Astronauts to bring asteroid back into lunar orbit

Aug 7 2017

Future space exploration aims to fly further from Earth than ever before. New research examines the robotic phase of the Asteroid Redirect Mission (ARM). In addition to taking manned spaceflights deeper into space than ever before, the proposed mission would also bring some benefit for planetary science.

97 percent of insurance denials in pediatric proton patients overturned on appeal

Aug 7 2017

Insurance companies end up covering proton therapy treatment for pediatric cancer patients in 97 percent of the cases they originally deny once those decisions are appealed. Researchers analyzed five years of coverage decisions at Penn's Roberts Proton Therapy Center. They discovered that roughly one in 10 pediatric cancer patients are initially denied coverage for the cutting edge and costly treatment - yet nearly all patients ultimately get approval.

Pro-vaccine messages can boost belief in MMR myths, study shows

Current strategies for correcting misinformation about the dangers of vaccinations have the opposite effect and reinforce ill-founded beliefs, a study suggests.

Optical coherence tomography with XUV radiation at laboratory scale

Aug 7 2017

For the first time, physicists used extreme ultraviolet radiation (XUV) for this process, which was generated in their own laboratory, and they were thus able to perform the first XUV coherence tomography at laboratory scale. This radiation has a wavelength of between 20 and 40 nanometers - from which it is therefore just a small step to the X-ray range.

Pharmacy service could save NHS £517.6m, finds study

Aug 7 2017

A scheme launched by the Department of Health in 2011 to help patients stick to their drug regimens has been so successful, that in its first five years, it will save NHS England £517.6m in the long-term, a team of health economists has found.

Neurobiology: Lessons by post

Aug 7 2017

Learning involves constant restructuring of nerve-cell connections. This requires specialized transport systems to ensure that these specific synapses can structurally and functionally be modified. One such delivery mechanism has now been characterized.
