Ancient Viruses Gain New Functions in the Brain

If thinking about the billions of bacteria taking up residence in and on your body gives you the willies, you probably won’t find it comforting that humans are also full of viruses. These maligned microbes are actually intertwined in the very fibers of our being—about 8 percent of our genetic ma... Read More

Seeking single cells’ secrets

The National Institutes of Health has awarded grants totaling $7.9 million in 2014 to 25 research teams who are unraveling the workings of single cells, as part of an effort to spur development of personalized treatments that target disease at the cellular level. The grants are supported by the ... Read More

"Extreme measures" needed to see Ebola shot development through

Developing and bringing to market effective Ebola vaccines requires extreme measures and unprecedented international cooperation, global health experts said on Monday.

In an interim report on a roadmap for vaccines against the current and any future outbreaks of the deadly virus, infectious d... Read More

Obama to seek more funds for antibiotic-resistant bacteria fight

President Barack Obama will request a doubling of funds for fighting and preventing antibiotic-resistant bacteria in his 2016 budget, the White House said Tuesday.

The goal is to expand US investment in developing of antibacterial and new rapid diagnostics and launch a major effort to charact... Read More

Viroids, infectious agents that encode no proteins

Genomes of non-defective viruses range in size from 2,400,000 bp of dsDNA (Pandoravirus salinus) to 1,759 bp of ssDNA (porcine circovirus). Are even smaller viral genomes possible? The subviral agents called viroids provide an answer to this question.

Viroids, the smallest known pathogens, ar... Read More

Deadly bacteria on medical scopes trigger infections

The deadly pattern of illnesses began to emerge in 2012 at hospitals in Seattle, Pittsburgh, Chicago. In each case, the culprit was a bacteria known as CRE, perhaps the most feared of superbugs, because it resists even "last defense" antibiotics — and kills up to 40% of the people it infects.

Trust your gut: E. coli may hold one of the keys to treating Parkinson's

E. coli usually brings to mind food poisoning and beach closures, but researchers recently discovered a protein in E. coli that inhibits the accumulation of potentially toxic amyloids—a hallmark of diseases such as Parkinson's.

Amyloids are formed by proteins that misfold and group together, ... Read More

Cold Plasma Treatment May Reduce Risk of Norovirus Transmission

Treating surfaces with cold atmospheric pressure plasma (CAPP) may reduce the risk of transmitting norovirus, a contagious virus leading to stomach pain, nausea and diarrhea, according to a new study.

The Real Contagion of Anti-Vaccine Idiocy

Quinn Cummings is a writer of three books, Notes From the Underwire, The Year of Learning Dangerously and Pet Sounds.

When a 'personal choice' becomes a health crisis

I glanced at my phone and frowned — why on earth was my daughter’s pediatrician calling me at seven at night?

TWiV 321: aTRIP and a pause

Paul Duprex joins the TWiV team to discuss the current moratorium on viral research to alter transmission, range and resistance, infectivity and immunity, and pathogenesis.


Hosts: Vincent Racaniel... Read More

Satellites - the viral kind

Satellites are subviral agents that differ from viroids because they depend on the presence of a helper virus for their propagation. Satellite viruses are particles that contain nucleic acid genomes encoding a structural protein that encapsidates the satellite genome. Satellite RNAs do not encod... Read More

Mapping for Ebola: A Collaborative Effort

One of the difficulties faced by teams responding to the current Ebola outbreak in West Africa is identifying individuals and communities residing in remote areas. Existing maps of these regions either do not exist or are inadequate or outdated. This means that basic data like location of houses... Read More

Compound keeps virus sealed in its "pocket"

A new class of compounds may be an effective way to fight a virus that leaves children with serious respiratory infections and might be associated with polio-like symptoms.

Researchers used a technique called X-ray crystallography to learn the precise structure of the original strain of enter... Read More

Test developed by UAB scientists could help fight deadly infection

Researchers from UAB have developed a tool for diagnosing bacterial meningitis that uses the same technology as a home pregnancy test.

The test measures the level of certain proteins that are present in the spinal fluid of patients with bacterial meningitis. If the level is high, the test wil... Read More

Diabetes in rats treated with engineered probiotic

Imagine a pill that helps people control diabetes with the body’s own insulin.

Cornell researchers have achieved this feat in rats by engineering human lactobacilli, a common gut bacteria, to secrete a protein called Glucagen-like peptide 1 (GLP-1).

A 2003 study led by Atsushi Suzuki of th... Read More

What Are the Consequences of Antibiotic Overuse?

The development and widespread adoption of so-called “antibiotics”—drugs that kill bacteria and thereby reduce infection—has helped billions of people live longer, healthier lives. But all this tinkering with nature hasn’t come without a cost. The more we rely on antibiotics, the more bacteria d... Read More

Predicting superbugs' countermoves to new drugs

With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades -- such as pneumonia or urinary tract infections -- are proving trickier to treat with standard antibiotics.

New drugs are desperately needed, but so are ways to maximize the effective lif... Read More

Genetic changes in Ebola virus in West African outbreak could hinder potential treatments

WASHINGTON, DC--January 20, 2015--Researchers have tracked the genetic mutations that have occurred in the Ebola virus during the last four decades. Their findings, published in mBio®, the online open-access journal of the American Society for Microbiology, identified changes in the current West... Read More

Harnessing bacteria to move microscopic gears and ratchets

Previous research has already demonstrated that substantial quantities of self-motile or active agents such as bacteria in a fluid environment can be harnessed to do mechanical work like moving microscopic gears and ratchets. Bacteria as well as algae can also be used to transport or displace ma... Read More
