In the U.S., the rising trend of dog ownership goes hand in hand with a surge in people seeking allergy-friendly canine companions.

About 1 in 4 people with anorexia nervosa or bulimia nervosa will attempt to kill themselves, an ...read more

While a plant-based diet avoids animal products, a carnivore diet allows its followers to consume only meat and other animal products — a limit, some say, that comes with a host of health benefits. Philip Ovadia, a Florida-based cardiothoracic surgeon is one of the diet’s avid proponents. Ovadia, who first went low-carb before transitioning to fully carnivore five years ago, credits the lifestyle change for helping him lose weight and increase his energy and mental clarity. “During the eig ...read more

You step outside into snow-dusted streets, filling your lungs with the crisp air as you feel that satisfying crunch beneath your feet. It’s only later, when you look at your bare hands back inside, that you see (and feel) it: Red, raw, and rough skin, as itchy as it is uncomfortable.It’s almost a given that your skin will get drier and flakier in the winter months — perhaps even after you’ve already slathered it with moisturizer. But why, specifically, do our hands, feet, and lips become ...read more

Around the turn of the century, microbiologists at Danisco USA Inc. had a problem: The bacteria they used to make yogurt and cheese were getting infected with viruses. Investigating more deeply, the scientists found that some bacteria possessed a defense system to fight off such viral invaders. These virus-resistant bacteria carried weird, repetitive collections of DNA letters in their chromosomes — bits of DNA from their encounters with past viruses that the microbes had “saved” in their ...read more

What defines humanity? Is it the fact that we can walk upright on two legs? That we have brains big enough to use tools? That we can organize our societies well enough to find wonderful ways of exploiting the resources of the planet — and each other?While the answer may seem clear enough to anyone who doesn’t think too closely about it, anthropologists — the scientists who actually study humans — aren’t necessarily so certain.“We’re using this term and it’s not quite colloquial a ...read more

If you can sense changes in the weather based on aches and pains in your body, you aren’t alone. Many people, especially older individuals with arthritis, claim that they can feel the weather based on the pain in their joints. While research hasn’t nailed down these weather-related pain claims, anecdotal evidence persists. How the Weather Impacts Your JointsIt’s probably why so many people want to retire where it’s warm, says Aly Cohen, a rheumatologist in Princeton, New Jersey. Cold we ...read more

What makes us human? Many answers would suffice, but in particular, our names offer an overlooked perspective on our humanity. Perhaps this is because names fall on somewhat of a nebulous side of our identity. Names aren’t etched onto our DNA, and technically, they can be abandoned or customized at the whim of their owners. But for most, a name clings until the end of life and exists beyond death. To understand how we distinguish one another with names, you would need to sift through unfathoma ...read more

Time outside with your dog in the spring, summer and fall can be lovely.
