New Images Reveal Young Solar Systems Filled With Secret Planets
New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building bodies. The structures often resemble our asteroid and Kuiper belts, hinting at unseen giant planets sculpting the dust. By comparing 51 systems, astronomers found clear trends linking star mass to disk mass and size. These images lay [...]

New Study Debunks Theory of “Incestuous Royalty” Ruling Ancient Ireland
Evidence from Newgrange suggests ancient Ireland was more egalitarian than once believed, with no clear signs of a ruling elite despite the discovery of an incest-born individual in the tomb. New research is challenging earlier claims that an incestuous ruling class governed the people of ancient Ireland more than 5,000 years ago. Scientists reexamined evidence [...]

35-Year-Old Air Samples Uncover Unexpected Changes in Nature’s Seasonal Rhythms
Old military air samples turned out to contain a hidden DNA archive showing that northern mosses now release spores much earlier than in the past. By examining DNA preserved in decades-old air samples collected by the Swedish Armed Forces, scientists at Lund University in Sweden have found clear evidence that northern mosses now release their [...]

NASA Satellite Captures First-Ever High-Res View of a Giant Pacific Tsunami
A rare satellite view captured a major Pacific tsunami in unprecedented detail, revealing wave behaviors scientists did not expect. A satellite designed to track the height of the ocean’s surface proved its capabilities when a powerful earthquake struck off the Kamchatka Peninsula in late July, sending a tsunami across the Pacific. According to researchers writing [...]

Ancient Pterosaurs Took Flight With Surprisingly Small Brains, Study Finds
A new study using advanced fossil imaging reveals that ancient pterosaurs may have mastered flight almost instantly when they first appeared, without the large brains that supported flight in birds. A team of researchers examining ancient fossils, led by an evolutionary biologist at Johns Hopkins Medicine, reports that a lineage of large reptiles living as [...]

Scientists Uncover New Evidence of Ancient Airbursts That Ravaged Earth Without Leaving Craters
Emerging evidence suggests Earth has endured far more hidden cosmic explosions than once believed. Touchdown airbursts, a form of cosmic impact that may occur more often than the crater-producing events known for wiping out the dinosaurs, are still not fully understood. UC Santa Barbara Earth Science Emeritus Professor James Kennett and his colleagues continue to [...]

A Massive Study Just Revealed a Surprising Effect of CBD on Dogs
Analysis of information from nearly 50,000 dog owners shows that pets given CBD supplements are generally older or dealing with medical conditions. Over time, these dogs were also reported to display lower-than-average aggression levels. In people, CBD is believed to offer relief for issues such as chronic pain, nausea, and inflammation. A new investigation suggests [...]

Scientists Develop New Plastics That Break Down Safely Instead of Polluting
Rutgers scientists have developed plastics that can be programmed to break down at specific rates by drawing on a natural principle. Their approach could provide a meaningful new way to tackle the growing problem of plastic pollution. Yuwei Gu was on a hike in Bear Mountain State Park in New York when an unexpected idea [...]

11-Year Study Reveals Eating These Plant Compounds Is Linked to Better Heart Health
A decade-long study links polyphenol-rich diets to slower increases in cardiovascular risk. People who often eat foods and drinks high in polyphenols, such as tea, coffee, berries, cocoa, nuts, whole grains and olive oil, may support better heart health over the long term. A research team from King’s College London reported that individuals who followed [...]

Simple Three-Nutrient Blend Rapidly Improves Autism Behaviors in Mice
A low-dose blend of zinc, serine, and branched-chain amino acids dramatically improved brain signaling and social behavior across three different mouse models of autism. Even brief treatment sparked real-time changes in neural connectivity, making this nutrient cocktail an intriguing path for future exploration. Low-Dose Nutrient Blend Shows Potential in Autism Mouse Models Researchers led by [...]

Powerful New DNA Editing Method Raises Hopes for Cures
Researchers created a highly efficient gene-editing method that fixes multiple DNA mutations in a single step. The breakthrough could revolutionize genetic medicine by making treatments for complex diseases faster and more inclusive. The Challenge of Treating Complex Genetic Diseases Some genetic disorders—such as cystic fibrosis, hemophilia, and Tay Sachs disease—involve multiple mutations across a person’s [...]

Scientists Teleport Entanglement Across Two Linked Quantum Networks in Historic First
Researchers at Heriot-Watt University have introduced a prototype quantum network that merges two smaller networks into a single, reconfigurable eight-user system capable of routing — and even teleporting — entanglement on demand. For many years, physicists have imagined a quantum internet: a global system that provides extremely secure communication and powerful new forms of computing, [...]
