The reduced sunlight and lower vitamin D levels can lead to changes in mood, energy and sleep patterns. As well, the recent change back to standard time from daylight savings can disrupt circadian rhythms, with similar results.  </p> Wed, 20 Nov 2024 14:03:09 +0000 admin 1121 at /global-engagement /global-engagement/channels/news/expert-quebec-ban-heating-fossil-fuel-natural-gas-2040-361295 <p>The Quebec government recently announced its plan to prohibit heating homes with fossil-fuel natural gas by 2040 as part of its broader efforts to reduce greenhouse gas emissions and combat climate change. </p> <p>An expert from 91ÉçÇø is available to comment on this topic:  </p> Tue, 19 Nov 2024 19:25:17 +0000 admin 1120 at /global-engagement /global-engagement/channels/news/expert-war-ukraine-361288 <p>After receiving U.S. permission to do so, Ukraine is firing long-range missiles supplied by the United States into Russia for the first time, senior U.S. and Ukrainian officials have said.</p> <p><a href="/politicalscience/maria-popova"><b>Maria Popova</b></a><b>, Associate Professor, Jean Monnet Chair, Department of Political Science</b> at 91ÉçÇø is available to share her insights.</p> <p><span><span>Maria.popova</span> [at] <span>mcgill.ca</span></span> (English, Russian, Spanish)</p> Tue, 19 Nov 2024 16:06:49 +0000 admin 1118 at /global-engagement /global-engagement/channels/news/saskatchewans-first-centrosaurus-and-citipes-elegans-fossils-discovered-mcgill-researchers-361239 <p>Paleontologists and students from 91ÉçÇø have documented Saskatchewan's first confirmed fossil specimens of <i>Centrosaurus</i>, a horned dinosaur species closely related to <i>Triceratops</i>.</p> <p>The search, conducted in Saskatchewan Landing Provincial Park along the South Saskatchewan River, also unearthed a rare mix of dinosaur and marine fossils, shedding light on a dinosaur fauna which existed on the edge of an ancient sea at a time of rising sea levels long before humans roamed the earth.</p> Tue, 19 Nov 2024 12:36:54 +0000 admin 1116 at /global-engagement /global-engagement/channels/news/iasl-participates-roundtable-higher-airspace-operations-present-and-future-legal-point-view-361281 <p>The 91ÉçÇø Institute of Air and Space Law was delighted to participate in an expert roundtable on "Higher Airspace Operations: Present and Future from the Legal Point of View," co-hosted with the Permanent Mission of the Republic of Korea to ICAO at the Saint James's Club of Montreal.<br /> <br /></p> Tue, 19 Nov 2024 09:25:14 +0000 admin 1114 at /global-engagement /global-engagement/channels/news/new-technology-rapidly-measures-antioxidants-maple-syrup-361237 <p>Researchers at 91ÉçÇø have developed an eco-efficient, user-friendly technology that quickly measures the antioxidant content of maple syrup.
