    Understanding the cellular mechanisms driving solid tumors’ robust defense system
    A 3D rendering of the tumor microenvironment with cancer cells, T-Cells, nanoparticles, cancer associated fibroblast layer of tumor microenvironment normal cells, molecules, and blood vessels.

    In a collaborative interdisciplinary study, Michael Mitchell of the School of Engineering and Applied Science, Wei Guo of the School of Arts & Sciences, and Drew Weissman of the Perelman School of Medicine show that solid tumors can block drug-delivery mechanisms with a “forcefield-like” effect but certain genetic elements that can effectively “shut down” the forcefield. Their findings hint at new targets for delivering cancer treatments that use the body’s immune system to fight tumors.

    “Understanding the human factors and ethical implications of autonomous systems is just as crucial as the technical components,” says Mangharam. “This holistic approach aims to produce well-rounded engineers capable of addressing the multifaceted challenges of autonomous vehicle technology. Our goal is to equip them with the tools and mindset to tackle the challenges and opportunities of tomorrow.”

    Does heat travel differently in tight spaces?
    Green-tinted image showing thermal plumes in a Hele-Shaw cell, illustrating heat transfer in confined spaces.

    Hugo Ulloa and Daisuke Noto of the School of Arts & Sciences have unearthed findings that address long-standing mysteries in the mechanics of fluids in confined, tight spaces: how their boundaries affect heat as it emanates from one place and dissipates throughout the space. The image above is a lab-scale hydrothermal system modeled utilizing a Hele-Shaw cell of 10 cm tall, 20 cm long and 4 mm gap. The interior of the Hele-Shaw cell is filled with degassed, deionized water heated from the bottom and cooled from above. A green laser sheet crosses the middle plane of the cell to visualize the motions of micro-scale particles seeded on the water, allowing researchers to estimate the fluid velocity and temperature.
