Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved by an international research group led by the Politecnic

Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved by an international research group led by the Politecnico di Milano, which has developed a new apparatus for studying ultrafast photochemical processes.

Researchers develop AI tool to map microRNA binding sites on circular RNAs

Circular RNAs (circRNAs) are loop-shaped molecules that can influence gene regulation through interactions with microRNAs (miRNAs). This matters because circRNAs can exist as different full-length isoforms, and their back-splice junction (BSJ) connects the two ends of the RNA. Tr

Birds are more afraid of women than men. Scientists have no idea why

Scientists have uncovered a strange pattern in urban bird behavior: Across five European countries and 37 species, birds consistently fled sooner when approached by women than men. Researchers have no clear explanation for the difference, raising intriguing questions about how bi
