From CERN Courier, April 13, 2017: It took decades for dark matter to enter the lexicon of particle physics. Today, explaining the nature and abundance of dark matter is one of the most pressing problems in the field. Fermilab and University of Chicago’s Dan Hooper and University of Amsterdam’s Gianfranco Bertone review the 80-year history.

I was about to leave one of the lab’s service buildings when in came someone like a streak of lightning.

Fermilab’s first Latin American scientists came to the lab in 1983, when four researchers from Brazil traveled across the equator to work on experiment E691. Carlos Escobar was one of them. It was the beginning of a collaboration spurred by a bold proposition by Director Leon Lederman.
