Built-in dengue virus killer found in humans

Scientists may have hit gold in their fight against dengue. They have located a human antibody that can neutralise and kill its virus within two hours.

Significantly, they have also identified a way to reproduce this antibody in large quantities, potentially opening the door to a cure for den... Read More

How medicine created a bacteria problem

On a warm afternoon in summer we were sitting in the lecture theatre, learning about germs. A microbiologist was showing us slides of enormously magnified bacteria (“God, this is like bug Imax!” said the girl behind me). The lecturer had a cold; he was coughing dramatically. After a prolonged bo... Read More

In First, Software Emulates Lifespan of Entire Organism

Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.

The scientists and other experts said the work was a giant step towar... Read More

Bacteria outbreak in Northern Europe due to ocean warming, study says

Manmade climate change is the main driver behind the unexpected emergence of a group of bacteria in northern Europe which can cause gastroenteritis, new research by a group of international experts shows.

The paper, published in the journal Nature Climate Change on Sunday, provided some of th... Read More

Meningitis Vaccine Being Developed From Common Cold Virus

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Princeton University researchers develop tooth attachment that detects bacteria

It may not be the latest style in bovine bling, but researchers at Princeton University say a golden tattoo attached to a cow’s tooth could one day tell you something about your health.

The remote sensing device has the ability to detect a single bacterium, and to demonstrate, scientists at P... Read More

Microbiologist Uses Viruses to Fight Bacteria

After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... Read More

Rapamycin, Easter Island Drug, Shows Promise In Boosting Aging Brain, Mice Study Shows

Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?

The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... Read More

Cat Litter Parasite Tied to Suicide Risk in New Moms

Mothers with IgG antibodies to Toxoplasma gondii at delivery are at risk for later self-harm or suicide, particularly if they have higher titers against the parasite, a Danish study found.

The risk of self-directed violent behavior was increased 1.53-fold (95% CI 1.27 to 1.85, Psk rose to 1.9... Read More

Hello Vincent and Team TWIV,


I love Virology, and it is with much chagrin that I admit I have only recently started listening to TWIV. However I have tried to mend the error of my ways by: 1) proselytizing the benefits (keeping up-to-date with and... Read More

How hosts recognize bacteria

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

Scientists Discover New Trigger for Immense North Atlantic Plankton Bloom

Across the horizon and miles out to sea toward the north, the Atlantic Ocean's own spring and summer ritual is unfolding: the blooming of countless microscopic plant plankton, or phytoplankton.

In what's known as the North Atlantic Bloom, an immense number of phytoplankton burst into color, f... Read More

Selection-driven Gene Loss in Bacteria

Bacterial genomes differ dramatically in size: from 140Kb to 13Mb (those numbers might be off now...please let me know if something has broken the record. Yes, I know the lower estimate can change based on semantics, but there are a bunch in that range). Although we have some clues as to how sel... Read More

How Bacteria Sense Salt Stress

Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More

Bird Flu Research That Stoked Fears Is Published

The more controversial of two papers describing how the lethal H5N1 bird flu could be made easier to spread was published on Thursday, six months after a scientific advisory board suggested that the papers’ most potentially dangerous data be censored.

The paper’s publication, in the journal S... Read More

Scientists reveal how natural systems limit the spread of "cheating" bacteria

In the first field study of its kind researchers at Royal Holloway, University of London and the University of Oxford have investigated the competitive dynamics of pathogenic and non-pathogenic strains of bacteria.

Bacteria are increasingly seen as living and interacting in groups and sharing... Read More
