Single-celled archaea are invisible to the naked eye, and even when using a microscope, great care must be taken to observe them. An international team of researchers led by the Center for Geomicrobiology, Aarhus University, Denmark, has nevertheless succeeded in retrieving four archaeal cells f... Read More
The latter half of the 19th century was a critical period in the development of Western, or what is now complimentarily called modern, medicine. The famed chemist Louis Pasteur and the physician Robert Koch established on a firm intellectual foundation the notion that the cause of infectious dis... Read More
Scientists at the University of Texas and the University of Iowa have created a synthetic bacteria that grows thanks to one of humankind's favorite stimulants — caffeine. According to a report from Quartz, this bacteria can be added to any caffeinated beverage and it'll grow according to the lev... Read More
Adorning your living room mantel with a petri dish full of germs normally wouldn’t sound appealing. But once you take a look at Zachary Copfer’s unique creations, you might be intrigued — if you’re not already running to the bathroom to wash your hands.
Copfer is a Cincinnati-based microbiolo... Read More
A nasty fungal infection that can spread to the lungs or brain and cause lifetime symptoms is on the rise in the Southwestern U.S., federal health officials reported on Thursday. Cases of Valley Fever, known medically as coccidioidomycosis, have increased nearly 10-fold between 1998 and 2011, th... Read More
Plant waste has long been seen as a possible source of sustainable biofuels, and new research out of Rice University could unlock some of the energy that scientists say lies waiting in organic material.
According to materials provided by Rice, bioengineer Ka-Yiu San and his lab have developed... Read More
Producing vaccines against viral threats is a potentially hazardous business and that's why manufacturers have to operate strict controls to ensure that no pathogens escape.
British scientists have developed a new method to create an entirely synthetic vaccine which doesn't rely on using live... Read More
BBC medical correspondent Fergus Walsh explains how British scientists have used a new technique to develop a synthetic virus which heralds a major development in vaccines.

The mysterious SARS-like virus that appears to be originating in the Middle East has claimed two more victims after people died from the infection in Germany and in Britain.
Their deaths brings to 11 the number of fatalities attributed to the virus, and six others have been determined to have... Read More
Northwestern Medicine scientists have identified a component of the herpesvirus that "hijacks" machinery inside human cells, allowing the virus to rapidly and successfully invade the nervous system upon initial exposure.
Led by Gregory Smith, associate professor in immunology and microbiology... Read More
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
