Once frozen in time, worms come to life after 46,000 years

Scientists successfully revived a half-dozen worms that were buried in Siberian permafrost for 46,000 years in a state of suspended animation known as cryptobiosis, which halts metabolism and development until conditions improve. A type of nematode, or roundworm, the creatures were collected as part of permafrost samples taken about 130 feet underground in the early 2000s in eastern Russia. The worms were brought back to life in 2018 but more recent carbon dating helped pinpoint the age of the permafrost samples.

Spacecraft spies waves in Jupiter’s magnetosphere

Data from NASA’s Juno mission reveals massive swirling waves at the edge of Jupiter’s magnetopause, providing clues into how solar wind drives activity on the planet. “Kelvin-Helmholtz instabilities are a fundamental physical process that occurs when solar and stellar winds interact with planetary magnetic fields across our solar system and throughout the universe,” said Jake Montgomery, lead author of the study.
