Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

Radiocarbon dating of deep-sea corals.

, 2002
Deep-sea corals are a promising new archive of paleoclimate. Coupled radiocarbon and U-series dates allow (super 14) C to be used as a tracer of ocean circulation rate in the same manner as it is used in the modern ocean.

Ancient DNA Reveals Limited Hunter‐Gatherer Ancestry in the Cerny Culture (Middle Neolithic, France) Despite Hunting‐Associated Practices

American Journal of Biological Anthropology, Volume 191, Issue 1, September 2026.
ABSTRACT The arrival of the Neolithic way of life in Europe is associated with the migration of Anatolian farmers and their admixture with local hunter‐gatherers. In the Paris Basin (Northern France), the Middle Neolithic Cerny culture (4700–4300 bce) combines agricultural practices with funerary items linked to hunting, suggesting a particular ...
