Ebola: a new pandemic? (video)

Ebola is transmitted from person to person through direct contact with the body or with body fluids of an infected person. Ebola virus is NOT a respiratory virus and is NOT transmitted through the air. It is not a gastrointestinal virus either, so it is NOT generally transmitted via water or foo... Read More

CDC Announces Active Post-Arrival Monitoring for Travelers from Impacted Countries

The Centers for Disease Control and Prevention (CDC) announced that public health authorities will begin active post-arrival monitoring of travelers whose travel originates in Liberia, Sierra Leone, or Guinea. These travelers are now arriving to the United States at one of five airports where e... Read More

Bacteria are more promiscuous than expected, since plasmids invade unexpectedly diverse fraction of soil bacteria

Conjugal plasmids provide microbes with full complements of new genes. Conjugal plasmid transfer is deemed responsible for the rapid spread of antibiotic resistance among microbes. While broad host range plasmids are known to confer transfer abilities to diverse hosts in pure culture, the extent... Read More

A recent study of biofilm formation in an archaeon revealed a fascinating form of social motility

A study of biofilm formation in the model haloarchaeal species Haloferax volcanii has led to the observation of a fascinating example of coordinated social motility (and of cellular differentiation and gene transfer). Haloferax volcanii was first isolated from Dead Sea sediment in 1975, but was ... Read More

Middle-Aged Adults Were More Susceptible to the Flu Last Year because of a New Viral Mutation

A team of scientists, led by researchers at The Wistar Institute, has identified a possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season. The findings, published in the Proceedings of the National Academy of Sci... Read More

Shaking up cell biology: Researchers focus in on decades-old mitochondrial mystery

Elvis did it, Michael Jackson did it, and so do the mitochondria in our cells. They shake. While Elvis and Michael shook for decades before loud and appreciative audiences, mitochondrial oscillations have quietly bewildered scientists for more than 40 years.

Now, a team of scientists at Natio... Read More

Antibiotics may help Salmonella spread in infected animals, scientists learn

Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.

When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More

Dear Colleague Letter on the Ebola Virus

Dear Colleague,

In light of the recent emergence of the lethal Ebola virus in the US, the National Science Foundation (NSF) is accepting proposals to conduct non-medical, non-clinical care research that can be used immediately to better understand how to model and understand the spread of Ebo... 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...

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

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

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
