Most life on Earth relies on the sun’s energy for survival, but what about organisms in the deep sea that live beyond the reach of its rays? A new study […]

Massive Asteroid Impacts Did Not Change Earth’s Climate In The Long Term
Two massive asteroids hit Earth around 35.65 million years ago, but did not lead to any lasting changes in the Earth’s climate, according to a new study by UCL researchers.
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 […]
The Eukaryome Of Modern Microbialites Reveals Distinct Colonization Across Aquatic Ecosystems
Protists are less studied for their role and diversity in ecosystems. Notably, protists have played and still play an important role in microbialites. Microbialites, or lithified microbial mats, represent the […]
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 […]
Self-sustaining Living Habitats In Extraterrestrial Environments
Standard definitions of habitability assume that life requires the presence of planetary gravity wells to stabilize liquid water and regulate surface temperature. Here the consequences of relaxing this assumption are […]
Life In The Atlantic Ocean Thrives Due To Windblown Saharan Dust
Iron is a micronutrient indispensable for life, enabling processes such as respiration, photosynthesis, and DNA synthesis. Iron availability is often a limiting resource in today’s oceans, which means that increasing […]
Earth’s Atmosphere: A Transport Medium Or An Active Microbial Ecosystem?
The atmosphere may be Earth’s largest microbial ecosystem. It is connected to all of Earth’s surface ecosystems and plays an important role in microbial dispersal on local to global scales. […]
What Doesn’t Kill Gaia Makes Her Stronger
Life on Earth has experienced numerous upheavals over its approximately 4 billion year history. In previous work we have discussed how interruptions to stability lead, on average, to increases in […]
Post-Impact Changes In Earth’s Ocean Ecology
Paleontologists have discovered a strange new species of marine lizard with dagger-like teeth that lived near the end of the age of dinosaurs.
