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.....»»
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
The Acropolis of Athens, the rocky hill in the Greek capital that is home to the iconic Parthenon temple, is one of the world's most visited and well-known archaeological sites—but new insights about it are still emerging......»»
Thin and light is back in style, and Apple’s M4 iPad Pro is proof it can be done right
Not too long ago, Apple was on a mission to make all of its devices thinner and lighter. This ambition resulted in iPhones that bent, and MacBook Pros that removed pro ports and had a terrible keyboard. In the past few years, Apple has shifted gea.....»»
Researchers report on effectiveness of violence against women campaigns during sports events
In a paper published in the journal Event Management, researchers have investigated the Gold Coast 2018 Commonwealth Games and its One Million Stars to End Violence (OMSTEV) campaign to see how effective such a campaign was when connected to a major.....»»
Nations realize they need to take risks or lose the race to the moon
The NASA-led Artemis-3 mission will place the first human boots on the surface of the moon since Apollo 17's Gene Cernan and Harrison Schmitt left the lunar surface in December 1972......»»
New method enhances Brillouin optical fiber sensing for infrastructure monitoring
Brillouin scattering is the phenomenon of the inelastic scattering of light by thermally generated acoustic vibrations. Brillouin-based optical fiber sensing can be used to measure temperature and strain distributions by determining how the light sca.....»»
Lung-targeting lipid nanoparticles with CRISPR components successfully treat cystic fibrosis mouse models
A team of medical researchers from the University of Texas Southwestern Medical Center, Case Western Reserve University School of Medicine and ReCode Therapeutics has developed a way to send gene-editing tools to the lungs to repair the faulty gene a.....»»
Extended maternal care is a central factor to animal and human longevity, modeling study suggests
The relationship between mother and child may offer clues to the mystery of why humans live longer lives than expected for their size—and shed new light on what it means to be human......»»
