Assessment tool LLMentor supports lecturers in providing feedback on academic texts
Academic writing is one of the skills that students find most difficult to learn on the side. Particularly in bachelor's programs, precise and specific feedback is needed to turn initial drafts into robust exposés for final theses and peer reviews—feedback from fellow
Coral proxy data reveals century-long slowdown of South China Sea throughflow under global warming
The South China Sea Throughflow (SCSTF) serves as a critical oceanic conveyor belt for heat and freshwater, mediating water exchanges between the South China Sea (SCS) and the Pacific and Indian oceans while regulating key processes such as heat and salt budgets, eddy
Political polarization can spur CO₂ emissions and stymie climate action
In recent years, studies and media reports have blamed growing partisan hostility in the U.S. for shattered marriages, broken families, ruined holiday dinners, and increased stress. New CU Boulder research suggests it may have an even broader impact, hindering democracies'
Using moon dirt with 3D printing to build future lunar colonies
Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the
A lost moon may have created Titan and Saturn’s rings
