Every query typed into a large language model (LLM), such as ChatGPT, requires energy and produces CO₂ emissions. Emissions, however, depend on the model, the subject matter, and the user. Researchers have now compared 14 models and found that complex answers cause more emissions than simple answers, and that models that provide more accurate answers produce more emissions. Users can, however, to an extent, control the amount of CO₂ emissions caused by AI by adjusting their personal use of the technology, the researchers said. 

To find the best catalyst for green ammonia, researchers were staring down 8000 lab experiments. With AI, they only needed 28.

A new study from the University of British Columbia has found that offering people a tiny chance to win a big cash prize can dramatically increase how many bottles they recycle. Instead of giving everyone a guaranteed 10-cent refund per bottle, researchers tested a new idea: What if people had a 0.01 per cent chance to win $1,000 for each bottle they returned? The result? People recycled 47 per cent more bottles.

MIT researchers discovered the underlying cause of position bias, a phenomenon that causes large language models to overemphasize the beginning or end of a document or conversation, while neglecting the middle. They built a theoretical framework that can be used to diagnose and correct position bias in future model designs, leading to more accurate, reliable AI agents.

A low-cost, scalable fabrication technology developed at MIT can integrate fast, efficient gallium nitride transistors onto a standard silicon chip, which could boost the performance of electronic chips used in high-bandwidth applications like video calling and real-time deep learning.

The University of Texas Health Science Center at San Antonio (UT Health San Antonio) was awarded nearly $3.4 million from the Cancer Prevention and Research Institute of Texas (CPRIT), to target hard-to-treat cancers with technologies not currently available in the state and boosting vaccination rates for the human papillomavirus (HPV) that leads to cancer.
