Atomic Substitution Unlocks Inactive Sodium, Boosts Battery Energy
An atomic substitution in a phosphate cathode activated sodium ions that had remained electrochemically inactive. By changing the local coordination environment, the material delivered higher capacity and energy density. batteries
Chest X-Rays Detect Hidden Osteoporosis in Normal‑BMI Patients
Routine chest X-rays could help spot silent bone loss before fracture. More than half of confirmed abnormal bone-density cases were in people with normal BMI, a group conventional screening can miss. osteoporosis
Tabletop EUV Lithography Cuts 3D Patterning to Minutes
A tabletop EUV lithography device cuts semiconductor 3D patterning from days to minutes by printing multiple layers in parallel instead of one layer at a time. For now, it can pattern periodic structures. semiconductors
AI Designs Full Electrolyte Blends Matching Top Lithium Batteries
AI generated complete battery electrolyte formulations, including mixture ratios and concentrations, rather than selecting ingredients one by one. Several novel blends performed on par with leading lithium metal battery electrolytes. batteries
CTA 1 Pulsar Wind Nebula Shows Bent Jet, Perpendicular Torus
Chandra observations of CTA 1 resolve a compact pulsar wind nebula: a southern jet bends toward the southwest, a faint counter-jet extends north, and a torus sits nearly perpendicular to the jet axis. The bend hints at an external influence....
Teclistamab Delivers 70% 18‑Month PFS vs 27% Standard
Nearly 70% of patients with relapsed multiple myeloma on teclistamab stayed free of disease progression at 18 months, compared with about 27% on standard treatment. The advantage persisted in heavily pretreated patients. myeloma
Gut Microbes Drive Fish Carbon‑trapping Mineral Pellet Formation
A fish’s carbon-trapping mineral pellets may rely on a gut-microbe partnership rather than fish physiology alone. In Gulf toadfish, certain bacteria were abundant in both the intestine and the pellets. marinebiology
Antennae Galaxy Flare Too Small for Star Formation
A compact source in the Antennae galaxies varied over 13 days, constraining the emitting region to less than 13 light-days across. That scale and temperature do not fit ordinary star-forming activity, though one key signal is still absent. astronomy
Acute Stress Impairs Memory Replay, Not Learning
Acute stress did not block new learning. It weakened hippocampal replay of related memories, making it harder to connect separate events into a usable inference. memory
Ocrelizumab Cuts Disability Progression 30% in PPMS
In primary progressive MS, ocrelizumab was associated with a 30% lower risk of disability progression than placebo in a broad Phase III trial. Benefits were also seen in patients with advanced disease, though one subgroup stood out more. multiplesclerosis
Chikungunya Threat Expands to Temperate Europe, North America
Climate models suggest chikungunya risk could move north into temperate regions by 2100. North-central Europe and northeastern North America repeatedly emerged as hotspots, driven largely by shifting mosquito habitat. chikungunya
Expansion Microscopy Reveals Centrioles at Nanoscale with Standard Optics
A single expansion step enlarged centrioles about 8–9× while preserving delicate ultrastructure. That made nanoscale organization visible with standard optical microscopy, leaving one long-standing imaging barrier less fixed than it seemed. microscopy
Pygmy Rattlesnakes Face Heightened Fungal and Lungworm Threats
Pygmy rattlesnakes appeared especially vulnerable in southeastern snake surveys, with higher rates of snake fungal disease and snake lungworm than many other species. Infection risk also shifted with location. snakes
Maternal RSV Vaccine Prevents Infant Hospitalizations in Dallas
In Dallas, infant RSV hospitalizations split sharply by maternal vaccination status during the 2023–2024 season. None of the babies whose mothers were vaccinated were hospitalized, but access remained uneven. rsv
Tau Determines Long-Term Memory Storage in Mice
Tau appears to shape which brain cells store an experience, helping memories stay stable over time. In mice, it mattered for remote recall more than initial learning or short-term memory. neuroscience
