Since sending the first human into space in the 1960s, the solution to one key challenge has remained elusive: the efficient and reliable production of oxygen in space. On the International Space ...

As a recent leap in green chemistry, scientists have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen -- at close to room temperature. By fine-tuning the structure ...

NASA's Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated ...

Oxygen therapy can help people with COPD breathe better and do daily activities with less difficulty. There are three types of oxygen therapy: compressed oxygen cylinders, liquid oxygen, and oxygen ...

FAA regulations (14 CFR 91.211) mandate supplemental oxygen for private pilots above 12,500 feet MSL (if over 30 mins), continuously above 14,000 feet MSL, and for all occupants above 15,000 feet MSL, ...

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...
