An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized laser pulse and a circularly polarized probe laser to create the spin currents.
An international team of researchers has found a surprisingly simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. Their work was published in Physical Review Letters on August 30.
In the realm of lighting and temperature measurement, advancements in material science are paving the way for significant improvements in technology and safety. Traditional methods, which combine yellow phosphors with blue chips in LEDs, have limitations such as inadequate red light components that affect color rendering and potential hazards from blue light exposure.
Something to look forward to: Improved ray tracing performance is one of the key benefits of Sony’s newly unveiled PlayStation 5 Pro console. Prior to its debut, rumors had long suggested that the mid-generation refresh would incorporate ray tracing technology based on AMD’s upcoming RDNA 4 GPU architecture. Recent comments from PlayStation designer Mark Cerny have all but confirmed these theories.
In a detailed interview with CNET following the reveal of Sony’s PlayStation 5 Pro console, designer Mark Cerny confirmed rumors that the device’s ray tracing capabilities are built on an architecture not yet available in AMD’s PC graphics cards. While Cerny didn’t explicitly name RDNA 4, no other viable candidates are known.

If you’ve ever opened a box from IKEA and wished the pieces inside could somehow spontaneously merge to form a table or chair, then a simple virus could have a thing or two to teach you. Self-assembly of complex molecules is essential for a wide array of biological structures, including proteins, cell membranes, or even entire viruses. Supramolecular chemistry is a field of study that attempts to build large molecules out of a discrete number of…
Chinese astronomers have uncovered a low-mass black hole that challenges long-held astrophysical theories. This black hole, part of a binary system known as G3425, has a mass of about 3.6 solar masses, placing it in the elusive mass-gap where black holes were previously thought to be absent. The discovery was made using a combination of radial velo…
The atom’s nucleus could safely store quantum data, with controlled wobbling making it possible:
According to the researchers, the spin state or direction of the spin of a nucleus can be used to hold quantum information.
“This magnetism, the “spin” in quantum language, can be seen as a sort of compass needle that can point in various directions. The orientation of the spin at a given time constitutes a piece of quantum information,” the study authors said.

Researchers went ‘bioprospecting’ in marine microbes, looking for those that can perform helpful functions like eating plastic or generating antibiotics. | Earth And The Environment.
Summary: A new study using artificial intelligence has provided novel insights into how the brain predicts future events and processes information. Researchers discovered that the brain’s spontaneous activity, even without external stimuli, plays a critical role in how we think and feel.
By analyzing local field potentials (LFPs), they uncovered how the brain remains active in anticipating possible scenarios, even in a resting state. These findings could lead to better diagnostic tools and treatments for neurological diseases.
