The Justice Department has announced charges against four people, including two Russian security officials, over cybercrimes linked to a massive hack of millions of Yahoo user accounts.

Mitch Seavey has been the first to cross the finish line under the famed burled arch before — he previously won the famed Alaska Iditarod Trail Sled Dog Race in 2013 and 2004.

This year he became the fastest and the oldest musher to win the race.

He also beat his son, defending champion Dallas Seavey, who had wins in 2012 and 2014.

In fact, Mitch Seavey shaved several hours off the record that his son set last year.

Seavey won the race, arriving in Nome in 8 days, 3 hours, 40 minutes and 13 seconds, race stats show.

Scientists have caught sight of a star extremely close to what they think is a black hole, whizzing around it at an extraordinary speed — at least twice an hour. As NASA put it, "This may be the tightest orbital dance ever witnessed for a likely black hole and a companion star."

The pair is in our galaxy, in an area dense with stars some 14,800 light-years from Earth.

The makers of the We-Vibe, a line of vibrators that can be paired with an app for remote-controlled use, have reached a $3.75 million class action settlement with users following allegations that the company was collecting data on when and how the sex toy was used.

Standard Innovations, the Canadian manufacturer of the We-Vibe, does not admit any wrongdoing in the settlement finalized Monday.

Last month, Nike released a new digital ad targeted to women in the Arab world. It features different women athletes in the Middle East, including figure skater Zahra Lari from the United Arab Emirates; fencer Inès Boubakri from Tunisia and boxer Arifa Bseiso from Jordan.

A few months ago, at her office in Houston, Kate Rubins was feeling weird.

She was dizzy, she says — "staggering around like a 2-year-old who had just learned to walk." She was constantly looking at her desk to make sure the objects on top weren't floating away.

Rubins wasn't going nuts. She was just readjusting to Earth after living without gravity for four months, hundreds of miles above the planet's surface.

An orangutan named Rocky is helping scientists figure out when early humans might have uttered the first word.

Rocky, who is 12 and lives at the Indianapolis Zoo, has shown that he can control his vocal cords much the way people do. He can learn new vocal sounds and even match the pitch of sounds made by a person.

Reading isn't usually a competitive sport. But it's become one for Braille readers because of a lack of excitement about Braille.

Right now, the Los Angeles-based Braille Institute is putting on regional competitions like this one in a classroom at the Tennessee School for the Blind.

A braille reading competition actually looks more like a typing contest.

As competition begins, students flip through their packets. Their spread fingers sweep over the square pages.

That black three-ring binder is one way to do it. Later this week, a more high-tech version by the digital design agency Huge is launching. Developer Natalia Margolis says she got the idea after talking with an advocate for people here illegally.

Countersurveillance fashion designs are being spotlighted at this year's South by Southwest conference in Austin, Texas, by a group of young women of color who started a company called Hyphen-Labs.

They are scientists, architects and engineers turned artists "creating critical work for critical times," says Ashley Baccus-Clark, a speculative neuroscientist and member of the collective, which includes designers from around the globe.
