A very sad day for the Department of Chemistry as we mourn the death of Professor Dwight Seferos. Gone way too young.

Tell me you’re in Switzerland without saying so? Watching a dad push a baby carriage with one hand, with skis in the back of the carriage, while dragging his gear in the free hand. Wishing for a peaceful 2026. We could all use it.

Can’t think of a better way to get the wine ready for the Christmas Eve toast. Hotel Hermitage Cervinia @RelaisChateaux takes no chances.

A foggy, rainy, and cold day means a hearty powerful wine. Brunello 2015 San Giacomo hits the spot. The perfect end to a busy week of lectures including Nobel Laureate Akiro Yoshino, Tim Noel and David Nagib. Not a bad seminar program for a school north of the 49th parallel 😉
