NASA orbiter finds new gully channel on Mars Posted: 22 Mar 2014 06:44 AM PDT A comparison of images taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter in November 2010 and May 2013 reveal the formation of a new gully channel on a crater-wall slope in the southern highlands of Mars.

Deep ocean current may slow due to climate change Posted: 21 Mar 2014 01:49 PM PDT Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet's climate.

Unique chromosomes preserved in Swedish fossil Posted: 21 Mar 2014 07:17 AM PDT Researchers have made a unique discovery in a well-preserved fern that lived 180 million years ago. Both undestroyed cell nuclei and individual chromosomes have been found in the plant fossil, thanks to its sudden burial in a volcanic eruption.

Now even more likely that there are particles smaller than Higgs out there Posted: 21 Mar 2014 06:53 AM PDT Nobody has seen them yet; particles that are smaller than the Higgs particle. However theories predict their existence, and now the most important of these theories have been critically tested. The result: The existence of the yet unseen particles is now more likely than ever.

Genetic factor contributes to forgetfulness Posted: 21 Mar 2014 06:50 AM PDT Misplaced your keys? Can't remember someone's name? Didn't notice the stop sign? Those who frequently experience such cognitive lapses now have an explanation. Psychologists have found a connection between such everyday lapses and the DRD2 gene. Those who have a certain variant of this gene are more easily distracted and experience a significantly higher incidence of lapses due to a lack of attention.

Humans can distinguish at least one trillion different odors Posted: 20 Mar 2014 11:07 AM PDT Humans are capable of discriminating at least one trillion different odors, new research shows. Scientists determined that our sense of smell is prepared to recognize this vast olfactory palette after testing individuals' ability to recognize differences between complex odors mixed in the laboratory. It has been said for decades that humans were limited to distinguishing only 10,000 different odors.

Computers see through faked expressions of pain better than people Posted: 20 Mar 2014 09:19 AM PDT Scientists have found that a computer system spots real or faked expressions of pain more accurately than people can. Humans could not discriminate real from faked expressions of pain better than random chance -- and, even after training, only improved accuracy to a modest 55 percent. The computer system attains an 85 percent accuracy.

WPA2 wireless security cracked Posted: 20 Mar 2014 07:08 AM PDT There are various ways to protect a wireless network. Some are generally considered to be more secure than others. Some, such as WEP (Wired Equivalent Privacy), were broken several years ago and are not recommended as a way to keep intruders away from private networks. Now, a new study reveals that one of the previously strongest wireless security systems, Wi-Fi protected access 2 (WPA2) can also be easily broken into on wireless local area networks (WLANs).
