Physicists say quantum mechanics may not need imaginary numbers after all
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also be used. The American Physical Society has also dedicated a “Highlight” to these findings in its Physics Magazine.
Stephen Hawking's black hole laws just got a major upgrade
Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones. The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO.
A 200-year-old physics experiment could help build future computers
Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered materials, they simply shine a laser at a tiny circular disc, producing stable swirling patterns in light that researchers believe could one day help power advanced data storage, communications, and computing technologies.
Scientists discover how the brain rewires itself to truly multitask
Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better at performing another task at the same time, challenging the long-held idea that humans only switch rapidly between tasks rather than truly multitask.
Scientists discovered the brain doesn't make decisions the way we thought
A new study suggests the brain begins making decisions much earlier than scientists previously thought. Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward. This more dynamic view of brain function could help engineers design future AI systems that think more like biological brains while using far less power.
Spider-like creatures help uncover the surprising origins of fatherhood
Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal care followed different evolutionary paths. The project, completed in just days with help from public data, shows how citizen science is transforming biological research on a global scale.
Deep-sea life has a secret food source scientists never expected
Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.
Scientists finally solved the mystery of Earth's greatest mass extinction
Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate change.
Physicists recreate black hole energy extraction in the lab
Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and could inspire new advances in optics, wireless communications, and quantum science.
Scientists warn invasive Asian mantises are threatening Europe's wildlife
Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expanding northward, where they prey on native insects, pollinators, and even small vertebrates while also reducing native mantis populations through deadly mating interactions.
Future moon landings could wipe out clues to how life began on Earth
A new study suggests spacecraft exhaust could quickly contaminate the moon's most scientifically valuable regions, potentially masking ancient clues about how life began on Earth. Researchers say future lunar missions should consider new ways to reduce and monitor this pollution before it becomes widespread.
Alzheimer's tau protein has a surprising secret role in memory
Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the recall of existing ones.
