Dartmouth researchers trained an AI language-identification model inspired by Google Translate to recognize Navajo with near-perfect accuracy using a data set of 10,000 sentences. They also found that widely spoken languages like Navajo may serve as a bridge to "teaching" translation tools related languages that have less data available. The study suggests that online translators such as Translate—which does not currently support any Native American language—can be expanded to identify Navajo and related languages relatively easily. The team presented their work at the Nations of the Americas Chapter of the Association for Computational Linguistics (NAACL) conference in Albuquerque. 

The global climate is in an imbalance. Potential "tipping elements " include the Greenland ice sheet, coral reefs, and the Amazon rainforest. Together they form a network that can collapse if just one individual component tips. Researchers from Bonn University Hospital (UKB) and the University of Bonn have now shed light on seemingly sudden and rare, often irreversible changes within a system, such as those that can be observed in the climate, the economy, social networks or even the human brain. They took a closer look at extreme events such as epileptic seizures. Their aim was to better understand the mechanisms underlying such changes in order to ultimately make predictions. The results of their work have now been published in the journal "Physical Review Research".

Concerns over health and freshness are keeping many shoppers from embracing frozen foods, a new study suggests - despite their potential to reduce food waste, cut carbon footprints, and offer affordable nutrition.

The research, published in the British Food Journal, explores why consumer resistance to frozen food remains stubbornly high, even as global demand for sustainable and convenient food options grows. The study found that anxieties around nutritional quality and freshness fuel health concerns, which in turn drive resistance to buying frozen products.

Is the role of “hotel manager” still needed in the hospitality sector? This is the central question behind a new study from the University of Surrey.  

Chatbots are getting better at holding conversations — but can they offer meaningful support in a therapy setting? A new study by USC researchers suggests that large language models (LLMs) such as ChatGPT still fall short when it comes to the nuances of human connection
