A new experiment on how rapidly atoms can tunnel through a barricade revives a physics debate about how time passes on the quantum scale.
Companies and universities have long relied on seminars to reduce racism, despite lackluster results. Maybe institution leaders can salvage the format.
Microbes are well known for working together in stressful environments. Scientists wanted to see how they would fare at a labyrinthine brain teaser.
A Toronto lab recycles carbon dioxide into more useful chemicals, using materials it discovered with artificial intelligence and supercomputers.
Fast laser pulses produce a shock wave in air that pushes water vapor aside. That clears channels in clouds for transmitting optical data from satellites.
Computer scientists reconstructed the image of a whole room using the reflection from a snack package. It’s useful for AR/VR research—and possibly spying.
