Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the ...

Limnology and Oceanography, Vol. 62, No. 6 (November 2017), pp. 2773-2787 (15 pages) Ecosystem metabolism of lakes strongly depends on the relative importance of local vs. allochthonous carbon sources ...

A team of researchers affiliated with multiple institutions in Japan has developed a technique for tracing the diffusion of carbon isotopes using atomic-scale vibrational spectroscopy. In their paper ...

Maya collapse wasn’t driven by drought alone, but by a cascading breakdown of interconnected political, social, and economic ...

Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...

Reliable carbonate carbon isotopes (δ 13 C carb) can reflect variations in global carbon cycling, and thus the paleoclimate and paleoceanographic conditions. However, significant depositional hiatus ...

The exact moment when Earth’s most catastrophic mass extinction ended the dinosaurs’ reign 65 million years ago has remained ...

A new study uses carbon isotope science to show that marked tusks in a seized ivory shipment were more than 30 years old and likely had found their way from a guarded government stockpile into the ...
