Missing Nitrogen May Be Vanishing in the Tubes of Giant Bacteria

Off the coast of Mexico’s Baja Peninsula lies a dark, still, deep place. It is called the Soledad Basin, and in it lies a garden of bacteria so large you can see them with your own eyes.

A 250-m high ridge on the edge of the Soledad basin traps water inside. No strong currents disturb its dep... Read More

Human decomposition: study maps internal bacteria

We may not be so different from zombies when we die, after all. A new study analyzing bacterial communities involved in the decomposition of corpses illustrates how a cadaver becomes a living, thriving ecosystem for microorganisms.

The study, published recently in PLOS ONE, reveals that the t... Read More

New flu virus found in Peruvian bats

A brand new flu virus has been found in Peruvian bats, according to a new study from researchers at the Centers for Disease Control and Prevention.

Scientists 3-D Print Tiny Cages That Imprison Bacteria

Scientists at The University of Texas at Austin have figured out how to make structures – like houses or cages – that are small enough to corral bacterial cells. The enclosures can be built in any shape and are 3-D printed using a modified laser, the team reported Oct. 7 in Proceedings of the Na... Read More

Immune System May Affect Germs on Your Skin

Your immune system influences the types of microorganisms that live on your skin and affect your risk for disease, according to a new study. A person's skin contains millions of beneficial and potentially disease-causing microbes. Previous research has shown that these microbes influence the imm... Read More

Bacterial communities shift during human decomposition, Sam Houston U & Baylor researchers reveal

New research conducted by researchers at Sam Houston State University and Baylor College of Medicine revealed that bacterial communities around a corpse could change overtime as human decomposition progresses. The study has appeared on October 30th in the open-access journal PLOS ONE, titled “Th... Read More

Germ-hunting antibodies suppress HIV-like virus in monkeys; may hold key to new treatment

Doctors may one day be able to control a patient’s HIV infection in a new way: injecting swarms of germ-fighting antibodies, two new studies suggest. In monkeys, that strategy sharply reduced blood levels of a cousin of HIV. The results also gave tantalizing hints that someday the tactic might h... Read More

Are Farm Veterinarians Pushing Too Many Antibiotics?

In a barn outside Manhattan, Kan., researchers from Kansas State University are trying to solve the riddle of bovine respiratory disease. They're sticking plastic rods down the noses of six-month old calves, collecting samples of bacteria.

"This bacteria, Mannheimia haemolytica, lives in most... Read More

New Look at Old Test May Provide Earlier Detection of Meningitis

Researchers from the University of Missouri School of Medicine have found a more accurate method to screen for bacterial meningococcal infection in its early stages, when it's hardest to detect. According to the researchers, the method for diagnosis could save lives by getting patients treatment... Read More

Scientists raise alarm over today's measures against Legionellosis

According to the textbooks, both high doses of chlorine and hot water are lethal to legionella bacteria. But now Norwegian scientists are sounding the alarm that the bacteria can survive these treatments, by hiding in amoebae.

Legionella bacteria can cause deadly pneumonia via our shower wate... Read More

Biotransformation of Enniatins from Fusarium Fungi in a Food Safety Perspective

Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More
