A new federal report blames a combination of problems for a mysterious and dramatic disappearance of U.S. honeybees since 2006.

The intertwined factors cited include a parasitic mite, multiple viruses, bacteria, poor nutrition, genetics, habitat loss and pesticides.

The multiple causes mak... Read More

For the second time in a matter of weeks, a group of researchers reported a link between the food people eat and bacteria in the intestines that can increase the risk of heart attacks.

Two weeks ago, the investigators reported that carnitine, a compound found in red meat, can increase heart d... Read More

It's easy to forget just how far medicine has progressed. While we may worry about the spread of infectious diseases like avian flu or meningitis today, those pathogens have nothing on fearsome pandemics in the distant past like the Plague of Justinian, which killed over 100 million people from ...

To infect its host, the respiratory pathogen Pseudomonas aeruginosa takes an ordinary protein usually involved in making other proteins and adds three small molecules to turn it into a key for gaining access to human cells. In a study to be published May 7 in mBio, the online open-access journal... Read More

Thanks to a rare bacteria that grows only on rocks in the Swiss Alps, researchers at The University of Texas at Austin and the Pasteur Institute in France have been the first to identify how alcohol might affect key brain proteins.

It’s a major step on the road to eventually developing drugs ... Read More

It's a chemical that's been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby's basinet.

But federal health regulators are just now deciding whether triclosan — the germ-killing ingredient fo... Read More

In its native state, according to the CDC, the H5N1 flu virus is highly contagious and is especially deadly to birds. Fortunately, few people have contracted this strain of flu as it's quite deadly in people as well. Luckily, there have been very few cases of transmission of the virus between pe... Read More

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to m... Read More

Bacteria are all over us, inside and out. Jiri Hulcr recently found 1,458 species of bacteria "new to science" in a small sample of human belly buttons. What we know about our little passengers and how they affect our bodies is dwarfed by what we do not. That can be disconcerting to think about,... Read More

Researchers have uncovered details of a mechanism that bacteria use to avoid the effects of antibiotics, which could pave the way for developing new drugs to counteract antibiotic resistance.

The discovery, from researchers at Durham University and the University of Birmingham, gives the firs... Read More

A CNN iReport about an integrative lab series known as the Wolbachia in Nashville includes area high school students from School for Science and Math at Vanderbilt with the purpose of bringing real-world scientific research on microbes into high school biology classes. Angela Eeds, director with... Read More

Early earth had a distinctive aroma. And it wasn't very nice. That's what scientists have now determined, using advanced imaging techniques to examine fossils nearly 1.9 billion years old that were collected from rocks around Lake Superior, Canada.

Their work has revealed spherical and rod-sh... Read More

Bacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to the distribution of wealth in the U.S. economy, according to a new study by researchers at University of California,...

The resistance of bacteria to antibiotics and similar drugs—called antimicrobials—is considered a major public health threat by the Food and Drug Administration (FDA) and its counterparts around the world.

Antibiotics have transformed health care since they were introduced in the 1940s and ha... Read More

Robert Koch is one of the key figures in early bacteriology, helping develop culture techniques (e.g. solid media), critical reasoning (e.g. Koch’s postulates), and disease etiology (e.g. cholera and tuberculosis). He also published the first photomicrographs of bacteria (Figure 1A) in his 1877 ... Read More
