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 fields of microbial symbiosis and speciation have achieved astonishing advances during the past two decades, yet symbiosis and speciation are not commonly discussed together and can seem to be odd partners in their capacity to operate synergistically in nature. Indeed, microbial symbiosis is... Read More
"Take a listen to four very savvy and plain-talking biologists chatting on their business at an inside-the-academy site called This Week in Microbiology, and more specifically at episode TWiM 32. There host and Columbia U. faculty member Vincent Racaniello and two colleagues talk of arsenic and ... 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
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
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
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
The Micro'be' project by contemporary textile artist and lecturer Donna Franklin, and scientist Gary Cass, explores fashion and technology's newest frontier: garments made from the bacterial fermentation of wine and beer.
The project's eureka moment came about through a vat of Australian red... 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
Large areas of northern Uganda are experiencing an outbreak of nodding syndrome, a mysterious disease that causes young children and adolescents to nod violently when they eat food. The disease, which may be an unusual form of epilepsy, could be linked to the parasitic worm responsible for river... 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
The third annual installment of my virology course at Columbia University, Biology W3310, has begun, and all the lectures will be available online. 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
Computer-designed proteins are under construction to fight the flu. Researchers are demonstrating that proteins found in nature, but that do not normally bind the flu, can be engineered to act as broad-spectrum antiviral agents against a variety of flu virus strains, including H1N1 pandemic infl...

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
Alien hunters take note: a global water ocean potentially bigger than all those on Earth combined, is sloshing beneath Titan's icy crust.
Combined with the cocktail of organic chemicals already known to exist on Titan, abundant water could make the moon prime real estate for life – though mor... Read More
Pirates used to say that “dead men tell no tales.” Of course, the buccaneers had never heard of the polymerase chain reaction. Dead men turn out to be loaded with information if you can get your hands on them — or better yet, on small preserved pieces.
The genomics revolution, two decades old... Read More
Radio Mycelium proposes the construction of a series of experimental situations examining a new networked imaginary, the single organism of the fungal mycelium, in relation to pathogenic, electromagnetic communications. Participants will learn how to construct simple measurement devices, and cul... Read More
There may be a new wave of computer technology on the way thanks to scientists at the University of Leeds and Japan’s University of Agriculture and Technology: Growing your own computer.
Magnet-making bacteria may be used to create the next generation of hard drives, making them much smaller ... Read More
