"The sounds of 'micro-lightning' have been recorded by NASA's Perseverance rover, ending a long search for the phenomenon on Mars."
"In total they found 55 such examples, along with signs of electrostatic interference indicative of the phenomenon."
"They dubbed the electric bursts 'micro-lightning', as they are far smaller than the lighting seen on Earth, due to the thin Martian atmosphere."
"A new analysis suggests that female authors retract fewer medical science papers than their male counterparts."
NASA's Perseverance rover captured sounds identified as 'micro-lightning', recording 55 events and signals of electrostatic interference. The bursts are much smaller than Earth's lightning because of Mars' thin atmosphere. Detection of these micro-discharges could refine understanding of Martian atmospheric chemistry and guide design of resilient surface exploration instruments. Other findings include biological parallels between male seahorse brood pouches and mammalian pregnancy and new insights into robust Neanderthal jaws. COP30 concluded in Brazil with mixed negotiation outcomes. An AI-assisted analysis found female authors appear on far fewer retracted medical science papers than male counterparts, with implications for research practices.
