This has been one of the craziest years in AI in a long time: endless product launches, boardroom coups, intense policy debates about AI doom, and a race to find the next big thing. But we’ve also seen concrete tools and policies aimed at getting the AI sector to behave more responsibly and hold powerful players accountable. That gives me a lot of hope for the future of AI.

Hybrid Biocomputer Fuses Human Brain Tissue With Computer Chips

Posted by in categories: biotech/medical, cyborgs, information science, mathematics, robotics/AI

Scientists have fused human brain tissue to a computer chip, creating a mini cyborg in a petri dish that can perform math equations and recognize speech.

Dubbed Brainoware, the system consists of brain cells artificially grown from human stem cells, which have been fostered to develop into a brain-like tissue. This mini-brain organoid is then hooked up to traditional hardware where it acts as a physical reservoir that can capture and remember the information it receives from the computer inputs.

The researchers wanted to explore the idea of exploiting the efficiency of the human brain’s architecture to supercharge computational hardware. The rise of artificial intelligence (AI) has massively increased the demand for computing power, but it’s somewhat limited by the energy efficiency and performance of the standard silicon chips.

The Impact of Sugar & Processed Foods on Health with Dr. Robert Lustig

Posted by in categories: biotech/medical, government, health, information science, robotics/AI

In this episode, my guest is Dr. Robert Lustig, M.D., neuroendocrinologist, professor of pediatrics at the University of California, San Francisco (UCSF), and a bestselling author on nutrition and metabolic health. We address the “calories in-calories out” (CICO) model of metabolism and weight regulation and how specific macronutrients (protein, fat, carbohydrates), fiber and sugar can modify the CICO equation. We cover how different types of sugars, specifically fructose, sugars found in liquid form, taste intensity, and other factors impact insulin levels, liver, kidney, and metabolic health. We also explore how fructose in non-fruit sources can be addictive (acting similarly to drugs of abuse) and how sugar alters brain circuits related to food cravings and satisfaction. We discuss the role of sugar in childhood and adult obesity, gut health and disease and mental health. We also discuss how the food industry uses refined sugars to create pseudo foods and what these do to the brain and body. This episode is replete with actionable information about sugar and metabolism, weight control, brain health and body composition. It ought to be of interest to anyone seeking to understand how specific food choices impact the immediate and long-term health of the brain and body.

We Now Have Precise Math To Describe How Black Holes Reflect Our Universe

Posted by in categories: cosmology, information science, mathematics, physics

Astronomers developed a set of equations that can precisely describe the reflections of the Universe that appear in the warped light around a black hole.

The proximity of each reflection is dependent on the angle of observation with respect to the black hole, and the rate of the black hole’s spin, according to a mathematical solution worked out by physics student Albert Sneppen of the Niels Bohr Institute in Denmark in July 2021.

This was really cool, absolutely, but it wasn’t just really cool. It also potentially gave us a new tool for probing the gravitational environment around these extreme objects.

What Kant Can Teach Us About the Limits of AI

Posted by in categories: information science, robotics/AI

Unlike us, an algorithm selecting a most-likely next word or a program calculating the best move in a game of chess isn’t choosing and can’t feel regret.


A key aspect of how we think separates us from even the most advanced AI.

Tiny biobots surprise their creators by healing wound

Posted by in categories: biotech/medical, information science, neuroscience

Tiny made from human windpipe cells encouraged damaged neural tissue to repair itself in a lab experiment — potentially foreshadowing a future in which creations like this patrol our bodies, healing damage, delivering drugs, and more.

The background: In a study published in 2020, researchers at Tufts University and the University of Vermont (UVM) harvested and incubated skin cells from frog embryos until they were tiny balls.

P vs. NP: The Greatest Unsolved Problem in Computer Science

Posted by in categories: computing, information science, mathematics, science

Is it possible to invent a computer that computes anything in a flash? Or could some problems stump even the most powerful of computers? How complex is too complex for computation? The question of how hard a problem is to solve lies at the heart of an important field of computer science called computational complexity. Computational complexity theorists want to know which problems are practically solvable using clever algorithms and which problems are truly difficult, maybe even virtually impossible, for computers to crack. This hardness is central to what’s called the P versus NP problem, one of the most difficult and important questions in all of math and science.

This video covers a wide range of topics including: the history of computer science, how transistor-based electronic computers solve problems using Boolean logical operations and algorithms, what is a Turing Machine, the different classes of problems, circuit complexity, and the emerging field of meta-complexity, where researchers study the self-referential nature of complexity questions.
