AI models trained during safety fine-tuning to say they have no consciousness also systematically downgrade their attribution of mind to animals and natural objects, their religious beliefs, and even their subjective well-being. A team from Google and the University of Chicago reveals this unexpected ripple effect of alignment through geometric analysis of internal representations.
In fusion reactor material testing, femtosecond electron camera observations have revealed that copper does not instantly collapse even when it exceeds its predicted limit temperature, but instead melts gradually. This discovery overturns the assumptions behind conventional simulations and could improve the accuracy of heat-resistant material screening.
Moonshot AI's PerceptionBench is a 3,000-question benchmark that strips away reasoning and knowledge to measure visual perception alone. Evaluating 16 state-of-the-art models, the top score was just 59.7%. It quantitatively reveals how similar overall scores mask uneven capabilities, and how what looks like a 'reasoning failure' is often actually a perception failure at its root.
A ton of discarded circuit boards contains roughly 200 times more gold than natural ore. Solvent extraction, the technique used to mine this "urban ore," has always demanded heavy consumption of acids and bases. Now a research team at the University of Illinois Urbana-Champaign has demonstrated a design principle for a single molecule with built-in charge that fully electrifies the extraction cycle—cutting chemical reagent use by up to 100-fold while achieving 89% gold recovery.
A University of Minnesota research team has synthesized semiconductor-grade pyrite single crystals from low-grade taconite ore—traditionally used as steelmaking feedstock—without any additional purification. The discovery that pyrite is "immune" to impurities shakes the long-held assumption that semiconductor materials require high-purity starting materials.
Under shock compression at the trillion-pascal scale, microcrystalline diamond melted at roughly 7,300 K without leaving a clear diffraction signature of the BC8 phase. We unpack the detection limits and a conditional prediction of a threefold fusion yield gain.
An Argonne National Laboratory team has shown through experiments and multipole analysis that when the rotation angle of four nanomagnets exceeds 45°, the energy relaxation of the system switches from probabilistic to deterministic. This provides a new principle for designing output certainty through geometric arrangement alone, offering a path toward ultra-low-power computing with artificial spin ice.
A Rice University team has demonstrated for the first time that sub-nanometer wrinkles in graphene produce spontaneous electric polarization. The finding opens a path to controlling graphene's electrical properties through curvature alone, without chemical modification, with polarization density up to seven orders of magnitude larger than in conventional systems.
While China imposes sweeping controls on the export of rare earth processing technology, it has for the first time incorporated the field into academic cooperation with Iran. A small-scale workshop worth 30,000 yuan has become a geopolitical touchpoint connecting the structure of US-China resource rivalry with Iran's undeveloped deposits.
Cross-referencing a 25-person interview survey with the latest experiments shows AI has begun automating parts of the research pipeline on narrow tasks, but the recursive property—where successor models chain improvements upon improvements—remains unproven, and further verification conditions remain.
