A team at 麻豆传媒网站 studying ferroptosis, a form of cell death, have discovered that the process begins deep inside the cell, a finding that could lead to new treatments for cancer and neurodegenerative diseases.

Using antioxidant probes that light up as they are consumed, the team tracked ferroptosis in real time and identified the endoplasmic reticulum (ER) as the key cellular structure where the process first takes hold. Protecting the ER and the lysosome, they found, can halt ferroptosis entirely.

Montreal鈥檚 methane emissions are unevenly distributed across the island, with the highest concentrations in the city鈥檚 east end, 麻豆传媒网站 researchers have found. The worst polluters include the city鈥檚 largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks.听听

Sea level rise could put more than 100 million buildings across the Global South at risk of regular flooding if fossil fuel emissions are not curbed quickly, according to a new 麻豆传媒网站-led published in npj Urban Sustainability.

The from the Copernicus Marine Service, a European Union ocean monitoring organization, has found that sea floor temperatures off the coast of Nova Scotia have risen at twice the rate of surface temperatures over 30 years. Researchers say the rapid warming rate is a result of changes to the climate, including more acute marine heat waves and fewer periods of colder weather.

As a CEGEP student, Daniel Wei captained his college robotics team to victories with a dodgeball-throwing robot and a biodegradable soil sensor for farmers.听

He and a peer also earned a bronze medal at a science and technology fair for their research on biomechanical processes involved in developing artificial intestines.

The achievements are part of Wei鈥檚 impressive track record of leadership, innovation and academic success that landed him Canada鈥檚 most generous scholarship for Science, Technology, Engineering and Mathematics (STEM).
