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...

Low-income communities suffer high rates of parasitic infections in states that neglect sewage systems

By Theresa E. Gildner, Assistant Professor of Biological Anthropology, Arts & Sciences at Washington University in St. Louis Intestinal infections take a heavy toll on impoverished Black communities that have out-of-date sewage systems. These infections often spread through contaminated soil and water and are among the most common diseases worldwide. Approximately one-quarter of the global population is infected with soil-transmitted helminths, intestinal parasitic worms that can cause serious health problems. Additionally, up to 50% of people around the world are infected with Helicobacter pylori, bacteria that live in the stomach and can cause ulcers and cancer. I am a...

Untold Stories: Why enslaved Black people stayed in slaveholding states to help others find freedom

By Viola Franziska Müller, Postdoctoral researcher and lecturer in history, University of Bonn For generations, the Underground Railroad has been the quintessential story of resistance against oppression. Yet, the story is incomplete. What is far less known is that the majority of enslaved people who fled Southern slavery before the 1863 Emancipation Proclamation never crossed the Mason-Dixon line to freedom in the Northern states. Instead, they remained within the slaveholding Southern states. As a scholar of slavery, labor and resistance, I have written about the thousands of enslaved Black people who gravitated to the burgeoning cities and towns of...

The Pentagon Papers: How Daniel Ellsberg’s courage has inspired whistleblowers since the Vietnam War

By Christian Appy, Professor of History, UMass Amherst The history-making whistleblower, Daniel Ellsberg, who by leaking the Pentagon Papers revealed longtime government doubts and deceit about the Vietnam War and inspired acts of retaliation by President Richard Nixon that helped lead to his resignation, died of pancreatic cancer on June 16 at the age of 92. In 1971, when Daniel Ellsberg arrived at a federal court in Boston, a journalist asked if he was concerned about the prospect of going to prison for leaking a 7,000-page top-secret history of the Vietnam War. Ellsberg responded with a question of his...
