AP - A new swine flu strain that has killed as many as 68 people and sickened more than 1,000 across Mexico has "pandemic potential," the World Health Organization chief said Saturday, and it may be too late to contain the sudden outbreak.

AP - Mexico is contending with an outbreak of swine flu, suspected in the deaths of dozens of people and sickening perhaps 1,000. In the United States, at least eight cases have been confirmed with the infection, all of them in California and Texas; only one person was hospitalized. Here are some questions and answers about the illness:

AP - The schools and museums are closed. Sold-out games between Mexico's most popular soccer teams are being played in empty stadiums. Health workers are ordering sickly passengers off subways and buses. And while bars and nightclubs filled up as usual, even some teenagers were dancing with surgical masks on.

AFP - The United States will lead its world partners in the battle to end deaths from malaria by 2015, US Ambassador to the United Nations Susan Rice said in Washington Friday.

AP - Scientists have grown blood vessels for kidney patients from their own cells, making it easier and safer for them to use dialysis machines, a new study says.

AP - The nation's richest prize in medicine and biomedical research was awarded Friday to three immune system researchers for work that led to new treatments for rheumatoid arthritis and diabetes.

AP - At least 16 people — and possibly dozens more — have died from a swine flu virus in Mexico, and world health officials worry it could unleash a global flu epidemic. Mexico City closed schools across the metropolis Friday in hopes of containing the outbreak, and tougher measures were being considered.
