00:42 < Ashstar> it would be great to see the ages pass as we gain wisdom, to be a part of history, to live 100's of yers
00:42 < Ashstar> years
00:44 < Ashstar> yet though, as I reflect as a biologist, is that right? Why has life built in time limits?
00:46 < Ashstar> why do cells experience apostosis
00:47 < Ashstar> if all of us lived hundreds of years, then how would that affect the availability of resources
00:48 < Ashstar> qui pro bono?
00:48 < Ashstar> just a thought

00:57 < Ashstar> are we the part of life's relay team? Do we live to pass on what we have? the wisdom, the collected resources to open doors?
00:59 < Ashstar> sequence?
00:59 < Ashstar> Research suggests that 'time cells' – neurons in the hippocampus thought to represent temporal information – could be the glue that sticks our memories together in the right sequence so that we can properly recall the correct order in which things happened.

01:00 < Ashstar> lol
01:00 < Ashstar> sory
01:00 < Ashstar> Evidence for these kinds of sequence-tracking time cells has previously been found in rats, where specific neuron assemblies are thought to support the recollection of events and the planning of action sequences.
01:00 < Ashstar> But for a long time, less was known about how episodic memory is encoded in the human brain.
01:00 < Ashstar> To investigate, a team of researchers led by neuroscientist Leila Reddy from the Brain and Cognition Research Center (CerCo) in France monitored electrical activity in the brains of 15 epilepsy patients, using microelectrodes implanted in the hippocampus.
01:01 < Ashstar> "Given the importance of the hippocampus in sequence order learning and temporal order judgments, we tested whether human hippocampal neurons represented temporal information while participants learned the order of a sequence of items."
01:03 < Ashstar> During the sessions, the electrodes recorded specific neurons in the hippocampus firing in response to the experiment, both during specific moments as images were displayed, during gaps when no images were shown, and at pauses where participants were asked to predict what image would be shown next from a sequence already displayed.
01:03 < Ashstar> According to the researchers, the neurons involved are evidence of time cells: "neurons whose activity is modulated by temporal context within a well-defined time window".

01:14 < nsh> .gpt4 what are gate cells in the context of network zeitgeiber theories of circadian rhythms especially within the SCN?
01:15 < gptpaste> ​The term "gate cells" is not a standard term widely recognized in the context of circadian rhythms or the suprachiasmatic nucleus (SCN), which is often referred to as the master clock of mammalian timekeeping. However, based on your question, it seems you are referring to a concept related to how signals might be gated or modulated within the SCN or other parts of the brain - https://bin.gy/cericiotio

04:24 < docl> time tracking is a valid neurological function, doesn't mean we have to die. sheesh. and evolution doesn't literally philosophize about limits to growth
04:25 < docl> if it could make people live up to infinity years evolution would think that's great. it just can't quite figure out how
04:28 < docl> probably something more like having cells predictably lose function after the organism has had a chance to reproduce squares better lower hanging with cancer prevention strategies like having cells less easily able to reproduce unlimited numbers

10:52 < AugustaAva> ​It will be interesting to see what happens if DOD gets serious about L2. Congress recommends ensuring "the United States is the first country to permanently station assets at all Lagrange Points." <arstechnica.com/space/2023/12/… https://t.co/fy2rhEIlHX> ]
10:53 < nsh> presumably if states start asploding each other's lagrange point 'assets' there won't be as much of a debris problem as in earth orbit
10:53 < nsh> not great to be trying to dominate them though. some kinda antarctica/lunar arrangement should be arrived at

11:13 < fenn> you're 50 years late, congress
11:14 < fenn> lagrange "points" are way harder to clean up because there's no air resistance slowly removing debris
11:14 < fenn> (they're orbits, and while the relative velocity would be lower, it would still cause cascading increases in debris if left unchecked)
11:16 < L29Ah> zero-g assetium mining operations
11:18 < nsh> at L4,L5 you would expect to see stable corotating clouds (modulo any external influences of mutual interactions due as a result of collisions due to initial momentum from disintegration events) 
11:18 < fenn> same deal with the recent push for nuclear thermal rockets, it no longer makes sense when it costs far more to build each reactor vs just launching chemical propellants
11:18 < nsh> at L1,L2,L3 without station-keeping the orbits are not stable and decay away from the points
11:19 < nsh> *or
11:19 < nsh> it might be possible to design solar sails to sweep things up but dunno without thinking about the materials science
11:20 < nsh> or lasers 
11:20 < nsh> everything can be solved with big enough lasers
11:21 < nsh> or you can yeet little thrusters at things that adhere maybe
11:21 < fenn> lasers, yeah
11:21 < nsh> i'm vaguely optimistic that the problem becomes solvable along the same rough trajectory of development that it becomes more likely

11:22 < fenn> it's still a lot harder to clean up with lasers than LEO because you have to fully "deorbit" them by turning it into a ball of assetium, rather than just giving it a nudge and letting air resistance take over

11:31 < fenn> i dunno maybe the relative velocity is low enough to catch debris with nets or aerogel
11:34 < fenn> i see the artemis accords as a first step to enclosing the lunar commons, by creating "safety zones" which are really just a euphemism for territory
11:34 < fenn> and that kinda came out of nowhere, without any public discussion
11:35 < fenn> democracy, yay
11:36 < fenn> antarctica is an even worse model, it essentially amounts to "don't do anything, and nobody else is allowed to do anything either"
