What inspires you?
Melissa Harris-Lacewell is Associate Professor of Politics and African American Studies at Princeton University. She is the author of the award-winning book, Barbershops, Bibles, and BET: Everyday Talk and Black Political Thought, (Princeton 2004). And she is currently at work on a new book: Sister Citizen: A Text For Colored Girls Who've Considered Politics When Being Strong Wasn't Enough. Her academic research is inspired by a desire to investigate the challenges facing contemporary black Americans and to better understand the multiple, creative ways that African Americans respond to these challenges.
Her academic research has been published in scholarly journals and edited volumes and her interests include the study of African American political thought, black religious ideas and practice, and social and clinical psychology. Professor Harris-Lacewell's creative and dynamic teaching is also motivated by the practical political and racial issues of our time. For example, her course entitled Disaster, Race and American Politics explored the multiple political meanings of Hurricane Katrina. Professor Harris-Lacewell has taught students from grade school to graduate school and has been recognized for her commitment to the classroom as a site of democratic deliberation on race.
Question: What inspires you to do what you do?
Harris-Lacewell: I couldn’t do anything else. The truth is I’m in a certain way very lazy. I’m not particularly capable of doing work that I don’t find interesting, so I do what I find engages my mind and my ideas. But part of it is I really, really like Black people. I like us when we’re making bad decisions. I like us when we’re listening to misogynist music. I like us when we’re paying our bills on time and we’re not. I like us when we get married and have these beautiful ceremonies and jump over brooms. And I also like us when we’re bold and brave enough to raise children on our own. I like the men who write to me from prison and, you know, use all their jailhouse lingo and tell me about the political world. I also like the, you know, little conservative girls who sit in my class and argue with me sort of the Black conservative line. I’m engaged by us. I’m fascinated by us. I’m always trying to figure out what would make life for Black people as equal, as democratic, as real, and as possible for the full capacity of human fulfillment as it is for other people. I think that Black people are the American promise. I believe that it is our struggle around questions of race which makes our country great; that if we did not have those struggles; that if we did not fight to figure out how to be inclusive, and democratic, and deliberative across racial inequality, then we would never get to be a better country. And so I just wanna be a part of that because I actually think it’s at the center of what we are.

Duke University researchers might have solved a half-century old problem.
- The blend of three polymers provides enough flexibility and durability to mimic the knee.
- The next step is to test this hydrogel in sheep; human use can take at least three years.

Their <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/adfm.202003451" target="_blank">new paper</a>, published in the journal,<em> Advanced Functional Materials</em>, details this exciting evolution of this frustrating joint.<br></p><p>Researchers have sought materials strong and versatile enough to repair a knee since at least the seventies. This new hydrogel, comprised of three polymers, might be it. When two of the polymers are stretched, a third keeps the entire structure intact. When pulled 100,000 times, the cartilage held up as well as materials used in bone implants. The team also rubbed the hydrogel against natural cartilage a million times and found it to be as wear-resistant as the real thing. </p><p>The hydrogel has the appearance of Jell-O and is comprised of 60 percent water. Co-author, Feichen Yang, <a href="https://today.duke.edu/2020/06/lab-first-cartilage-mimicking-gel-strong-enough-knees" target="_blank">says</a> this network of polymers is particularly durable: "Only this combination of all three components is both flexible and stiff and therefore strong." </p><p> As with any new material, a lot of testing must be conducted. They don't foresee this hydrogel being implanted into human bodies for at least three years. The next step is to test it out in sheep. </p><p>Still, this is an exciting step forward in the rehabilitation of one of our trickiest joints. Given the potential reward, the wait is worth it. </p><p><span></span>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

What would it be like to experience the 4th dimension?
- 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
- Early treatment is available but there's been no way to tell who needs it.
- Using clinical data already being collected, machine learning can identify who's at risk.
