Professors at University of Illinois call out AI-generated student apologies

In a University of Illinois introductory data science course, professors discovered widespread cheating on attendance checks and received AI-generated apologies from students. The incident, involving over 1,000 students, highlights tensions in higher education amid AI use. Instructors addressed the class on October 17, treating it as a life lesson without disciplinary action.

Twin black hole mergers test Einstein's general relativity

Two black hole collisions detected in late 2024 have provided unprecedented tests of Einstein's general theory of relativity. The events, captured by the LIGO-Virgo-KAGRA Collaboration, revealed unusual spins and possible second-generation black holes. These detections confirm theoretical predictions with high precision and probe for new particles.

Scientists make germanium superconducting for the first time

October 30, 2025 Theo Klein

Researchers have achieved superconductivity in germanium, a common semiconductor, by precisely doping it with gallium atoms. This breakthrough, detailed in a new study, could enable more efficient quantum devices and cryogenic electronics. The material conducts electricity with zero resistance at 3.5 Kelvin.

Disney+ adds HDR10+ support to over 1,000 Hulu titles

Disney+ has begun streaming select content in the HDR10+ format, starting with over 1,000 titles from its Hulu integration. This move caters to Samsung TV users, as the service previously supported only HDR10 and Dolby Vision. Additional Disney+ content will gain HDR10+ support in the future.

Scientists create laptop tool to simulate universe structure

Researchers at the University of Waterloo have developed Effort.jl, a new tool that allows scientists to simulate the universe's large-scale structure using just a laptop. This innovation reduces computation time from days on supercomputers to hours, enabling faster analysis of vast cosmic datasets. The tool emulates complex models like the Effective Field Theory of Large-Scale Structure (EFTofLSS).

Magnetic gel aids efficient kidney stone removal in pig tests

Researchers at Stanford University have developed a magnetic gel that coats kidney stone fragments, allowing for their removal in bulk using a magnetic wire. Tested successfully in pigs, the technique aims to reduce tissue damage and the need for repeated surgeries compared to standard methods. Experts praise it as a promising alternative to current procedures.
