The $30 million award goes unclaimed, but the race to the moon is still on. Find out who wants to go and why this is not your parents’ – or grandparents’ – space race. With or without a cash incentive, private companies are still eyeing our cratered companion, hoping to set hardware down on its dusty surface. Meanwhile, while the U.S....

Hundreds of thousands of scientists took to the streets during the March for Science. The divisive political climate has spurred some scientists to deeper political engagement – publicly challenging lawmakers and even running for office themselves. But the scientist-slash-activist model itself is contested, even by some of their colleagues. Find out how science and politics have been historically intertwined, what motivates scientists to get involved, and the possible benefits and harm of...

ENCORE Know your brain? Think again. Driven by a hidden agenda, powered by an indecipherable web of neurons, and influenced by other brains, your grey matter is a black box. To "know thyself" may be a challenge, and free will nonexistent, but maybe more technology can shed light on the goings on in your noggin, and the rest of your body. Find out how tiny implanted sensors called “brain dust” may reveal what really going on. Plus, the day when your brain is uploaded into a computer as...

Stephen Hawking felt gravity’s pull. His quest to understand this feeble force spanned his career, and he was the first to realize that black holes actually disappear – slowly losing the mass of everything they swallow in a dull, evaporative glow called Hawking radiation. But one of gravity’s deepest puzzles defied even his brilliant mind. How can we connect theories of gravity on the large scale to what happens on the very small? The Theory of Everything remains one of the great...

Insect populations are declining. But before you say “good riddance,” consider that insects are the cornerstone of many ecosystems. They are dinner for numerous animal species and are essential pollinators. Mammals are loved, but they are not indispensable. Insects are. Meanwhile, marvel at the extraordinary capabilities of some insects. The zany aerial maneuvers of the fly are studied by pilots. And, contrary to the bad press, cockroaches are very clean creatures. Also, take a listen as...

ENCORE We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators. So why did squids and octopuses lose their shells? Find out what these cephalopods gained by giving up the shell game. Plus why Chesapeake Bay oyster shells are shells of their former selves. What explains the absence of the dinner-plate sized oysters of 500,000 years ago, and how conservation paleobiology is probing deep time for...

It takes a lot of energy and technology to leave terra firma. But why rocket into space when there’s so much to be done on Earth? From the practical usefulness of satellites to the thrill of exploring other worlds, let us count the ways. The launch of a NOAA weather satellite to join its twin provides unparalleled observation of storms, wildfires, and even lightning. Find out what it’s like to watch hurricanes form from space.

Move over Roomba. Café robots are the latest in adorable automation. And they may be more than a fad. As robots and artificial intelligence enter the workforce, they could serve up more than machine-made macchiato. Digital workers are in training to do a wide variety jobs. Will humans be handed the mother of all pink slips? We sip lattes in a robot café and contemplate the future of work. Some say the workplace will have more machines than people, while others maintain that A.I. will...

ENCORE Einstein thought that quantum mechanics might be the end of physics, and most scientists felt sure it would never be useful. Today, everything from cell phones to LED lighting is completely dependent on the weird behavior described by quantum mechanics. But the story continues. Quantum computers may be millions of times faster than your laptop, and applying them to big data could be transformational for biology and health. Quantum entanglement – “spooky” action at a distance – may...

It was a shocker of a story, splashed across the New York Times front page: The existence of a five-year long, hidden Pentagon investigation of UFOs. With one-third of the American public convinced that aliens are visiting Earth, could this study finally provide the proof? We consider how this story came to light and what the $22 million program has produced. Does the existence of a secret study mean there’s now decent proof of extraterrestrial craft in our skies? We take a look at the...

ENCORE For a half-century, space has been the playground of large, government agencies. While everyone could dream of becoming an astronaut, few could actually do so. Things have changed.

And while you’re waiting for a ticket to ride, why not build your own satellite to keep tabs on the kids or just check out the back forty? A CubeSat could be...

ENCORE The record of the rocks is not just the history of Earth; it’s your history too. Geologists can learn about events going back billions of years that influenced – and even made possible – our present-day existence and shaped our society. If the last Ice Age had been a bit warmer, the rivers and lakes of the Midwest would have been much farther north and the U.S. might still be a small country of 13 states. If some Mediterranean islands hadn’t twisted a bit, no roads would have led...
