From the room next door to the next planet over
The new Albert Chadwick Research Room inside the Roberts Proton Therapy Center is no ordinary laboratory space. In fact, there’s nothing else quite like it anywhere else in the United States, and whether it’s treating patients with cancer or helping NASA with its plans to send astronauts to Mars, the discoveries that could propel scientists forward will happen right here.

Microrna treatment restores nerve insulation, limb function in mice with MS
Scientists partially re-insulated ravaged nerves in mouse models of multiple sclerosis (MS) and restored limb mobility by treating the animals with a small non-coding RNA called a microRNA. In a new article, researchers report that treatment with a microRNA called miR-219 restarted production of a substance called myelin that is critical to normal function of the central nervous system.

Timing a space laser with a NASA-style stopwatch
To time how long it takes a pulse of laser light to travel from space to Earth and back, you need a really good stopwatch -- one that can measure within a fraction of a billionth of a second. That kind of timer is exactly what engineers have built at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for the Ice, Cloud and land Elevation Satellite-2.

The electric sands of Titan
Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.

Emotion: An important link to HIV prevention in black adolescents with mental illnesses
Could unique psychological factors that hamper emotional regulation help explain differences in HIV/STI risk-related sexual behaviors among heterosexually active black youth with mental illnesses?

More than 100 years of flooding and erosion in one event
Researchers have developed an integrated sediment, wood, and organic carbon budget for North St. Vrain Creek in the semi-arid Colorado Front Range following an extreme flooding event in September of 2013. Erosion of more than 500,000 cubic meters, or up to ~115-years-worth of weathering products, occurred through landsliding and channel erosion during this event.

Implementing large-scale teleretinal diabetic retinopathy screening program
Can a large-scale, primary care-based teleretinal diabetic retinopathy screening (TDRS) program reduce wait times for screening and improve the timeliness of care in the Los Angeles County Department of Health Services, the largest publicly operated county safety net health care system in the United States?

Friction shapes zebrafish embryos
The biochemical signals that give an embryo its shape have been studied extensively. The role of mechanical forces on the other hand is the subject of a new study. Here the researchers show that friction between moving tissues generates force. This force shapes the nervous system of the zebrafish embryo.
