Study reveals new way to unlock blood-brain barrier, potentially opening doors to treat brain and nerve diseases

Researchers developed an innovative approach -- demonstrated in mouse models and isolated human brain tissue -- to safely and effectively deliver therapeutics into the brain, providing new possibilities for treating a wide range of neurological and psychiatric diseases. The study introduces a first-of-its-kind blood-brain barrier-crossing conjugate (BCC) system, designed to overcome the protective barrier that typically blocks large biomolecules from reaching the central nervous system (CNS).

Exploring factors affecting workers' acquisition of exercise habits using machine learning approaches

Researchers analyzed data from middle-aged workers who had received Specific Health Guidance -- a revolutionary system implemented by the Japanese Ministry of Health, Labor, and Welfare to improve lifestyle habits for individuals with metabolic syndrome and those at presumptive risk of metabolic syndrome. Using machine learning approaches, they explored the factors that affect the acquisition of exercise habits. The results revealed that the most crucial factor that positively impacts the acquisition of exercise habits is 'the higher stages of lifestyle behavior based on the transtheoretical model.'

Confinement may affect how we smell and feel about food

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.

Fermium studied at GSI/FAIR: Researchers investigate nuclear properties of element 100 with laser light

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? Researchers report on experiments to come closer to an answer. They gained insight into the structure of atomic nuclei of fermium (element 100) with different numbers of neutrons. Using forefront laser spectroscopy techniques, they traced the evolution of the nuclear charge radius and found a steady increase as neutrons were added to the nuclei. This indicates that localized nuclear shell effects have a reduced influence on the nuclear charge radius in these heavy nuclei
