Health officials are watching in horror as bacteria become resistant to powerful carbapenem antibiotics — one of the last drugs on the shelf.
As a rule, high-ranking public-health officials try to avoid apocalyptic descriptors. So it was worrying to hear Thomas Frieden and Sally Davies warn o... Read More
What happens when you use tiny electromagnetic coils to shift the position of light-scattering bacteria? In the hands of a couple of science-minded artists, you get an intriguing "Living Mirror."
I have a new favorite artist: bacteria. Imprinted onto cell phones, it can look like flowers, or ... 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
Excerpt from Science Now "Gut Microbes Can Split a Species"; see link above to read the Science article
Here's how to create a new species. Put animals—say finches—from the same species on separate islands and let them do their thing for many, many generations. Over time, each group will ada... Read More
Professor Yasien Sayed, research leader of the HIV Proteins Research Thrust, Protein Structure-Function Research Unit in the School of Molecular and Cell Biology, has led his group to international acclaim by solving the three-dimensional X-ray crystal structure of the South African HIV-1 subtyp...

The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More
The current hot spell of weather has seen increased activities by flies whether in the kitchen or across picnic food and barbecues.
It may make grim reading but every fly leaves a calling card in the form of bacterial deposits.
These deposits come not only from their legs, but also from th... Read More
What makes a harmless virus turn lethal? For the deadliest infectious disease in cats, Cornell scientists now know.
After gathering the world’s largest sample collection for feline infectious peritonitis (FIP), they uncovered the holy grail of a 30-year quest for the mutation that turns it fa... Read More
Health officials say they still don't understand how a lesser-known bird flu virus was able to kill two men and seriously sicken a woman in China, but that it's unlikely that it can spread easily among humans.
Two men in Shanghai became the first known human fatalities from the H7N9 bird flu ... Read More
Whether a man, a mouse or a microbe, stress is bad for you. Experiments in bacteria by molecular biologists in Peter Chien’s lab at the University of Massachusetts Amherst, with others at MIT, have uncovered the mechanism that translates stress, such as exposure to extreme temperature, into bloc...

Mathematicians have found that by varying the timing of treatments, doctors may be able to increase the odds that a disease outbreak will die off suddenly.
Herding cats is a cakewalk compared with getting people to take flu vaccine shots in the last weeks of summer—work, school, limited pharm... Read More
Viruses are obligate intracellular parasites: they must enter a cell to reproduce. To gain access to the cell interior, a virus must first bind to one or more specific receptor molecules on the cell surface. Cell receptors for viruses do not exist only to serve viruses: they also have cellular f... Read More
UC Davis scientists have uncovered a potential drug target for the development of an effective therapy against the debilitating, chronic form of the bacterial disease brucellosis, which primarily afflicts people in Mediterranean and Middle Eastern countries.
Brucellosis, which affects about 5... Read More
Finding that part of the story of Louis Pasteur's rabies vaccine is false, Héloïse Dufour and Sean Carroll explore how science fables are born, spread and die.
John Snow's ending of London's 1854 cholera outbreak, Joseph Lister's development of antiseptic surgery, Alexander Fleming's inventio... Read More
Famed astronomer and writer Carl Sagan said in his book Cosmos: “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” And so are microbes, we must add. To understand the s... Read More
Vampire bat venom could hold the key to new treatments for stroke and high blood pressure.
An international team of scientists led by UQ's Associate Professor Bryan Fry from the School of Biological Sciences has discovered that vampire bat venom contains molecules capable of evading the vict... 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
Testing every person in India’s billion-plus population every five years for HIV would not only be cost-effective but also could save millions of lives for decades to come, a new study suggests.
In India most people who are HIV positive don’t know it—even though testing and treatment are rela... Read More
Doses of a human gut microbe helped to reverse behavioural problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on pre... Read More
With increasing attention toward generating cost-effective biochemical conversion methods for producing biofuels, it helps to follow the leaders who have perfected the process. The mere Reticulitermes flavipes, or eastern subterranean termite, a famous feaster of lignocellulosic plant materials ... Read More
