Hannah Ritchie published an excellent analysis of the emissions of an electric car versus those of a second hand fossil car. When electricity generation is a mix of renewables, the production emissions of an electric car (mainly the battery) are overtaken by the emissions of a fossil car after the second year of driving.

Researchers at Carnegie Mellon University have developed a WiFi based human pose sensing system that can identify multiple people and their positions in a room using the phase and amplitude of the WiFi signal, filtered using machine learning models. The system can map the UV coordinates of body regions and is comparable to image based recognition systems.
Physicists at École Polytechnique in Palaiseau have successfully used lasers to guide lightning over a Swiss mountain. The lasers create a pathway of low density, ionized air that the lightning can follow.
