Scientists studying leaves from a 23-million-year-old forest have for the first time linked high levels of atmospheric carbon dioxide with increased plant growth, and the hot climate off the time.
The finding adds to the understanding of how…

Discovery Lays Blame on Supernova for Extinction Event Nearly 360 Million Years Ago
Between a decline in biodiversity and a series of extinction events, the Late Devonian period was not the most hospitable time on Earth.
And then came one or more supernovae explosions whose resulting ionizing radiation was the final push that…

Academics Develop New Method to Determine the Origin of Stardust in Meteorites
Meteorites are critical to understanding the beginning of our solar system and how it has evolved over time.
However, some meteorites contain grains of stardust that predate the formation of our solar system and are now providing important…

Inside the Ice Giants of Space
A new theoretical method paves the way to modelling the interior of the ice giants Uranus and Neptune, thanks to computer simulations on the water contained within them.
The tool, developed by scientists from SISSA in Trieste and the University of…

Innovative Method Opens up New Perspectives for Reconstructing Climatic Conditions of Past Eras
Corals precipitate their calcareous skeletons (calcium carbonate) from seawater. Over thousands of years, vast coral reefs form due to the deposition of this calcium carbonate.
During precipitation, corals prefer carbonate groups containing…

New Study Supports Predictions That the Arctic Could be Free of Sea Ice by 2035
A new study, published this week in the journal Nature Climate Change, supports predictions that the Arctic could be free of sea ice by 2035.
High temperatures in the Arctic during the last interglacial – the warm period around 127,000 years ago…
