July 2, 2014 — In the cover story of the latest issue of ASBMB Today, science writer Rajendrani Mukhopadhyay explores a longstanding controversy over how much vitamin D is enough for good health. While the Institute of Medicine raised the recommended daily intake to 600 IUs in 2011, some say the limit should be increased more in light of mounting (but not yet conclusive) evidence that vitamin D does a lot more than promote bone health. In his final column as president, Jeremy Berg reflects on the ASBMB annual meeting and announces his new blog, Datahound. Our Perspectives section is full of commentary about careers. Check out Bill Sullivan’s open letter to his parents about becoming an academic researcher, blogger Prof-like Substance’s thoughts about being a “cool professor” and Andrew D. Hollenbach’s essay about what it means to be a successful mentor. Plus, learn about a two-part course on science communication taught by Thomas O. Baldwin at the University of California, Riverside.
