In a breakthrough for next-generation technologies, scientists have learned how to precisely control the behavior of tiny waves of light and electrons, paving the way for faster communications and quantum devices.
Metal oxides are abundant in nature and central to technologies such as photocatalysis and photovoltaics. Yet, many suffer from poor electrical conduction, caused by strong repulsion between electrons in neighboring metal atoms.
“ [K-9] Archer was not just a police dog; he was a partner, protector and a member of our police family,” Interim Police Chief Reed Mahuna said
Finding life beyond Earth would be a major scientific discovery with significant implications for all areas of science and human thought. Yet, only one direct search for extraterrestrial life has ever been conducted.
Officers found the man as he was fleeing the scene of a double shooting; he has since pleaded guilty to two counts of murder
Video shows Peoria PD officers speaking with a suspect and instructing him to put down a bat; as the officers approached him, the man jumped up and hit an officer with the bat
Since the early days of human space exploration, the endeavor has been haunted by a very good question: why spend so much on space when there are so many urgent problems here on Earth?
Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this “magic angle,” electrons move very slowly, which can lead to the emergence of highly correlated electron states.
Within our Milky Way galaxy, in the direction of the constellation Vulpecula, a cosmic “lighthouse” named PSR B1937+21 spins at an astonishing rate of 642 revolutions per second. It emits electromagnetic pulses that rival the precision of atomic clocks.
Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. With this upgrade, the MWA will continue to operate with much needed improvements while radio astronomy awaits the completion of the successor it helped enable—the Square Kilometer Array (SKA).
Space has a trash problem, with defunct satellites, rockets, and smaller broken bits orbiting Earth at high speeds. The amount of space junk is only increasing, raising the risk of collision with active satellites and spacecraft, according to Kazunori Takahashi, associate professor in the Graduate School of Engineering at Tohoku University in Japan. Takahashi may have a solution, though.
Using ESA’s INTEGRAL spacecraft, astronomers have detected exceptionally bright X-ray flares from the Cygnus X-1 X-ray binary system. This is the first time that such strong flaring activity has been observed in this system although it has been monitored for decades. The new findings were detailed in a paper published August 28 on the pre-print server arXiv.
Temperatures of more than 10,000°C and a hail of charged particles from the fusion fuel (plasma): These are extreme conditions that the exhaust wall (divertor) of future fusion power plants will need to withstand. It makes handling the exhaust stream one of the main challenges to realizing clean, safe and affordable commercial fusion power plants.
The injured officer was able to fend off the attacker; other cops pursued the man, firing shots after he lunged at another officer with the knife
“The smiles on the kids’ faces are really what make you realize that this is a great community outreach service,” said Lt. Kyle Besse of the Norwich PD
