Groundbreaking research uses brain stimulation to restore touch in prosthetics. Precise, stable sensations bring natural-like feedback closer, improving motor control and quality of life.

Summary: Researchers are making strides in restoring touch sensations to prosthetic limbs through brain stimulation. By using electrodes in the brain’s touch center, they can evoke stable, precise sensations, even allowing users to feel the shape and motion of objects.

This breakthrough could enable prosthetic users to perform tasks requiring fine motor control with confidence. Long-term tests show consistent sensation locations, critical for real-world usability.

A small dose of low-power laser light activated dental stem cells in rat molars to generate dentin, one of the major components of teeth. The finding may lead to new approaches to develop low-cost, non-invasive therapies for treating dental disease and tooth damage.

Dentists currently use inert materials to repair damaged teeth. Tissue regeneration would be an attractive alternative, because inert materials can fail with time and don’t provide the full function of the tissue. Stimulating regeneration of teeth, however, is a major challenge. Teeth are composed of several parts, including the pulp at the core, dentin in the middle, and enamel on the surface.

Stem cells, found throughout the body, can give rise to specialized cells. Researchers have been able to coax stem cells to transform (differentiate) into many types of cells in the laboratory before infusing them into the body. But these techniques are time consuming and can bring unwanted side effects.

Tesla’s models once again made up a significant portion of the U.S. EV sector in 2024, outselling most other EVs combined.

Researchers have discovered how a cell surface protein called Aplp1 can play a role in spreading material responsible for Parkinson’s disease from cell-to-cell in the brain.

Promisingly, an FDA-approved cancer drug that targets another protein called Lag3 – which interacts with Aplp1 – blocks the spread in mice, suggesting a potential therapy may already exist.

In a paper published last year, an international team of scientists describes how the two proteins work together to help harmful alpha-synuclein protein clumps get into brain cells.

This article explores why the convergence of these technologies could represent the next quantum leap in artificial intelligence.

The soft metal bismuth may be a wonder material for electronics – particularly because of one surprising behaviour it displays when exposed to magnetic fields.

The James Webb Space Telescope.

The James Webb Space Telescope (JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope. It covers longer wavelengths of light, with greatly improved sensitivity, allowing it to see inside dust clouds where stars and planetary systems are forming today as well as looking further back in time to observe the first galaxies that formed in the early universe.
