If you ever wondered why visible light is those particular wavelengths, it's because life evolved to see in the narrow range where water is transparent

This is a bit of a parlor trick and is being hyped. The images are not being generated de-novo. They are being matched with a known set of prior images or text, meaning that they reconstruct the signals recorded by brain when shown images during training. Verrrry different than reading thoughts.

The postmenopausal ovary is often dismissed as a “shriveled husk.” A new Science perspective challenges that idea: the ovary keeps changing after reproduction ends. What it does in those decades deserves much more attention. www.science.org/doi/10.1126/...

Does the postmenopausal ovary still matter?
Ovaries may influence health long after their reproductive function ends

Putin's victory theory is to freeze Ukrainians, esp in Kyiv, over the winter in a gross violation of the Laws of War. Ukraine has generally been good about observing those laws. But at some point SHOULD it retaliate by taking out Moscow's power? It hasn't. But I bet it can. Should it? Real question

Michigan Law #MorningRead "Uncorrected." By Professor @nicholson.bsky.social and Janet Freilich in the Boston University Law Review. www.bu.edu/bulawreview/...
In addition to making rules and deciding outcomes, the legal system
generates, curates, and shares information. When the system gets rules and
outcomes wrong, it is obviously a problem, and much effort (and scholarly
attention) goes into identifying those mistakes and fixing them. But the system
also gets information wrong, a problem mostly overlooked by policymakers and
scholars. Those information mistakes matter too—they are prevalent and
harmful. We show here that even when the mistakes are widely known and the
errors broadly acknowledged, the information very often goes uncorrected. As
a result, people make decisions based on bad information from a system that
should be trustworthy and authoritative: builders build houses in mislabeled
floodplains, patients use medical devices that are not really safe and effective,
background checks disqualify potential employees based on crimes they did not
commit, and inventors rely on falsified data in patent disclosures, to name a few.
Why are so many legal information mistakes uncorrected? We identify
multiple reasons, including lack of support for public correction mechanisms,
lack of robust private mechanisms, challenges in communication between
institutions, and an overreliance on self-interest. An underlying problem,
though, is that information mistakes just are not given enough focus as the major
trans-substantive problem they are. That is its own mistake, because in a world
where an increasing number of decisions incorporate an increasing amount of
information, mistakes in that information matter more and more. Thankfully,
technology makes that task somewhat easier, as does increased attention toward
improving incentives and allocating responsibility. It is worth tackling the
