A new kind of memory device may finally solve the problem of overheating and battery drain in electronics。 By shrinking components to an extreme scale and redesigning their structure, researchers found a way to reduce energy loss instead of increasing it。 The result is a tiny memory unit that improves as it gets smaller—something once thought impos
In a striking glimpse into extreme physics, scientists have captured the split-second chaos that unfolds when powerful laser flashes blast matter into a superheated plasma。 By combining two cutting-edge lasers, researchers were able to track how copper atoms lose and regain electrons in trillionths of a second, creating and dissolving highly charge
Hello HN,I was away from my computer for two weeks, and after coming back and reading the latest discussions on HN about coding assistants (models, harnesses), I felt very out of the loop。 My normal process would have been to keep reading and figure out the latest and greatest from people's comments, but I wanted to try and automate this process。Ba

A centuries-old vision of a mechanical volcano has finally erupted into reality, as two University of Melbourne engineering students recreated a design first imagined in 1775 by volcanology enthusiast Sir William Hamilton。 Drawing from an 18th-century watercolor and a preserved sketch, they used modern tools like LED lighting and electronic systems
Deep in a dried-up riverbed in Brazil, scientists uncovered a bizarre prehistoric mystery—twisted jawbones from a strange, long-lost animal unlike anything seen before。 Dating back 275 million years, this creature, named Tanyka amnicola, belonged to an ancient lineage that should have already faded away, making it a kind of “living fossil” of its t
