I generally try to avoid any type of discussion of the age of researchers and I also generally never ask people about their age. But this time it is in a story so I think it is OK to mention: Jack Gilbert of Argonne National Laboratory is on Crain’s Chicago 40 Under 40 2014 list. This 40 under 40 list is from Crain’s and focuses on people in Chicago and it is good to see them select a microbial ecologist as one of the honorees. Congrats Jack.
