Preparing the Next Generation of STEM Innovators
Wed, 08 Sep 2010 16:50:00 -0500
The National Science Board is releasing a new report, "Preparing the Next Generation of STEM Innovators: Identifying and Developing our Nation's Human Capital," during a press conference at the National Press Club on September 15, 2010 at 9:45 a.m.
The development of our nation's human capital through our education system is an essential building block for future innovation. Currently, the abilities of far too many of America's young men and women ...

Capacity for Exercise Can Be Inherited, UC-Riverside Biologists Find
Thu, 09 Sep 2010 13:16:00 -0500
Biologists at the University of
California, Riverside, have found that voluntary activity, such as daily exercise, is a highly heritable trait that can be passed down genetically to successive generations. Working on mice in the lab, they found that activity level can be enhanced with selective breeding. Their experiments showed that mice that were bred to be high runners produced high-running offspring, indicating that the offspring had inherited the trait for activity.

Economic Theory Suggests Symbiosis is Driven by Simple Self-interest, Not Rewards or Punishment
Thu, 09 Sep 2010 13:17:00 -0500
Applying employment
contract theory to symbiosis, a new paper suggests mutually beneficial relationships are maintained by simple self-interest, with partners benefiting from healthy hosts much as employees benefit from robust employers. The new work discounts the theory that host species have evolved to promote symbiosis by promising rewards or threatening punishment.

Caltech Mineral Physicists Find New Scenery at Earth's Core-mantle Boundary
Thu, 09 Sep 2010 13:17:00 -0500
Using a diamond-anvil
cell to recreate the high pressures deep within the Earth, researchers at the California Institute of Technology have found unusual properties in an iron-rich magnesium and iron-oxide mineral that may explain the existence of several ultra-low velocity zones at the core-mantle boundary. A paper about their findings was published in a recent issue of Geophysical Research Letters.

Miniature Auto Differential Helps Tiny Aerial Robots Stay Aloft
Thu, 09 Sep 2010 13:18:00 -0500
Engineers at Harvard
University have created a millionth-scale automobile differential to govern the flight of minuscule aerial robots that could someday be used to probe environmental hazards, forest fires, and other places too perilous for people. Their new approach is the first to passively balance the aerodynamic forces encountered by these miniature flying devices, letting their wings flap asymmetrically in response to gusts of wind, wing damage and other real-world impediments.

Study Adds Clue to How Last Ice Age Ended
Wed, 08 Sep 2010 14:08:00 -0500
As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned.
But oddly, despite bitter cold winters in the north, Antarctica was heating up.
For the two decades since ice core records revealed simultaneous warming and cooling at opposite ends of the planet during this time period, scientists have looked for an explanation.
Results of a new study published this week in the ...
