Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
It is well known that aquatic birds are a major reservoir of influenza A viruses, and that pandemic human influenza virus strains of the past century derive viral genes from this pool. The recent discovery of two new influenza A viruses in bats suggests that this species may constitute another r... Read More

When an E. coli cell divides, it must replicate its circular chromosome and pull the resulting circles apart to take up residence in two new cells. It sounds easy enough—like a magician's trick with rings—but actually involves a complicated process of unknotting and unlinking of tangled DNA.

A dedicated website for sharing biology papers before peer review leaves journals divided.
What are biologists so afraid of? Physicists, mathematicians and social scientists routinely post their research to preprint servers such as arXiv.org before publication, yet few life scientists follow ... Read More
Purdue University researchers successfully eliminated the native infection preferences of a Sindbis virus engineered to target and kill cancer cells, a milestone in the manipulation of this promising viral vector.
"This virus had been known to be a good vector for delivering therapeutic cargo... Read More
Medical investigators for the first time have confirmed the MERS coronavirus in a camel, one belonging to a Saudi man also ill with the new virus, providing a critical clue into the virus's animal hosts and transmission, a top Saudi health official and an international disease expert said on Mon...

Bacterial proteins could alter precipitation patterns and climate-change models.
Proteins can help grow teeth and bones in the body, crops in the ground, and even ice in the atmosphere. Some proteins have an uncanny knack for kick starting ice formation at unusual temperatures, and they have ... Read More
On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming if... Read More
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.

Since its appearance in the U.S. seven years ago, white-nose syndrome has decimated bat populations across eastern North America. Scientists say they've determined the culprit—a soil-dwelling fungus called Pseudogymnoascus destructans—and now they're investigating novel ways to stop it, includin... Read More
A Dixieland band player who didn’t clean his clarinet for 30 years is recovering from a year-long allergic reaction caused by fungus that grew inside the reed instrument, experts said.
The 68-year-old unidentified Atlanta man came down with an intractable case of “saxophone lung,” an actual c... Read More
A Dutch bio-engineer says his lab-produced fungus could someday be used to save the lives of hungry people in the developing world.
But first, it might need some extra Rooster Sauce to make it go down easier.
"It has a very strong taste, a bitter aftertaste," says Hans van Leeuwen, a profe... Read More
Oman's first MERS coronavirus patient died in hospital on Sunday from lung failure, state news agency ONA said.
The Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which can cause coughing, fever and pneumonia, emerged in Saudi Arabia last year and has been reported in Qatar, France,... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More
