Sleep, From Sea to Sense: Jellyfish Reveal Sleep’s Ancient Purpose
Ancient Sleep, Modern Insight Sleep is a universal behavior we associate with humans and many animals, but its roots extend far deeper in the tree of life than most people realize. A groundbreaking study examining jellyfish and sea anemones—creatures among the earliest with nervous systems—suggests that sleep’s core function emerged hundreds of millions of years…

Jellyfish Sleep Study Uncovers Ancient Driver of Sleep
Breakthrough from BIU: Sleep’s Ancient Purpose Revealed Researchers at Bar-Ilan University (BIU) have unveiled a landmark finding about why sleep exists, tracing one of its core functions back to some of the earliest nervous systems on Earth. The study centers on jellyfish and sea anemones—creatures without brains in the traditional sense—yet capable of showcasing a…

BIU Jellyfish Study Reveals Fundamental Driver of Sleep
How Sleep Began: A Deep Dive into Ancient Nervous Systems Sleep is a universal human habit, but its roots run far deeper than human history. A groundbreaking study from Bar-Ilan University (BIU) suggests that the earliest nervous systems, found in jellyfish and sea anemones, reveal a fundamental driver of sleep that predates complex brains. This…

Majority of Alzheimer’s Risk Tied to a Single Gene Variant
Groundbreaking Link Between Gene Variant and Alzheimer’s Risk A new study published in npj Dementia reports a striking association between a specific gene variant and Alzheimer’s disease risk, suggesting that a substantial portion of dementia cases could be influenced by this single genetic factor. While scientists caution that the genetics of Alzheimer’s are complex and…

Five lifestyle factors that could keep your brain eight years younger
Introduction: Your brain, your years New research suggests that everyday choices can influence how young your brain feels and functions. While aging is inevitable, certain lifestyle habits may help preserve cognitive health and potentially make your brain operate as if it were eight years younger. Here are five practical factors backed by recent findings, explained…

Brain Organoids: Modeling Human Brain Development
What Are Brain Organoids and Why They Matter Brain organoids are tiny, lab-grown clusters of neural tissue that resemble certain aspects of the human brain. Each organoid starts from stem cells and, over several months, self-organizes into layered structures that mimic early brain development. Scientists use these miniature brains to study how neural circuits form,…
