InSight into Seismology on the Red Planet
Viking 2 detected two possible marsquakes in 1976. New analysis links one to the same region where InSight recorded nearly 1,000 marsquakes decades later.

The Ambiguous Costs of Climate Change
To put a price tag on climate change, some approaches focus on whether it made an event more likely, whereas others focus on whether it made an event more severe and damaging. A new study examines the validity of both approaches.

Clouds over the Highest Mountains Dance a Little Differently
Clouds over the Tibetan Plateau and the Andes are growing colder and higher than other clouds in response to climate change. That could affect local hydrology and radiation.
