Alaskan king salmon are getting sick, and experts have named a culprit: global warming. Marine ecologists say that a rise in "white spot disease" is tied to a 3-decade trend of higher temperatures in the Yukon River, the Los Angeles Times reports. With cold-temperature barriers melting, parasites and bacteria are moving north—and threatening Alaska's prized salmon stock. More »

Chronic ailments such as heart disease have become the top causes of death around the world, Reuters reports. Infectious disease, such as tuberculosis and AIDS, has traditionally been the planet's number-one killer. But new World Health Organization stats show noncommunicable conditions, many of which are associated with a Western lifestyle, are killing more people, and the numbers are projected to continue climbing.

Stagnant pools bursting with mosquitoes have become a byproduct of the housing crisis, turning into breeding grounds for diseases like West Nile virus. But, the Wall Street Journal reports, there is a solution: Gambusia affinis , a natural predator, also known as the mosquito fish, that's hardy enough to police abandoned watering holes from Florida to California.

Emergency supplies for some 1.5 million Burmese desperately in need of help are ready to be flown into the cyclone-stricken regions—but the military junta is still blocking delivery. Only two UN planes have been allowed to land in Burma. Secretary General Ban Ki-moon tried unsuccessfully to telephone Burma's top general to make a personal appeal to allow more relief supplies to get through, reports the Washington Post . More »

Saddam Hussein worried about catching AIDS and other venereal diseases during his US captivity, the Daily Mail reports. He even told guards not to dry their clothes on his laundry line. "I explained to them that they are young and they could have young people's diseases," Saddam wrote in prison diaries that were published today by a pan-Arab newspaper. More »

The outbreak of a deadly virus in China hasn’t peaked yet—but it won’t affect the Beijing Games, a World Health Organization rep said. “I don't see it at all as a threat to the Olympics or any upcoming events,” he noted. Enterovirus 71 has killed 24 children and infected thousands, the Guardian reports. But the highest volume of cases is usually seen in June and July, WHO said. More »

Measles, once nearly eradicated in the US, appears to be regaining a foothold. The CDC reports at least four outbreaks under way, with at least 64 cases in nine states—the most since 2001. The new cases probably originated in other countries and incubated in pockets of non-immunized US children, the Washington Post reports. If people continue to shun vaccines, large-scale outbreaks are possible, the CDC says. More »

The world must take action now to end malaria deaths—currently at 1 million per year—by 2010, UN chief Ban Ki Moon said today. "We have the resources and the know-how, but we have less than 1,000 days" to meet the goal, said Ban on the first World Malaria Day. The main push will be to provide bed nets and sprays to all of Africa, BBC reports. More »

The loss of biodiversity on Earth will seriously hamper efforts to cure human disease, AFP reports. Researchers at the UN-backed Business for the Environment conference highlighted undiscovered cures for pain, infections and even cancer that risk being lost forever if humans fail to reverse the widespread extinction of thousands of species caused, in large part, by climate change.

Drug-resistant strains of tuberculosis are at the highest levels disease experts have ever seen, warns the World Health Organization. A survey of 81 countries found that levels of multi-drug resistant TB and even hardier, almost untreatable TB were much higher than expected, reports the BBC. Urgent action is needed to avert a health catastrophe, the WHO cautioned. More »

Federal disease experts have launched an investigation into the outbreak of a mysterious skin condition that causes a stinging or crawling sensation, confusion and fatique, USA Today reports. Cases of Morgellons disease are on the rise, especially in California and Texas. The condition is so little-known that it was only named in 2002, after a similar condition reported  in the 17th century. Some 11,000 families, several with more than one member affected, have registered with the Morgellons Research Foundation More »

The first drug approved by the FDA to treat fibromyalgia is raising questions, but not the typical ones about whether the medication works. They're questions about whether the disease even exists. Lyrica sales are up and climbing, but critics say giving a name to the chronic pain that characterizes fibromyalgia lends the diagnosis undeserved legitimacy, the New York Times reports. More »

Disease-carrying insects may have contributed to the extinction of the dinosaurs around 65 million years ago, entomologists write in a new book. Scientists found malaria and other parasitic pathogens in insects preserved in amber, and the same parasites were found in fossilized dinosaur waste, the Guardian reports. New plants, pollinated by insects, forced the herbivores to adapt their diets or starve, the book also suggests. More »

A genetic mutation that increases the risk of breast cancer has been linked to Hispanic and young black women, according to a new study. The findings could lead to changes in screening, the San Jose Mercury News reports. In the survey of 3,181 women with breast cancer, 16.7% of black patients under 35 and 3.5% of Hispanic patients had the mutated gene, compared with 2.2% of white patients. More »

The pace of human evolution switched to the fast track when people began forming agrarian societies 10,000 years ago, researchers have discovered. Scientists had theorized that evolution would slow as challenges to survival waned, but the opposite appears to be the case with changes occurring surprisingly quickly, the Los Angeles Times reported.

A new British company has developed a home DNA test that determines whether customers are genetically predisposed to ailments such as breast cancer, heart disease, obesity, and osteoporosis. Users scrape a cheek with a swab, sign a special waiver if they want to know results even for incurable diseases, such as Alzheimer's, and send it off. The results come back in the mail. More »

The AIDS virus reached America through Haiti, not directly from Africa, and far earlier than has been suspected—the 1960's, not the early 1980's, researchers have discovered. Scientists analyzed 25-year-old blood samples and used what they know of the virus' mutations to construct a rough timeline of the progression of the disease, according to the study in the Proceedings of the National Academy of Sciences .

The White House halved prepared testimony the CDC director gave to a Senate committee this week, zapping sections about diseases that might result from global warming. A Bush spokeswoman said the speech was not “watered down,” the AP reports, but sentences such as “scientific evidence supports the view that the earth’s climate is changing” were excised. More »

The latest E. coli outbreak, which toppled Topps Meat and led to millions of recalled burgers, has stumped health agents. Muckrakers blame feedlots and abattoirs, saying bad animal diets increase infections when the meat mingles with innards, but others aren't so worried: "The reality is if you cook the meat you’ll never have a problem," says one industry consultant.

Researchers have developed a test that can identify bird flu in just 28 minutes, according to a study published this month in Nature Medicine . If bird flu mutates to a form readily passed among humans, rapid testing could be critical in identifying and containing an outbreak in its early stages. Current tests take between several hours and several days. More »
