Professor of Physics Neil Johnson led a team of researchers in developing a mapping model, the first of its kind, to track how online hate clusters thrive. Online hate spreads globally through self-organized, scalable clusters that interconnect to form resilient networks across multiple social media platforms, countries and languages. Published in the journal Nature, the team’s project seeks to understand how hate evolves online by mapping how clusters spread their narratives and attract new recruits. The mapping model could help social media platforms and law enforcement in the battle against hate online.
The Institute for Data, Democracy, and Politics (IDDP), a newly created GW research platform supported by a $5 million investment from the John S. and James L. Knight Foundation, will fight the rise of distorted and misleading information online. With a team of researchers spanning political communication, journalism, physics, international affairs, computer science and engineering, IDDP will work to educate national policymakers and journalists on strategies to grapple with the threat to democracy posed by digital propaganda and deception. IDDP is supported by a $5 million investment from the John S. and James L. Knight Foundation.
Associate Professor of Anthropology David Braun joined an archaeological team in Ethiopia that discovered the oldest evidence of stone tool production, dating back more than 2.58 million years. The excavation took several years before the researchers exposed a layer of animal bones and hundreds of pieces of chipped stone representing the earliest evidence of our direct ancestors making and using stone knives.
Assistant Professor of Biology Keryn Gedan co-authored new research that highlights the growing recognition that sea-level rise will mostly impact rural land—much of which is privately owned—complicating the complex tradeoffs between the value of different land uses. Published in the journal Nature Climate Change, their work is the first to synthesize the growing number of studies of land conversion driven by sea-level rise.
Detailed Early Observations of a Nearby Supernova and Associated Jet Cocoon Provide New Insights about Gamma-ray Bursts
Professor of Astrophysics Chryssa Kouveliotou and an international team of researchers provided new insights into Gamma-ray bursts (GRBs), the most powerful explosions in the cosmos, and their relations to supernova. GRB explosions are so massive that they should always produce visible supernovae. But some supernova do not have associated GRBs. The global research group observed a hot cocoon around the jets of matter that serves as the missing link connecting supernovae and GRBs.
