Physicists have developed a lens with 'magic' properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.

Despite advances in machine vision, processing visual data requires substantial computing resources and energy, limiting deployment in edge devices. Now, researchers from Japan have developed a self-powered artificial synapse that distinguishes colors with high resolution across the visible spectrum, approaching human eye capabilities. The device, which integrates dye-sensitized solar cells, generates its electricity and can perform complex logic operations without additional circuitry, paving the way for capable computer vision systems integrated in everyday devices.

Researchers have synthesized a new compound called infuzide that shows activity against resistant strains of pathogens.

Researchers have recreated the world's oldest synthetic pigment, called Egyptian blue, which was used in ancient Egypt about 5,000 years ago.

Researchers have discovered that the mixing of small particles between two solid electrolytes can generate an effect called a 'space charge layer,' an accumulation of electric charge at the interface between the two materials. The finding could aid the development of batteries with solid electrolytes, called solid-state batteries, for applications including mobile devices and electric vehicles.

Researchers have engineered a laser device smaller than a penny that they say could power everything from the LiDAR systems used in self-driving vehicles to gravitational wave detection, one of the most delicate experiments in existence to observe and understand our universe.

Scientists have reported use of antibacterial coatings made from resilin-mimetic proteins to fully block bacteria from attaching to a surface. A protein that gives fleas their bounce has been used to boot out bacteria cells, with lab results demonstrating the material's potential for preventing medical implant infection.

New research shows that the presence of solar panels in Colorado's grasslands may reduce water stress, improve soil moisture levels and -- particularly during dry years -- increase plant growth by about 20% or more compared to open fields.

Students recently unveiled their invention of a robotic actuator -- the 'muscle' that converts energy into a robot's physical movement -- that has the ability to detect punctures or pressure, heal the injury and repair its damage-detecting 'skin.'

Researchers proposed a novel strategy for using a magnetic field to boost the efficiency of single-atom catalysts -- thus speeding up helpful reactions used for ammonia production and wastewater treatment.

A new method for predicting underwater landslides may improve the resilience of offshore facilities.

Researchers present new experimental and theoretical results for the bound electron g-factor in lithium-like tin which has a much higher nuclear charge than any previous measurement. The experimental accuracy reached a level of 0.5 parts per billion. Using an enhanced interelectronic QED method, the theoretical prediction for the g-factor reached a precision of 6 parts per billion.

Researchers determined how much outdoor particulate pollution affects indoor air quality. Their study concluded pollution from inversion and dust events is kept out of buildings, but wildfire smoke can sneak inside if efficient 'air-side economizers' are in use.

Scientists have developed a powerful new tool for finding the next generation of materials needed for large-scale, fault-tolerant quantum computing. The significant breakthrough means that, for the first time, researchers have found a way to determine once and for all whether a material can effectively be used in certain quantum computing microchips.

As the world shifts toward sustainable energy sources, 'green hydrogen' - hydrogen produced without emitting carbon - has emerged as a leading candidate for clean power. Scientists have now developed a new iron-based catalyst that more than doubles the conversion efficiency of thermochemical green hydrogen production.

SAVANA uses a machine learning algorithm to identify cancer-specific structural variations and copy number aberrations in long-read DNA sequencing data. The complex structure of cancer genomes means that standard analysis tools give false-positive results, leading to erroneous clinical interpretations of tumour biology. SAVANA significantly reduces such errors. SAVANA offers rapid and reliable genomic analysis to better analyse clinical samples, thereby informing cancer diagnosis and therapeutic interventions.

Lightweight, powerful lithium-ion batteries are crucial for the transition to electric vehicles, and global demand for lithium is set to grow rapidly over the next 25 years. A new analysis looks at how new mining operations and battery recycling could meet that demand. Recycling could play a big role in easing supply constraints, the researchers found.

In a major advancement for sustainable construction, scientists have created a cement-free soil solidifier from industrial waste. By combining Siding Cut Powder and activated by Earth Silica, an alkaline stimulant from recycled glass, scientists produced a high-performance material that meets compressive strength standards exceeding the 160 kN/m construction-grade threshold and eliminates arsenic leaching through calcium hydroxide stabilization. The technology reduces landfill volumes and carbon emissions, offering a circular solution for infrastructure development worldwide.

Current regulations for nanomedicines overlook the effects of the different forms of the same element, such as ions, nanoparticles, and aggregates. In a recent study, researchers developed a new analytical method combining an asymmetric flow field-flow fractionation system and mass spectrometry to separately quantify these forms. This technique allows for better quality control and safety evaluation of metal-based nanomedicines, promoting their development and clinical use, with applications also extending to food, cosmetics, and the environment.

Researchers have demonstrated a new technique that uses lasers to create ceramics that can withstand ultra-high temperatures, with applications ranging from nuclear power technologies to spacecraft and jet exhaust systems. The technique can be used to create ceramic coatings, tiles or complex three-dimensional structures, which allows for increased versatility when engineering new devices and technologies.
