AI2. SATURDAY. APRIL 21, 2001 HEALTH & SCIENCE THE SALINA JOURNAL • GENETIC RESEARCH Europeans linked to few Africans C-sections make comeback Genetic tracking finds linl< to only a few hundred Africans By The Associated Press EDINBURGH, Scotland — Modern Europeans, and maybe populations in other parts of the world, are descended from no more than a few hundred Africans who left their homeland as recently as 25,000 years ago, new research suggests. The findings, reported at the start of a conference of the Human Genome Organization, the international collaboration re­ searching the genetic makeup of the human race, provide the first estimate of how many people founded Europe. They are also a blow to the theory that modern humans evolved simultaneously in Africa, Europe and Asia from multiple early humans. "I think this certainly rules that out, at least in respect to Europe," said study leader Eric Lander, director of the Whitehead Institute/Massachusetts Institute of Technology Center for Genome Research. "We're not sure whether this was just the founding of Europe or T STAPH INFECTIONS Scientists decode killer staph gene Scientists may be able to develop better treatments By The Associated Press LONDON — Scientists have deciphered the genetic code of staph, a common but particularly dangerous germ that can be deadly for hospital patients and is becoming increasingly im- mtme to drugs. Japanese scientists report in The Lancet medical journal the first genetic blueprint of the bacterium Staphylococcus aureus. Researchers hope the information will help them develop better ways of fighting staph, one of the more notorious superbugs. In decoding the genes of two tough-to-treat strains of staph, the scientists from Juntendo University in Tokyo discovered five new classes of genes that produce potentially lethal toxins and 70 new genes that determine how virulent the germ is. Experts say the findings are a major contribution to the understanding of how antibiotic resistance develops in the parasite. "These (genes) ... may become possible targets for the design of novel therapeutic agents as well as vaccines," said Dlawer Ala'Aldeen, a bacteriologist at the University of Nottingham Hospital in Nottingham, England, who was not involved in the research. Staphylococcus aureus is considered the most successful of all bacterial germs because it produces such a wide range of infections in so many people. It is the leading cause of infections acquired in hospitals worldwide. whether, in fact, this small bottleneck represents all the people leaving Africa." Lander's study involved comparing about 300 chromosomes from people in Sweden, central Europe and Nigeria. The differences in the genetic pattern between the European and African chromosoines revealed how long ago Europeans left Africa and about how many there must have been. The pattern showed the Europeans were descended from fewer ancestors than the Africans — an evolutionary bottleneck, Lander said. "It's hundreds, not thou- T ANTARCTICA sands," Lander said. The Nigerian chromosomes had been weU-shuffled-around, which indicates a wide gene pool and a long breeding history, while the European chromosomes had long stretches of un- shuffled genetic material, indicating a much smaller number of chromosome types entering the mix. Lander said the findings had much broader applications. "We are going to be able to do this throughout much of the rest of the world. The data will be able to rule it in or out for the other populations very quickly," Lander said. By Pittsburgh Post-Gazette C-sections are making a comeback, reversing the course set in the early 1990s, when public health officials campaigned to increase the rate of vaginal births after Caesareans. C-sections cost more than vaginal deliveries, are thought to carry a higher risk of complications for the mother and require longer hospital stays. But recent publications in medical journals have pointed out small risks in CaesareanS; Those warnings come at a time when medical malpractice premiums are on the rise. "It is simply not a secret that there are trial lawyers out there and having babies is a big issue," said Marc Volavka, executive director of the Pennsylvania Health Care Cost Containment Council. Ailing Americans to leave Antarctic station By The Associated Press WELLINGTON, New Zealand — A rescue flight will evacuate four Americans who need medical attention from an Antarctic research base, officials said Friday The four, whose identities and conditions were not released, will be flown out of McMurdo Base on the Antarctic coast by a Royal New Zealand Air Force transport plane Monday, said Vivienne Allan of New Zealand's Antarctic agency In a separate rescue, two Canadian planes were waiting in Chile for weather conditions to improve to airlift out a sick U.S. doctor from the Amundsen-Scott South Pole Station in the Antarctic. Dr Ronald She- menski, 59, the station's lone physician, recently passed a gallstone and has the potentially life-threatening condition known as pancreatitis. At the McMurdo Base, freezing temperatures and only half an hour of light a day mean the aircraft will spend just an hour on the ground as it loads the four Americans and refuels for the seven-hour return flight to Christchurch, New Zealand. The plane will arrive with two replacement staffers, who will spend the winter at McMurdo, the main U.S. scientific base in Antarctica.
