Phys.org / How do you get middle schoolers to eat more fruit? Give them smoothies
At lunchtime in rural Maine middle schools, University of Maine researchers stood at two points in the cafeteria.
Tech Xplore / Study reveals substantial misdirection in EU automotive regulation
CirculaTUM, the interdisciplinary research network of the Technical University of Munich (TUM), has been researching the decarbonization of the automotive sector since the beginning of the year. The findings of the most comprehensive ...
Tech Xplore / Social media companies are trying harder to know which users are kids
Of the child safety measures agreed to in Meta's landmark legal settlement, no category contains more detailed requirements than its commitments on age assurance—and for good reason. No matter how well the protections work, ...
Phys.org / When exposed to air, new nanomaterial becomes magnetic at high temperatures
While fridge magnets are great for saving favorite recipes, modern magnetic materials are useful for improving fiber optics or quantum information science technology. On most fridge magnets the atoms are arranged in a repeated ...
Phys.org / Engineered bacteria offer a new way to accelerate rock weathering for carbon removal
Rock weathering, the breakdown and dissolving of rocks and minerals caused by their exposure to water, air and biological life, is a major regulator of Earth's atmospheric CO2 levels and climate. Throughout Earth's history, ...
Phys.org / An anomalous return of the Odden ice tongue suggests unusual Arctic conditions
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the ...
Phys.org / Aboriginal artists painted giant ancestral beings as colonization arrived, study finds
Slithering across the ceiling of an Australian rock shelter is a giant snake with a crocodile-like head, razor-sharp teeth and a long tongue. It's more than 6 meters (20 feet) long, making it one of the largest Rainbow Serpent ...
Phys.org / Interstellar travel V: Warp drives, wormholes, and halo drives
Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments ...
Phys.org / Physicists finally put Feynman's path integral to the test
For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Medical Xpress / How cannabis legalization affects substance use
The legalization of cannabis affects substance use, with the potential for both negative and positive effects on public health, a new McGill-led study found.
Phys.org / Mercury's crust points to deeper, hotter volcanic origins than expected
The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, ...
