Researchers at the University of Gothenburg have identified clear links between the composition of gut bacteria and frailty in older women. In cases of high frailty, with an increased risk of illness and death, gut bacterial diversity is lower and function is impaired. The study,
Brain implant uses temperature to switch neurons on and off
A research team led by Professor Il-Joo Cho of Korea University College of Medicine has developed a novel brain implant capable of bidirectionally modulating neural activity using temperature, opening new possibilities for next-generation brain-computer interfaces (BCIs) and trea
Myocardial infarction damage extending to remote regions of the ventricle could improve ca
A study provides significant evidence in the field of advanced cardiac imaging and clinical cardiology. It shows that the damage resulting from a myocardial infarction is not confined solely to the affected area, but may also extend functionally to remote regions of the ventricle
