Exploring systemic racism as the default explanation for disparities‎

Much of the field of sociology treats systemic racism as its default explanation for racial disparities rather than as an open question that requires further investigation and evidence, according to a recent position paper. The assumptions and moralization surrounding the origins of race-based disparities have undermined the discipline and made it difficult—and professionally costly—to challenge the concept, says author Ilana Redstone, a professor of sociology at the University of Illinois Urbana-Champaign.

Neutrons, rotating black holes, and a galactic PeVatron at the center of the Milky Way‎

Galactic black holes are cosmic mitochondria, powerhouses of the universe. Most of the energy these supermassive black holes produce comes from the material surrounding them: superheated plasma in their accretion disks interacting with tremendous magnetic fields. But there is a more direct way to extract energy from a black hole. It's known as the Penrose process, and a new study asks whether we could discover a signature of this process.

More than half of the Ecuadorian Amazon has been marked for oil drilling, overlapping with Indigenous territories and areas of high biodiversity.

Political orientation and institutional trust emerge as key factors in local wind energy support‎

Why does the expansion of wind energy sometimes meet with local resistance, even though renewable energy generally enjoys broad support? RIFS researcher Jörg Radtke used a representative survey of 6,284 people in North Rhine-Westphalia to investigate which social characteristics are linked to the acceptance of wind energy.

Game simulator shows how math can guide decisions when resources are limited‎

In "Bloons Tower Defense," the goal is to stop balloons from reaching the end of a track by strategically placing towers along the route. These towers vary in cost, range and attack power, and they also take up valuable space. The game becomes increasingly difficult with each round. Where you place a tower therefore determines not only how effective it is now but also which options remain available later in the game.
