When firefighters run into a burning building, they know the dangers associated with their job. But new research suggests firefighters are at risk before they ever leave the firehouse.Using a spectroscopic technique and the St. Andre particle accelerator, Notre Dame professor Graham Peaslee has found alarming amounts of polyfluoroalkyl substances (PFAS) in firefighter gear. These chemicals have been linked to elevated rates of cancer and have also been found in fast-food wrappers, cosmetics, drinking water, carpet and flame retardants. He is now working to test many years of new and used gear to better assess the risks for firefighters.Professor Peaslee’s work in this area has encouraged several companies to reduce or eliminate PFAS, and the EPA and state legislators have also made policy changes. He hopes this new study will make firefighters safer, so they can continue to keep all of us safe.

Marissa Koscielski ’17, ’18 M.S., was in eighth grade when she was told she wouldn’t walk again. A gymnastics accident and spinal mass had left her paralyzed on the left side from the waist down. But she was determined and decided to build her own device to facilitate her rehabilitation. With strings and tape and bits of therapy equipment, Marissa repurposed a walker to help her slowly walk, and then run, once more.The experience taught her there is a gap in the tools and technology available for those rehabilitating from severe injuries, illnesses, and amputations. After completing her undergraduate degree at Notre Dame, she entered the ESTEEM program—a one-year master of science program focused on entrepreneurship and commercialization—and launched Enlighten Mobility, a startup that designs specialized rehab technology. Today, all of the company’s employees are Notre Dame graduates. Enlighten Mobility has since created its first product, a gait trainer largely based on the one Marissa designed for herself. The walker and other upcoming inventions are enabling Marissa to help others walk again.Learn more: https://go.nd.edu/HelpOthersWalkAgain

At the St. Joseph County Cyber Crimes Unit, eight Notre Dame undergraduates raised their right hands to be sworn in as law enforcement officers. They’re the only students in the country with that designation, and with it comes a host of responsibilities.The students are key in researching online activity, creating suspect profiles, executing warrants, and gleaning digital forensics from all confiscated media. They’ve seen cases ranging from drug trafficking to homicides, and have helped local law enforcement lock up perpetrators and set innocent suspects free. While beat cops and detectives are experts on the streets, the students are experts in social media and the Internet. They’ve taken a months-long backlog and reduced it to a matter of hours.While the students have been immensely helpful to the police force in South Bend, they are getting beneficial experience as well. The skills they’re honing are attractive to law enforcement, the FBI, technology firms, and consulting groups, and the internship is helping them stand out to potential employers.Learn more: https://go.nd.edu/UncoverTheEvidence

In a given year, around 60,000 Americans experience advanced heart failure, and many of them need a heart transplant to survive. While 10,000 hearts are donated each year, nearly 7,000 of them are not used. About half are not healthy enough, and though the other half are fully functional, those hearts can’t get to the recipient within the four-hour window recommended for effective transplants.But thanks to a partnership between Notre Dame engineering professor Pinar Zorlutuna and the University of Florida, there may be a way to extend that window to eight hours, which would allow many more donated hearts to reach patients. Professor Zorlutuna has created a novel and ethical way of converting adult blood and skin cells to functioning, beating heart muscle. These heart cells are being used to test an improved preservative solution that lengthens a donated heart’s lifespan. This safe and inexpensive platform has allowed for treatments to be tested without using very precious donated hearts, and initial studies show promise for these solutions.Learn more: https://ntrda.me/FFHumanHeart Learn more about Professor Zorlatuna: https://go.nd.edu/WomenLeadZorlatuna

In the wake of 9/11, Professor Ebrahim Moosa was overcome with frustration at the acts of violence being committed in the name of Islam. A devout Muslim himself, he had also been the target of a terrorist attack for speaking out against extremists.One issue, he realized, was that the curriculum being taught in madrasas, traditional schools of Islam, hadn’t been updated for centuries. It failed to engage with modern science, history, politics, and new research in religion. He thought he could teach some of these subjects to madrasa graduates to illustrate how Islam and modern life could peacefully coexist based on his own experiences. Those lessons, he believed, would be useful for the graduates in their engagement and education of their own communities.Thus, the Madrasas Discourses project was born at Notre Dame with an inaugural group of 55 Indian and Pakistani madrasa leaders. These students take weekly online courses with Professor Moosa and his colleagues and also meet twice annually. Two years later, Moosa claims the project is the most rewarding accomplishment of his life. The participants, too, are highly enthusiastic. Plans to expand the program and welcome students from sub-Saharan Africa are underway.As the Keough School of Global Affairs welcomes people from all nationalities, religions, and traditions to help solve the world’s challenges, Professor Moosa serves as a powerful example of how working collaboratively can make dramatic change.
