Scientists use AI and nanotechnology to detect signs of life in space

A molecule’s shape can carry information that its chemical formula does not. Two amino acids may contain identical atoms yet arrange them as mirror images, a distinction that matters when scientists examine possible traces of life. Researchers at the University of Osaka have developed an electrical method for reading that molecular handedness one molecule at a time. Their system combines atomically pointed gold electrodes with machine learning to interpret the signals produced as molecules en...
