Belly Dancing = Fewer Body Image Hang-ups

Women who belly dance in their free time have fewer hang-ups about their bodies, according to a study led by Marika Tiggemann of Flinders University in Australia and published in September 2014 in the journal Sex Roles. The researchers found that most women who participate in this form of dancing do so because it is fun and because they get to perform interesting moves, not because they necessarily feel sexier while doing so.

Detecting Diabetic Retinopathy Before Vision Fails

A study published in the September 2014 issue of The FASEB Journal identifies a novel strategy to diagnose the leading cause of blindness in adults, diabetic retinopathy, before irreversible structural damage has occurred. This advance involves quantifying the early molecular changes caused by diabetes on the endothelium of retinal vessels. Using new probes developed by scientists, the researchers were able to distinguish the early molecular development of diabetic retinopathy.

Single-Dose Flu Drug Appears Safe and Effective

An analysis of phase 2 and phase 3 clinical trials shows that a single injected dose of the neuraminidase inhibitor (NAI) peramivir is safe and effective at alleviating influenza symptoms, including fever and viral shedding, when administered within 48 hours of the onset of symptoms. Researchers reported their findings in September 2014 at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Washington D.C., an infectious diseases meeting of the American Society for Microbiology (ASM).

Filling in Wrinkles Safely

In the quest for youth—or at least a more youthful appearance—women and men are seeking treatments to minimize laugh lines, crow's feet, and frown lines, as well as to plump up lips and cheeks. A popular treatment involves injecting dermal fillers into the face. In studies of FDA-approved dermal fillers, people generally report they are satisfied with the outcome of their treatments.

Stopping Aging via Remote Control

An anti-aging process that involves remote control of cells? It sounds like science fiction, but it’s getting closer to reality thanks to biologists from UCLA.

The scientists, working with fruit flies, remotely increased levels of a gene called AMPK. The gene, a crucial sensor of energy in cells, gets activated when cellular energy levels are low. Increasing the AMPK levels in the fruit flies’ intestines increased their lifespan to about eight weeks from the normal six; during that time they also stayed healthier longer.
