A new study suggests that hydrogen cyanide, a highly poisonous chemical, could have played a key role in the origins of life by forming reactive ice crystals in extreme cold. Computer simulations show these crystals promote unusual chemical reactions that produce building blocks for life. The findings highlight the chemical potential of frozen environments, including those beyond Earth.

Scientists have observed atoms that remain motionless within liquid metals at high temperatures, influencing how materials solidify. Using advanced microscopy, researchers from the University of Nottingham and the University of Ulm captured this phenomenon in molten metal nanoparticles. The finding reveals a new hybrid state of matter with potential implications for catalysis and materials engineering.
