Targeting sepsis, the leading cause of ICU deaths, with a nanocarrier-delivered microRNA

ScienceDaily.com: Nanotechnology News - Mon, 12/03/2018 - 20:54
One obstacle to therapeutic use of microRNAs (miRNA), which are in clinical trial for a number of diseases, are ribonucleases, whose job it is to destroy them. Researchers report that an miRNA (miR-126) protective against sepsis can be delivered effectively via a nanocarrier. Almost 67 percent of mice treated with one of the nanocarrier/miR-126 complexes were still alive at seven days vs. just 25 percent of controls.

A new way to see stress -- using supercomputers

ScienceDaily.com: Nanotechnology News - Fri, 11/30/2018 - 20:16
Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. Widely-used atomic stress formulae significantly underestimate stress near stress concentrators such as dislocation core, crack tip, or interface, in a material under deformation. Supercomputers simulate force interactions of Lennard-Jones perfect single crystal of 240,000 atoms. Study findings could help scientists design new materials such as glass or metal that doesn't ice up.
