Phys.org / Unified framework sorts spacetime fluctuations for quantum-gravity experiments
A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear in many attempts to ...
Phys.org / Are your memories illusions? New study disentangles the Boltzmann brain paradox
In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics and cosmology known ...
Phys.org / Massive black hole mystery unlocked by researchers
It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...
Phys.org / Bionic LiDAR system achieves beyond-retinal resolution through adaptive focusing
In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest (ROIs) while maintaining ...
Phys.org / Compact electron accelerator offers new approach for treating PFAS-contaminated water
So-called forever chemicals or PFAS compounds are a growing environmental problem. An innovative approach to treating PFAS‐contaminated water and soil now comes from accelerator physics: high‐energy electrons can break ...
Phys.org / Neanderthals took reusable toolkits with them on high-altitude treks through the Alps
When Neanderthals in Italy were crossing the Alps, it's likely they took refuge in high-altitude bear caves. A new study of stone tools in Caverna Generosa, a cave sitting 1,450 meters up in the mountains, found that these ...
Phys.org / Too much entanglement? Quantum networks can suffer from 'selfish routing,' study shows
Quantum technologies, systems that process, transfer or store information leveraging quantum mechanical effects, could tackle some real-world problems faster and more effectively than their classical counterparts. In recent ...
Phys.org / World's oldest rock art holds clues to early human migration to Australia
A hand stencil on the wall of a cave in Indonesia has become the oldest known rock art in the world, exceeding the archaeologists' previous discovery in the same region by 15,000 years or more.
Phys.org / How European city life is continually rewriting insect DNA
Cities are known to shape the evolution of wildlife within them, but according to a study of European cities published in the journal Proceedings of the Royal Society B: Biological Sciences, this is not a one-off event. Rather ...
Phys.org / Largest canine gut microbiome catalog reveals hundreds of new bacterial strains
Researchers at the Waltham Petcare Science Institute in the UK recently revealed a complete taxonomic and functional catalog of the canine gut microbiome after analyzing samples from 107 healthy dogs across the U.S. and Europe. ...
Phys.org / Astronomers discover a companion cluster to Czernik 38
Astronomers from the National Research Institute of Astronomy and Geophysics (NRIAG) in Cairo, Egypt, have investigated a young open cluster known as Czernik 38. As a result, they found a new open cluster, which turns out ...
Phys.org / Metal clumps in a quantum state: Physicists place thousands of sodium atoms in a 'Schrödinger's cat state'
Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, physicists from the University ...
