Astronomers have found the home address for the universe’s ‘missing’ matter
A new landmark study has pinpointed the location of the universe’s “missing” matter, and detected the most distant fast radio burst (FRB) on record. Using FRBs as a guide, astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) and Caltech have shown that more than three-quarters of the universe’s ordinary matter has been hiding in the thin gas between galaxies, marking a major step forward in understanding how matter interacts and behaves in the universe.
They’ve used the new data to make the first detailed measurement of ordinary matter distribution across the cosmic web. The research is published in the journal Nature Astronomy.
For decades, scientists have known that at least half of the universe’s ordinary, or baryonic matter —composed primarily of protons—was unaccounted for. Previously, astronomers have used techniques including X-ray emission and ultraviolet observations of distant quasars to find hints of vast amounts of this missing mass in the form of very thin, warm gas in between galaxies. Because that matter exists as hot, low-density gas, it was largely invisible to most telescopes, leaving scientists to estimate but not confirm its amount or location.
New theory proposes time has three dimensions, with space as a secondary effect
Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist.
The theory also argues that time comes in three dimensions rather than just the single one we experience as continual forward progression. Space emerges as a secondary manifestation.
“These three time dimensions are the primary fabric of everything, like the canvas of a painting,” said associate research professor Gunther Kletetschka at the UAF Geophysical Institute. “Space still exists with its three dimensions, but it’s more like the paint on the canvas rather than the canvas itself.”

Information geometry has emerged from the study of the invariant structure in families of probability distributions. This invariance uniquely determines a second-order symmetric tensor g and third-order symmetric tensor T in a manifold of probability distributions. A pair of these tensors (g, T) defines a Riemannian metric and a pair of affine connections which together preserve the metric. Information geometry involves studying a Riemannian manifold having a pair of dual affine connections. Such a structure also arises from an asymmetric divergence function and affine differential geometry. A dually flat Riemannian manifold is particularly useful for various applications, because a generalized Pythagorean theorem and projection theorem hold. The Wasserstein distance gives another important geometry on probability distributions, which is non-invariant but responsible for the metric properties of a sample space. I attempt to construct information geometry of the entropy-regularized Wasserstein distance.
Advanced algorithm to study catalysts on material surfaces could lead to better batteries
A new algorithm opens the door for using artificial intelligence and machine learning to study the interactions that happen on the surface of materials.
Scientists and engineers study the atomic interactions that happen on the surface of materials to develop more energy efficient batteries, capacitors, and other devices. But accurately simulating these fundamental interactions requires immense computing power to fully capture the geometrical and chemical intricacies involved, and current methods are just scratching the surface.
“Currently it’s prohibitive and there’s no supercomputer in the world that can do an analysis like that,” says Siddharth Deshpande, an assistant professor in the University of Rochester’s Department of Chemical Engineering. “We need clever ways to manage that large data set, use intuition to understand the most important interactions on the surface, and apply data-driven methods to reduce the sample space.”
Three-mode smart window cut indoor temperature by 27°C and eliminate urban glare
In the building sector, which accounts for approximately 40% of global energy consumption, heat ingress through windows has been identified as a primary cause of wasted heating and cooling energy.
A KAIST research team has successfully developed a ‘pedestrian-friendly smart window’ technology capable of not only reducing heating and cooling energy in urban buildings but also resolving the persistent issue of ‘light pollution’ in urban living.
Professor Hong Chul Moon’s research team at KAIST’s Department of Chemical and Biomolecular Engineering have developed a ‘smart window technology’ that allows users to control the light and heat entering through windows according to their intent, and effectively neutralize glare from external sources.
Developer Proves His Game Engine Runs Faster Than Unity on Web
Gabriel Dechichi, a developer you might know from his challenge of making an Unreal Engine game in 4 weeks, is building his own C engine, and he’s ready to prove it’s better than Unity, at least in web space.
Dechichi made a demo where you can add hundreds of running mannequins and see how your system reacts to the stress. The creator claims his engine is “10x faster, 10x lighter, 10x better” than other software, and 14 times quicker than Unity in particular.
It’s obvious from first glance even at 100 characters that Dechichi’s engine runs smoother, but I tested it on my MacBook Pro, and while the C engine works with 1,000 units at 250 ms and 1 FPS, Unity took forever to load so many characters at 1,300 ms and 1 FPS. So, I guess, Dechichi is right, and we’ll see a nice addition to the gamedev world soon.
