Monk parakeets ease into new friendships, slowly approaching strangers to avoid aggressive encounters. Researchers watched how birds shared space, groomed each other, and escalated to deeper social bonds over time. The results show a clear pattern of cautious exploration echoing similar studies in other animals. Even for birds, making a...

Scientists may have found the planet that made the Moon
About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across space rocks. By examining subtle isotopic fingerprints in Earth and Moon samples, scientists have reconstructed Theia’s possible composition and birthplace.
Scientists capture stunning real-time images of DNA damage and repair
Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage flare up, track repair proteins rushing to the site, and see the moment...
Solar Superstorm Gannon crushed Earth’s plasmasphere to a record low
A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing position, researchers watched the plasmasphere shrink to a fraction of its usual size and take days to rebuild. The...
Scientists reveal how baby turtles navigate thousands of miles with a hidden magnetic sense
Researchers taught young loggerhead turtles to associate certain magnetic fields with feeding, prompting a distinctive dance when they recognized the signal. After a magnetic pulse briefly disrupted their ability to feel magnetic forces, the turtles no longer performed the dance. This showed that hatchlings use a touch-based magnetic sense to...
Scholars say most of what we believe about Vikings is wrong
Ideas about Vikings and Norse mythology come mostly from much later medieval sources, leaving plenty of room for reinterpretation. Over centuries, writers, politicians, and artists reshaped these stories to reflect their own worldviews, from romantic heroism to dangerous nationalist myths. Pop culture and neo-paganism continue to amplify selective versions of...
The surprising reason bees replace their queens
Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Field trials show that synthetic pheromone blends can prevent untimely supersedure, opening a path to more stable hive management.
AI detects a secret lion roar no one knew existed
Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a powerful new tool for conservationists racing to protect shrinking populations.
Fossils reveal a massive shark that ruled Australia in dinosaur times
Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks were experimenting with gigantic sizes far earlier than scientists believed, competing with the marine “monsters” of the dinosaur age.
Rapid fault healing could rewrite earthquake physics
Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the fault quickly regains strength. Lab experiments show that mineral grains can weld together under intense heat and pressure, acting like...
