Home > Press > Pore-like proteins designed from scratch: By creating barrel-shaped proteins that embed into lipid membranes, biochemist have expanded the bioengineering toolkit
Abstract:
In a milestone for biomolecular design, a team of scientists has succeeded in creating new proteins that adopt one of the most complex folds known to molecular biology. These designer proteins were shown in the lab to spontaneously fold into their intended structures and embed into lipid membranes. Reported in the journal Science, this research opens the door to the construction of custom nanoscale tools for advanced filtration and DNA sequencing.

Home > Press > Quantum Optimization: Computer scientist Yufei Ding receives NSF Early CAREER Award to advance efforts to improve quantum applications
Abstract:
The key to the incredible speed of a quantum computer lies in its ability to fabricate and manipulate quantum bits, or qubits, typically artificial particles such as ions, superconducting oscillators or protons. Quantum properties allow qubits to form entanglement, a phenomenon that provides far more processing power than the binary bits that drive todays classical computers. Specially designed quantum algorithms, which are lists of operations analogous to a cooking recipe that tell a computer to do something can further speed up calculations to accelerate scientific advances.

Home > Press > Conductive nature in crystal structures revealed at magnification of 10 million times: University of Minnesota study opens up possibilities for new transparent materials that conduct electricity
University of Minnesota Professor K. Andre Mkhoyan and his team used analytical scanning transmission electron microscopy (STEM), which combines imaging with spectroscopy, to observe metallic properties in the perovskite crystal barium stannate (BaSnO3). The atomic-resolution STEM image, with a BaSnO3 crystal structure (on the left), shows an irregular arrangement of atoms identified as the metallic line defect core.

Abstract:
Chemists have developed a nanomaterial that they can trigger to shape shift from flat sheets to tubes and back to sheets again in a controllable fashion. The Journal of the American Chemical Society published a description of the nanomaterial, which was developed at Emory University and holds potential for a range of biomedical applications, from controlled-release drug delivery to tissue engineering.
