Scientists Say Human Brain Simulation Is Now Possible

Life of leonard susskind;leonard susskind physics.

*Description:*
Can scientists really simulate a full human brain now? In this video, we explore the latest study claiming that supercomputers may soon be powerful enough to simulate the human brain. We break down how this new method works, why previous brain simulation projects failed, what makes this new research different, and the big ethical questions that come with it. Is this the future of neuroscience and artificial intelligence, or are we still far from creating a true digital human mind? Watch till the end to understand the science in simple words.

Advancements and challenges in inverse lithography technology: a review of artificial intelligence-based approaches

Inverse lithography takes a radically different approach. Instead of starting with the desired circuit pattern and tweaking it to compensate for optical distortions, ILT works backwards. It asks: “What mask pattern would produce the exact shape we want after the light does its distorting work?” It’s like designing a funhouse mirror that makes your reflection look perfectly normal.

What’s particularly elegant are the “model-driven deep learning” approaches, which combine the physics of how light actually behaves with AI’s pattern-recognition abilities. Rather than making the AI learn optics from scratch, these hybrid methods embed the known laws of physics into the learning process, creating solutions that are both fast and physically accurate.

Does the Universe spin? Think about it, planets spin, the Sun spins, galaxies spin, even black holes spin — so what about the entire Universe? And if it was spinning could this help solve one of the biggest problems in astrophysics today — the \.

A student-led experiment sets new limits in the search for axions

In the era of precision cosmology, research often means big science: large observatories, highly complex instruments, international collaborations and substantial funding. Yet even in such an advanced field, progress is still possible—including in the search for elusive dark matter—through more agile approaches, driven by small teams and young researchers, supported by institutions and a good dose of ingenuity.

In a paper titled “A New Limit for Axion Dark Matter with SPACE” published in the Journal of Cosmology and Astroparticle Physics, a group of then-undergraduate students from the University of Hamburg built a cavity detector to search for axions—among the most promising candidates for dark matter—and set new experimental limits on their properties.

The result was achieved with relatively limited resources, showing that even small-scale experiments can make a meaningful contribution to one of the most open challenges in modern physics.

Additive Manufacturing in Microgravity

The most expensive part of space travel isn’t the fuel. It’s the cargo. Additive manufacturing isn’t a sci-fi magic trick; it’s the key to building shipyards and telescopes at scales rockets were never meant to handle. We aren’t just launching ships anymore; we’re moving the factory to the void.

AI and the mysteries of reality

Does AI have the potential to uncover the mysteries of reality, or does it lack the capacity for genuine discovery?

With the 2024 Nobel Prizes for physics and chemistry both awarded for AI-related science, claims that AI will soon make novel scientific breakthroughs on its own are growing louder.

Start-ups are already attempting to create “The AI Scientist,” and researchers at Imperial College argue AI will “usher in a new age of discovery to rival the golden age of the scientific method.” But critics argue the scientific capability of AI remains unknown.

Join computer scientist Roman Yampolskiy, philosopher Steve Fuller, and co-curator of “AI: More than Human” Suzanne Livingston to debate what AI can and can’t do for science.

The 2024 Nobel Prizes for physics and chemistry were both won for AI-related science, leading some to claim that AI will soon be making novel scientific discoveries on its own. Start-ups are already attempting to create “The AI Scientist,” which will one day “fully automate scientific discovery.” And researchers at Imperial College argue AI will.

New methods can help study the phenomenon of turbulence

In his doctoral thesis, Michael Roop develops numerical methods that allow finding physically reliable approximate solutions to nonlinear differential equations used to model turbulence.

Many processes in nature can be described by differential equations, but only a few of them can be solved explicitly with solutions in formulas. This is the motivation for developing numerical equations to find approximate solutions. The numerical equations developed in Roop’s thesis have a particular focus on geometric properties. Though the thesis is mathematical, the problems it addresses originate in physics and mainly have to do with magnetohydrodynamic (MHD) turbulence.

“It is difficult to define turbulence rigorously. Intuitively, you can think of the turbulent behavior when a fluid moves, but it is very hard to predict how it will behave in the future. It looks chaotic though there is no randomness in the models of motion.”

Cosmic Strings — Cracks in the Fabric of the Universe

Cosmic strings may be ultra-thin defects in spacetime—relic “cracks” from the early universe. How we’d detect them, what they mean for physics, and how aliens might exploit them.
