This is the most detailed picture of a human cell ever made đź§Ş

Sam Bousaba on Instagram: "This is a single human cell. The white filament-like structures are microtubules, and the small colored particles are ribosomes. Your body contains on the order of ~37 trillion cells. Each cell functions like a highly organized, self-regulating factory operating continuously. There is no central “supervisor”—yet thousands of processes run in parallel with remarkable coordination. Every ribosome is constantly building proteins by linking amino acids together. In eukaryotic (human) cells, a ribosome typically adds about 5–10 amino acids per second (not ~20). Since a single cell can contain millions of ribosomes, protein production is massive—resulting in millions to tens of millions of peptide bonds formed per second per cell. The microtubules act as an internal transport network. Motor proteins such as kinesin move along these tracks, carrying cellular cargo. They “walk” step by step using ATP, at speeds of roughly 500–1000 nanometers per second. Each cell contains a dense network of these filaments, with many motor proteins moving simultaneously. Just beneath the cell membrane lies the actin cortex, a dynamic meshwork that helps maintain cell shape and resist mechanical stress. This structure is continuously remodeled—assembled and disassembled—allowing the cell to adapt to its environment. Now scale this up. Across ~37 trillion cells, each containing millions of ribosomes and hundreds to thousands of mitochondria, your body is constantly producing energy in the form of ATP. Total ATP turnover is enormous—roughly equivalent to your body weight in ATP recycled every day. The DNA in a single human cell, if stretched out, measures about 2 meters. Across all your cells, this would span distances comparable to traveling from Earth to the Sun and back many times (the exact multiple depends on assumptions about cell count and DNA packing). None of these processes are under conscious control. They began when you were a single cell and have continued uninterrupted ever since."

I keep seeing the "cars replaced horses" thing related to "AI."
People keep comparing "AI" to cars (positively) without thinking about the fact that cars were forced on people (AAA bought up and destroyed tram lines, there were massive protests, etc), and are the primary driver of climate change that is currently on track to make complex human society impossible. Meanwhile, cities that weren't destroyed for cars, or that have reversed most of the damage, are some of the most desirable places to live.
Maybe we could take the car analogy as a warning. Maybe it could be a reminder to think about how forcing technology on people against their will can reshape society in a profoundly negative way.
The answer for cities has been to right-size transit. Eliminate cars wherever possible, maintain emergency vehicles and mobility aids, and find more efficient alternatives (bikes, trams, metros, and trains) where possible. I feel as though we can extrapolate from the metaphor.
We do not have to repeat the mistake of reshaping society around a single, oversimplified, solution in order to benefit a tiny minority. Perhaps we can actually choose the right technologies based on use cases, rather than hype or dogma.
Cars didn't replace horses. Cars replaced walkable cities, tram lines and mass transit, and children playing in the streets.
"Cars replaced horses" to the benefit of a small group of elite men, at tremendous cost to literally everyone else. When people say, "AI is the new 'cars replacing horses'" they are saying something very specific about their privilege and intentions.

A UK MP reported a constituent to the police for the 'crime' of writing to him about #Gaza
What's worse, she was arrested at 04:33 -- which presumably means they went into her house in the middle of the night to arrest her. I've had this happen to me fifty years ago -- over a plan to ship schoolbooks to

Load break cutouts on a cross connect downtown

Utility pole with a single phase transformer and four cutout switches on it, all currently closed in.

The fuse cutout feeding the transformer is a standard one attached to a stirrup on the primary phase furthest from the camera.

The other three cutouts are fed from stirrups on the right side phases and drive the phases on the left side of the pole, but can be opened manually (or blow on overload) to isolate one side or the other in the event of a fault or for maintenance. These have larger gr…

Manchester United are playing extremely well under Carrick. Fernandes is deservedly the player of the season and he’s lifted them to a top 3 finish. Transcendent season from him.
But it’s also true that in their last three results (W-D-W), both wins were by a single goal and both game winning goals were handballs waved away by VAR. The goal against LFC I could understand. You could see the spin change, but it was less definitive. Today’s decision? Smells bad. Really bad.

Content warning: Minor spoilers for "A Psalm for the Wild-Built"

