Meet PitRanger: Tiny rover designed to probe the lunar underworld
Researchers have been busily building a prototype of a 33-pound (15 kg) lunar mini-robot, set to be the key instrument in a future mission aimed at capturing high-definition images of moon pits. Source: https://earthsky.org/space/meet-pitranger-a-tiny-rover-to-probe-lunar-underworld…
General anesthesia and normal sleep affect brain in an amazingly similar way as consciousness fades
What happens in the brain when our conscious awareness fades during general anesthesia and normal sleep? Scientists studied this question with novel experimental designs and functional brain imaging. They succeeded in separating the specific changes related to consciousness from the more widespread overall effects, and discovered that the effects of anesthesia and sleep on brain… Continue reading General anesthesia and normal sleep affect brain in an amazingly similar way as consciousness fades
Metasurface enabled quantum edge detection
Metasurfaces provide unique platforms to realize exotic phenomena including negative refraction, achromatic focusing, and electromagnetic cloaking due to the engineered dielectric or metallic architectures. The intersection of metasurfaces and quantum optics can lead to significant opportunities that remain to be explored. In a new report now published on Science Advances, Junxiao Zhou, Shikai Liu and a research team in quantum information,…
Neptune’s Weird Dark Spot Just Got Weirder
Neptune boasts some of the strangest weather in the solar system. The sun’s eighth planet holds the record for the fastest winds observed on any world, with speeds cutting through the atmosphere upward of 1,100 miles per hour, or 1.5 times the speed of sound. Scientists still don’t know exactly why its atmosphere is so tumultuous. Their latest glimpse of Neptune…
Capella Space Defends High-Resolution Satellite Photos Described as ‘Eerily Observant’
“A new satellite from Capella Space was described as “pretty creepy” by Bustle’s technology site Input: Like other hunks of metal currently orbiting Earth, the Capella-2 satellite’s onboard radar system makes it capable of producing ludicrously high-resolution visuals from its data. More unconventional is the service Capella has launched to match: the government or private customers can, at any time, request…
Researchers demonstrate nondestructive mid-infrared imaging using entangled photons
Researchers have shown that entangled photons can be used to improve the penetration depth of optical coherence tomography (OCT) in highly scattering materials. The method represents a way to perform OCT with mid-infrared wavelengths and could be useful for non-destructive testing and analysis of materials such as ceramics and paint samples. …
A surprising find of fast-moving gas from a young star

Fresh water reservoir discovered off Hawaii
A new imaging technique has provided an effective way to locate hidden undersea sources of drinking water. As things stand, most of the remote Pacific… Source: https://www.unexplained-mysteries.com/news/341218/fresh-water-reservoir-discovered-off-hawaii…
Pluto’s landscape more like Earth’s than previously thought
New analysis of data gathered from New Horizons’ 2015 flyby of Pluto shows evidence of Earth-like snow-capped mountains and the potential for glaciers made of methane ice. Source: https://earthsky.org/space/pluto-landscape-more-like-earths-than-previously-thought…
