For what may be the first time, researchers have discovered a virus inside a host with a non-standard nuclear genetic code — one that differs from the standard genetic code that almost all living things use to produce proteins.
“The finding is significant because it shows that these viruses... Read More
The bacteria that cause acne live on everyone’s skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime. What’s the secret?
In a boon for teenagers everywhere, scientists at Washington University School of Medicine in St. Louis, the University of Cal... Read More
The arms race between bacteria and viruses just got a microscopic bit hotter.
The phenomenon, which was published in Nature this week, was discovered by Kimberly Seed and colleagues when they looked at bacteriophages who usually infect and kill the bacterium responsible for cholera Vibrio cho... Read More
What is more commonplace than saying that prokaryotic cells possess a nucleoid? It is implicit in the term prokaryote itself. Still, it was not shown definitively until the 1940s that bacteria and archaea have such differentiated structures made up of condensed DNA. It was the careful work of “b... Read More
Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins th...

Researchers have discovered that the pandemic 2009 H1N1 vaccine can generate antibodies that protect against a variety of flu strains.
The discovery brings scientists closer to designing a “universal” influenza vaccine that reliably induces broadly cross-reactive antibodies at sufficiently hi... Read More
Exposing packaged liquids, fruits and vegetables to an electrical field for just minutes might eliminate all traces of foodborne pathogens on those foods, according to a Purdue University study.
Kevin Keener, a professor of food science, looks for new ways to kill harmful bacteria, such as E.... Read More
A new technique designed to make current antibiotics more effective works by disabling select genes in bacteria.
Described in the journal Nature Biotechnology, the technique systematically identifies genes within E. coli bacteria that inhibit the production of molecules called reactive oxygen... Read More
If you were a science professor, and you received two equally strong applications for the position of laboratory manager, one from a female, one from a male, which one would you pick? The answer may surprise you.
It is well known that women are underrepresented in many fields of science. Whet... Read More
A new study led by researchers from Harvard School of Public Health (HSPH) and the Wellcome Trust Sanger Institute in the UK has, for the first time, used genome sequencing technology to track the changes in a bacterial population following the introduction of a vaccine. The study follows how th... Read More
In a new study, iron-oxidizing microbes give fresh meaning to the phrase "living off the grid," and provide fresh hope as a potential biofuel.
Researchers at the University of Minnesota, St. Paul, have coaxed a species of bacteria into trading their usual diet of partially-oxidized iron for a... Read More
National Institutes of Health (NIH) scientists studying an emerging coronavirus have found that a combination of two licensed antiviral drugs, ribavirin and interferon-alpha 2b, can stop the virus from replicating in laboratory-grown cells. These results suggest that the drug combination could b... Read More
Public health crises of the past decade — such as the 2003 SARS outbreak, which spread to 37 countries and caused about 1,000 deaths, and the 2009 H1N1 flu pandemic that killed about 300,000 people worldwide — have heightened awareness that new viruses or bacteria could spread quickly across the...

Bruce Walker, Professor of Medicine at Harvard Medical School and Director of the Ragon Institute of Massachusetts General Hospital, MIT and Harvard, talks about his article in the July issue of Scientific American magazine called Controlling HIV, about rare individuals who never develop AIDS af...

During my visit to the University of Vermont today I had lunch with seven talented Microbiology Ph.D. students. One of them asked me what was an important quality to have for achieving success in science. I said without hesitation, ‘Be curious’. It’s the answer I always give. Being curious is th... Read More
Multiple RNA sequences can code for the same amino acid, but differences in their respective "optimality" slow or accelerate protein translation. Stanford biologists find optimal and non-optimal codons are consistently associated with specific protein structures, suggesting that they influence t... Read More
Nearly half of the world's population is at risk of infection by the dengue virus, yet there is no specific treatment for the disease. Now a therapy to protect people from the virus could finally be a step closer, thanks to a team at MIT.
In a paper published today in the Proceedings of the N... Read More
In the February issue of New Phytologist, Tulane University biologists examine why leaf-cutting ants target some plants and avoid others, concluding that high levels of friendly fungi in the leaves of some plants protect them from destruction by ants.
Leaf-cutting ants are major defoliators, ... Read More
Despite the pointless political assassinations of vaccine workers or the police officers who guard them in a few deeply troubled areas, enough progress has been made against polio in the past year that health experts are now planning for the grand finale—its complete eradication by 2018. The off... Read More
IDRI (Infectious Disease Research Institute), a Seattle-based non-profit research organization that is a leading developer of adjuvants used in vaccines combating infectious disease, and Medicago Inc.
