Research completed for: The brain can unlock true multitasking after intensive training
Key Findings:

Turkeltaub*) used high-resolution fMRI and electroencephalography to show that, after hundreds of practice trials, the neural control of a task migrates from the prefrontal executive areas to sensorimotor circuits and the basal ganglia. Once a skill is ‘proceduralized’, it runs on automatic pilot with minimal demand on the central executive network, freeing cognitive

Episode about New RNA sequencing method reveals hidden layer of immune system control
Research completed for: New RNA sequencing method reveals hidden layer of immune system control
Key Findings:
Scientists at University Medical Center Utrecht, using long-read RNA sequencing, mapped thousands of full-length messenger-RNA molecules inside human immune cells and discovered that, on encountering a pathogen signal, the cells rapidly switch which RNA splice variants they produce. These switches alter protein domains involved in signaling, surface-receptor tuning, and cytokine release—providing an additional, previously underappreciated layer of immune regulation beyond gene-expression levels
