Looking for high-quality, smart reads on science? This Twitter list, put together by Scientific American's Khalil A. Cassimally will introduce you to lots of great, young science writers you might not have heard of previously. Some of the folks on the list whose awesomeness I can vouch for: freelancer David Manly, Smithsonian Magazine contributor Colin Schultz, blogger Hannah Waters, and Scientific American associate editor Ferris Jabr. Many new voices to discover!
