Scientists have achieved an incredible breakthrough by recreating the brain of a fruit fly inside a computer simulation. By mapping around 140,000 neurons and millions of connections, they built a digital brain that can sense its environment, process information, and even control a virtual body. In the simulation, the digital fly was able to search for food, respond to stimuli, and show behaviors that were not directly programmed by scientists. This discovery shows how powerful neural connections are in generating behavior. It also raises fascinating questions about the nature of intelligence, consciousness, and whether complex brains—including ours—could one day be simulated in computers.

Can AI build AI? Yes, and it already is. Sort of. I showcase the ability of AI agents like claude code to perform AI research, to build and optimize machine learning algorithms. I put various state-of-the-art LLMs like claude Mythos/Fable into an endless recursive research loop and have them build a neural network that learns the shape of the mandelbrot set. It is inspired by Andrej Karpathy’s autoresearch. While we watch this loop, I express my thoughts on the concept of recursive self improvement, arguing that it is possible, hard, and dangerous.
Sorry for the bitrate issues.

What will the world really look like in 100 years?
Forget flying cars, impossible megacities, and science-fiction fantasies. This documentary explores a realistic vision of life in the year 2,126 based on current trends in artificial intelligence, climate adaptation, biotechnology, energy, space exploration, economics, and human evolution.
How will cities change as the planet warms? What happens when AI becomes part of everyday life? Will humans live to 120 years? Will neural implants blur the line between biology and technology? Could Mars become a permanent home for thousands of people? And what happens to society when work, truth, privacy, and even human identity are redefined?
Travel one century into the future and discover a world that is both familiar and radically different from our own. A world shaped by the choices humanity is making right now.
From climate-engineered cities and fusion-powered civilizations to Martian settlements, artificial intelligence, genetic medicine, digital consciousness, and the search for life beyond Earth, this is a deep exploration of the most plausible future awaiting our species.
The future isn’t written.
Einstein’s famous equation has grown into one of the great symbols of the 20th century. It is the one equation in science that people recognize, if any is. It has a kind of iconic status and dual connotations: the brilliance and insight of Einstein and the darkness of atomic bombs. Images.
The basic idea behind the formula E=mc2 is easy to state. Mass and energy are really just the same thing. At first that seems impossible.
• Mass is a measure of the quantity of stuff and manifests as a resistance to acceleration. A body with little mass, like a pebble, is easy to set in motion.
New research co-led by Indiana University School of Medicine scientists presents a significant step toward more precise and effective cancer treatments by using a breakthrough method to deliver therapies directly to cancer cells. The study was recently published in ACS Nano.
“One of the biggest challenges in cancer treatment is that many drugs not only attack cancer cells but also harm healthy cells throughout the body,” said Ngoc Tung Tran, Ph.D., the study’s co-lead author and an assistant professor of pediatrics and of microbiology and immunology at the IU School of Medicine. “This can lead to serious side effects and limit how well the treatment works. Our goal is to develop a smarter way to deliver cancer therapy directly to cancer cells while avoiding normal tissues.”
In the study, researchers focused on multiple myeloma, a blood cancer that mainly grows in plasma cells found in the bone marrow. Using mouse models, they carried therapeutic molecules into cells by using a delivery system of tiny, fat-based particles called lipid nanoparticles, or LNPs.
We tend to assume that emotionally charged words are more likely to grab our attention. An insult shouted across a crowded room or a disturbing phrase overheard on television can seem impossible to ignore. But a new study published in Psychological Science suggests the opposite may happen before words reach conscious awareness.
Researchers at the Hebrew University of Jerusalem found that when people were focused on a visual task, they were less likely to consciously notice negative spoken words than neutral ones. The findings offer new insight into how the brain determines which information enters conscious awareness and which remains outside it.
“This study is a nice example of how our conscious intuitions regarding what we notice are not always what our unconscious is doing,” said lead author Gal R. Chen, a doctoral candidate in psychology at the Hebrew University of Jerusalem.
Researchers at the University of Illinois Chicago have developed an anti-cancer therapy inspired by bacteria found in cancer tumors.
When tested in combination with radiation in animal models of prostate cancer, it was highly effective — the approach effectively shut down tumor growth. The therapy is made from a fragment of a bacterial protein, a peptide called aurB. In cancer tumors in the animal models, aurB prevented energy production in the tumor cells’ mitochondria, essentially cutting off the tumor’s fuel, the researchers report in the journal Signal Transduction and Targeted Therapy.
“The mitochondria are very important for a cell to survive; they are the energy factories,” said Tohru Yamada, senior author on the study, associate professor in the departments of surgery and biomedical engineering at UIC and a member of the University of Illinois Cancer Center. “Many cancer cells exhibit altered mitochondrial number and activity, because a cancer cell has to grow aggressively and rapidly. Therefore, the mitochondria would be an ideal target for cancer therapy.”
