Bacteria common to spacecraft may be able to survive the harsh environs of Mars long enough to inadvertently contaminate Mars with terrestrial life according to research published in the April 2010 issue of the journal Applied and Environmental Microbiology.
The search for life on Mars remain... Read More
Carl Zimmer describes how Ed Marcotte at the University of Texas at Austin and his search for therapies that can kill tumors by restricting blood vessel growth found the genes potential new drugs can target in yeast.
"The scientists took advantage of a peculiar feature of our evolutionary hi... Read More
Viruses can be transmitted to completely new host species that they have not previously infected. Usually host defenses stop the infection before any replication and adaptation can take place. On rare occasions, a novel population of viruses arises in the new host. These interspecies infections ... Read More
Elio Schaechter of Small Things Considered ponders a recent discovery that small multicellular animals, members of the Loricifera and metazoa groups, are able to survive in an anoxic environment known as L’Atalante Basin, a brine “lake” at the bottom of the Mediterranean.

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.
The suit, filed Friday in Cuyahoga Cou... Read More
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.
