We Are Creating Artificial Brains

The Big Why explores the cutting edge of science and technology: Artificial Brains! đŸ§ đŸ€– In this mind-blowing video, we dive into the quest to replicate the human brain’s complexity and power in a machine.

Discover the various approaches scientists are taking, from simulating neural networks to building brain-like hardware. We’ll examine the potential of this technology to revolutionize medicine, robotics, and even our understanding of consciousness.

But we won’t shy away from the big questions either: Could artificial brains surpass human intelligence? What are the ethical implications of creating conscious machines? Join us as we ponder the future of AI and the potential for a technological singularity.

Printed Artificial Neurons That Communicate with Living Brain Cells

Artificial Neurons That Talk to the Brain? A Major Breakthrough in Neurotechnology
What if machines could communicate directly with your brain?

Scientists at Northwestern University have developed *printed artificial neurons* that can interact with real brain cells—sending signals that closely mimic natural neural activity. This breakthrough could redefine how we treat neurological disorders and build the next generation of energy-efficient AI systems.

In this video, we explore how these artificial neurons work, how they were tested on real brain tissue, and why this discovery could lead to revolutionary technologies like brain-machine interfaces and neuromorphic computing.

🔬 *What you’ll learn:*

How artificial neurons mimic real brain signals
Why traditional computing struggles with energy efficiency
The role of advanced materials like graphene and MoS₂
How this technology could restore vision, hearing, or movement
What neuromorphic computing means for the future of AI

🚀 *Why this matters:*

Why Trump Supporters Stay Loyal No Matter What | Psychology Explains

#HumanBehavior.

This Video is For Educational Purpose Only
 It doesn’t have to be true in anyway. Everything is based on ones opinions and not a false narration.

This video examines the psychological factors behind strong political loyalty, using support for Trump as a case study. Based on findings from behavioral science and social psychology, it explores why some people continue to defend beliefs even when faced with opposing evidence.

Topics covered include cognitive dissonance, identity-protective thinking, and social dominance orientation—concepts that help explain how people process information, protect group identity, and remain committed to a political worldview.

This is not a partisan attack or political endorsement. It is an exploration of human behavior, showing how emotion, identity, and perception often shape decisions more powerfully than facts alone.

If you want to better understand why changing minds is so difficult in politics, this video provides a thoughtful, research-informed perspective.

Artificial Brain Controlled Robot

The GSN SNN 4−10−30−2 is a hardware based spiking neural network that can autonomous control a remote control robot vehicle. There are 10 artificial neurons and 30 artificial synapses, and is built on 16 full-size breadboards. Four infrared proximity sensor are used on top of the vehicle to determine how far it is away from objects and walls. The sensor data is used as inputs into the first later of neurons.

A full circuit level diagram of the neural network is provided, as well as an architecture diagram. The weights on the network are set based on the resistance value. The synapses allow the weights to be set as excitatory or inhibitory.

Testing of the network went great and the robot had much smoother control than previous testing as the output now has an analog output.

The Age of Biohacking: Redefining Human Potential in the 21st Century

In a world where technology and biology converge at an accelerating pace, a new era of self-improvement is emerging — biohacking. This once-niche movement has transformed into a global phenomenon, attracting everyone from Silicon Valley executives to amateur enthusiasts. The promise? To optimize the human mind and body beyond natural limits using a blend of science, lifestyle adjustments, and cutting-edge technology.

But what exactly is biohacking? Is it the future of personal health and evolution, or a slippery slope into risky experimentation? In this article, we’ll delve deep into the world of biohacking — its origins, principles, popular techniques, controversies, and future potential. Whether you’re a skeptic, a curious observer, or a self-improvement junkie, the world of biohacking has something provocative for everyone.

Many minds, not many worlds, constitute quantum reality

A century after the birth of quantum mechanics, many are still puzzled by the idea that Schrödinger’s cat is simultaneously alive and dead. The mystery drives some of our most prominent physicists to embrace the bizarre idea that reality constantly splits into a near infinity of parallel worlds, of which ours is just one. Philosopher of physics Nadia Blackshaw argues that this “many worlds” interpretation goes wrong not only in its extravagant multiplying of entities, but in its attempt to adopt a “view from nowhere,” describing reality from no particular perspective. She proposes instead a “many minds” interpretation, in which the cat is alive from one perspective and dead from another. It’s time physics took conscious perspectives seriously.

Glial Cells as Emerging Therapeutic Targets in Neurodegenerative Diseases: Mechanistic Insights and Translational Perspectives

Neurodegenerative diseases such as Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease, multiple sclerosis, and amyotrophic lateral sclerosis share converging mechanisms of neuronal dysfunction, including protein aggregation, oxidative stress, and chronic neuroinflammation. Glial cells, once considered passive supporters, are now recognized as central drivers of these processes, offering both pathogenic triggers and therapeutic opportunities. Yet, despite compelling preclinical evidence, the translation of glial-targeted therapies into clinical success has been limited. This review provides a critical synthesis of current knowledge by examining therapeutic strategies through the lens of their translational challenges and failures.
