Close up view of the edges of an unknown bacteria swabbed form the bottom of a shoe, possible Bacillus, on TSA exhibiting spreading and rhizoid growth. The pigment is opaque white-beige with a mucoid surface towards the center of the colony and a matte surface towards the edges. Note: transmit... Read More
Researchers who have fought for years to get full data on Roche's flu medicine Tamiflu said on Thursday that governments who stockpile it are wasting billions of dollars on a drug whose effectiveness is in doubt.
In a review of trial data on Tamiflu, and on GlaxoSmithKline's flu drug Relenza,... Read More
Pick an archaeon, any archaeon, and you will find it has a story to tell. Not all archaea are exotic but plenty of them are. These stalwarts live in environments we humans call extreme, where they carry out what to us seem extreme types of metabolic conversions. Most have come rather late into o... Read More
The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... 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

Uzbek microbiologist Dilfuza Egamberdieva hopes to apply her new agricultural technique soon in Uzbekistan to boost the yield of economically important crops such as wheat, cotton, tomato and cucumber. She presented her work at this year's TWAS General Meeting.
Egamberdieva, group leader at t... Read More
Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nan... Read More
Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.
Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More
As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... Read More
An international research group led by Arizona State University professor Qiang "Shawn" Chen has developed a new generation of potentially safer and more cost-effective therapeutics against West Nile virus, and other pathogens. The therapeutics, known as monoclonal antibodies (MAbs) and their de... Read More
Desperate for breast milk, some new mothers who can't nurse their babies are turning to online sources, typically strangers with ample supplies. But a new study finds that human milk bought and sold on the Internet may be contaminated — and dangerous.
Nearly 75 percent of breast milk bought t... Read More
A new probiotic for pigs could mean less manure to manage, according to U.S. Department of Agriculture (USDA) studies. Agricultural Research Service (ARS) scientists conducted the first published investigation of the use of bacteria as a probiotic to increase fiber fermentation rates and reduce ... Read More
Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More
Microbial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen’s evolutionary trajectory. Toxicity, the ability to destroy host cell membranes, and adhesion, the ability to adhere to human tissues, are the major virulence factors of many bacterial pathogens... Read More
I haven't read it (yet) but heard Daniel Keyes' 1960 short story/1966 novel is a sci-fi masterpiece.
And it's the first place my mind went upon reading about this fascinating breakthrough by researchers at Yale. Read More
It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.
The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More
The humble baker's yeast has been enlisted to serve the needs of humanity, responsible for beer, wine and bread, among other staples. A domesticated servant for at least millennia, the microscopic fungus has now had one of its chromosomes swapped out by a host of undergraduate students in favor ... Read More
Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More
