Researchers at the Massachusetts Institute of Technology (MIT) have developed an ultra-efficient computer chip that could help tiny robots and lightweight devices create detailed 3D maps of their surroundings while using very little energy. The new chip could allow small drones to fly through narrow spaces, such as air-conditioning ducts or industrial pipelines, to inspect […]

Chronic dietary cholesterol activates Ral GTPases, which promote LDLR internalization and lysosomal degradation through RalBP1–REPS1 and CTSA, thereby reducing cholesterol clearance, whereas CTSA inhibition restores LDLR function and may offer a therapeutic strategy for cardiovascular disease.
