Innovation in spectroscopy could improve greenhouse gas detection

(Phys.org) —Detecting greenhouse gases in the atmosphere could soon become far easier with the help of an innovative technique developed by a team at the National Institute of Standards and Technology (NIST), where scientists ...

Turbulent flows in 2D can be calculated in new model

Turbulent flows have challenged researchers for centuries. It is impossible to predict chaotic weather more than a week in advance. Wind resistance on a plane or a car cannot be calculated precisely, since it is determined ...

Stellar winds

(PhysOrg.com) -- The Sun, glowing with a surface temperature of about 5500 degrees Celsius, warms the Earth with its salutary light. Meanwhile the Sun's hot outer layer (the corona), with its temperature of over a million ...

Study compares sound from exploding volcanoes with jet engines

New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and ...
