Science Snapshots: August 16, 2026
This science roundup covers the climate benefits of switching to electric vehicles, the discovery of a rapidly growing supermassive black hole by the Webb telescope, and how mouse brains preserve memory clusters during hibernation.
Why it matters
These findings represent significant advancements in climate policy research, astrophysics, and neurobiology.
Never too soon to switch to an electric vehicle
Replacing a functional fossil-fuel vehicle with an EV is almost always better for the climate even if the former car is new, an analysis of lifecycle emissions has found. While manufacturing a new EV creates a carbon debt, it is usually paid back as lower emissions (while driving) within three years. Over time, retiring a gas car early and switching to an EV can reduce total carbon emissions by roughly 44% across cars, SUVs, and trucks.
