University of Delaware engineers have shown that magnetic waves called magnons can create electric signals, bridging two key forces in computing. Their work points toward chips that operate faster and more efficiently by eliminating wasted…
An octopus camouflages itself with the seafloor. Credit: Charlotte Seid Using robotic evolution, UC San Diego scientists trained bacteria to produce more of the pigment that powers octopus camouflage. Genetic analysis revealed key mutations that…
A new ultra-flat lens challenges the limits of modern optics, capturing sharp color images once thought impossible. This breakthrough hints at a future where cameras are lighter, smaller, and smarter than ever before. Credit: Shutterstock…
An international team of mathematicians has developed a new predictive method called the Maximum Agreement Linear Predictor (MALP). Unlike traditional techniques that focus only on minimizing average errors, MALP optimizes the Concordance Correlation Coefficient to…

Illustration of a fiber membrane removing heat from an electronic chip through evaporation. Credit: Tianshi Feng Engineers have developed a passive evaporative cooling membrane that dramatically improves heat removal for electronics and data centers Engineers…
Researchers from the University of Colorado Boulder and NREL have uncovered a hidden weakness in perovskite solar cells that could explain why these promising materials fail under stress. By visualizing what happens deep inside the…
Josephson junction structures—quantum devices made of two superconductors and a thin non-superconducting barrier—using different forms of germanium (Ge): super-Ge (in gold), semiconducting Ge (in blue), and super-Ge on wafer-level scale. Millions of Josephson junction pixels…
An integrated spiking artificial neuron, with rich neuron functionality, single-transistor footprints, and low energy consumption for neuromorphic computing systems, can be created by stacking one diffusive memristor and one resistor on top of a transistor….
