A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to pr...

HIV-1, the most common type of the virus that causes AIDS, has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of researchers has designed a way to snip o... Read More
Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.
The plant's longtime sup... Read More
Dear Vincent & Dickson… and Daniel,
I always enjoy listening to TWIP here in Kona, Hawaii.
Our weather today is 79ºF and clear but we have just experienced a record 25-year overnight low of 54ºF,
U.S. researchers have found a link between intestinal bacteria and the effectiveness of the flu vaccine. And the finding could have important implications for how vaccines are given.
Our intestines are full of bacteria; they help us digest our food. But scientists are starting to learn how im... Read More
Rapid detection of antibiotic resistance is vital in assessing the appropriate antibiotic therapy for an infection. Participants will present data on two new inex... 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
A highly anticipated test of an experimental Ebola vaccine will begin this week at the National Institutes of Health, amid mounting anxiety about the spread of the deadly virus in West Africa.
After an expedited review by the U.S. Food and Drug Administration, researchers were given the green... Read More
We can’t see them, but they are all around us. On us. In us. Our personal microbes—not to mention those in the environment around us—have us outnumbered by orders of magnitude, but scientists are only beginning to understand how they influence our health and other aspects of our lives. It’s an i... Read More
This episode: Engineered phages can both kill bacteria and disrupt their communications!
(14.8 MB, 16.2 minutes)
As the world experiences a wakeup call about the rise of drug-resistant infections, a new approach to creating smarter, “programmable” drugs could combat the two major problems with life-saving drugs today.
On the one hand, today’s antibiotics work a little too well. They not only kill infect... Read More
A woman with an incurable cancer is now in remission, thanks, doctors say, to a highly concentrated dose of the measles virus.
For 10 years, Stacy Erholtz, 49, battled multiple myeloma, a deadly cancer of the blood. Doctors at the Mayo Clinic say she had received every type of chemotherapy dr... Read More
Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More
A debilitating, mosquito-borne virus called chikungunya has made its way to North Carolina, health officials say. It's the state's first reported case of the virus.
The patient was likely infected in the Caribbean, according to the Forsyth County Department of Public Health. Chikungunya is prim... Read More
When scientists launch a spacecraft into space, they're also launching thousands of bacteria along with it.
This article was originally published in the January 2015 issue of Popular Science.
To prepare the Curiosity rover for its trip to Mars, NASA scrubbed it with alcohol and baked it at... Read More
Paul Duprex joins the TWiV team to discuss the current moratorium on viral research to alter transmission, range and resistance, infectivity and immunity, and pathogenesis.
Disruptions in the human circadian clock can throw off microbes in the gut, potentially boosting the risk of obesity, a new study suggests.
The results may help explain why shift workers and people who get jet lag by traveling frequently often pack on extra pounds.
"These surprising findin... Read More
Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.
When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More
