Summary

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. Listen to previous podcasts.
