Massive Volcanic Eruptions Did Not Cause The Extinction Of Dinosaurs
Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a […]

Rate-induced Biosphere Collapse In The Daisyworld Model
There is much interest in the phenomenon of rate-induced tipping, where a system changes abruptly when forcings change faster than some critical rate. Here, we demonstrate and analyse rate-induced tipping […]

Safeguarding Earth’s Biodiversity By Creating A Lunar Biorepository
Earth’s biodiversity is increasingly threatened and at risk. We propose a passive lunar biorepository for long-term storage of prioritized taxa of live cryopreserved samples to safeguard Earth’s biodiversity and to […]

Extreme Heat Is Likely To Wipe Out Earth’s Mammals In The Distant Future
A new study shows unprecedented heat is likely to lead to the next mass extinction since the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.

A Fossil Fruit Shows Ancestors Of Coffee And Potatoes Survived The Cretaceous Extinction
The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple […]

Researchers Find Decrease In Molybdenum Preceded Ancient Mass Extinction On Earth
A decline in the element molybdenum across our planet’s oceans preceded a significant extinction event approximately 183 million years ago, new research from Florida State University shows.
