Summary: In a pioneering study, researchers designed a wireless brain-spine interface enabling a paralyzed man to walk naturally again. The ‘digital bridge’ comprises two electronic implants — one on the brain and another on the spinal cord — that decode brain signals and stimulate the spinal cord to activate leg muscles. Remarkably, the patient experienced [...]
An anti-cancer gel promises to wipe out glioblastoma permanently, a feat that's never been accomplished by any drug or surgery. So what makes this gel so special? Scientists at Johns Hopkins University (JHU) have developed a novel gel that both eliminates brain cancer (glioblastoma) and keeps it from recurring. When they tested this anti-cancer [...]
Particles known as extracellular vesicles play a vital role in communication between cells and in many cell functions. Released by cells into their environment, these “membrane particles” consist of a cellular membrane carrying a cargo of specific signaling molecules, proteins, nucleic acids and lipids. Unfortunately, only tiny quantities of the vesicles are formed spontaneously [...]
The Australian Regenerative Medicine Institute (ARMI) at Monash University suggests that muscle wasting, known as sarcopenia, may be reversed in late-life The study utilized the African killifish as a model and found that muscles revert to an “early-life” state, slowing mortality. This discovery could potentially lead to interventions that slow down or even reverse age-related muscle [...]
The most recent version of ChatGPT, an AI chatbot developed for language interpretation and response generation, has successfully passed a radiology board-style exam, demonstrating both its potential and limitations, according to research studies published in the Radiological Society of North America’s journal. The latest version of ChatGPT passed a radiology board-style exam, highlighting the [...]
University of Missouri researchers designed a prototype of a small, lightweight active ‘metamaterial’ that can control the direction and intensity of energy waves. Professor Guoliang Huang of the University of Missouri has developed a prototype metamaterial that can control the direction and intensity of energy waves using electrical signals. The innovative material has potential [...]
Vanderbilt researchers are bolstering the fight against cancer with technology that enhances the effectiveness of T cells that attack tumors. The cutting-edge research was recently published in the journal Science Immunology. Cancers co-opt both the immune and cardiovascular systems to fuel their own growth, researchers say. They do this in part by forming new [...]
A species of ordinary gut bacteria that we all carry flourishes when the intestinal flora is knocked out by a course of antibiotics. Since the bacteria is naturally resistant to many antibiotics, it causes problems, particularly in healthcare settings. A study led by Lund University in Sweden now shows how two molecular mechanisms can work together [...]
Every skin flake, hair follicle, eyelash, and spit drop cast from your body contains instructions written in a chemical code, one that is unique to you. According to a new study, technology has advanced to the point that it's now possible to sift scraps of human DNA out of the air, water, or soil [...]
A recent study conducted by the Universities of Southampton and Oxford reveals a strong correlation between the incidence of long COVID and the level of area-specific deprivation. It found that individuals from the most deprived regions are 46 percent more likely to experience long COVID compared to those from less deprived areas. This research, which was published in [...]
