Dark molecular isomers lit up using optical cavities
In chemistry, molecules are manipulated by changing the constituent atoms, or their arrangements. Now a group of physicists and chemists from The City College of New York and Spain can demonstrate how the use of an optical cavity (where light is trap.....»»
New work sheds light on nonlinear encoding in diffractive optical processors based on linear materials
UCLA researchers have conducted an in-depth analysis of nonlinear information encoding strategies for diffractive optical processors, offering new insights into their performance and utility. Their study, published in Light: Science & Applications, c.....»»
When searching for light and a mate in the deep, dark sea, male dragonfish grow larger eyes, scientists discover
A small but ferocious predator, the male dragonfish will apparently do anything for love. Or at least to find a mate. A study by researchers at Boston College found that the eyes of the male dragonfish grow larger for mate-seeking purposes, making th.....»»
"Dark leadership" is a threat to Canada"s tourism industry, say researchers
It's summer and that means high season and busy times for the tourism sector. According to the United Nations World Tourism Organization, more than 285 million tourists traveled internationally from January to March 2024, an increase of about 20% com.....»»
New technique streamlines synthesis of heavy element compounds
Molecular compounds with heavy elements, like americium, curium and others can now be synthesized in a streamlined and efficient way thanks to a new technique developed by Lawrence Livermore National Laboratory (LLNL) researchers......»»
Sensing ultraviolet light with the help of molecular switches
The old saying "the dose makes the poison" also holds true for ultraviolet (UV) light. While UV light is essential for vitamin D production, it is also important in phototherapy, several industrial processes, and plant growth. It also has harmful eff.....»»
Astrophysicists uncover supermassive black hole/dark matter connection in solving the "final parsec problem"
Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles......»»
AI-powered optical detection to thwart counterfeit chips
The semiconductor industry has grown into a $500 billion global market over the last 60 years. However, it is grappling with dual challenges: a profound shortage of new chips and a surge of counterfeit chips, introducing substantial risks of malfunct.....»»
New tractor beam technology could one day minimize biopsy trauma
Researchers at TMOS, the ARC Center of Excellence for Transformative Meta-Optical Systems, have taken an important first step in the development of metasurface-enabled tractor beams—rays of light that can pull particles toward it, a concept that fi.....»»
New technique to diagnose cancer metastasis uses origami nanoprobes
Johns Hopkins engineers have created a new optical tool that could improve cancer imaging. Their approach, called SPECTRA, uses tiny nanoprobes that light up when they attach to aggressive cancer cells, helping clinicians distinguish between localize.....»»
Scientists uncover the molecular mechanism behind pineapple peel coloration
Pineapple peel coloration, especially the red hue, significantly enhances its commercial and aesthetic value. However, the genetic mechanisms driving this trait are not well understood, complicating breeding efforts for red-skinned varieties......»»
Opening up new ground in the search for dark matter
A new kind of detector for dark matter has the potential to make a direct detection of the enigmatic material, according to an analysis by RIKEN physicists......»»
Ground conditions can impact lunar swirls, study finds
Differences between the bright and dark patches in lunar swirls goes beyond the albedo variations; it includes differences in the structure of the lunar soils and the grains within those soils......»»
Scientists unveil cosmic fingerprints of sulfur rings
For the first time, a team of scientists from HFML-FELIX at Radboud University has unveiled the cosmic fingerprints of sulfur rings. These results, published in Nature Communications, may shed new light on the way sulfur was transported from dark int.....»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
An international team led by scientists at City University of Hong Kong has found a flexible metal-organic framework (MOF) with one-dimensional channels that acts as a "molecular trapdoor" to selectively adsorb gases, such as carbon dioxide, in respo.....»»
Engineers build optical elements for the Coronagraph Instrument of the Roman Space Telescope
Engineers and scientists of the Max Planck Institute for Astronomy (MPIA), led by Oliver Krause, developed crucial optical elements for the Coronagraph Instrument (CGI) of the Roman Space Telescope and delivered them to the Jet Propulsion Laboratory.....»»
New compact camera module for M5 MacBooks expected in 2025
Apple has reportedly commissioned one of its Vietnamese suppliers, Sunny Optical, to provide a new MacBook compact camera module (CCM) from next year. This is likely to be first used in an M5 MacBook Pro in late 2025. It’s a somewhat surprising.....»»
Interdisciplinary approach provides new insights into molecular mechanisms of cholera infection
Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells—more precisely, to certain "sugar lipids" (GM1 gangliosides, GM.....»»
