While natural selection is best known for weeding out the weak, it may also be partly responsible for the apparent rise of some disorders, such as autism, autoimmune diseases and reproductive cancers, according to researchers.
Since evolutionary factors play a role in disease, the two fields ... Read More
Scientists from University of Rochester Medical Centre have developed a gene therapy by bringing together herpes virus and a molecule, which will help fight diseases of the brain and nervous system.
With the new technique, they dramatically increased the size of the "genetic payload" they can... Read More
Sanofi-Aventis SA’s experimental vaccine against dengue protected healthy volunteers against all four strains of the virus in a study, bringing the drugmaker closer to providing the first vaccine against a disease that threatens 40 percent of the world’s population.
The vaccine protected all ... Read More

They're the overlooked viruses: Hepatitis B and C together infect three to five times more Americans than the AIDS virus does, and most don't know it.
In the next 10 years, these two liver-damaging infections will kill about 150,000 people in the U.S. alone, says a new report Monday from the ... Read More
H1N1 (swine flu) has killed 12,799 people worldwide since the virus first emerged, the WHO said on Friday, United Press International reports (1/8). According to the WHO, more than half of the H1N1-related deaths worldwide occurred in the Americas, China Daily reports (1/9).
"The WHO's tally ... Read More
Researchers from Brazil have estimated the growth timeline of a bacterium that causes orange juice spoilage during shelf life (approximately 6 months) and developed a safe and inexpensive filling, cooling, and storage protocol that inhibits bacterial growth and offers an alternative to other pro...

Scientists have devised a mathematical model that can predict how H1N1 virus infections can spread in an airplane during a transatlantic flight. Depending on the length of the trip, one individual who has H1N1 could infect two to 17 people during an airplane trip.
One reason for the interest ... Read More
Blasts of arctic air brought prolonged record-breaking low temperatures last week from the Midwest to the Southeast. In Florida, strawberries, beans, squash and other crops were at risk from extended freezes, but the greatest threat was to the multi-billion-dollar-a-year citrus industry. Get set... Read More
A SLIMY road planner has rearranged the UK's motorway network - and all in exchange for a hearty meal. A corrupt politician at work? No, it's Physarum polycephalum, a yellow slime mould normally found growing in piles of rotten leaves and logs.
Jeff Jones and Andrew Adamatzky, specialists in ... Read More
Knocking on door after door, thousands of volunteers fan out every month across southern and eastern Afghanistan, vaccinating children against polio, a disease eradicated almost everywhere else in the world.
Usually, the volunteers -- sent by the government and sponsored by United Nations age... Read More

The heavy eye make-up favoured by ancient Egyptians such as Cleopatra may have had medical as well as aesthetic benefits, French research suggests. The study, published in the journal Analytical Chemistry, suggests it helped to protect against eye disease.
The key appears to be lead salts con... Read More
Neisseria meningitidis, the meningococcus, is a bacterium that can cause diseases with high fatality rates, and there has therefore been considerable concern that, like other bacteria, it might become resistant to antibiotics. But now a study from Örebro University and Örebro University Hospital... Read More
As it turns out, children were not the only ones with visions of sugar plums dancing in their heads over this past holiday season. In a new research report published in the January 2010 issue of the Journal of Leukocyte Biology, a team of scientists from the University of Texas Medical Branch an... Read More
In this show, I report on four exciting stories: a new giant virus, bacteria that fight cancer, ancient microbial DNA, and using viruses to modify plants.
The aptly named Germ Terminator aims to conquer the world of germ-ridden shopping carts in supermarkets and other stores by using ultraviolet rays to kill bacteria on the carts' handlebars.
The origin of the Germ Terminator began when Danny Glenn, Fleet Cleaning Supply chief executive officer... Read More
A RIKEN-led research team has unraveled the molecular details of a key mechanism of the immune system in the gut. The work opens the way to new possibilities for developing versatile, inexpensive vaccines that are swallowed, rather than injected.
“The description of this molecular pathway fil... Read More
A bird flu scare has hit the Kaziranga National Park in Assam, a northeastern state of India, with carcasses of at least a dozen migratory Bar-headed Geese found in the sanctuary, officials said on Friday.
A park warden said at least seven geese were found dead on Friday. Five carcasses of th... Read More
