MSI PI Tian He, an associate professor in the computer science and engineering department, is among the researchers named a 2014 Resident Fellow of the Institute on the Environment (IonE). IonE Fellows conduct interdisciplinary research that seeks to understand and address environmental problems. Professor He will be working on a project to conduct environmental crowd-sensing data in a Chinese metropolitan area using sensors on taxicabs. This project is related to his group’s research using MSI resources, which uses traffic data from multi-modal online feeds to study and optimize urban transit systems. The huge amount of data now available allows transportation experts to build systems that can deal with changes in the urban environment.

On Wednesday, March 5, from 04:00 - 15:00, MSI staff will perform scheduled maintenance and upgrades to the network and various systems.
During this maintenance period, we will be performing the following updates:
• Networking upgrades will be implemented resulting in a downtime of up to 30 minutes for core MSI systems.
• Cascade will be offline for hardware updates.
• One of Itasca’s login nodes will be unavailable (this shouldn’t impact most users).
• The NX remote desktop service, nx.msi.umn.edu, will be upgraded from 4.0 to version 4.1. At maintenance time, all existing NX sessions will be cancelled. MSI will retire client version 3.5 connections (users should upgrade to the latest NX client).
• Portions of the lab queue will be upgraded.
• One of the MSI login hosts will be unavailable for updates (this shouldn’t impact most users).
• The remaining project shares on the MSI storage resource "buzzard" will be unshared.
Systems status is always available on our Status page.
If you have any questions, please email firstname.lastname@example.org.

A recent story in the University of Minnesota’s Discover series highlights the work of Professor Joseph Metzger, head of the Department of Integrative Biology and Physiology and MSI Principal Investigator. Professor Metzger and his colleagues are developing “patches” - formally known as poloxamers - that can be used to repair leaky cells in the heart. In these cells, the enclosing cell membranes have tears that allow proteins within the cell to escape, thus damaging the ability of the heart to function correctly. This is a condition found in patients with Duchenne muscular dystrophy, or who have had heart attacks or other heart problems.
Professor Metzger uses MSI resources for research into heart cells. Most recently, this research has included creating molecular dynamics simulations of troponin molecules.

A recent paper co-authored by MSI PI Pinar Karaca-Mandic (Health Policy and Management, School of Public Health) has been publicized on various media outlets. The study, “Opioid prescribing by multiple providers in Medicare: Retrospective observational study of insurance claims,” was published last week in the British Medical Journal. Professor Karaca-Mandic wrote the paper along with colleagues at Harvard University and the University of Southern California. The study investigates the number of Medicare recipients who are prescribed painkillers by multiple medical providers. This raises the risk of patients suffering adverse effects from taking too many of these medications.
Professor Karaca-Mandic uses MSI resources for several studies that are analyzing Medicare data.

Assistant Professor Jake Bailey (Earth Sciences) has been awarded an Alfred P. Sloan Research Fellowship. This is a very competitive award that honors early-career U.S. and Canadian researchers. Professor Bailey was given the award in recognition of his work in the field geobiology. He uses MSI resources for this research, which investigates how the activities of microorganisms, especially sulfur bacteria, on the precipitation and dissolution of authigenic minerals. (Authigenic minerals are those that were created where they are found, as opposed to those that were transported to their location by wind or water.) The work involves analysis of single-gene and whole-genome sequence data. More information about the Sloan Fellowship can be found in the College of Science and Engineering’s news release.
