Dinosaurs’ True Colors Revealed
Last year, researchers at Yale University discovered organelles called melanosomes on a 100-million-year-old dino feather. This year they will examine the shape and concentration of the melanosomes to determine the original colors of winged dinosaurs.
Feds Aim to Save Ecosystems
A new approach used by conservation biologists at the U.S. Fish and Wildlife Service highlights environmental trends to direct rescue funds toward bigger-picture causes, such as agricultural runoff, that affect not just single species but entire ecosystems.
Stem-Cell Science Gets Rebooted
Several groups have reprogrammed adult skin cells to behave like embryonic stem cells using genes ferried by viruses, a method that can cause the cells to become cancerous. This year’s goal: Replace viruses with chemicals that can do the job safely.

Elusive Black Hole Captured
Next year, astronomers will look into the heavens for evidence of the rare medium-size black hole. Studies will try to establish why they’re so scarce and will combine traditional visible-light astronomy with X-ray emissions from star clusters.
