Anak Krakatau, which means Child of Krakatoa, has been active sporadically since it emerged from the sea at the beginning of the last century in the caldera formed after the 1883 eruption of Mount Krakatoa.
Many of the common materials we encounter in our daily lives are crystalline, including ice, salt and sugar. The crystal structures of some solids are formed from molecules arranged in simple geometric patterns, and these ...
Researchers from The Australian National University (ANU) have engineered new optical coatings for LIGO, the global collaboration hunting gravitational waves from colliding black holes and neutron stars.
Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER ...
By superimposing two ultrashort laser pulses that converge from different directions, a team of physicists at the University of Oldenburg has succeeded in generating three-dimensional light fields.
Muons are constantly being created as cosmic rays collide with molecules in Earth's upper atmosphere. With their ability to penetrate far into dense, solid materials, these cosmic muons are often used to image the insides ...
An international team of physicists has developed a new method for determining the precise color of laser light using an image that rotates as the laser's frequency shifts.
University of Massachusetts Amherst's Jeff Podos and his former graduate student João C.T. Menezes have identified two contenders for the title of world's loudest bird: the bare-throated bellbird and the red-legged seriema. ...
There's big news from the quantum world. A quantum computer has been used in space for the first time. The device was aboard a spacecraft in low Earth orbit and demonstrated technology that could eventually help solve a problem ...
A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and telecommunications. Most devices are built to perform a particular job. If you want them to do something different, ...
