Mountain hikes are invigorating. Crisp air and clear views can refresh the soul, but thin air presents an additional challenge for high-altitude birds. "All else being equal, bird wings produce less ...

Has anybody looked into whether or not altitude has a significant impact on the heat dissipation abilities of air cooling techniques? For example, the air density at sea level is 1.2286 kg/m^3, while ...

Clearly I'm not going to go out a MLB park and start hitting home runs. I'm also not going to put that park in a giant dome so that I can change the ambient humidity and other factors. No, that would ...

Knowing the air density outside of a spacecraft can have a substantial effect on its angle of descent and ability to hit a specific landing spot. But sensors that can withstand the harsh hypersonic ...

Scientists have discovered that the air in the atmosphere around us is heavier (more dense) than they had previously thought. Knowing this will enable scientists to measure the mass of objects more ...

Welcome to Weather Education Week @ Home! All week we are bringing parents and students interesting science experiments from the NBC10 First Alert Weather team -- and the Philadelphia Phillies! You ...
