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
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
Our gut is home to trillions of bacteria, numbering more than the cells in the rest of our body, and these bacteria help us to digest our food, absorb nutrients and strengthen our immune system. This complex bacterial ecosystem, called the gut microbiota, also helps to prevent bad bacteria from ... Read More
Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have identified the structure of a critical RSV component called the fusion glycoprotein.
Respiratory syncytial virus, or RSV, is a respiratory virus that infects th... Read More
Trypanosome Lytic Factor (TLF) has emerged as a novel arm of innate immunity that is only present in humans and select non-human primates. TLF was originally discovered in human blood as a minor form of High-density lipoprotein (HDL), also known as a good cholesterol, that rapidly kills the Afri... Read More
New scientific research published today in the journal PLoS Biology shows that bacteria can evolve resistance more quickly when stronger antibiotics are used.
Researchers from the University of Exeter and Kiel University in Germany treated E. coli with different combinations of antibiotics in... Read More
Two dangerous things together might make a medicine for one of the hardest cancers to treat. In a mouse model of pancreatic cancer, researchers have shown that bacteria can deliver deadly radiation to tumours — exploiting the immune suppression that normally makes the disease so intractable.

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
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
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
Kal Penn has a pretty unusual resume: He has starred in Harold and Kumar, the most successful series of stoner movies made in the past decade; and has served in the White House as the Obama administration's liaison to youth. Now he's hosting a new show, The Big Brain Theory, on the Discovery Cha... Read More
In this blog entry, I discuss how marine microbiology is fascinating to students, as well as the topic leading me (via social media) to other marine microbiologists. One of those marine microbiologists made me a "shrunken coffee cup" (shrunken due to being carried below a kilometer of depth on ... 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,...

Think about the type of animal that would make an ideal host for a virus. It would gather in large dense groups, making it easier for the virus to jump into fresh hosts. It should have a relatively long lifespan, so any single individual has many chances of becoming infected. It would certainly ... Read More
Warnings about the emergence of another influenza virus may elicit scepticism, but we should not be complacent, cautions Peter Horby.
Once again an animal influenza A virus has crossed the species barrier to cause an appreciable number of human cases. Now, two months after the first known hum... Read More
A 65-year-old Frenchman is hospitalized after contracting France's first case of a deadly new respiratory virus related to SARS, and French health authorities said Wednesday they are trying to find anyone who might have been in contact with him to prevent it from spreading.
It's unclear how o... Read More
Amoeba eat bacteria and other human pathogens, engulfing and destroying them – or being destroyed by them, but how these single-cell organisms distinguish and respond successfully to different bacterial classes has been largely unexplained.
In a report in the journal Current Biology, research... Read More
