Medical Xpress / Why children often eat less in hot weather—and when parents should worry
If your child suddenly starts picking at meals during a spell of hot weather, it can be unsettling. But a smaller appetite for a few days can be a normal response to heat, particularly if your child is drinking well, has ...
Phys.org / Oldest known giant rock scallop bead suggests California coastal trade began millennia earlier
Archaeologists have discovered two giant rock scallop beads that push back the clock on the first appearance of these high-status ornaments. The discovery shows that these prized marine beads were traded hundreds of miles ...
Phys.org / Californians are twice as likely as Louisianans to be childfree—but demographics tell more of the story
Across the United States, the number of people who do not have and do not want to have children is growing. While they are twice as likely to live in California as Louisiana, individual demographic characteristics are the ...
Tech Xplore / Electrochemical method could make seawater a low-cost source of magnesium salts
Magnesium supplements are gaining popularity to treat conditions such as insomnia, migraines and constipation. Most magnesium salts are extracted from rocks by crushing and heating them, which requires a lot of energy. Now, ...
Tech Xplore / New model bridges ferroelectric physics and circuit modeling
A new physics-based analytical model can accurately predict ferroelectric behavior under real-world, complex voltages, according to a study led by University of Michigan Engineering. The model bridges the longstanding gap ...
Phys.org / Weather prediction hits a theoretical 129-day ceiling
Prediction is the goal and test of all science, one might argue. Meteorologists have been curious about the inherent limits of weather forecasting ever since the dawn of numerical weather prediction in the late 1950s.
Medical Xpress / Got ice‑cream brain freeze? Here's what is happening
With temperatures forecast to reach around 37°C (99°F) in places, reaching for an ice cream or an icy drink might seem like an excellent idea. There is, however, one small hazard to eating your frozen treat with too much ...
Phys.org / Chemical fingerprints reveal hidden binary pasts of massive stars
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...
Phys.org / Safe havens protect Australian mammals from invasive predators. Why aren't they working for other animal groups?
Feral cats and foxes now roam across almost all of Australia. These predators are a major reason why many species have been driven to extinction.
Phys.org / Radiation vest tested on NASA moonshot can cut astronauts' exposure in solar storms, study suggests
A new study suggests a protective vest tested on a manikin during NASA's first Artemis moonshot could drastically cut the radiation exposure of lunar astronauts during severe solar storms.
Phys.org / Tropical trees show unexpected drought adaptability across Puerto Rico's rainfall extremes
Tropical forests store enormous amounts of carbon and harbor most of the world's terrestrial biodiversity, but scientists fear that increasingly severe droughts threaten their ability to survive and continue absorbing carbon ...
Phys.org / Rangers and scientists map vulnerable reefs in the remote Groote Archipelago
For thousands of years, the Anindilyakwa people have lived in deep connection with the waters surrounding Groote Eylandt, a remote island in the Gulf of Carpentaria.
