Mechanistic basis of oxygen sensitivity in titanium

Titanium is extremely sensitive to small amounts of oxygen, which can lead to markedly decreased ductility of the material. Materials scientists therefore aim to lower the costs of purifying titanium, while avoiding the poisoning ...

Scientists reveal new clues into how Earth got its oxygen

For much of Earth's four and a half billion years, the planet was barren and inhospitable; it wasn't until the world acquired its blanket of oxygen that multicellular life could really get going. But scientists are still ...

Ultraviolet shines light on origins of the solar system

In the search to discover the origins of our solar system, an international team of researchers, including planetary scientist and cosmochemist James Lyons of Arizona State University, has compared the composition of the ...

Has Earth's oxygen rusted the Moon for billions of years?

To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon, according to a study published today in Science Advances led by Shuai Li, assistant researcher ...

Untangling a key step in photosynthetic oxygen production

Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists ...

Life might survive, and thrive, in a hydrogen world: study

As new and more powerful telescopes blink on in the next few years, astronomers will be able to aim the megascopes at nearby exoplanets, peering into their atmospheres to decipher their composition and to seek signs of extraterrestrial ...
