Neuroscientists identify key role of language gene Posted: 15 Sep 2014 12:39 PM PDT Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech.

Run, cheetah, run: New algorithm enables cheetah robot to run and jump, untethered, across grass Posted: 15 Sep 2014 08:45 AM PDT Speed and agility are hallmarks of the cheetah: The big predator is the fastest land animal on Earth, able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop.

Fracking: Gas leaks from faulty wells linked to contamination in some groundwater Posted: 15 Sep 2014 06:58 AM PDT A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source many people may have feared.

Martian meteorite yields more evidence of the possibility of life on Mars Posted: 15 Sep 2014 05:37 AM PDT A tiny fragment of Martian meteorite 1.3 billion years old is helping to make the case for the possibility of life on Mars, say scientists. The finding are of a 'cell-like' structure, which investigators now know once held water.

Schizophrenia not a single disease but multiple genetically distinct disorders Posted: 15 Sep 2014 05:35 AM PDT Schizophrenia isn't a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms, research shows. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness.

Brain inflammation dramatically disrupts memory retrieval networks, study finds Posted: 12 Sep 2014 08:25 AM PDT Brain inflammation can rapidly disrupt our ability to retrieve complex memories of similar but distinct experiences, according to scientists. The study specifically identifies how immune system signaling molecules, called cytokines, impair communication among neurons in the hippocampus, an area of the brain critical for discrimination memory. The findings offer insight into why cognitive deficits occurs in people undergoing chemotherapy and those with autoimmune or neurodegenerative diseases.

Clues to how giant elliptical galaxies move Posted: 12 Sep 2014 05:53 AM PDT New clues to how giant elliptical galaxies move have been discovered by an international team of astronomers. Elliptical galaxies have long been considered as essentially being made up of old stars that move randomly within them, like a swarm of bees. This has been challenged in many instances in the past ten-twenty years, but giant elliptical galaxies are still considered as a nearly round and non-rotating group of old stars by astronomers.

First graphene-based flexible display produced Posted: 10 Sep 2014 05:33 AM PDT A flexible display incorporating graphene in its pixels' electronics has been successfully demonstrated, the first time graphene has been used in a transistor-based flexible device.
