A new study will explore whether living with a dog encourages the growth of positive microorganisms in the human gut—enough to improve physical and mental health in older adults. Read More
Scientists at the University at Buffalo are turning to an old class of antibiotics to fight new superbugs resistant to modern medicine.
A $4.4 million grant from the National Institutes of Health will allow UB researchers to develop new dosing regimens for polymyxin antibiotics.
Developed ... Read More
David writes (re lice and iron):
All I remember that I know is that one time I let my cat endure a heavy flea infestation for an unconscionably long time. I redeemed myself, if at all, by the knowledge that I slept with her a lot, and so endured a share myself (b... Read More
Like a protective tent over a colony of harmful bacteria, biofilms make the treatment of skin infections especially difficult. Microorganisms protected in a biofilm pose a significant health risk due to their antibiotic resistance and recalcitrance to treatment, and biofilm-protected bacteria ac... Read More
Researchers at Harvard and Yale have used some extreme gene-manipulation tools to engineer safety features into designer organisms.
This work goes far beyond traditional genetic engineering, which involves moving a gene from one organism to another. In this case, they're actually rewriting th... Read More
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 UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More
The TWiV team discusses transmission of Ebola virus, and inhibition of Borna disease virus replication by viral DNA in the ground squirrel genome.
I came across this paper and thought it sounded interesting for a discussion on TWiP:
Colonisation resistance in the sand fly gut: Leishmania protects Lutzomyia longipalpis from bacterial infection
Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.

Romance often sparks between colleagues, and scientists are no different. Nature profiles four super-couples who have combined love and the lab.
When physicists Claudia Felser and Stuart Parkin were introduced at a conference on applied magnetics, they felt an immediate attraction. But then, ... Read More

The Global Virus Network (GVN) announced today the launch of a Task Force on HTLV, Human T-Lymphotropic Virus (HTLV), the world's first known human retrovirus and only known leukemia-causing virus. Experts from 11 countries*, led by Dr. Robert Gallo, GVN co-founder and scientific director and di... Read More
The TWiVbolans discuss the finding that human noroviruses, major causes of gastroenteritis, can for the first time be propagated in B cell cultures, with the help of enteric bacteria.

When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.
The study, done by researchers from Wa... Read More
Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters... Read More
