Researchers have more questions than answers about the latest bird flu circulating in China, including whether birds are the only reservoir for the virus.
The World Health Organization (WHO) reports that 17 people in China have died of H7N9 infection, and there is no evidence of person-to-per... 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. (TSX: MDG; OTCQX: MDCGF), a biopharmaceutical company focused on developing highly effective an... Read More
A long-forgotten candidate for antiviral therapy is undergoing a renaissance: Since the 1970s, the small molecule CMA has been considered a potent agent against viral infections, yet it was never approved for clinical use. Scientists at the Bonn University Hospital have now deciphered how the mo... Read More
Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed gr... Read More
An outbreak of high-pathogenicity avian influenza H7N7 virus that took place on 255 poultry farms in the Netherlands during 2003 has been used to provide clues about the current avian influenza H7N9 viruses in China. During the Dutch outbreak 453 humans showed symptoms of illness and 89 were con... Read More
In my newest blog post, I discuss how taking a "beginner's mind" approach leads to creativity, real learning, and enthusiasm. I tie together Suzuki's "Beginner's Mind" concept with Elio Schaechter's "Talmudic Questions," and give an example from one of my first seminars. Read More

A key building block in the Schmallenberg virus could be targeted by anti-viral drugs, according to a new study led from the University of Leeds. The disease, which causes birth defects and stillbirths in sheep, goats and cattle, was first discovered in Germany in late 2011 and has already sprea... Read More
A roller derby tournament seems like a brutal research environment: women crash around a rink in short skirts and skates, slamming their shoulders into members of the opposing team so that their own team’s “jammer” can lap them and score. But it’s perfect for researchers investigating how, throu... 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
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
You know you share genes with your biological parents and kids, but what about microbes? A new study finds that families share skin, tongue and gut microbes with each other... and their dogs.
The study shows how the people and pets you live with affect the microscopic bacteria, fungi and othe... 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
18th International Bioinformatics Workshop on Virus Evolution and Molecular Epidemiology
VEME 2013 will be organized August 25th – August 30th, 2013 at the University of Florida in Gainesville, Florida, U.S.A.
The workshop will have the following modules:
• 'Phylogene... Read More
Hepatitis A virus (HAV) is classified as a non-enveloped Picornavirus. That may have to change, or at least be more specific.
Via electron microscopy, this team found a certain percentage of these viruses were enveloped in exosome-sized particles. Up to 4 virions were found inside these membr... Read More
Background on structural analysis of bacterial proteins, from Erec Stebbins, speaker at the 2012 Holiday Lecture "Bacteria's Deadly Design: How Earth's most prevalent life-form uses a microscopic syringe to invade and attack."
Bacteria, viruses and parasites from land animals such as cats, cows and humans are sickening and killing sea mammals. Scientists have been finding a daunting number of land-based pathogens in seals, dolphins, sharks and other ocean dwellers that wash ashore dead or dying, according to an articl... Read More
Radioactive iron may be first fossil imprint of a nearby cosmic explosion. Sediment in a deep-sea core may hold radioactive iron spewed by a distant supernova 2.2 million years ago and preserved in the fossilized remains of iron-loving bacteria. If confirmed, the iron traces would be the first b... 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
Some facts about the toxin that was found in a letter addressed to US senator Roger Wicker. Government officials in Washington have shut down mail delivery to the US Senate after detecting ricin in a letter addressed to Mississippi senator Roger Wicker, a Republican, on 16 April. Here are some f... Read More
