Possible detection of hydrazine on Saturn's moon Rhea

In a new report on Science Advances, Mark Elowitz, and a team of scientists in physical sciences, optical physics, planetary science and radiation research in the U.S., U.K., India, and Taiwan, presented the first analysis ...

Spider-Man-style robotic graspers defy gravity

Specially designed vacuum suction units allow humans to climb walls. Scientists have developed a suction unit that can be used on rough surfaces, no matter how textured, and that has applications in the development of climbing ...

An optical coating like no other

For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings ...

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 ...

The four most promising worlds for alien life in the solar system

The Earth's biosphere contains all the known ingredients necessary for life as we know it. Broadly speaking these are: liquid water, at least one source of energy, and an inventory of biologically useful elements and molecules.
