After an inspirational life that deeply touched many people, Geoff Lockwood passed away on Tuesday afternoon, January 20th, 2015. The family does not wish to have a memorial service. No flowers please. Geoff was a fervent believer and financial supporter of the United Way - so if you wish, a donation in Geoff's name would be greatly appreciated.

STI AWe are faced with convincing evidence that approximately a quarter of the universe is composed of something whose gravitational effects can be seen in a variety of astrophysical phenomena, but which we have been unable to detect and identify in the laboratory. Most physicists agree that this "dark matter" (DM) consists of new subatomic particle(s); the quest to discover its exact nature is among the foremost missions in modern physics and the greatest treasure hunts in history. Direct DM searches over the past few decades have been largely focused on Weakly Interacting Massive Particles in the ~10 GeV - 1 TeV mass range. The absence of any conclusive discovery, along with various theoretical developments and certain astrophysical observations, has recently motivated the direct detection community to broaden our experimental program to search for DM candidates in the <10 GeV mass range. Solid-state detectors provide many advantages for such searches. This talk will summarize recent advances in phonon- and ionization-based semiconductor crystal experiments such as SuperCDMS and EDELWEISS, cryogenic scintillating calorimeter experiments such as CRESST, and Charge-Coupled Device experiments such as DAMIC and SENSEI. It will also discuss future prospects and discovery potential for solid-state detectors with respect to various low-mass DM candidates, including dark photons, axion-like particles, and lightly-ionizing particles.
Professor Emeritus Art McDonald received the Nobel Prize in Physics on Thursday, December 10th in Stockholm along with co-winner Dr. Takaaki Kajita of the University of Tokyo.
During the Nobel Week (Dec 6 - 12), Dr. McDonald was busy with speeches and lectures. On Tuesday, December 8th, he gave his Noble Lecture on his research at Stockholm University.
To celebrate the research on the solar neutrino problem that led to the awarding of the 2015 Nobel Prize to Physics Professor Emeritus Arthur B. McDonald, two installations were unveiled on Monday April 16th in the Agnes Etherington Art Centre.
The first is a plinth that tells the fascinating story of the neutrino breakthrough that showed conclusively that neutrinos have mass. This plinth will be installed between Ontario Hall and Grant Hall and will be available year-round for students, and visitors to see.
