In her exploration of the biology and chemistry of physical exercise, Nicola Twilley introduces the reader to Couch Potato Mouse and Lance Armstrong Mouse. Both had been fed a diet consisting almost entirely of fat and sugar and got little exercise. But while Couch Potato Mouse was lethargic, with rolls of visible fat, Lance Armstrong Mouse was lean, taut and active in its cage. It had been fed a daily dose of GW501516 or “516”, a drug that, as Twilley puts it, “confers beneficial effects of exercise without the need to move a muscle.” Whether such drugs will ever prove beneficial for...Read more

Alex Honnold, the world’s greatest solo climber, doesn’t experience fear like the rest of us. He climbs to dizzying heights without a rope or protective equipment of any kind, shuffles across narrow sills of stone such as the “Thank God” ledge high atop the sheer granite face of Half Dome in Yosemite National Park.

But he agreed, and the result was a fascinating tour of the...Read more

In a trio of stories from China, Nepal and Tibet, Beijing-based freelancer Jane Qiu described how fossil finds in China are challenging ideas about the evolution of modern humans and our closest relatives; how rapid changes in Tibetan grasslands are threatening Asia’s main water supply and the livelihood of nomads; and how scientists are wiring up mountainsides in Nepal to monitor and forecast heightened landslide hazards in the wake of the devastating Nepalese earthquake in 2015. The judges praised Qiu’s initiative and in-the-field reporting skills. Her piece on...Read more

Amanda Gefter described the fascinating life of Walter Pitts, who was bullied as a child in Detroit and took refuge in the local library where he taught himself Greek, Latin, logic, and mathematics. He ran away from home at age 15, became a pioneer in neuroscience and cybernetics at MIT, and later became a withdrawn alcoholic. Pitts worked with Warren McCulloch, who was born at the other end of the economic spectrum in a family of privilege. "McCulloch and Pitts were destined to live, work, and die together," Gefter writes. "Along the way, they would create the first...Read more
