Phys.org / Amazon Leo satellites exceed brightness limits, study finds
Seeing a satellite zip across the night sky can be a fascinating sight. However, what may be spectacular for people on the ground is becoming a major problem for astronomers. A new study published on the arXiv preprint server ...
Phys.org / The Great Mongolian Road: Japanese Imperial Army maps reveal first detailed documentation
In a study published in the Journal of Historical Geography, researchers Dr. Chris McCarthy and his colleagues have documented, for the first time, the Great Mongolian Road, a major yet understudied east-west caravan route ...
Phys.org / People are swayed by AI-generated videos even when they know they're fake, study shows
Generative deep learning models are artificial intelligence (AI) systems that can create texts, images, audio files, and videos for specific purposes, following instructions provided by human users. Over the past few years, ...
Phys.org / Milky Way is embedded in a 'large-scale sheet' of dark matter, which explains motions of nearby galaxies
Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local Group of galaxies (which ...
Phys.org / Higher water levels could turn cultivated peatland in the North into a CO₂ sink
In its natural state, peatland is one of the largest carbon stores in nature. This is because the soil is so waterlogged and low in oxygen that dead plant material breaks down very slowly. The plants do not fully decompose ...
Phys.org / NASA's Juno measures thickness of Europa's ice shell
Data from NASA's Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter's moon Europa. Using the spacecraft's Microwave Radiometer (MWR), mission scientists determined ...
Phys.org / Ancient Martian beach discovered, providing new clues to red planet's habitability
New findings from NASA's Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface water in a Martian crater that once held a vast lake—considerably expanding the timeline for potential ...
Phys.org / Novel nanomaterial uses oxidative stress to kill cancer cells
Scientists at Oregon State University have developed a new nanomaterial that triggers a pair of chemical reactions inside cancer cells, killing the cells via oxidative stress while leaving healthy tissues alone. The study ...
Phys.org / Ochre used in ancient graves in Finland reflects identity of deceased
Roughly 5,500–6,000 years ago, the area including present-day Finland was inhabited by hunter-fisher-gatherers living in small village-like clusters. Traveling via waterways, these people established permanent fishing systems, ...
Phys.org / Thinking on different wavelengths: New approach to circuit design introduces next-level quantum computing
Quantum computing represents a potential breakthrough technology that could far surpass the technical limitations of modern-day computing systems for some tasks. However, putting together practical, large-scale quantum computers ...
Phys.org / Did You Feel It? Expanding use of an earthquake crowdsourcing tool
The U.S. Geological Survey (USGS) crowdsourcing platform Did You Feel It? (DYFI) rapidly transforms people's earthquake shaking intensity experiences into detailed maps of damage extent. While the tool's reach is global, ...
Phys.org / Gold 'supraballs' nearly double solar energy absorption in tests
Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold nanospheres, named supraballs, ...
