If recent warnings of a stalemate war between Ukraine and Russia come to fruition, along with the West’s absent resolution for Ukraine’s win, Russian President Vladimir Putin will benefit above all, writes Jade McGlynn.
Information transfer in free space using ultraviolet, visible, or infrared waves has been gaining interest because of the availability of large bandwidth for high-data-rate communication. However, the presence of opaque occlusions or walls along the path between the transmitter and the receiver often impedes information transfer by blocking the direct line of sight.
In a new article published in Nature Communications, a team of researchers at UCLA Samueli School of Engineering and the California NanoSystems Institute, led by Dr. Aydogan Ozcan, the Chancellor’s Professor of Electrical & Computer Engineering, and Dr. Mona Jarrahi, the Northrop Grumman Endowed Chair at UCLA, has reported a fundamentally new method for delivering optical information around arbitrarily shaped opaque occlusions or walls.
This method permits the transmission of optical information, for example, images, around large and dynamically changing opaque occlusions. It is based on digital encoding at the transmitter and diffractive all-optical decoding at the receiver for transferring information around arbitrary opaque occlusions that completely block the direct line of sight between the transmitter and the receiver apertures.
A new study has unlocked a “backdoor” into the inner ear that could make administering gene therapies to restore hearing less risky.
Is the alternate timeline of ‘For All Mankind,’ leading to a better future? Here’s what the philosophy and atheistic of this sci-fi show is all about.
Four groups in the field of experimental psychology successfully replicate each other’s work by following best practices.
🔒 Yet another critical SQL injection vulnerability (CVE-2023–36934) uncovered in popular MOVEit Transfer—the same software that was exploited.
About 400 earthquakes have rumbled under Mount St. Helens since mid-July, the largest chain of shakes since the volcano finished erupting in 2008, the U.S. Geological Survey reported last week.
Small magnitude earthquakes, detected only by sensitive equipment, signal a volcano’s “recharging” as magma flows through chambers and cracks deep under the ground, said Wes Thelen, U.S. Geological Survey Cascades Volcano Observatory geophysicist and seismologist.
Between late August and early September, scientists observed 40 to 50 earthquakes per week located between 2.5 to 5 miles below the crater floor, before recently dwindling to 30. To compare, Mount St. Helens averaged roughly 11 quakes per month since 2008.
