Ebola, a virus that causes deadly hemorrhagic fever in humans, has no known cure or vaccine. But a new study by University of Illinois at Chicago scientists has uncovered a family of small molecules which appear to bind to the virus's outer protein coat and may inhibit its entry into human cells...

Converting the code contained in genes to the proteins that make up a living organism is one of the most important and highly regulated tasks performed within a cell. A new tool from Howard Hughes Medical Institute (HHMI) scientists is offering researchers a new ability to freeze that process at... Read More
A new vaccine strategy using nanoparticles as carriers may be the key to developing a vaccine against norovirus, one of the most common causes of foodborne disease in the United States. Researchers from the Cincinnati Children's Hospital Medical Center report promising findings in the January 20... Read More
Thanks to the H1N1 flu virus, researchers may have found a key to developing a universal flu vaccine. According to a University of Chicago and Emory University study, people infected with H1N1 in 2009 developed antibodies to other flu strains. So, researchers believe that when given the correct ...

Australian scientists using new image and cell technologies have for the first time caught malaria parasites in the act of invading red blood cells. The researchers, from the Walter and Eliza Hall Institute in Melbourne, Australia, and the University of Technology, Sydney (UTS), achieved this lo... Read More
As it turns out, wearing the same pair of denim jeans nearly every day for 15 months isn't all that dirty after all.
Josh Le, 20, is a third-year University of Alberta student who, alongside professor Rachel McQueen, discovered the bacterial count of a 15-month worn and unwashed pair of jeans... Read More
Last week, as Haiti remembered the 230,000 people killed in the disaster, officials of international health agencies fine-tuned their recommendations for moving forwards with a large-scale cholera-vaccination programme. It is a controversial idea that, just months ago, with little vaccine availa... Read More
In anticipation of a May 2011vote in which the World Health Assembly (the decision-making body of the World Health Organization) will decide on whether to set a date for the destruction of America and Russia's stockpile of smallpox virus, the journal Nature argues that some of these collections...

In case anyone needs it, I have a copy of the classic 80's tome "The Winner's Book of Video Games" which provides several sure-fire Pac-Man patterns that ensure victory (+ maxi points) on each level. With any luck, those patterns SHOULD hold true at a paramecia level . . . Read More
For the first time, researchers have discovered that some slime molds can carry, seed, and harvest a crop of their bacterial diet, researchers from the University in Houston, Texas, report in this week's issue of Nature.
"While collecting D. discoideum fruiting bodies in the wild, Debra Brock... Read More
Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria.
Chemists at the Univ. of Illinois and collaborators in Taiwan studied a type of enzyme found in humans, plant... Read More
Over half a million babies are born preterm every year in the U.S. alone, leaving these children to bear significantly elevated risk of death, morbidity, and developmental problems. The way a fetus responds to inflammation in the uterus appear to contribute to the risk of preterm labor, but wha... Read More
After months of speculation about what will happen to the Gulf oil spill, it turns out Mother Nature has rolled up her sleeves and dispatched with a lot of the gas released along with it—in just four months.
Surprisingly, practically all of the methane that accompanied nearly five million bar... Read More
Transferring antibodies from the blood of recovering swine flu patients to those still suffering from the virus could provide a treatment of last resort.
Ideally, those most at risk of flu should be vaccinated, and in mild cases antivirals like Tamiflu can be taken after infection to treat th... Read More
Since this article was first posted on 6 January, Brian Deer has stuck the knife in one last time in the third and final of his investigatory papers. Today he channels his criticism at the role The Lancet and the medical community played in what he claims was an apparent cover-up of the flaws in... Read More
While Florida farmers have lost much of their crop to cold weather for the second year in a row, they say a fast-spreading, incurable bacteria presents a greater threat to their trees and the citrus industry.
Citrus greening has destroyed groves in the U.S., Brazil, Asia and Africa. Detected ... Read More

Is bacterial DNA contamination in your whole genome amplification kit a problem? For microbiologists it sure is. WGA is a technique where the complete genomic content of a sample is amplified non-specifically and at a single temperature (isothermically). The presence of any contaminating DNA in ... Read More
