Structured light beams with controllable polarization along arbitrary trajectories
A structured light refers to a light field which is "customized" in both space and time, characterized by its unique distribution of amplitude, phase, and polarization state in both space and time......»»
Intel-powered computers affected by serious firmware flaw (CVE-2024-0762)
A vulnerability (CVE-2024-0762) in the Phoenix SecureCore UEFI, which runs on various Intel processors, could be exploited locally to escalate privileges and run arbitrary code within the firmware during runtime. “This type of low-level exploit.....»»
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.....»»
Researchers reveal effects of climate change on above- and belowground biomass distribution on Tibetan plateau
Global warming has significantly altered plant growth patterns on the Tibetan Plateau (TP) over the past three decades. Plants adjust their growth trajectories in response to climate change, prioritizing leaf and stem growth or root extension to bett.....»»
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......»»
Improving crops with laser beams and 3D printing
A demonstration of how new technologies can be used in 21st century crop breeding comes from just published research that combines laser scanning and 3D printing to create a detailed 3D model of a sugar beet plant......»»
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.....»»
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.....»»
Polarization and risk perception could play important roles in climate-policy outcomes
Times of crises often call for strong and rapid action, but in polarized societies, strong top-down policies can backfire......»»
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......»»
Light-Based Chips Could Help Slake AI"s Ever-Growing Thirst for Energy
Optical neural networks, which use photons instead of electrons, have advantages over traditional systems. They also face major obstacles......»»
Stellantis cuts costs rather than turn defensive as Chinese threat grows
CEO Carlos Tavares said Stellantis would stick to its "asset light" strategy in China, mainly focused on exporting to the country rather than manufacturing there. .....»»
Novel photocatalyst enables efficient ester reduction with blue light
The sweet smell of strawberries and other fruits is thanks to a chemical compound called ester, which is also found in many fats and polyesters. The ubiquitous compound can be broken down to produce desirable alcohols and other chemicals for use acro.....»»
Strong coupling and catenary field enhancement in the hybrid plasmonic metamaterial cavity and TMDC monolayers
Researchers in the field of nanophotonics have spent significant time in recent years investigating fascinating concepts known as polaritons and/or plexcitons. These ideas revolve around the strong coupling of light photons and/or plasmons to exciton.....»»
