We're All in the Clean-Plate Club
Study: Tyrannosaurs Ran in Gangs
Wyoming Cave To Be Excavated
Audit: NASA Can't Afford Big Rockets
Bats Navigate Using Polarized Light
Seems that most of us take to heart the common admonition to clean our plates, at least when we fill them ourselves. Adults eat nearly 92% of the food they put on their plates, according to new research.
Talk about a triple threat! If you thought tyrannosaurs weren't scary enough, try three of them at once. Turns out these fearsome beasts weren't solitary hunters -- they ran in gangs.
Scientists are about to revisit one of North America's most remarkable troves of ancient fossils: the bones of tens of thousands of animals piled 30 feet deep at the bottom of a sinkhole-type cave.
NASA doesn't have enough money to get its new, $12 billion rocket system off the ground by the end of 2017 as planned, federal auditors say, but the agency is making progress on rocket design.
For longer-term navigation bats must rely on a suite of cues including what they can see, the Earth's magnetic field and, according to a new study, patterns of polarized light in the sky at dusk.
