Heading to the US to escape Australian heat? You're going from one extreme to the other. With snow falling in Florida and temperatures along the East Coast dipping well below zero, the need for a good winter jacket has never been greater. The warmth from your body wants to get out into the cold atmosphere—that's just simple thermodynamics—but a good jacket can keep it from escaping, even when the temperatures hit “polar vortex” or “bomb cyclone” levels of frigidity.

Ryan Knapp is a senior staff meteorologist and weather observer at the Mount Washington Observatory in White Mountains, New Hampshire. When we talked on the phone, the temperature at the observatory—which is at the mountain's summit— was hovering between -20 and -30 degrees. Most of us experience painfully frigid temperatures like that rarely, if ever, but it's not out of the ordinary for Knapp and the Mount Washington crew.
Every January, fat's in the crosshairs of health columnists, fitness magazines, and desperate Americans. This year, PopSci looks at the macronutrient beyond its most negative associations. What's fat good for? How do we get it to go where we want it to? Where does it wander when it's lost? This, my friends, is Fat Month.
Do you ever feel like your drinking water is just too clean? Last week, The New York Times reported on a trendy new beverage known as raw water. Yes: people are spending loads on unfiltered, untreated, and totally unsterilized spring water.
Extreme diets are just the nutritional version of 30-day fitness challenges. Nearly everyone tries them at some point, but they don't generally turn your life around. We seek out both for the same reason: because it's often not good enough for us to make a change. It also has to feel like we've made a change.
Since the late 1700s, Norwegian rats have haunted New York City's alleys, parks, and basements. They came on ships from France and England, and then they never left.
Google Street View images are filled with cars. That is a simple and pedestrian truth, and one which artificial intelligence researchers have taken advantage of to do something surprising. By analyzing car type, they were able to make predictions about the demographic information of the people in the cities they studied.
If something claims to be a miracle cure—for cancer, for overeating, for run-of-the-mill acne—you should start by assuming it isn't. Life is hard and long and there are no easy shortcuts, especially when it comes to your health. That includes the internet darling that is apple cider vinegar.
Ask Jodi Sherman to identify a culprit in global climate change, and you'll get an unexpected answer. The anesthesiologist from Yale University doesn't name the usual suspects—carbon dioxide, like the kind that spews out of our cars, or methane, the gas packed into every cow burp. Instead, she points a finger at anesthesia, the tool most essential to her trade. “And it's just being released into the atmosphere with no control,” she says.
One would assume that many of the strongest members of our species are elite athletes. And if particularly strong arms are what you're after, collegiate rowers—who routinely exert many times their body weight in power to propel a boat forward as fast as humanly possible—are about as good as it gets. But according to a new study, even elite female rowers have nothing on the arms of prehistoric women.
