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

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
Hoy en día, en pleno siglo XXI, ¿puede un virus cambiar el mundo?, ¿puede haber una nueva pandemia mundial? En este libro explicaremos qué es un virus y cómo es la vida de un virus dentro de una célula, veremos qué es una pandemia y hablaremos sobre cómo se originan los nuevos virus de la gripe....

The microbes that call the New York City subway system home are mostly harmless, but include samples of disease-causing bacteria that are resistant to drugs — and even DNA fragments associated with anthrax and Bubonic plague — according to a citywide microbiome map published today by Weill Corne...

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 polio eradication and endgame strategic plan announced by the World Health Organization in 2014 includes at least one dose of inactivated poliovirus vaccine (IPV). Since 1988, when WHO announced the polio eradication plan, it had relied exclusively on the use of oral poliovirus vaccine (OPV)... Read More
Recovering viral genomes from ancient specimens can provide information about viral evolution, but not many old nucleic acids have been identified. A study of 700 year old caribou feces reveals that viruses can be protected for long periods of time – under the right conditions. Read More
In February 2014 I wrote about children in California who developed a poliomyelitis-like paralysis, also called acute flaccid paralysis or AFP. However, the cause of this paralysis was not known. The CDC has released its study of these cases and concludes “The etiology of AFP with anterior myeli... Read More
Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.
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
Jason Roberts, a virologist at the Victorian Infectious Disease Reference Laboratory in Melbourne, Australia, creates three-dimensional simulations of viruses showing how the molecules that make up the capsid and genome might move in very short periods of time. I visited Jason in his laboratory ... 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
After absorbing research on manipulation of the human microbiome, the impact of waterway and agricultural microbiomes, antibiotic resistance spread and the potential of stewardship guard against it, and potential antimicrobial therapies of the future, we have yet to cover an important research t...

As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... 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
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...
