Fighting Fire with Fire

Fighting Fire with Fire

Robert Kremens fights fire with fire. No, really – that’s his job. Kremens sets fires in a host of locations across the US. In April he drove 18 hours from his home in Rochester, New York, to Tall Timbers, a research station in Tallahassee, Florida, to set three or four [Read More]

The quantum world is mind-bogglingly weird

The quantum world is mind-bogglingly weird

If you’re interested in the smallest things known to scientists, there’s something you should know. They are extraordinarily ill-behaved. But that’s to be expected. Their home is the quantum world. These subatomic bits of matter don’t follow the same rules as [Read More]

Predicting the whirlwind

  In more than 20 years as a meteorologist, Joshua Wurman had seen – and chased – more than 150 tornadoes. But the one that hit his pickup truck caught him by surprise. On a warm spring evening in 2012, Wurman was driving down a two-lane highway in the small plains [Read More]

Auto-focus eyeglasses rely on liquid lenses

Auto-focus eyeglasses rely on liquid lenses

With round lenses set in super-thick frames, these new eyeglasses look like they belong on a cartoon character. But what they lack in style, they make up for in smart design. Their lenses are made of glycerin — a thick, colorless liquid — encased in clear rubber. And [Read More]

The return of supersolids!

The return of supersolids!

We learn it from a young age: solids hold their shapes; liquids flow. Physical states of matter are mutually exclusive. A solid occupies a particular position in space, its molecules fixed. A fluid assumes the shape of its container, its molecules in constant motion. But a [Read More]

  In central California’s Yosemite National Park, it doesn’t take much to set the forest on fire. A discarded cigarette. A match. Or, as is often the case, a bolt of lightning. On July 31, 2011, thunder boomed as a severe storm pelted the park. The lightning struck [Read More]

Hacking the Planet

A person with a failing vital organ usually has only one treatment option: get a new one. But right now, that often means joining a long waiting list and hoping for the best. Moving up that list means someone ahead of you gets taken off it – either through their death, [Read More]
