NIH-Funded Research Makes Science’s “Top 10” List

NIH-funded AAAS/Science Editors' Choice for 2014 Breakthroughs of the YearModeled after Time’s Person of the Year, the journal Science has a tradition of honoring the year’s most groundbreaking research advances. For 2014, the European Space Agency nabbed first place with the Rosetta spacecraft’s amazing landing on a comet. But biomedical science also was well represented on the “Top 10” list—with NIH helping to support at least four of the advances. So, while I’ve highlighted some of these in the past, I can’t think of a better way for the NIH Director to ring in the New Year than to take a brief look back at these remarkable achievements!

Youth serum for real? Spanish explorer Ponce de Leon may have never discovered the Fountain of Youth, but researchers have engineered an exciting new lead. Researchers fused the circulatory systems of young and old mice to create a shared blood supply. In the old mice, the young blood triggered new muscle and more neural connections, and follow-up studies revealed that their memory formation improved. The researchers discovered that a gene called Creb prompts the rejuvenation. Block the protein produced by Creb, and the young blood loses its anti-aging magic [1]. Another team discovered that a factor called GDF11 increased the number of neural stem cells and stimulated the growth of new blood vessels in the brains of older animals [2].
