Phys.org / Atlantic nurse sharks show faster growth patterns in Biscayne Bay than nearby Bimini, Bahamas
A new study from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science shows that juvenile Atlantic nurse sharks (Ginglymostoma cirratum) grow more rapidly as juveniles and reach smaller maximum ...
Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans
Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
Phys.org / Highly stable Cu₄₅ superatom could transform carbon recycling
After years of trying, scientists have finally created a stable superatom of copper, a long-sought-after chemical breakthrough that could revolutionize how we deal with carbon emissions.
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 / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions
New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...
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 ...
