Nanoscale Fletching: Revolutionizing the Future of Non-Stick Cookware
by
-
Quick Answer: A cutting-edge innovation from the University of Toronto is reimagining non-stick cookware using a technique called nanoscale fletching—a chemical-minimizing, high-performance alternative to toxic Teflon coatings. What Is Nanoscale Fletching? Inspired by the aerodynamics of arrow feathers (aka “fletching”), scientists have applied this concept at the nanometer scale. Instead of actual feathers, they’ve built […]

Analysis: Trump’s tariffs could cut just 0.3% from global CO2 emissions in 2025
US president Donald Trump’s tariffs might only shave 0.3% off global carbon dioxide (CO2) emissions this year, according to Carbon Brief analysis. While the Trump administration is setting back international climate action through policies such as the “one big beautiful bill”, some analysts have argued that his tariffs would inadvertently cut carbon by throwing sand […]

What the Court Didn’t Say: The ICJ’s Climate Opinion and the Politics of Judicial Restraint
The advisory opinion of the International Court of Justice (ICJ) on the Obligations of States in Respect of Climate Change has already been hailed as a historic contribution to the evolving body of case-law on climate-related international law. The opinion was described as a “historic legal victory for small island states” who remain most vulnerable […]

Climate change could make ‘droughts’ for wind power 15% longer, study says
Extreme “wind droughts” that reduce power output from turbines for extended periods could become 15% longer by the end of the century across much of the northern hemisphere under a moderate warming scenario. That is according to a new study in Nature Climate Change, which explores how climate change could impact the length and frequency […]

New algorithms enable efficient machine learning with symmetric data
by
If you rotate an image of a molecular structure, a human can tell the rotated image is still the same molecule, but a machine-learning model might think it is a new data point. In computer science parlance, the molecule is “symmetric,” meaning the fundamental structure of that molecule remains the same if it undergoes certain […]
