Pathogen Protection And Virulence: Dark Side Of Fungal Membrane Protein Revealed

Researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and Montana State University have discovered a fungal protein that plays a key role in causing disease in plants and animals and which also shields the pathogen from oxidative stress.

The researchers have found that t... Read More

How bacteria can spontaneously adapt to environmental changes

An international team of scientists has for the first time observed an evolutionary strategy called 'bet hedging' under laboratory conditions. The term bet hedging describes the way in which organisms ensure the survival of their species in rapidly changing environments by generating offspring s... Read More

Zinc inhibits rhinovirus replication - profvrr does an experiment

I was given a package of zinc lozenges when I contracted a cold a few weeks ago. That got me interested in the effect of zinc on rhinovirus replication. As a consequence I began a series of experiments to understand the mechanism of inhibition of viral replication by this metal. It's unusual tha... Read More

10 Ways Companies Are Cashing In On Swine Flu

The Business Insider outlines 10 ways companies, legitimate and not-so-legitimate, are cashing in on H1N1.

"As we head into flu season, the hysteria is ramping up all over again, and what that really means is profit! From body suits, to vaccines, emergency food packs, and underground bunkers.... Read More

Mutant Bacteria Are Likely to Threaten Future Space Travelers

When humans eventually travel to Mars and beyond, they'll have plenty to worry about along with the discomforts of eating freeze-dried food and drinking their own urine. A new report says they will probably be really sick, to boot -- from flare-ups of E. coli, chicken pox or staph infections.

New gene therapy halts 2 boys' rare brain disease

French scientists mixed gene therapy and bone marrow transplants in two boys to seemingly halt a brain disease that can kill by adolescence. The surprise ingredient: They disabled the HIV virus so it couldn't cause AIDS, and then used it to carry in the healthy new gene.

The experiment marks ... Read More

After Setbacks, Small Successes for Gene Therapy

Not long ago, gene therapy seemed troubled by insurmountable difficulties. After decades of hype and dashed hopes, many who once embraced the idea of correcting genetic disorders by giving people new genes all but gave up the idea

But scientists say gene therapy may be on the edge of a resurg... Read More

Frigid Antarctica Loaded with Viruses

Antarctica's icy lakes are home to a surprisingly diverse community of viruses, including some that were previously unidentified.

At first glance, Antarctica's freshwater lakes don't seem very hospitable to life. They remain frozen for a good nine months out of the year, and they contain very... Read More

Podcasts as Tools in Introductory Environmental Studies

A recent paper in the Journal of Microbiology and Biology Education by Christine Vatovec and Teri Balser examines the effectiveness of using podcasts as an educational tool.

Out of 209 survey respondents, the authors found:

"The majority of students reported enjoying using the podcasts in... Read More

Map Of Human Bacterial Diversity Shows Wide Interpersonal Differences

A University of Colorado at Boulder team has developed the first atlas of bacterial diversity across the human body, charting wide variations in microbe populations that live in different regions of the human body and which aid us in physiological functions that contribute to our health.

Bacterial antibiotic resistance genes discovered

Antibacterial soap, hand sanitizer and antibiotics are all substances that we use in an attempt to kill bacteria that might make us sick.Whether we are concerned about getting strep throat, bacterial meningitis or something else, these prevention methods can offer protection.

How Bacteria Get Past Our Defenses

Mucus is more than gross--it's a critical barrier against disease, trapping many of the germs that want to invade your body. A wet mesh of proteins, antiseptic enzymes and salts, mucus is what keeps all but a few microbes from wreaking havoc on many of our most exposed tissues.

Helicobacter p... Read More

Survey of Academic Life Scientists Suggests 10-Year Drop in Industry Funding

Direct industry funding for academic life science research appears to have decreased in the last decade, according to the results of a 2007 survey published this week.

The survey also found that academic life scientists with industry support withheld data or delayed publication due to commerc... Read More

Plants and Bacteria 'Talk' to Thwart Disease

In plant and animal innate immunity, like many of the dances of life, it takes two to tango. A receptor molecule in the plant pairs up with a specific molecule on the invading bacteria and, presto, the immune system swings into action to defend against the invasion of the disease-causing microbe...

Human microbes are picky about neighbourhoods on body

Your body is home to 10 times as many microbes as its own cells. But they can be quite picky about where they will settle – and what other bacteria they'll share fences with.

That's the conclusion of the most comprehensive map ever of the microbial communities flourishing in the human body.
