Dartmouth researchers have developed a cell phone-based tool that monitors tissue health by using a naturally occurring molecule to measure the oxygen level in cells. The tool could provide a simple ...

A team of chemists at the Korea Advanced Institute of Science and Technology has succeeded in pulling an oxygen atom from a molecule and replacing it with a nitrogen atom. In their study, published in ...

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that ...

For decades, scientists believed that nearly all oxygen on Earth is produced through photosynthesis — a process driven by sunlight and carried out by plants, algae, and cyanobacteria. According to ...
