The CW’s Black Lightning stars a high school principal who fights criminals with the power of electricity — and karate. While it may seem implausible, the concept of a living, breathing organism carrying a powerful electrical charge without dying has some real biology behind it.

While they aren’t trained in karate, several species of fish share Black Lightning’s ability to conduct electricity and electrocute their enemies. Electric catfish, eels, and rays are just a few species who possess this power. Some fish can produce charges of up to 800 volts. That’s more voltage than the third rail of New York City’s subway system.

An electric crime-fighting principal doesn’t sound so impossible, now does it? To find out more about the science behind Black Lighting, check out this episode of Science and Chill.

Don’t miss the series premiere of Black Lightning January 16th at 9/8c on The CW.

It’s only Tuesday, but the latest batch of Fortnite: Battle Royale challenges have already leaked. We actually covered the initial news (and the mystery behind it) last week, but with Season 6 challenges quickly approaching here’s a quick guide on what you can do to prepare for the update (presumably version 5.3).

Pokémon GO has been teasing the release of Gen 4 Pokémon for a while, but now it looks like it might finally be happening. The latest news comes from popular dataminer @Chrales and includes the disclaimer that we shouldn’t get “hyped too much,” but for any Pokémon GO fans that’s probably not going to be possible.

After weeks of doing battle with Registeel in Pokémon GO, trainers will have a new Legendary Pokémon to contend with in the game’s Raid Battles. The Steel-type Pokémon tagged in one of the other Legendary titans of Hoenn, Regirock.

Niantic posted the update about the switch of Raid Battle Pokémon on the official Pokémon GO Twitter account Thursday. Players will not have to deal with the Rock Peak Legendary originally seen in the Pokémon Ruby and Pokémon Sapphire games on the Game Boy Advance. Although Regirock is tougher than Registeel, it’s a Rock-type meaning there are plenty of counters to take it down.

Fortnite: Battle Royale revealed one of its most exciting Battle Pass challenges we’ve seen in a while for Season 5 Week 6: Timed Trials. On Thursday, we rounded up more than enough trial locations to help you complete the challenge, but it turns out we still missed one of them.

If you’re struggling to complete Fortnite’s Week 6 challenge you may want to head down to Paradise Palms, the small desert city that was added to the map for Season 5. From there, head east and look for a waterfall. There, you should find one of those glowing blue stopwatch icons that will activate the timed trials challenge, according to both GameSpot and Forbes.

Fortnite: Battle Royale players might notice that their traps are not as effective as they used to be. In fact, they may be ineffective at times. Epic Games is now aware of the issue and will fix the problem, the company says.

A thread this week on the Fortnite: Battle Royale subreddit offered an example of the problem with traps in the game. Essentially, a player traps their opponent in a structure and then places a Spike Trap on the wall. But crucially, the spikes activate fail to kill the trapped player, who then destroys the Spike Trap to get out.
