However, existing molecular materials lack the ferromagnetic strength required for high-fidelity sensing at clinically relevant tissue depths. Here we introduce a bioresorbable metal-free molecular magnet derived from graphitic carbon nitride, combining metallic-level ferromagnetism with full bioresorbability. De-nitrogenation creates spin centres coupled through a reconstructed π–σ conjugated framework, conferring robust spontaneous magnetization that remains stable under physiological conditions. Integrated with poly(lactic-co-glycolic acid) and silk fibroin, the material forms catheter-deliverable epicardial patches for cardiac tracking and can also be dispersed in injectable hydrogels for organ-scale sensing, including the three-dimensional reconstruction of localized hepatic pathologies. Coupled with a skin-interfaced Hall array, this magnetic sensing architecture provides the continuous, untethered monitoring of multi-organ dynamics, robust against motion artifacts and tissue impedance. In porcine models, it facilitates the continuous assessment of ejection fraction over 4 weeks, followed by benign bioresorption. Benchmarked against standard-of-care echocardiography, this approach delivers clinical-grade trajectories, supporting longitudinal, infrastructure-independent physiological monitoring.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"193 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149218198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to their strong in-plane anisotropy, which enables polarization-controlled optical transitions to distinct non-degenerate valleys, group-IV monochalcogenides have been recently proposed as promising candidates for next-generation valleytronic materials. However, ultrafast non-equilibrium dynamics following the optical preparation of valley-polarized states have received limited attention in these systems. Here, combining time- and angle-resolved extreme-ultraviolet photoemission spectroscopy with time-dependent Boltzmann equation simulations, we investigate ultrafast valley polarization dynamics following polarization-controlled photoexcitation in SnSe. We show that selective excitation to valleys at global conduction minima yields nearly unity and time-independent valley polarization. By contrast, photoexcitation to the other valley channel leads to ultrafast decay and reversal of valley polarization on subpicosecond timescales due to intervalley scattering mediated by strong electron-phonon coupling with an optical phonon mode. Our findings reveal strongly anisotropic and radically different non-equilibrium valley physics than in most common two-dimensional valleytronics materials.</p>","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149137702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By embedding cell-free gene expression within a dense microtubule network, DNA instructions synthesize molecular motors, cross-linkers and transcription factors that continuously generate and regulate active stresses. This experimental platform enables gene-circuit architectures to directly program active-matter dynamics, producing steady, pulsed, arrested and oscillatory mechanical states from genetically encoded biochemical regulation alone. A coarse-grained reaction-mechanics model quantitatively captures these behaviours and shows how gene-circuit parameters, including expression rates, degradation kinetics and regulatory topology, govern the emergence and temporal evolution of active-matter states. Together, these results establish gene circuits as programmable control layers for active matter, providing a general strategy for engineering genetically encoded mechanochemical materials and autonomous active systems.</p>","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149137667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we demonstrate magnetically tunable exciton-polariton condensation in the van der Waals magnet CrSBr. Under photoexcitation, CrSBr microwires embedded in an optical cavity show the hallmarks of polariton condensation. Owing to the strong coupling between the spin order and excitonic correlation, the energy of the condensate can be tuned by up to 10.5 meV by an external magnetic field of 2 T.

Progress has been limited by the lack of large single crystals suitable for neutron spectroscopy. Here we overcome this limitation and map the spin order and excitations of single-crystalline La3Ni2O7. We find single-stripe magnetic order with a finite spin gap, anisotropic in-plane excitations and pronounced bilayer modulation revealing antiferromagnetic interlayer coupling. The dispersion is captured by a bilayer Heisenberg-type model with strong interlayer exchange and competing in-plane couplings. Absolute normalization reveals that, although the spin-wave bandwidth is only about 25% of that in cuprates, the local dynamic susceptibility at comparable energies is enhanced, yielding a comparable total fluctuating moment. These results highlight intense mid-energy spin excitations rooted in substantial electronic correlations, establishing a magnetic framework distinct from cuprates and relevant to superconductivity in nickelates.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"36 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149087803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
