Lithium-ion batteries are in almost every electronic device. But how to make them better? To build the next generation of energy storage, researchers are experimenting with the chemistry and structure of batteries, North Carolina State University’s Veronica Augustyn explains. That includes making new materials and looking deep inside batteries to see what’s happening at the atomic level.
Black women make up 25 percent of Brazil’s population – but just about 1 percent of its congressional representatives. That may change on Sunday, thanks to a record number of black women who are on the ballot in Brazil’s general election. The 1,237 Afro-Brazilian women running for public office is a reaction to the alarming rise of sexism and racism in Brazilian politics, writes Kia Lilly Caldwell, a professor of African
diaspora studies at UNC-Chapel Hill.
With newsrooms shrinking and advertising revenue collapsing, it’s tough being a journalist in the 21st century. Texas A&M media historian Randall Sumpter sees a lot of parallels in the Gilded Age of the late 19th century. Back then, media markets were oversaturated, reporter’s pay was being slashed, and owners were convinced that only sensationalism would sell. Sumpter describes the shady practices that Gilded Age reporters
engaged in to scrape by.

Brett Kavanaugh presented himself as a good and reputable man in his recent Senate hearing. But a man's social status and education tell us nothing about whether he's likely to commit sexual assault.
