...France's ostreiculture industry since last month: the discovery that 40% to 100% of oysters aged 12 and 18 months being raised in France's Atlantic cultivation beds had died. The reason, officials at the French Institute for Research Into Use of the Sea (Ifremer) say, is Oyster Herpes Virus type 1 (OsHV-1). That virus, has proliferated along France's Atlantic coast due to a mild winter and abundant rains that allowed ocean water to remain warm, scientists believe. Those same conditions have also created an abundance of plankton - a cornucopia of nutrition that the shellfish have gorged...
...abundance of herpes and plankton on the Atlantic coast - and which contributed to an explosion of jellyfish in Mediterranean waters have also caused a proliferation of Vibrio splendidus bacterium. The effects of that bacteria left younger oysters both more vulnerable to herpes infection, and less capable of battling the virus as it killed them. Scientists fear that as waters heat up thanks to global warming oysters may regularly face such conditions in the future, disrupting France's annual oyster production of 120,000 tons - the largest in Europe and fourth biggest in the world...
...death toll from the 11,713 so far to 179,000. Increasingly, AIDS will afflict heterosexuals, and it will spread fast outside of such hard- hit cities as San Francisco and New York. An estimated 1 million to 1.5 million Americans have been exposed to the AIDS virus, and up to 30% of these could develop the syndrome...
...health officials had planned - until the Merck vaccine failed last fall. In a trial of 3,000 volunteers, Merck's vaccine appeared to increase risk of HIV infection, a phenomenon that researchers later attributed to the vaccine's delivery system - pieces of HIV were piggybacked onto a common cold virus and ferried to the body's immune cells. It turned out that the people who received the vaccine and who ended up with the highest rates of HIV infection following injection were also those who had high levels of antibodies to the cold virus, thus negating any immune-boosting effects...
...government's trial of its vaccine, PAVE, for Partnership for AIDS Vaccine Evaluation, was to have included only people with low levels of cold-virus antibodies, but Fauci argues that any information that could have been gleaned even from the smaller trial might not have proved useful. "Even pared down, the trial was too big," he says, "and was asking too many questions before we even knew if this thing worked. So I asked them to go back and give me a slimmer study that asks the question 'Does it work...
