Arctic Ocean Crossed a Nutrient Tipping Point Around 2009, Threatening the Polar Food Chain
Sea ice loss has triggered irreversible nitrate depletion in the Arctic Ocean since 2009, undermining the plankton foundation of the polar food web.
Webb Observes a Hot Jupiter's Daily Weather Cycle for the First Time, Revealing Rock Clouds That Form Every Morning and Dissolve by Nightfall
JWST has tracked the first complete daily cloud cycle on an exoplanet, finding that WASP-94Ab grows magnesium silicate clouds each morning and clears them each evening, while correcting a decade of skewed atmospheric measurements from Hubble.
400,000-Year-Old Tooth Proteins Link Homo Erectus to Denisovans and Leave a Trace in Modern Humans
A Nature study extracts 11 proteins from six Homo erectus teeth found in China, revealing a shared amino acid variant with Denisovans now present in some Southeast Asian and Oceanian populations.
JWST Peers at a Rocky Super-Earth's Surface for the First Time, Finding a Dark, Airless World That Looks Like Mercury
Astronomers used JWST's MIRI to directly study the surface geology of LHS 3844 b, a super-Earth 48.5 light-years away, revealing a basaltic, atmosphere-free world resembling Mercury — a first for exoplanet science.
HKU Researchers Uncover Piezoelectric Effect in Diamond Membranes, Upending a Century of Materials Science Consensus
University of Hong Kong team shows ultrathin polycrystalline diamond membranes generate voltage when bent, overturning the century-old classification of diamond as non-piezoelectric.
Researchers Fuse Silk Into Transparent, Lightweight Material Stronger Than Metal Alloys With 6G Potential
Teams at Imperial College London, University of Michigan, and Tufts University transformed natural silk threads into plastic-like materials that outperform metal alloys, resist punctures like carbon-fiber composites, and polarize terahertz light for potential 6G telecommunications use.
JWST Detects Methane in Atmosphere of TOI-199b, the First Temperate Giant Exoplanet to Have Its Chemistry Mapped
NASA's James Webb Space Telescope has characterized the atmosphere of TOI-199b, a Saturn-sized world 330 light-years away—the first temperate giant exoplanet studied in detail.
Rice and Weizmann Physicists Identify the Electronic Agents Behind Strange Metallicity in a Flat-Band Kagome Metal
Using atomic-resolution spectroscopy on Ni3In, researchers from Rice and Weizmann experimentally confirmed compact molecular orbitals as the drivers of flat-band quantum criticality.
Pressure Unlocks a Quantum Spin Liquid State in Kagome Material Y-Kapellasite, Ruling Out Disorder as Its Origin
A European team used muon spin spectroscopy under hydrostatic pressure to show that squeezing Y-kapellasite suppresses its magnetic order without any structural change, producing a clean quantum spin liquid state driven purely by geometric frustration.
Synthetic Biology Yields Protein Fibers That Dissolve and Reform, Offering a Recyclable Alternative to Synthetic Textiles
WashU engineers used synthetic biology to create SAM — a protein fiber combining mussel, spider silk, and amyloid sequences — that dissolves in formic acid within seconds and can be remade into equally strong fibers across multiple recycling cycles.
JWST Shows Neptune's Moon Nereid Is an Original Survivor, Not a Kuiper Belt Capture — Rewriting the Planet's Violent History
A Science Advances study using Webb data finds Nereid's icy composition rules out a Kuiper Belt origin, making it the sole intact remnant of Neptune's primordial moon system.
JWST Catches Two Post-Quasar Galaxies With Overmassive Black Holes 800 Million Years After the Big Bang
NIRSpec spectroscopy of COLA1 and NEPLA4 reveals black holes 400-800 times overmassive for their host galaxies, offering the first detailed look at the aftermath of early-universe quasar activity.
