Phys.org / Simple treatment strengthens pineapple leaf fibers for sustainable composites
Pineapple leaf fiber has long been valued in parts of Southeast Asia for traditional uses, including basketry in Malaysia and Thailand and textile applications in the Philippines. Its high cellulose content and ready availability ...
Phys.org / Hidden jet from a 'missing-link' black hole lights up the radio sky
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermediate-mass black hole tears apart a star, revealing ...
Phys.org / Measuring iron in motion at Earth-core conditions
It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth's surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several ...
Phys.org / Researchers break a fundamental rule to create a new concept: Heat that can be directed and 'programmed'
Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, ...
Phys.org / Atomic 'domino effect' found to drive phase changes in a two-dimensional crystal
Phase transformations—in which a material changes from one crystal structure to another, thereby acquiring dramatically different properties—are ubiquitous in nature. Understanding the microscopic mechanisms of these transformations ...
Medical Xpress / Is AI ready to take over your prescriptions? Doctors are wary of Utah's automated refill program
A prescription refill program that quietly launched in Utah earlier this year has kicked off a big medical debate: Is artificial intelligence ready to take over tasks that, until now, could only be performed by doctors?
Tech Xplore / Programmable metasurface generates dozens of holograms at once
Over the past few decades, engineers have developed various devices that can create holograms, three-dimensional (3D) or two-dimensional (2D) images produced by precisely controlling the shape and direction of traveling light ...
Phys.org / Euclid discovers the most ancient quasars in the universe
The European Space Agency's Euclid space telescope has discovered 31 of the most ancient quasars ever found. Two of these giant and dazzling galaxy cores, powered by gargantuan black holes, are the earliest quasars yet observed ...
Tech Xplore / How does superconductivity begin? Unveiling the hidden flow of electrons
Superconductivity, a phenomenon in which electricity flows without resistance, is considered the core of quantum computers and next-generation power technologies. However, the exact states electrons undergo before superconductivity ...
Phys.org / El Niño is shaping up for a hot summer—could recycled water be part of the solution?
With El Niño officially declared for summer 2026, Dr. Laura Fernandez and researchers at Macquarie University are testing the use of recycled water to irrigate trees, helping cool Western Sydney.
Phys.org / Huge, specially designed heat pump saves a Norwegian agricultural cooperative millions
There are some magical limits to how much energy we can get out of a heat pump. This story is about pushing the technical limits. It is about getting more energy out than you put in. And it's about how SINTEF—one of Europe's ...
Phys.org / Crystal-design principle reveals how competing molecular forces control structure, color and phase transitions
Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular ...
