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
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
EURAC and University of Vienna discover an opportunistic pathogen in an Iceman tissue biopsy
Ötzi’s human genome was decoded from a hip bone sample taken from the 5,300 year old mummy. However the tiny sample weighing no more than 0.1 g provides so much more information. A team of scientist... 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
The symbiosis between some plant species and nitrogen-fixing nodule bacteria is one of the most relevant cooperative relationships in the world. It shapes our global vegetation and, not least, the global nitrogen and carbon cycle. The foundations for this process were probably laid in just one e... Read More
Those of us who write about infectious diseases faced a conundrum last week, when the news broke that 60-year-old vials containing viable smallpox virus had been found on the National Institutes of Health campus. A responsible reporter always wants to talk to the experts in any subject. But when... 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
We may think of ourselves as just human, but we’re really a mass of microorganisms housed in a human shell. Every person alive is host to about 100 trillion bacterial cells. They outnumber human cells 10 to one and account for 99.9 percent of the unique genes in the body.
Katrina Ray, a senio... Read More

Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More
Like ecosystems the world over, the human microbiome is losing its diversity, to the potential detriment of the health of those it inhabits.
Dr. Martin J. Blaser, a specialist in infectious diseases at the New York University School of Medicine and the director of the Human Microbiome Program... Read More
Concrete is the most widely used building material in the world, with untold amounts being produced yearly. It has always been regarded as a strong, solid, impenetrable, almost indestructible material yet it can make cracks that are vulnerable to penetration by water. As the result, structures ...

Health workers have called the Ebola outbreak in West Africa unprecedented, overwhelming and even out of control.
With 844 cases so far, it's the largest and deadliest outbreak since the virus was discovered in 1976. And it doesn't show signs of slowing down. On Tuesday, the World Health Orga... Read More
Researchers from the University of Southern California and the Oak Crest Institute of Science have discovered the link between antibiotics and bacterial biofilm formation leading to chronic lung, sinus and ear infections. The study results, published in the current issue of PLOS ONE, illustrate ... Read More
Many studies have shown that more severe illness and even death are likely to result if you develop a secondary respiratory infection after developing influenza. Now, however, a team of researchers based at The Wistar Institute has determined that if you reverse the order of infection, the bacte... Read More
After much rejoicing at the news last month that LEGO would mass-produce a set of female scientist minifigures, the company has released a prototype of the final set to its original designer, Ellen Kooijman (a.k.a. Alatariel Elensar), who recently posted images of the box and individual parts on... Read More
Disappointed federal officials today announced that the “Mississippi baby,” thought to have been cured of HIV with an aggressive treatment regimen, now has detectable levels of virus. The sad news, upsetting for the family of the 46-month-old girl, also dashed the hopes of clinicians who believe... Read More
MIT study finds ocean bacteria follow predictable patterns of daily activity.
We are all creatures of habit, and a new MIT study finds ocean bacteria are no exception.
In a paper published this week in Science, researchers from MIT and elsewhere report that microbes in the open ocean follo... Read More
