Early Human Presence in South America and Smiling Robots
Recent discoveries reveal butchered animal bones in Argentina indicating humans were present in southern South America 21,000 years ago, far earlier than previously believed. Additionally, Japanese scientists have developed a robot with a face that can 'smile' using human skin cells, showcasing breakthroughs in cosmetics and medicine.

Recent discoveries highlight key advancements in science. Fossil bones found in Argentina, showing signs of butchering, reveal that humans were present in southern South America some 21,000 years ago—far earlier than previously believed. The bones belonged to Neosclerocalyptus, a large, armored mammal.
In an unrelated breakthrough, Japanese scientists have succeeded in making robotic faces 'smile' using living skin tissue. Researchers at the University of Tokyo have grown human skin cells in the shape of a face and manipulated them to form a grin, pointing towards promising applications in cosmetics and medicine.
