Advanced CO, CO₂, and O₂ sensors offer precise monitoring for HVAC, lab, medical, and air quality control systems ...

Oxygen fills the air today, but for most of Earth’s early history it barely existed. Scientists say the atmosphere did not hold steady oxygen until about 2.

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 ...

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 ...

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 ...

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 ...

Delayed diagnosis of fibrotic ILD leads to higher mortality rates and shorter overall survival, emphasizing the need for early clinical recognition. Supplemental oxygen therapy in fibrotic ILD ...

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.
