Scientists at Saarland University’s Homburg Campus have developed a pioneering robot-assisted procedure for joint replacement surgery. Their approach removes the need for bone pins and external infrared cameras in procedures such as knee replacement surgery. Led by Professor Stefan Landgraeber, Director of the Department of Orthopaedics and Orthopaedic Surgery at the University Medical Center, and research associate Philipp Winter, the project seeks to make orthopedic surgery both safer and less invasive.

Bodily functions rise and decline with age, and the brain is no exception. However, the exact trajectory of our brain activity during controlled behavior remains unclear. A recent study published in Science Bulletin by Zhenghan Li et al. explores this issue. They found that brain activities related to cognitive control follow an inverted U-shape in the whole lifespan, peaking between ages 27 and 36. These insights may help develop strategies for enhancing brain health and optimizing cognitive function across various age groups.
