Researchers have developed a method to reconstruct videos based on the brain activity of mice, opening up new possibilities for studying how the brain transforms visual signals into internal representations. This work provides deeper insight into the differences between objective reality and the way the brain perceives the world.
Scientists are studying universal paralogs—ancient genes preserved in all living organisms—to learn more about the earliest stages of evolution and the origins of life on Earth. New analytical methods make it possible to reconstruct the functions of these genes and bring us closer to understanding how the first cells emerged.
A new study has revealed that the first migrants from Africa were small in stature and had archaic features, rather than being large, athletic individuals as previously believed. This finding changes our understanding of the early evolution and migrations of Homo erectus.
