When Treating Brain Aneurysms, Two Isn’t Always Better Than One

Is it better to treat aneurysms with two overlapping flow diverters, or one compressed diverter? A computational study published in the American Journal of Neuroradiology points to the single, compressed diverter provided that it produces a mesh denser than the two overlapped diverters, and that it covers at least half of the aneurysm opening. The ongoing research could eventually help doctors determine the best way to treat patients suffering from aneurysms.

Researchers Flip Script for Li-Ion Electrolytes to Simulate Better Batteries

electrolyte_image_miller.JPG

A team led by the California Institute of Technology’s (Caltech’s) Thomas Miller used the Cray XK7 Titan supercomputer at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) to identify potential electrolyte materials and predict which ones could enhance the performance of lithium-ion batteries. Using Titan, the researchers ran hundreds of simulations—each consisting of thousands of atoms—on possible new electrolytes. The work led them to the identification of new electrolytes with promising properties for lithium-ion conduction.

The Shape of Melting in Two Dimensions

As part of her team’s research into matter’s tendency to self-organize, Sharon Glotzer of the University of Michigan ran a series of hard particle simulations to study melting in two-dimensional (2-D) systems. Specifically, the team explored how particle shape affects the physics of a 2-D solid-to-fluid melting transition.

A paper released December 15 during the American Geophysical Union fall meeting points to new evidence of human influence on extreme weather events. After examining observational and simulated temperature and heat indexes, the research team—which included three scientists from Lawrence Berkeley National Laboratory—concluded that two separate deadly heat waves that occurred in India and Pakistan in the summer of 2015 “were exacerbated by anthropogenic climate change.”

An international collaboration between physicists at the University of Chicago, Argonne National Laboratory, McGill University, and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit. First published online Nov. 28, 2016, in Nature Physics, their experiments on a single electron in a diamond chip could create quantum devices that are less to prone to errors when operated at high speeds.
