Cracks in Pluto's moon could indicate it once had an underground ocean

Posted: 13 Jun 2014 12:28 PM PDT

If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean ocean of liquid water, according to a new study.

Processed red meat linked to higher risk of heart failure, death in men

Posted: 12 Jun 2014 02:46 PM PDT

Men who regularly eat moderate amounts of processed red meat such as cold cuts (ham/salami) and sausage may have an increased risk of heart failure incidence and a greater risk of death from heart failure. Researchers recommend avoiding processed red meat and limiting the amount of unprocessed red meat to one to two servings a week or less.

New computer program aims to teach itself everything about any visual concept

Posted: 12 Jun 2014 12:27 PM PDT

In today's digitally driven world, access to information appears limitless. But when you have something specific in mind that you don't know, like the name of that niche kitchen tool you saw at a friend's house, it can be surprisingly hard to sift through the volume of information online and know how to search for it. Or, the opposite problem can occur -- we can look up anything on the Internet, but how can we be sure we are finding everything about the topic without spending hours in front of the computer? Computer scientists have created the first fully automated computer program that teaches everything there is to know about any visual concept.

Scientists discover link between climate change and ocean currents over 6 million years

Scientists have discovered a relationship between climate change and ocean currents over the past six million years after analyzing an area of the Atlantic near the Strait of Gibraltar, according to new research.

Unexpected origin for important parts of the nervous system

Posted: 12 Jun 2014 11:23 AM PDT

A new study shows that a part of the nervous system, the parasympathetic nervous system, is formed in a way that is different from what researchers previously believed. In this study a new phenomenon is investigated within the field of developmental biology, and the findings may lead to new medical treatments for congenital disorders of the nervous system.

Father's age influences rate of evolution: 90% of new mutations from father, chimpanzee study shows

Posted: 12 Jun 2014 11:23 AM PDT

The offspring of chimpanzees inherit 90 percent of new mutations from their father, and just 10 percent from their mother, a finding which demonstrates how mutation differs between humans and our closest living relatives, and emphasizes the importance of father's age on evolution.

Quantum computation: Fragile yet error-free

Posted: 12 Jun 2014 11:22 AM PDT

Physicists have experimentally encoded one quantum bit (qubit) in entangled states distributed over several particles and for the first time carried out simple computations on it. The 7-qubit quantum register could be used as the main building block for a quantum computer that corrects any type of error.

Why Diplodocus did not put all her eggs in one basket

Posted: 12 Jun 2014 05:51 AM PDT

If you thought the largest dinosaurs to have walked the earth produced the biggest eggs, you'd be mistaken. Scientists have discovered that both individual egg size and clutch size for the sauropods – which includes Diplodocus – were a lot smaller than might be expected for such enormous creatures.

'Trust hormone' oxytocin helps old muscle work like new, study finds

Posted: 10 Jun 2014 08:27 AM PDT

Oxytocin -- a hormone associated with maternal nurturing, social attachments, childbirth and sex -- plays a critical role in healthy muscle maintenance and repair, researchers report. It is the latest target for development as a potential treatment for age-related muscle wasting. A few other biochemical factors in blood have been connected to aging and disease in recent years, but oxytocin is the first anti-aging molecule identified that is approved by the Food and Drug Administration for clinical use in humans.
