Should scientific journals publish gain-of-function (GOF) studies, especially those involving pathogens with pandemic potential? While journal editors at the American Society for Microbiology have done so after careful consideration, some scientists expressed concern over that decision. A series... Read More
Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... Read More

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

Dear TWIM hosts,
I enjoyed episode 76, "Genetic biopixels and a pathogenic sweet tooth". I really enjoyed hearing about the course that Dr. Schaechter teaches and in particular the work his students did in developing the biosensor. I would like to ... Read More
A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.
The Pasteur Institute filed a so-called 'complaint against X' on Mo... Read More
Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.
C... Read More
Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria, not many different strains, as has been widely believed.
The strain—which causes millions of urinary, kidney and bloodstream infections a year—could have a far gr... Read More
Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis - an inflammation and ulceration of the cornea that can lead to loss of vision. The use of contact lenses has been identified as a particular risk factor for microbial kerati... Read More
The Grand Masters of the TWiV discuss Ebola virus transmission, air travel from West Africa, Ebola virus infectivity on surfaces, the Dallas Ebola virus patient, and Ebola virus in dogs.

New videos of morphing bacteria reveal that the strange, distinguishing features of so-called “electric bacteria” aren’t quite what they at first appeared to be.
For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric... Read More
Hello Twim team,
After reading the Pasteur lecture.
The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.
The researchers used a species of malaria parasite that affects rodents, Plasmodium yoelii, and the mosquito, Anopheles stephens... Read More
What effect does the varroa mite, and the viruses it transmits, have on bee colonies? To find out, scientists have developed a new computer model to that simulates a honey bee colony over the course of several years.
Shown in the video on this page, the BEEHAVE model was c0-funded by BBSRC and... Read More
