How Young Genes Gain a Toehold on Becoming Indispensable
June 6, 2013 — Scientists have, for the first time, mapped a young gene’s short, dramatic evolutionary journey to becoming essential, or indispensable. The researchers detail one gene’s rapid switch to ... > full story -
Scientists Coax Brain to Regenerate Cells Lost in Huntington's Disease in Mouse Model
June 6, 2013 — Researchers have been able to mobilize the brain's native stem cells to replenish a type of neuron lost in Huntington's disease. The scientists were able to both trigger the production of new neurons ... > full story -
How Birds Lost Their Penises: Programmed Cell Death
June 6, 2013 — In animals that reproduce by internal fertilization, as humans do, you'd think a penis would be an organ you couldn't really do without, evolutionarily speaking. Surprisingly, though, most birds do ... > full story -
