James Cameron: nature filmmaker? It's a title even the director himself - a self-described tree hugger - might not have expected. After all, in his budget-busting moviemaking career, Cameron has engineered a planet-killing nuclear holocaust (The Terminator), created acid-blooded extraterrestrials (Aliens) and made a villain out of an iceberg (Titanic). His latest film, Avatar, the record-setting sci-fi epic filmed mostly with motion-capture cameras and computer graphics, is about as unnatural as a movie...
Harvard Medical School Professor Jon Clardy teamed with researchers in the department of biological chemistry and molecular pharmacology to pinpoint the amino acid proline—a component of hemolymph, or insect blood—as the trigger for the transformation of roundworm bacteria from dormant to virulent, eliciting comparisons of the bacteria to Dr. Jekyll and Mr. Hyde...
...reads like a horror story. Priklopil barely fed her during her captivity, taking pleasure in showing her a plate full of food and then only giving her a small amount. She was also banned from showing any emotion. "He forbade me from crying because he was worried the salt acid could damage his tiles," she says. "When I did cry, as I couldn't help it, he grabbed me on my neck, choked me and he pushed my head under the tap in a basin." Eventually, Kampusch says, Priklopil allowed her into the main part of the house...
...fatty-acid craze threatening our ecosystem? The best omega-3 source is oily fish like salmon, mackerel and sardines. Environmentalists fear that some species - especially a small filter feeder called menhaden, which plays a critical role in the aquatic food chain - are being overfished for oil supplements. Bigger fish prey on menhaden, which eat omega-3-rich algae and in doing so clean the ocean waters off the Atlantic and Gulf coasts. By filtering up to 7 gal. (about 26 L) per min., menhaden help prevent oxygen-depleting algal blooms that lead to underwater dead zones...
...declining menhaden population isn't the only concern swimming around fish-based omega-3 supplements. Mercury consumption is another, as are the needs of vegetarians. The good news there is that plant sources like flaxseed and canola oils have one of the omega-3 fatties, alpha-linolenic acid (ALA). The bad news is that they don't contain docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA), the more important omega-3 nutrients. Our bodies can convert ALA into DHA and EPA, but the process is limited and slow. (See "The Year in Health 2009: From...
