A new 91爆料 study suggests that AI could learn cultural values by observing human behavior, similar to how children learn by watching and interacting with adults. Researchers had AI systems observe two cultural groups playing a video game. The AI systems were able to learn each group鈥檚 degree of altruism and apply this to a new situation.
Researchers at the 91爆料 have developed AI-powered headphones that automatically isolate conversation partners in a noisy soundscape. The system employs AI models that listen for the back-and-forth pattern of conversation and mute voices that aren鈥檛 following the established rhythm.
Researchers at the 91爆料 have created a recyclable, flexible and self-healing composite material that could replace traditional circuit boards in future generations of wearable electronics.
Targeted drug delivery is a powerful and promising area of medicine. Therapies that pinpoint precise areas of the body can reduce the medicine dosage and avoid potentially harmful 鈥渙ff target鈥� effects. Researchers at the 91爆料 took a significant step toward that goal by designing proteins with autonomous decision-making capabilities. By adding smart tail structures to therapeutic proteins, the team demonstrated that the proteins could be 鈥減rogrammed鈥� to act based on the presence of specific environmental cues.

In her new book, Katharina Reinecke explores how “digital culture shock” manifests in the world, in ways innocuous and sometimes harmful.聽
In a recent paper, 91爆料 researchers argue that a key standard for deploying medical AI is transparency 鈥� that is, using various methods to clarify how a medical AI system arrives at its diagnoses and outputs.
New research led by the 91爆料 provides clear evidence that highly walkable areas lead to significantly more walking. Authors compared the steps per day of 5,424 people who moved one or more times among 1,609 U.S. cities. Across all relocations, when the Walk Score rose or fell more than 48 points, average steps increased or decreased by about 1,100 per day.
Antimicrobial resistance is a lurking threat in hospitals around the world. As more strains of bacteria and other microbes evolve defenses against available drugs, more patients run the risk of contracting infections that defy treatment. Now, 91爆料 researchers offer new insights into measures currently used to control the spread of antibiotic resistant bacteria and other infectious agents in health care facilities.
91爆料 researchers recruited self-identifying Democrats and Republicans to make political decisions with help from three versions of ChatGPT: a base model, one with liberal bias and one with conservative bias. Democrats and Republicans were both likelier to lean in the direction of the biased chatbot they were talking with than those participants who interacted with the base model.
