A lot of power means a lot of heat. NASA's future missions to explore the Moon and Mars will require enormous amounts of electrical power and hardware to support astronauts and drive new technologies. This increase in power, however, also increases the amount of heat generated-and then that heat needs to be removed so all the spacecraft systems can function.

It's the weekend, and freshly caught fish sizzles on the grill. The view: an unforgettable beach and the cobalt blues of the Pacific Ocean in the backdrop.
This is not paradise. It's a typical Sunday for many people in Palau, an archipelago nation in Micronesia.

When Hurricane Irma hit southern Florida in September of 2017, the storm buffeted coastal mangrove forests with winds over 116 mph - strong enough to rip off leaves, break branches, and snap tree trunks in half. Of the mangrove forest damaged by Hurricane Irma, about 83% recovered after the first year. But the rest didn't, leaving scientists wondering why some trees didn't bounce back.

Virtually all oxygen on Earth was and is produced by photosynthesis, which was invented by tiny organisms, the cyanobacteria, when our planet was still a rather uninhabitable place. Cyanobacteria evolved more than 2.4 billion years ago, but Earth only slowly transformed to the oxygen-rich planet we know today.

A shortage of semiconductors has sent shockwaves through the global economy, squeezing supplies of everything from cars to headphones.
The dearth of chips has exposed the modern world's reliance on these miniscule components, the basic building blocks of computers which allow electronic devices to process data. Why is the shortage happening, and what can be done about it?
