The journal Icarus published a study this month that compared lunar crater counts by eight professionals with crowdsourced counts by volunteers. The professional crater counts varied by as much as a factor of two. Two of the professionals, both planetary scientists at Washington University in St. Louis, explain why they weren’t surprised.

Plants fine-tune the response of their cells to the potent plant hormone auxin by means of large families of proteins that either step on the gas or put on the brake in auxin’s presence. Scientists at Washington University have learned that one of these proteins, a transcription factor, has an interaction region that, like a button magnet, has a positive and negative face. Because of this domain, the protein can bind two other proteins or even chains of proteins arranged back-to-front.

More than two-dozen WUSTL students have been invited to attend Clinton Global Initiative University in Arizona this weekend. One team’s project would help loved ones connect after disasters. And graduate student DeAndrea Nichols was chosen to help open the meeting. WUSTL hosted last year’s event.

​More than a dozen dancers will debut nine original works by WUSTL student choreographers April 4-6 as part of “Young Choreographers Showcase.” The biennial concert takes place in the Annelise Mertz Dance Studio.

What’s a long-awaited threat, born of outer space and a danger to life as we know it? Why, it’s “The Intergalactic Nemesis,” of course. Part old-time radio play and part multimedia graphic novel, this unique science fiction serial returns to St. Louis with the first two parts of a planned “Nemesis” trilogy.

United Nations Secretary-General Ban Ki-moon met with Washington University in St. Louis’ McDonnell scholars earlier this month. During a spring break trip to New York, McDonnell Academy scholars also met a former Federal Reserve chairman and other leaders in media, politics and finance.​

Yehuda Ben-Shahar and his team at Washington University in St. Louis have discovered that some mRNAs have a side job unrelated to making the protein they encode. They act as regulatory molecules as well, preventing other genes from making protein by marking their mRNA molecules for destruction.
