A steady diet of high-fat foods leads to reduced pleasure in eating, likely contributing to obesity. UC Berkeley scientists have discovered why, opening up new possibilities for treating obesity — not by fighting desire, but by restoring desire in a healthier way.

(A) Schematic sketch for illustrating the implementation of the memristive network–based RC system for rover control through processing time-sequential sensory signals. Here, voltage-based analog sensory signals carrying spatiotemporal information components are input to the memristive reservoir. These input signals are differentiated and nonlinearly mapped to a high-dimensional data space based on the temporal contexts of the input sensory signals and are quantitatively represented by the reservoir state vector X(t), which is constructed from the voltage readings at multiple neuron terminals. Afterward, the state vector is multiplied by a pretrained weight matrix W(t) to export the output signals Y(t) for controlling the testing rover. (B to D) Training data acquisition for emulating PID control of a robot rover for performing target-tracking navigation: (B) snapshot captured from the training video, showing the PID-controlled rover tracing after a red-moving target (the inset view is a snapshot from the ESP32-based internet-of-things (IoT) camera on the rover); (C) exemplary target coordinate data plotted as the function of time points; (D) exemplary motor signal data generated by a digital PID controller, plotted as the function of time points.

WashU Medicine researcher Kanta Horie, PhD, places a sample in a mass spectrometer that measures protein levels in blood plasma and other fluids. Horie co-led the development of a blood test for Alzheimer’s disease that diagnoses and stages the disease by using mass spectrometry to measure the level of a protein called MTBR-tau243.
