Lead-free capacitors convert heat into electricity in lab tests
The devices reached 3.7 joules per cubic centimetre across a 170 K span, with the strongest 10 K window at 40 to 50 °C.
European ADHD clinicians flag gaps in personalised care guidance
A survey of 1,441 clinicians in 23 European countries identifies three broad needs, including better treatment personalisation evidence and guidance in local languages.
Hip DXA scans closely tracked femur screw strength in cadaver study
In a laboratory test of 20 cadaveric femurs, hip-specific DXA matched newer bone-quality measures in tracking screw pullout strength, but the findings do not set a rule for patients.
Researchers find small, salt-sensitive alpha-synuclein assemblies
A peer-reviewed laboratory study reports a low-salt state that is finite, chemically fragile and reversible, while higher salt was linked to larger assemblies.
Study finds polymer-copper binder performs better in sulfur batteries
In laboratory lithium-sulfur cells, the copper-linked binder retained more capacity at fast test rates and reached 7.3 mAh per square centimetre at a 9 mg per square centimetre sulfur loading.
Fatty pancreas found in a third of pancreatic cyst patients
A matched case-control study found no statistically significant overall link to pancreatic cystic lesions, while a possible signal in the pancreatic tail needs larger studies.
Leaf-made zinc oxide nanoparticles show strong corrosion inhibition
In laboratory tests on carbon steel in 1 M hydrochloric acid, both routes showed high reported inhibition at 100 ppm, but they ranked differently across electrochemical tests.
Nanoparticles linked to calmer microglia and better stroke recovery
A study in cells and mice associated sulfonated nanoparticles with less inflammatory signaling and improved neurological measures after ischemic stroke.
Loss of CYLD linked to DNA repair shift and Olaparib sensitivity
Laboratory experiments tied chromosome 16q loss to lower CYLD, greater DNA damage and a repair pattern associated with greater sensitivity to the PARP inhibitor Olaparib.
Printed Hydrogels Turn Flat Designs Into Cell-Laden 3D Shapes
A peer-reviewed laboratory study matched programmed dome and saddle curvatures and reported high fibroblast viability while transformed structures retained integrity for up to 15 days in culture.
ALD dosing linked to stronger signals in MoS2 sensors
A peer-reviewed study reports an association between the oxide film formed before sulfurization and the coverage, defects and electrical output of flexible MoS2 devices.
AI Agent Study Finds Smarter Testing Can Beat More Rollouts
Preprint: A method that checks behavior-relevant tasks before accepting changes reported higher held-out scores, but its budget comparison was not compute-matched.
Robot AI Speeds Action Decoding in Simulated and Physical Tests
Preprint reports faster robot action decoding with similar or higher task success in simulations and physical tests, but notes a cold-start cost and successful-trial-only timing.
Smaller AI models’ mistakes guide stronger systems on tests
Preprint: A prompting method transfers failure patterns from weaker models, reporting modest gains with fewer target-model tokens.
Fermilab study projects rare-kaon yields and physics reach
Preprint: Simulations outline possible kaon yields and physics reach for a proposed Fermilab rare-kaon program.
Brain scan registration falls short for repeat-dose planning
Preprint study finds optimization-based methods were strongest overall, but case-to-case performance remained too variable for unmonitored dose accumulation.
Forest Tests Expose Weaknesses in Robot Navigation Systems
Preprint: A year-long subarctic field campaign found simple proprioceptive odometry stayed comparatively robust as sensor methods degraded.
Preprint finds weak topology can admit chaos in linear maps
The two-dimensional classification separates real and complex matrix cases, while a Jordan-block result needs checking.
Adaptive solver leads reported tests of hard optimization problems
Preprint reports complexity guarantees and stronger numerical results for a method that changes penalty growth as constraints improve.
