SUNRISE Offers New Insight on Sun's Atmosphere

Posted: 27 Sep 2013 01:54 PM PDT

Three months after the flight of the solar observatory Sunrise – carried aloft by a NASA scientific balloon in early June 2013 -- scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere. Sunrise provided the highest-resolution images to date in ultraviolet light of this thin corrugated layer, which lies between the sun's visible surface and the sun's outer atmosphere, the corona.

Dynamics of Protein Synthesis at Neuron Tip is Basis for Memory and Learning

Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions. “Thousands of messenger RNAs reside in dendrites, yet the dynamics of how multiple dendrite messenger RNAs translate into their final proteins remain elusive,” says James Eberwine, PhD, professor of Pharmacology, Perelman School of Medicine at the University of Pennsylvania, and co-director of the Penn Genome Frontiers Institute.

Repurposed Antidepressants Have Potential to Treat Small-cell Lung Cancer

A bioinformatics approach to repurposing drugs resulted in identification of a class of antidepressants as a potential new treatment for small-cell lung cancer (SCLC), according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research.

Scientists Discover Important Wound-Healing Process

Scientists at The Scripps Research Institute (TSRI) have discovered an important process by which special immune cells in the skin help heal wounds. They found that these skin-resident immune cells function as “first responders” to skin injuries in part by producing the molecule known as interleukin-17A (IL-17A), which wards off infection and promotes wound healing.

New research from Karolinska Institutet and the Stockholm South General Hospital shows that the alpha-gal carbohydrate, which is found in the tick intestine, can cause allergic reactions to red meat in bitten people.
