Don't let failing oxygen sensors compromise your engine's performance. O2 sensors are critical to emissions control on your car, SUV or truck. As the name implies, the O2 sensor (also called an ...

Finding oxygen in an exoplanet’s atmosphere is a clue that life may be at work. On Earth, photosynthetic organisms absorb carbon dioxide, sunlight, and water and produce sugars and starches for energy ...

Modern vehicles are pretty complicated pieces of tech. Apart from emissions and other vital functions, the engine control system relies heavily on several sensors to regulate performance. That is ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Today’s climate change pales in comparison with what happened as Earth gave birth to its oxygen-containing atmosphere billions of years ago. By analyzing clues contained in rocks, scientists at the ...

A recent study finds most critically injured patients can recover with less supplemental oxygen than has previously been suggested. When a critically injured patient is admitted to the hospital, how ...

NASA’s Ingenuity helicopter has captured much of the world’s attention, but an amazing new experiment, in which the Perseverance rover produced a tiny amount of oxygen, is equally deserving of praise.

The evaluation of new drugs designed to treat specific anemias should include a thorough understanding of underlying pathophysiology, with a focus on enhancing oxygen transport. In this concise review ...

The most common indication for the administration of supplemental oxygen is acute or chronic hypoxemia. Causes include pulmonary infection, chronic obstructive pulmonary disease (COPD), congestive ...
