Phys.org / Lead-free alternative discovered for essential electronics component
Ferroelectric materials are used in infrared cameras, medical ultrasounds, computer memory and actuators that turn electric properties into mechanical properties and vice-versa. Most of these essential materials, however, ...
Phys.org / Subtle 'twists' control light in perovskites for improved LEDs, solar cells and quantum technologies
Research has revealed how minute structural modifications in advanced perovskite materials critically influence their light-emission properties.
Phys.org / Ultracold potassium-cesium molecules assembled in absolute ground state
Researchers from Hanns-Christoph Nägerl's group have produced the world's first ultracold KCs molecules in their absolute ground state. Starting by mixing clouds of potassium and cesium atoms cooled almost to absolute zero ...
Medical Xpress / Pause and rewind: How the brain keeps time to control action
Whether speaking or swinging a bat, precise and adaptable timing of movement is essential for everyday behavior. Although we do not have sensory organs like eyes or a nose to sense time, we can keep time and control the timing ...
Medical Xpress / Study shows too much sitting can harm balance and walking, even in young adults
A new study led by Clarkson University Assistant Professor of Physical Therapy Kwadwo Appiah-Kubi shows that too much sitting and too little physical activity can weaken balance and walking ability, even in healthy young ...
Phys.org / Scientists observe metabolic activity of individual lipid droplets in real time
A research team has developed a fluorescent probe that allows scientists to visualize how individual lipid droplets break down inside living cells in real time. The probe changes its fluorescence properties depending on the ...
Medical Xpress / Clogged 'drains' in the brain likely an early-warning sign of Alzheimer's disease
"Drains" in the brain, responsible for clearing toxic waste in the organ, tend to get clogged up in people who show signs of developing Alzheimer's disease, a study by researchers from Nanyang Technological University, Singapore ...
Phys.org / The world's new US$125 billion rainforest trust fund revives a 1990s idea—and shows its limits
A US$125 billion rainforest fund is being hailed as a flagship announcement from the 2025 UN climate summit in Belém, Brazil. The goal is noble: this is essentially a trust fund that will pay countries to keep their tropical ...
Phys.org / Illuminating the messages that cells leave behind: Cells trek along vesicle 'breadcrumbs'
In stunning new time-lapse videos, biological nanoparticles scoot and flit across a starry field of glowing dots. Guided by the invisible chemistry of attraction, these microscopic travelers eventually group together to form ...
Phys.org / A toxin with a useful twist: Diphtheria fragment merges lipid vesicles at neutral pH
Researchers from the SNI network have discovered a novel way to fuse lipid vesicles at neutral pH. By harnessing a fragment of the diphtheria toxin, the team achieved vesicle membrane fusion without the need for pre-treatment ...
Medical Xpress / Researchers urge action as ultra-processed foods dominate diets and threaten public health
Researchers warned Wednesday that rising global consumption of ultra-processed foods (UPFs) poses a major threat to health, calling for countries to subject some products made by huge food companies to marketing restrictions ...
Tech Xplore / Security vulnerability identified in EV charging protocol
Southwest Research Institute identified a security vulnerability in a standard protocol governing communications between electric vehicles (EV) and EV charging equipment. The research prompted the Cybersecurity & Infrastructure ...
