Exploring the Potential and Evaluating Hydrocarbon Degradation by Novel Antarctic Dietzia and Pusillimonas Isolates From a Pristine Environment

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
The Antarctic Dietzia and Pusillimonas isolates were tested for bioremediation applications. Genomic analyses revealed the potential to degrade complex organic compounds, potential virulence factors and resistance genes. Physiological assays showed a wide range of adaptation to abiotic factors and sensitivity to different groups of antibiotics ...

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Discovery Prospects for a Supernova Signature of Biogenic Origin

, 2011
Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust.
