Research finds how diving mammals evolved underwater endurance
Scientists at the University of Liverpool have shed new light on how diving mammals, such as the sperm whale, have evolved to survive for long periods underwater without breathing.
Superconducting secrets solved after 30 years
(Phys.org) —A breakthrough has been made in identifying the origin of superconductivity in high-temperature superconductors, which has puzzled researchers for the past three decades.
Scientists create quick-charging hybrid supercapacitors
The dramatic rise of smartphones, tablets, laptops and other personal and portable electronics has brought battery technology to the forefront of electronics research. Even as devices have improved by leaps ...
Gel-based audio speaker demonstrates capabilities of ionic conductors, long thought limited in application (w/ Video)
In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music—it's the "Morning" prelude from Peer Gynt, played on an ionic speaker.
A billion holes can make a battery
Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage ...
WiTricity's wireless charging technology is coming soon to mobile devices, electric cars, and more
More than a century ago, engineer and inventor Nikola Tesla proposed a global system of wireless transmission of electricity—or wireless power. But one key obstacle to realizing this ambitious vision has ...
Hubble and Cassini get a 360-degree view of Saturn's auroras (w/ video)
(Phys.org) —NASA trained several pairs of eyes on Saturn as the planet put on a dancing light show at its poles. While NASA's Hubble Space Telescope, orbiting around Earth, was able to observe the northern ...
'Tribo-electric,' the buzzword of the future?
Out at sea, gentle waves provide power for thousands of homes. In cities, dancefloor moves generate electricity for nightclubs. In the countryside, hikers use leg power to recharge their phones.
