Adding a related virus can boost vaccines

The results of a clinical trial suggest it is possible to modify the body’s response to an infection with a related virus.

The researchers report in Nature Microbiology that antibodies, under specific conditions, can intensify infection with a virus related to the causal organism. This phenom... Read More

Researchers discover rare flu-thwarting mutation

A rare and improbable mutation in a protein encoded by an influenza virus renders the virus defenseless against the body's immune system. This University of Rochester Medical Center discovery could provide a new strategy for live influenza vaccines in the future.

A new approach to the live fl... Read More

Viruses found to attack ocean archaea far more extensively than thought

A team of researchers with members from Italy, Australia, the U.S. and Japan has found that viruses are the main culprit in killing archaea in the deep sea. In their paper published in the journal Science Advances, the researchers describe the techniques they used to study archaea in soil sample... Read More

These are the foods you should eat if you want less smelly farts

Eating slow-release carbs and cutting down on protein may prevent rotten-egg farts according to a study of the gases emitted by human faeces samples.

Farts are mostly composed of odourless gases. There is oxygen and nitrogen from swallowed air, while hydrogen, methane and carbon dioxide are p... Read More

Endangered frog recovers thanks to resistance to deadly fungus

For decades a deadly fungus has been slaughtering amphibians around the world, driving many to the brink of extinction or even beyond.

But now one frog’s recovery shows that, with a little luck and habitat preservation, some amphibians may be able to evolve resistance to the fungus.

In lab... Read More

Bacteria can make underground nuclear waste repositories safer

Naturally occurring bacteria could consume pent-up hydrogen gas in nuclear waste repositories to prevent radioactive leaks, say researchers at EPFL.

Scientists may have found an unexpected ally in the long-term disposal of nuclear waste: bacteria. In a recent study, a research team led by EPF... Read More

How the Zika Virus Could Make Its Way to North America

Laboratory tests show that a cold-tolerant mosquito known as Culex quinquefasciatus can be infected with Zika virus in the laboratory. If confirmed in the field, it would be a troubling development, suggesting the virus would be more difficult to control, and might be able to spread far north of... Read More

Professor, graduate student unravel mystery of bacteria's antibiotic resistance

A popular antibiotic called rifampicin, used to treat tuberculosis, leprosy, and Legionnaire’s disease, is becoming less effective as the bacteria that cause the diseases develop more resistance.

One of the mechanisms leading to rifampicin’s resistance is the action of the enzyme Rifampicin m... Read More

Global warming collapses symbiotic gut bacteria, killing host insects

A new study shows that when heat-susceptible bacteria living symbiotically in the guts of insects are exposed to increased temperatures, both the bacteria and the insect are negatively impacted and can die. The study, reported online this week in the journal mBio®, illustrates another way globa... Read More

Global Warming Damages Symbiotic Organisms

Ten years ago, Takema Fukatsu, PhD, prime senior researcher and leader, National Institute of Advanced Industrial Science and Technology (AIST) in Japan, was invited to Kyoto University as a symposium speaker of a meeting organized by Kenji Fujisaki, PhD, a researcher in the University's Graduat...

New, carbon-nanotube tool for ultra-sensitive virus detection and identification

A new tool that uses a forest-like array of vertically-aligned carbon nanotubes that can be finely tuned to selectively trap viruses by their size can increase the detection threshold for viruses and speed the process of identifying newly-emerging viruses.

"Early detection is important becau... Read More

Scientists Identify Potential Antivirals Against Chikungunya

Chikungunya virus has caused two recent massive outbreaks sickening millions of people. Now a team of researchers has shown that several existing compounds have potent activity against the critical CHIKV protease enzyme. The research is published October 10 in Antimicrobial Agents and Chemothera... Read More

TWiV 410: Hurricane Zika

Sharon and Scott join the TWiV team to talk about their work on dengue antibody-dependent enhancement of Zika virus infection, and identifying the virus in mosquitoes from Miami.

Hosts: Vince... Read More

S. mutants mutation increases fluoride resistance

Microbes are excellent at adapting to stressful situations, which is part of the reason antibiotic resistance is a problem today. Constant exposure to antimicrobials such as triclosan have selected for resistant strains, rendering the compound ineffective. This is why the FDA recently banned t... Read More

Antimicrobial resistance gene found in marine pathogen

A team of Chinese investigators has discovered a gene for resistance to β-lactamase antibiotics, in the pathogenic marine bacterium, Vibrio parahaemolyticus. The β-lactamase gene, blaVEB-2, has never before been found in V. parahaemolyticus, and in fact, has been found almost exclusively in non-... Read More

World's first dengue fever vaccine launched in the Philippines

Dengue fever infects 390 million people each year, and kills as many as 25,000, according to the World Health Organization.

The disease could soon see these numbers decline as the Philippines start administering the world's first dengue vaccine to high-risk children.

The historic drug took... Read More

TWiV 409: A Nef is enough

Jeremy joins the TWiVeroids to tell the amazing story of how the function of the HIV-1 protein called Nef was discovered and found to promote infection by excluding the host protein SERINC from virus particles.

Hosts:  Read More

Complete Genome Sequence of Zika Virus Isolated from Semen

A team of researchers from the United Kingdom has obtained the first complete genome sequence of Zika virus that was isolated from a semen sample. The research is published this week in Genome Announcements, a journal of the American Society for Microbiology.

The motivation for this investiga... Read More

Grand Challenge: Mapping the Human Immune System

A team of scientists has created a genetic map of all possible receptors the human immune system might generate—also known as the immunome.

The project involved a mind-boggling data set.

“If we were on a treasure hunt, where the cure to many illnesses is the buried treasure, then we’ve jus... Read More

Zika likely to spread in Asia Pacific: WHO

The Zika virus is set to spread through Asia, the World Health Organization warned Monday, with hundreds of cases reported in Singapore and two Thai babies diagnosed with Zika-linked microcephaly.

The mosquito-borne virus has been detected in 70 countries worldwide including at least 19 count... Read More
