Using a burrito analogy to explain how genetic material is densely packed, a new text- and visual-based guide takes readers on a journey through the inner workings of a living cell. The piece highlights the mind-boggling scale of microscopic biology, noting that a bacterium's genome would be nearly 1,000 times longer than its host cell if uncoiled into a straight thread.

Meta and its subcontractor are disputing the reasons behind the sudden layoff of over 1,000 Kenya-based content moderators. The workers were reportedly dismissed after reviewing highly explicit footage from Meta's smart glasses, including videos of users having sex. The two companies currently disagree on the exact cause of these mass redundancies.

The Church Rock uranium mill spill released 1.36 tons of uranium and radioactive contaminants into the Puerco River, severely contaminating the water supply used by the Navajo Nation. The disaster received significantly less media coverage and federal assistance than Three Mile Island, a disparity readers attribute to its rural location and the marginalization of the affected Native American community.
