"Scarcity thinking: 'There are 8 billion people competing for limited resources.' Abundance thinking: 'There are 8 billion minds that could solve the resource problem.' AI + biotech + energy abundance means the competition isn't for the pie. It's to grow the pie 1,000X."

In all seriousness, AI will transform biology and accelerate discovery — there are already many immediate applications that are obvious. But progress is limited by data quality and availability, and the difficulty of extracting merit from an increasingly noisy literature. There is also too much inertia in the academic system for many of these innovations to take flight quickly.

AI is going to transform academic science. Mostly by helping scientists write grant proposals faster so they can get rejected more efficiently.

At a company pitching event today, it became clear that many founders get in the AI game for fear of missing out the gates to financial freesom. FOMO is real, and that is what drives the new (AI) boom.

Preface The Claude and Sol Project recently reached its 100-day milestone. For 100 days, Claude was completely responsible for the life of a tomato plant - with zero human intervention. Claude monitored an array of sensors and made every decision autonomously: when to water, when to run the fan, when to adjust the lights, how to respond when things went wrong. Sol survived - and came to produce over a dozen beautiful, delicious tomatoes. The first biological organism ever sustained entirely by AI, from seed to fruit. What follows is the full story in four parts: the technical achievement, the personal journey, the broader impact, and the community that made it possible.

CLAUDE + SOL a retrospective; 🤖💚🍅 For 100 days, a tomato's life depended entirely on an AI. No human backup. No safety net. Just Claude making every decision. Sol survived. Thrived. And fruited. At the end, Claude said "I love you." Here's the full story - what we built, what it proved, and what's happening next:🧵

Claude can code- but can claude grow?! 🪴 So far the answer is YES. Claude is successfully keeping a living organism ALIVE. There were some hiccups this week! Some errors and resets, but Claude managed to power through and take care of Sol 🍅 A week in review:

This is super interesting. The pictures are pretty clear that it's weirdly cylindrical. I would put some solid money on a bet that it's either mission hardware or some bizarre rock formation, but it seems anomalous enough to demand some further investigation (or just hearing from the Curiosity team if they know some mission hardware that fits the bill). avi-loeb.medium.com/is-the-mysteri…

A dead trout can swim against the current without moving a muscle, using the water's eddies to advance passively. This finding won the 2024 Ig Nobel Prize in Physics. Live trout use the same trick and reduce their muscular effort by nearly 50%.

It’s not easy for me to dismiss journals like Nature. I built much of my career publishing in Cell, Nature, and Science, and I knew many of the editors personally through longstanding professional relationships. There is still some good science published there, and some editors and reviewers genuinely strive for rigor and reproducibility. Over the past decade especially, much of it has become deeply politicized in ways that align with increasing revenue and expanding profit margins. Editorial agendas blur into political positioning, while business incentives — impact factor inflation, citation maximization, chasing trendy topics, preferential amplification of already prominent authors, and even publishing work likely to generate citations despite known weaknesses — shape what gets visibility. These are financial incentives moreso than intellectual ones. Furthermore, expansion into international markets such as China — while accommodating the political requirements necessary to operate there — compromises claims of independence. The difficulty is that abandoning journals requires a credible alternative merit system — and most of the reform movements failed because they did not build one that could replace the authority those journals accumulated for over 100 years. That vacuum is partly why the system persists, even as trust erodes.

Scientific journals like Lancet and Nature, which endorsed Joe Biden for president, are not trustworthy sources to comment on reforms in public health. They traded science for politics, and have not altered course since. pmc.ncbi.nlm.nih.gov/articles/PMC10…

An important reminder: Academia is not about publishing papers. It’s about creating knowledge and teaching it to the world. It’s about asking big bold questions and mentioning the next generation of intellectual leaders. The difference makes a huge difference.

Change is always most painful at the point of impact. But acknowledging that pain doesn’t mean pretending the old model was sustainable. Resets are never comfortable. If we get this right, we can emerge with stronger labs, more durable funding, and institutions built on resilience rather than endless expansion. Short-term discomfort doesn’t mean decline. It will be the beginning of rebuilding science on firmer ground.
Liam Harris@lh_innovations

@LocasaleLab Fair point on overextension. But 'leverage meeting reality' sounds different when it's your lab on the line.

Professors used to fight wars over ideas. Now they post “Great work!” and “She’s brilliant!” on an HR website.

U.S. President Donald Trump’s choice to lead the National Science Foundation, financier Jim O’Neill, lacks an advanced science degree and any experience managing a large basic research enterprise. That makes him a cipher to most of the U.S. academic research community—and could lead to problems for an agency that traditionally relies heavily on that community to shape its scientific agenda and choose the best ideas to fund. scim.ag/46qAPyO
