1 IN THE SKIES OVER AL AIN, IN THE United Arab Emirates, pilot Mark Newman waits for the signal. When it comes, he flicks a few silver switches on a panel by his leg, twists two black dials, then punches a red button labeled FIRE.
A slender canister mounted on the wing of his small propeller plane pops open, releasing a plume of fine white dust. That dust-actually ordinary table salt coated in a nanoscale layer of titanium oxide-will be carried aloft on updrafts of warm air, bearing it into the heart of the fluffy convective clouds that form in this part of the UAE, where the many-shaded sands of Abu Dhabi meet the mountains on the border with Oman. It will, in theory at least, attract water molecules, forming small droplets that will collide and coalesce with other droplets until they grow big enough for gravity to pull them out of the sky as rain.
This is cloud seeding. It's one of hundreds of missions that Newman and his fellow pilots will fly this year as part of the UAE's ambitious, decadelong attempt to increase rainfall in its desert lands.
Sitting next to him in the copilot's seat, I can see red earth stretching to the horizon. The only water in sight is the swimming pool of a luxury hotel, perched on the side of a mountain below a sheikh's palace, shimmering like a jewel.
More than 50 countries have dabbled in cloud seeding since the 1940s-to slake droughts, refill hydroelectric reservoirs, keep ski slopes snowy, or even use as a weapon of war. In recent years there's been a new surge of interest, partly due to scientific breakthroughs, but also because arid countries are facing down the early impacts of climate change. Like other technologies designed to treat the symptoms of a warming planet (say, pumping sulfur dioxide into the atmosphere to reflect sunlight into space), seeding was once controversial but now looks attractive, perhaps even imperative.

Spin Cycle - To study tornadoes, it helps to wear a skirt (and rocket launchers).
To study tornadoes, it helps to wear a skirt (and rocket launchers). When the Dominator is about to intercept a tornado, Timmer uses a two-prong system to anchor the vehicle. Air compressors lower the car so its thick rubber skirt nearly touches the ground, and spikes wedge 6 inches into the earth to firmly prevent the vehicle from liftoff. Timmer and ONeal have seen roughly 65 tornadoes in the past six months. It was a historic amount, ONeal says. A lot of meteorological setups are busts, but every day we drove out this year, we felt like we would see a tornado.
Fantastic Plastic - a plastic bag might be the most overengineered object in history.
Stretchy seaweed. Reverse vending machines. QR-coded take-out boxes. To cure our addiction to disposable crap, we'll all need to get a little loony.
Piece of Mind - This diagram maps 1 cubic millimeter of the brain-but its unprecedented clarity deepens the mysteries of cognition.
This diagram maps 1 cubic millimeter of the brain-but its unprecedented clarity deepens the mysteries of cognition. Although this image wouldn't look out of place on a gallery wall alongside other splashy works of abstract art, it represents something very real: a 1-cubic-millimeter chunk of a woman's brain, removed during a procedure to treat her for epilepsy. Researchers at Harvard University stained the sample with heavy metals, embedded it in resin, cut it into slices approximately 34 nanometers thick
I Am Laura Kipnis-Bot, and I Will Make Reading Sexy and Tragic Again
WHEN A FLATTERING EMAIL ARRIVED inviting me to participate in an AI venture called Rebind that I'd later come to think will radically transform the entire way booklovers read books, I felt pretty sure it was a scam.

COOLER HEADS
The deadliest environmental threat to city dwellers worldwide isn't earthquakes, tornadoes, flooding, or fire. It's heat.
