What’s Inside A Sudden, Second Chance At A Climate Bill Last week, climate activists received a surprise gift from Democratic Senators Chuck Schumer and Joe Manchin. It turns out they had been in secret negotiations to put out a spending package that might tackle some of the same climate mitigation projects as last year’s failed Build Back Better initiative. The $369 billion dollars for climate mitigation in the Inflation Reduction Act covers tax credits for renewable energy, methane leak reduction, and the largest environmental justice investment in history. But will it pass before Congress goes on recess? Ira talks to University of California-Santa Barbara political scientist Leah Stokes, who helped advise Senate Democrats during the bill’s crafting, about what the bill might do, and some of the politics shaping climate action.   Engineering and Infrastructure In A Collapsing Climate Roads buckling. Power grids flickering. Roads washing out and basements flooding. Climate change brings new hazards for both human health and the infrastructure that keeps our communities functioning. So how do we build for the conditions that are coming–and in many ways already here? Arizona State University engineer Mikhail Chester talks to Ira about the physical alterations we’ll need and, perhaps more importantly, the way the process of building must change too. Plus why building things to fail—but with less deadly consequences—may be necessary in an uncertain future.   A Teen Inventor Builds A Fingerprint Scanner for Gender Equity The World Bank estimates that around one billion people worldwide don’t have official proof of identity. Without legal identity verification, opening bank accounts, voting, and even buying a cell phone is challenging or even impossible. This issue disproportionately affects women—around half the women in low-income countries do not have proof of identity, which limits their independence and the resources they are able to access. Looking for a solution, 16-year-old Elizabeth Nyamwange invented Etana—an affordable fingerprint scanner that could provide women with a form of digital identity. Her project to close the gender identification gap earned her first place in HP’s Girls Save the World challenge. Ira speaks with Nyamwange, based in Byron, Illinois, about her innovation.   Remembering Nichelle Nichols, Star Trek’s Pioneering Lieutenant Uhura Actress Nichelle Nichols died this week at the age of 89. She was known to people throughout the galaxy for her role as Lieutenant Nyota Uhura, the communications officer on the Starship Enterprise. Her casting as a Black woman in a highly skilled, technical position on a major television program in 1966 was crucial representation—and helped many viewers see science and technology careers as something within their grasp as well. When Nichols considered leaving Star Trek to return to Broadway, a meeting with “her biggest fan”—the Rev. Dr. Martin Luther King, Jr—helped convince her to stay on to contribute to the civil rights movement. Later, Nichols became an ambassador for NASA, working to help recruit people to the space shuttle program, especially women and minorities. In this remembrance, astronaut Leland Melvin helps tell her story, and Tarika Barrett, CEO of the STEM organization Girls Who Code, talks about the importance of role models and representation.
