Daily briefing: Should the Stanford Prison Experiment be retracted more than fifty years on?
Briefly

Recent observations by NASA's Perseverance rover have identified dark-rimmed 'leopard spots' on Martian rocks, which might suggest past microbial activity. While researchers consider these markings as potential evidence of ancient life, they stress that definitive proof requires sample analysis on Earth. Perseverance has collected samples that may soon be sent back for more in-depth examination. This finding adds to the ongoing exploration of life's potential on Mars and highlights the importance of returning samples for future studies.
Dark-rimmed 'leopard spots' in a rock studied by NASA's Perseverance rover last year could be the remains of microbial activity on Mars.
Researchers treated the rings as 'an intriguing signal' of ancient Martian life, but emphasized that conclusive evidence requires analysis of samples on Earth.
