OSU Announces Spring Commencement Speaker

OSU will welcome CEO of the Gates Foundation, Dr. Sue-Desmond-Hellman for as its Spring Commencement speaker. Over 11,000 students will walk across the stage at this ceremony scheduled Sunday, May 6 at the OSU stadium.

Desmond-Hellman has played many roles–scientist and philanthropist–but in all her roles she has dedicated herself to bettering human lives. As CEO of the Gate’s foundation, she is the leader of their vision of a world where all humans are given the opportunity to be healthy and productive people

Desmond-Hellmann strives to build an organization in which talented and committed people help others thrive, fight diseases that hit the less-fortunate, and empower people.

She was also doing good work before leading the Gates Foundation, she  was the first female chancellor of the University of California, San Francisco, the university in which she completed her clinical training there in the 1980s.

OSU Researches Study Our Ability To Recognize Emotions in Facial Expression

A fascinating new study by researchers at OSU has found that people can correctly identify another person’s feelings with 75% accuracy based only little changes in blood flow color around the nose, eyebrows, cheeks and chin.

The new research allowed scientists to construct computer programs that accurately recognize emotions using the same parameters of blood flow coloration with 90% accuracy. The newly documented research on the connection between the central nervous system and emotion expression in human faces was published in the Proceedings of the National Academy of Sciences.

Researchers see their work being used in the field of AI, hoping that it will allow machine learning programs to recognize and maybe even emulate human emotion–towards this end they are patenting their own algorithms. They have also found a way to commercialize the research through their spin-off company, Online Emotion.


Buckeyes Host Ohio’s Severe Weather Awareness Week

The Ohio State Meteorology Club sponsored the 22nd Annual Severe Weather Symposium last week. The symposium finds meteorologists from all across the country and from many specialties  to give presentations, but also to interact with students interested in the field.

Guest speakers included Cory Mottice, who is a forecaster for the National Weather Service office in Cleveland, Ohio. Another speaker, Jeff Logsdon, is a science and operations officer for the National Weather Service in Northern Indiana. They also invited WTVG Chief Meteorologist Jay Berschback.

While lots of topics were covered, the most discussed  were severe weather issues. These issue included the unusual outbreak of tornadoes in Ohio in 2017 as well as the impact of hurricanes Harvey and Irma.

Mr. Logsdon focused his discussion on two issues. First the very powerful tornado that crossed 39 miles from Indiana to Ohio. He also talked about the historic flooding that ravaged Indiana last year.

OSU Biomedical Engineers 3D Print Replacement Heart Valves

Physicians at The Ohio State University Wexner Medical Center are taking an innovative approach to improve care for patients receiving aortic valve replacements. They’re working alongside biomedical engineers from Ohio State’s College of Engineering, who have developed a way to model and predict potential complications so they can be avoided.

The most common reason the aortic valve needs to be replaced is aortic stenosis, or narrowing of the valve opening. Over decades, the valve leaflets can become stiff from calcification, making it harder to pump blood from the left ventricle into the aorta. There are two options to replace the diseased valve – open heart surgery through a traditional opening of the chest, or a less invasive transcatheter method that deploys a tissue (bioprosthetic) valve through a blood vessel in the leg.

To help decide which approach and which valve is right for each patient, physicians and biomedical engineers at Ohio State do something unique: They create personalized 3D models of the aortic valve and neighboring structures and simulate how the new valve will function. This group meets weekly to decide together what will be best for the patient.

The team, which includes graduate students from biomedical and mechanical engineering, precisely reconstruct a patient’s aorta and 3D print it from the patient’s CT scan using various flexible materials that mimic the real aorta. They load the model into a heart simulator which pumps transparent, simulated blood through the system.
