Developers of the open-source PlayStation 3 emulator RPCS3 identified a workaround for a bug in Nvidia's GPU drivers that was limiting performance. Testing on Red Dead Redemption's Blackwater boat scene showed frame rate gains of 20% on an RTX 3080 setup and 25% on an RTX 5090 setup, while Gran Turismo 5 saw up to 37% faster performance and lower VRAM usage. AMD GPUs were unaffected, suggesting the issue is specific to Nvidia's drivers.
CD Projekt co-CEO Michał Nowakowski said the decision to build The Witcher 4 on Unreal Engine 5 dates back to late 2021, after the studio saw Epic's Matrix Awakens tech demo, rather than being a reaction to Cyberpunk 2077's rocky launch. He clarified that Cyberpunk's problems weren't caused by its engine, and that CD Projekt has since formed a deep partnership with Epic to customize Unreal Engine's core technology for its open-world games.
A new Nature study led by Max Planck Institute astrophysicist Sunmyon Chon simulated conditions in the early universe and found that rapidly forming black holes can generate light signatures matching the mysterious 'little red dots' seen by the James Webb Space Telescope. The team argues these objects quickly develop dense, thick gas disks that produce a strong hydrogen-alpha glow resembling what's observed in these ancient regions of space.
Astronomers using the James Webb Space Telescope had largely concluded that mysterious compact objects called 'little red dots' were supermassive black holes obscured by dust. But two newly analyzed dots studied by teams led by de Graaff and Naidu show a distinctive Balmer break—a spectral signature usually associated with hot stellar surfaces—that standard black hole models don't produce, complicating the picture.
Max Verstappen will compete in a specially staged event at Silverstone, driving one of 101 identical karts sourced from Eastern Europe. The other 100 karts will be piloted by content creators and Red Bull athletes who all start ahead of him, and Verstappen must overtake and eliminate each one across 30 laps to win. The event follows similar but smaller stunts by other F1 drivers like Alex Albon and Oliver Bearman.
HP has begun taking orders for its ZGX Fury AI workstation, a system based on Nvidia's GB300 Grace Blackwell Ultra Desktop Superchip pairing a Blackwell Ultra GPU with a 72-core Grace CPU. The machine offers 748GB of unified, coherent memory and up to 20 petaFLOPS of FP4 compute, and ships alongside a new partnership between HP, Red Hat, and Nvidia to run Red Hat AI Factory software on the hardware.
A developer released ChaosTree, a zero-dependency Java library implementing multiple sorted-tree data structures—AVL, Red-Black, B-Tree, and B+ Tree—with Set and Map APIs modeled on JDK's NavigableSet, NavigableMap, SequencedSet, and SequencedMap interfaces. It also includes specialized bulk-construction methods like buildFromSorted and importFlatMatrix that let developers tune node occupancy directly.
A volunteer has created a public GitHub mirror and continuation of the freedesktop.org SPICE Windows guest agent project after Red Hat stopped maintaining it. The fork keeps building and packaging the Windows service that enables clipboard sharing, resolution matching, and file transfer for VMs, with fixes like a multi-GPU mouse tracking patch for passthrough setups.
Scientists at the University of Utah, including former BYU football player Larry Carr, are researching intranasal transcranial photobiomodulation (itPBM), a red-light therapy aimed at reducing brain inflammation and improving cognition, mood and motor function. A recent study of 26 BYU football players published in the Journal of Neurotrauma found the therapy may help protect neurological health without requiring reduced playing time or contact exposure.
CERN engineers announced at a Winterthur conference that the lab will shift over 2,200 machines from Red Hat Enterprise Linux to Debian. The move stems from RHEL 9 and 10's newer compiler requirements, which drop support for older CPU architectures still used in many of CERN's embedded control systems.
Startup Abliteration.ai now hosts modified, open-weight AI models—including Z.ai's GLM-5.3—with safety refusals removed, letting users query them via browser or API. TechCrunch tested the free web version and got the model to produce password-stealing code and instructions for culturing a dangerous pathogen. The company, founded late last year and incorporated in March, frames this as a service for red-teaming and offensive security testing.
Ornithologist Péter Palatitz has spent 20 years studying the red-footed falcon, a colonial raptor that depends on abandoned rook nests to breed. After rook persecution in the 1980s and '90s destroyed those nesting sites and cut falcon numbers to a quarter of their former size, Palatitz began installing thousands of artificial nest boxes across Hungary in 2006, and the falcon population doubled within ten years. Satellite tracking of 28 birds also revealed they fly nonstop across the Mediterranean and Sahara for five days, covering 6,000 miles to winter in southern Africa.
