Laurene Mascola's distinctive voice and laugh has won my heart this month. I found that when TWiM came up for the third time in my playlist the last couple weeks, I kept listening just for a fix. She should be a star.
I'm glad you had a good reaso... 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
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
Vincent meets up with Janet Butel and Rick Lloyd at Baylor College of Medicine to talk about their work on polyomaviruses and virus induced stress.

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
A University of Alberta researcher’s star is rising thanks to her idea to detect deadly pathogens such as E. coli using a paper device only slightly larger than a postage stamp.
Frédérique Deiss, a post-doctoral fellow in the Faculty of Science, is working on ways to help detect food- and wat... Read More
Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever.
With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carri... Read More
Scientists grew Boechera stricta plants in soil inoculated with microbes from natural B. stricta habitats to study the flowering time phenotype.
The technique researchers employed to isolate soil microbes to study their effect on a single plant phenotype can potentially be applied to other st... Read More
When I was nine, biology gave me my first existential crisis. If I am built out of trillions of tiny cells, I worried, what’s to keep me from crumbling into a pile like a dried-out sandcastle? Almost two decades later, as a Ph.D. student in mathematics at the University of California, Davis, I’m... Read More
The safety breach at a government lab that may have exposed 84 workers to live anthrax centered on a pivotal lapse in procedure: researchers working with the bacteria waited 24 hours to be sure they had killed the pathogens, half the time required by a new scientific protocol.
The lab designe... Read More
Vincent speaks with John Coffin about his career studying retroviruses, including working with Howard Temin, endogenous retroviruses, XMRV, chronic fatigue syndrome and prostate cancer, HIV/AIDS, and his interest in growing cranberries.

Vincent visits the University of Georgia where he speaks with Zhen Fu and Biao He about their work on rabies virus and paramyxoviruses.
A diagnostic tool that’s about the size of a credit card has identified a highly prized gut microbe.
The microbe contains interesting genetic sequences, but it has proven challenging to culture in the lab.
Researchers used the device, called SlipChip, to isolate microbes from a patient’s g... Read More
When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?
Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More
Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More

Some Mississippi State University students have discovered – and named – a new life form, a previously unknown organism discovered on campus in a mud puddle last September.
The newly classified organism – Ptolemeba bulliensis, a unicellular microscopic protest – was scooped from a courtyard b... Read More
