The Extra Pounds You Can't Afford to Lose: An Interview With Microbiologist Margaret McFall-Ngai

Recent revelations about our microscopic partners and tenants are numerically startling, if not downright existential. Try these for starters: Most of the cells within your body are not human cells, and you are literally teeming with pounds of busy microbes, working to earn their keep while you ... Read More

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

MicroRNAs and Retroviral Integrity

Jamie Henzy, a postdoctoral researcher at Boston College, has authored a post on Small Things Considered that explores the shady world of the deltaretrovirus genus.

"Among retroviruses, the deltaretrovirus genus is something of a shady bunch, its members lurking in the shadows, causing troubl... Read More

The Rise of Genomic Superspreaders

One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More

Worm kills insects by vomiting Hulk-like bacteria

Insects have been around for almost 400 million years. That’s plenty of time for evolution to fashion countless horrific deaths for them. Case in point: some insects die because a little worm vomits glowing bacteria inside their bodies.

The worm is Heterorhabditis bacteriophora, a microscopic... Read More

TWiV 190 Letters

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

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

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

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...

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 toward... 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...

HPV Vaccine Reduces Infection, Even in Unvaccinated: Evidence of 'Herd' Protection

The HPV vaccine not only has resulted in a decrease in human papillomavirus infection in immunized teens but also in teens who were not immunized.

The study is believed to be the first to show a substantial decrease in HPV infection in a community setting as well as herd protection -- a decre... Read More

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

100 trillion good bacteria call human body home

In the search for new life, scientists have studied the depths of the ocean and the lips of steaming volcanoes. They've looked on Mars and the moons of Jupiter, and even planets beyond this solar system.

Dr. David Relman went searching inside his own mouth. On a routine dental visit in 1998, ... Read More

Bacterial Vaginosis Is Associated with Higher Risk of Female-to-Male Transmission of HIV

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

The new research assessed the association between bacterial... 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

New approach of resistant tuberculosis

Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics ar... Read More
