Good microbiologists question assumptions. How about the assumption that semesters are the best calendars for learning? What would happen if rather than taking four courses concurrently during a semester, students instead took those four courses successively, one at a time? This describes the Co... Read More

Using stripped-down versions of living cells, researchers have confirmed which proteins allow certain bacteria to breathe iron and other metals when oxygen isn't available. Shewanella oneidensis (pictured) is often found in oxygenated environments but can also thrive without the gas if it must,... Read More

Fresh fruit and vegetables carry an abundance of bacteria on their surfaces, not all of which cause disease. In the first study to assess the variety of these non-pathogenic bacteria, scientists report that these surface bacteria vary depending on the type of produce and cultivation practices.

Bacteria that live in the gut change after gastric-bypass surgery, and may aid in weight loss, according to a Harvard University study.

Researchers gave mice the stomach-shrinking surgery and monitored changes in the gut’s bacterial inhabitants, according to a study in the journal Science Tra... Read More

Here is a short post about life in academia (with some rules) and some "rules" I have developed in teaching undergraduate students about Life in the Lab! Read More

The first evidence of cases of the Schmallenberg virus (SBV) among livestock bred and raised in Scotland has been confirmed.

Eight cows on the Barony Campus of Scotland's Rural College in Dumfries and Galloway have tested positive for SBV antibodies.

It indicates exposure to the virus at s... Read More

From the shiny, strong nacre that gives abalone shells an unbreakable, opaline sheen, to the goopy mix of proteins fired by a velvet worm that solidify and trap prey upon impact, nature is packed with inspiration for scientists designing new materials.

Waterproof adhesives and self-cleaning s... Read More

Governments, funders and regulatory authorities must urgently address the risks posed by gain-of-function research, says Simon Wain-Hobson. Barely two months after a small group of influenza virologists lifted a moratorium on work to make the H5N1 avian flu virus as transmissible between humans... Read More

Earlier this month the European Molecular Biology Laboratory (EMBL) published the DNA sequence of the genome of HeLa cells, the cell line that is widely used for research in virology, cell biology, and many other areas. This cell line was produced from a tumor taken from Henrietta Lacks in 1951.... Read More

A Kansas State University-led team is researching ways to stop the spread of norovirus, a contagious stomach illness that infects one in 15 Americans each year, according to the Centers for Disease Control and Prevention.

Kyeong-Ok Chang, associate professor of diagnostic medicine and pathobi... Read More

How much a person eats may be only one of many factors that determines weight gain. A recent Cedars-Sinai study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity.

The study, published online T... Read More

Older adults who harbor certain infections, such as the herpes cold sore virus, may have poorer thinking and memory abilities than their peers, a new study suggests.

Researchers found that of more than 1,600 older adults, those with signs of chronic infection with herpes simplex and certain o... Read More

Bacteria could soon be acting as microscopic "bio-batteries" thanks to a joint UK-US research effort.

The team of scientists has laid bare the power-generating mechanism used by well-known marine bacteria.

Before now it was not clear whether the bacteria directly conducted an electrical ch... Read More

The Galveston National Laboratory lost one of five vials containing a deadly Venezuelan virus, according to the University of Texas Medical Branch, which owns the $174 million facility designed with the strictest security measures to hold the deadliest viruses in the country.

Like Ebola, the ... Read More

Certain Streptococci increase their production of toxic shock syndrome toxin 1, sometimes to potentially dangerous levels, when aerobic bacteria are present in the vagina. But scientists from the University of Western Ontario have discovered certain strains of lactobacillus bacteria are capable ... Read More

A prototype medical dressing that 'lights up' when dangerous bacteria are present has been developed at the University of Bath. The invention means that life-threatening infections in child burn victims could in future be detected with nothing more than a UV light.

The dressing contains nanoc... Read More

David Bhella, Ph.D., MRC Centre for Virus Research, accepts the Peter Wildy Prize for Microbiology Education, awarded annually by the Society for General Microbiology for an outstanding contribution to microbiology education. Read More

Observing microbes in nature is a challenge. Compared to what goes on in the lab, there is not much one can do with them out there. So, instead of bringing the bacteria to the lab, why not bring the lab to the bacteria? Imagine being able to capture the expression of genes of a community of micr... Read More

Researchers have used whole genome sequencing to reveal if drug-resistant bacteria are transmitted from animals to humans in two disease outbreaks that occurred on different farms in Denmark. The results, which are published today in EMBO Molecular Medicine, confirm animal-to-human transmission ... Read More
