ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

What Future Lies Ahead for Circular Business Models Research?
ABSTRACT The circular economy—wherein waste is designed out, materials are circulated and nature is regenerated—has reached global recognition. From policy to business circles, it is seen as a viable strategy to address multiple societal grand challenges—including climate change and depletion of finite natural resources—and build a more resilient ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...
