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.

When the Mars Curiosity made its dramatic and first-of-its-kind landing on Mars in August of 2012, the hope was that the $2.5-billion rover could confirm what scientists had suspected: that there was life on Mars.
Today, in a paper released in the journal Science, researchers explain that if the Red Planet is harboring life, the instruments on the rover have been unable to sniff it out.

Orbital Sciences' Cygnus spacecraft has successfully launched from NASA's Wallops Flight Facility in Virginia on its way to becoming the second private vehicle to resupply the International Space Station.
