The consequences of removing the entire NSB stretch beyond the board itself. Without independent scientific oversight, the U.S. risks slowing life-changing research. Visit the link in bio to sign your support & email your MoCs, or go here: Sign 👉 zurl.co/2HYap Email 👉 zurl.co/nJTAL #NSB #Trump
The graphic contains a photo of the NSF flag and the red Stand Up for Science logo. The graphic reads: "Trump fired the entire National Science Board, Without the NSB there is: Less independent oversight of NSF operations, Fewer checks on the president's decisions on science, Less expert scientific guidence for Congress & the president, NSF less protected from political pressure. Let's change that, SIGN YOUR SUPPORT FOR NSB. LINK IN. BIO."

I could not be more excited about the PhD thesis research of the newly minted doctor in the Drennan lab: Dr. Andrea Marcano-Delgado. Congratulations Andrea - amazing job! Note: Cathy is wearing cyanocobalamin pink jacket and Andrea in more methylcobalamin inspired jacket.
