Gold nanoparticles that selectively emit left- or right-handed light
When chiral gold nanoparticles are irradiated with near-infrared femtosecond pulses, visible emission of luminescence is observed. In a study published in Advanced Optical Materials, this luminescence was found to yield high selectivity for left- or.....»»
Egypt tomb find may shed light on ancient diseases: Ministry
A new discovery of 33 ancient tombs in Egypt's southern city of Aswan could reveal "new information on diseases" prevalent at the time, the tourism and antiquities ministry said Monday......»»
Researchers develop tuneable anti-counterfeiting material
Counterfeiters are becoming increasingly more sophisticated in forging everything from diplomas and currency to medications and artwork. While protective measures such as luminescent markings (which glow under ultraviolet light) have been around for.....»»
California lawmakers reject proposal to curb well-drilling where nearby wells could run dry
Over the past several years, California's water managers have seen a pattern emerge in farming areas of the Central Valley: Even as declining groundwater levels have left thousands of residents with dry wells and caused the ground to sink, counties h.....»»
Scientists explore the vast reservoir of dissolved organic matter in oceans
Few things last very long in the world of the open oceans, it would seem. In the light-filled surface layer, microscopic algae convert carbon dioxide and water into biomass via photosynthesis. Individual cells vanish in a matter of hours or days, ing.....»»
Report: Cheaper ‘Apple Vision’ headset could require a tethered iPhone or Mac
Earlier this week, a report suggested that Apple has shifted its focus from developing a next-generation Vision Pro to a lower-cost version of the headset instead. A new report today sheds more light on the Apple Vision product roadmap, with some det.....»»
The Mokibo Fusion 2.0 is unlike any iPad keyboard I’ve ever used
Imagine an iPad keyboard that's light, well-built, and also has a hidden touchpad. That's the Fusion Keyboard 2.0, and it's unlike anything I've used before......»»
Untangling the entangled: Quantum study shines fresh light on how neutrinos fuel supernovae
Researchers used quantum simulations to obtain new insights into the nature of neutrinos—the mysterious subatomic particles that abound throughout the universe—and their role in the deaths of massive stars......»»
Torrential rains kill 27 across Central America
Torrential rains across Central America have left at least 27 dead in landslides and flooding over the past week, mainly in El Salvador, but also in Guatemala and Honduras, officials said Friday......»»
A black hole of inexplicable mass: JWST observations reveal a mature quasar at cosmic dawn
The James Webb Space Telescope observed a galaxy in a particularly young stage of the universe. Looking back into the past, it became clear that the light from the galaxy called J1120+0641 took almost as long to reach Earth as the universe has taken.....»»
Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown by scientists at Tokyo Tech to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation......»»
An efficient protein delivery system with spider minor ampullate silk protein nanoparticles
In a study published in the journal MedComm, researchers have developed an efficient protein delivery carrier based on spider silk proteins (spidroins), derived from Araneus ventricosus minor ampullate silk protein (MiSp). The MiSp-based nanoparticle.....»»
Sunlight and plastic: A risky combination for bottled water safety
Plastic water bottles are ubiquitous due to their convenience, yet they harbor potential risks. Sunlight exposure can lead these containers to degrade and emit volatile organic compounds (VOCs), which are potentially detrimental to human health. The.....»»
New photonic chip spawns nested topological frequency comb
Scientists on the hunt for compact and robust sources of multicolored laser light have generated the first topological frequency comb. Their result, which relies on a small silicon nitride chip patterned with hundreds of microscopic rings, appears in.....»»
How calcium reduces macrocracking in sweet cherries
Researchers at the University of Hannover have uncovered new insights into the mode of action of calcium in the reduction of macrocracking in sweet cherry fruit. The findings shed light on the mechanisms underlying this phenomenon, offering significa.....»»
How to fix a red light error on a motherboard
If you've ever built a PC, you now how frustrating that little red light error can be. Here's how to fix it......»»
Turning infrared light visible: New device uses 2D material to up-convert infrared light
The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can't see, has an even lower frequency than red light. Researchers at the Indian Institute of S.....»»
Q&A: New method confines light inside an organic material to form a hybrid quantum state
A team of international scientists led by the University of Ottawa have gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states......»»
A ship found far off Israel"s coast could shed light on the navigation skills of ancient mariners
A company drilling for natural gas off the coast of northern Israel discovered a 3,300-year-old ship and its cargo, one of the oldest known examples of a ship sailing far from land, the Israel Antiquities Authority said Thursday......»»
Electric fields boost graphene"s potential, study shows
Researchers at the National Graphene Institute have made a discovery that could revolutionize energy harnessing and information computing. Their study, published in Nature, reveals how electric field effects can selectively accelerate coupled electro.....»»
Shepherd"s graffiti sheds new light on Acropolis lost temple mystery
