...work of Dr. Lars Olov Bygren in epigenetics referenced in your article would seem to nullify one of the icons of Darwinian evolution, Darwin's finches. Darwin noted that the bill length of finches changed depending on environmental conditions. Darwin explained this by natural selection. Other scientists have noticed that the bill lengths of those finches return to normal when conditions return to normal. Sounds like epigenetics and not Darwinian evolution. Darwin skeptics tend to agree that organisms can adapt (or evolve) within certain boundaries, but such organisms do not evolve into new species. Bygren's study of epigenetics would...
...story's complexities and keep the finger-pointing to a minimum. They pump up the tension by obliging John, like a thriller hero caught between the law and the bad guys, to battle both the long odds of finding a treatment and the fiery truculence of Ford's Dr. Stonehill. But while Ford growls and prowls like Darth Vader advancing on Han Solo, Fraser keeps the story anchored in reality. Meredith Droeger does too: as the Crowleys' afflicted daughter, she's a smart little bundle of fighting spirit...
While the NYU, Washington University and Harvard studies all used different approaches, their overall findings were remarkably similar. "The brain is trying to weave ideas together even when you don't think you are thinking of anything," notes Johns Hopkins behavioral neurologist and memory expert Dr. Barry Gordon. That's something to keep in mind the next time you catch yourself daydreaming in a meeting or idly surfing Facebook when you should be studying...
...pain on Greg Hadley's face. The senior from Colgate University, a two-time all-conference linebacker on the school's football team, is sitting in a Bedford, Mass., laboratory, staring at shattered brains of dead football players. On this Friday afternoon, Hadley has come to visit Dr. Ann McKee, a Boston University neurological researcher who has received a dozen brains donated from former NFL, college and high school players. In each one, it's simple to spot a protein called tau, which defines a debilitating disease known as chronic traumatic encephalopathy, or CTE. Common symptoms of CTE include sudden...
...goal is to prohibit head games. "The No. 1 thing: take the purposeful helmet hit out of football, for both blocking and tackling," says Dr. Robert Cantu, one of the country's premier concussion experts and a co-founder of Sports Legacy Institute. That goes for running backs as well. Too often, they make a conscious decision to lower their head into a defender, hoping the forward lean will give them an extra yard. That defender's natural reaction? Go head-on as well. What if running backs weren't allowed to intentionally lead headfirst? The NFL is at least...
