Dear Twim Docs,
I just finished listening to the latest episode it Twim on the microbiote's effects on obesity. There was discussion about the use of donor feces in the treatment of human disease. I thought this might be of interest.<... Read More
MIT researchers find a way to boost lithium-air battery performance, with the help of modified viruses.
Lithium-air batteries have become a hot research area in recent years: They hold the promise of drastically increasing power per battery weight, which could lead, for example, to electric c... Read More

Molecular biologists at the University of Wyoming have found a molecular mechanism that allows myxobacteria to recognize related strains that lead to the transient fusion of their outer membranes to exchange lipids and proteins.
Results of the study, led by Associate Professor Daniel Wall in ... Read More

Middle East Respiratory Syndrome (MERS) is viral respiratory illness first reported in Saudi Arabia in 2012. It is caused by a coronavirus called MERS-CoV. Most people w... Read More
Several African nations could strike a major blow against malaria by sacrificing the efficacy of some older drugs. Can they make it work?
It is September in southeastern Mali, and Louka Coulibaly is standing in the shade of a squat, concrete building, giving instructions to a dozen men and wo... Read More
A group of Israeli researchers has succeeded in isolating a protein that kills bacteria, in what is a first step toward developing a substitute for antibiotics. The substance isolated by a Tel Aviv University team prevents bacteria from dividing, thus destroying them and combatting infections. “... Read More
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...

Pregnant women may transmit the damaging effects of stress to their unborn child by way of the bacteria in their vagina and through the placenta, suggest new findings from two animal studies presented by researchers at the University of Pennsylvania at Neuroscience 2013, the annual meeting of th...

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.
In the current issue of the Proceedings of the National Academy of Sciences, a Michigan St... Read More
