And up close, the best star in the universe—our sun—is an orangey sphere of flame . But stars can be

Abstract Online misinformation promotes distrust in science, undermines public health, and may drive civil unrest. During the coronavirus disease 2019 pandemic, Facebook—the world’s largest social media company—began to remove vaccine misinformation as a matter of policy. We evaluated the efficacy of these policies using a comparative interrupted time-series design. We found that Facebook removed

Abstract Normally, stirring is regarded as a technology to disperse the substances in liquid evenly. However, Einstein’s tea leaf paradox (ETLP) describes the phenomenon that tea leaves concentrate in a “doughnut” shape via a secondary flow effect while stirring. Herein, to demonstrate ETLP-induced concentration in nanofluid, we simulated the nanoparticle trajectory under stirring and made a gray

Abstract X-ray photoelectron spectroscopy (XPS) spectra from solid samples are conventionally referenced to the spectrometer Fermi level (FL). While, in the case of metallic samples, alignment of the sample and the spectrometer FLs can be directly verified from the measured Fermi edge position, thus allowing to assess the surface electrical potential, this is not a workable option for insulators.

Abstract As the most promising candidates for the implementation of in-sensor computing, retinomorphic vision sensors can constitute built-in neural networks and directly implement multiply-and-accumulation operations using responsivities as the weights. However, existing retinomorphic vision sensors mainly use a sustained gate bias to maintain the responsivity due to its volatile nature. Here, w

Abstract Cancers feature substantial intratumoral heterogeneity of genetic and phenotypically distinct lineages. Although interactions between coexisting lineages are emerging as a potential contributor to tumor evolution, the extent and nature of these interactions remain largely unknown. We postulated that tumors develop ecological interactions that sustain diversity and facilitate metastasis.

Abstract Translocations producing rearranged versions of the transcription factor double homeobox 4 (DUX4-r) are one of the most frequent causes of B cell acute lymphoblastic leukemia (B-ALL). DUX4-r retains the DNA binding domain of wild-type DUX4 but is truncated on the C-terminal transcription activation domain. The precise mechanism through which DUX4-r causes leukemia is unknown, and no targ
