Jumping drops get boost from gravity

A decade ago a new idea was brought into the general scientific community—shedding water from condensers was more efficient by using surface tension to make microscopic water droplets "jump" off the surface. The idea took ...

How strong is the gravity on Mars?

The planets Earth and Mars have few things in common. Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational axes, affording each of them strong ...

New theory of deep-ocean sound waves may aid tsunami detection

Acoustic-gravity waves are very long sound waves that cut through the deep ocean at the speed of sound. These lightning-quick currents can sweep up water, nutrients, salts, and any other particles in their wake, at any water ...

Astronomers detect five new 'hot Jupiters'

(Phys.org)—Giant exoplanets, like the so-called 'hot Jupiters' that are similar in characteristics to the solar system's biggest planet and orbit very close to their host stars, are excellent targets for astronomers in ...
