For the first time, scientists report, they have found bacteria living in the cold and dark deep under the Antarctic ice, a discovery that might advance knowledge of how life could survive on other planets or moons and that offers the first glimpse of a vast ecosystem of microscopic life in unde...

A few days ago, the Food and Drug Administration released two important documents related to antibiotic use in livestock raising, and what the results of that antibiotic use are. I’d say that they released them quietly, except, when it comes to this issue, every release seems to be quiet, never ... Read More
Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all ... Read More

It is generally a mystery how new diseases arise and how the pathogens that cause them first enter countries. However, clues may come from examination of specimens from similar outbreaks. This approach has recently been taken by scientists at the University of Veterinary Medicine, Vienna to trac... Read More
Scientists have long puzzled over why "bad" bacteria such as E. coli can thrive in the guts of those with inflammatory bowel disease (IBD), causing serious diarrhea. Now UC Davis researchers have discovered the answer -- one that may be the first step toward finding new and better treatments for... Read More
What do microbes have to do with beer? Everything! Because the master ingredient in beer is yeast – a microbe – and every step in the brewing process helps the yeast do its job better. A new freely-available report; "FAQ: If the Yeast Ain’t Happy, Ain’t Nobody Happy: The Microbiology of Beer" ex... Read More
A pair of commentaries to appear in an upcoming issue of the journal Antimicrobial Agents and Chemotherapy highlight a debate within the public health community surrounding Centers for Disease Control and Prevention (CDC) recommendations for treatment of exposed individuals during last year’s fu...

The UK dog population is estimated to be around ten million, with dogs producing approximately 1,000 tonnes of excrement each day. New research has shown that dogs act as a major source of the parasite egg, Toxocara, which can potentially contaminate the public environment and infect humans.

Genes relocated from their correct position in the nucleus cause them to malfunction and this may lead to the heart, blood vessels and muscles breaking down. This new discovery by A*STAR scientists may be the key to finding new cures in the future.
Scientists from Singapore and Germany have i... Read More
One of the most critical biological advances in the past decade was the discovery that the introduction of four simple genetic factors can turn a fully mature adult cell back into an embryonic-like state, a process called reprogramming.

Penicillin-producing fungus, previously thought to be asexual, has a sexual side. The finding is the latest in a kind of sexual revolution in fungal genetics. By turning off the lights, setting up an oatmeal-based bed and slipping some extra vitamins into their food, researchers have persuaded t... Read More
The lethality of avian influenza H5N1 infections in humans has been a matter of extensive debate. The >50% case fatality rate established by WHO is high, but the lethality of the virus might be lower if there are many infections accompanied by mild or no disease. One way to answer this question ... Read More
The study suggests that the new whooping cough strain is resistant to Pertactin, a component of the acellular vaccines. This resistance may be why we are seeing increase in the number of people getting the disease.
Pertactin-Negative Variants of Bordetella pertussis in th... Read More
Scientists hope that one day in the distant future, miniature, medically-savvy computers will roam our bodies, detecting early-stage diseases and treating them on the spot by releasing a suitable drug, without any outside help. To make this vision a reality, computers must be sufficiently small ... Read More
An international collaboration of researchers from the U.S. Army Medical Research and Materiel Command (USAMRMC), Tunisia and France has demonstrated a high cure rate and remarkably few side effects in treating patients with cutaneous leishmaniasis (CL) with an investigational antibiotic cream. ...

There's nothing quite like the pastime of cloud watching. We can spend hours watching these ethereal formations pass by. We can find shapes in them, try to imagine where they came from -- and where they are going -- and whether or not they are going to open up and douse us with precipitation.

UT Southwestern Medical Center scientists have synthesized a peptide that shows potential for pharmaceutical development into agents for treating infections, neurodegenerative disorders, and cancer through an ability to induce a cell-recycling process called autophagy.
Autophagy is a fundamen... Read More
Epigenetic controls like histone modification and chromatin remodeling play important regulatory roles in all cellular processes requiring access to the genome. So when a herpes simplex virus or varicella-zoster virus infects a human cell, one of the first things it does is attack the cell’s epi... Read More
A team of scientists just won a battle in the war against antibiotic-resistant "superbugs" -- and only time will tell if their feat is akin to the bacterial "Battle of Gettysburg" that turns the tide toward victory.
They won this particular battle, or at least gained some critical intelligenc... Read More
