SwRI models point to a potentially diverse metabolic menu at Enceladus
Using data from NASA's Cassini spacecraft, scientists at Southwest Research Institute (SwRI) modeled chemical processes in the subsurface ocean of Saturn's moon Enceladus. The studies indicate the possibility that a varied metabolic menu could support a potentially diverse microbial community in the liquid water ocean beneath the moon's icy facade. (2020-12-16)

Review examines sexual aggression in mammals
A recent review of published studies in non-human mammals examines 'sexual disturbance,' or male behavior towards a female around mating that can be costly for the female -- for example, that might inflict physical harm or cause mother-offspring separation. The findings are published in Mammal Review. (2020-11-18)

Measurements of Saturn's gravitational field show its rings are younger than the planet

Saturn hasn't always had rings
In its last days, the Cassini spacecraft looped between Saturn and its rings so that Earth-based radio telescopes could track the gravitational tug of each. Scientists in Italy and the U.S. have now used these measurements to determine the mass of the rings and estimate its age, which is young: 10-100 million years. This supports the hypothesis that the rings are rubble from a comet or Kuiper Belt object captured late in Saturn's history. (2019-01-17)
