Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that’s thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, [...]
Nanorobots have been successfully programmed to shrink tumors by cutting off their blood supply. This major advancement came from Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences. The demonstration of the technology, the first-of-its-kind study in mammals, used breast [...]
An autonomous molecular machine, made of a single strand of DNA, that can autonomously “walk” around a surface, pick up certain molecules and drop them off in designated locations has been developed by scientists at California Institute of Technology. Lulu Qian, assistant professor of bioengineering, explains: “Just like electromechanical robots are sent off to faraway [...]
A light foam created from two-dimensional sheets of hexagonal boron nitride by materials scientists at Rice University absorbs carbon dioxide. They discovered freeze-drying hexagonal-boron nitride (h-BN) transformed it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix turned it into a far more robust and [...]
An added detector on an electron microscope can aid in determining which molecules are found in which parts of a cell, scientists at the UMCG and Delft University of Technology report. Ben Giepmans, the team leader from Groningen, explains: “This detector enables us to assign a colour to molecules in a cell. Multicolour electron microscopes [...]
