Pediatrician Jennifer Halverson will never forget her 36th birthday.
The St. Paul native was volunteering at a maternity clinic in Port-au-Prince, Haiti. She felt great — she went to her job that day and then out to dinner with friends.
But when she got home and went to sleep that night in... 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 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
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 microbial ecosystem in the human gut can switch from one stable state into another, without staying for a long time in between. Key groups of bacteria tend to be either nearly absent, or relatively abundant in any given individual. This discovery highlights fundamental organizing principles ... Read More
Hi, I am doing a research in Cryptosporidium parvum and Cyclospora cayetanensis infection among School children of kathmandu at Public health research laboratory, the Institute of Medicne, kathmandu.
This is a Modified ZN stained image of Cyclospora cayetanensis isolated form a 5 year School... Read More
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
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
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...

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
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
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
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More
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
A new combination drug therapy cures chronic hepatitis C in most patients also infected with HIV—and without the side effects of current treatments.
The advance is important, researchers say, because about a third of HIV patients in the United States also have hepatitis C. There are an estima... Read More
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...

Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a s... Read More
One of the Wellcome Trust’s areas of focus for research funding is combatting infectious disease. We have recently agreed a strategic award of over £7.5 million to continue development of an effective and sustainable approach to reducing the transmission of dengue fever. The research is an inte... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More
