Phys.org / Could AI framework be the key to how collective cell intelligence works?
It has long been understood that groups of cells can perform complex tasks, such as navigating mazes or strategically colonizing new habitats, even though individual biological cells have only limited ability to respond to ...
Phys.org / Hidden life stories in fish ears: Fossilized otoliths reveal growth patterns
Fossilized fish ear stones—known as otoliths—can reveal far more than previously thought. In a recent study, a team of paleontologists from the University of Vienna demonstrated that a refined electron microscopy technique ...
Phys.org / Sniffer dogs tested in real-world scenarios reveal need for wider access to explosives
Dogs aren't just our best friends, they're also key allies in the fight against terrorism. Thousands of teams of explosive detection dogs and their handlers work 24/7 at airports, transit systems, cargo facilities, and public ...
Phys.org / A new attempt to explain the accelerated expansion of the universe
Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern physics. Because it cannot be fully answered using our current physical worldview, researchers ...
Phys.org / Record-breaking gamma ray burst seems to be caused by a black hole engulfed by a bloated star
On July 2, 2025, NASA's Fermi Gamma-ray Burst Monitor (Fermi-GBM) captured around three hours' worth of signals that appeared to come from the same source. When scientists compiled this data with signals picked up by multiple ...
Phys.org / Discovery of four stone megastructures could change our view of prehistoric societies
Scientists have discovered evidence of stone megastructures on the Karst Plateau on the border of Slovenia and Italy that were most likely built before the Late Bronze Age. These enormous structures have long, low walls that ...
Phys.org / Chicago's viral 'rat hole' was not made by a rat after all, new study finds
After existing quietly for over two decades on a Roscoe Village sidewalk in Chicago, a rodent-shaped indent became an internet sensation in 2024, when a tweet by comedian and writer, Winslow Dumaine, brought it into the public ...
Phys.org / Gaia provides a deep look into the galactic open cluster NGC 2506
Using ESA's Gaia satellite and NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers from the Ege University in Turkey and elsewhere have observed a galactic open cluster known as NGC 2506. Results of the observational ...
Phys.org / Sticky secrets: What ancient chewing gum is telling us about Neolithic communities
Ancient bones, artifacts and texts offer numerous insights into the past, as does the chewing gum that Neolithic people chewed on and spat out long ago. Analysis of lumps of birch bark tar from ancient settlements has revealed ...
Phys.org / Changing-look active galactic nucleus investigated by researchers
By analyzing the available data from various space observatories and ground-based telescopes, Indian astronomers have conducted a long-term multiwavelength study of a changing-look active galactic nucleus (AGN) known as NGC ...
Phys.org / Ancient lead exposure may have shaped evolution of human brain
An international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The research reveals that our human ancestors were periodically exposed to lead for over two million years, ...
Phys.org / Astronomers detect radio signals from a black hole tearing apart a star—outside a galactic center
An international team of astronomers has discovered the first tidal disruption event (TDE) producing bright radio emission outside the center of a galaxy. The findings are published in The Astrophysical Journal Letters.
