Scientists Identify Neurotransmitters That Lead to Forgetting

While we often think of memory as a way of preserving the essential idea of who we are, little thought is given to the importance of forgetting to our wellbeing, whether what we forget belongs in the "horrible memories department" or just reflects the minutia of day-to-day living.

Greater Purpose in Life May Protect Against Harmful Changes in the Brain Associated With Alzheimer’s Disease

Greater purpose in life may help stave off the harmful effects of plaques and tangles associated with Alzheimer's disease, according to a new study by researchers at Rush University Medical Center.

The study is published in the May issue of the Archives of General Psychiatry.

"Our study showed that people who reported greater purpose in life exhibited better cognition than those with less purpose in life even as plaques and tangles accumulated in their brains," said Patricia A. Boyle, PhD.

"These findings suggest that purpose in life protects against the harmful effects of plaques and tangles on memory and other thinking abilities. This is encouraging and suggests that engaging in meaningful and purposeful activities promotes cognitive health in old age."

Venus to Appear in Once-In-A-Lifetime Event

On 5 and 6 June this year, millions of people around the world will be able to see Venus pass across the face of the Sun in what will be a once-in-a-lifetime experience.

It will take Venus about six hours to complete its transit, appearing as a small black dot on the Sun's surface, in an event that will not happen again until 2117.

New Particle Discovered at CERN

Physicists from the University of Zurich have discovered a previously unknown particle composed of three quarks in the Large Hadron Collider (LHC) particle accelerator. A new baryon could thus be detected for the first time at the LHC. The baryon known as Xi_b^* confirms fundamental assumptions of physics regarding the binding of quarks.

'Sounds of Silence' Proving a Hit: World's Fastest Random Number Generator

Researchers at The Australian National University have developed the fastest random number generator in the world by listening to the 'sounds of silence'.

The researchers -- Professor Ping Koy Lam, Dr Thomas Symul and Dr Syed Assad from the ANU ARC Centre of Excellence for Quantum Computation and Communication Technology -- have tuned their very sensitive light detectors to listen to vacuum -- a region of space that is empty.

Scientists See Solution to Critical Barrier to Fusion

Physicists have discovered a possible solution to a mystery that has long baffled researchers working to harness fusion. If confirmed by experiment, the finding could help scientists eliminate a major impediment to the development of fusion as a clean and abundant source of energy for producing electric power.

New material shares many of graphene’s unusual properties

Graphene, a single-atom-thick layer of carbon, has spawned much research into its unique electronic, optical and mechanical properties. Now, researchers at MIT have found another compound that shares many of graphene’s unusual characteristics — and in some cases has interesting complementary properties to this much-heralded material.

Hinode and SOHO Paint an Asymmetrical Picture of the Sun

Approximately every 11 years the magnetic field on the sun reverses completely -- the north magnetic pole switches to south, and vice versa. It's as if a bar magnet slowly lost its magnetic field and regained it in the opposite direction, so the positive side becomes the negative side. But, of course, the sun is not a simple bar magnet and the causes of the switch, not to mention the complex tracery of moving magnetic fields throughout the eleven-year cycle, are not easy to map out.

James Cameron on Earth's Deepest Spot: Desolate, Lunar-Like

The Mariana Trench's Challenger Deep—the deepest point on Earth—looks as bleak and barren as the moon, according to James Cameron, who successfully returned just hours ago from the first solo dive to the ocean abyss. 
At noon, local time Monday (10 p.m. ET Sunday), the National Geographic explorer and filmmaker's "vertical torpedo" sub broke the surface of the western Pacific, some 200 miles (322 kilometers) southwest of Guam.
