  • Titanium isotope measurements for chondrites, ancient terrestrial mantle-derived lavas and modern ocean island basalts imply the preservation of a primordial lower-mantle reservoir for most of Earth’s geologic history.

  • Measurable titanium isotope fractionation occurred during melt extraction from planetary mantle demonstrating titanium isotopes can serve as a tracer for oxygen fugacity of planetary mantle reservoirs, according to an analysis of ureilites, diogenites, shergottites, chassignite, and nakhlites.

  • The commercial production of green diesel suffers from the requirement for continuous sulfur replenishment to maintain catalytic activity. Here, the authors report a sulfur-free catalytic system that can efficiently produce green diesel from various feedstocks over long periods of operation.

  • The nucleosynthetic composition of silicon in meteorites indicates that material akin to early-formed differentiated asteroids must represent a major constituent of terrestrial planets such as Earth and Mars.

  • The abundances of isotopes in presolar grains are presumed to reflect their nucleosynthetic generation in stars. However, here Robert et al. report experimentally detected evidence of mass-independent fractionation of titanium, implying that titanium isotopic abundances in presolar grains may not be as representative as once thought.
