Phys.org / When mothers make the winners: How alpha female lineages dominate hyena clans
In mammals, males are usually stronger and more competitive than females. Males also show greater inequality in reproductive success—the number of offspring they produce—than females. In spotted hyenas, the opposite is true: ...
Phys.org / JWST captures rare glimpse of early black hole growing inside network of young galaxies
Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
Phys.org / Chocolate syrup-like fluid stores multiple interacting memories
Animals and electronic devices aren't the only things with memory. Materials can retain memories of past deformations in their microscopic structure. A common example is a crease in a sheet of paper that has been folded then ...
Phys.org / Not every meal has the same impact: Researchers reveal the hidden footprint of our food
Leiden environmental researchers have mapped the environmental footprint of different diets and revealed which population groups have the greatest impact through their food choices. Their findings show where efforts to make ...
Phys.org / Exploring the lost golden age of language diversity before expanding empires drove a global decline
Today, people speak or sign around 7,500 languages. Yet this figure provides only a snapshot of a constantly changing history. How many languages existed before written records? Did agriculture reduce linguistic diversity ...
Phys.org / Engineers observe quantum heat waves at room temperature
Efficient heat management in solids is key to advancing the next generation of electronics. However, wave-like heat movement—known as phonon focusing—had been observed only at extremely low, or cryogenic, temperatures, limiting ...
Phys.org / Plant diversity boosts natural pest control in farms, while forests and grasslands follow different rules
Plant diversity has long been regarded as key to stable and resilient ecosystems. However, until now, little has been understood about why it has different effects in agricultural areas than in grasslands or forests. An international ...
Phys.org / Destructive crop caterpillar harbors fungi that can degrade Styrofoam
A moth caterpillar identified by the agribusiness sector as one of the most destructive pests of soybean, cotton and corn crops may harbor fungi and bacteria in its gut that can degrade expanded polystyrene, also known as ...
Phys.org / Global map reveals mining's uneven toll on forests and biodiversity
A new study led by Japanese researchers from Tohoku University and the National Institute for Environmental Studies (NIES) reveals that some of the minerals most essential for green technologies may have a significant negative ...
Phys.org / Colorado basins supplying 70% of Lake Powell's water face major midcentury shortages
If the Colorado River Basin is the lifeblood of the American Southwest, keeping the region's agricultural, ecological and economic systems thriving, Colorado's West Slope River basins could be considered the heart. Together, ...
Phys.org / Programmable platform enables on-demand design of plant immune receptors against crop pathogens
Crop production faces threats from plant pathogens. Traditional disease-resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to particular pathogens. However, rapidly evolving ...
Phys.org / Simple circuit brings topological insulators closer to practical electrical measurement standards
Researchers at the University of Würzburg have succeeded in detecting exceptionally robust electrical transport in a topological insulator. This could lead to new metrological applications. The work is published in the journal ...
