Paralyzed man feels objects through another's hand via brain implant
AI에 의해 보고됨
A man paralyzed from a diving accident has used a brain implant to control and sense another person's hand as if it were his own. The technology, developed by researchers in New York, allowed him to distinguish between objects by touch and assist another paralyzed individual. This breakthrough could aid rehabilitation and raise ethical questions about remote body control.
Scientists develop LED therapy to kill cancer cells safely
Researchers from the University of Texas at Austin and the University of Porto have created a cancer treatment using LED light and tin nanoflakes that destroys up to 92% of skin cancer cells without harming healthy tissue. This affordable alternative to traditional therapies relies on near-infrared photothermal principles. The breakthrough, published in ACS Nano, aims to make targeted cancer care more accessible worldwide.
