Gates Donates $160 Million For Malaria Research

Microsoft chairman Bill Gates and his wife Melinda announced Sunday that they were donating $168 million to aid research into malaria, which kills more than 1 million people each year, most of them African children, the Associated Press reports.

The grant is the largest ever single donation made to combat malaria, which is transmitted by mosquitoes and is making a comeback in Africa. The problem: Strains of the disease have become resistant to treatment, including antibiotics, the AP says.

"I hope we bring a message of commitment and optimism," said Gates, who made the donation through the Bill & Melinda Gates Foundation.

The U.S. Centers for Disease Control and Prevention estimates that there are 300 million to 500 million cases of malaria each year.

Isabel's Legacy: 30 Dead, Millions Without Power

At least 30 people are dead in the wake of Hurricane Isabel, which knocked out power to some 6 million people from North Carolina to New York. As of Sunday, more than 2 million homes and businesses were still without power, affecting more than 5 million people, The New York Times reports.

Many were cleaning out refrigerators and freezers filled with spoiled food.

President Bush declared disasters in North Carolina and Virginia, pledging federal aid to both. State emergencies were declared by the governors of Delaware, Maryland, New Jersey, Pennsylvania, and West Virginia.

For those who have lost power, the U.S. Food and Drug Administration offers this advice:

  • Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature. The refrigerator will keep food cold for about four hours if it is unopened. Buy dry or block ice to keep your refrigerator as cold as possible if the power is going to be out for a prolonged period of time. Fifty pounds of dry ice should hold an 18-cubic foot full freezer for two days.
  • If you'll be eating your refrigerated or frozen meat, poultry, fish or eggs while they are still at safe temperatures, be sure they are thoroughly cooked to the proper temperature to assure that any food-borne bacteria that may be present is destroyed.
  • Wash fruits and vegetables with water from a safe source before eating.
  • For infants, if possible, use prepared canned baby formula that requires no added water. When using concentrated or powdered formulas, prepare with bottled water if the local water source is potentially contaminated.

7 Charged With Defrauding Medicare of Tens of Millions of Dollars

Seven people -- two of whom are doctors -- have been charged with defrauding Medicare of at least $46 million by filing claims for thousands of motorized wheelchairs that were either never delivered or not needed.

The U.S. attorney in Houston said the doctors and equipment dealers had submitted more than $84 million in phony claims during the past two years, the Houston Chronicle reports.

Motorized wheelchairs -- some of which can cost more than $5,000 -- are among the most expensive pieces of equipment that Medicare will purchase for patients, the newspaper reports.

"There were holes in the system. These holes were exploited," U.S. Attorney Michael Shelby said. "This was a relatively easy and quite lucrative crime to commit."

AP: No Evidence of Smallpox in Iraq

American scientists assigned to hunt out weapons of mass destruction in Iraq say there's no evidence that Saddam Hussein stockpiled smallpox, the Associated Press reports.

Fears of the deadly virus being used against American interests were among the reasons cited for the U.S.-led invasion of Iraq.

Among the only items found so far are disabled lab equipment and a laboratory covered in cobwebs, the wire service reports. In addition, Iraqi researchers interviewed by the American scientists have given no indication that they had ever worked with smallpox.

Following the Sept. 11, 2001, terror attacks, fears of a bioterror strike using smallpox led the Bush administration to order 500,000 military troops to receive the dangerous smallpox vaccine, and to order enough vaccine for the entire country.

President Bush himself was vaccinated against the disease, which kills about one-third of its victims, the AP reports.

IV-Drug Risk Increases With Age, Study Finds

Older men who inject drugs are up to six times more likely to die from the practice than are younger men, British researchers conclude from a new study.

Among 20,000 Scottish IV-drug users, men over 34 were two to six times more likely to die than were men under 25, according to the scientists at Cambridge and Strathclyde universities.

"The public health message of 'stop injecting' and 'never start injecting' are as important as ever," study researcher Prof. Sheila Bird tells BBC News Online."But we have shown that cessation of injecting, as a goal, might be particularly critical for older drug users."

The study appears in the Sept. 20 issue of The Lancet.

When It Comes to Diet, Better Late than Never

If you've wanted to diet for years but never quite found the drive or willpower, there still may be hope. A new study finds that lowering dietary intake later in life still reduces the likelihood of death -- at least in fruit flies.

The British study, published in the Sept. 19 issue of Science, found that fully-fed flies lived about 32 days, while flies on a restricted diet lived an average of nearly 50 days, HealthDay reports.

The restricted diet contained about 35 percent fewer nutrients than the fully-fed diet, according to researchers who led the study at University College London.

The researchers concede they don't know why restricting the diet had such a dramatic effect on mortality. They've hypothesized that dietary restriction increases life span because it slows down the damaging effects of processes, like oxidation, that occur as food is digested, HealthDay reports.
