TL;DR: Radiometric dating establishes the mass extinction that killed the dinosaurs as synchronous with a large asteroid impact between the Cretaceous-Paleogene boundary and associated mass extinctions with the Chicxulub bolide impact to within 32,000 years.

TL;DR: High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned.

Improvements in Mass Spectrometers for the Measurement of Small Differences in Isotope Abundance Ratios
TL;DR: A Nier-type mass spectrometer and its associated electronic units have been constructed for the purpose of measuring small variations in the abundances of oxygen and carbon isotopes to an accuracy of ±0.01 percent of the abundance of these isotopes.

Rare Gas Systematics in Popping Rock: Isotopic and Elemental Compositions in the Upper Mantle
TL;DR: New experimental data on the isotopic variations of neon, argon, and xenon in a popping rock imply that Earth accreted from planetesimals that probably underwent a transformation of their rare gas budget from solar- to chondritic-like, leaving the isotopy composition unchanged from the solar pattern.
