Jan 17th 2025, 17:13

Cultural traits -- the information, beliefs, behaviors, customs, and practices that shape the character of a population -- are influenced by conformity, the tendency to align with others, or anti-conformity, the choice to deliberately diverge. A new way to model this dynamic interplay could ultimately help explain societal phenomena like political polarization, cultural trends, and the spread of misinformation.

Jan 17th 2025, 12:34

A new study has found older-looking brains in adults with sickle cell disease, helping to explain the cognitive challenges experienced by such individuals. A brain image from a healthy individual (left) shows a larger brain with more white matter compared with a brain image from a patient with sickle cell disease (right). Healthy individuals experiencing economic deprivation also had more-aged appearing brains.

Jan 17th 2025, 12:34

Neuroscientists have identified that the receptor IL-1R1 plays a critical role in enabling neurons to directly communicate with the immune system. The new study provides the most detailed mapping of neuronal IL-1R1 (nIL-1R1) expression in the mouse brain, clarifying prior inconsistencies. Researchers were able to tag neuronal populations that express nIL-1R1 using a clever cell tagging approach, offering new insights into the functional roles of this receptor in the central nervous system (CNS).

Jan 17th 2025, 11:22

Subtle changes in the brain, detectable through advanced imaging, blood and spinal fluid analysis, happen approximately twenty years before a clinical motor diagnosis in people with Huntington's disease, finds a new study.

Jan 17th 2025, 11:22

Cutting-edge fluorescent cholesterol probes now enable scientists to visualize cholesterol movement and distribution in live cells with unprecedented detail. By combining computer simulations with live-cell imaging, researchers have uncovered how different probe designs influence cholesterol probe behavior. These probes could reveal how cholesterol imbalances drive Alzheimer's and other neurodegenerative disorders, aiding drug development to modulate lipid activity and potentially offering new treatments or prevention strategies.
