  • A sense of space in postrhinal cortex July 11, 2019
    A topographic representation of local space is critical for navigation and spatial memory. In humans, topographic spatial learning relies upon the parahippocampal cortex, damage to which renders patients unable to navigate their surroundings or develop new spatial representations. Stable spatial signals have not yet been observed in its rat homolog, the postrhinal cortex. We recorded […]

  • Enhanced CAR-T cell activity against solid tumors by vaccine boosting through the chimeric receptor July 11, 2019
    Chimeric antigen receptor–T cell (CAR-T) therapy has been effective in the treatment of hematologic malignancies, but it has shown limited efficacy against solid tumors. Here we demonstrate an approach to enhancing CAR-T function in solid tumors by directly vaccine-boosting donor cells through their chimeric receptor in vivo. We designed amphiphile CAR-T ligands (amph-ligands) that, upon […]

  • Posterior parietal cortex plays a causal role in perceptual and categorical decisions July 11, 2019
    Posterior parietal cortex (PPC) activity correlates with monkeys’ decisions during visual discrimination and categorization tasks. However, recent work has questioned whether decision-correlated PPC activity plays a causal role in such decisions. That study focused on PPC’s contribution to motor aspects of decisions (deciding where to move), but not sensory evaluation aspects (deciding what you are […]

  • Strain-programmable fiber-based artificial muscle July 11, 2019
    Artificial muscles may accelerate the development of robotics, haptics, and prosthetics. Although advances in polymer-based actuators have delivered unprecedented strengths, producing these devices at scale with tunable dimensions remains a challenge. We applied a high-throughput iterative fiber-drawing technique to create strain-programmable artificial muscles with dimensions spanning three orders of magnitude. These fiber-based actuators are thermally […]
