Fish Oil Is No Snake Oil
Recent reports on the health benefits of fish oil sound almost too good to be true. The omega-3 fatty acids that it contains have been shown to reduce the risk of heart attacks and strokes and slow the formation of plaques in the arteries, and they may also lower blood pressure. Accordingly, the American Heart Association now recommends that healthy people eat fatty fish at least twice a week (individuals with heart disease should consume 1,000 milligrams of omega-3s per day and may want to discuss capsule supplements with their doctors). The latest studies go even further, demonstrating that the benefits of omega-3s extend beyond the heart and exploring exactly how these fatty acids do their good work in our bodies.

The Intellectual Property Fight That Could Kill Millions

Ngurah Rai International Airport in Bali is best known as a tourist hub, the bustling port of entry to a volcanic paradise. But when Indonesian authorities learned that a Mexican swine flu had gone global, that hub became a surreal microcosm of flu politics. Each arriving passenger was scanned for fever. A Dutch woman, apparently ill while in flight, was greeted by health workers in hazmat suits and whisked into quarantine while fellow passengers were spritzed with disinfectant. The woman was found to have nothing more than a bad sore throat, according to news reports, but that did not change a thing. The controversial head of the Indonesian Health Ministry, physician Siti Supari, quarantined sick foreigners at warp speed. Already embroiled in a battle royal with the world’s superpowers over another flu virus—the ultra-lethal bird flu—Supari did not have time to deal with a new enemy. She would do everything possible, she told her fellow citizens, to protect them from the new pathogen spawned by a pig.

The recent frenzy in Bali stood in notable contrast to the research paralysis that has gripped this tropical archipelago since late 2006, when Supari declared that flu viruses circulating in Indonesia belonged to her government alone. It was a bizarre, 21st-century twist on an age-old intellectual property argument. Developing nations had long fought passionately over plant and native human genes, but no one had ever before staked claim to microbes that birds could carry anywhere. Yet the 57-year-old health minister insisted she had cause: Rich Western nations were patenting the viral genomes, then using the information to create vaccines that were sold for profit to other Western powers while benefiting Indonesia not at all.

If Supari had stopped there, she might have garnered real support. But she ramped up the rhetoric, launching a barrage of fear bombs by accusing the United States of genetically engineering H1N1 (the swine flu virus) and H5N1 (the bird flu pathogen) as biological weapons. Wielding those charges, she flouted agreements with the World Health Organization (WHO), refusing to share samples from Indonesians infected with avian influenza—specimens the rest of the world desperately needs to track a virus on the move.

Bone/Tendon Hybrids Could Quickly Repair Injury
When quarterback Tom Brady tore a knee ligament last year, the New England Patriots got a rude lesson in the limits of modern medicine: Repairing injured ligaments, tendons, and cartilage is difficult, much trickier than mending a broken bone. When tendons—essential connectors between muscle and bone—are severed, surgical attempts to anchor the tendon to bone often fail because the materials are so different. The problem is akin to joining a rope to a cement wall.
