Volcanic activity billions of years ago set the stage for Earth's oxygen-rich atmosphere, research suggests

Phys.org: Earth science - Mon, 03/10/2025 - 14:15
It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers, including those from the University of Tokyo, provide a mechanism to explain precursor oxygenation events, or "whiffs," which may have opened the door for this to occur.

Direct laser acceleration of Bethe-Heitler positrons in laser-channel interactions

Positron creation and acceleration is one of the major challenges for constructing future lepton colliders. On the one hand, conventional technology can provide a solution, but at a prohibitive cost and scale. On the other hand, alternative, reduced-scale ideas for positron beam generation could bri…

Earth's oldest impact crater was just found in Australia—exactly where geologists hoped it would be

Phys.org: Earth science - Sat, 03/08/2025 - 20:50
We have discovered the oldest meteorite impact crater on Earth, in the very heart of the Pilbara region of Western Australia. The crater formed more than 3.5 billion years ago, making it the oldest known by more than a billion years. Our discovery is published today in Nature Communications.
