The curse of rarity—the rarity of safety-critical events in high-dimensional variable spaces—presents significant challenges in ensuring the safety of autonomous vehicles using deep learning. Looking at it from distinct perspectives, the authors identify three potential approaches for addressing the issue.
The planum temporale is a key structure in the human language network. Here the authors show that planum temporale asymmetry at birth in baboons predicts the development of communicative right-hand use, which suggests some common features in the wiring of communicative properties between species.
Chiral amides are important structure in many natural products and pharmaceuticals, yet their efficient synthesis from simple amide feedstock remains challenge due to its weak Lewis basicity. Here, the authors report the enantioselective synthesis of chiral amides by N-alkylation of primary amides via Rh-catalyzed carbene N–H insertion reaction.
How serine synthesis is regulated in cancer remains to be further explored. Here the authors identify FBXO7, an E3 ubiquitin ligase, inhibits serine synthesis in hepatocellular carcinoma by promoting ubiquitination and degradation of PRMT1 methyltransferase.
In2O3/Nb2O5 S-scheme heterojunctions fabricated via a one-step electrospinning technique facilitate contact between two phases, fostering ultrafast interfacial electron transfer to prolong lifetimes and improve CO2 photoreduction performance.
The authors show that dipolar condensates are prevalent in bosonic systems due to a self-proximity effect. Furthermore, they propose a new type of Josephson effect called dipolar Josephson effect, where a supercurrent of dipoles happens in the absence of particle flow.
Using high-resolution ex vivo MRI and serial histology, Ravikumar et al. characterise 3D tau spread across histologically defined medial temporal lobe subregions thus providing a postmortem reference for in vivo studies on early Alzheimer’s disease.
Phosphorescence resonance energy transfer systems have potential in light-harvesting and bioimaging, but host-guest systems are rarely explored. Here, the authors report the development of a macrocyclic host-guest system for targeted cell imaging.
The Stevens rearrangements are a fundamental and powerful tool in the synthetic organic chemistry repertoire, but these transformations are known to be limited in their tolerance for some common functional groups. Here, the authors present a methodology that uses a difluorocarbene unit to induce a Stevens rearrangement, which enables smooth inclusion of allylic and propargyl moieties in the transformation.
Powdery mildew is a devastating disease that affects global wheat production. Here, the authors report the cloning of the Aegilops searsii-derived powdery mildew resistance gene Pm57 that encodes a tandem kinase protein.
Understanding the decentralized self-organization in animal groups helps design swarm robotics, yet the underlying mechanism remains elusive. Xiao et al. analyze collective motions of three large bird-flocking datasets and translate their findings to guide evacuation of a swarm of miniature robots in confinement.
Integrating sensing and actuation capabilities in soft robots is crucial for advancements in medical diagnostics and targeted therapies. Zhang et al. developed bio-inspired sensory robots with multifunctionality for minimally invasive medical procedures.
