Author: Rachel Gordon, Massachusetts Institute of Technology In 1994, Florida jewelry designer Diana Duyser discovered what she believed to be the Virgin Mary’s image in a grilled cheese sandwich, which she preserved and later auctioned for $28,000. But how much do we really understand about pareidolia, the phenomenon of seeing faces and patterns in objects […]

Liquid crystals are all around us, from cell phone screens and video game consoles to car dashboards and medical devices. Run an electric current through liquid crystal displays (LCDs) and they generate colours, thanks to the unique properties of these fluids: rearrange their shape, and they reflect different wavelengths of light. As the lab of […]

Author: Leah Burrows, Harvard John A. Paulson School of Engineering and Applied Sciences The earliest blacksmiths in the Bronze and Iron Ages figured out that when they deformed metal through bending or hammering, it became stronger. This process, known as work or strain hardening, is still used widely in metallurgy and manufacturing today to increase […]

Researchers at the University of Toronto are using artificial intelligence to accelerate scientific breakthroughs in the search for sustainable energy. They have used the Canadian Light Source (CLS) at the University of Saskatchewan (USask) to confirm that an AI-generated “recipe” for a new catalyst offered a more efficient way to make hydrogen fuel . To […]

Freshwater scarcity affects over two billion people in the world, primarily in arid and remote regions, as well as islands and coastal areas without freshwater sources. Climate change and population growth are only making the problem worse, and existing methods require an energy input, usually electrical. Renewable energy can fix this and is required for […]
