The spring of 2024 brought an odd burst of heat in March, a “false spring, ” before the air turned icy again.

A team of researchers from Japan and Germany discovered a way to make solar cells produce more useful energy than the light they absorb, reaching about 130 % efficiency. The trick involves a special molybdenum metal complex that can capture extra energy created by a process called singlet fission. I
The team that will circle the moon this year looks very different from the astronauts who first landed there in 1969. The group includes a woman, a person of color and a Canadian, reflecting the diversity of today’s space program. Commander Reid Wiseman, a 50‑year‑old former Navy captain and widowe
In adolescence, the brain’s “default mode, ” “central executive, ” and “salience” networks are thought to work together for social understanding. When these networks do not connect properly, people may find it hard to read others’ feelings or intentions. Researchers compared teens with autism spectr
