A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs。 By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of traditional designs。 The prototype achieved impressive efficiency and delivered much more power than pr
The brain’s memory center may begin life more like a crowded web than an empty canvas。 Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time。 This pruning process creates a faster, more efficient system for linking experiences and forming mem
New experiments suggest that freezing and thawing on early Earth may have helped primitive cell-like structures grow and evolve。 Tiny lipid bubbles behaved very differently depending on their membrane makeup—some fused into larger compartments and captured DNA more efficiently。 These fusion events could have mixed key molecules, setting the stage f
A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient。 Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time。 Unlike conventional chips that waste energy moving data back and forth, this
Perovskite solar cells shouldn’t work as well as they do—but they do。 Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently。 Using a novel imaging method, they revealed hidden structures acting like charge “highways
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
A major discovery is reshaping how scientists think about catalysts。 Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface。 This reveals that the bulk material can actively participate in reactions, opening a new frontier in catalyst design
