New research from UC San Diego and Princeton reveals the winning formula for climate action: carrot AND stick.
Their study shows that combining clean energy subsidies with pollution taxes drives faster adoption of green tech than either approach alone. Economic models prove this dual strategy can deliver rapid emissions cuts in the near term.

Proficiency-Aware Adaptation and Data Augmentation for Robust L2 ASR
General-purpose ASR underperforms for atypical speakers, such as L2 learners, reinforcing bias and limiting use in education and accessibility. Using the CEFR-graded Speak and Improve corpus, we show that naive fine-tuning of Whisper reduces average WER but simultaneously widens disparities and disproportionately harms lower-level learners. To address this, we propose two strategies: (i) proficiency-aware multitask learning, jointly optimizing ASR with proficiency classification, and (ii) targe…
