Drug resistant bacteria are, justifiably, a serious cause for concern. Most of the attention has focused on mutations or genes that confer resistance to our current repertoire of antibiotics. But bacteria have a second way to avoid being offed by our drugs: a tiny fraction of many bacterial spec... Read More

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
Scientists have identified a potential way to improve future flu vaccines after discovering that seasonal flu typically escapes immunity from vaccines with as little as a single amino acid substitution. Additionally, they found these single amino acid changes occur at only seven places on its su... Read More
The deadliest known outbreak of a measles-like virus in bottlenose dolphins has killed a record number of the animals along the US Atlantic coast since July, officials said Friday.

Methanotrophs (bacteria that use methane for their carbon and energy) secrete siderophore-like compounds that are usually used to chelate copper and make it more bioavailable, but ... Read More
Johns Hopkins researchers report that the deletion of any single gene in yeast cells puts pressure on the organism’s genome to compensate, leading to a mutation in another gene. Their discovery, which is likely applicable to human genetics because of the way DNA is conserved across species, coul... Read More

Dr. John Spencer is a mycobacteriologist studying leprosy at Colorado State University. He has collaborators in the northern state of Para, Brazil, who visit schoolchildren in about 10 different cities in the Amazon region and elsewhere to diagnose and treat kids and family members who have t...

For most people, a fungal infection like athlete's foot means a simple trip to the drugstore and a reminder to bring shower shoes to the gym. But in very rare cases, fungal infections can spread below the skin's surface and onto the lymph nodes, bones, digestive tract or even the brain. Research... Read More
Slowly over the past year, a novel respiratory virus has claimed victims in the Middle East, primarily in Saudi Arabia. It comes from a species known as coronavirus, which, through an electronic microscope, looks like a spiky blob. The virus has been named Middle East respiratory syndrome, or ME... Read More
Ancient viruses from Neanderthals have been found in modern human DNA by researchers at Oxford University and Plymouth University.
The researchers compared genetic data from fossils of Neanderthals and another group of ancient human ancestors called Denisovans to data from modern-day cancer p... Read More
Do you eat bread? Or drink beer? If so you've probably consumed yeast products from the National Collection of Yeast Cultures.
Yeasts are one of the earliest, if not the earliest, biological tools used by people. Brewers' yeast, Saccharomyces cerivisae, features widely in products we consume... Read More
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...

Did you see this paper in PLoS Computational Biology? It's mind-blowing. U. Maryland researchers found evidence for Acinetobacter and Pseudomonas nucleic acid integrated into human chromosomes and mitochondria, po... Read More
A woman who tested positive for hepatitis C after potentially coming into contact with a hospital worker who had the virus is worried she infected her family.
Angela Richards, from Caerphilly, has been told the virus is no longer present and it could not be confirmed whether she had been infe... Read More
Braunschweig have now discovered what makes a specific strain of Yersinia pseudotuberculosis—one of the main instigators for these infections–so dangerous: the bacteria produce a molecule called CNFy that facilitates the infection process for them. It changes the host cells in a manner that enab... Read More
By unleashing a genetically modified virus onto microscopic electrode wires, researchers from MIT have shown that the performance of lithium-air batteries can be significantly improved -- a remarkable breakthrough that could revolutionize the way our electric devices are powered.
Indeed, lith... Read More
