Nonchemical treatment systems are touted as environmentally conscious stand-ins for such chemicals as chlorine when it comes to cleaning the water-based air-conditioning systems found in many large buildings. But a recent study by University of Pittsburgh researchers suggests that this diverse c... Read More
The World Health Organization is shifting its position in favor of vaccinating against cholera, acknowledging a growing clamor for ways to slow Haiti’s outbreak.
So far, the cholera vaccine has seen little use in Haiti, where the disease has killed more than 2,000 people and is still spreadi... Read More
Increasing antiviral resistance among certain influenza viruses and a lack of alternative antiviral treatment options have raised public health concerns, according to data from two new studies published in the Journal of Infectious Diseases.
Although the spread of influenza strains with resis... Read More
This episode: Bacteria form electric nanowires!
How would you like the battery in your smartphone to last ten times longer? It would be great wouldn’t it? No charging for a whole week, talking for hours safe in the knowledge you still have a few days charge left and still juice left to play Angry Birds every lunch time.
It’s the kind of ba... Read More
An international team of scientists, which includes researchers from Virginia Tech, has cracked the genetic code of a plant pathogen that causes downy mildew disease. Downy mildews are a widespread class of destructive diseases that cause major losses to crops as diverse as maize, grapes, and le... Read More
The H1N1 swine flu virus which swept the globe last year has returned to Britain with 10 people dying in the last six weeks, health officials said Saturday.
Britain's Health Protection Agency said the 10 deaths had occurred in adults all under the age of 65, most of whom had underlying health... Read More
A new study has revealed that there are greater similarities between the DNA repair systems of bacteria and humans than previously thought.
The University of Bristol researchers have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used... Read More
Last week, amid much fanfare, scientists reported they had found an organism that — unlike all previously observed life on Earth — was able to do without phosphorus and use the normally deadly element arsenic in its place.
This week, skeptical scientists expressed serious concerns about the d... Read More
With all the hubbub over tax breaks and unemployment, it's interesting that flu shots turned up on the president's radar this week. President Obama signed a proclamation declaring this week as National Influenza Vaccination Week.
As this proclamation says: "Last year, as the world prepared fo... Read More
Frogs across Australia and the US may be recovering from a fungal disease that has devastated populations around the world.
"It's happening across a number of species," says Michael Mahony at the University of Newcastle in New South Wales, who completed a 20-year study of frogs along the Grea... Read More
Leading public health officials and researchers are calling for a crash vaccination campaign against cholera in Haiti and neighboring countries.
A vaccine is needed, they say, to control what researchers say is a more lethal strain of cholera circulating widely in Haiti and starting to affect... Read More
A parasitic fungus called Blumeria graminis (green) colonises the insides of the living epidermal cells of a barley plant Hordeum vulgare (outlined in yellow) in this epifluorescence microscopy image by Pietro Spanu of Imperial College London.
Blumeria is a type of powdery mildew - fungal dis... Read More
Star Trek:The Next Generation may have been prescient when they dreamed up the Borg -- living organisms that had been transformed into a hive computer mind. Indeed, many biology and genetics researchers today are hoping to transform bacteria into drones, forming a biological supercomputer of th... Read More
Nothing like a public health crisis to put a new technology through its paces.
Scientists on Thursday said they used new technology to rapidly sequence the genome of the cholera bacterium that has killed more than 2,000 people in Haiti and sickened nearly 100,000.
The analysis confirmed on... Read More

One day in 2004, a 29-year-old man with a terrible stomach problem stepped off a plane from the United States in Thailand. He wasn't there for the sights, or the food, or the beaches. He had traveled thousands of miles for worms -- parasitic worms whose eggs he intended to swallow by the thousan... Read More
Influenza researcher Peter Palese visited yesterday and spoke about “Pandemic influenza: Past and Future”. A key part of his talk was a review of his efforts to produce a universal influenza vaccine which protects against all strains. He used the following graph to make the point that when influ...

The strain of cholera currently sweeping through post-earthquake Haiti originated in South Asia, conclude scientists who did a rapid genetic analysis of bacteria collected from Haitian patients. The finding supports the notion that the cholera bacteria fueling the outbreak arrived on the island ... Read More
