Podcast: A blood test for concussions, how the hagfish escapes from sharks, and optimizing carbon storage in trees

This week, we chat about a blood test that could predict recovery time after a concussion, new insights into the bizarre hagfish’s anatomy, and a cheap paper centrifuge based on a toy, with Online News Editor David Grimm. Plus, Science’s Alexa Billow talks to Christian Koerner about why just planting any old tree isn’t the answer to our carbon problem.
