One day in 1992, near the northern pole of a planet hurtling around the Milky Way at roughly 500,000 miles per hour, Kelly Drew was busy examining some salmon brains in a lab. Her concentration was broken when Brian Barnes, a zoophysiology professor from down the hall at the University of Alaska Fairbanks, popped by her bench for a visit. With a mischievous grin, he asked Drew-a neuropharmacologist early in her career to hold out her hands and prepare for a surprise. A moment later, she felt a hard, furry lump deposited in her palms. It was some sort of brown rodent with dagger-like claws, curled up into a tight ball and so cold to the touch that Drew assumed it was dead. To her astonishment, Barnes gleefully explained that it was actually in perfect health.
The creature, an Arctic ground squirrel, was just hibernating, as it does for up to eight months of the year. During that span, the animal's internal temperature falls to below 27 degrees Fahrenheit, literally as cold as ice. Its brain waves become so faint that they're nearly impossible to detect, and its heart beats as little as once per minute. Yet the squirrel remains very much alive. And when spring comes, it can elevate its temperature back to 98.6 degrees in a couple of hours.
Drew cradled the unresponsive critter in her hands, unable to detect even the faintest signs of life. What's going on inside this animal's brain that allows it to survive like this? she wondered. And with that question, she began to burrow into a mystery that would carry her decades into the future.

Cooler Heads - The deadliest environmental threat to city dwellers worldwide isn't earthquakes, tornadoes, flooding, or fire. It's heat.
The deadliest environmental threat to city dwellers worldwide isn't earthquakes, tornadoes, flooding, or fire. It's heat. In Phoenix, Arizona, where almost 400 people died from heat exposure last year-and where falling on the pavement can leave a third-degree burn-the question isn't whether this summer's temperatures will kill people, it's how many.
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.
