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.....»»
Saturday Citations: All that sparkles is plastic; woke tree diversity; the gravitational basin in which we reside
This week, astronomers considered whether dark energy varies over cosmic timescales. Via neutron analysis, physicists revealed that some Early Iron Age swords were altered recently by swindlers in order to be more historically exciting. And a profess.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
Powerful and compact optical frequency combs provide unique opportunities
Remember those big, clunky machines needed for super precise light measurements? Those days are fading thanks to tiny devices called microcombs. These chips can do the same job, but on a much smaller scale, opening doors for new applications......»»
Harnessing quantum principles: Phased arrays within phased arrays for smarter, greener indoor optical wireless networks
Imagine a future where indoor wireless communication systems handle skyrocketing data demands and do so with unmatched reliability and speed. Traditional radio frequency (RF) technologies like Wi-Fi and Bluetooth are beginning to struggle, plagued by.....»»
Intra-molecular distances in biomolecules measured optically with Ångström precision
A team led by physicists Steffen Sahl and Stefan Hell at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen and the MPI for Medical Research in Heidelberg has succeeded in measuring distances within biomolecules using a light.....»»
Oxidative stress: How protein recycling protects against cell death
Researchers at LMU University Hospital have discovered a new molecular switch that protects against cell death......»»
Dark energy: Could the mysterious force we think of as constant actually vary over cosmic time?
,As I finished my Ph.D. in 1992, the universe was full of mystery—we didn't even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of these basic facts since the discovery of the cosmic.....»»
Novel etching technique enhances absorptivity of powders for metal 3D-printing
In a significant advancement for metal additive manufacturing, researchers at Lawrence Livermore National Laboratory (LLNL) and their academic partners have developed a technique that enhances the optical absorptivity of metal powders used in 3D prin.....»»
NASA terminal transmits first laser communications uplink to space
NASA's LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, has transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit......»»
Making micelles more effective for dye and drug dispersion through well-defined core-shell structures
Micelles are spherical molecular structures usually formed by amphiphilic molecules with block structure, which contain both hydrophilic and hydrophobic parts. The hydrophobic tails of these molecules cluster together to form a core, while the hydrop.....»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
Detecting Planck-scale dark matter by leveraging quantum interference
While various studies have hinted at the existence of dark matter, its nature, composition and underlying physics remain poorly understood......»»

"The Dark Knight" connection in "Joker: Folie à Deux" is laughably bad
"Joker: Folie à Deux" hints at the origins of Heath Ledger's Joker in "The Dark Knight." But who asked for this? Joker: Folie à Deux is an unfortunate hodgepodge of references to better, more interesting films, including musicals like T.....»»
Traces of antimatter in cosmic rays reopen the search for "WIMPs" as dark matter
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is......»»
Fused molecules could serve as building blocks for safer lithium-ion batteries
By fusing together a pair of contorted molecular structures, Cornell researchers have created a porous crystal that can uptake lithium-ion electrolytes and transport them smoothly via one-dimensional nanochannels—a design that could lead to safer s.....»»
