The energetic origins of life

(Phys.org) —Imagination is perhaps the most powerful tool we have for creating the future. The same might be said when it comes to creating the past, especially as it pertains to origin of life. Under what conditions did ...

Deep-sea volcanoes: Windows into the subsurface

Hydrothermally-active submarine volcanoes account for much of Earth's volcanism and are mineral-rich biological hotspots, yet very little is known about the dynamics of microbial diversity in these systems. This week in PNAS, ...

Living under pressure: Lessons from the cradle of life

Deep sea alkaline hydrothermal vents have been theorized to be a place where life could have originated. The elevated temperature, alkaline pH, and unique vent action concentrate minerals and create local energetic gradients ...

New organic compounds found in Enceladus ice grains

New kinds of organic compounds, the ingredients of amino acids, have been detected in the plumes bursting from Saturn's moon Enceladus. The findings are the result of the ongoing deep dive into data from NASA's Cassini mission.

NASA study reproduces origins of life on ocean floor

Scientists have reproduced in the lab how the ingredients for life could have formed deep in the ocean 4 billion years ago. The results of the new study offer clues to how life started on Earth and where else in the cosmos ...

Mars volcano, Earth's dinosaurs went extinct about the same time

New NASA research reveals that the giant Martian shield volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about ...
