Though both gingivitis and periodontitis are diseases of the gums, the related ailments are not simply different severities of the same disease, finds a new study published in Applied and Environmental Microbiology. Researchers confirmed this by investigating the bacterial composition of the sup... Read More
Robots help sort patient samples, test clinical specimens, and analyze the results. Now a study shows that robots, in the form of drones, can help move our samples from place to place, with little effect on the analytical outcome.
Drone transport made a news splash when Amazon proposed using ... Read More

In 2009, fish in Israel began dying in droves. And not just any fish, but the St. Peter’s fish, tilapia in the Sea of Galilee—the fish famed in the Bible for feeding the multitudes and paying the temple tax for St. Peter.
As head of the fish disease laboratory for Israel’s Ministry of Agricul... Read More

The TWiV academia discuss induction of diarrhea by the capsid protein of an astrovirus, and association of a fungal RNA virus with white-nose syndrome of North American bats.
How is it that we are we able to devote so little of our personal time and energy to producing or acquiring the healthy, safe food that we consume multiple times every day? A large part of the reason we seldom worry about agricultural output is that most of us benefit enormously from modernized,... Read More
From archaeal viruses to zoonotic diseases, the breadth of microbiology stories covered on mBiosphere in 2016 was impressive. Here are some of the best posts on mBiosphere from throughout this past year:

H.P. Lovecraft fan and composer Reber Clark (https://reberclark.bandcamp.com/) collaborated with my undergraduate student Ruth Isenberg and myself on a science+music+HPL video. When a log phase culture of Photobacterium leignothi is poured into a Petri dish, and 10 second exposures are taken ev... Read More

This past fall, experts gathered at an American Academy of Microbiology Colloquium in Washington, D.C. to discuss an important topic relevant to many parts of society: the microbiology of built environments. A summary of the experts’ answers to important questions surrounding this topic is now a... Read More
Mosquito saliva, which is injected into the host as a mosquito probes for a blood vessel, contains a collection of chemicals which include anticoagulants to prevent blood clotting, vasodilators to keep blood vessels wide, and anesthetics to prevent us from sensing the mosquito. Saliva also conta... Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
The TWiVoids discuss the March for Science, the GOF moratorium, and a classic virology paper on mapping the gene order for vesicular stomatitis virus.
Well you may ask what virus ?
and I tell you West Nile Virus ( but I want to change it to WNV ). Every year when mosquito season arrives it will bring a lot of diseases . one of them is the memory loss. you may ask how does memory loss concern WNV?
Thousands of people are liv... Read More
Many years ago, Homo sapiens mated with Neanderthals. Today a small percentage of our genome remains Neanderthal, and in a study discussed on this episode of the science show This Week in Evolution, we show that some important genes of our innate immune response - the early response against path...
