Stop pain at the cellular level
Researchers have discovered that making a few changes to an anti-nausea drug can create a long-lasting pain relief medication. Pain signaling occurs inside of our cells, rather than on the surface, which means that medication needs to be able to penetrate the cell’s membrane. The study, published in the Proceedings of the National Academy of Sciences, showed promising results that will help create more effective pain management drugs (NYU).
New treatments for eye disease may be right around the corner
Age-related macular degeneration affects part of the retina in your eye and blurs your central vision. It’s the leading cause of vision loss in Western countries, but we don’t have any effective treatments. Luckily, new research shows that melanin may be the answer we’ve been searching for. And though melanin becomes less effective as we age, researchers believe they can find a way to stimulate the pigment and stop macular degeneration in its tracks. The research is published in the Proceedings of the National Academy of Sciences (Yale University).
Curly hair has helped humanity survive
Humans evolved while living in very sunny, extremely hot climates. Researchers have discovered that our hair also evolved to help keep us from overheating. The study, published in Proceedings of the National Academy of Sciences, shows how tightly curled hair protected the scalp from solar radiation and reduced the need to sweat, which allowed humans to conserve water (Penn State).
