A brain implant enables a man with ALS to communicate with his family

Leave a Comment / Applied Science, Neuroscience /

A study published on Monday (June 15) in the journal Nature reports that a brain implant is enabling a patient with amyotrophic lateral sclerosis (ALS) to communicate with his family and even continue working. In 2023, surgeons implanted a device with 256 microelectrodes into Casey Harrell’s brain and installed the system in his home. Diagnosed […]

Ultrathin 1-nanometer nanotubes enable smaller electronic devices

Leave a Comment / Applied Science, Neuroscience /

Researchers in Japan, including the University of Tokyo, have created ~1 nm-wide semiconducting nanotubes—about 100,000× thinner than a human hair—by growing molybdenum disulfide inside boron nitride tubes to form stable, uniform structures at an extreme scale. The results validate long-standing theoretical predictions about ultrathin nanotube behavior and may open new possibilities for ultra-miniaturized electronics. The

Japan’s new electric spoon makes food taste saltier without actual salt

Leave a Comment / Applied Science, Neuroscience /

Known as the Electric Salt Spoon, the device was developed through a collaboration with researchers from Meiji University and went on sale in Japan in May 2024 in limited numbers. The spoon uses a mild electric current to concentrate sodium ions on the tongue’s taste receptors, making food taste saltier without adding extra salt. Users

A nasal spray for stroke patients can deliver medication to the brain without surgery

Applied Science, Neuroscience /

Scientists have developed the world’s first nanoparticle nasal spray for stroke, allowing brain drug delivery without surgery or injections. By bypassing the blood-brain barrier, it enables rapid use after symptoms appear, supporting early treatment, protecting brain cells, and reducing complications. The breakthrough was developed by researchers at The University of Hong Kong’s LKS Faculty of

Scientists can block pain signals before they reach the brain

Applied Science, Neuroscience /

For centuries, medicine has tried to manage pain by reducing symptoms or blocking nerve signals. Now, researchers are adopting a more radical approach: they are preventing pain before the brain becomes aware of it. Importantly, this work is already being tested in laboratories developing real-time neural technologies, not just remaining theoretical. Traditionally, pain treatment has

3D-printed brain sensors may enable personalized neural monitoring

Applied Science, Neuroscience /

Soft, flexible electrodes tailored to the brain’s surface may improve neural monitoring and treatment of neurodegenerative diseases. Unlike rigid, one-size-fits-all sensors, the team developed a 3D-printing method to create stretchable electrodes that match each brain’s unique shape. Using MRI data from 21 patients, the researchers created detailed brain models and customized electrode designs before printing

Researchers found evidence that memory can occur outside the brain

Applied Science, Neuroscience /

Many people assume that memory belongs only to the brain, but recent findings suggest this idea may be too limited. Research conducted at New York University indicates that certain ordinary human cells outside the brain are also capable of learning and retaining information. Cells exposed to learning-like signals behaved similarly to neurons, showing stronger responses

Startup pitches cloned bodies for brain transfer

Applied Science, Neuroscience /

Since the mid-1990s, cloning has fascinated scientists, beginning with Dolly the sheep, the first mammal cloned from an adult cell in 1996. While animal cloning has advanced significantly, applying the same methods to humans remains highly controversial because of both ethical concerns and major scientific risks. Researchers have only managed limited progress so far, such

Scientists Create Super Vision Lenses That Work With Eyes Closed

Applied Science, Neuroscience /

Scientists have created infrared contact lenses that reportedly enable people to see in the dark — and even more surprisingly, while their eyes are closed. The University of Science and Technology of China team created wearable lenses with flexible polymers and nanoparticles that enable night vision without goggles. The findings were published on May 22
