Can language models perform end-to-end scientific discovery? In our NeurIPS Spotlight paper, we show: very rarely. Our best model found <20% of discoveries, our best PhDs found nearly all. Paper: Code/Web: @allen_ai @MSFTResearch

A reduction of almost 75% (330k -> 90k) of NSF-funded scientific staff. For every ~10 PhD students funded in 2024, only ~3 would be funded in 2026. Source (page 22, summary tables 6):
The US government is aiming to get rid of a quarter million people involved in science research and education by 2026. I have no words.

25 years ago, when he was a week into his professorship and I was a week into my undergraduate, I asked some very naive questions in one of his seminars on quantum computing that he very patiently and encouragingly answered. I remember that kindness to this day.
Raymond Laflamme 1960-2025. A great scientist, renowned for his pioneering contributions to quantum error correction. A great leader, founding director of @QuantumIQC. A great colleague and teacher whose legacy continues to inspire us.
