Understanding atmospheric pressure is vital, newsroom meteorologist Justin Ballard said, because those giant H’s and L’s representing high and low air pressure systems on a weather map are ...

The problem with traveling high into the atmosphere (and into space) is that you won't be able to use atmospheric oxygen ... low-thrust forms of propulsion like the ion engine.

Pale Blue plans to demonstrate its 1U water ion thruster twice in 2025 on D-Orbit’s Ion Satellite Carrier, an orbital transfer vehicle. The contract with D-Orbit includes two launch ...

Blood pressure and heart rate (pulse) are two important vital signs measured during a healthcare visit. Blood pressure (BP) is a measure of the force of blood on the blood vessel walls. Blood vessels ...

NASA's Jet Propulsion Laboratory (JPL) will soon start getting back to normal operations after weathering the raging L.A. fires. JPL lies at the base of the San Gabriel Mountains just north of Los ...

Propulsion pods are not a new product, but a new configuration of traditional marine systems and components. As yet, studies have not shown whether pods are more efficient than conventional shaft ...

Ion transport is the movement of ions across a membrane, passively through ion channels or actively through ion pumps such as symporters and antiporters. Iron and manganese are essential nutrients ...

Healthcare providers consider low blood pressure (hypotension)—a reading below 90/60 millimeters of mercury (mm Hg)—benign, or not harmful, because it rarely causes symptoms. However, some people with ...

Ion channels are integral membrane protein assemblies that modulate the flow of ions into and out of a cell or organelle, leading to generation of electrical signals. Opening (gating) of ion ...
