Have you ever felt like the world around you isn’t exactly… “real”? Modern physics is starting to suggest something incredible: The universe isn’t made of atoms, energy, or particles. It is made of Information. In this video, we explore the radical “It from Bit” theory and the Holographic Principle. From the mysterious paradoxes of Black Holes and Hawking Radiation to the way quantum entanglement might actually create the fabric of space and time, we dive deep into the mind-bending reality of quantum mechanics. In this video, we cover: Why Stephen Hawking conceded the Black Hole Information Paradox. The Ryu-Takayanagi formula: How entanglement builds geometry. Why 3D space might just be a 2D holographic projection. The “It from Bit” philosophy by John Wheeler. How consciousness relates to Integrated Information Theory (IIT). If reality is just a pattern of qubits in a vast Hilbert space, what does that make us? Join us as we deconstruct the material world and look at the “source code” of the universe. #QuantumPhysics #HolographicUniverse #ItFromBit #TheoreticalPhysics #ScienceDocumentary #SpaceTime #quantuminformation

A new class of Alzheimer’s biomarkers: Why protein shape may beat protein levels
Researchers have identified a new type of blood-based biomarker test for Alzheimer’s disease that measures structural changes in proteins, providing more information on the underlying biology of the disease than standard blood tests. The findings, published in Nature Aging, also provide new insights into how Alzheimer’s disease biology may differ between males and females.
“This work introduces a fundamentally new, blood-based approach to detecting and staging Alzheimer’s disease,” said Dr. Richard Hodes, director of NIH’s National Institute on Aging (NIA). “By revealing protein structural changes associated with genetic risk, symptom severity, and sex differences—features not captured by existing biomarkers—this research could enable earlier diagnosis and more effective clinical trials.”

Foundation AI model uses MRI data to predict multiple brain disorders
Artificial intelligence (AI) systems are computational models that can learn to identify patterns in data, make accurate predictions or generate content (e.g., texts, images, videos or sound recordings). These models can reliably complete various tasks and are now also used to carry out research rooted in different fields.
Over the past few decades, some AI models have proved promising for the early diagnosis and study of specific diseases or neuropsychiatric conditions. For instance, by analyzing large amounts of brain scans collected using a noninvasive technique known as magnetic resonance imaging (MRI), AI could uncover patterns associated with tumors, strokes and neurodegenerative diseases, which could help to diagnose these conditions.
Researchers at Mass General Brigham, Harvard Medical School and other institutes recently developed Brain Imaging Adaptive Core (BrainIAC), a large AI system pre-trained on a vast pool of MRI data that could be adapted to tackle different tasks. This foundation model, presented in a paper published in Nature Neuroscience, was found to outperform many models that were trained to complete specific medical or neuroscience-related tasks.
Long-living wild mouse may hold secret to healthy aging
When it comes to health, some of our animal neighbors have extraordinary advantages. Ostriches, for example, are highly resistant to viruses, while sharks rarely develop cancer. And species like naked mole rats and bowhead whales live for astonishingly long periods of time, decades and centuries, respectively.
Researchers are now starting to understand why another species—the golden spiny mouse—seems to be unhindered by the negative health effects that typically accompany aging.
Reporting in Science Advances, researchers at Yale School of Medicine (YSM) have begun to uncover how this wild mouse, native to rocky deserts in the Middle East, resists physical, cognitive, and immunological decline while living six to seven times longer than other wild mice.
Varicella zoster virus and the central nervous system
Varicella zoster virus (VZV) infection causes varicella and herpes zoster and, rarely, severe central nervous system (CNS) complications, including encephalitis. Ogunjimi et al. review the evidence linking herpes zoster with stroke and dementia, summarize innate and adaptive immune responses to VZV-related CNS disease, and debate the consequences of vaccination.
FDA-Approved Seizure Drug May Stop Alzheimer’s Before It Starts
Unlike treatments that focus on removing plaques that have already formed, levetiracetam works differently. It blocks the production of toxic amyloid beta peptides in the first place.
These biological computers actually use neurons
In this video we look into one of the developing areas of computing: wetware. Most specifically neuromorphic computing, a science which uses actual neurons on chips.
We talk to Cortical labs, the company that developed the pong-playing dish brain, and professor Thomas Hartung to understand what the benefits of this technology are.

Dorsal Amygdala Neurotrophin-3 Decreases Anxious Temperament in Primates
An early-life anxious temperament (AT) is a risk factor for the development of anxiety, depression, and comorbid substance abuse. We validated a nonhuman primate model of early-life AT and identified the dorsal amygdala as a core component of AT’s neural circuit. Here, we combine RNA sequencing, viral-vector gene manipulation, functional brain imaging, and behavioral phenotyping to uncover AT’s molecular substrates.
