At this point, after finding microorganisms that don’t mind extreme temperatures, pressure, aridity and other hardships, we shouldn’t be surprised that bacteria’s dominion over the Earth extends to just about anywhere we look. A new expedition to the Earth’s crust has reached unprecedented depth... Read More
An inexpensive new filtering technology can kill up to 98 percent of disease-causing bacteria in water in just seconds without clogging.
American Chemical Society's (ACS) award-winning podcast series, "Global Challenges/Chemistry Solutions", latest episode focused on development and successfu... Read More
Researcher Jean-Paul Meijnen has 'trained' bacteria to convert all the main sugars in vegetable, fruit and garden waste efficiently into high-quality environmentally friendly products such as bioplastics. He will be defending his doctoral thesis on this topic, which was carried out in the contex... Read More
Scientists are zeroing in on a promising vaccine to treat hepatitis C, an international symposium was told Friday in Montreal.
Three preliminary clinical trials in England are showing that a so-called therapeutic vaccine can boost the immune response in those infected with the hepatitis C vir... Read More
Researchers at Rush University Medical Center in Chicago have discovered a protein produced by HIV that keeps infected cells from signaling the immune system that they are harboring the virus and should be killed. These data, which suggest a new target for HIV drugs, were published online Octobe... Read More

Hi, Vincent and Dick,
Love your podcast, and did not drink from the streams in Switzerland, because of the cows at all altitudes, even though your Giardia-cast only came up upon my return. Read More
Listeria can pose special challenges for artisan cheesemakers. Many make their cheese right on the farm, where the bad bacteria are right outside the cheese room door. And small producers often lack the safety training and resources available at bigger companies.
For example, Sharon McCool g... Read More
The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and "fixing" or storing carbon.
The research, just published in the journal PLoS One, showed that ... Read More
People who contract gastroenteritis by drinking E-coli infested water are at a greater risk of developing high blood pressure, kidney problems and heart disease in later life, says a study.
The findings underline the importance of ensuring safe food and water supply and the need for regular m... Read More
Contrary to long-held beliefs, plants and animals have developed remarkably similar mechanisms for detecting microbial invasions. This holds promise for the future treatment of infectious diseases in humans.
It may have been 1 billion years since plants and animals branched apart on the evolu... Read More
Government experts are urging those eligible for the vaccine to have it otherwise they will remain vulnerable to flu this winter.
Uptake rates so far this season have shown that fewer people are having the jab than last year.
At the end of October, 48 per cent of over 65s had so far accept... Read More
Full day symposium, free to the public, held at Mountcastle Auditorium at Johns Hopkins University. Speakers include Drs. Brendan Cormack, Tom Cebula, Craig Townsend, Cindy Sears, Ying Zhang (all from JHU), Jacques Ravel, Claire Fraser-Liggett, Jim Kaper (IGS & UMSOM), Barak Cohen (Wash U), Dave... Read More
Scientists in Japan and France have identified a bacterium which appears to turn red plant lice green, enabling them to evade predators and thrive on crops.
The discovery has important implications for pest control as these lice, or aphids, are among the most destructive insects in temperate ... Read More
In nature, it's a dog-eat-dog world, even in the realm of bacteria. Competing bacteria use "toxic darts" to disable each other, according to a new study by UC Santa Barbara biologists. Their research is published in the journal Nature.
"The discovery of toxic darts could eventually lead to ne... Read More
An antibiotic is a modern medical treasure with the unique ability to stop infections caused by bacteria. However, the effectiveness of antibiotics is being threatened by their unnecessary over-use for viral (non-bacterial) infections. More than $1.1 billion are spent annually on unnecessary ant...

Federal health experts on Tuesday voted in favor of the first new drug to treat Lupus in over 50 years, setting aside concerns that the experimental therapy does not work in some key patient groups, including African-Americans.
The recommendation from a panel of Food and Drug Administration a... Read More
Scientists at Emory University and the University of St. Andrews have solved the structure of a key protein from Lassa virus, which is endemic to West Africa and can cause a deadly hemorrhagic fever.
The structure reveals how the virus evades its host's immune system, and how it hijacks infec... Read More
Hong Kong scrambled Thursday to contain any outbreak of bird flu but vied to reassure the public after the teeming city recorded its first human case of the illness since 2003.
The government raised its avian influenza alert level to "serious", meaning there is a "high risk" of people contrac... Read More
