When a rocket carrying the first module of the International Space Station blasted off from Kazakhstan in November of 1998, NASA officials said the station would serve as an orbiting home for astronauts and cosmonauts for at least 15 years.

Mike Morrison hardly looks like a revolutionary. He's wearing a dark suit and has short hair. But we're about to enter a world of conformity that hasn't changed in decades — maybe even a century. And in there, his vision seems radical.

"We are about to walk into a room full of 100 scientific posters, where researchers are trying to display their findings on a big poster board," says Morrison, a doctoral student in psychology at Michigan State University.

At the Marine Biological Laboratory in Woods Hole, Mass., there's a room filled with burbling aquariums. A lot of them have lids weighed down with big rocks.

"Octopuses are notorious for being able to, kind of, escape out of their enclosures," says Bret Grasse, whose official title at MBL is "manager of cephalopod operations" — cephalopods being squid, cuttlefish and octopuses.

Imagine spending 40 years and more than a billion dollars on a gamble.

That's what one U.S. government science agency did. It's now paying off big time, with new discoveries about black holes and exotic neutron stars coming almost every week.

The asteroid is in a horrible orbit and has a 1% chance of striking Earth in just eight years. And — thank goodness — it doesn't really exist.

It's a fictitious asteroid that's the focus of a realistic exercise devised for scientists and engineers from around the world who are attending the 2019 Planetary Defense Conference being held this week outside Washington, D.C.

A real asteroid of this size, should it ever hit the planet, could wipe out an entire city.

The brains of dead pigs have been somewhat revived by scientists hours after the animals were killed in a slaughterhouse.

The Yale University research team is careful to say that none of the brains regained the kind of organized electrical activity associated with consciousness or awareness. Still, the experiment described Wednesday in the journal Nature showed that a surprising amount of cellular function was either preserved or restored.

Salt has existed for millions of years. The Salt Institute has existed for just over a century. And now it has dissolved.

Mosquitoes searching for a meal of blood use a variety of clues to track down humans, including our body heat and the carbon dioxide in our breath. Now, research shows that a certain olfactory receptor in their antennae also serves as a detector of humans, responding to smelly chemicals in our sweat.
