For nearly half a century, Robert D. “Bob” McKeown has probed nuclear particles and educated rising generations of physicists. Now, the former deputy director for science at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility is being honored for his outstanding career contributions with the 2024 American Physical Society’s Division of Nuclear Physics (DNP) Distinguished Service Award.

A team led by Columbia Engineering researchers and collaborators report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These "all-optical" nanosensors are probed with light only and therefore allow for fully remote read-outs -- no wires or connections are needed.
