Everything is a fuse if you run enough current through it. Or at least [JohnsonFarms.us] seems to think so, which has led him to design 3D-printed fuses made from conductive PLA filament. In ...

Smart glasses with augmented reality displays and computer vision sound very useful, but the creep factor is doing them in.

Because there’s no current in the insulating layer, charge is trapped inside that layer, and the classical laws of physics say that voltage should also measure zero. Just as a tennis ball thrown at a ...

▲ 摘要：光谱学作为判定物质结构与化学成分的关键技术，已广泛应用于众多科学领域。传统光谱技术受限于窄缝或光栅结构，必须在光谱分辨率与光学透射率之间进行权衡，因而无法同时实现高灵敏度与高效率测量。研究者提出名为RAFAEL的亚埃级超高通量瞬时光谱技术，该技术基于铌酸锂集成可重构光子器件，成功突破了上述局限。

Incidents of sudden death have repeatedly occurred without any prior medical symptoms to signal its approach or warn of its raid. These incidents, especially among young people, raise the question: ...
