Chemists at Bar-Ilan University in Israel say they have developed and successfully tested "killer paper" coated with silver nanoparticles--each roughly 1/50,000 the width of a human hair--that can fight bacteria such as E. coli and S. aureus.
Described in the American Chemical Society journal... Read More

Scientists at The Scripps Research Institute have found that a known enzyme in cells protects against measles virus, likely by altering the virus's genetic material, RNA. Cells lacking the enzyme become highly vulnerable to the virus's destructive effects. The enzyme also protects against severa... Read More
Chris Upton, a contributor to the virology toolbox, has raised an important point about multiplicity of infection:
Perhaps this is a place to bring up particle to pfu ratio? The above is great for when talking about phage, for example, when the ratio approaches 1. But with something like poli... Read More
Do video games change behavior? This question may be the subject of debate for years, but researchers have now shown the answer to be yes—for microorganism behavior, at least.
A research group led by Stanford bioengineering professor Ingmar Riedel-Kruse has developed several real video games,... Read More
Haloarcula marismortui, a micro-organism that lives in the salty waters of the Dead Sea, is the proud owner of a unique metabolic pathway. So far it is only the third pathway of its kind uncovered in organisms that use oxygen, seemingly cobbled together using genes stolen from bacteria.
When ... Read More
An RNA molecule engineered to attack HIV in two different ways is showing positive results, according to a study in Science Translational Medicine. The researchers say that the molecule, which both curbs viral replication inside infected cells and neutralizes free-floating virus, could help pati... Read More

George Clooney is battling the potentially fatal tropical disease malaria, it was revealed last night.
The 49-year-old star contracted the illness in Sudan, north-east Africa, which he has visited twice in the past three months. He was last there just a week ago.
He was there in December ... Read More
Transmission of prion brain diseases such as bovine spongiform enecephalopathy (BSE) – also known as mad cow disease – and human variant Creutzfeldt-Jakob disease (vCJD) is generally attributed to the consumption of the brain or organ meat of infected animals but new research demonstrates lambs ...

Another 142 deaths have been recorded in the UK in the past week from people with flu, bringing the total death toll since October to 254.
However, the Health Protection Agency (HPA) said the majority of these new deaths did not occur in the past seven days, but were the result of delays in r... Read More

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
