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.

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
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
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
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
It was a brew to rival any in “Macbeth.” The main ingredients were rat brain and a fearsome, carefully cultivated virus.
In his laboratory in Pearl River, N.Y., 20 miles north of Manhattan, Dr. Hilary Koprowski macerated the ingredients in an ordinary kitchen blender one January day in 1948. ... Read More
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
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,...

Despite the desperate need for new antibiotics to combat increasingly deadly resistant bacteria, the U.S. Food and Drug Administration (FDA) has approved only one new systemic antibiotic since the Infectious Diseases Society of America (IDSA) launched its 10 x ’20 Initiative in 2010 — and that d...

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
Of all the things that could be hazardous to your health, would you believe breathing oxygen makes the list?
Our bodies produce toxic chemicals in our cells, called oxidants, which we fight naturally and with foods that contain antioxidants like blueberries and dark chocolate. All forms of li... Read More
In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people.
A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically ... Read More
They sweep. They swab. They sterilize. And still the germs persist.
In U.S. hospitals, an estimated 1 in 20 patients pick up infections they didn't have when they arrived, some caused by dangerous 'superbugs' that are hard to treat.
The rise of these superbugs, along with increased pressur... Read More
Reconfiguring the genetics of the food pathogen E. coli produces hydrocarbons indistinguishable from those burned in trucks. Welding bits and pieces from various microbes and the camphor tree into the genetic code of Escherichia coli has allowed scientists to convince the stomach bug to produce... Read More
Researchers have found a strain of bacteria that can infect mosquitoes and make them resistant to the malaria parasite. The study, in the journal Science, showed the parasite struggled to survive in infected mosquitoes. Malaria is spread between people by the insects so it is hoped that giving m... Read More
