The human sense of touch involves a complex network of specialized neurons detecting various stimuli across the body. Harvard neuroscientist David Ginty has mapped out 18+ distinct types of touch neurons, revealing how different nerve endings respond to sensations like pressure, vibration, temperature, and hair movement in both skin and internal organs.
A new prosthetic hand from Psyonic offers 32 grip patterns and touch-sensing capabilities, allowing users to feel objects through vibrations. The Ability Hand features rapid 200-millisecond closing speed, weighs only 490 grams,...
Kurt Vonnegut's novel Slaughterhouse-Five explores the idea of experiencing time non-linearly. The concept suggests human consciousness could move through time independently of the brain, which provides sensory input and memories...
Research into ice and snow properties is advancing, potentially leading to better ice-repellent materials and avalanche prediction methods, which could enhance safety and engineering practices in cold regions.
A breakthrough in battery technology could double the lifespan of lithium-ion batteries. Scientists from China and the U.S. have achieved 100% voltage recovery in aging batteries using materials with zero thermal expansion...
Eleven companies have agreed to create a liquid hydrogen corridor from Oman to Europe, building export facilities, negotiating contracts, and developing logistics to deliver renewable hydrogen to industrial hubs in the...

NASA's Perseverance rover has found evidence of multiple mineral-forming events beneath Mars' surface, providing new insights into the planet's water history and potential habitability. Researchers used a novel X-ray technique to...
Engineers have developed a living building material made from fungal mycelium and bacteria cells that can self-repair and survive for weeks. This bio-based composite, created at low temperatures, could reduce the construction...
Analysis of a meteorite suggests Earth's early composition contained abundant hydrogen, challenging the theory that water came from asteroid impacts and indicating it likely formed naturally from the planet's existing elements.
Dutch engineers have repurposed a decommissioned wind turbine blade to create an innovative 3D-printed modular bridge. The 39-foot structure in Almere can support loads up to 5 tons and incorporates recycled materials throughout....
Researchers at Brown University found that injecting gold nanoparticles into mice's eyes and stimulating them with lasers could activate the visual system, suggesting a potential new treatment for retinal disorders like macular...
The new method transforms gunshot residue into luminescent semiconductors, enhancing crime scene detection, with Amsterdam police already testing this technique that promises quicker and more sensitive on-site evidence collection...
Scientists fabricated an axion-like particle in a thin material, enabling them to study its behavior and potentially gain insights into dark matter, which could help detect real axions in nature.
Northwestern University scientists have discovered a hidden energy barrier in water splitting for hydrogen fuel production. The study reveals that water molecules must flip to allow electron transfer, requiring more energy than...
Crocodilians have survived for over 230 million years, including two mass extinctions, due to their exceptional adaptability in diet and habitat. Researchers examined fossilized teeth and skulls of 99 extinct and 20 living...
Venus Aerospace has integrated NASA-backed technology into its hypersonic Rotating Detonation Rocket Engine, claiming improved efficiency and smaller size over traditional systems, with a test flight planned for summer to...
The AudioDome speaker system, developed by Western University researchers, accurately recreates 3D soundscapes beyond human perception limits, enabling studies of auditory processing, despite minor speech degradation at higher...
Researchers have developed a system enabling drones to perform complex aerobatic maneuvers autonomously, outperforming human pilots. The framework uses onboard computing, maps, and visuals to navigate safely through obstacles...
A spiral galaxy resembling the Milky Way has been discovered just 1 billion years after the Big Bang, challenging our understanding of early galaxy formation. Named Zhúlóng, this massive system shows a mature structure with a...
UMass Amherst researchers have developed a laser-based technique using concentric metalenses to align 3D semiconductor chips with unprecedented precision. The method can detect misalignments as small as 0.017 nanometers,...
Scientists have designed a "cosmic radio" detector that could discover dark matter in 15 years by detecting axions, tiny particles thought to make up dark matter. The detector, called an Axion quasiparticle (AQ), operates at high...
Harvard researchers have successfully tested RoboBee's ability to safely take off and land on uneven surfaces like leaves. The team conducted experiments to understand leg oscillations, free-fall dynamics, and landing mechanics,...
Jupiter experiences hailstorms of "mushballs" - ammonia-water slushies covered in ice - along with intense lightning. This discovery, confirmed through 3D visualization, explains the uneven distribution of ammonia gas in...
Earth's ancient green oceans likely supported cyanobacteria growth, triggering the Great Oxygenation Event that transformed the atmosphere and oceans, paving the way for more complex life forms to develop.
