You might kill AI progress by something you are doing, or rather not doing. Nameley, to pay for it.

Scientists have come up with a new way to look for alien life by proposing a measure of complexity

Humans dominate the planet because of their ability to quickly adapt by learning rather than natural selection. The downside is that we quickly become blind to change. The world is changing extremely rapidly at the moment and it will get wilder. Don't get blind to it.

AI progress per dollar of investment shows diminishing returns (as we've all known, right?) This is using METR's estimate of acceleration at Anthropic. That acceleration isn't enough to overcome the diminishing returns. by @sebkrier

We’re sharing new research demonstrating how AI agents can accelerate the science of stress-testing encryption.
Guided by humans, our models uncovered two major weaknesses in legacy 1024-bit RSA cryptosystems.

Across our projects @GoogleDeepMind, we are witnessing a genuine phase transition in the pace of scientific discovery. You will see a glimpse of this in our releases in the next few weeks.

Excited to see that the Aaronson-Ambainis conjecture has apparently been proved! But depressed to see the amount of completely incorrect commentary on its implications, so here's an attempt to clear things up.
A decade old anomaly in particle physics refuses to go away and gets stronger instead.

If this proof holds, it means that quantum computers are only polynomially faster than classical computers for general problems. Shor's algorithm is an exception, not the rule.
Today Physical Superintelligence PBC is announcing a proof of the Aaronson-Ambainis conjecture, one of the central open problems in quantum complexity, with major implications for quantum computing speedup.

This is really cool: a magnetic eddy current demo makes a quartz wristwatch run faster.

Slow status of fusion startups with dim update about @Helion_Energy “Understood physics is slow. Poorly understood physics is fast right up to the point you understand it”

AI is creating fabrications in scientific papers
A random sample of 500,000 peer-reviewed journal papers found that fabricated references rose from 6.3 per 10,000 in 2023 to 23.0 per 10,000 in the first quarter of 2026 (with no signs of abating).
This is going to create a challenge for journals to catch these errors and hold authors accountable when they submit work with serious flaws.

Nuclear fusion startups are postponing and postponing their completion dates. Especially Silicon Valley's favorite startup, Helion, has received some heavy criticism lately.
A group of physicists say they have figured out why our universe exists.
