Scientists at Boston Children’s Hospital, the Wyss Institute for Biologically Inspired Engineering at Harvard University and Boston University have developed a computer algorithm to test stem cells, a breakthrough that has allowed scientists to regrow part of a colon in a mouse. George Daley, professor of biological chemistry and molecular pharmacology at Boston Children’s Hospital, is quoted.
People in their 70s and beyond seem to need less sleep than they did when they were younger. New research from Beth Israel Deaconess Medical Center may finally explain why: They have lost sleep-promoting brain cells.

Hummingbirds evolved to prefer nectar when other birds lack the ability to perceive sweetness. Stephen Liberles, HMS associate professor of cell biology, is quoted.
What do our genetic contradictions mean? Do they play an important role in our biology? At this point, just about every genome scientist has a slightly different take. One surprising theory suggests that DNA diversity might be good for you. It’s a feature, not a bug. Christopher A. Walsh, Bullard Professor of Pediatrics and Neurology at Boston Children’s Hospital, is quoted.
In its first few years, national data shows Medicare Part D did help elderly Medicare beneficiaries make modest progress—they were better able to afford their medications and seniors were less likely to stop taking them for financial reasons.
