A laser-sighted toxic goo gun is killing feral cats in Australia
A device that kills feral cats by squirting their fur with toxic gel they lick off while self-grooming is being used to protect endangered Australian animals Source: https://www.newscientist.com/article/2223493-a-laser-sighted-toxic-goo-gun-is-killing-feral-cats-in-australia/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Physicists Irreversibly Split Photons By Freezing Them In a Bose-Einstein Condensate
Physicists from the University of Bonn and the University of Cologne have succeeded in cooling photons down to a Bose-Einstein condensate, causing the light to collect in optical “valleys” from which it can no longer return. The findings have been published in the journal Science. Phys.Org reports: A light beam is usually divided by being directed onto a partially reflecting mirror:…
New, ‘Hidden’ State of Matter Coaxed into Being by Ultrafast Laser Flashes
Physicists think this might be the first of many hidden states of matter that could be uncovered using laser flashes. Source: https://www.livescience.com/laser-flash-crystal-new-phase-matter.html
Physics Experiment With Ultrafast Laser Pulses Produces a Previously Unseen Phase of Matter
An anonymous reader quotes a report from Phys.Org: Adding energy to any material, such as by heating it, almost always makes its structure less orderly. Ice, for example, with its crystalline structure, melts to become liquid water, with no order at all. But in new experiments by physicists at MIT and elsewhere, the opposite happens: When a pattern called a charge…
With a Laser, Researchers Say They Can Hack Alexa, Google Home or Siri
Researchers in Japan and at the University of Michigan said Monday that they have found a way to take over Google Home, Amazon’s Alexa or Apple’s Siri devices from hundreds of feet away by shining laser pointers, and even flashlights, at the devices’ microphones. The New York Times reports: In one case, they said, they opened a garage door by shining…
Researchers Transmit Energy With A Laser In ‘Historic’ Power-Beaming Demonstration
“First the first time, hundreds of watts of power were wirelessly transmitted hundreds of meters [video], with an integrated system that ensured the safety of operators and bystanders,” writes an anonymous Slashdot reader — sharing a new press release from the U.S. Naval Research Lab. “This could be the first step towards drones that never have to land…” According to the…
Extracting hidden quantum information from a light source
Current super-resolution microscopes or microarray laser scanning technologies are known for their high sensitivities and very good resolutions. However, they implement high light power to study samples, samples that can be light sensitive and thus become damaged or perturbed when illuminated by these devices. …
Weaving quantum processors out of laser light
An international team of scientists from Australia, Japan and the United States has produced a prototype of a large-scale quantum processor made of laser light. …
