David Reich – Why the Bronze Age was an inflection point in human evolution

Selection went especially bonkers during the Bronze Age (around 3,000 years ago). That's when gene frequencies for everything from immune function to body fat to intelligence were most in flux. Over the last 10,000 years, selection pushed the genetic predictor of cognitive performance up by roughly a full standard deviation — most of it between 4,000 and 2,000 years ago.

Venom and Hot Peppers Offer a Key to Killing Resistant Bacteria

Researchers have developed three new antibiotics from scorpion venom and habanero peppers to combat tuberculosis and other drug-resistant pathogens.

Embodiment and the (Re)invention of Emoji, from the Aztecs to Humboldt and Darwin to AI

The paradox of our time is that although we now know that consciousness itself is a full-body phenomenon, we have continued our campaign of denying the animal nature of the human animal by negating the significance, the relevance, the very fact of the body.

The Antimatter Road Trip Edition

Most objects we transport around the world tolerate their containers. They sit in them, press against them, get held by them. Even the most sensitive cargo, from organs to antiquities, vaccines to wild animals, exist in material continuity with the surrounding world. Antimatter is categorically other. It's not fragile in a way that patience and care can manage simply, because it's constitutively incompatible with everything that exists.

Michael Nielsen – How science actually progresses

Clearly human science is able to make progress faster than raw experimental falsification/verification would imply, and in cases where experiments are very ambiguous.

Terence Tao – Kepler, Newton, and the true nature of mathematical discovery

But the story of how we discovered the shape of our solar system shows how the verification loop for correct ideas can be decades (or even millennia) long. During this time, what we know today as the better theory can often actually make worse predictions (Copernicus's model of circular orbits around the sun was actually less accurate than Ptolemy's geocentric model).

Weekly Dose of Optimism #187

For every photon absorbed, the system produced 1.3 energy carriers. More out than in, which seems like it shouldn't happen.

AI Research Is Getting Harder to Separate From Geopolitics

A policy change announced by NeurIPS, the world's leading AI research conference, drew widespread backlash from Chinese researchers this week and then was quickly reversed.

A conversation with Claude

There could be more complex patterns in nature — too complex for a human to hold in their mind, or even notice in the first place, but stable and useful nonetheless. What if there are other complex-but-useful patterns in other domains, like materials science and biology? If they exist, I think AI will be able to find them and apply them.

Terence Tao – Kepler, Newton, and the true nature of mathematical discovery

During this time, what we know today as the better theory can often actually make worse predictions (Copernicus's model of circular orbits around the sun was actually less accurate than Ptolemy's geocentric model). And the reasons it survives this epistemic hell is some mixture of judgment and heuristics that we don't even understand well enough to actually articulate, much less codify into an RL loop.

Paleontologists Solve the Mystery of a Twisted Jawbone With Sideways Teeth

The jaw has this weird twist that drove us crazy trying to figure it out. We were scratching our heads over this for years, wondering if it was some kind of deformation. But at this point, we've got nine jaws from this animal, and they all have this twist, including the really, really well-preserved ones. So it's not a deformation, it's just the way the animal was made.
