Scientists have successfully grown lab-created human brain tissue inside living mice, creating a remarkable new model that could help researchers understand neurological diseases, brain development, and potential treatments. The experiment, led by researchers at Stanford University and published September 16, 2026, represents a major advance in the use of human brain organoids for neuroscience research. The researchers transplanted laboratory-grown human brain tissue into specially engineered mice whose cerebral cortex had largely failed to develop. The human tissue then expanded, developed...Click for full post

A remarkable fossil discovery in North Dakota has given scientists something they have never had before: a sequence of footprints believed to have been left by an adult Tyrannosaurus rex. For decades, paleontologists have studied T. rex bones and isolated footprints to understand the world's most famous dinosaur. Now, researchers have discovered what appears to be the first known trackway made by an adult T. rex, providing a rare glimpse into how the giant predator actually moved across the landscape....Click for full post

Mercury may be getting smaller—and scientists now think they underestimated just how much the tiny planet has contracted. A new study suggests that Mercury could have shrunk by as much as 14.5 miles (23 kilometers) in diameter since its formation, potentially 30% more than previous estimates. The discovery is giving planetary scientists a fresh look at what is happening inside the solar system's smallest planet and could help explain how Mercury evolved over the past 4.5 billion years. Mercury Is...Click for full post
