...didn't, because of unusually favorable ocean currents and weather patterns. "Early in the 2009 season it looked like we might be on the way to a record melt," says Julienne Stroeve, a research scientist at the National Snow and Ice Data Center, in Boulder, Colo., "but then winds spread the ice out, so the overall coverage ended up being greater than in 2007." Without those winds, in other words, 2009 might have set a new record for open water. But as it happened, ice cover in 2008 and 2009 rebounded significantly - but perhaps deceptively so.

Hugh Pennington, a microbiologist at the University of Aberdeen who has advised the British government on past public-health crises, says the WHO was obligated to raise the alarm as soon as H1N1's spread matched the medically accepted definition for a pandemic.

Hepatitis B is transmitted through blood or bodily fluids - spread through unprotected sex, blood transfusions, sharing of needles or contaminated tattoo or acupuncture instruments. Hepatitis C spreads only through infected blood. Patients with hepatitis B typically fight off the virus on their own, after which they retain lifelong immunity to the disease; however, about 6% to 10% of adults and children over five who are infected go on to develop chronic disease. (The numbers are much higher for younger children and infants who contract the virus.) Hepatitis C is more often a chronic infection, with a minority of patients experiencing...
...renowned evolutionary biologist Stephen J. Gould died at age 60 from lung cancer just 10 weeks after doctors found the tumor, which had already spread to his liver, brain, and other organs. His wife, Rhonda Roland Shearer, brought suit three years later, claiming that the lesion that became cancerous was already evident in an X-ray taken of Gould’s chest...
