Nearly perfect, ultrathin invisibility cloak could have wide practical applications
Metal surface can repel electric charges
Magnetic shell provides unprecedented control of magnetic fields
Magnetic bubbles behave differently than other magnetic defects (w/ video)
Researchers develop metamaterials able to control spread of light
Russian researchers find more evidence to support notion that lightning is caused by cosmic rays
New kind of cosmic flash may reveal something never seen before: Birth of a black hole
(Phys.org) —When a massive star exhausts its fuel, it collapses under its own gravity and produces a black hole, an object so dense that not even light can escape its gravitational grip. According to a ...
New experiments set to detect gravitational waves
Einstein's gravity theory passes toughest test yet: Bizarre binary star system pushes study of relativity to new limits
(Phys.org) —A strange stellar pair nearly 7,000 light-years from Earth has provided physicists with a unique cosmic laboratory for studying the nature of gravity. The extremely strong gravity of a massive ...
The Earth's center is 1,000 degrees hotter than previously thought
Scientists have determined the temperature near the Earth's centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models ...
Physicists find right (and left) solution for on-chip optics
(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize ...
Scientists spin photons to send light in one direction
(Phys.org) —Researchers at King's College London have achieved previously unseen levels of control over the travelling direction of electromagnetic waves in waveguides. Their ground-breaking results could ...
Massive galaxy had intense burst of star formation when universe was only 6 percent of current age
(Phys.org) —Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.
