After two years of testing, these are the electric toothbrushes that impressed WIRED staffers the most. The best electric toothbrush reduces plaque and gingivitis better than a manual one, encourages you to brush long enough, and prevents overzealous scrubbing (it's a thing--just ask my dentist). I didn't always to brush my teeth, but over the years, I've come to appreciate the oral-health ritual: two minutes of foamy, mindless maintenance twice a day (or more) that keeps the dental hygienist off my back. Investing in preventative dental care can save you thousands of dollars (and a lot of discomfort) in the long run. If you have a permanent retainer from orthodontics, an electric device can deal with the associated plaque buildup far more effectively than a manual toothbrush. And a electric toothbrush doesn't have to cost a fortune. We've tested dozens, including budget-friendly basic options and high-tech models packed with pressure sensors and multiple cleaning modes.

The car world is filled with designers still obsessed with shoehorning sex into their rides. Slate went a different route, and it's why people are smitten with the charming electric pickup. Tisha Johnson is a rare anomaly in the car world: a design leader for an automaker who is not a man. In a resolutely testosterone-fueled industry where, traditionally, women have seemingly been given positions of authority in design labs as long as they focus on interiors, colors, or material selections, very few have been afforded free rein on the most important visual element of the car, the exterior, let alone promoted to run the entire aesthetic show. As head of design at Slate, this gender-specific fact might be why the world has fallen in love with the Jeff Bezos-backed truck . Casual observers might put the Slate EV's popularity down to its low price. Starting at $24,950, the Slate arriving later this year won't just be the cheapest EV on the US market; it will also be the cheapest pickup truck of any power flavor.

Startups and Big Ag are using Crispr gene editing to create crops that taste better and grow on a hotter planet. But will they find a market? If you wanted to create better blackberries, you could try to breed a variety without the seeds that get stuck in your teeth. Or one without the thorns that make the berries hard to pick. Or you could aim for more environmentally efficient plants that produce more berries per acre with less water and fewer chemicals.

Billed as the "world's first museum of AI arts," Dataland uses wearables and troves of material from the Amazon to merge nature, biometrics, and art. "I think we are literally in a renaissance," says the artist Refik Anadol, in a characteristically optimistic comment, when asked how he sees this moment in art history, with artificial intelligence ascendant yet controversial as a medium. "We just don't have a name for it yet." Anadol, known for technological installations that probe the relationship between humans and machines, has reason to be happy. On June 20, Dataland, the cutting-edge downtown Los Angeles gallery he cofounded with studio partner Efsun Erkılıç, opened its doors to an eager public.
