Were Neanderthals a sub-species of modern humans? New research says no

Posted: 18 Nov 2014 11:16 AM PST

Researchers have identified new evidence supporting the growing belief that Neanderthals were a distinct species separate from modern humans (Homo sapiens), and not a subspecies of modern humans.

Spice up your memory: Just one gram of turmeric a day could boost memory

Posted: 18 Nov 2014 08:00 AM PST

Adding just one gram of turmeric to breakfast could help improve the memory of people who are in the very early stages of diabetes and at risk of cognitive impairment.

Training can lead to synesthetic experiences: Does learning the 'color of' specific letters boost IQ?

Posted: 18 Nov 2014 07:55 AM PST

A new study has shown for the first time how people can be trained to 'see' letters of the alphabet as colors in a way that simulates how those with synesthesia experience their world.

Gravity may have saved the universe after the Big Bang, say researchers

Posted: 18 Nov 2014 04:27 AM PST

Physicists may now be able to explain why the universe did not collapse immediately after the Big Bang. Studies of the Higgs particle -- discovered at CERN in 2012 and responsible for giving mass to all particles -- have suggested that the production of Higgs particles during the accelerating expansion of the very early universe (inflation) should have led to instability and collapse.

Virus devastating sea stars on Pacific Coast identified

Scientists have now explained the mysteriously sudden appearance of a disease that has decimated sea stars on the North American Pacific Coast.

Finding 'lost' languages in the brain: Far-reaching implications for unconscious role of infant experiences

Posted: 17 Nov 2014 01:43 PM PST

An infant's mother tongue creates neural patterns that the unconscious brain retains years later even if the child totally stops using the language, as can happen in cases of international adoption, according to a new joint study. The study offers the first neural evidence that traces of the "lost" language remain in the brain.

Climate change was not to blame for the collapse of the Bronze Age

Posted: 17 Nov 2014 01:41 PM PST

Scientists will have to find alternative explanations for a huge population collapse in Europe at the end of the Bronze Age as researchers prove definitively that climate change -- commonly assumed to be responsible -- could not have been the culprit.

Hiding in plain sight: Elusive dark matter may be detected with GPS satellites

Posted: 17 Nov 2014 12:47 PM PST

The everyday use of a GPS device might be to find your way around town or even navigate a hiking trail, but for two physicists, the Global Positioning System might be a tool in directly detecting and measuring dark matter, so far an elusive but ubiquitous form of matter responsible for the formation of galaxies.

The 'dirty' side of soap: Triclosan, a common antimicrobial in personal hygiene products, causes liver fibrosis and cancer in mice

Posted: 17 Nov 2014 12:46 PM PST

Triclosan is an antimicrobial commonly found in soaps, shampoos, toothpastes and many other household items. Despite its widespread use, researchers report potentially serious consequences of long-term exposure to the chemical.

Warmth, flowing water on early Mars were episodic

Posted: 17 Nov 2014 10:06 AM PST

There is ample evidence that water once flowed on the surface of ancient Mars. But that evidence is difficult to reconcile with the latest generation of climate models that suggest Mars should have been eternally icy. A new study suggest that warming and water flow on Mars were probably episodic and related to ancient volcanic eruptions.

Calorie-restricting diets slow aging, study finds

Posted: 17 Nov 2014 08:06 AM PST

Neuroscientists have shown that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in the brain.

Spiral laser beam creates quantum whirlpool

Posted: 17 Nov 2014 06:33 AM PST

Physicists have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons, hybrid particles that have properties of both matter and light and could link electronics with photonics.

Magic tricks created using artificial intelligence for the first time

Posted: 16 Nov 2014 06:10 PM PST

Researchers working on artificial intelligence have taught a computer to create magic tricks. The researchers gave a computer program the outline of how a magic jigsaw puzzle and a mind reading card trick work, as well the results of experiments into how humans understand magic tricks, and the system created completely new variants on those tricks which can be delivered by a magician.

Teens with earlier school start times have higher motor vehicle crash rates

Posted: 14 Nov 2014 03:11 PM PST

Teen drivers who start class earlier in the morning are involved in significantly more motor vehicle accidents than peers with a later high school start time, a study shows. The results underscore the importance of the 'Awake at the Wheel' campaign of the National Healthy Sleep Awareness Project.
