Many particle accelerators rely on superconducting radiofrequency components made of niobium. Nuclear physicists found that dissolving oxygen atoms a few micrometers into niobium greatly improves the performance of components made of the metal. Now, the researchers are perfecting a model using different processes for adding oxygen. The model helps to predict and optimize component performance.

Blood Bubbles Reveal Oxygen Levels #ASA181
November 29, 2021By
Researchers have developed microbubbles to acoustically detect blood oxygen levels, since the microbubble shells are altered by structural hemoglobin changes in response to oxygen. The gas filling of the microbubbles causes them to oscillate and vibrate when ultrasound is applied, scattering energy and generating an acoustic response that can be detected by a clinical ultrasound scanner. Preliminary results show a strong correlation between oxygen concentration and the acoustic bubble response.

Did Earth’s early rise in oxygen help multicellular life evolve?
May 19, 2021By
Researchers find that oxygenation of Earth’s surface is key to the evolution of large, complex multicellular organisms. If cells can access oxygen, they get a big metabolic benefit. However, when oxygen is scarce, it can’t diffuse very far into organisms, so there is an evolutionary incentive for multicellular organisms to be small to ensure most of their cells can still access oxygen.
