Superconductors, 3D Disorder, Fractals…
Fractals are a never-ending pattern that you can zoom in on, and the image doesn’t change. Fractals can occur in two dimensions, like frost on a window, or in three dimensions, like the limbs of a tree. A recent discovery from Purdue University researchers has established that superconducting images, seen above in red and blue,Continue reading “Superconductors, 3D Disorder, Fractals…”
Removing the Spookiness…

Credit: Science Photo Library/Alamy Stock Photo Topics: Modern Physics, Particle Physics, Quantum Mechanics, Theoretical Physics Quantum entanglement is a complex phenomenon in physics that is usually poorly described as an invisible link between distant quantum objects that allows one to instantly affect the other. Albert Einstein famously dismissedContinue reading “Removing the Spookiness…”
Rate of Expansion…
A University of Minnesota Twin Cities-led team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe’s age and help physicists and astronomers better understand the cosmos.

Rather, this pernicious white-gloved war was prosecuted byContinue reading “The Illusion of Perfection…”
Electrical Wound Care…
New research from Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, shows that wounds on cultured skin cells heal three times faster when stimulated with electric current. The project was recently granted more funding so the research can get one step closer to the market and the benefit of patients. Credit: ScienceContinue reading “Electrical Wound Care…”

TEG…
The new self-powered thermoelectric generator device uses an ultra-broadband solar absorber (UBSA) to capture sunlight, which heats the generator. Simultaneously, another component called a planar radiative cooling emitter (RCE) cools part of the device by releasing heat. Credit: Haoyuan Cai, Jimei University.

Graphical abstract. Credit: Nanomaterials (2023). DOI: 10.3390/nano13081404 Topics: Biology, Environment, Nanomaterials, Nanotechnology Among the biggest environmental problems of our time, micro- and nanoplastic particles (MNPs) can enter the body in various ways, including through food. And now, for the first time, research conducted at MedUni Vienna has shown how these minute particles manage to breach the blood-brainContinue reading “Mice, Men, and Nanoparticles…”

Credit: CC0 Public Domain Topics: Applied Physics, Chemistry, Materials Science, Metamaterials, Quantum Mechanics The behavior of so-called “strange metals” has long puzzled scientists—but a group of researchers at the University of Toronto may be one step closer to understanding these materials. Electrons are discrete, subatomic particles that flow through wires like molecules of water flowingContinue reading “Strange Metals II…”
