Just a quick note to say how much I enjoy TWiM, and in particular, how much I enjoyed episode 32 featuring Rosie Redfield. I don't know how you find time to do this, but I'm gl... Read More
The Centers for Disease Control and Prevention has confirmed three mildly ill children with viruses similar to the swine-origin influenza A (H3N2) viruses identified in three other states. These viruses contain the "matrix (M) gene segment" from the 2009 "Swine Flu" pandemic known as H1N1 virus.... Read More
Researchers use stealthy nanoscale particles to infiltrate vaginal mucus and keep herpes at bay in mice.
Tears and a runny nose can be unpleasant on a windy day, but these mucosal secretions play a vital role in protecting the body from viruses and other malicious microbes. Unfortunately, muc... Read More
You’ve probably heard of "chickenpox parties," where parents get unvaccinated kids together (in the home of an infected child) in the hopes they'll catch the disease. They think making their kids suffer through the disease will help them develop stronger immunity than immunization would provide.... Read More
A new electron microscope that works without a lens may create the highest resolution images ever seen.
Transmission electron microscopy (TEM), which looks through an object to see atomic features within it, has been constrained for over 70 years by the relatively poor lenses that are used to... Read More
Other than basic stuff like the Earth rotating around the sun and E=MC2, how much do you know about the universe? Most people would say: not very much. But if you’re a theoretical physicist, you probably know quite a bit more--but still not that much; most of the mysteries of the universe still ... Read More
In a new study, scientists have determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.
In their finding, a team of researchers, led by Dr. Steph... Read More
The results of a recent study characterizing microbial communities in public restrooms may be enough to change the ways of those who don't already wash their hands after using the toilet. The study found that restrooms are dominated by human-associated bacteria--particularly those from the skin,... Read More
After giving pigs a low-dose of antibiotics for just two weeks, researchers detected a drastic rise in the number of E. coli bacteria in the guts of the animals. And those bacteria showed a large jump in resistance to antibiotics.
The particular strain of E. coli detected in the study was not... Read More
Serratia marcescens streaked on a DNA plate and incubated for 48 hours at room temperature. Read More
Bacteria have adapted to live in many niches; from the environmental bacteria that live in the soil and the seas, to the highly specialised intracellular bacteria that rely exclusively on their surrounding host for nutrients. While all bacteria face challenges in adapting their environment to su... Read More
In TWIV 173, you talked about a study on antibody levels to bird flu (H5N1) in various populations, and related this to infections that don't cause serious enough illness to send someone to the hospital, or perhaps to get them teste... Read More
A dairy cow in California is the fourth known American case of mad cow disease, which is caused by prions, infectious agents composed only of protein (the story hit the press the day after my lecture on this type of illness). Unlike viruses, prions have no nucleic acid and no protective coat. Bu... Read More
The mysterious deaths of millions of bats in the United States and Canada over the past several years were caused by a fungus that hitchhiked from Europe, scientists reported Monday.
Experts had suspected that an invasive species was to blame for the die-off from "white nose syndrome." Now th... Read More
There was a lot of interest in in TDR-TB Friday; both the Leonard Lopate Show on WNYC and Science Friday kindly asked me to be on to talk about it.
While I was waiting for the phone link to Science Friday to become live, an alarming bulletin arrived in my email. The early-warning list ProME... Read More
If infants encounter a wide range of bacteria they are less at risk of developing allergic disease later in life. This is the conclusion of research from the University of Copenhagen, which suggests completely new factors in many modern lifestyle diseases.
Oversensitivity diseases, or allergi... Read More
Changes in an overactive immune system can contribute to autism-like behaviors in mice, new research shows.
Scientists at the California Institute of Technology (Caltech) pioneered the study of the link between irregularities in the immune system and neurodevelopmental disorders such as auti... Read More
The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.
The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

Research by University of Tennessee, Knoxville, faculty has discovered that bacteria's move from sea to land may have occurred much later than thought. It also has revealed that the bacteria may be especially useful in bioenergy research.
Igor Jouline, UT-Oak Ridge National Laboratory joint f... Read More
