Without swift influx of substantial aid, Ebola epidemic in Africa poised to explode

The Ebola virus disease epidemic already devastating swaths of West Africa will likely get far worse in the coming weeks and months unless international commitments are significantly and immediately increased, new research led by Yale researchers predicts.

The findings are published in the Oc... 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

Viral Infection Might Just Be a Phase...Transition

Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?

In two separate studies, Carnegie Mellon University biophysicist Alex Evilevitch has shown t... Read More

In Hopes Of Fixing Faulty Genes, One Scientist Starts With The Basics

Whether they admit it or not, many (if not most) scientists secretly hope to get a call in October informing them they've won a Nobel Prize.

But I've talked to a lot of Nobel laureates, and they are unanimous on one point: None of them pursued a research topic with the intention of winning th... Read More

The Epstein–Barr Virus Wears Chain Mail

The Epstein–Barr virus and its relatives in the herpesvirus family are known for their longevity. They persist in host tissues for years, causing diseases like mononucleosis, Kaposi's sarcoma and herpes, and are notoriously difficult to kill. University of California, Los Angeles, biophysicist Z... Read More

Study reveals how deadly MERS virus enters human cells

Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

Bioinspired coating for medical devices repels blood and bacteria

From joint replacements to cardiac implants and dialysis machines, medical devices enhance or save lives on a daily basis. However, any device implanted in the body or in contact with flowing blood faces two critical challenges that can threaten the life of the patient the device is meant to hel... Read More

Divide and Conquer: novel trick helps rare pathogen infect healthy people

New research into a rare pathogen has shown how a unique evolutionary trait allows it to infect even the healthiest of hosts through a smart solution to the body’s immune response against it.

Scientists at the University of Birmingham have explained how a particular strain of a fungus, Crypto... Read More

CDC Launches Ebola Response Team

In the two days since the second U.S. Ebola patient was diagnosed, the U.S. Centers for Disease Control and Prevention (CDC) has assembled a new team to battle the threat of Ebola. This team has no steady lineup, but it will be deployed anywhere in the country that sees a new case of Ebola, CDC ... 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

Chromosome Organization the Pseudomonas Way, Part 1

(Re-)Introducing the Pseudomonads. Despite the somewhat murky provenance of their name, pseudomonads are everything but "pseudo-" in terms of their metabolic versatility: they are bacterial omnivores, heterotrophs yet far from picky. Members of the family Pseudomonadaceae (Gammaproteobacteria) 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.

Mineralization of sand particles boosts microbial water filtration

Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Microbiology. These findings resoundingly refute, for the first time, the... Read More

Positive clinical results indicate vaccine candidate is highly efficacious against bacterial diarrhea

New results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate that a live attenuated enterotoxigenic Escherichia coli (ETEC) vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease. This repr... Read More
