Those who wonder why large parts of North America seem to be skipping winter have a new answer in addition to climate change: big city life.
A study, published in the journal Nature Climate Change, found that the heat thrown off by major metropolitan areas on America's east coast caused winter warming across large areas of North America, thousands of miles away from those cities.

We're in contact with uncontrolled synthetic chemicals
In testimony before a Senate subcommittee, Ken Cook spoke passionately about 10 Americans who were found to have more than 200 synthetic chemicals in their blood.
The list included flame retardants, lead, stain removers, and pesticides the federal government had banned three decades ago. "Their chemical exposures did not come from the air they breathed, the water they drank, or the food they ate," said Cook, president of the Environmental Working Group, a national advocacy group.
Is PTSD Contagious?
It's rampant among returning vets—and now their spouses and kids are starting to show the same symptoms.
Brannan Vines has never been to war. But she's got a warrior's skills: hyperawareness, hypervigilance, adrenaline-sharp quick-scanning for danger, for triggers. Super stimuli-sensitive. Skills on the battlefield, crazy-person behavior in a drug store, where she was recently standing behind a sweet old lady counting out change when she suddenly became so furious her ears literally started ringing.
DNA pioneer James Watson takes aim at "cancer establishments"
A day after an exhaustive national report on cancer found the United States is making only slow progress against the disease, one of the country's most iconic - and iconoclastic - scientists weighed in on "the war against cancer." And he does not like what he sees.
James Watson, co-discoverer of the double helix structure of DNA, lit into targets large and small. On government officials who oversee cancer research, he wrote in a paper published on Tuesday in the journal Open Biology, "We now have no general of influence, much less power ... leading our country's War on Cancer."
Our protest must shortcircuit the fossil fuel interests blocking Barack Obama
Change usually happens very slowly, even once all the serious people have decided there's a problem. That's because, in a country as big as the United States, public opinion moves in slow currents. Since change by definition requires going up against powerful established interests, it can take decades for those currents to erode the foundations of our special-interest fortresses.
Take, for instance, "the problem of our schools". Don't worry about whether there actually was a problem, or whether making every student devote her school years to filling out standardized tests would solve it. Just think about the timeline. In 1983, after some years of pundit throat clearing, the Carnegie Commission published "A Nation at Risk", insisting that a "rising tide of mediocrity" threatened our schools.
Totally blind mice get sight back
Totally blind mice have had their sight restored by injections of light-sensing cells into the eye, UK researchers report.
The team in Oxford said their studies closely resemble the treatments that would be needed in people with degenerative eye disease. Similar results have already been achieved with night-blind mice.
Immune system 'booster' may hit cancer
Vast numbers of cells that can attack cancer and HIV have been grown in the lab, and could potentially be used to fight disease.
The cells naturally occur in small numbers, but it is hoped injecting huge quantities back into a patient could turbo-charge the immune system. The Japanese research is published in the journal Cell Stem Cell.
Experts said the results had exciting potential, but any therapy would need to be shown to be safe.
