In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neu...

Until relatively recently, the fungus Malassezia was thought to have one favorite home: us. As the dominant fungus on human skin and sometimes-cause of dandruff, the yeast Malassezia was thought to live a simple if sometimes irritating domestic existence humbly mooching off the oils we exude.

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

In this post, I meet up with six of my former undergraduate students at the General Meeting of the American Society of Microbiology in Boston last May. We had a great dinner where we could catch up on challenges and cheer each other on. I am very proud of the great students in this post, who a... Read More
Natural selection favours those with a greater capacity to generate genetic variation.
Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidl... Read More
A glass of orange juice in the morning is something many of us take for granted. But that might soon change thanks to a citrus disease affecting every major orange-growing region in the world.
The world's orange crop is being threatened by "citrus greening," a bacterial infection carried by a... Read More
A study led by St. Jude Children’s Research Hospital scientists found the avian influenza A H3N8 virus that killed harbor seals along the New England coast can spread through respiratory droplets and poses a threat to humans. The research appears in the current issue of the scientific journal Na... Read More
Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.
That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.
Evolution is so important for biology, medicine and a genera... Read More
New research published in the online journal PLoS Outbreaks predicts new Ebola cases could reach 6,800 in West Africa by the end of the month if new control measures are not enacted.
Arizona State University and Harvard University researchers also discovered through modelling analysis that th... Read More
Scientists have long believed that microorganisms that produce methane swim toward the hydrogen gas they need to stay alive, but it has been too hard to prove in the lab.
Montana State University researchers have now overcome those challenges, allowing them to verify it for the first time, sa... Read More

Researchers working in the UK and The Gambia, have developed a new approach to the diagnosis of tuberculosis (TB) that relies on direct sequencing of DNA extracted from sputum (a technique called metagenomics) to detect and characterize the bacteria that cause TB without the need for time-consum...

Twitter clips human thoughts to a mere 140 characters. Animals’ scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them.
In the current issue of the Proceedings of the National Academy of Sciences, a Michigan St... Read More
Two months after safety breaches at federal labs first set off a public furor, top health officials are auditioning new checks on worker safety including specialized time-lapse cameras and digital worksheets to track crucial steps such as bacterium inactivation. The goal: to prevent future debac... Read More
In May 1984, readers of an article by Schwartz and Cantor in the prestigious journal Cell were to stumble upon pictures of DNA agarose gels that were among the lousiest of such ever published after the method was introduced in the early 70s. Why did the editors of Cell risk their reputation? Or ... Read More
Multiple sclerosis (MS), a central nervous system disease that often leads to paralysis and vision problems, affects approximately 2.3 million people worldwide and has no cure. Though no one knows what triggers MS, researchers have long suspected that a combination of genetic and environmental f... Read More
Caribbean health experts warned last week that they “cannot stop” a rapidly spreading mosquito-borne virus that has infected thousands and is associated with six deaths in the region.
The alert came as the Dominican Republic’s health ministry became the 15th Caribbean nation to confirm cases ... Read More
Viruses are supposed to be small and simple—not even alive, just mobile genetic material after all. So what do we make of giant double-stranded DNA (dsDNA) viruses, one of which—the newly discovered Pandoravirus salinus—has an even larger genome than a hunky parasitic eukaryote called Encephalit...

As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More
