...repeatedly devastated by hurricanes, Losos has produced some of the only empirical scientific evidence documenting evolution.“Darwin got one thing particularly wrong,” Losos said. “He said that evolution had to occur very slowly.”In fact, Losos has proven that evolution can occur very rapidly and that lizards will adapt to different environments at observable speeds. Thus, according to his research, evolutionary biology can be an experimental science.Losos has published about 125 scientific articles—over a dozen in just the journals Nature and Science?...
...believe that large cohort studies are a proven design that will serve African public health, and could also yield information relevant to the chronic disease epidemic in the US. The bold African Cohort Initiative aspires to fill this knowledge gap, and seeks equally visionary funders to bring studies that have enormously benefited wealthy countries to Africa. The time for action is now, before the problem escalates, so that results can guide successful prevention programs...
...trans people, the markers of identity can be extremely multifaceted. One friend transitioned from female to male in the past year, seemingly in real time on Facebook: Lucy became Andy and it said so right under his picture.

NICE uses a metric called "quality-adjusted life year," or Qaly, which grades a person's health-related quality of life from 0 to 1. Say a new drug for a previously untreatable condition comes on the market and the drug is proven to improve a patient's quality of life from .5 to .7 on the scale. A patient on the drug can expect to live an average of 15 years following the treatment. Taking the new drug thus earns patients the equivalent of three quality-adjusted life years (15 years multiplied by the .2 gain in quality...
...said. While the Crimson performed well in the most crucial part of its season in late spring, Harvard also began its year in impressive fashion with nine top-three team finishes from mid-September through mid-November. Despite the grueling schedule that runs throughout the academic year, Harvard has proven itself well-conditioned to compete on a national scale. The Crimson can expect trips to nationals in the coming years, as most of the team remains intact next season. “We only lose four girls [and two men] next year,” Powers said...
