Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Isotope ratio mass spectrometry application for environmental investigations [PDF]
Stable isotope ratio mass spectrometry (IRMS) is a useful technique with a broad range of applications. Stable isotopes are important indicators of environmental changes (including climate), and can be used to explain the functioning of biogeochemical ...

Numerical studies of the two- and three-dimensional gauge glass at low temperature
We present results from Monte Carlo simulations of the two- and three-dimensional gauge glass at low temperature using the parallel tempering Monte Carlo method. Our results in two dimensions strongly support the transition being at T_c=0.
