/newsroom/taxonomy/term/1102/all en /newsroom/channels/news/astronomers-capture-radio-signal-distant-galaxy-344925 <p>How do stars form in distant galaxies? Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies. However, these signals become weaker the further away a galaxy is from Earth, making it difficult for current radio telescopes to pick up.</p> Fri, 13 Jan 2023 21:13:54 +0000 shirley.cardenas@mcgill.ca 288629 at /newsroom /newsroom/channels/news/what-rise-oxygen-early-earth-tells-us-about-life-other-planets-337051 <p>When did the Earth reach oxygen levels sufficient to support animal life? Researchers from Ă山ǿ¼é have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, eukaryotic ecosystems. Their findings represent the strongest evidence to date that extremely low oxygen levels exerted an important limitation on evolution for billions of years.</p> Mon, 24 Jan 2022 21:23:08 +0000 shirley.cardenas@mcgill.ca 284911 at /newsroom /newsroom/channels/news/2500-earth-could-be-alien-humans-334080 <p>To fully grasp and plan for climate impacts under any scenario, researchers and policymakers must look well beyond the 2100 benchmark. Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.</p> Tue, 12 Oct 2021 22:30:51 +0000 shirley.cardenas@mcgill.ca 279560 at /newsroom /newsroom/channels/news/new-theory-how-earths-crust-was-created-268001 <p>More than 90% of Earth’s continental crust is made up of silica-rich minerals, such as feldspar and quartz. But where did this silica-enriched material come from? And could it provide a clue in the search for life on other planets?</p> Wed, 03 May 2017 22:40:34 +0000 christopher.chipello@mcgill.ca 28078 at /newsroom /newsroom/olivia-jensen Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 23084 at /newsroom /newsroom/john-stix Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 23686 at /newsroom
