We are not alone—even in our own bodies. The human gut is home to 100 trillion bacteria, which, for millions of years, have co-evolved along with our digestive and immune systems. Most people view bacteria as harmful pathogens that cause infections and disease. Other, more agreeable, microbes (k... Read More
An octopus in miniature is among the hundreds of larvae found in a recent Census of Marine Life survey of the tiniest creatures in the sea. Read More
The use of antibiotics to treat bacterial infections causes a continual and vicious cycle in which antibiotic treatment leads to the emergence and spread of resistant strains, forcing the use of additional drugs leading to further multi-drug resistance.
But what if it doesn't have to be that ... Read More
Heating and squishing microalgae in a pressure-cooker can fast-forward the crude-oil-making process from millennia to minutes.
University of Michigan professors are working to understand and improve this procedure in an effort to speed up development of affordable biofuels that could replace ... Read More
In dark, rich soils on every continent, microbes dealing with the effects of climate change aren't accelerating global warming the way scientists had predicted, a study by researchers at the University of California at Irvine, Colorado State University and Yale University shows.

Late at night on a sultry evening, I watch intently as the predator senses its prey, gathers itself, and strikes. It could be a polecat, or even a mantis - but in fact it's a microbe. The microscopic world of the single, living cell mirrors our own in so many ways: cells are essentially autonomo... Read More
Researchers from NYU Langone Medical Center have discovered and characterized a general mechanism that controls transcription elongation in bacteria. The mechanism, described in the April 23 issue of Science, relies on physical cooperation between a moving ribosome and RNA polymerase (RNAP) that... Read More
South Africa, trying to overcome years of denial and delay in confronting its monumental AIDS crisis, is now in the midst of a feverish buildup of testing, treatment and prevention that United Nations officials say is the largest and fastest expansion of AIDS services ever attempted by any natio...

We typically spend close to 90 percent of our time inside - at school, work and home. While outdoor air quality is very important, so too is the quality of the air we breathe at home and the office. Yet most of us know very little about the condition of our indoor climate. The chemicals ... Read More
COLUMBUS, Ohio – Scientists have combined chemistry and biology research techniques to explain how certain bacteria grow structures on their surfaces that allow them to simultaneously cause illness and protect themselves from the body's defenses.
The researchers are the first to reproduce a s... Read More
Former Browns receiver Joe Jurevicius, who returned to Cleveland in 2006 to try to help his beloved Browns win a Super Bowl, is suing the team, the Cleveland Clinic and two team physicians over a staph infection that most likely has ended his NFL career.

I really enjoyed your podcast about reverse transcription. I was wondering what makes retroviruses like HIV impossible for our bodies fight off. Are there any retroviruses that can be eliminated from the body?
I was browsing on the "Chronic ... Read More
On episode #79 of the podcast This Week in Virology, Vincent and Alan converse about making published science accessible to everyone, global eradication of poliomyelitis, and whether a plant virus c... Read More
Women are putting their health at risk by dabbing on lipstick, moisturiser and mascara from cosmetics tester packs at high street beauty counters.
In a recent study, researchers found that every make-up tester pack they analyzed was contaminated by the e.coli bug.

The Kansas City Health Department is warning the public about a possible outbreak of shigella infections.
Shigella is a highly-contagious bacterial infection spread from person to person, through handshaking, orally, or even through food or water. It is most commonly transmitted among childre... Read More
Under the supervision of a Virginia Tech plant pathologist, a group of high school, undergraduate, and graduate students isolated and characterized a formerly unknown group of bacteria.
The bacteria strain belongs to the plant pathogen species Pseudomonas syringae. One bacterium of this group... Read More
Here's a brief biography on Catharine Conley, NASA's planetary protection officer, that looks at what her job entails:
"Her job is as serious as a NASA post can be. In addition to protecting potential extraterrestrial life and monitoring for contamination on trips back to Earth, the protectio... Read More
A recent paper published in PLoS One looks at the relationship between alcohol consumption and Anopheles gambiae (the primary African malaria vector).
Malaria and alcohol consumption both represent major public health problems. Alcohol consumption is rising in developing countrie... Read More
Packaged fresh-cut grapes are becoming increasingly popular with consumers who like the convenience and health benefits of these ready-to-eat fruits. To keep table grapes fresh and increase shelf life, scientists are seeking advanced techniques that provide healthy, safe alternatives to conventi... Read More
When a person has an infection, they often consider bacteria and viruses as the culprit, but fungi can also infect humans. One type of infectious fungus is Cryptococcus gattii, a relative of Cryptococcus neoformans, an opportunistic pathogen often seen in HIV/AIDS patients and others with a seve... Read More
