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.

Scientists discover new class of anti-diabetes compounds that reduce liver glucose production
A team of scientists has identified a new class of compounds that reduce production of glucose in the liver, which is linked to type 2 diabetes, the form of diabetes considered responsible for close to 95 percent of cases in the United States.

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?

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?

Drug development: Subtle steric differences reveal a model for Ni cross-coupling success
Researchers have developed a predictive model may enable challenging metal-catalyzed cross couplings reactions that are indispensable to drug development.

Cancer therapy: Tracking real-time proton induced radiation chemistry in water
Proton therapy is a promising form of radiation treatment used to kill cancerous cells and effectively halt their rapid reproduction, and the fundamental understanding for it is contained in the radiation induced water chemistry that occurs immediately after the interaction. The ensuing processes are therefore a subject of considerable scientific interest.

Cell biology: The quickest route to the tip for protein transport
According to a new theoretical model, in cell protrusions and cargo-transporting motor proteins often get in each other's way. The upshot is that freely diffusing proteins reach the leading edge faster.

Scientists discover mechanism that causes cancer cells to self-destruct
A new study reveals the role of three proteins in killing fast-duplicating cancer cells while they're dividing. The research finds that these proteins can be specifically modified to unleash an inherent 'death mechanism' that self-eradicates duplicating cancer cells.

Rare genetic forms of obesity more numerous, diverse than previously thought
In their search of seven databases and analysis of 161 papers, researchers found that 79 obesity syndromes have been previously reported. Of the 79 syndromes, 19 have been genetically solved, to the point where a lab test could confirm a doctor's suspicions. Another 11 have been partially clarified, and 27 have been mapped to a chromosomal region. For the remaining 22 syndromes, neither the gene(s) nor the chromosomal location(s) have yet been identified.
