At several archaeological sites in southern Africa, hundreds of highly unusual fragments of ostrich eggs have been found. Dating back more than 60,000 years, the shells were engraved by groups of Homo ...

A pore smaller than one nanometer reads peptide sequences amino acid by amino acid, pinpointing single-site Alzheimer's ...

In chemistry, molecules with a "flat" geometry are often stable enough to support a wide range of reactions. But in the quantum world, that's not technically true.

Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group of proteins that shepherds electrons forward, passing them along like a ...

Microelectromechanical systems (MEMS) electrothermal actuators are widely used in applications ranging from micro-optics and microfluidics to nanomaterial testing, thanks to their compact size and ...

Researchers decipher how elephant trunk hairs enable exceptional tactile senses through material intelligence.

Abstract: High-frequency wideband Hall effect sensors can measure currents in power electronics that operate at higher frequencies (in the Megahertz range). We experimentally investigated the ...

Abstract: Characterization of the profile and thickness of barrier layers in cylindrical vias by cross-sectional transmission electron microscopy (TEM) is crucial for understanding the behavior of Cu ...
