In today’s hospitals and clinics, a dermatologist may use an artificial intelligence model for classifying skin lesions to assess if the lesion is at risk of developing into a cancer or if it is benign. But if the model is biased toward certain skin tones, it could fail to identify a high-risk patient.In today’s hospitals and clinics, a dermatologist may use an artificial intelligence model for classifying skin lesions to assess if the lesion is at risk of developing into a cancer or if it is benign.

Representing the pathway of participants in a study is a key element in clinical and epidemiological research. Flow diagrams are the standard tool to do so, as they allow the different stages of the process to be clearly visualized, from initial selection to final analysis, following international guidelines such as CONSORT or STROBE. However, their creation is often laborious. It usually involves manually entering data or programming complex structures, which makes reproducibility more difficult and may increase the risk of errors.Representing the pathway of participants in a study is a key element in clinical and epidemiological research.

Most contemporary artificial intelligence (AI) systems learn to complete tasks via machine learning and deep learning. Machine learning is a computational approach that allows models to uncover patterns in data that are useful for making predictions. Deep learning, on the other hand, is a subset of machine learning that entails the use of multi-layered neural networks, which can autonomously extract features and learn complex patterns from unstructured data, sometimes with little or no human supervision.Most contemporary artificial intelligence (AI) systems learn to complete tasks via machine learning and deep learning.

Attempts to define human beauty using artificial intelligence may reveal more about bias in data than universal standards, according to a new analysis from the University of Virginia’s School of Data Science. Using computer vision and statistical modeling, researchers evaluated whether facial features align with the “Golden Ratio,” a mathematical formula often cited as an objective measure of attractiveness. Instead, the analysis found that demographic variation, not mathematical proportion, was the strongest factor shaping model outputs. This challenges long-standing assumptions that beauty can be quantified.Attempts to define human beauty using artificial intelligence may reveal more about bias in data than universal standards, according to a new analysis from the University of Virginia’s School of Data Science.

Cyclists can feel safe at the very moment they are most at risk, according to new Monash research that could reshape how cities design shared streets. The study, published in Accident Analysis & Prevention, found that after a vehicle overtakes a cyclist, riders often experience a short “perceptual relief period” where they feel safer, even though the risk from vehicles behind them remains high.Cyclists can feel safe at the very moment they are most at risk, according to new Monash research that could reshape how cities design shared streets.

Confidence is persuasive. In artificial intelligence systems, it is often misleading. Today’s most capable reasoning models share a trait with the loudest voice in the room: They deliver every answer with the same unshakable certainty, whether they’re right or guessing. Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have now traced that overconfidence to a specific flaw in how these models are trained, and developed a method that fixes it without giving up any accuracy. The team’s research is published on the arXiv preprint server.Confidence is persuasive. In artificial intelligence systems, it is often misleading.

AI chatbot teaches AI ‘student’ to love owls, even after data is scrubbedon April 15, 2026 at 3:40 pm
Large language models (LLMs) can teach other algorithms unwanted traits, which can persist even when training data has been scrubbed of the original trait, according to new research published in Nature. In one example, a model seems to transmit a preference for owls to other models via hidden signals in data. The findings demonstrate that more thorough safety checks are needed when producing LLMs.Large language models (LLMs) can teach other algorithms unwanted traits, which can persist even when training data has been scrubbed of the original trait, according to new research published in Nature.

CacheMind turns chip tuning into a conversation, exposing hidden cache failures and lifting processor performanceon April 15, 2026 at 11:40 am
Researchers at North Carolina State University have developed a new AI-assisted tool that helps computer architects boost processor performance by improving memory management. The tool, called CacheMind, is the first computer architecture simulator capable of answering arbitrary, interactive questions about complex hardware-software interactions.Researchers at North Carolina State University have developed a new AI-assisted tool that helps computer architects boost processor performance by improving memory management.

Perfect alignment between AI and human values is mathematically impossible, study sayson April 14, 2026 at 12:20 pm
Perfect AI alignment with human values and interests is mathematically impossible, according to a study, but behavioral diversity among AI agents offers the promise of some control. Published in PNAS Nexus, Hector Zenil and colleagues used Gödel’s incompleteness theorem and Turing’s undecidability result for the Halting Problem to show that any LLM complex enough to exhibit general intelligence or superintelligence will also be computationally irreducible and produce unpredictable behavior, making forced alignment impossible.Perfect AI alignment with human values and interests is mathematically impossible, according to a study, but behavioral diversity among AI agents offers the promise of some control.
