This episode: A study of the bacteria-hunting Bdellovibrio life cycle!
A new study concludes that the vast quantity of methane gas that spewed from the BP oil well in the Gulf of Mexico was gobbled up rapidly by bacteria.
About a third of the material that gushed into the ocean from the BP blowout was in gas form, not oil, and the new study is the latest attempt... Read More
Read a piece that detailed the idea that the world could effectively "run out" of antibiotics as "a nightmare scenario".

Here's what she didn't expect on top of all that: sharing a hospita... Read More
A new study of UK tuberculosis (TB) patients has shown that, for those with a certain genetic profile (genotype), supplementation of vitamin D to their standard antibiotic regimen reduces the time needed for TB bacteria to clear from sputum culture by almost a week for the population studied. Th... Read More
Genetic resistance to antibiotics is not the only trick bacteria use to resist eradication - they also have a second defence strategy known as persistence that can kick in.
Researchers reporting in the Journal of Medical Microbiology have now demonstrated for the first time that interplay occ... Read More

Have you ever seen a person with smallpox? We rejoice that probably you haven’t. In 1977 the disease was eradicated. Only two known research collections of smallpox virus remain, in laboratories in Russia and the United States.
This month, the World Health Organization is debating whether to ... Read More
When an antibiotic is consumed, researchers have learned that up to 90% passes through a body without metabolizing. This means the drugs can leave the body almost intact through normal bodily functions.
In the case of agricultural areas, excreted antibiotics can then enter stream and river en... Read More
About one-third of the human population is infected with a parasite called Toxoplasma gondii, but most of them don't know it. Though Toxoplasma causes no symptoms in most people, it can be harmful to individuals with suppressed immune systems, and to fetuses whose mothers become infected during ... Read More
When men learn the HPV vaccine—which protects women from cervical cancer—can prevent anal cancer, they’re more willing to get vaccinated, a new study shows.
Last month the U.S. Food and Drug Administration approved the human papillomavirus (HPV) vaccine, Gardasil, to prevent anal cancer and a... Read More
Disparities in flu vaccination rates based on race, ethnicity, and age grow even larger in years when the vaccine supply is limited or delayed.
A study published in the American Journal of Preventive Medicine found that the gap in seasonal influenza vaccination rates for African Americans, Hi... Read More
As Republicans take control of the US House of Representatives, science could take a hit – despite a new Congressional measure to boost funding.
"There's going to be a big fight," says Michael Lubell of the American Physical Society in Washington DC. "The question is who blinks first."

Researchers have found a new way of testing for tuberculosis that is fast, cheap and widely available: large rats that can smell the bacteria in a sputum sample.
There are expensive and complicated laboratory tests for tuberculosis, and the World Health Organization recently endorsed a new ma... Read More
Maggots. Rotten meat. Pus-oozing sores. Grossed out yet? Probably. The emotion of disgust is universal, strong and easy to invoke. A single disgusting photo is all it takes to make most of us say, "Ick."
And that's for a good reason. Just as fear protects us from a lion that would eat us, "... Read More
