Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly ...

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 ...

Long before Earth had oceans, continents, or life, tiny grains of organic matter were drifting through the cold reaches of ...
