Nanoplastics are far tinier - a single nanometre is just 0.000001 millimetres. For comparison, a human hair is approximately 80,000–100,000 nanometers wide.</p> Thu, 04 Jul 2024 17:50:18 +0000 frederique.mazerolle@mcgill.ca 310812 at /newsroom /newsroom/channels/news/15-minute-city-might-not-be-realistic-north-america-researchers-find-357769 <p>In the “15-minute city,” a concept popularized in Europe, everything a resident might need on a daily basis is a short walk or bicycle ride away.

Our eye gaze during conversations therefore reveals a wealth of information about our attention, intention, or psychological states.
