INTRODUCTIONThe cerebellum contributes to many complex brain functions, including motor control, language, and memory. During development, distinct neural cells are generated at cerebellar germinal zones in a spatiotemporally restricted…

Fueling outbreaksThe B.1.1.7 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused fast-spreading outbreaks globally. Intrinsically, this variant has greater transmissibility than its predecessors, but this…

Added value of PCR testing for COVID-19During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, polymerase chain reaction (PCR) tests were generally reported only as binary positive or negative outcomes. However,…

Assays for detecting pathogens are used primarily to diagnose infections. Epidemiologists accumulate results from these tests in time series of case reports to conduct disease surveillance, a cornerstone of public health. During the…

A transient metalVanadium dioxide is known to have a coupled structural and electronic transition that can be accessed through light, thermal, or electrical excitation. Ultrafast optical studies of this insulator-to-metal transition…

Shear selectivityChemical reactions typically proceed by distributing energy statistically among all accessible molecular vibrations. Liu et al. report that external shear forces can sometimes pry open strained carbon rings without…

T cells are thought to integrate information from multiple encounters with antigen-presenting cells to become activated. To explore how the dynamics of T cell receptor signaling influence such a process, Harris et al. developed an optically…

Timing cues epigenomic reprogrammingDifferent temporal dynamics of activation of the transcription factor nuclear factor κB (NF-κB) can influence the inflammatory response of activated macrophages. Cheng et al. report a mechanism by which…

Imaging polariton dynamicsTwo-dimensional (2D) materials can confine light to volumes much shorter than the wavelength, and, together, the long propagation lengths make them attractive materials for developing nanophotonic platforms.…
