Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters.

A bold claim that the deep ocean floor produces oxygen without any sunlight has drawn sharp scientific pushback, with critics ...

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 ...

Abstract: Transmission lines exposed to outdoors are susceptible to damage from environmental erosion, so regular defect inspection is required to ensure operational safety and stability for their ...

It’s National Sleep Awareness Month, and we can’t think of anything more helpful for sleep awareness than the best sleep ...

While fuel cells generate clean energy, fuel cell sensors generate precise measurements and are a gold standard for breath alcohol analysis.

Abstract: Miniature and multiparameter integrated water quality sensors are essential for marine environmental protection, resource exploration, and fisheries exploitation. This work describes a ...

AeroVironment, Inc. (“AV”) (NASDAQ: AVAV), a leading provider of advanced research and development solutions for national security missions, today announced it has been awarded a three-year, $97.4 ...

Cardiorespiratory fitness, as measured by peak oxygen uptake during cardiopulmonary exercise testing, is a prognostic indicator. We aim to predict peak oxygen uptake from submaximal variables on ...
