This paper from Harvard and MIT quietly answers the most important AI question nobody benchmarks properly: Can LLMs actually discover science, or are they just good at talking about it? The paper is called “Evaluating Large Language Models in Scientific Discovery”, and instead of asking models trivia questions, it tests something much harder: Can models form hypotheses, design experiments, interpret results, and update beliefs like real scientists? Here’s what the authors did differently 👇 • They evaluate LLMs across the full discovery loop hypothesis → experiment → observation → revision • Tasks span biology, chemistry, and physics, not toy puzzles • Models must work with incomplete data, noisy results, and false leads • Success is measured by scientific progress, not fluency or confidence What they found is sobering. LLMs are decent at suggesting hypotheses, but brittle at everything that follows. ✓ They overfit to surface patterns ✓ They struggle to abandon bad hypotheses even when evidence contradicts them ✓ They confuse correlation for causation ✓ They hallucinate explanations when experiments fail ✓ They optimize for plausibility, not truth Most striking result: `High benchmark scores do not correlate with scientific discovery ability.` Some top models that dominate standard reasoning tests completely fail when forced to run iterative experiments and update theories. Why this matters: Real science is not one-shot reasoning. It’s feedback, failure, revision, and restraint. LLMs today: • Talk like scientists • Write like scientists • But don’t think like scientists yet The paper’s core takeaway: Scientific intelligence is not language intelligence. It requires memory, hypothesis tracking, causal reasoning, and the ability to say “I was wrong.” Until models can reliably do that, claims about “AI scientists” are mostly premature. This paper doesn’t hype AI. It defines the gap we still need to close. And that’s exactly why it’s important.

This is a worthwhile and wonky read on some of the potential (existential) impacts to the FDA based on recent events

@LizzyLaw_ Interesting that AI in devices seems directly targeted. Any sense for whether the impacted people were involved in Neuralink interactions?

50% of scientists stop publishing within a decade of starting their career. A recent study looked at the careers of 140,000 scientist and concluded that less than half were still publishing 15 years later.

I had this exact experience. Our automated rent increase put us over the available open unit down the hall. We asked them to match, they said they were not allowed to, so we moved units for a lower rent, and even got a new tenant incentive on top (gift card).

Housing by algorithm is so much nonsense. I'm experiencing it directly in a way I hadn't known about before. My apartment building uses one of these legal price-fixing algorithms. Our lease is up soon and we saw that identical units to ours were going for much cheaper than what

Does astrology work? We tested the ability of 152 astrologers to see if they could demonstrate genuine astrological skill. Here is how the study was designed and what we found (including a result that really surprised me): 🧵

SCOTUS decision is very significant for FDA. Courts will continue to defer to FDA on product-review decisions, where Congress gave FDA discretion to make fact-based decisions based on careful process often outlined in guidance. But we'll see material changes in other areas 1/n
