Extremophile enzyme activity lab: using catalase from Pyrobaculum calidifontis to highlight temperature sensitivity and thermostable enzyme activity

open access: yesJournal of Microbiology & Biology Education
There are places on earth that are considered to possess extreme physico-chemical characteristics as they relate to life. Surprisingly, there are microbes that have adapted various strategies that enable them to form robust communities in these ...

The Desert in Bottles: The Culturable Microbiome of the Atacama Desert's Grit Crust

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
The grit crust represents a unique biocrust type of the coastal Atacama Desert. Cyanobacteria, green algae and free‐living fungi were isolated along a fog gradient. Phylogenetic relationships indicated novel taxa and framed an indigenous microbiome. Microclimate and soil data support functional groups related to sites.

Intercomparison of methods for estimating leaf inclination angle distribution with terrestrial lidar for broadleaf tree species

open access: yesNew Phytologist, Volume 248, Issue 1, Page 415-430, October 2025.
Summary Leaf inclination angle distribution (LIAD) is a fundamental parameter of models that illustrate the energy and mass exchanges for vegetation at all scales. Terrestrial laser scanning (TLS) instruments have emerged as valuable tools for acquiring detailed measurements of canopy structure.

Microbial diversity and function in the rhizosphere microbiome: Driving forces and monitoring approaches

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract As an ecological unit, the rhizosphere microbiome preserves an enormous and largely unexplored diversity of microbes that play essential roles in plant health and soil functions. Omics technologies encompassing high‐throughput approaches such as metagenomics, metatranscriptomics, and metaproteomics provide helpful tools to unravel the ...

From Cosmos to Intelligent Life: The Four Ages of Astrobiology

open access: yes, 2012
The history of life on Earth and in other potential life-bearing planetary platforms is deeply linked to the history of the universe. Since life as we know it relies on chemical elements forged in dying heavy stars, the universe needs to be old enough ...
