Most elementary school-aged children have a surprising cognitive ability: they can detect—nearly as well as adults—when someone treats people from one social group differently than another. The study, "Children's and adults' detection of social biases," published in Child Development, demonstrates children's emerging capacity to recognize and reason about social bias.

Is consciousness something the brain produces, or is it woven into the fabric of reality itself? Renowned neuroscientist Christof Koch is challenging long-held scientific assumptions by confronting the “hard problem” of consciousness — why and how subjective experience exists at all. He highlights growing tensions between neuroscience, physics, and unexplained phenomena like near-death experiences and sudden moments of clarity before death.

University of Mississippi research offers hope that cancer drug therapies packaged in 3D-printed carriers could deliver medication directly to tumors while reducing many of the side effects that cancer patients endure. In a study published in Pharmaceutical Research, the Ole Miss team demonstrated that 3D-printed spanlastics—a tiny carrier filled with cancer-fighting drugs—could be implanted directly at the site of a tumor and kill those cells.

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send signals to astrocytes that then activate fullness neurons. This newly discovered pathway could lead to innovative treatments for obesity and eating disorders.
