Frankenstein programmers test a cybersecurity monster

Posted: 27 Aug 2012 02:59 PM PDT

To catch a thief, you have to think like one. Computer scientists are trying to stay one step ahead of cyberattackers by creating their own monster. Their monster can cloak itself as it steals and reconfigures information in a computer program.

Neandertal's right-handedness verified, hints at language capacity

Posted: 27 Aug 2012 01:08 PM PDT

There are precious few Neandertal skeletons available to science. One of the more complete was discovered in 1957 in France, roughly 900 yards away from the famous Lascaux Cave. That skeleton was dubbed "Regourdou." Then, about two decades ago, researchers examined Regourdou's arm bones and theorized that he had been right-handed.

Oceanic mystery solved: Connection between 'monster larva' and unique species of shrimp

Posted: 27 Aug 2012 12:20 PM PDT

The origin of Cerataspis monstrosa has been a mystery as deep as the ocean waters it hails from. For nearly two centuries, researchers have tried to track down the larva that has shown up in the guts of other fish over time but found no adult counterpart. Until now.

Panda preferences influence trees used for scent marking

Posted: 27 Aug 2012 12:20 PM PDT

As solitary animals, giant pandas have developed a number of ways to communicate those times when they are ready to come into close contact. One means of this communication occurs through scent marking. A recent study indicates that pandas make clear and specific choices about what trees are used for scent marking.

Fossil skeleton of strange, ancient digging mammal clears up 30-year-old evolutionary debate

Posted: 27 Aug 2012 10:07 AM PDT

Shortly after dinosaurs like Tyrannosaurus and Triceratops went extinct, the Earth became filled with mammals only distantly related to those alive today. Until recently, one of these creatures, Ernanodon antelios, was only known from a single, highly distorted specimen that raised many questions about its habits and evolutionary relationships. Scientists have now described a second specimen of Ernanodon that sheds new light on this curious beast.

The role of genes in political behavior

Posted: 27 Aug 2012 09:24 AM PDT

Politics and genetics have traditionally been considered non-overlapping fields, but over the past decade it has become clear that genes can influence political behavior, according to a review. This paradigm shift has led to novel insights into why people vary in their political preferences and could have important implications for public policy.

Scientists discover nerves control iridescence in squid's remarkable 'electric skin'

Posted: 27 Aug 2012 08:33 AM PDT

Nerves in squid skin control the animal's spectrum of shimmering hues -- from red to blue -- as well as their speed of change, biologists have found. The work marks the first time neural control of iridescence in an invertebrate species has been demonstrated.

Light from self-luminous tablet computers can affect evening melatonin, delaying sleep

Posted: 27 Aug 2012 06:42 AM PDT

A two-hour exposure to electronic devices with self-luminous "backlit" displays causes melatonin suppression, which might lead to delayed bedtimes, especially in teens.

Laser beam as a '3-D painter' to grow biological tissue or to create micro sensors

Posted: 27 Aug 2012 04:41 AM PDT

With laser beams, molecules can be fixed at exactly the right position in a three dimensional material. The new method can be used to grow biological tissue or to create micro sensors.
