Killer Silk: Making Silk Fibers That Kill Anthrax and Other Microbes in Minutes

A simple, inexpensive dip-and-dry treatment can convert ordinary silk into a fabric that kills disease-causing bacteria -- even the armor-coated spores of microbes like anthrax -- in minutes, scientists are reporting in the journal ACS Applied Materials & Interfaces. They describe a range of pot... Read More

Battling superbugs

Two new technologies could enable novel strategies for combating drug-resistant bacteria.

In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect... Read More

Amphibian communities collapse in wake of viral outbreak

Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six... Read More

MERS virus detected in air samples from Saudi camel barn

Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.

MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More

Deadly Bacteria Lurk in Deepwater Horizon Tar Balls

Nearly two years after the Deepwater Horizon disaster gushed millions of barrels of oil into the Gulf of Mexico, tar balls from the spill still turn up on Alabama's shores after storms. Now, one researcher is recommending that people steer clear of these tar balls after studies find them chock-f... Read More

Shigella Steals Host Nutrients... Economically

Intracellular pathogens face many daunting problems, among them how to obtain enough energy and nutrients for active growth while, preferably, keeping the host cell alive for as long as possible. This issue is especially acute for pathogens that grow at a fast rate and reach large numbers. When ... Read More

On the trail of the truffle flavour

German an French Scientists found out: Soil bacteria contribute to the taste and smell of white truffles.

Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of tru... Read More

Tick protein does the trick to fight infection

A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.

Scientists discovered that IAFGP, an antifreeze protein in ticks that kicks in during winter, also fights infection. Synthesizing such a protein ma... Read More

Major step forward in understanding of viruses as scientists unlock exact structure of Hep A virus

Scientists have announced that for the first time, they have determined the precise atomic structure of the Hepatitis A virus. In an unprecedented step forward, a team of scientists from Beijing and Oxford have been able to map the exact construction of Hepatitis A, down to the individual atoms.... Read More

Imaging electric charge propagating along microbial nanowires

Physicists report that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive human-mad...

Hospitals 'need friendly bacteria'

Lessons learned from Florence Nightingale could prevent the spread of harmful bugs by allowing "friendly" bacteria into hospitals, an expert has claimed.
Sterile conditions in wards and operating theatres may be doing more harm than good by wiping out organisms that keep dangerous microbes at b... Read More

Two More Questions about CRISPRs

Over the past eight years, step-by-step, researchers have established a basic understanding of the CRISPR defenses against foreign DNA so widely used by both bacteria and archaea. We related the early story on STC in 2008 and commented on six additional questions in 2011. Still, questions remain... Read More

How Did Nigeria Quash Its Ebola Outbreak So Quickly?

On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More

Dear water-based life forms:


It is 24 degrees in Overland Park, Kansas and I am looking at a slide labeled "Giardia lamblia", part of a museum exhibit on water and human (over) use of water.


I see a greenish lump. I don't kno... Read More
