Microsoft has confirmed that Windows 11 is getting a new modern Run dialog with dark mode support and faster performance in a new preview build 26300.8346.
The Run dialog has been around since the Windows 95 era, and it is one of those small Windows features that many power users still rely on every day.
You just need to press Win + R, type a command, open a file path, launch a tool, or quickly jump to a location without opening File Explorer first.
The concept of spacetime, first described in Einstein’s theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum in which physical events occur, which merges three-dimensional (3D) space, with one-dimensional (1D) time.
This 4D continuum is known to continuously evolve following complex and intricate patterns that are governed by Einstein’s field equations; mathematical equations that describe how matter and energy shape spacetime. While various past theoretical studies explored the evolution of spacetime, identifying patterns that persist during its evolution has proved challenging so far.
Researchers at Adolfo Ibáñez University in Chile and Columbia University set out to explore the evolution of spacetime using ideas rooted in nonlinear electrodynamics, an area of physics that studies the behavior of electric and magnetic fields in complex materials.

As global demand for lithium-ion batteries continues to surge, a team of Rice University researchers has developed a faster, more energy-efficient way to recover critical minerals from spent batteries, potentially easing supply chain pressures and reducing environmental harm.
In a new study published in Small, researchers from Rice’s Department of Materials Science and Nanoengineering introduce a class of water-based solutions that can extract valuable metals from battery waste in minutes rather than hours. The work centers on aqueous solutions of amino chlorides, which mimic the performance of commonly studied green solvents like deep eutectics, while avoiding their key limitations.
“Traditional recycling methods often rely on harsh acids or slow, energy-intensive processes,” said the study’s first author, Simon M. King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute. “What we’ve shown is that you can achieve rapid, high-efficiency metal recovery using a much simpler, water-based system.”
Researchers have demonstrated the first “all-in-one” cocatalyst for photocatalytic overall water splitting, a breakthrough that could simplify the production of clean hydrogen fuel. The discovery marks an important step toward practical technologies that use sunlight and water to generate hydrogen, a key energy carrier expected to play a major role in building a decarbonized and sustainable society.
The findings are published in the journal Nature Chemistry.
Hydrogen is widely regarded as a promising clean energy source because it produces only water when used as fuel. Among the various methods for producing hydrogen, photocatalytic overall water splitting —using sunlight to split water into hydrogen and oxygen—has attracted increasing attention as an environmentally friendly and sustainable approach.
Researchers have uncovered new insights into the early development of baby stars. As published in The Astrophysical Journal Letters, a research team from Kyushu University and Kagawa University reports that during the early growth period of a baby star, the protostellar disk—the dense disk of gas and dust that surrounds the star—expels magnetic flux and forms a giant warm ring of gas about 1,000 au (astronomical units) in size. The research team explains that these “sneezes” of matter and magnetic energy help the baby star release excess energy, leading to proper star formation.
One of the many mysteries that the universe holds is how stars like our sun are born. Stars are born in areas of the cosmos called stellar nurseries, where gas and dust coalesce to form early stars called protostars. The best way to understand star formation is to observe these stellar nurseries. However, this can be difficult due to the aforementioned gas and dust obscuring the baby star.
“Thankfully, one of the most promising ways to get a clear view of protostars is to use the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile,” explains Professor Masahiro N. Machida of Kyushu University’s Faculty of Science, who led the study. “This radio telescope lets us see the different materials that make up stellar nurseries.”
A new method developed at LMU overcomes fundamental resolution limits and may provide insights into high-temperature superconductivity. Physicist Dr. Sebastian Paeckel has developed a method that can be used to calculate spectral functions of complex quantum systems much more precisely than was possible previously. His approach reconstructs precise energy spectra without requiring lengthy calculations.
This reveals previously hidden details, as Paeckel reports in the journal Physical Review Letters. He conducts research at the Faculty of Physics at LMU and at the Munich Center for Quantum Science and Technology (MCQST).
