Many virological techniques are based on the specificity of the antibody-antigen reaction. Examples in our virology toolbox include western blot analysis and ELISA. While very useful, these methods cannot be used to visualize viral proteins in infected cells or tissues. To do that we must turn t... Read More

Bacteria have a way of sticking together. Lynette Cegelski, a Stanford assistant professor of chemistry, wants to unwind the secrets of exactly how they do it, the better to combat bacterial diseases.
Her research efforts just got a big boost – $1.5 million worth. She is one of three Stanford... Read More
New findings by National Institutes of Health scientists could explain how Salmonella bacteria, a common cause of food poisoning, efficiently spread in people. In a study published this week in the Proceedings of the National Academy of Sciences, researchers describe finding a reservoir of rapid... Read More
Throughout human history, plants have been a source of potent medicines, including many cancer drugs discovered over the past few decades. However, it is quite difficult to discover such drugs and obtain them in large quantities from the plants or through chemical synthesis.

Billions of bacteria are hard at work helping "densify" oilsands tailings ponds at mine sites near Fort McMurray, a crucial step in the difficult and lengthy process of separating water from fine particles.
The trouble is many of these bacteria also generate methane, a greenhouse gas associat... Read More
Kathleen Alexander, associate professor of wildlife in Virginia Tech's College of Natural Resources and Environment, has discovered a novel tuberculosis (TB) species in the Mycobacterium tuberculosis complex, a group of pathogens that have adapted by using mammals as hosts. It has been nearly tw... Read More

Amyloid protein structures are best known for the troubles they pose in the brains of Alzheimer's patients. Now researchers are trying to exploit their presence in a very different place - in semen - to find a new way to stop HIV.
Scientists have created a substance that targets amyloid struc... Read More
The rate of tuberculosis infection in the United States has been going down because of prevention and treatment efforts, but the country may now be more susceptible to new nastier drug-resistant form, according to Johns Hopkins researchers.
The researchers used computer modeling to show an in... Read More
First-responders--firefighters, public health workers--know that when emergencies strike, they'll be on the scene. But those on the front lines are also human, and a new study points out that not all are willing to go to work in the event of a severe pandemic.
The study, conducted by research... Read More
Tim Hortons coffee routinely fuels students. But the paper coffee cups themselves might one day provide fuel for their cars.
That’s the research premise of University of Manitoba biosystems engineering Prof. David Levin and microbiology Prof. Richard Sparling. The two are working on a $10.5-m... Read More
A pioneering international program to stop the spread of the mosquito-borne virus dengue fever has been launched in far north Queensland.
An Australian-led team of researchers has been working on the natural control measure for 15 years and now has regulatory approval for trials outside the l... Read More
For some kinds of bacteria, we have reached the end of the line. No new antibiotics have been developed for decades, and some superbugs are now resistant to all those we have. There is no one solution to the problem of antibiotic resistance, but we desperately need new antibiotics.
Far from h... Read More
The Ministry of Public Health has ordered provincial public health offices to monitor the spread of Hand-Foot-Mouth (HFM) disease after over 10,000 patients have been infected so far this year.
