SETI checked 3 I/ATLAS for alien signals " Here's what they found
18+ hour, 17+ min ago (1044+ words) SETI scientists scanned interstellar object 3 I/ATLAS for radio technosignatures and found no evidence of artificial signals. (CREDIT: AI-generated image / The Brighter Side of News) A comet from another star system does not arrive every year. That is part of…...
New tachyon theory could unlock the secrets of time travel and causality
20+ hour, 33+ min ago (1095+ words) A new tachyon theory argues faster-than-light particles may fit within relativity without the old paradoxes about time and causality. (CREDIT: Wikimedia / CC BY-SA 4. 0) Faster-than-light particles have spent decades in physics as both temptation and warning. They offered a way to…...
Ancient Britons likely transported Stonehenge's Altar Stone 700 kilometers from Scotland
20+ hour, 33+ min ago (986+ words) New modelling by Dr Anthony Clarke and his team suggests Stonehenge's Altar Stone was not carried to southern England by ice alone. Humans likely moved it. (CREDIT: Curtin University) Stonehenge has always invited big questions, but one of its most…...
The explosive fate of a collapsing star depends on neutrinos
1+ day, 9+ hour ago (1150+ words) New simulations show fast flavor conversion can either help or hinder core-collapse supernova explosions. (CREDIT: AI-generated image / The Brighter Side of News) A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in…...
Iron meteorites unlock secrets of the early solar system and Earth's origin
1+ day, 16+ hour ago (1000+ words) Iron meteorites suggest Earth's nitrogen and phosphorus may have come from early inner solar system planetesimals. (CREDIT: NASA/FUSE/Lynette Cook) The ingredients that help make a planet livable did not necessarily come from where many scientists once thought. A…...
GPS study tracks how animals respond to people across America
2+ day, 14+ hour ago (1290+ words) Scientists tracked 37 species and found animals react strongly to human movement, often in unexpected ways. (CREDIT: Shutterstock) Roads, cities and farms have reshaped much of the natural world. For decades, scientists believed those physical changes explained most wildlife behavior near…...
Fossil discovery solves 500-million-year-old mystery about the dawn of animal life
2+ day, 16+ hour ago (763+ words) Tiny honeycomb-like colonies from southern China have opened a long-running gap in the story of animal life. For decades, bryozoans seemed oddly absent from the Cambrian explosion, the burst of diversification that filled ancient seas with most major animal groups....
Six-satellite 'Storm Wall' could stop dangerous solar storms before they hit Earth
2+ day, 20+ hour ago (1173+ words) Simulations suggest six spacecraft could weaken geomagnetic storms before they disrupt Earth's satellites, GPS, and power grids. (CREDIT: AI-generated image / The Brighter Side of News) The most dangerous weather around Earth does not come with clouds. It comes from the…...
Robot fish helps explain how real fish learned to move on land
3+ day, 12+ hour ago (1227+ words) Fish that flop across land may be using one of evolution's oldest movement tricks, a simple gait shared across distant species. By copying it in a robot, researchers traced a common mechanical pattern that may echo how vertebrates first began…...
World's largest scorpion lived in Britain 415 million years ago
3+ day, 14+ hour ago (1249+ words) Fossils from Britain confirm Praearcturus gigas was a giant scorpion more than a meter long in the Early Devonian. (CREDIT: Wikimedia / CC BY-SA 4. 0) A giant predator was stalking what is now Britain roughly 415 million years ago, long before forests spread…...
