Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that past versions required ...
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Materials with magnetic nanostructures have a wide range of potential applications. One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and ...
