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.
