...their study, Olowokure and his team counted 4,445 infections (excluding HIV) reported to 19 clinics in the region. From 1996 to 2003, total cases of chlamydia, genital herpes, gonorrhea, syphilis and genital warts among people over 45 increased 127%, from 344 cases in 1996 to 780 in 2003. Rates of STDs increased in patients under age 45 as well, by 97%, during the same time period. In the U.S. the most recent Centers for Disease Control and Prevention figures - which include prevalence of syphilis, chlamydia and gonorrhea - reflect relatively stable rates of infection in people ages 55 and older...
...boast funds valued at more than $1 billion. Even Britain's wealthiest universities are poor by comparison. The central endowment fund at Oxford is about $1.3 billion, and Cambridge's stands at roughly $2 billion. (The universities' individual colleges - Oxford has 39, Cambridge 31 - separately hold endowments worth a total of $11 billion.) At London's Imperial College, one of the world's best for scientific research, funds amount to around $115 million; and the endowment at the London School of Economics (LSE) is worth some $110 million. Over the last 50 years in Britain, says Richard, who was Yale...
...calculate that the risk for lung cancer probably returns to that of a nonsmoker somewhere between 10 and 15 years after smoking cessation. (We have less data on the [other smoking-related cancers].) But the risk that people have for smoking-related diseases is directly related to the total number of cigarettes they've smoked in their life. We measure that with something we call "pack-years": that's the average number of packs per day multiplied by the number of years they've smoked. The greater the pack-years, the greater the risk. When you're getting up around...
Researchers at Stanford University report that they may be able to make that decision easier. After analyzing the dozens of factors that fertility specialists consider when helping couples conceive, the Stanford researchers whittled down the list to the four most powerful predictors of an IVF pregnancy: the total number of embryos that a couple produces during a cycle, the number of embryos that survive to the eight-cell stage, the percentage of embryos that stop dividing and a woman's level of the follicle-stimulating hormone. What surprised the study's authors was that these measures appeared to be more...
...this story, approximate endowment returns were calculated from data on the monthly values of "endowment units" that Harvard entities can purchase just as investors buy shares of a company's stock. Changes in unit value for the past decade have tracked changes for Harvard's total endowment over the same periods, but lag overall growth by approximately two percent each year...
