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
Breastfeeding until at least nine months of age increases prevalence in the gastrointestinal tract of Lactobacilli and Bifidobacteria, species which are known to contribute to development of a healthy immune system, according to a paper describing the establishment of the intestinal microbiota d...

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... 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

Sherlock Holmes was as much a scientist as a detective. Maybe that’s because his creator, Arthur Conan Doyle, was influenced by a detective of science: Robert Koch, a German doctor who helped prove the existence of germs. In his new book, The Remedy, Thomas Goetz traces connections between the t... Read More
Imagine going to the doctor with an infection and being sent home with a course of drugs. Unknown to your doctor you actually have two infections. If you take the drugs will the other infection go away by itself? What if you take the drugs and the other infection gets worse? This quandary faces ... Read More
Hello Twim team,
After reading the Pasteur lecture.
Bacteria encased in ice can be resuscitated after thousands, perhaps even millions of years. How these hardy bugs manage to survive deep freeze is something of a mystery. If nothing else, the low levels of radiation hitting Earth’s surface should cause any ice-bound bacterium’s DNA to break apa... Read More
The microbes living in the guts of males and females react differently to diet, even when the diets are identical, according to a study by scientists from The University of Texas at Austin and six other institutions published this week in the journal Nature Communications. These results suggest ... Read More
Vincent, Alan, Rich and Kathy discuss how interleukin 10 modulation of Th17 helper cells contributes to alphavirus pathogenesis.
The smallest, most abundant marine microbe, Prochlorococcus, is a photosynthetic bacteria species essential to the marine ecosystem. An estimated billion billion billion of the single-cell creatures live in the oceans, forming the base of the marine food chain and occupying a range of ecological... Read More
Human sweat is actually much dirtier and bacteria-filled than we initially thought. Scientists have found that sweaty hands can reduce the effect that brass objects have of fighting bacteria. Brass objects can be found in hospitals and schools and sweat can fight off its abilities just an hour a... Read More
The burger patty that slides off the plate, the ice cream treat that plops on the picnic table, the hot dog that rolls off the grill – conventional wisdom has it that you have five seconds to pick it up before it is contaminated.
Fact or folklore?
“A dropped item is immediately contaminate... Read More

Health workers have called the Ebola outbreak in West Africa unprecedented, overwhelming and even out of control.
With 844 cases so far, it's the largest and deadliest outbreak since the virus was discovered in 1976. And it doesn't show signs of slowing down. On Tuesday, the World Health Orga... Read More

The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
Like humans, mice start life with sterile lungs that soon get colonized by microbes, which appear to protect the lung tissue from an asthma-like reaction in the presence of dust mites.
Human cells are outnumbered ten-to-one by the microbes that thrive in and on us. Now a study finds that the ... Read More
