Every day, it seems, new research “raises hopes” that stem cells will cure a new disease. I myself have written about the enormous potential of stem cells more times than I can count. Since stem cells can transform into any type of cell in the body, they might become a source of replacement cells for […]

I was teetering along the concrete track at about 5 miles per hour, a pathetic speed that nonetheless significantly exceeded my comfort zone. “Baseball slide,” barked a blonde pixie in a tiny pink skirt and massive black TSG kneepads over leopard-print tights. I tensed my core, gingerly lowered my left knee, and on impact, slipped […]
Most archaeologists I know have a soft spot for Indiana Jones. They might not admit it. They might grimace at the famous bullwhip and guffaw at all the suspension-bridge antics over crocodile-infested waters. But despite that, or perhaps because of it, Indiana Jones often captures something from a defining moment in their lives. It reminds […]
Since the launch of the Global Polio Eradication Initiative in 1988, intense vaccination campaigns have dramatically reduced the number of cases of polio worldwide. Between 1988 and 2000, the number of polio cases dropped 99 percent — from 350,000 to just 3,000. But the polio eradication effort appears to have stalled out. Despite an investment […]
I am a bit of a Civil War nerd. I inherited this interest from my dad. Together we have visited many of the Civil War’s top landmarks (we’ve even paid our respects to Stonewall Jackson’s left arm). But for all of the time I’ve spent on battlefields, I never gave any thought to the landscapes […]
I’ve kept an eye on neutrinos ever since I heard, back in the mid-1980’s, that not enough of them were coming out of the sun; this sounded serious. It turned out that the sun was behaving itself but the neutrinos weren’t. On its way out of the sun, any given neutrino was changing into three […]
Some scientists make great discoveries. Some scientists provide the opportunity for other scientists to make great discoveries. Let us now praise one not-so-famous man. Victor Blanco assumed the directorship of the Cerro Tololo Inter-American Observatory (CTIO) in June 1967, just five months before the observatory opened. CTIO, a collaboration between U.S. and Chile, was an […]
I’ve been thinking a lot about resilience lately, that ineffable quality of being able to withstand trickling insults and outright catastrophe. It characterizes the Japanese ability to remain civil and calm throughout their ongoing weeks of dread, and the ability of some natural systems to bounce back after even the most egregious of impacts. It […]
