Americans are all for government efforts to get them to eat more healthfully, as long as they don't feel like they're being bullied into it. That's what people said in a new survey about government efforts to influence how we eat, like New York City's ban on supersized sodas.
In the past decade, state and federal governments have launched dozens of new laws and programs to promote healthful eating and exercise. They've put a lot of effort into measuring what works, but surprisingly little effort into finding out what the people at the receiving end think.
Washington State Rep. <a href="http://houserepublicans.wa.gov/ed-orcutt/">Ed Orcutt</a> has apologized for saying "the act of riding a bike results in greater emissions of carbon dioxide from the rider," after an email with a bike shop owner sparked criticism.

Climate change will make commercial shipping possible from North America to Russia or Asia over the North Pole by the middle of the century, a new study says.
Two researchers at the University of California ran seven different climate models simulating two classes of vessels to see if they could make a relatively ice-free passage through the Arctic Ocean. In each case, the sea routes are sufficiently clear after 2049, they say.
