sterile and static, especially when we are in a hospital. In reality, every surface on earth is literally teeming with millions of bacteria.

Jack Gilbert, a microbiologist from the University of Chicago, has spent his career investigating these invisib... Read More

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study may reshape the universal family tree, adding a fourth major branch to the three that most scientists agree represent ... Read More

I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More

There is a long history of anecdotal evidence to suggest that cranberries and other alternative therapies to long-term antibiotics can prevent recurrent urinary tract infections but are they really as effective as antibiotics or even a viable alternative for people who do not want to take antibi...

The bacterium, Enterococcus faecalis, which lives in the human gut, is just one type of microbe that will be studied as part of NIH's Human Microbiome Project. Read More

A mysterious condition called Inclusion Body Disease (IBD) strikes captive boa constrictors and pythons, causing bizarre behavioral changes and eventually death. Scientists investigating an outbreak of IBD among snakes at the Steinhart Aquarium in San Francisco report they may well have found a ... Read More

Since the introduction of highly active antiretroviral therapy in the mid-1990s, HIV infection has evolved from a near-certain death sentence to a manageable, chronic disease. Still, little is known about the long-term effects of HIV on human health. Two studies being presented today on cardiova... Read More

There is much in the way of microbial activity that is taking place in one of the world’s most poisonous dumps, which turns out to be cleaning up the place.

Take the 150-foot-high garbage dump in Colombia, South America. Soon it may have life as a public park thanks to work from researchers ... Read More

Many species exhibit cooperative survival strategies — for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage of cooperators. This can be seen even among microbes such as yeast, whe... Read More

Simon Fraser University virologist Masahiro Niikura and his doctoral student Nicole Bance are among an international group of scientists that has discovered a new class of molecular compounds capable of killing the influenza virus.

Working on the premise that too much of a good thing can be ... Read More
