Phys.org / Resilient quantum sensor monitors Earth's magnetic field from space for 10 months
From navigation to solar weather forecasting, many different areas of research require space-based sensors to measure Earth's magnetic field as accurately as possible at any given moment. So far, however, existing sensors ...
Phys.org / Scurvy's skeletal fingerprint found in California's Late Holocene archaeological sites
A recent study published in the International Journal of Osteoarchaeology documented skeletal changes linked to scurvy in Late Holocene archaeological sites in California (500 BCE–1834 CE). The change observed shows the cascading ...
Phys.org / New alien-life test could help Mars and Europa missions read organic molecules
For decades, the search for life beyond Earth has revolved around a key question: What molecules should scientists be looking for on other planets or moons? A new study, published in Nature Astronomy, suggests that the more ...
Phys.org / Deep beneath Swiss Alps, researchers trigger 8,000 tiny quakes in controlled test
Researchers have made the ground shake in southern Switzerland, triggering thousands of tiny earthquakes in a monitored setting, as they seek to discover seismicity insights that could reduce risks.
Phys.org / How a single star can reshape an entire galaxy
Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New research from Leiden University shows that this is not a flaw, but a consequence of how galaxies behave—and ...
Phys.org / Shark face study uncovers 400-million-year-old blueprint shared across jawed vertebrates
Most of what scientists know about face development comes from studies in bony vertebrates such as mice, chickens, and zebrafish. However, their evolutionary counterparts, cartilaginous fishes, have remained largely unexplored. ...
Phys.org / Heat index maps uncover when city greening cools most—and when it can backfire
Tree shade is one of the fastest ways to make heat more bearable. It cuts direct sunlight, protects people walking or working outdoors, and remains essential for heat action plans. A new study by researchers from the Indian ...
Phys.org / Advanced construction techniques and domestic layouts discovered in Roman-Byzantine villages of Syria
Having weathered nearly 1,500 years of time and exposure, the remains of Roman-Byzantine villages in Syria have been the subject of recent architectural investigations, which reveal remarkable design features, local construction ...
Phys.org / Hubble survey sets up Roman's future look near Milky Way's center
The Milky Way's galactic bulge, the bulbous region that surrounds the galactic center, contains a dense collection of stars, planets, and other free-floating objects. This region has been studied for decades with numerous ...
Phys.org / Metagenomics and AI could unlock uncultivated bacteria and archaea
Advances in DNA sequencing have expanded our view of the microbial world, but the inability to cultivate most microbes has been a major constraint. Now, a systematic, predictive framework that combines existing genomic and ...
Phys.org / Machine learning proves that graphene is hydrophobic
For more than a decade, a fundamental mystery has surrounded graphene—the one-atom-thick "wonder material" known for its exceptional strength, conductivity, and transparency. Despite its seemingly simple structure, one basic ...
Phys.org / Brazilian microfossils interpreted as animal traces are actually algae and bacteria, research reveals
A reexamination of microfossils found in the Brazilian state of Mato Grosso do Sul shows that the marks previously interpreted as traces of worms or other small oceanic animals are actually communities of fossilized microscopic ...
