Unlocking the Secrets of Nerve Regeneration

Nerves in the central nervous system of adult mammals do not usually regenerate when injured. The granule cell, a nerve cell located in the cerebellum, is different. When its fibres, called parallel fibres, are cut, rapid regeneration ensues and junctions with other neurons called "synapses" are rebuilt. The precise mechanism for this was unclear.

New Clues About the Aging Brain's Memory Functions

118700_web.jpg

A European study led by Umeå University Professor Lars Nyberg, has shown that the dopamine D2 receptor is linked to the long-term episodic memory, which function often reduces with age and due to dementia. This new insight can contribute to the understanding of why some but not others are affected by memory impairment. The results have been published in the journal PNAS.

Asteroid Day Will Draw Eyes to the Stars, but the More Urgent Threat May Be Under Our Feet

Knowing when an asteroid could impact Earth would be nice, but learning more about the impact a super volcano eruption at Yellowstone would have on civilization — and how to be ready for it — might be more prudent.

Skype Data of 500 Million People Reveals the Real Patterns of Social Adoption

Global patterns of adoption spreading are induced by local adoption cascades initiated by multiple spontaneous adopters arriving at a constant rate, amplified by a large number of adoptions induced by social influence, and controlled by individuals who are immune to the actual adoption.

“The Anonymous People” Documentary: 25 Million Americans Will No Longer Be Quiet

Current public perceptions about alcohol- and other drug-use disorders are out of step with scientific knowledge. There remains a general belief that these disorders are essentially moral failings and/or bad choices. This view is completely at odds with research demonstrating that these disorders are indeed a brain disease. A documentary called “The Anonymous People” features personal narratives that call for a fundamental reframing of the national conversation about alcohol and substance-use disorders and recovery.

Penguin Population Could Drop 60% by End of the Century

penguins1.jpg

University of Delaware researchers project that approximately 30 percent of current Adélie penguin colonies may be in decline by 2060 and approximately 60 percent may be in decline by 2099. The declines are associated with warming - many regions of Antarctica have warmed too much and further warming is no longer positive for the species.
