Artificial Intelligence (AI), particularly large language models like GPT-4, has shown impressive performance on reasoning tasks. But does AI truly understand abstract concepts, or is it just mimicking patterns? A new study reveals that while GPT models perform well on some analogy tasks, they fall short when the problems are altered, highlighting key weaknesses in AI's reasoning capabilities. Read more ›

Researchers have applied a visualization technique to depict the brain's activity related to visual perception as geometric patterns. They visualized different shapes as the ever-changing neuronal activity in the temporal and frontal lobes of the brain during object recognition and recalling memories. This achievement promises further extraction of brain activity observed in various aspects of daily life. Read more ›

A research team has developed a groundbreaking method for synthesizing perovskite nanocrystals (PNCs), a next-generation semiconductor material, in a more uniform and efficient manner. This study is expected to serve as a key breakthrough in overcoming the complexities of conventional synthesis methods and accelerating the commercialization of various optoelectronic devices, such as light-emitting diodes (LEDs) and solar cells, that utilize nanocrystals.

Optical atomic clocks can increase the precision of time and geographic position a thousandfold in our mobile phones, computers, and GPS systems. However, they are currently too large and complex to be widely used in society. Now, a research team has developed a technology that, with the help of on-chip microcombs, could make ultra-precise optical atomic clock systems significantly smaller and more accessible -- with significant benefits for navigation, autonomous...

Rubidium could be the next key player in oxide-ion conductors. Researchers have discovered a rare rubidium (Rb)-containing oxide-ion conductor with exceptionally high conductivity. Identified through computational screening and experiments, its superior performance stems from low activation energy and structural features like large free volume and tetrahedral motion. Its stability under various conditions offers a promising direction for solid oxide fuel cells and clean energy technologies. Read more ›

Groundbreaking study shows machine learning can decode emotions in seven ungulate species. A game-changer for animal welfare? Can artificial intelligence help us understand what animals feel? A pioneering study suggests the answer is yes. Researchers have successfully trained a machine-learning model to distinguish between positive and negative emotions in seven different ungulate species, including cows, pigs, and wild boars. By analyzing the acoustic patterns of their vocalizations, the model achieved... Read more ›

Because almost no existing programs focus specifically on reducing ultra-processed food (UPF) intake, researchers recently designed an intervention that included a variety of tactics to target the uniquely problematic aspects of UPFs. On average, participants successfully reduced their UPF intake by almost half. Read more ›

Adding engineered human blood vessel-forming cells to islet transplants boosted the survival of the insulin-producing cells and reversed diabetes in a preclinical study. The new approach, which requires further development and testing, could someday enable the much wider use of islet transplants to cure diabetes. Read more ›

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration has now explored the effects of multiple thermal cycles on microstructures and interactions between different layers of perovskite solar cells. They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising... Read more ›
