Popular joint supplement glucosamine linked to faster Alzheimer’s progression
Popular joint supplement glucosamine linked to faster Alzheimer’s progression - Date: - June 10, 2026 - Source: - UF Health - Summary: - A major study suggests glucosamine, a popular supplement for joint pain, could be linked to faster progression from mild cognitive impairment to Alzheimer’s disease. Researchers found a 25% higher likelihood of developing dementia among glucosamine users and uncovered biological clues that may explain why. - Share: A widely used supplement marketed for...

A thalamus–brainstem attractor network drives history-biased decisions
Abstract Natural environments often change gradually, making it adaptive to bias decisions on the basis of the recent past — a phenomenon known as serial dependence1,2,3. Large-scale recordings during behaviour have identified that serial dependence is a common motif for decision-making, with neural representations of past experiences found throughout the brain4,5,6,7,8,9,10,11. However, it remains unclear whether this bias arises from dedicated neural circuits with history-specific...
Efficient and accurate neural-field reconstruction using resistive memory
Abstract Applications such as medical imaging, augmented and virtual reality, and embodied artificial intelligence (AI) depend on the ability to reconstruct complex signals from sparse observations. These applications are characterized by incomplete measurements and limited computational resources. Traditional approaches to digital hardware face the following challenges: explicit signal representations require heavy sampling and storage, data movement across the von Neumann bottleneck...
This strange new phase of matter could transform quantum technology
This strange new phase of matter could transform quantum technology - Date: - May 30, 2026 - Source: - Brown University - Summary: - By stacking custom-designed silver nanoparticles like nanoscale LEGO bricks, scientists stabilized a mysterious crystal phase that had never been observed before. The material not only solves a longstanding puzzle in materials science but also exhibits promising quantum properties at room temperature.
New hydrogen breakthrough turns waste heat into clean fuel
New hydrogen breakthrough turns waste heat into clean fuel A newly developed catalyst could slash the cost and temperature requirements of hydrogen production, opening the door to cleaner, locally generated fuel. - Date: - June 2, 2026 - Source: - University of Birmingham - Summary: - A breakthrough hydrogen-production method could make clean fuel far cheaper and easier to generate.
Scientists discover a quantum effect that could eliminate batteries
Scientists discover a quantum effect that could eliminate batteries - Date: - June 4, 2026 - Source: - Queensland University of Technology - Summary: - Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum effect in an advanced material. The effect can turn alternating electrical signals from the environment directly into the kind of current electronic devices need, without traditional components. As temperature changes, the...
Nvidia Cosmos 3
Physical AI systems must understand the real world before they can act within it. Robots, autonomous vehicles, and smart spaces need to understand what’s happening in their world, predict what’s likely to happen next, and generate actions for specific environments, embodiments, and tasks. NVIDIA Cosmos 3 is a frontier foundation model for physical AI that combines physical reasoning, world generation, and action generation within a single open model.
Scientists discover gut bacteria that may help protect against autism and ADHD
Scientists discover gut bacteria that may help protect against autism and ADHD - Date: - June 2, 2026 - Source: - Cell Press - Summary: - A major study suggests that some of the groundwork for brain development may be shaped before birth through a surprising partnership between a baby’s genes and gut microbes. Researchers found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life, and certain combinations were linked to early...
Whole-genome duplication shaped cell-type evolution in the vertebrate brain
Abstract The complex brains of vertebrates have more cell types than those of their closest relatives. Whole-genome duplications (WGDs) occurred during early vertebrate evolution1, but it is unclear whether the duplicated genes (ohnologues) facilitated cell-type evolution. Here using brain single-cell transcriptomes from five chordates—human2, mouse3, lizard4, lamprey5 and amphioxus—we report that many cell-type families with conserved core transcription factors in vertebrates do not show...
