Why Daily Statins May Lower Your Patient’s Glaucoma Risk
Lower glaucoma rates among statin users offer an exciting glimpse into how treating systemic health could help preserve sight.
Scientists discover hidden brain changes linked to common sleep disorders
Scientists have discovered that sleep disorders are associated with structural changes in brain regions that control attention, decision-making, and emotions, potentially explaining why disrupted sleep can affect everyday thinking and behavior. The findings, drawn from 57 brain imaging studies, reveal both shared and disorder-specific patterns that could lead to more targeted treatments.
Northwestern engineers create artificial neurons that communicate with living cells
Northwestern University engineers printed artificial neurons that don’t just imitate the brain — they talk to it.
In a new study, the Northwestern team developed flexible, low-cost devices that generate electrical signals realistic enough to activate living brain cells. When tested on slices of tissue from mouse brains, the artificial neurons successfully triggered responses from real neurons, demonstrating a new level of biocompatibility.
The work marks a step toward electronics that can communicate directly with the nervous system, with potential applications in brain-machine interfaces and neuroprosthetics, including implants for hearing, vision and movement.
New study indicates key health indicator that increases risk of Alzheimer’s by a third
One alarming new study has identified a link between the development of Alzheimer’s disease and one key health indicator that millions suffer from worldwide, indicating that it increases the risk by around a third.
Alzheimer’s disease is one of the most challenging health conditions that people run the risk of dealing with in their later years, as it deteriorates your brain’s ability to think, makes remembering things harder, and even affects your behavior.
Some studies have discovered unorthodox ways of reducing the risk of developing this condition, including engaging in a rather gross habit or reaching a certain step count every single day, but it remains a challenge for medical experts across the globe to fight every year.
This Robotic Hand Walks on Its Fingers Like Thing From The Addams Family, And It’s Creepy as Heck
Watching a hand walk away on its fingers brings to mind Thing from The Addams Family. Heidi Klum brought a gruesome version to life this Halloween with her giant severed-hand costume.
In a Swiss robotics lab, a mechanical hand is taking its own steps toward something more useful.
Researchers at ETH Zurich taught it to walk on its fingertips, get upright after a fall, and press keyboard keys while balancing on its other fingers.
¿El tiempo es una ilusión? Este experimento con un “miniuniverso” profundiza en ello
Is time an illusion? This experiment with a “mini-universe” delves deeper into the question.
Un universo en miniatura permitió probar la idea radical de que el tiempo podría surgir de los cambios entre partículas y no de un reloj externo.
Astronomers may have discovered the first moon beyond our Solar System
Astronomers have uncovered evidence of a bizarre, potentially historic discovery: the first moon ever detected beyond our Solar System. Unlike familiar moons, this mysterious object is at least as massive as Jupiter and orbits a browndwarf, which itself circles a star. The unusual arrangement challenges traditional definitions of planets and moons, leaving scientists unsure what to call it.
Astronomers may have found the first moon beyond our Solar System, but the mysterious object is unlike any moon we know. Observations from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have uncovered evidence of an enormous moon-like body in the CD-35 2,722 star system. Rather than orbiting a planet, this unusual object circles a brown dwarf, a celestial body more massive than a planet but not massive enough to become a star.
If confirmed, the discovery could mark the first detection of a natural satellite outside our Solar System, potentially changing how astronomers define moons and planets.
Sea cucumber–inspired gel could help heal damaged tissue in humans
Inspired by the ability of sea cucumbers to change the stiffness of their bodies, University of Waterloo researchers have developed a gel that could one day help repair damaged tendons and other soft tissues without leaving permanent material behind.
A paper on the study, “Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft-Tissue Interfaces,” was recently published in the journal Advanced Functional Materials.
The water-rich material, known as a hydrogel, acts as a temporary support structure that allows new tissue to grow as the material gradually breaks down. Like the sea cucumbers that inspired it, the gel can be made softer or stiffer, potentially allowing it to support the healing of different tissues throughout the body.
Robots rely heavily on vision to understand their surroundings and plan movements
But when performing delicate tasks that involve physical contact, vision alone may not be fast enough. By the time a robot processes a new image and recalculates its next move, the object may have shifted, a grip may have slipped, or the contact conditions may already have changed. https://arxiv.org/abs/2610.
A new architecture called T-WLA (Tactile World-Language-Action) addresses this problem by combining visual understanding with real-time tactile feedback.
The central idea is to let vision plan the movement while touch makes rapid adjustments.
The system first processes camera images, task instructions, and previous interaction history to create a shared visual memory. This memory guides the robot’s initial actions and is also retained for a separate tactile component. When the robot’s fingers encounter unexpected changes, the tactile component uses this stored information, together with incoming touch signals, to adjust the remaining movements without having to run the slower visual processing system all over again.
The researchers also train the architecture to anticipate what future images and pressure patterns might look like during physical interactions. Although these predictions are used only during training, they help the model learn the dynamics of contact and how movements should respond to changing physical conditions.
The researchers evaluated T-WLA using two tactile datasets, EgoTouch and Tachin, as well as four real-world dexterous manipulation tasks involving physical robots.
The results are promising: T-WLA reduced finger-joint prediction errors by 30% compared with the strongest reported baseline and achieved an average success rate of approximately 50% across the real-world manipulation tasks.
The broader significance is that effective robotic manipulation requires more than recognizing objects and planning movements. Robots must also respond to the physical world as it unfolds.
