Elephants may be domesticating themselves

Summary: According to a study published in the Proceedings of the National Academy of Sciences, elephants may have domesticated themselves, making them the only known animal besides humans and bonobos to have done so. The study suggests that elephants' empathetic behavior, recognition of deceased elephants, and self-awareness may have evolved due to self-domestication, a phenomenon where wild animals develop traits similar to domesticated animals. However, proving self-domestication in any animal, let alone elephants, is a challenge. Richard Wrangham, a Harvard University primatologist, and evolutionary anthropologist Brian Hare of Duke University have long held that self-domestication must be widespread, found in numerous species from mice to whales and elephants.

Removing PGP from PyPI

Summary: PyPI, the Python Package Index, has announced that it will no longer support uploading PGP signatures alongside release artifacts due to long-standing issues with the approach used. While existing signatures will still be available, no new signatures will be made available, and related API fields such as has_sig will always be false. An examination of the signatures on PyPI revealed that only 36% of unique keys that had uploaded signatures to PyPI were capable of being meaningfully verified at the time of audit. The continued support of uploading PGP signatures to PyPI is no longer defensible, and while it doesn't represent a massive operational burden to continue to support it, it does require any new features that touch the storage of files to be made aware of and capable of handling these PGP signatures.
