Eat candy and fight tooth decay. What a sweet concept, right?
Well, microbiologists in Berlin are trying to make that dream a reality.
They've created a sugarless mint that's aimed at washing out cavity-causing bacteria from your mouth. And the candy works in a curious way: It's spiked wit... Read More
By tracking the previously unknown movements of a set of specialized cells, Whitehead Institute scientists are shedding new light on how the immune system mounts a successful defense against hostile, ever-changing invaders.
Central to the immune response is the activity inside structures know... Read More
For the millions of people suffering from the intensely red, horribly itchy skin condition known as eczema, the only thing more maddening than their disease is the lack of understanding of what causes it, or makes it flare up from time to time.
In a paper published online in Nature, the team ... Read More
A new imaging technique for studying the structure of a childhood disease, respiratory syncytial virus (RSV), could provide scientists with the information they need to develop new antiviral drugs and perhaps even a vaccine to prevent severe infections.
By the time they’re two years old, most... Read More
Normally we shudder when we think of bacteria, but a new study reveals that some of these microorganisms may be able to help us lose weight.
The study, published in the March 27 issue of Science Translational Medicine, showed that bacteria in the guts of mice changed after they had gastric by... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Two subtypes of human papillomavirus (HPV) prevented by vaccines are half as likely to be found in African-American women as in white women with precancerous cervical lesions, according to researchers at Duke Medicine.
The findings, presented on Oct. 28, 2013, at the 12th annual International... Read More
If we could somehow rewind the history of life to the dawn of the animal kingdom, it would be unlikely that we humans would ever evolve, the evolutionary biologist Stephen Jay Gould argued. The history of life was shaped by too many flukes and contingencies to repeat its course.
Scientists ca... Read More
The vast majority of researchers in the science field are honest and conscientious. But that's not the case for all of them, and a federal agency that tracks misconduct and cheating in the field is seeing increases.

The University of Liverpool is to decipher the genomes of the UK’s main bacterial cause of food poisoning which results in over 21,000 hospital admissions and 100 deaths each year. Using the latest whole genome sequencing technologies available at the University’s Centre for Genomic Research, sc... Read More
Hello Team TWiM,
I’ve followed with interest your coverage of Michael’s research into use of copper to fight hospital infection. Of all the interesting papers covered in 2013, I think the one most actionable is episode 55, The Copper Room. His res... Read More
Dungeons & Dragons co-creator Gary Gygax touched the lives of the people who loved his games. So when the legendary Dungeon Master died in March 2008, players around the world showed their thanks with heartfelt tributes –including naming a species of bacteria after him.
Arthronema gygaxiana i... Read More
History has repeatedly shown that contagion makes an easy bedfellow with human conflict.
Take the poliovirus outbreak in Syria - and Israel and Egypt too - caused by related strains that can be traced back to Pakistan.
War and insurgency provide the ideal conditions for bacteria and viruse... Read More
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon. Researchers at the University of Massachusetts, Amherst report their findings at the 113th General Meeting of the A... Read More
Scientists have a promising new approach to combating deadly human viruses thanks to an educated hunch by University of California, Riverside microbiology professor Shou-Wei Ding, and his 20 years of research on plants, fruit flies, nematodes and mice to show the truth in his theory.

The Caribbean Sea is battling an epidemic — a nasty plague that spreads and kills quickly. Unlike the historical Black Plague, which killed millions of people in the Middle Ages, this so-called white plague is devastating populations of marine corals.
Scientists long believed the scourge, whi... Read More
The poster child for basic research might well be a one-celled green algae found in ordinary lakes and ponds. Amazingly, this unassuming creature—called Chlamydomonas—is helping scientists solve one of the most complex and important mysteries of science: How billions of neurons in the brain inte... Read More
Membrane proteins are the “gatekeepers” that allow information and molecules to pass into and out of a cell. Until recently, the microscopic study of these complex proteins has been restricted due to limitations of “force microscopes” that are available to researchers and the one-dimensional res...

HPV self-testing is as effective as tests done by doctors, according to a Lund University study. Simple HPV home tests could therefore complement existing screening programmes, and identify more women at risk for cervical cancer.
Sweden has a system of regular gynaecological smear tests, whic... Read More
The benefits and risks of "gain-of-function" research into highly pathogenic microbes with pandemic potential must be evaluated, scientists say. A group of over 50 researchers has called on the European Commission to hold a scientific briefing on research that involves engineering microbes to m... Read More
