No, AI isn’t conscious
Research from the University of Bradford and RIT shows that AI systems aren’t conscious, even when they appear to be. Tests adapted from human consciousness research revealed that AI can produce “conscious‑like” signals even when degraded, highlighting why complexity doesn’t equal awareness and why claims of conscious AI are misleading.
Ultra-cold quantum sensors cut X-ray uncertainty, improving nuclear material assessments
To monitor the amount and type of nuclear material at power plants and weapons facilities, scientists look for a special signal—the unique pattern of gamma rays emitted by specific radioactive elements. However, some of these elements also emit X-rays in the same energy range as the gamma-ray emissions, masking the signal and making nuclear stockpiles harder to assess.
Now, researchers at the National Institute of Standards and Technology (NIST) have measured the confounding X-ray emissions from plutonium, uranium and neptunium (a nuclear decay product of uranium) with unprecedented accuracy. This achievement allows scientists to filter out the X-ray background noise so they can more precisely evaluate the accumulation of nuclear materials.
“Our measurements support international nuclear safeguards by enabling more precise accounting of material in nuclear facilities,” said Jonathan Dean, a physicist at NIST and the University of Colorado Boulder.
HiPR Makes Path Tracing More Responsive by Rendering What Matters
Path tracing can produce remarkably realistic lighting, reflections, and shadows, but that visual quality comes with a fundamental responsiveness problem. When an artist moves an object, changes a material, or adjusts a light, the renderer may effectively restart the entire image—even when only certain areas are meaningfully affected. For creators working in look development, virtual production, level design, or architectural visualization, that delay can interrupt the iterative process.
Hierarchical Progressive Rendering, or HiPR, approaches the problem as one of scheduling. Developed by University of Utah researcher Rafael Padilla alongside Andrew Tate, Dhruv Ram, and Cem Yuksel, the technique identifies where an edit is directly visible and follows its influence through reflections, shadows, indirect illumination, and other light-transport paths. It then updates the most important image regions first while the remaining pixels progressively catch up, ultimately producing the same unbiased path-traced result.
How ABCD Trains Large Gaussian Splat Scenes With Constant VRAM
Researcher Ka Heng Shiu explains how Alpha-Composited Block Coordinate Descent (ABCD) divides large radiance fields into manageable partitions while preserving full-scene context during training.
Practical Wellness Strategies for Neurodivergent Individuals
Crafting a health roadmap can help you move toward a more balanced and fulfilling life. For neuro-divergent individuals, taking intentional steps to address harmful habits and prioritize wellness can make a significant difference in daily living. By focusing on small, achievable strategies, you can establish a plan that works for you and supports your unique needs. Here are some tips from Different Brains to help with creating habits that encourage well-being and lead to a healthier, happier lifestyle.
The people you surround yourself with can shape your mindset and choices. Seek out relationships with individuals who offer positivity and encouragement. This can include friends, family members, or support groups that understand and appreciate your experiences. A strong network creates an environment where you feel safe to grow and take steps toward your goals. By maintaining these connections, you’ll find the motivation and understanding you need to succeed.
As a neuro-divergent individual, focusing on nutrition can have a substantial impact on your overall health and vitality. It’s essential to include a variety of nutrient-rich foods, such as fruits, vegetables, and lean proteins, which can stabilize mood and energy levels throughout the day. The best greens supplements, free from artificial additives and sourced organically, are especially beneficial as they ensure you receive vital nutrients that support cognitive function and emotional well-being. Incorporating these powdered supplements into smoothies not only makes consumption enjoyable but also aids in maintaining a balanced diet that suits your sensory preferences.
