The first sign that something was wrong came with stomach pains. It was April 30, and 9-year-old Kyree McBride wasn't feeling well.

His mother, Tammie Hairston, thought it might have been something that he ate. But soon, young McBride was battling a 102-degree fever.

Worried he may have contracted the coronavirus, Hairston took her son to the hospital. "It was a quick in and out of the emergency room," she said. Doctors told her to take him home and monitor him.

The old way to think about your dog's "human age" — the age in actual years times seven — is wrong. And researchers now have a new formula they think will calculate your dog's age more accurately.

Simply put, compared with humans, dogs age very quickly at first, but then their aging slows down, a lot.

Trey Ideker of the University of California, San Diego was part of a team of researchers that looked at aging on the molecular level.

What did a meal taste like nearly 4,000 years ago in ancient Babylonia? Pretty good, according to a team of international scholars who have deciphered and are re-creating what are considered to be the world's oldest-known culinary recipes.

The recipes were inscribed on ancient Babylonian tablets that researchers have known about since early in the 20th century but that were not properly translated until the end of the century.

Each summer for the last two decades, Jim Parker has readied his small whale watch boat, and made a business out of ferrying tourists out into the cool blue waters of the Gulf of Maine.

For years, it was steady work. The basin brimmed with species that whales commonly feed on, making it a natural foraging ground for the aquatic giants. Whales would cluster at certain spots in the gulf, providing a reliable display for enchanted visitors to the coastal community of Milbridge, Maine.

With an olive-green body encasing three jaws, each lined with more than 50 teeth, it looks like a cigarette-sized relative of the skin-crawling creature from the Alien films. Actually, it's far less sinister: a new species of a bloodsucking leech.

Anna Phillips, the curator of parasitic worms at the Smithsonian's National Museum of Natural History in Washington, D.C., led the team that recently discovered Macrobdella mimicus in almost their own backyard.

Louis Armstrong has served as the focus of many works of literature. Now, a few seconds of old film that appear to feature Armstrong as a teenage boy have captivated jazz journalist James Karst. If Karst's theory is correct, the clip from 1915 shows Armstrong at a turning point in his early life — years before he became famous and eventually legendary around the world.

A new generation of migrants is arriving in Mexico: young adults who were born in Mexico, raised in the United States and are now returning — some voluntarily, some by force — to the country of their birth. They've been dubbed "Generation 1.5."

With only limited support available from the Mexican government for these often well-educated returnees, several nongovernmental organizations and at least one private company are looking to help them out and take advantage of their skills.

When 29-year-old Gilberto Olivas-Bejarano first returned to his birth country of Mexico, he didn't speak the native language.

"I barely speak Spanish now," he says.

He arrived in León alone, and today, nearly two years since his deportation, Olivas-Bejarano has still not seen his parents or siblings in person.

On a sunny, late-September afternoon in the garden of a guesthouse in Kabul, just beyond the armed guard at the iron gate, a couple of girls are tuning up for guitar practice. All headscarves and concentration, they stretch tentative fingers along the strings. Their teacher, a 56-year-old musician from Los Angeles named Lanny Cordola, sports own head covering, a green doo-rag holding in check a graying ponytail that drifts down the middle of his back.

It is April Fools Day 2011 and Jimmy Chin, the renowned adventure photographer and filmmaker, is shooting a couple of professional snowboarders in the Teton Range in Wyoming. This is one of the first really warm days of the spring season and so there is a lot of action in the snowpack. It is the kind of day where the risk of avalanche is high enough that everyone has their antennae up. But all three men are expert mountaineers who know how to read the conditions.

Sometimes you can tell a lot about a country just by walking its beaches. That's what I did on my last day in Freetown, the capital of Sierra Leone, where I was on assignment covering the Ebola epidemic.

Standing at water's edge, facing the sea. The smooth blue rollers come splashing in, steady, hypnotic — like oceans anywhere in the world.

On a recent day, just west of Kabul — where the city's sooty sky gives way to fresher air — Abdul Sadiq coaches four young members of the Afghan National Cycling Federation. They're working on their riding technique while dodging the free-form traffic.

"The road is very narrow. Make sure you don't get into an accident, as you can see the cars are coming," the former competitive cyclist tells them, amid zooming vehicles and honking horns.
