Scientists have uncovered a novel mechanism by which Salmonella bacteria infect humans and say the discovery could potentially be exploited to kill cancerous cells.
In an article published in the journal Science, researchers from the University of Glasgow and the University of Massachusetts M... Read More
The spread of lethal diseases from animals to humans has long been an
issue of great concern to public health officials. But what about
diseases that spread in the other direction, from humans to wildlife?
A multidisciplinary team of researchers at the University of Georgia
(UGA) has jus... Read More
Novartis AG (NVS) Monday said it will submit meningococcal disease vaccine Menveo in the U.S. and elsewhere to treat children aged two months and older after fresh late-stage trials showed the drug to be effective to treat infants.
Menveo, which already passed the regulatory hurdle in the U.S... Read More
Cholera, a virulent illness that comes on quick and can be fatal mere hours after symptoms appear, kills more than 100,000 people a year.
The infection is characterized by chronic diarrhea, rapidly leading to life-threatening dehydration and electrolyte imbalances. And because nearly three-qu... Read More
The same taste buds we have on the tongue to detect bitterness also exist on lung muscle so that the airways can "taste" dangerous illness-causing bacteria, according to new research published Sunday that could lead to better treatments for respiratory conditions.
When the taste receptors in ... Read More
On episode #104 of the podcast This Week in Virology, The entire TWiV family reviews the latest ideas about colony collapse disorder of honeybees, and resurgence of monkeypox in Africa.

The H1N1 swine flu virus might be mutating. A new form of the virus has started to predominate in Australia, New Zealand and Singapore according to a new report in Eurosurveillance.
The World Health Organization (WHO) says more study will tell whether the new strain is deadly and whether the ... Read More
A potentially lethal germ resistant to even the most powerful antibiotics is spreading fast in Chicago health-care facilities, new research suggests.
This latest “superbug” is formed when common bacteria produce an enzyme called Klebsiella pneumoniae Carbapenemase, or KPC, that makes them res... Read More
A variant of last year's pandemic influenza linked to fatal cases carried a mutation that enabled it to infect a different subset of cells lining the airway, according to new research. The study, to be published in the Journal of Virology, suggests that the mutant virus could have impaired the l... Read More
A never-before detected strain of virus that killed more than one-third of a monkey colony at a U.S. lab appears to have 'jumped' from the animals to sicken a human scientist, researchers report.
Although it's an unusual move for that type of virus and does warrant further monitoring, the res... Read More
There are some major evolutionary jumps that seem to have occurred only once. Eukaryotic cells contain membrane-enclosed structures to perform different functions, and they comprise all forms of multicellular life on Earth. They arose from prokaryotes only once in four billion years, and no prok... Read More
The Terminator. The Borg. The Six Million Dollar Man. Science fiction is ripe with biological beings armed with artificial capabilities. In reality, however, the clunky connections between living and non-living worlds often lack a clear channel for communication. Now, scientists with the Lawrenc... Read More
By any other name, the Anopheles gambiae mosquito would still bear—with its tiny buzzing wingbeats—the deadly threat of malaria, which can be passed to humans in a single blood-sucking bite. But what if this species were to split in twain?
Two new studies, published online October 21 in Scien... Read More
It's common knowledge that the U.S. no longer produces enough scientists and engineers to keep pace with the rest of the world. Now, the organizers of the USA Science & Engineering Festival are doing something about it, with a two-week, nationwide extravaganza for left-brain-leaning young people... Read More
Social media consists of Internet technologies that allow users to create and share content, and to foster dialogues among other users. Examples include software applications for communication (blogging, social networking, discussion forums), collaboration (wikis, social bookmarking), and multim... Read More
Biofilms: whether it’s coating the opening of a geyser in Yellowstone Park or lining the surface of your shower curtain, the signaling molecule cyclic diguanylate (c-di-GMP) essentially tells bacteria in these ecosystems when to get-up-and-go or when to settle down and get comfortable. By regul... Read More
America is angry: about lost jobs, the ballooning deficit, and the apparent failure of massive "stimulus" spending to improve the lot of citizens hammered by the worst economic slump since the 1930s. Above all, Americans are angry with politicians who promised change for the better.
As the co... Read More
Broccoli, a vegetable already renowned for its cancer-fighting potential, might now become an even more potent enemy to tumors everywhere. Scientists have made a key discovery into how the cruciferous veggie's compounds are used by the body, meaning that a little tinkering could make its protect... Read More
Feeling stuffy and miserable? Forgot your flu jab this year? What you need is a vaccine that will stop flu once and for all – and prospects for one have just got brighter.
A protein touted as flu's Achilles' heel when it was discovered last year has now been tested as a vaccine, and it worked... Read More
