U.S. flu activity low, but Los Angeles confirms a women died

U.S. influenza activity remains low, but Los Angeles County confirmed its first death -- a woman with an underlying medical condition, an official says.

Dr. Jonathan E. Fielding, director of public health and health officer, says the woman resided in the San Fernando Valley and the particular... Read More

Equine gut bacteria probed in pilot study

The gut bacteria in horses are being researched at the University of Pennsylvania, in a series of projects that scientists hope will ultimately benefit animal and human health.

Researchers at the university’s School of Veterinary Medicine are leading five pilot projects as part of the wider i... Read More

Bacteria work together to create energy from sunlight

Bacteria, with their ability to grow, develop and sustain themselves in a variety of conditions, could be the miniature powerhouses that could drive us to a clean energy future.

Researchers at Arizona State University’s Biodesign Institute are studying certain bacteria’s ability to produce el... Read More

Scientists Re-Code Genome of E. Coli Bacterium

Scientists from Harvard and Yale came together to achieve what was once thought impossible: to fundamentally transform the identity and properties of an organism by re-coding its genome.

According to the study published this month in the journal Science, the scientists successfully developed ... Read More

Study: Panda immune system more resilient than previously understood

New research shows giant pandas have a stronger immune system than previously known, because the panda immune system develops different antigens depending on where it lives.

This genetic diversity is a natural defense against extinction, because it means a single pathogen cannot wipe out the ... Read More

Flu virus wipes out first wave of immune response

The immune system has the capacity to "remember" particular viruses and store those details in B memory cells that reside in the lungs to help ward off future infections. But a new study shows the flu virus takes advantage of this and uses the way the memory cells store its details to recognize ... Read More

It’s in the Genes

Scouring the genomes and body-wide microbial communities of 93 people, researchers have discovered a link between the composition of the microbiome and genetic variation in innate immunity, phagocyte function, and other immune pathways. The research was presented by University of Minnesota popul... Read More

Profile: Dr. Michael Noble: a microbiologist with a passion for patient safety in lab testing

Forty million lab tests are done in B.C. annually. Each and every one is an opportunity for human error leading to patient harm.

In a bid to avert errors in collection, handling and analysis, a small team at the University of B.C. manufactures simulated specimens to send to labs across Canada... Read More

Making Hydrogen Cheaply by Imitating Bacteria? Unique Chemistry in Hydrogen Catalysts Revealed

Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them.

How bacteria with a sweet tooth may keep us healthy

Some gut bacterial strains are specifically adapted to use sugars in our gut lining to aid colonisation, potentially giving them a major influence over our gut health.

We live in a symbiotic relationship with trillions of bacteria in our gut. They help us digest food, prime our immune system ... Read More

Japan tests in Chile bacteria-based method to revive depleted copper mines

A Japanese government-backed firm has begun testing a new technology to extract copper by using sulphuric acid mixed with multiple species of bacteria at a mine in Northern Chile.

Japan Oil, Gas and Metals National Corp., known as JOGMEC, will conduct a two-year large-scale experiment to exam... Read More

Dangerous Fungus Makes A Surprise Appearance In Montana

What life-threatening illness can you get from repotting plants, attending a rodeo or going spelunking? If you didn't guess histoplasmosis, you're not alone.

This week's Morbidity and Mortality Weekly Report, chronicle of all things infectious, reports on the surprising appearance of histopla... Read More

Cold virus 'treats prostate cancer' for Birmingham patient (video)

A patient in Birmingham has undergone landmark gene therapy to treat prostate cancer.

The treatment, developed by doctors at University Hospital in Birmingham over the past 15 years, uses a virus modified from the common cold to deliver a powerful chemotherapy drug which at the same time stim... Read More

Your Ethnicity Determines the Species of Bacteria that Live in Your Mouth

In recent years, scientists have found out all sorts of remarkable things about a group of creatures that are entirely invisible to the naked eye: the trillions of bacteria that colonize every surface of our bodies.

These organisms—collectively known as the microbiome—deeply affect our health... Read More

Cantilever sensory array: The Rosetta Stone for antibiotic resistance? (press release)

On October 25, JoVE, the Journal of Visualized Experiments will publish a novel technique to confront the problem of antibiotic resistance. According to Dr. Joseph Ndieyira, one of the developers involved in the technique, "The use of this technology will allow scientists to understand how antib... Read More

Fungus that causes white-nose syndrome in bats proves hardy survivor

After taking an in-depth look at the basic biology of a fungus that is decimating bat colonies as it spreads across the U.S., researchers report that they can find little that might stop the organism from spreading further and persisting indefinitely in bat caves.

Their report appears in the ... Read More

Recalling the Good in the Good Old Days

In its early days, ca. 1945-1965, molecular biology was a particularly collegial undertaking, characterized by free sharing of research data and a relative lack of egotistical behavior. The reason for this marvel may well have been that there was so much to discover—so many low hanging fruits—th... Read More

Devastating frog fungus triggers suicide by immune cells

A deadly fungus spreading like wildfire through amphibian populations causes immune cells to commit suicide, a new study finds. The chytrid fungus Batrachochytrium dendrobatidis kills frogs and other amphibians by infecting the skin, interfering with fluid and electrolyte levels, and ultimately ... Read More

90 percent of workers come to work when sick

(MoneyWatch) Do you go to work when you know you are contagious? Chances are, the answer to that is yes, according to a new study by Staples, which finds that 90 percent of American workers go to work when they are knowingly contagious. This is up from 80 percent who said they came to work while... Read More

Bacteria-sniffing wand could help prevent foodborne illnesses

One in six Americans (or 48 million people) get foodborne illnesses every year. Better detection can lower that number dramatically. Bacteria detection sniffers have been studied for several years now. They are based on a wireless acoustic wave sensor platform, which is a fancy way of saying tha... Read More
