Researchers have developed a groundbreaking microscopy method that enables detailed three-dimensional (3D) RNA analysis at cellular resolution in whole intact mouse brains. The new method, called TRISCO, has the potential to transform our understanding of brain function, both in normal conditions and in disease, according to the new study.

Historical policies shaping educational attainment have enduring benefits for later life memory and risk of dementia, according to a new study. The study compared the differences in years of education based on variations in state schooling mandates with cognitive performance outcomes in residents decades later.

A new animal study shows that males and females have profoundly different sleep patterns. The findings shed light on what may drive differences in humans and have broad implications for preclinical research that, for decades, has focused primarily on males.

Salk scientists have tracked the flow of trans fats using mouse models to describe the molecular mechanisms that cause trans fats to promote atherosclerotic cardiovascular disease (ASCVD), explaining how industrially produced trans-unsaturated fatty acids in our food significantly promote ASCVD and encouraging lawmakers to impose regulations on the use of these fats in food. This new insight into the flow of fats through the body points to new therapeutic targets for mitigating diseases like ASCVD, non-alcoholic fatty liver disease, obesity, diabetes, peripheral neuropathy, and neurodegeneration.

Experts have identified five elements of a brain-based condition that has emerged as a leading cause of vision impairment starting in childhood in the United States and other industrialized nations. Known as cerebral (or cortical) visual impairment (CVI), some estimates suggest that at least 3% of primary school children exhibit CVI-related visual problems, which vary, but may include difficulty visually searching for an object or person or understanding a scene involving complex motion.

The Wistar Institute and the University of Buea in Cameroon has uncovered the mechanisms for a medicinal plant with anti-HIV potential in Croton oligandrus Pierre & Hutch, a species of African tree that has been used in traditional healing in Cameroon to treat a variety of diseases and conditions including cancers and diabetes.

New research found confined and isolating environments changed the way people smelled and responded emotionally to certain food aromas. The team in this study compared 44 people's emotional responses and perception of eight food aromas in two environmental scenarios: sitting in reclined chairs that mimic astronauts' posture in microgravity; and then in the confined setting of the International Space Station (ISS), which was simulated for participants with virtual reality goggles. The research builds on previous work by the team and aims to help explain why astronauts report meals taste different in space and struggle to eat their normal nutritional intake over long missions, which has been reported in the news recently.
