Propagating dimensions of light: Deforming versatile non-diffractive beams along the optical trajectory
The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, scientists have endeavore.....»»
Meet Hyperlight, Ars Technica’s new, even brighter “Light” mode
You asked, so we built it! Like many sites, apps, and operating systems, Ars Technica has both "Light" and "Dark" visual styles. They look great! But even the "Light" mode has dar.....»»
Vortex electric field discovery could impact quantum computing
A new vortex electric field with the potential to enhance future electronic, magnetic and optical devices has been observed by researchers from City University of Hong Kong (CityUHK) and local partners......»»
Observing gain-induced group delay between multiphoton pulses generated in a spontaneous down-conversion source
Spontaneous parametric down-conversion (SPDC) and spontaneous four-wave mixing are powerful nonlinear optical processes that can produce multi-photon beams of light with unique quantum properties. These processes could be leveraged to create various.....»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
Discovery of key protein complex shows evolution and adaptability of photosynthetic organisms
A team of researchers has revealed the structure of a modified and evolved version of Photosystem I (PS I), a key protein complex used by plants and cyanobacteria to convert sunlight into chemical energy. This discovery sheds light on the evolution a.....»»
Polarization photodetector that mimics desert ant offers pathway for more sensitive, miniaturized imaging systems
Polarization photodetectors (pol-PDs) have widespread applications in geological remote sensing, machine vision, and biological medicine. However, commercial pol-PDs usually require bulky and complicated optical components and are difficult to miniat.....»»
The Amazon rainforest as a cloud machine: How thunderstorms and plant transpiration produce condensation nuclei
The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measu.....»»
Dynamic tracking technique can reduce noise in gravitational-wave detectors to peer deeper into the cosmos
Researchers have shown that optical spring tracking is a promising way to improve the signal clarity of gravitational-wave detectors. The advance could one day allow scientists to see farther into the universe and provide more information about how b.....»»
Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Webb finds new galaxies in Spiderweb protocluster field
Using the NASA/ESA/CSA James Webb Space Telescope, an international team of astronomers have found new galaxies in the Spiderweb protocluster. Their characteristics shed light on the growth of galaxies in these large cosmic cities, with the finding t.....»»
Where to watch the 2024 Christmas Tree Lighting at Rockefeller Center

New study sheds light on when to stand out or fit in
When it comes to job interviews, conventional wisdom often suggests that standing out is key to securing a position—seemingly at odds with the general human tendency to conform. A new study by SFI Complexity Postdoctoral Fellow Katrin Schmelz and h.....»»
The TCL QM8 will light up your living room and is on sale for Cyber Week

Enzyme study sheds light on the molecular mechanism behind "sleepiness"
Recent research has observed that chemical modifications called phosphorylation of proteins in brain neurons dynamically regulate sleep and wakefulness. But the protein kinases that suppress sleep and the dephosphorylation enzymes that control sleep.....»»
The Touch Bar’s loyal fans have made a standalone successor inspired by Apple
The Touch Bar was a controversial Apple creation, to say the least. But the now-discontinued MacBook Pro feature is being revised, in a way, through a new Kickstarter campaign for a more versatile standalone product: the Flexbar. more….....»»
Study brings to light new picture of intimate relationships among older adults
Living apart together (LAT) is the way to go for U.K. couples over 60, according to new research by Lancaster University and University College London (UCL)......»»
Infrared detectors made from quantum dots—a keener eye for the invisible
What do motion detectors, self-driving cars, chemical analyzers and satellites have in common? They all contain detectors for infrared (IR) light. At their core and besides readout electronics, such detectors usually consist of a crystalline semicond.....»»
