When a new disease emerges, scientists and physicians hope something that’s already in the medicine cabinet can be used to treat it.
A new study suggests for the novel coronavirus, that may be the case.
Scientists from the U.S. National Institute of Allergy and Infectious Diseases are repo... Read More
The number of confirmed H7N9 bird flu cases in China increased by four to 91 on Friday. Jiangsu province reported one new case, and Zhejiang province reported three, the state-run Shanghai Daily reported today. The number of dead was unchanged at 17.
An increasing focus among public health ... Read More
Dear Vincent and Dickson,
I just heard your most recent TWIP. Please keep these podcasts going! I love listening to your podcasts and hearing your enthusiasm for my favorite biological topic, parasites. Remember that for every fan... Read More
Those who take part in clinical trials often have to do nasty things, from taking new drugs to forgoing sleep. Participants in a trial organised by Stanley Hazen of the Cleveland Clinic, in Ohio, had a decidedly easier task: eating steak. After reading Dr Hazen’s conclusions, though, they may be... Read More
Intestinal dysbiosis may play a role in gastrointestinal (GI) disorders such as necrotizing enterocolitis (NEC) and irritable bowel syndrome (IBS) in children, and prebiotics and probiotics may be efficacious for treating these conditions, according to Philip M. Sherman, MD, professor of pediatr... Read More
A modified strain of Salmonella could be used to efficiently deliver antigens, the key ingredients of vaccines, into human cells, a study suggests.
Salmonella bacteria use nanoscopic needles to inject their own proteins into host cells, enabling them to survive and replicate inside those cell... Read More
Can scientists rid malaria from the Third World by simply feeding algae genetically engineered with a vaccine?
That’s the question biologists at UC San Diego sought to answer after they demonstrated last May that algae can be engineered to produce a vaccine that blocks malaria transmission. I... Read More
New research, just published, details how University of Cincinnati researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources – lakes and rivers – at a significantly higher rate than the currently used filtering...

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
