Underwater snow gives clues about Europa’s icy shell

A new study suggests Europa's ice shell could be orders of magnitude purer than previously thought due to the formation of frazil ice, which keeps salt in seawater. This could affect the ice's strength and heat transfer, making it crucial for understanding Europa's habitability.

Today’s heat waves feel a lot hotter than heat index implies

Researchers at UC Berkeley find that the traditional heat index, which calculates how hot it feels based on temperature and humidity, fails to account for physiological responses to extreme heat. The new study suggests that this underestimation can lead to increased stress on the human body, particularly in sweltering conditions.
