Chatbots can wear a lot of proverbial hats: dictionary, therapist, poet, all-knowing friend. The artificial intelligence models that power these systems appear exceptionally skilled and efficient at providing answers, clarifying concepts, and distilling information. But to establish trustworthiness of content generated by such models, how can we really know if a particular statement is factual, a hallucination, or just a plain misunderstanding?

In many cases, AI systems gather external information to use as context when answering a particular query. For example, to answer a question about a medical condition, the system might reference recent research papers on the topic. Even with this relevant context, models can make mistakes with what feels like high doses of confidence. When a model errs, how can we track that specific piece of information from the context it relied on — or lack thereof?

To help tackle this obstacle, MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) researchers created ContextCite, a tool that can identify the parts of external context used to generate any particular statement, improving trust by helping users easily verify the statement.


The ContextCite tool from MIT CSAIL can find the parts of external context that a language model used to generate a statement. Users can easily verify the model’s response, making the tool useful in fields like health care, law, and education.

Nearly half a dozen institutions of higher education separately announced plans this week to make tuition free for undergraduates who meet certain income requirements, reflecting a growing nationwide effort to make college more affordable.

The schools span states from Massachusetts to New Mexico, and include some of the country’s leading universities. They all announced their initiatives within days of each other. And while the specific financial requirements for current students applicants vary between schools, all are slated to take effect in fall 2025.

The Massachusetts Institute of Technology in Cambridge, for example, says undergraduates with family income below $200,000 can attend tuition free starting next year, up from its current threshold of $140,000. It said in its announcement that 80% of American households meet the updated threshold.

PRESS RELEASE — Thirty years ago, the University of the Andes made the first internet connection in Colombia, and on Tuesday, December 3, the country’s first quantum computer will be unveiled. This acquisition marks a turning point in education and technological research, fostering interdisciplinary collaboration and enhancing ongoing efforts by researchers at the University of the Andes and other institutions.

The University’s Faculties of Science and Engineering announced the arrival of the device, which will enable students and professors to explore fundamental aspects of quantum computing. This emerging technology seeks to solve problems and process information differently by leveraging the laws of quantum physics.

Professor Julián Rincón, a theoretical physicist, explains that this quantum computer employs a technique known as Nuclear Magnetic Resonance and operates at room temperature. This makes it particularly suitable for educational purposes, as it is easy to assemble and provides a straightforward way to test fundamental concepts. “This isn’t just a faster conventional computer; it’s a completely new way of processing information, based on the laws of quantum physics,” he clarifies.

Migraine is often misunderstood, with many people facing stigma due to the invisible nature of the illness. Effective treatment is essential for managing migraine attacks, but education and support from the public and medical community are also crucial for validating the experiences of those affected.

A team of physics educators from Italy, Hungary, Slovenia, and Germany is pioneering a new approach to teaching quantum physics in schools. Traditional classroom methods have typically emphasized the history and origins of quantum physics, which can often create challenges for learners.

The researchers, including physics education specialist Professor Philipp Bitzenbauer from Leipzig University, focus on qubits—two-state systems that are both the simplest and most crucial quantum systems, capable of describing many situations. Mastering the control and manipulation of these qubits is fundamental to advancing modern quantum technologies.

According to Bitzenbauer, until now there have been no empirical studies of the effectiveness of these approaches using two-state systems in developing conceptual understanding in learners. There is also a lack of scientific research on the specific advantages and disadvantages for learning of different teaching approaches based on two-state systems.

The BBC speaks to residents and travellers in some of the top-ranked countries on the 2024 Global Innovation Index to find out how cutting-edge technology benefits day-to-day life.

With the rise of AI, self-driving cars and wi-fi connected appliances, it can feel like innovation is everywhere these days. But certain countries are known for developing cutting-edge technologies that benefit residents and visitors alike.

To dive into those countries making the most impact in these areas, the World Intellectual Property Organisation recently released its 2024 Global Innovation Index, ranking 130 economies based on measures like their education system, technology infrastructure and knowledge creation (like patents filed or mobile apps created).

There’s a common popular science demonstration involving “soap boats,” in which liquid soap poured onto the surface of water creates a propulsive flow driven by gradients in surface tension. But it doesn’t last very long since the soapy surfactants rapidly saturate the water surface, eliminating that surface tension. Using ethanol to create similar “cocktail boats” can significantly extend the effect because the alcohol evaporates rather than saturating the water.

That simple classroom demonstration could also be used to propel tiny robotic devices across liquid surfaces to carry out various environmental or industrial tasks, according to a preprint posted to the physics arXiv. The authors also exploited the so-called “Cheerios effect” as a means of self-assembly to create clusters of tiny ethanol-powered robots.

As previously reported, those who love their Cheerios for breakfast are well acquainted with how those last few tasty little “O” s tend to clump together in the bowl: either drifting to the center or to the outer edges. The “Cheerios effect is found throughout nature, such as in grains of pollen (or, alternatively, mosquito eggs or beetles) floating on top of a pond; small coins floating in a bowl of water; or fire ants clumping together to form life-saving rafts during floods. A 2005 paper in the American Journal of Physics outlined the underlying physics, identifying the culprit as a combination of buoyancy, surface tension, and the so-called ” meniscus effect.”

On September 12 2024, Sam Altman, Chief Executive Officer of OpenAI, participated in a fireside chat for University of Michigans students, faculty and staff. The ChatGPT developer head spoke about the future of AI and its implications for education, as well as the challenges and opportunities presented by rapid technological advancements. Altman also shared insights into OpenAI’s new reasoning model, Strawberry, a model he describes as capable of complex reasoning and problem-solving.

“You all are going to create things that astonish us. The story of human history is that we build better tools, and then people do even more amazing stuff with them, and they themselves, you know, add their layer of scaffolding. And we’re on this steadily increasing curve of possibility.”
