Newly identified galactic supercluster is home to the Milky Way

Posted: 03 Sep 2014 10:33 AM PDT

Astronomers using the Green Bank Telescope -- among other telescopes -- have determined that our own Milky Way galaxy is part of a newly identified ginormous supercluster of galaxies, which they have dubbed 'Laniakea,' which means 'immense heaven' in Hawaiian.

Direct brain-to-brain communication demonstrated in human subjects

Posted: 03 Sep 2014 07:56 AM PDT

In a first-of-its-kind study, an international team of neuroscientists and robotics engineers has demonstrated the viability of direct brain-to-brain communication in humans.

'Brightpoints': New clues to determining the solar cycle

Posted: 03 Sep 2014 07:47 AM PDT

Approximately every 11 years, the sun undergoes a complete personality change from quiet and calm to violently active. However, the timing of the solar cycle is far from precise. Now, researchers have discovered a new marker to track the course of the solar cycle -- brightpoints, little bright spots in the solar atmosphere that allow us to observe the constant roiling of material inside the sun.

Scientists discover how to 'switch off' autoimmune diseases

Posted: 03 Sep 2014 06:21 AM PDT

Scientists have made an important breakthrough in the fight against debilitating autoimmune diseases such as multiple sclerosis by revealing how to stop cells attacking healthy body tissue. Rather than the body's immune system destroying its own tissue by mistake, researchers have discovered how cells convert from being aggressive to actually protecting against disease.

Cockatoos go to carpentry school

Posted: 02 Sep 2014 05:53 PM PDT

Goffin's cockatoos can learn how to make and use wooden tools from each other, a new study has found. The discovery is thought to be the first controlled experimental evidence for the social transmission of tool use in any bird species.

Potential for 'in body' muscle regeneration, rodent study suggests

Posted: 02 Sep 2014 11:32 AM PDT

What if repairing large segments of damaged muscle tissue was as simple as mobilizing the body's stem cells to the site of the injury? New research in mice and rats suggests that "in body" regeneration of muscle tissue might be possible by harnessing the body's natural healing powers.

Scientists make diseased cells synthesize their own drug

In a new study that could lead to many new medicines, scientists have adapted a chemical approach to turn diseased cells into unique manufacturing sites for molecules that can treat a form of muscular dystrophy.

Ocean mappers discover seamount in Pacific Ocean

Posted: 02 Sep 2014 11:32 AM PDT

Scientists on a seafloor mapping mission have discovered a new seamount near the Johnson Atoll in the Pacific Ocean. The summit of the seamount rises 1,100 meters from the 5,100-meter-deep ocean floor. The seamount's impact remains unknown -- for now. It's too deep (its summit lies nearly 4,000 meters beneath the surface of the ocean) to be a navigation hazard or to provide rich fisheries. "It's probably 100 million years old," Gardner says, "and it might have something in it we may be interested in 100 years from now."

Possible neurobiological basis for tradeoff between honesty, self-interest

Posted: 02 Sep 2014 08:42 AM PDT

What's the price on your integrity? Tell the truth; everyone has a tipping point. We all want to be honest, but at some point, we'll lie if the benefit is great enough. Now, scientists have confirmed the area of the brain in which we make that decision, using advanced imaging techniques to study how the brain makes choices about honesty.

Why is stress more devastating for some?

Posted: 02 Sep 2014 06:41 AM PDT

Some take stress in stride; others struggle with it, even developing psychiatric disorders. New research has identified the molecular origins of this so-called stress gap in mice. The results could contribute to a better understanding of the development of depression and other disorders brought on by stress.
