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...

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

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

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

'Breath test' shows promise for diagnosing fungal pneumonia

Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... Read More

Airborne Environmental Isolate/Fungal view 1

An unknown airborne environmental isolate on Bile Esculin Agar (BEA) exhibiting a single circular colony. White hyphal growth with no spore formation. Clear to brownish exudate can be seen throughout the colony. This sample grew at refrigerated temperatures for several months. The agar surroun... 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

Lessons from the ‘Spanish Flu,’ Nearly 100 Years Later

Just in time for flu season, a new Michigan State University study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases.

Siddharth Chandra, director of MSU’s Asian Studies Center and professor in MSU’s James Madison Colle... Read More

Could Reston virus be a vaccine for Ebola virus?

I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not... 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

Ebola: a new pandemic?

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

Viral-research moratorium called too broad

Us government ban on research into enhanced pathogens also affects flu surveillance and vaccine work.

US researchers are worried that a temporary government ban on 'gain-of-function' experiments that boost the infectious properties of dangerous viruses may also cover less-extreme forms of the... Read More

During the last few years, Cyanine5 flurophore (analog of Cy5) has become an incredibly popular label of amino-groups in peptides, proteins, and oligonucleotides. Fluorophore emission has maximum in red region, where many CCD detecto... Read More

Fecal Transplanters Fish Out Key Ingredient

These days, antibiotics are no silver bullet. In fact, if you get them in the hospital, you may end up with an additional infection. Like the bug Clostridium difficile, or C. diff — which infects more than 300,000 Americans a year and kills some 14,000. C. diff flourishes in the post-antibiotic,... Read More
