The U.S. education policy world—the entire country, for that matter—is on a quest to increase the ranks of future innovators in science and technology. Yet the programs that get funded in K–12 education do not support students who are already good at and in love with science. These students have... Read More
The cutting edge of robotics may not be a smarter Siri or a less-creepy humanoid Japanese robot. It might be a swarm of bacteria, compelled to do our bidding through a remotely controlled magnetic field.
Some of the biggest technological advances of the past two decades have involved scaling ... Read More
Cryptococcus gattii, a virulent fungus that has invaded the Pacific Northwest, is highly adaptive and warrants global "public health vigilance," according to a study by an international team of researchers. C. gattii, which likely originated in Brazil, is responsible for dozens of deaths in rece... Read More

The technique addresses the problem of hidden reservoirs of HIV in the body, and could herald a new way of battling the viral infection.
Once HIV invades the body, it doesn’t want to leave. Every strategy that scientists have developed or are developing so far to fight the virus – from powerf... Read More
Scientists at the University of Kentucky, led by nano-biotechnologist Peixuan Guo, have made some critical discoveries over the past year into the operation of biomotors, the molecular machines used by viruses and bacteria in the packaging of DNA.
Biomotors function similarly to mechanical mo... Read More
Signals from the immune system that help repel a common parasite inadvertently can cause a dormant viral infection to become active again, a new study shows.
Further research is necessary to understand the clinical significance of the finding, but researchers at Washington University School o... Read More

The Lassa virus, endemic to West Africa, uses an unexpected two-step process to enter cells, research has shown. The results suggest that the mechanism by which Lassa virus causes infection is more complicated than previously known, and could lead to new approaches for preventing the disease.

A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.
For decades, scientists have believed that cellular divis... Read More
Material from deadly pathogens triggers alerts directly, and could speed detection. Early detection is key to slowing outbreaks of Ebola, such as the one currently spreading across west Africa that is estimated to have infected almost 1000 people, according to the latest World Health Organizatio...

David writes (re lice and iron):
All I remember that I know is that one time I let my cat endure a heavy flea infestation for an unconscionably long time. I redeemed myself, if at all, by the knowledge that I slept with her a lot, and so endured a share myself (b... Read More
The joys of anaerobic digestion
One U.K. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce. Yum.
A Sainsbury's store in Cannock in central England is getting access to anaerobic digesters. The store plans to use electricity solely from the dige... Read More
A former student dropped by my lab this morning, and brought me a gift: a knit bacteriophage! Many times, as educators, we hear what we haven't done well, or could do better. Sometimes, like today, we get a priceless "thank you" from a former student. Read More
This is the time of the year of increased physical activity when we pay special attention to certain parts of the body, including the armpit. As is usually the case, our microbiota is involved because the odor associated with sweating is produced by microbial activity. The main culprits are skin... Read More
Scientists in the United States and India have successfully modified the precursor to one of the drugs used to treat tuberculosis, an important first step toward new drugs that can transcend antibiotic resistance issues that experts consider a serious threat to global health.
The findings, re... Read More
A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
Hello TWiM team,
A few years back Rogan Brown moved from London to a remote region of France. “It was an overwhelming experience,” he says, “and as an artist I was looking for a way to come to terms with my new environment.” Landscape painting seemed too staid, so he started trying to recreate bits of the teemin...

Urea is a small molecule formed as proteins are broken down. It’s excreted in urine, but isn’t particularly toxic at low levels so it’s found in cells throughout the body. The molecular structure of urea is below, and as it contains nitrogen (N) several pathogens have adapted to use it as a nitr... Read More
