The quest to measure our relationship with nature

The United Nations is working on a Nature Relationship Index (NRI) to measure how well countries interact with the natural world. The NRI aims to shift the narrative from humans being destroyers of nature to fostering a green, abundant world. The index will assess three key questions: whether nature is thriving and accessible, if it is being used with care, and if it is safeguarded. The NRI will debut alongside the 2026 Human Development Report, encouraging countries to compete and improve their scores. The goal is to engage people's hopes and dreams for a better relationship with nature.

British cryptographer Adam Back is the secret creator of Bitcoin, claims new report — Back refutes investigation, says parallels to Satoshi are just a coincidence

A recent NYT investigation suggests British cryptographer Adam Back may be the secret creator of Bitcoin, challenging the long-standing mystery of Satoshi Nakamoto's identity. Back denies these claims, attributing the parallels to mere coincidence. The investigation delves into Back's involvement in the Cypherpunk movement, his creation of Hashcash, and his alignment with Satoshi's vision of a decentralized system. Despite linguistic similarities and career parallels, Back maintains he is not Satoshi, citing lack of knowledge about wallet addresses at the time. The article concludes with a potential slip-up in a hotel interview that hints at Back being Satoshi, though he denies it.
