Phys.org / Juno finds final missing auroral signature from Jupiter's largest moons
Jupiter hosts the brightest and most spectacular auroras in the solar system. Near its poles, these shimmering lights offer a glimpse into how the planet interacts with the solar wind and moons swept by Jupiter's magnetic ...
Phys.org / Marsquakes indicate a solid core for the red planet, just like Earth
Scientists revealed Wednesday that Mars' innermost core appears to be a solid hunk of metal just like Earth's.
Phys.org / How the Slavic migration reshaped Central and Eastern Europe
The spread of the Slavs stands as one of the most formative yet least understood events in European history. Starting in the 6th century CE, Slavic groups began to appear in the written records of Byzantine and Western sources, ...
Phys.org / Nutrient-enriched seagrass can store more carbon, but too much nutrition—especially nitrogen—can be its undoing
Seagrass has the potential to be one of the world's most effective sponges at soaking up and storing carbon, but we don't yet know how nutrient pollution affects its ability to sequester carbon.
Phys.org / Soft materials hold onto 'memories' of their past for longer than previously thought
If your hand lotion is a bit runnier than usual coming out of the bottle, it might have something to do with the goop's "mechanical memory."
Phys.org / Safe underground carbon storage would only reduce warming by 0.7°C, analysis finds
For the first time, a study maps safe areas that can practically be used for underground carbon storage, and estimates that using them all would only cut warming by 0.7°C. The result is almost ten times lower than previous ...
Phys.org / Sperm bots roll out: Cells coated with magnetic nanoparticles could transform future of fertility
A team of researchers at the TechMed Center of the University of Twente has transformed real sperm cells into tiny, magnetically controlled microrobots. These sperm bots can now be tracked in real time using X-ray imaging, ...
Phys.org / Crystalline material conducts heat even worse than glass and water—and that's promising
A research team from Aarhus University, Denmark, has measured and explained the exceptionally low thermal conductivity of the crystalline material AgGaGe3Se8. Despite its ordered structure, the material behaves like a glass ...
Phys.org / Soot's climate-altering properties change within hours of entering atmosphere
Billions upon billions of soot particles enter Earth's atmosphere each second, totaling about 5.8 million metric tons a year—posing a climate-warming impact previously estimated at almost one-third that of carbon dioxide.
Phys.org / Global methane levels continue rising as trade and developing regions fuel growth
The world's methane emissions continue to rise steadily with no signs of slowing, as global trade contributes some 30% to the total amount of the greenhouse gas swirling around the planet, a new study reveals.
Phys.org / Here we glow: New organic liquid provides efficient phosphorescence
The nostalgic "glow-in-the-dark" stars that twinkle on the ceilings of childhood bedrooms operate on a phenomenon called phosphorescence. Here, a material absorbs energy and later releases it in the form of light. However, ...
Phys.org / Engineered bacteria glow green to quickly detect microplastics in water samples
Microplastics are tiny, plastic fragments—many too small to see—found in the air, soil and water. Measuring their abundance in nature can direct cleanup resources, but current detection methods are slow, expensive or ...
