| Aerobic fitness boosts learning, memory in 9-10-year-old children Posted: 11 Sep 2013 03:47 PM PDT Physical fitness can boost learning and memory in children, particularly when initial learning on a task is more challenging.  |
| Who's got guts? Young infants expect animals to have insides Posted: 11 Sep 2013 01:10 PM PDT A team of researchers has shown that 8-month-old infants expect objects they identify as animals to have insides.  |
| 'Love hormone' may play wider role in social interaction than previously thought Posted: 11 Sep 2013 10:19 AM PDT Oxytocin -- often referred to as "the love hormone" because of its importance in the formation and maintenance of strong mother-child and sexual attachments -- is involved in a broader range of social interactions than previously understood.  |
| American families taking 'divergent paths' Posted: 11 Sep 2013 06:27 AM PDT After a period of relative calm during the 1990s, rapid changes in American families began anew during the 2000s, a new analysis suggests.  |
| Patient embraces personalized approach to lung cancer diagnosis Posted: 10 Sep 2013 01:53 PM PDT As a woman in her mid-forties who didn't smoke, Elizabeth Lacasia never expected to be diagnosed with lung cancer. But in 2006, after she developed a persistent and serious cough, a chest X-ray and CT scan revealed several tumors in her lower left lung. With the assistance of personalized medicine, her cancer is now in remission.  |
| Warnings may be ineffective at teaching young people about risks Posted: 09 Sep 2013 02:20 PM PDT Young people have greater difficulty in learning from bad news to interpret their risk of future events, which might explain why they often do not respond to warnings.  |
| African-Americans at higher risk for health problems from insufficient sleep Posted: 09 Sep 2013 02:20 PM PDT Blacks are more likely than whites to sleep less than seven hours a night, and the black-white sleep disparity is greatest in professional occupations.  |
| Five percent of US children, teens classified as 'severely obese' Posted: 09 Sep 2013 01:27 PM PDT About five percent of American children and teens are severely obese -- putting them at high risk for premature heart disease and type 2 diabetes. Severe obesity is a newly defined class of risk, and effective treatment options for these children are limited.  |

| Plants in space: A novel method for fixing plant tissue samples maximizes time, resources, and data Posted: 11 Sep 2013 03:48 PM PDT Researchers are working to understand plant growth and development in spaceflight. They have developed a single fixation protocol for use in space that allows plant material to be used for multiple experimental applications. The new protocol boasts low costs and wide application to any situation where recovery of biological resources is limited.  |
| Calculating the true cost of a ton of mountaintop coal Posted: 11 Sep 2013 03:48 PM PDT To meet current US coal demand through surface mining, an area of the Central Appalachians the size of Washington, D.C., would need to be mined every 81 days. A one-year supply of coal would require converting about 310 square miles of the region's mountains into surface mines, according to a new analysis.  |
| Astronomers explain why disk galaxies eventually look alike Posted: 11 Sep 2013 10:17 AM PDT Astronomers have discovered the fundamental process responsible for the smooth, steady fade of older disk galaxies. They say the key is the clumps of interstellar gases and new stars within young galaxy disks.  |
| Posted: 11 Sep 2013 10:17 AM PDT Chemists have found a way to apply a "foundational reaction" of organic chemistry to a stubborn class of chemicals, in a transformation that has been thought impossible for a century.  |
| Nano-optics: Integrated optical circuits coming soon? Posted: 11 Sep 2013 09:53 AM PDT An experimental demonstration of light scattering controlled by silicon nanoparticles augurs well for the development of integrated optical circuits.  |
| New system allows cloud customers to detect program-tampering Posted: 11 Sep 2013 08:47 AM PDT A new version of "zero-knowledge proofs" allows cloud customers to verify the proper execution of their software with a single packet of data.  |
| Airbrushing could facilitate large-scale manufacture of carbon nanofibers Posted: 11 Sep 2013 07:34 AM PDT Researchers have used airbrushing techniques to grow vertically aligned carbon nanofibers on several different metal substrates, opening the door for incorporating these nanofibers into gene delivery devices, sensors, batteries and other technologies.  |
| Map of galactic clouds where stars are born takes shape Posted: 11 Sep 2013 06:32 AM PDT Astronomers have completed the first stage of a map of the location of the most massive and mysterious objects in our galaxy -- the giant gas clouds where new stars are born. They identify the clouds -- which can be up to 100 light years across -- from the carbon monoxide they contain.  |
| Posted: 11 Sep 2013 06:31 AM PDT Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these "flash freezes" may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system.  |
