During an experiment, marketing professor Remi Trudel noticed a pattern in what his volunteers were recycling versus throwing in the garbage. He then went through his colleagues' trash and recycling bins at Boston University for more data.
He found the same pattern, says NPR's Shankar Vedantam: "Whole sheets of paper typically went in the recycling, but paper fragments went in the trash."
Same type of paper, different shapes, different bins.
One thing you can say about the diminutive speckled sea louse: it's always on time.
Scientists studying the tiny crustacean, a marine cousin of the wood-louse, found that it runs not one, but two internal clocks. Not only does the creature have a circadian rhythm, or so called "body clock" like most land-dwelling animals, including humans, but it also has a circatidal clock that follows the 12.4-hour cycle of the tide.
What would it take to persuade you to allow government researchers to squirt millions of live flu viruses up your nose?
A recently concluded project at the National Institutes of Health found, among other things, that $3,400 each was enough to attract plenty of volunteers.
"I am happy I could contribute in some way," says Kelli Beyer, 24, one of 46 healthy people who volunteered for the project. To get the money, the research subjects had to commit to several days of testing, then nine days in a hospital isolation ward once the virus was administered in a nasal spray.
Have you enjoyed a salad of greens and fresh veggies for lunch recently? Or a dinner of pasta (made without eggs), mixed with olives and tomatoes? If so, even if you ate cheese or meat or fish on other days, you're a part-time vegan.
A newly discovered fossil of a fish in China changes what scientists know about the origins of jaws. It turns out, human jaws are remarkably similar to the jaw of this 419-million-year-old fish. That suggests jaws evolved much earlier than previously thought.
As faces go, Entelognathus primordialisisn't much to look at, even for a fish.
But consider that the 419 million-year-old, armor-plated fish is the earliest known creature to have what humans might recognize as a face, according to research published Wednesday in Nature. That's mostly due to its bony, modern jaw.

This month, for the first time in history, a probe built by humans left the confines of the solar system for the depths of interstellar space. NASA launched Voyager 1 in September 1977, when Jimmy Carter was president and I had just finished high school.
The era of interstellar travel, up to now the exclusive province of sci-fi, has officially begun.

From vacant lots to vertical "pinkhouses," urban farmers are scouring cities for spaces to grow food. But their options vary widely from place to place.
While farmers in post-industrial cities like Detroit and Cleveland are claiming unused land for cultivation, in New York and Chicago, land comes at a high premium. That's why farmers there are increasingly eyeing spaces that they might not have to wrestle from developers: rooftops that are already green.
