Where did the energy come from to power the chemical origin of life, and how did phosphate come to be the universal energy currency of cells? Biologists from the Institute of Molecular Evolution at Heinrich Heine University Düsseldorf (HHU) have uncovered a new source of energy that drove primordial chemical reactions on the early Earth forward to kick-start metabolism. Their findings, now published in The FEBS Journal, identify phosphite and palladium, substances that naturally occur in H2-producing hydrothermal vents, as an inorganic precursor of ATP.

Crystal alignment explains why magnesium alloy plates resist ballistic impacts better in one direction
Magnesium (Mg) alloys offer a pathway to lighter, more efficient aerospace and defense structures because of their low density, high specific strength and excellent damping capacity. However, their hexagonal close-packed (HCP) crystal structure makes deformation highly dependent

Simulated moon soil and recyclable thermoplastics could help build future space infrastructure
Transporting material from Earth to the moon is an expensive proposition: By some estimates, moving a single kilogram (2.2 pounds) can cost more than $1 million. Any plan to build a permanent human habitat up there will depend on bringing that sky-high cost down.
