Portable MRI could aid wounded soldiers and children in the Third World

 Scientists are developing an ultra-low-field Magnetic Resonance Imaging
system that could be low-power and lightweight enough for forward
deployment on the battlefield and to field hospitals in the World's
poorest regions

Second generation "portable" MRI device uses low-power magnetic fields to image the brain and other soft-tissue anatomy.  

"Standard MRI machines just can't go everywhere," said Espy. "Soldiers wounded in battle usually have to be flown to a large hospital and people in emerging nations just don't have access to MRI at all.  We've been in contact with doctors who routinely work in the Third World and report that MRI would be extremely valuable in treating pediatric encephalopathy, and other serious diseases in children."

Scientists turn blood into nerve cells in pursuit of better pain relief

"As it stands, there's not a whole lot we know about pain. Where a tissue or blood sample can be drawn and studied, our nervous system comprising different kinds of cells running signals through complex piping around the body presents a difficult task for scientific research. But a new study details a technique that turns blood cells into different nerve cells, promising to improve our understanding of why things itch or burn. By extension, it is hoped that it could lead to new forms of pain relief that do away with unwanted side effects such as sleepiness or loss of concentration."

The research was published in the journal Cell Reports.

Although scientists are increasingly using pint-size satellites sometimes no larger than a loaf of bread to gather data from low-Eartho rbit, they have yet to apply the less-expensive small-satellite technology to observe physical phenomena far from terra firma. Jaime Esper, a technologist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, however, is advancing a CubeSat concept that would give scientists that capability.
