Small Comfort: Nanomedicine Able to Penetrate Bodily Defenses

Researchers use stealthy nanoscale particles to infiltrate vaginal mucus and keep herpes at bay in mice.

Tears and a runny nose can be unpleasant on a windy day, but these mucosal secretions play a vital role in protecting the body from viruses and other malicious microbes. Unfortunately, muc... Read More

Air pollution and tuberculosis may be connected

In a new study, scientists have determined a possible link between exposure to a common component of urban air pollution and a change in the function of important immune cells that protect against the bacteria that cause tuberculosis.

In their finding, a team of researchers, led by Dr. Steph... Read More

Ultra high-res images with no-lens microscope

A new electron microscope that works without a lens may create the highest resolution images ever seen.

Transmission electron microscopy (TEM), which looks through an object to see atomic features within it, has been constrained for over 70 years by the relatively poor lenses that are used to... Read More

The Microbial Academy of Sciences: What Bacteria Can Discover That We Can’t

Other than basic stuff like the Earth rotating around the sun and E=MC2, how much do you know about the universe? Most people would say: not very much. But if you’re a theoretical physicist, you probably know quite a bit more--but still not that much; most of the mysteries of the universe still ... Read More

A mad cow in America

A dairy cow in California is the fourth known American case of mad cow disease, which is caused by prions, infectious agents composed only of protein (the story hit the press the day after my lecture on this type of illness). Unlike viruses, prions have no nucleic acid and no protective coat. Bu... Read More

Computer-Designed Proteins Programmed to Disarm Variety of Flu Viruses

Computer-designed proteins are under construction to fight the flu. Researchers are demonstrating that proteins found in nature, but that do not normally bind the flu, can be engineered to act as broad-spectrum antiviral agents against a variety of flu virus strains, including H1N1 pandemic infl...

Intestinal artillery launches anti-bacterial attack

The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.

The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

Fungus behind America's bat die-off traced back to Europe

The mysterious deaths of millions of bats in the United States and Canada over the past several years were caused by a fungus that hitchhiked from Europe, scientists reported Monday.

Experts had suspected that an invasive species was to blame for the die-off from "white nose syndrome." Now th... Read More

The Extra Pounds You Can't Afford to Lose: An Interview With Microbiologist Margaret McFall-Ngai

Recent revelations about our microscopic partners and tenants are numerically startling, if not downright existential. Try these for starters: Most of the cells within your body are not human cells, and you are literally teeming with pounds of busy microbes, working to earn their keep while you ... Read More

Meningitis Vaccine Being Developed From Common Cold Virus

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Some Like It Very Hot

Russian scientists have now poured 60 tonnes of freon and kerosene down the four-kilometre bore hole that plunges through the ice above Lake Vostok in Antarctica. This will stop the hole freezing up during the long Antarctic winter. When summer comes, the Russian team will return to drill the la... Read More

Schmallenberg virus: What, where, how?

As Schmallenberg virus is confirmed on 74 farms in the UK, our environment correspondent Richard Black looks at what the virus is, what it does and how it can be tackled.

What is Schmallenberg virus?
Schmallenberg virus is a disease of farm animals that was first seen last year in northern E... Read More

How medicine created a bacteria problem

On a warm afternoon in summer we were sitting in the lecture theatre, learning about germs. A microbiologist was showing us slides of enormously magnified bacteria (“God, this is like bug Imax!” said the girl behind me). The lecturer had a cold; he was coughing dramatically. After a prolonged bo... Read More

Built-in dengue virus killer found in humans

Scientists may have hit gold in their fight against dengue. They have located a human antibody that can neutralise and kill its virus within two hours.

Significantly, they have also identified a way to reproduce this antibody in large quantities, potentially opening the door to a cure for den... Read More

Aaron J. Shatkin, 77

Aaron J. Shatkin was well known for his work on reoviruses beginning in the 1960s in his laboratory at the Roche Institute of Molecular Biology in Nutley, NJ and then at Rutgers University. He was among the first to appreciate that virus particles contained many different enzymes, such as RNA po... Read More

Microbiologist Uses Viruses to Fight Bacteria

After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... Read More

Slow-Motion Microbes Still Living off Dino-era "Lunch Box"

Buried under the seafloor for 86 million years, a bacterial community lives so slowly it's still surviving on a "lunch box" from dinosaur days, a new study says. (See marine-microbe pictures.)

It's been known since the 1990s that microbes can live trapped in ocean sediments for millions of ye... Read More

Kids Have Little Protection from New Flu Virus

Children younger than 10 likely will be the most susceptible if a variant of the influenza A (H3N2) virus -- dubbed A (H3N2)v -- develops the ability to transmit easily among humans, researchers found.

Since August 2011, there have been 12 cases of infection with the variant -- which contains... Read More

Rapamycin, Easter Island Drug, Shows Promise In Boosting Aging Brain, Mice Study Shows

Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?

The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... Read More
