Researchers at The Ohio State University have discovered how to control heat with a magnetic field. An experiment proved that the phonon—the elementary particle that carries heat and sound—has magnetic properties. This artist’s rendering, based on computer simulations, depicts a phonon heating solid material. Atoms of the material, shown in orange, are joined with flexible atomic bonds, shown as springs. The phonon imparts heat by colliding with the center atom, creating a vibration in the springs. The trail of the passing phonon is marked with increased magnetic field intensity, shown in green. The figure in the lower right shows the direction of the applied magnetic field. The researchers found that a sufficiently strong magnetic field can cause phonons to collide with each other and be deflected off-course, which slows the flow of heat through the material.

Researchers at The Ohio State University have discovered that heat can be controlled with a magnetic field. Here, study leader Joseph Heremans, Ohio Eminent Scholar in Nanotechnology, holds the material used in the experiment: a piece of indium antimonide semiconductor shaped into a lopsided tuning fork. The wider arm of the fork (left) measures 4 mm wide, and the narrower one (right) measures 1 mm. The researchers were able to slow the movement of heat through the wider arm of the fork using a magnetic field. Photo by Kevin Fitzsimons, courtesy of The Ohio State University.

Documentary examines racism – March 23. The feature documentary film, I’m Not Racist. . . Am I?, about the next generation and racism, will be shown Monday, March 23 in Mershon Auditorium, 1871 N. High St. The film screening and a discussion with the filmmakers takes place from 5:30 to 7:30 p.m., and a reception precedes it from 4:30 to 5:15 p.m.
In the documentary, 12 New York City teenagers come together during one school year to talk about race and privilege in a series of workshops and in conversations with friends and family members. The event is free and open to the public. SEE: https://artsandsciences.osu.edu/events/film-viewing-im-not-a-racist-am-I.

Lecture explores “Solutions to Political Polarization in America” – March 25. Ohio State’s Democracy Studies Program presents a talk on “Solutions to Political Polarization in America” by Nate Persily, professor of law at Stanford Law School, at 4 p.m. on Wednesday, March 25, in 344 Drinko Hall, 55 W. 12^th Ave. Persily is a nationally recognized constitutional law expert who served as senior research director for the bipartisan Presidential Commission on Election Administration, which was created to address the long lines at the polls and other administrative problems in the 2012 election. The event is free and open to all. SEE: http://artsandsciences.osu.edu/events/solutions-to-political-polarization-in-america.

Events and activities mark Ohio Union’s fifth birthday – March 25 – 29. The Ohio Union, 1739 N. High St., opened five years ago, on March 29, 2010. The Office of Student Life is celebrating the special occasion with a number of events and contests for students in the week leading up to the Ohio Union’s “birthday.” Activities include a tweet-and-go-seek scavenger hunt, a photobooth, musical chairs, building tours and more. CONTACT: Dave Isaacs, 614-292-8424, isaacs.84@osu.edu. SEE: http://ohiounion.osu.edu/articles/Ohio%20Union/id/692

Ohio State University researchers study student LGBTQ population. Ohio State University researchers have undertaken the most robust known study of its kind at a single university to find out what resources and programs lesbian, gay, bisexual, transgender, queer (LGBTQ) and questioning (Q) students need to be successful.
For the study, Exploring Wellbeing to Support Success of LGBTQQ Students at The Ohio State University, researchers engaged nearly 750 students and more than 130 personnel across campuses to ask about what students need to ensure their well-being and academic achievement.
Recommendations resulting from the study address a wide range of areas, such as curriculum; development of LGBTQ-inclusive policies; creation of safe, inclusive spaces; developing programs, events and support for LGBTQ graduate and professional students; and increased LGBTQ visibility and outreach.“While LGBTQ students have become more visible and accepted as part of the diversity spectrum, little research has been done at Ohio State or anywhere in higher education that directly seeks to understand the perceptions, experiences and needs of this marginalized group within its student body,” said Tamara Davis, lead author of the study and an associate professor of social work.

By 2040, the number of seniors in Franklin County is expected to double – and arecently completed report co-authored by Holly Dabelko-Schoeny, associate professor of social work, reveals the current and projected needs of seniors while identifying key opportunities for improving their quality of life. Meeting the Challenges of an Aging Population with Success, commissioned by The Columbus Foundation and the Osteopathic Heritage Foundations, will be instrumental as strategies are developed on how to support a growing aging population. Key findings indicate that improved coordination between the complex web of federal, state, county, and municipal resources would have significant impact on seniors’ health and quality of life. The report also includes an analysis of the most vulnerable seniors in Franklin County identified at the neighborhood level. The research of senior populations was conducted by the College of Social Work and The Kirwan Institute for the Study of Race and Ethnicity.
