The atomic "Trojan Horse" could inspire a new generation of X-ray lasers and particle accelerators

PICTURE: This is a simulated representation of the Trojan horse technique for generating high-energy electron beams. A laser beam (red, left) removes electrons (blue dots) … view more Credit: Thomas Heinemann / University of Strathclyde How do researchers investigate nature at its most basic level? They build "super microscopes" that can resolve atomic and subatomic details. This does not work …

Wireless nanowire lasers absorb infrared light and emit blue light

Enlarge / This article is about lasers (not necessarily those pictured). Some of us are eagerly awaiting the Photonics Revolution, where photons band together to overthrow the tyranny of the electrons. One of the ongoing problems slowing down the revolution is light sources: you need a laser coupled to a circuit that does something. All this has to happen on …

Australian helicopters targeted by lasers in South China Sea

"Some helicopter pilots had lasers pointed at them from passing fishing vessels," Euan Graham of the Australian Strategic Policy Institute wrote on The Strategist blog. Graham told CNN South China Sea missions. Graham was aboard HMAS Canberra, a helicopter landing dock and flagship of the Royal Australian Navy, as it operates in the South China Sea and Indian Ocean on …

Powerful Lasers Produce Wild New Child of Ice Thought to Exist Inside Uranus

Scientists use high-energy lasers to create a new phase of ice leaching on Earth before-but which might exist in Neptune and Uranus. Water's structure allows it to freeze into many different crystalline forms (including ice -IX, which does not share the same properties as the Ice-IX from Kurt Vonnegut's Cat's Cradle ). Perhaps one of the strangest forms is superionic …

Powerful lasers create a wild new kind of ice that seems to exist in Uranus

Artistic depiction of superionic ice formed on the surface of a diamond. Image: Millot, Coppari, Hamel, Krauss (LLNL ) Scientists used high-energy lasers to create a new ice phase that was different from Earth's before-but that could exist deep in Neptune and Uranus , Due to the structure of the water, it can freeze to many different crystalline forms (including …

Lasers cause magnets to behave like liquids

Credit: CC0 Public Domain For years, researchers have been following a strange phenomenon: when you hit an ultrathin magnet with a laser, the magnetism suddenly becomes demagnetized. Imagine the magnet on your fridge. Now, CU Boulder scientists are studying how magnets recover from this change and regain their properties within a fraction of a second. According to a study published …

Notre-Dame Cathedral: This art historian used lasers to digitally map the structure. Now he could help save it

Andrew Tallon, art professor at Vassar College, used lasers to painstakingly scan the Cathedral in 2015, giving us an almost perfect digital replica of the gothic structure. His work could help architects and engineers rebuild after the fire on Monday. Tallon studied Gothic architecture and tried to understand how medieval construction workers built some of Europe's great cathedrals. So he …

US creates AI satellites that can dodge Chinese SPACE LASERS Science | news

Space exploration has always been militarily motivated. It was the Cold War that drove NASA and the Soviet Union to move objects into orbit. And 60 years later, the US is building autonomous satellites capable of avoiding the burgeoning threat of Chinese laser weapons. The US military has shown that its constellation of Earth-robbing satellites has a "chance of fighting". …
