Solving the Overkalix Mystery By early 2000, it seemed clear to Bygren that the feast and famine years in 19th century Norrbotten had caused some form of epigenetic change in the population. But he wasn't sure how this worked. Then he ran across an obscure 1996 paper by Dr. Marcus Pembrey, a prominent geneticist at University College London...
...calorie claims in restaurants, which means it's up to the states to handle the job - with the predictable patchwork results. "It really is the Wild West when it comes to this," says Roberts. "And when state inspectors do visit, they have other issues to worry about - like making sure there are no mouse droppings in the kitchen." (See how some people are getting paid to lose weight...

"We want to see at least three transits to be absolutely sure," says Borucki...
...funny thing is, scientists have known about epigenetic marks since at least the 1970s. But until the late '90s, epigenetic phenomena were regarded as a sideshow to the main event, DNA. To be sure, epigenetic marks were always understood to be important: after all, a cell in your brain and a cell in your kidney contain the exact same DNA, and scientists have long known that nascent cells can differentiate only when crucial epigenetic processes turn on or turn off the right genes in utero...
...standoff reminded both sides that their economic relationship was far too important to allow a little geopolitical competition to get in the way, and that same economic relationship - with an ascendant China now bankrolling much of a trillion-dollar U.S. budget deficit - continues to shape the relationship under Obama. Sure, Obama's realpolitik has seen him refrain from some of the largely symbolic irritants to the U.S.-China relationship that Bush was willing to risk, such as meeting with the Dalai Lama or going to church in Beijing to express solidarity with Chinese Christians, but then, Obama's America...
