New Insight into Genetic Disease Variability

Summary: New research reveals that certain cells inactivate one parent’s copy of a gene, leading to a bias in gene activity that may explain why some individuals with disease-causing mutations…

How Altered States of Consciousness Change Time Perception

Summary: Time perception varies depending on context, often slowing in emergencies or unfamiliar settings and speeding up during absorption or as we age. Time expansion experiences (Tees) occur when seconds…

Poor Sleep Linked to Difficulty Controlling Unwanted Thoughts

Summary: Sleep deprivation impairs brain regions responsible for suppressing unwanted thoughts, contributing to mental health challenges. Functional neuroimaging revealed reduced activation in the prefrontal cortex and increased hippocampal activity in…

Revolutionizing Brain Diagnostics with Light and AI

Summary: A new “molecular lantern” technique allows researchers to monitor molecular changes in the brain non-invasively using a thin light-emitting probe. This innovative tool utilizes Raman spectroscopy to detect chemical…
