Now imagine sharing the same meal with friends or colleagues: depending on the social context, you may find yourself eating more carefully, adapting your food choices, restraining yourself or competing for portions, and following social norms in conversation and table manners.

Supermassive black holes sit in 'eye of their own storms,' studies find‎

Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists has used data from a recently launched satellite to reveal our clearest look yet into the boiling, seething gas surrounding two supermassive black holes, each located in the center of massive galaxy clusters.

AI systems could identify math anxiety from student inputs and change feedback‎

Math anxiety is a significant challenge for students worldwide. While personalized support is widely recognized as the most effective way to address it, many teachers struggle to deliver this level of support at scale within busy classrooms. New research from Adelaide University shows how artificial intelligence (AI) could help address challenges such as math anxiety by using a student's inputs and identifying signs of anxiety or disengagement during learning.

Warmer Northeast Atlantic waters and heavy fishing leave cod and haddock chasing smaller prey‎

Fish across Britain's seas face ever-smaller meals as warmer seas and commercial fishing squeeze ocean food webs, new research suggests. Research by the University of Essex and the UK Government's Centre for Environment, Fisheries, and Aquaculture Science (Cefas) found strains across warm and highly fished areas of the Northeast Atlantic, leaving predators such as cod, haddock and thorny skate with less energy from every meal.
