Researchers at McMaster University have developed a new menstrual health product designed to complement and enhance an existing menstrual cup that is safer, easier to use and more environmentally sustainable than current options.

Glaciers are fighting back against climate change by cooling the air that touches their surfaces. But for how long? The Pellicciotti group at the Institute of Science and Technology Austria (ISTA) has compiled and re-analyzed an unprecedented dataset of on-glacier observations worldwide. Their findings, published in Nature Climate Change, demonstrate that glaciers will likely reach the peak of their self-cooling power by the next decade before their near-surface temperatures spike up and melting accelerates.

Researchers have demonstrated a new and sustainable way to make the chemicals that are the basis of thousands of products – from plastics to cosmetics – we use every day.

In a new paper published today in Chem, a team of Columbia chemists has identified how to combine matter and light to get the best of both worlds: polaritons with strong interactions and fast, wavelike flow. These distinctive behaviors can be used to power optical computers and other light-based quantum devices.
