A large-scale study led by Bilal Farooq, civil engineering professor at Toronto Metropolitan University (TMU), is the first of its kind to use virtual reality (VR) to study pedestrian interactions and street crossing behaviors. The research pioneers the use of neurophysiological sensors to better understand pedestrian experiences in urban environments. The work is published in the journal Transportation Research Part C: Emerging Technologies.

The world is facing a "silver tsunami"—an unprecedented aging of the global workforce. By 2030, more than half of the labor force in many EU countries will be aged 50 or above. Similar trends are emerging across Australia, the US and other developed and developing economies.

A group of computer scientists at Microsoft Research, working with a colleague from the University of Chinese Academy of Sciences, has introduced Microsoft's new AI model that runs on a regular CPU instead of a GPU. The researchers have posted a paper on the arXiv preprint server outlining how the new model was built, its characteristics and how well it has done thus far during testing.

Step by mechanical step, dozens of humanoid robots took to the streets of Beijing early Saturday, joining thousands of their flesh-and-blood counterparts in a world-first half marathon showcasing China's drive to lead the global race in cutting-edge technology.

AI models often rely on "spurious correlations," making decisions based on unimportant and potentially misleading information. Researchers have now discovered these learned spurious correlations can be traced to a very small subset of the training data and have demonstrated a technique that overcomes the problem. The work has been published on the arXiv preprint server.

Programmers can now use large language models (LLMs) to generate computer code more quickly. However, this only makes programmers' lives easier if that code follows the rules of the programming language and doesn't cause a computer to crash.

Creativity is no longer exclusive to humans. Some forms of artificial intelligence are capable of producing poetry, entrepreneurial concepts, even visual art. Many people use large language models (LLMs) such as ChatGPT, which are trained on vast amounts of text, for co-creation: The artificial intelligence offers ideas and suggestions, while the human provides guidance, context, and direction.

As television grew rapidly in popularity in the second half of the 20th century, many people assumed it would cause a knock-on crisis for the film industry. After all, it meant that viewers no longer had to leave their sofas to enjoy onscreen entertainment.

ChatGPT and other AI chatbots based on large language models are known to occasionally make things up, including scientific and legal citations. It turns out that measuring how accurate an AI model's citations are is a good way of assessing the model's reasoning abilities.

As Internet of Things (IoT) devices proliferate in sectors like smart cities, health care, and industrial systems, they have become prime targets for cyberattacks such as Distributed Denial of Service (DDoS), ransomware, and botnets. However, traditional security methods struggle to cope with these attacks due to the limited computational power of IoT devices and the dynamic nature of cyber threats.

When some commuter trains arrive at the end of the line, they must travel to a switching platform to be turned around so they can depart the station later, often from a different platform than the one at which they arrived.

A team of Lehigh University researchers has successfully predicted abnormal grain growth in simulated polycrystalline materials for the first time—a development that could lead to the creation of stronger, more reliable materials for high-stress environments, such as combustion engines. A paper describing their novel machine learning method was recently published in Nature Computational Materials.

AI models like ChatGPT have amazed the world with their ability to write poetry, solve equations and even pass medical exams. But they can also churn out harmful content, or promote disinformation.

Earlier this year, scientists discovered a peculiar term appearing in published papers: "vegetative electron microscopy."

Fraud is widespread in the United States and increasingly driven by technology. For example, 93% of credit card fraud now involves remote account access, not physical theft. In 2023, fraud losses surpassed $10 billion for the first time.

As we mature from childhood, our vocabulary—as well as the ways we use it—grows, and our experiences become richer, allowing us to think, reason, and interact with others with specificity and intention. Accordingly, our word choices evolve to align with our personal values, ethics, cultural norms, and views.

The Titanic sank 113 years ago on April 14–15, after hitting an iceberg, with human error likely causing the ship to stray into those dangerous waters. Today, autonomous systems built on artificial intelligence can help ships avoid such accidents, but could such a system explain to the captain why it was maneuvering a certain way?
