The upcoming facility comes as part of a multi-building development earmarked for the Central Texas community.

British-built Hawk-Eye software goes dark during Wimbledon match
Wimbledon’s new automated line-calling system glitched during a tennis match Sunday, just days after it replaced the tournament’s human line judges for the first time.
The system, called Hawk-Eye, uses a network of cameras equipped with computer vision to track tennis balls in real-time. If the ball lands out, a pre-recorded voice loudly says, “Out.” If the ball is in, there’s no call and play continues.
However, the software temporarily went dark during a women’s singles match between Brit Sonay Kartal and Russian Anastasia Pavlyuchenkova on Centre Court.
Mixture-of-Recursions: Learning Dynamic Recursive Depths for Adaptive Token-Level Computation
View recent discussion. Abstract: Scaling language models unlocks impressive capabilities, but the accompanying computational and memory demands make both training and deployment expensive. Existing efficiency efforts typically target either parameter sharing or adaptive computation, leaving open the question of how to attain both simultaneously. We introduce Mixture-of-Recursions (MoR), a unified framework that combines the two axes of efficiency inside a single Recursive Transformer. MoR reuses a shared stack of layers across recursion steps to achieve parameter efficiency, while lightweight routers enable adaptive token-level thinking by dynamically assigning different recursion depths to individual tokens.
Next-gen rod LEDs could transform smartphones and TVs with ultra-bright and color-rich displays
Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world’s brightest and most energy efficient quantum rod LEDs (QRLEDs). These next-generation QRLEDs feature optimized deep green emission at the top of the color triangle, enabling displays with unprecedented color purity and a maximized color gamut.
Boasting a longer lifespan and triple the brightness of previous models, these cutting-edge light sources deliver energy-efficient, ultra-vivid visuals for smartphones, televisions, and AR/VR devices while further enhancing color performance.
Light-emitting diodes (LEDs) have been widely used in electronic products for decades. Recent advancements in quantum materials have given rise to quantum dot LEDs (QLEDs) and QRLEDs. Both offer narrow emission bandwidths and high color purity, surpassing traditional LEDs. Among these, QRLEDs excel with higher light outcoupling efficiency.
Scientists detect new ‘quantum echo’ in superconducting materials
Scientists at the U. S. Department of Energy Ames National Laboratory and Iowa State University have discovered an unexpected “quantum echo” in a superconducting material. This discovery provides insight into quantum behaviors that could be used for next-generation quantum sensing and computing technologies.
Superconductors are materials that carry electricity without resistance. Within these superconductors are collective vibrations known as “Higgs modes.” A Higgs mode is a quantum phenomenon that occurs when its electron potential fluctuates in a similar way to a Higgs boson. They appear when a material is undergoing a superconducting phase transition.
Observing these vibrations has been a long-time challenge for scientists because they exist for a very short time. They also have complex interactions with quasiparticles, which are electron-like excitations that emerge from the breakdown of superconductivity.
New research connects quantum computing power to the security of cryptographic systems
Experts say quantum computing is the future of computers. Unlike conventional computers, quantum computers leverage the properties of quantum physics such as superposition and interference, theoretically outperforming current equipment to an exponential degree.
When a quantum computer is able to solve a problem unfeasible for current technologies, this is called the “quantum advantage.” However, this edge is not guaranteed for all calculations, raising fundamental questions regarding the conditions under which such an advantage exists. While previous studies have proposed various sufficient conditions for quantum advantage, the necessity of these conditions has remained unclear.
Motivated by this uncertainty, a team of researchers at Kyoto University has endeavored to understand the necessary and sufficient conditions for quantum advantage, using an approach combining techniques from quantum computing and cryptography, the science of coding information securely.
Terabytes of data in a tiny crystal
From punch card-operated looms in the 1800s to modern cellphones, if an object has “on” and “off” states, it can be used to store information.
In a laptop computer, the ones and zeroes that make up the binary language are actually transistors either running at low or high voltage. On a compact disc, the one is a spot where a tiny indented “pit” turns to a flat “land” or vice versa, while a zero represents no change.
Historically, the size of the object cycling through those states has put a limit on the size of the storage device. But now, researchers from the University of Chicago Pritzker School of Molecular Engineering have explored a technique to make the metaphorical ones and zeroes out of crystal defects, each the size of an individual atom, for classical computer memory applications.
UChicago researchers created a ‘quantum-inspired’ revolution in microelectronics, storing classical computer memory in crystal gaps where atoms should be.

The first-of-its-kind silicon chip combines both the quantum light-generating components (photonics) with classical electronic control circuits — all packed into an area measuring just one millimeter by one millimeter.
New gene tool leads to better treatments for complex diseases
Genetic changes can signal evidence of disease, but pinpointing which genes and what’s changed can be difficult.
But in a study of traits that offer clues to a person’s cardiovascular health —such as lipid and glucose levels and inflammation—a team of researchers at Case Western Reserve University devised a computational method and tool to improve how genes and genetic changes that cause diseases are identified.
Their new approach could allow doctors to detect and treat so-called cardiometabolic diseases earlier in their development. Their findings were recently published in the journal Nature Communications.
A chaos-modulated metasurface for physical-layer secure communications
With so many people using devices that can be connected to the internet, reliably securing wireless communications and protecting the data they are exchanging is of growing importance. While computer scientists have devised increasingly advanced security measures over the past decades, the most effective techniques rely on complex algorithms and intensive computations, which can consume a lot of energy.
Researchers at Peking University, Southeast University, University of Sannio and other institutes recently introduced a new approach for securing communications both effectively and energy-efficiently, which relies on a reconfigurable metasurface with properties that are modulated by chaotic patterns.
This approach, outlined in a paper published in Nature Communications, is based on an idea conceived by the senior authors Vincenzo Galdi, Lianlin Li and Tie Jun Cui, who oversaw the project. The idea was then realized at Peking University and Southeast University by junior authors JiaWen Xu Menglin Wei and Lei Zhang.
