For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles and fields. Both work brilliantly in their own domains. But put them together and contradictions appear—especially when it comes to black holes, dark … Read more
Despite their usefulness, large language models still have a reliability problem. A new study shows that a team of AIs working together can score up to 97 percent on US medical licensing exams, outperforming any single AI. While recent progress in large language models (LLMs) has led to systems capable of passing professional and academic … Read more
Artificial Intelligence Nvidia Researchers Boost LLM Reasoning Skills by Getting Them to ‘Think’ During Pre-trainingBen Dickson | VentureBeat “This approach encourages the model to ‘think for itself before predicting what comes next, thus teaching an independent thinking behavior earlier in the pretraining,’ the researchers state in their paper. [Models trained like this] show significant improvements … Read more
The brain is like a city within a fortress. Its cellular inhabitants normally hum along in their daily routines. Neurons send out the electrical signals underlying memory and cognition. Supporting cells provide nutrients and fine-tune neural signals. Immune cells keep an eye out for infection and other dangers. A liquid bath washes away toxic proteins. … Read more
The relentless shrinking of silicon components has led to exponential improvements in chip performance, but we’re starting to hit physical limits. Now researchers have developed a way to integrate materials just 10 atoms thick into conventional chips. For decades, rapid advances in miniaturization meant the number of transistors on a microchip doubled approximately every two … Read more
At the turn of the 20th century, Korbinian Brodmann released one of the most consequential brain maps ever. By studying the humps, grooves, layers, and cells of the cortex—the outermost layer of the brain—he divided the wrinkly tissue into 52 distinct areas. Brodmann’s map was based solely on microscopic images of the brain. Since then, … Read more
Over the past five years, private-sector funding for fusion energy has exploded. The total invested is approaching $10 billion, from a combination of venture capital, deep-tech investors, energy corporations, and sovereign governments. Most of the companies involved (and the cash) are in the United States, though activity is also increasing in China and Europe. Why … Read more
Artificial Intelligence Self-Improving Language Models Are Becoming Reality With MIT’s Updated SEAL TechniqueCarl Franzen | VentureBeat “Researchers at [MIT] are gaining renewed attention for developing and open sourcing a technique that allows large language models (LLMs)—like those underpinning ChatGPT and most modern AI chatbots—to improve themselves by generating synthetic data to fine-tune upon.” Biotechnology 95% … Read more
