There is a certain kind of look I get when I tell people how much I love video games.

It lies somewhere between "You're not serious" and "Oh my God, you are serious." And by "people" giving me these looks, I mean adults of a certain age and outlook. Of course, given that I'm a 54-year-old tenured professor, these "people" are pretty much everyone I know (including my now adult children).

So today, I want to speak to all of you "look-givers" and attempt to explain why you, too, should become a gamer.

Basically, it comes down to robot dinosaurs.

What if you could go back in time and follow your food from the farm to your plate? What if you could see each step of your meal's journey — every ingredient that went into its creation, and every footprint it left behind?

If you're tired of popping pain medicine for your lower back pain, yoga may be a good alternative.

New research finds that a yoga class designed specifically for back pain can be as safe and effective as physical therapy in easing pain.

The yoga protocol was developed by researchers at Boston Medical Center with input from yoga teachers, doctors and physical therapists.

Broken teeth are all too often a punchline in conversations about poor people in rural places. But for Heather Wallace, dental problems are anything but funny.

"Basically it's just like a nerve pain. Your whole body locks up; you have to stop for a second to try to breathe," she said. "And sometimes if it hurts bad enough, you might cry."

President Trump has often accused the news media of not covering terrorist attacks adequately. In a speech in February he said, "Radical Islamic terrorists are determined to strike our homeland as they did on 9/11, as they did from Boston to Orlando to San Bernardino [...] It's gotten to a point where it's not even being reported."

Ethiopia gave the world Coffea arabica, the species that produces most of the coffee we drink these days. Today, the country is the largest African producer of Arabica coffee. The crop is the backbone of the country's economy – some 15 million Ethiopians depend on it for a living.

There's a good chance something you've bought online has been in the hands of a "picker" first. These are the workers in warehouses who pick, pack and ship all those things we're ordering.

As we just heard, Alaska Republican Lisa Murkowski is among those lawmakers with reservations about the direction of the Senate's health care bill. Alaska is a deeply red state, but many of its rural residents depend on Medicaid for health care.

Diarrhea is not only a topic that makes people a bit squeamish, it turns out to be a difficult disease to put into numbers.

But two trends are clear, says an author of a new report: The number of deaths from diarrheal diseases is dropping dramatically in low-income countries – and ticking upward in wealthy nations.

In 2010, Sonia Vallabh watched her mom, Kamni Vallabh, die in a really horrible way.

First, her mom's memory started to go, then she lost the ability to reason. Sonia says it was like watching someone get unplugged from the world. By the end, it was as if she was stuck between being awake and asleep. She was confused and uncomfortable all the time.

"Even when awake, was she fully or was she really? And when asleep, was she really asleep?" says Sonia.

Do you know where your workplace's automated external defibrillator is located? About half of all U.S. employees don't, according to the results of an American Heart Association survey.

Emma Carpita is just 2 weeks old. Her parents, Federico and Loredana, have brought the crying infant to her first medical checkup.

Dr. Patrizia Franco, Emma's pediatrician, hands them a list of vaccine centers in the area. "Do you have any questions or concerns?" she asks.

"No," says Federico. "We think all parents should be obligated to vaccinate their children."
