Explained: Why water droplets 'bounce off the walls'

University of Warwick researchers can now explain why some water droplets bounce like a beach ball off surfaces, without ever actually touching them. Now the design and engineering of future droplet technologies can be made ...

Scientists 'film' a quantum measurement

Measuring a quantum system causes it to change—one of the strange but fundamental aspects of quantum mechanics. Researchers at Stockholm University have now been able to demonstrate how this change happens. The results ...

A possible new way to cool computer chips

A team of researchers at Stanford University has developed a theoretical way to cool down heated objects. In their paper published in the journal Physical Review Letters, the group describes their study of heat radiation ...

Engineers ensure quantum experiments get off to the right start

The quantum mechanical properties of electrons are beginning to open the door to a new class of sensors and computers with abilities far beyond what their counterparts based in classical physics can accomplish. Quantum states ...

Simple self-charging battery offers power solutions for devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved ...

Radio waves detect particle showers in a block of plastic

When neutrinos crash into water molecules in the billion-plus tons of ice that make up the detector at the IceCube Neutrino Observatory in Antarctica, more than 5,000 sensors detect the light of subatomic particles produced ...

Researchers create new state of light

For 20 years, researchers have studied how light rotates around a longitudinal axis parallel to the direction light travels. But could it move in other ways? After two years of research, and thanks to a sabbatical, University ...
