UofT Physicist selected as part of team to lead major marine Arctic ecosystem study
The University of Toronto Mississauga (UTM), as a part of the Stantec Team, has been selected by an interagency scientific review panel to lead a long-term scientific study of the Arctic marine ecosystem along the Beaufort Sea shelf from Barrow, Alaska to the Mackenzie River delta in Canadian waters. The Marine Arctic Ecosystem Study (MARES) stems from increased attention to climate change, energy development, and sustainability in the Arctic region. Information gained will aid government, industry, and communities in making decisions related to regulations, resource management, economic development and environmental protection issues.

Solving the mystery of increased hydrogen chloride in the Northern Hemisphere
University of Toronto physicist Kaley Walker has helped solve the scientific mystery behind the recent increase in ozone-depleting chemicals in the lower stratosphere of the Northern Hemisphere, despite a 25-year old ban on chlorofluorocarbons (CFCs).
Employing data from various sources, including the Canadian Space Agency's SCISAT satellite, an international team of scientists used numerical simulations to determine that the recently observed increase in hydrogen chloride (HCl) in the lower stratosphere is due to reduced atmospheric circulation in the Northern Hemisphere.

‘Spintronics’ discovery could lead to better electronic devices
Scientists have discovered that interactions in certain quantum materials could naturally produce the effects needed for ultra-efficient computers and other electronics.The field of spintronics — a short form of spin transport electronics — seeks to understand and power electronic devices using the quantum property known as electron spin rather than an electron’s charge. Spintronics could lead to efficient circuits and electrical devices that do not waste energy through friction and heat.

Cracking mud, freezing dirt, and breaking rocks
Ordered crack patterns are so common in nature that they are often overlooked. From tile-like formations in ordinary mud, to the vast polygonal networks that stretch across the polar deserts of Earth and Mars, they are typical features in geomorphology. On smaller scales, crack networks add an artistic flourish to Japanese raku pottery and are found on the paintings of the old masters. Cracking even determines the pattern of scales on the snouts of Nile crocodiles.

Spontaneous spin Hall effect of ultracold atoms
Moving charges get deflected by a magnetic field, an effect which underlies such applications
as isotope separation and the quantum Hall effect which fixes the International standard
for electrical resistance.
