Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing. Stephen Shankland worked at CNET from 1998 to 2024 and wrote ...
I cannot skip a paper that talks about making wormholes. Even if they are fake wormholes. And even if, after reading the paper, I’m not sure that the researchers have made fake wormholes, I simply can ...
A team of researchers from Carnegie Mellon, MIT and Penn State University have developed a different kind of tweezers, one that can move single cells around without damaging them. That's because these ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have ...
3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...

Macroscopic C₅₄₀ model offers new way to study sound wave propagation in topological metamaterials
Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. The technique, described by IMDEA Materials' Dr. Johan ...
Sound can now be structured in three dimensions. Researchers have found a way of generating acoustic holograms, which could improve ultrasound diagnostics and material testing. The holograms can also ...
