A New Theory Describes Ice’s Slippery Behavior

JCP-Persson-icefriction.jpg

In this week’s Journal of Chemical Physics, Bo Persson, a scientist at the Jülich Research Center, discusses his new theory that describes how slippery ice gets when a hard material like a ski slides across it. The theory agrees well with experimental data and could help design better sliding systems, as well as contribute to a fundamental understanding of ice friction that could help explain the movement of glaciers and other natural processes.

A special “suitcase under ultrahigh vacuum conditions,” created by researchers in Japan, will enable researchers to securely transport air-sensitive scientific samples from one advanced laboratory facility to another. The researchers describe their findings in this week's Journal of Vacuum Science and Technology A.

Medical Student Presence Does Not Slow Care in Emergency Departments, Penn Medicine Study Finds

Medical students in Emergency Departments often perform an initial evaluation of stable patients prior to supervising residents or attending physicians, who meanwhile provide care to other patients. Despite some concern over the possible effect to patients, new research shows the presence of medical students in the Emergency Department adds less than five minutes to the average length of a patient’s stay. The findings, from a team of researchers at the Perelman School of Medicine at the University of Pennsylvania, are published in the December 8 Medical Education issue of JAMA.

Climate scientists at NCAR present evidence in a new study that they can predict whether the Arctic sea ice that forms in the winter will grow, shrink, or hold its own over the next several years.

Mayo Clinic Researchers Identify Six Potential Biomarkers for Bipolar I Disorder

Mayo Clinic researchers have discovered a series of proteins that could be diagnostic markers to identify bipolar I disorder. If this discovery sample can be validated through replication these markers may help as a diagnostic tool for psychiatrists treating mood disorders.

Penn Medicine Study Points to Financial and Racial Barriers to Biologic Treatments for Medicare Patients with Moderate to Severe Psoriasis

In the first known study to examine the prevalence and treatment of psoriasis in older Americans, experts from the Perelman School of Medicine at the University of Pennsylvania have found that black patients receiving Medicare are less likely to receive biologic therapies –medications derived from human or animal cells or tissues – for the treatment of moderate to severe psoriasis than white patients.

On a Scale of 1 to 5, How Distracting Is Talking to Your Car? HF/E Researchers Develop a New Framework for Measuring Cognitive Distraction

Distractions while driving can come from visual, physical, and cognitive sources. A special section of the December 2015 Human Factors presents a framework for measuring cognitive distraction, followed by expert commentaries that suggest a way forward for reducing crash risk.

Study: Text Messages That End in a Period Seen as Less Sincere

A team of researchers led by Celia Klin, associate professor of psychology and associate dean at Binghamton University’s Harpur College, recruited 126 Binghamton undergraduates, who read a series of exchanges that appeared either as text messages or as handwritten notes. Based on the participants’ responses, text messages that ended with a period were rated as less sincere than text messages that did not end with a period.

Large Increase in Bed Capacity at North Carolina State Psychiatric Hospital Needed to Reduce Average Patient Wait Time Below One Day

Without increasing community-based psychiatric services, a large number of additional state psychiatric hospital beds would be needed to make a substantial impact on the average wait time of admission for people in crisis in North Carolina, according to a study co-authored by a researcher at RTI Health Solutions, a business unit of RTI International.
