This episode: Killing pathogens by attaching magnetotactic bacteria to them and then raising the heat with magnetic fields!
(10.6 MB, 11.6 minutes)
Polio returns to Nigeria, Zika virus spreads in Miami, and virus infection of plants attracts bumblebees for pollination, from the virus gentlepeople at TWiV.
This episode: Bacteria with their own magnetic compass can also clean up and recover toxic but valuable elements!

While our human biochemical reactions are limited, our ingenuity is not, and scientists are able to exploit microbes for our benefit, such as in chemical spills. Using microbes to degrade or sequester toxic molecules is one form of bioremediation, and has many various applications. Famously, sci... Read More
Despite increasing awareness of Klebsiella pneumoniae as a public health risk, there has been relatively little understood about its mechanisms of pathogenesis.
The bacterium, estimated to be the third most common cause of hospital-acquired infections in the United States in a recent study, c... Read More
Not long after the appearance of an outbreak of viral disease, first scientists, and then newswriters, blame it all on mutation of the virus. It happened during the Ebolavirus outbreak in West Africa, and now it’s happening with Zika virus.
The latest example is by parasitologist Peter Hotez,... Read More
Gruesome, ghastly, grisly. These are the words that popped into my head when I googled images of diabetic foot ulcers—one of the most common chronic wounds creating a silent and costly epidemic in healthcare.
Perhaps even more shocking is the mortality rate connected to these open wounds, wh... Read More

This past weekend, I went to visit a friend and meet his twin toddler boys for the first time. Though both boys eagerly ran around the playground we visited, one was just slightly less active. “He has asthma,” his dad explained to me, “but his brother doesn’t.” Why would two boys with the same e...

Death from influenza virus in older people may be primarily caused by a damaging immune response to flu and not by the virus itself, new research suggests.
Ninety percent of the deaths attributed to flu each year worldwide occur in people aged 65 and older. To understand why older adults are ... Read More
Data from several clinical studies in Brazil establish a strong link between infection of pregnant women with Zika virus and a variety of birth defects collectively called congenital Zika syndrome.
In the latest study conducted in Rio de Janeiro, the authors enrolled 88 pregnant women who had... Read More
What kinds of microbes do you associate with hot springs? Maybe microbial mats? Thermus aquaticus and the discovery of Taq polymerase? Archaea, previously (and erroneously) thought to be strict extremophiles? Viruses may not be the first microbial subtype that springs to mind (pun intended) but ... Read More
One of the important tasks of Public Health England’s Mycology Reference Laboratory is to identify any newly emerging fungal pathogens that could become a public health risk. In recent months, the lab had tracked several clusters of Candida auris infections in British hospitals. The multidrug-re... Read More
Things have been quiet on mBiosphere lately. We've been busy updating from ASM Microbe, covering some of the fascinating research presented there. The first Microbe meeting, which combines the former general meeting and ICAAC, was a whirlwind of poster presentations, lectures, seminars, book sig... Read More
Bitter tasting yogurt or cheese may not make it to your refrigerator, but it is produced and the result of pesky bacteria. The microbial composition of raw milk impacts the quality, shelf life, and safety of processed milk and other dairy products. Controlling the quality of these products is tr... Read More
Host: Jeff Fox with special guest, Emma Wilson.
Emma H. Wilson of the University of California, Riverside, talks with Jeff Fox about efforts, with her collaborators to determine more precisely how Toxoplasma gondii parasites disrupt the mammalian brain—in this case, the brains of mice... Read More
Greg Caporaso was sifting through blog posts on microbe.net, which covers the microbiology of built environments, when a study idea sparked for him and colleagues Jeff Siegel, Scott Kelley and Rob Knight.
“It became clear to me that there was a lot of interesting work being done to understand... Read More
The changing weather reminds us that influenza season is around the corner, which means it’s nearly time to get your annual vaccine. This year’s vaccine is updated to protect against influenza A viruses H1N1 + H3N2 and influenza B virus Victoria lineage. These strains are included in vaccine pro... Read More
Biofilms, surface-attached microbial communities encased in an extracellular matrix, are one of the most common macroscopic microbial structures we can see in nature. Biofilms like those seen in pond scum, in dental plaque, or in hot springs, are mixed communities with the members forming both a... Read More
