- 1Brain entropy during psychedelic trips linked to lasting well-being gains●Brain entropy during a psychedelic trip tracks later gains in insight and well-being https://www. psypost.org/brain-entr
New research reported by PsyPost suggests that levels of brain entropy measured while a person is under the influence of a psychedelic drug can predict how much insight and improvement in well-being they experience afterwards. The finding adds to growing scientific interest in how psychedelics affect brain dynamics and could help explain why some sessions produce lasting psychological benefits.
- 2Octavia Butler's Earthseed debate finds new readers●“I still can’t see change or entropy as God,” Travis said, bringing the conversation back to Earthseed. “Then show me a
Readers are sharing a passage from Octavia E. Butler's Parable of the Sower in which the character Lauren, founder of the fictional Earthseed religion, defends her belief that God is change. In the exchange, Lauren challenges the idea that change and entropy cannot be divine, asking what power could be more pervasive. The quote is circulating among book discussion groups, with Butler's work drawing continued attention in science fiction and bookloving communities.

A new essay argues that evolution runs counter to entropy's reputation as pure destruction, suggesting that life and increasing complexity are natural outcomes within an entropic universe. The piece contends that the universe builds structure rather than only breaking it down, framing biological complexity as part of thermodynamic processes rather than an exception to them.
- 4Seed Phrases Are Just 128 Bits With a Checksum▼If you have ever set up a self-custody crypto wallet, you have seen it: a screen with 12 or 24 plain... # blockchain # s
A technical write-up is making the rounds explaining how BIP-39 seed phrases actually work: the 12 or 24 words shown when setting up a self-custody crypto wallet encode just 128 bits of entropy plus a checksum. The piece walks through the mechanics behind the mnemonic standard that secures most crypto wallets, prompting discussion about how such a small amount of data underpins billions in digital assets.
- 5Entropy and time debated in physics-themed post●Time is just entropy in motion. No circumstance, just physics. Build systems that resist the decay. klytron.com # physic
A claim circulating online argues that time is nothing more than entropy in motion, and that circumstance and fate are reducible to physics. The message urges people to 'build systems that resist the decay', tying thermodynamic thinking to engineering and resilience. It promotes klytron.com and carries physics, entropy, cosmos and thermodynamics hashtags.
- 6Netflix password rule bans the tilde character●This dumb password rule is from Netflix. [The help page]( https:// help.netflix.com/de/node/54078 ) and the [password re
Netflix's own help and password reset pages state that passwords must be between 4 and 60 characters and may not contain a tilde (~). Security commentators are highlighting the requirement as an example of arbitrary, poorly justified password restrictions that reduce entropy without improving security, reviving broader debate over outdated password policies at major companies.
- 7High-entropy molecular contacts boost perovskite solar cell efficiency▼High-entropy molecular contacts enable high-efficiency and stable perovskite solar cells
Researchers report in Nature that using high-entropy molecular contacts at the interfaces of perovskite solar cells delivers both high power-conversion efficiency and improved long-term stability, addressing the durability problems that have limited the technology. The finding is drawing attention as a step toward commercialising perovskite photovoltaics.