Just finished "A Psalm for the Wild-Built" by Becky Chambers. Overall it's good but I also have some Thoughts.
First, it was very pleasant to finally read some non-trite utopian solarpunk after having read stuff like Octavia Butler recently. Both hope and despair can be poisonous on their own IMO, so getting some balance in is nice. It's definitely a very valuable thing to be able to lay out an actually desirable and in many ways imaginable future given our grim present. Chambers is no LeGuin though. I'll probably be reading more of her work and maybe she fleshes out these ideas elsewhere, but at least in this book there is no focus on either how the transition to a better society could happen nor on how the better society holds up in the face of adverse events and inclinations. Compare LeGuin's "The Dispossessed" or N. K. Jemisin's short story "The Ones Who Stay and Fight" and it feels like there's something important missing from Chambers' portrait of a future society. Of course, maybe the point is to make a cozy book, in which case fine, there's certainly a place for such things, and I can look for deeper inspiration elsewhere.
The second big thought I had was that Chambers' worldview seems not well-informed by certain indigenous perspectives, and this creates some contradictions. For example, (minor spoilers) when Dex enters the wilderness there's a whole bit about understanding humankind's place in nature and how human settlements are what we're used to but they're only a brief interruption of the vast untouched wilderness. Along the same lines, much of the world is intentionally left untouched by humans as a way to keep it pristine and natural. Later however, a character makes the point that humans *are* animals. The indigenous perspective that I appreciate would agree with that, and would further question the value in distinguishing between human influence on ecosystems and influences that others have. More sharply, one might observe that there's a bigger difference between how different kinds of humans relate to and influence their environments than between how less-disruptive humans and various animals do the same: the strip-mine-operator vs. migrant tribesperson impact difference is probably much greater than the migrant tribesperson vs. beaver gap, for example. Rather than talking about limiting human disruption, then, as if all human-environment interactions are disruptive and must be minimized, we could/should be talking about how to create human societies that have beneficial relationships with their environments and acknowledging that we actually have many positive examples of that, both historical and contemporary. Chambers' utopia is a "humans dominate nature but restrain themselves so that their disruptions are minimal and thus nature can thrive" vision, but what I'd even more like to see would be a "humans study old ways and make new ones so that they can interact positively with ecosystems again" vision, including some of "here are the places that sometimes breaks down but also the patterns and institutions that ensure repair of those breakdowns and thus long-term sustainability."
Final big thought: Chambers' utopia is too homogenous for my tastes. Of course it's hard enough and valuable work dreaming up and sharing any utopia and Chambers' transcends triteness in a number of ways, so this criticism is a bit rude. But the single shared religion, lack of mention of conflicts around shared decisions, especially historical society-defining ones, and nagging questions like "what about the people indigenous to the now-uninhabited lands?" and "what about the indigenous peoples who weren't part of the factory-building societies?" leave me wishing for more nuance in this direction.
All in all: a good book, and I'm criticizing out of a place of appreciation, not scorn. I've got there sequel out from the library as well and will probably detour to a few other books but get to it pretty soon.
Sadly I don't remember who, but I got this one because of a recommendation on here, so thanks if you're someone who recommended it!

Just so you know, a T-Rex fossil is being auctioned off at Sotheby's today.
Just in case you have the spare cash.
And room in your yard or garage.

Now, I don't especially like the term "church" so I may use something else... like "coven." You can do what you want. But I happen to have already mapped out an example. (It is exactly that, just an example, so take if it's useful, change if you need, and don't stick to anything too closely.) Oh, this mapping also means that you would, for religious reasons, only be allowed to work under capitalism 4 days a week instead of 5.
Given the increases in productivity over the last 100 years, a 4 day work week is a completely reasonable expectation. If we have to annex Monday for the weekend by force of religion, so be it. It is rightfully ours anyway. If enough people try it, this will probably work. If it doesn't work, it just needs more people.
The Practice of Worship:
It is recommended to break down worship in to three sections: the functional, the communal, and the spiritual. It is also recommended to break these across multiple days. A common structure for some Christian churches is to take 10-15 minutes for announcements (Functional), an hour or two for services (Spiritual), followed by (Communal) coffee, tea, and cookies for an unspecified time up to two hours after. When starting or working with limited time a single compressed model like this may work, but it's not optimal.
- The Functional
The purpose of this section is to address the functional needs of the coven. Block out time (less than 90 minute blocks is recommended) to go through reports and updates from those involved in the Dispensary, Library, Works Committee (infrastructure), and Services Committee (providing services internally and, potentially, externally). Talk through any additional announcements, including those from other covens you may be federated with.
It is helpful to include unstructured communal time, such as shared meals, during or after functional meetings. As the federation grows, more time will be needed. It is recommended to break functional meetings, work parties, and such across multiple days. When a federation becomes sufficiently large, it is recommended to take every Monday, on top of Saturday and Sunday, as a third day of community and worship.
The scope of the functional spans 3 realms (which may be more-or-less fluid): the personal or family, the coven and federation, and humanity itself. It is up to each coven and individual to negotiate how to allocate the three days of the weekend once we have liberated Monday from the work week, but it is important to reserve it for one of these three. However, some people must work on weekends. Medical personnel, for example, cannot conform to a standard work week. While the work week should be universally restricted, which specific days are used will be up to the specific coven and their members.
A functional meeting can start with an agenda like the following:
Functional Invocation
Announcements
Report Backs
Dispensary
Inventory Check
What is low
What is empty
What is expiring
What is needed
Funds status
Library
Inventory Check and Items needing return
Library acquisition requests
Funds status and budget check
Works Committee
Upcoming projects
Subcommittee updates (Following the Works Committee agenda)
New committee formations
Funds status
Services Committee
New capabilities announcements
New needs requests
Subcommittee updates (Following the Works Committee agenda)
New committee formations
Funds status
Task Check
Breaking the Circle
This agenda is a suggestion for those who don't know where to start. It can be adapted or ignored as appropriate.
- The Spiritual
Spirituality is necessarily an undefined space. It is deeply personal. Each individual taking time to share their own personal spiritual experiences can help each connect with each other. This experience of connection can itself be a spiritual experience. It may also be useful to read esoteric, mystical, or philosophical texts together as type of "book club" and share thoughts. Others may draw from their own knowledge or traditions. This is something that must be defined together within a group.
- The Communal
The communal aspect of the practice of worship bind the coven and federation together. Within the community we find joy and release, connection and comfort. The coven is where we turn in times of need, and where we share our hopes and dreams.
