A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... Read More
This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More
Scientists from the University of Queensland and a biotechnology company discovered a new class of antibiotics, which is a kind of synthetic sugar. And the new antibiotics can significantly decrease the drug resistance caused by bacteria, and kill them. These new antibiotics can be a powerful dr... Read More
As my Fall semester approaches, I am reflecting on last Fall. I taught a freshman seminar course revolving around symbioses and parasitism, and was fortunate to have many well known scientists be willing to "virtually visit" my class! Here is my report from last year on the great Jack Gilbert.... Read More
This slideshow outlines the work of WHOI scientists Tracy Mincer and Kristen Whalen in the quest to beat antibiotic resistance through bioprospecting in the ocean. Read More
MIT-WHOI Graduate student Kristen Hunter-Cevera describes the challenges and obstacles involved with growing marine microbes (in her case, Synechococcus) in a laboratory setting, and outlines the value of her research in understanding marine biogeochemistry. Read More
Foot-and-mouth disease virus (FMDV) infects cloven-hoofed animals such as cattle, pigs, sheep, goats, and many wild species. The disease caused by this virus is a substantial problem for farmers because infected animals cannot be sold. Transgenic pigs have now been produced which express a short... Read More

Dear Professors of TWiM,
A new drug acts as a roadblock for malaria, curing mice of established infection, according to a study in The Journal of Experimental Medicine. Treatment was not associated with obvious side effects, suggesting that the drug may also be safe and effective in humans. Read More
Looking out of the window isn’t something most office workers would consider a luxury. But then, most people don’t work in a maximum security, biosafety level 4 high-containment research facility, working to protect the UK’s multi-billion pound agricultural industry from dangerous and highly inf...

Although we now understand that viruses are the most abundant organisms on Earth, there are gaps in our knowledge about their distribution in different environments. Results of a new study reveal the diversity and distribution of viruses in Arctic fresh waters. Read More
Patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) showed clinical improvement after extended treatment with the anti-B-cell monoclonal antibody rituximab. This result suggests that in a subset of patients, ME/CFS might be an autoimmune disease. Read More
This episode: More distantly related bacteria can help each other grow (and produce lots of hydrogen) by temporarily fusing with each other!
