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

The bacterium Campylobacter jejuni is a major cause of food poisoning in humans. It is normally transmitted from contaminated chicken meat, as it is frequently found in the intestines of chickens, where it apparently does not result in any symptoms. Campylobacter jejuni is well adapted to life i... Read More
A group of Danish scientists has developed a method to recycle valuable metals that would ordinarily have to be mined and refined before ending up in chemists’ hands. Their discovery means that the metals could be sourced instead from electronic waste or polluted water and soil.
The researche... Read More
South Korean health authorities are reporting the country's first two cases of a new gene that makes bacteria resistant to most antibiotics.
Health official Lee Yeong-seon says experts detected the gene, known as NDM-1, in two people. The two patients have been hospitalized for a lengthy time... Read More
A team of UCSF researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations.
The work builds into cells the same logic gates found in electronic computers and creates a method to create circuits... Read More
Influenza is a crafty opponent. Just when researchers think they might know where it's headed next, it mutates. New strains form constantly, allowing the virus to evade detection by the human immune system, and these new strains can turn into pandemics with little to no warning. In 1918, the H1N... Read More
Hoku endured some rough days before he died last spring. Three dogs chased him off one of his resting beaches, and he battled a minor tsunami that left him wedged between a pair of boulders in a lava field far from shore.
Observers noticed him looking thin in the few months before fishermen f... Read More
All life on Earth - from microbes to elephants and us - requires the element phosphorus as one of its six components.
But now researchers have discovered a bacterium that appears to have replaced that life-enabling phosphorus with its toxic cousin arsenic, raising new and provocative questio... Read More
Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in deep ocean water, a finding that could dramatically change ideas abo... Read More
As Haiti's deadly cholera epidemic spreads, it may seem irrelevant to ask where the disease came from. The World Health Organization certainly thinks it is, describing the question as "unimportant".
That could not be further from the truth. Haitians themselves care deeply about how their coun... Read More
More bad press for free radicals. Now it seems that too many of them can impair the mouse immune system, making them unable to fight off flu.
The finding could shed light on the cause of many mysterious human immunodeficiency disorders, such as severe combined immunodeficiency (SCID), says Fr... Read More
