Largest Brain Map Ever Reveals Hidden Algorithms of the Mammalian Brain

1 week ago | singularityhub.com | Shelly Fan

Let a mouse nose around a house, and it will rapidly find food and form a strategy to return to it without getting caught. Given the same task, an AI would require millions of training examples and consume a boatload of energy and time. Evolution has crafted the brain to quickly learn and adapt to an ever-changing world. Detailing its algorithms—the ways it processes information as revealed by its structure and wiring—could inspire more advanced AI.
DeepMind’s New AI Teaches Itself to Play Minecraft From Scratch

1 week ago | singularityhub.com | Shelly Fan

My nephew couldn’t stop playing Minecraft when he was seven years old. One of the most popular games ever, Minecraft is an open world in which players build terrain and craft various items and tools. No one showed him how to navigate the game. But over time, he learned the basics through trial and error, eventually figuring out how to craft intricate designs, such as theme parks and entire working cities and towns.
Our Conscious Perception of the World Depends on This Deep Brain Structure

2 weeks ago | singularityhub.com | Shelly Fan

How consciousness emerges in the brain is the ultimate mystery. Scientists generally agree that consciousness relies on multiple brain regions working in tandem. But the areas and neural connections supporting our perception of the world have remained their grasp. A new study, published in Science, offers a potential answer. A Chinese team recorded the neural activity of people with electrodes implanted deep in their brains as they performed a visual task.
This Brain-Computer Interface Is So Small It Fits Between the Follicles of Your Hair

2 weeks ago | singularityhub.com | Edd Gent

Brain-computer interfaces are typically unwieldy, which makes using them on the move a non-starter. A new neural interface small enough to be attached between the user’s hair follicles keeps working even when the user is in motion. At present, brain-computer interfaces are typically used as research devices designed to study neural activity or, occasionally, as a way for patients with severe paralysis to control wheelchairs or computers.
World’s Tiniest Pacemaker Is Smaller Than a Grain of Rice

2 weeks ago | singularityhub.com | Shelly Fan

Scientists just unveiled the world’s tiniest pacemaker. Smaller than a grain of rice and controlled by light shone through the skin, the pacemaker generates power and squeezes the heart’s muscles after injection through a stint. The device showed it could steadily orchestrate healthy heart rhythms in rat, dog, and human hearts in a newly published study. It’s also biocompatible and eventually broken down by the body after temporary use.
These Solar Cells Are Made of Moon Dust. They Could Power Future Lunar Colonies.

3 weeks ago | singularityhub.com | Edd Gent

NASA's plan to establish a permanent human presence on the moon will require making better use of lunar resources. A new approach has now shown how to make solar cells out of moon dust. Later this decade, the US space agency’s Artemis III mission plans to return astronauts to the moon for the first time in more than half a century. The long-term goal of the Artemis program is to establish a permanent human presence on our nearest celestial neighbor.
Brain Implant ‘Streams’ a Paralyzed Woman’s Thoughts as If She’s Speaking in Near Real Time

3 weeks ago | singularityhub.com | Shelly Fan

A paralyzed woman can again communicate with the outside world thanks to a wafer-thin disk capturing speech signals in her brain. An AI translates these electrical buzzes into text and, using recordings taken before she lost the ability to speak, synthesizes speech with her own voice. It’s not the first brain implant to give a paralyzed person their voice back. But previous setups had long lag times. Some required as much as 20 seconds to translate thoughts into speech.
What Anthropic Researchers Found After Reading Claude’s ‘Mind’ Surprised Them

3 weeks ago | singularityhub.com | Edd Gent

Despite popular analogies to thinking and reasoning, we have a very limited understanding of what goes on in an AI’s “mind.” New research from Anthropic helps pull the veil back a little further. Tracing how large language models generate seemingly intelligent behavior could help us build even more powerful systems—but it could be also be crucial for understanding how to control and direct those systems as they approach and even surpass our capabilities. This is challenging.
Scientists Just Transplanted a Pig Liver Into a Person for the First Time

4 weeks ago | singularityhub.com | Shelly Fan

Our liver has admirable regenerative properties. But it takes a beating every day. Eventually, its tissues scar, and if the organ fails, a liver transplant is the only solution. Donor livers are hard to come by, however. This week, a Chinese team turned to another source—pig livers—and published the first results showing how they function inside a human recipient.
These Tiny Liquid Robots Merge and Split Like ‘Terminator’

1 month ago | singularityhub.com | Shelly Fan

Our cells are like the ultimate soft robots. Made mostly of a liquid interior wrapped inside a fatty shell, they split, stretch, roam, and squeeze into every nook and cranny of the body. Actual robots, not so much. Even soft robots made of flexible materials struggle to deform outside of the physical limits of their building blocks. This month, a team from Korea introduced liquid robots inspired by biological cells.
