Bayard Rustin: The often-forgotten civil rights activist and man of unwavering compassion

By Jerald Podair, Professor of History, Lawrence University As I began writing “Bayard Rustin: American Dreamer,” my biography of the 20th-century radical leader and activist, one of my colleagues cautioned me not to “fall in love.” This, of course, is good advice for any biographer, and I tried to follow it. But it was not easy, because Bayard Rustin was America’s signature radical voice during the 20th century, and yes, I believe those voices includes that of the Rev. Martin Luther King Jr., whom Rustin trained and mentored. His vision of nonviolence was breathtakingly broad. He was a civil...

A biological hot spot: How the Atlantic Sargassum Belt is inundating coastlines with brown seaweed

By Stephen P. Leatherman, Professor of Coastal Science, Florida International University An unwelcome visitor is headed for Florida and the Caribbean: huge floating mats of sargassum, or free-floating brown seaweed. Nearly every year since 2011, sargassum has inundated Caribbean, Gulf of Mexico and Florida coastlines in warm months, peaking in June and July. This brown tide rots on the beach, driving away tourists, harming local fishing industries and requiring costly cleanups. According to scientists who monitor the formation of sargassum in the Atlantic Ocean, 2023 could produce the largest bloom ever recorded. That’s bad news for destinations like Miami...

Geostrategic Corruption: How China uses economic power to exert its influence in Latin America

By Eduardo Gamarra, Professor of Politics and International Relations, Florida International University; and Valeriia Popova, Professor of Politics and International Relations, Florida International University Corruption has long been a scourge in parts of Latin America. Traditionally, it has funneled down domestic routes, with local politicians, business interests and drug lords benefiting from graft and dodgy dealings. Indeed, a 2022 report from Transparency International found that 27 out of 30 countries in Latin America and the Caribbean have shown stagnant corruption levels with no improvement in recent years. But over the last two decades, a new form of corruption has...

Drone Swarm: Why more unmanned aerial vehicles are filling the skies over Ukraine

By Tara Sonenshine, Edward R. Murrow Professor of Practice in Public Diplomacy, Tufts University Loud explosions rock the evening sky. Streaks of light appear like comets. Missiles rain down. Below, people scramble for cover. The injured are taken on stretchers. That is daily life in Ukraine, where pilotless vehicles known as drones litter the sky in an endless video game-like war with Russia. Both Russia and Ukraine are using drones in this war to remotely locate targets and drop bombs, among other purposes. Today, drones are used in various other conflicts, but are also used to deliver packages, track...

Evading algorithmic detection: How “algospeak” became the newest version of linguistic subterfuge

By Roger J. Kreuz, Associate Dean and Professor of Psychology, University of Memphis A linguistic arms race is raging online, and it is not clear who is winning. On one side are social networks like Facebook, Instagram and TikTok. These sites have become better and better at identifying and removing language and content that violates their community standards. Social media users are on the other side, and they’ve come up with coded terminology designed to evade algorithmic detection. These expressions are collectively referred to as “algospeak.” New terms like these are just the latest development in the history of...

Antibiotic tolerance: Looming behind a growing resistance to some bacteria is another infection crisis

By Megan Keller, Ph.D. Candidate in Microbiology, Cornell University Have you ever had a nasty infection that just won’t seem to go away? Or a runny nose that keeps coming back? You may have been dealing with a bacterium that is tolerant of, though not yet resistant to, antibiotics. Antibiotic resistance is a huge problem, contributing to nearly 1.27 million deaths worldwide in 2019. But antibiotic tolerance is a covert threat that researchers have only recently begun to explore. Antibiotic tolerance happens when a bacterium manages to survive for a long time after being exposed to an antibiotic. While...
