Researchers Say They’ve Found the Truth About Thomas Jefferson: New DNA Evidence Explained

For more than two centuries, historians have debated one of the most controversial questions surrounding Thomas Jefferson: Did the third president of the United States father children with Sally Hemings, an enslaved woman at Monticello? Now, researchers involved in a long-running Smithsonian investigation say they have found what they describe as the most definitive scientific answer yet. A new genomic investigation, detailed by Smithsonian scholar Richard Kurin in his forthcoming book History by a Hair, reportedly used DNA recovered from...Click for full post

Scientists Grow Human Brain Tissue Inside Mice: A Breakthrough in Neuroscience

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

CDC Changes Measles Death Reporting as Pennsylvania Cases Rise

The Centers for Disease Control and Prevention (CDC) has changed how it reports measles-related deaths at a time when Pennsylvania is experiencing one of the largest measles outbreaks in the United States in decades. The reporting change comes as Pennsylvania continues to confirm new measles infections. As of September 11, the Pennsylvania Department of Health reported 676 confirmed measles cases across 37 counties, along with 124 hospitalizations and two measles-associated deaths in its official statewide data. (Pennsylvania.gov) A third death...Click for full post

First Adult T. rex Trackway Found in North Dakota: Scientists Discover 66.5-Million-Year-Old Footprints

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 Shrinking Faster Than Scientists Expected

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

Have Scientists Discovered a Dark Matter Particle? Scientists Detect a Mysterious Signal Deep Underground

For nearly a century, scientists have known that something invisible appears to be shaping the universe. Now, researchers may have captured the most intriguing clue yet. The LUX-ZEPLIN (LZ) experiment, located nearly a mile underground in South Dakota, has detected a single unusual particle interaction that scientists have been unable to explain using known background processes. The event is consistent with what researchers might expect if a hypothetical dark matter particle collided with an atomic nucleus. It is an extraordinary...Click for full post
