Phys.org / How flying together helps Andean condors save energy
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce ...
Phys.org / Astronomers identify one of the universe's rarest black hole events
A team of astronomers at the University of North Carolina at Chapel Hill has observed an extremely rare "wandering" black hole located tens of thousands of light-years from the center of its galaxy. This finding could reshape ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Science X / Different flint, same toolmaking strategy: How Neanderthals adjusted their effort to get the same razor-sharp results
The Neanderthal toolkits found in two Ice Age caves near Le Moustier, in southwestern France, tell a surprising story. Even though the types of rock were very different—large, high-quality flint nodules at Le Moustier and ...
Science X / When darkness fell during the total solar eclipse, zoo animals responded in wildly different ways
Imagine a bright, sunny day suddenly turning dark as a solar eclipse sweeps across the sky. Even though humans have watched and recorded eclipses for thousands of years and now understand the science behind them, experiencing ...
Phys.org / AI-powered camera system offers low-cost way to monitor bumblebees, potentially other insects
Researchers have developed a low-cost, semi-automated, AI-driven method that uses remote cameras to survey bumblebees and potentially other insects. The new tool could have important implications for efforts to conserve declining ...
Phys.org / Scientists cut and rebuild molecules from the inside to create new chiral nanocarbons
Nanocarbons are molecular-scale carbon structures considered to be the building blocks for next-generation materials. Until now, scientists have built them by fusing small, flat carbon molecules together at their edges. Modifying ...
Medical Xpress / Stockpiled Ebola vaccines trigger antibody response against Bundibugyo virus in lab tests
A highly contagious Ebola virus species, Bundibugyo virus (BDBV), has driven several outbreaks since 2007, including the ongoing outbreak in the Democratic Republic of Congo and Uganda in 2026. Bundibugyo virus causes severe ...
Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds
When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...
Phys.org / Hubble shows star formation in Andromeda galaxy is winding down
A new study using data from NASA's Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, ...
Medical Xpress / Silver diamine fluoride treatment could halt cavities without shots, drilling or sedation
Every year, untreated tooth decay sends thousands of young U.S. children to emergency departments for dental problems doctors can't treat. Many eventually undergo surgery under general anesthesia, while others endure pain ...
Phys.org / How invasive rats rewire coral reef food webs to create winners and losers
Invasive rats on tropical islands are creating winners and losers among the tiny underwater animals near the bottom of the food chain that inhabit surrounding coral reefs. Scientists say the changes to these marine ecosystems ...
