- Comment on Most Astronauts Get ‘Space Headaches.’ Scientists Want to Know Why 8 months ago:
They mention this in the article, but the physiology would suggest this is related to CSF/blood pooling in low G.
Taking it a step further, I bet this has a similar mechanism to IIH or the high pressure headaches you get with obstructive hydrocephalus. CSF is supposed to drain down via a relatively passive system. Without G to regulate this I can envision that you’d essentially develop the same physiology as someone with IIH (too much CSF).
Really interesting. A good example of how we have no idea what insane health things we are going to experience with space travel, but also how space travel may shed insight on treatments for other conditions with similar mechanisms we experience in a gravity well.

That makes more sense then. Still would need a house, but could manage that with planning/tiny home over time.
- Comment on Why don't we hear more about the 2017 Las Vegas shooting? It was the deadliest mass shooting in U.S. history, we never found a motive, and it seems no one ever mentions it. 8 months ago:
I mean, reading the Wikipedia article is seems like there’s a lot known about the killer and a pretty clear motive of him wanting to kill a bunch of people…
- Comment on Why don't we hear more about the 2017 Las Vegas shooting? It was the deadliest mass shooting in U.S. history, we never found a motive, and it seems no one ever mentions it. 8 months ago:
Something about the Vegas one (other than total number of fatalities) was so much more sinister. We barely even ever heard about the perpetrator. It’s always seemed bizarre to me.
Not saying we should be giving any media attention to mass killers, but it definitely breaks with the normal media portrayal.

How are you going to buy a bunch of land with a small amount of UBI?
- Comment on [deleted] 8 months ago:
I’ve been saying this for a while, and that’s why I think a complex problem like this needs a more complex solution than UBI.
Essentially I think successful UBI would need to be something like UBS instead (Universal Basic Support). Instead of only being money it needs to consist of free services. That way it’s harder for third parties to leech it away.
So instead of “Here’s $1000 a month, do whatever you want” it would need to be more like “You can get free healthcare here, free electricity through this company, free food rations from this grocery store.” Then if you want things above UBS you need to have some source of income.

The internet is such a funny place.
Open Lemmy and see this on the front page today with a ton of upvotes, yet I make a post a while back criticizing Boomers and my account gets brigaded and spammed. Hope that’s not happening to you OP!
Lemmy is almost as toxic as Reddit these days.
- Comment on SpaceX is reportedly building a $1.8 billion network of spy satellites for US intelligence 8 months ago:
Having mega corporations design space networks for you sounds like a great idea until they decide to lock you out and hold your government hostage. Or sell intel… Or sell access to other actors….
Just admit it—the corporations run the world at this point.

🤣
- Comment on Lemmy Active Users looking good 8 months ago:
Yep. Been saying for a while that it feels like old Reddit.
I wonder if it’s a nerd-level thing. Reddit devolved as it turned into another social media outlet instead of a niche internet techie place.
- Comment on I’d rather stay up anyway 8 months ago:
Think of your sleep as reading a series of engaging books, where each book represents a sleep cycle, including chapters of both deep sleep (SWS) and dream sleep (REM). When you finish a book (sleep cycle), you reach a satisfying conclusion to that story arc—this is akin to waking up after a full sleep cycle. You feel refreshed because you’ve concluded the narrative neatly, without interrupting a tense plot twist or leaving a storyline unresolved.
However, just finishing one book doesn’t mean you’ve completed the whole series. If you stop after one book each night, you’re missing out on the depth and development that comes from reading more of the series (accumulating more sleep cycles). Initially, you might feel okay because you’ve concluded a story (cycle) properly, avoiding the grogginess of waking up mid-chapter (mid-cycle). Yet, this approach doesn’t give you the full, enriching experience (or rest) your body and brain need over time.
As days go on, if you continue this pattern, you accumulate a ‘reading debt’—akin to sleep debt. You’ve missed out on the broader, deeper insights and the full narrative arc that only comes from reading (sleeping) the whole series or book. This debt reflects not fully recharging your brain and body, leaving you progressively more tired. While you might feel a temporary refreshment from completing a cycle, without the full, restorative rest of multiple cycles, you’re not truly at 100%—you’re running on the satisfaction of a finished story, not the full restoration that comes from a complete series.
- Comment on I’d rather stay up anyway 8 months ago:
Yeah, it’s about getting enough REM and SWS cycles. The effect decays over time, though. If you time your wake up to a full sleep cycle (around 2.5-3 hours) one night, you may wake up feeling fine. If you do this multiple nights in a row, however, you will build up a REM/SWS debt. So on day one it feels fine, on day two it feels less fine, and on day three you’re dragging.

Can this please be marked as some sort of spoiler? I haven’t watched Picard Season 3 yet and this was a massive spoiler bait title…
- Comment on Young adults set an earlier bedtime as they navigate economic fatigue, wellness trends, and a loneliness epidemic 9 months ago:
That’s a good point. I have found that post-pandemic people seem to also be a lot more accustomed to canceling last minute. I almost have more success having semi-large work gatherings than small friend ones.
- Comment on Young adults set an earlier bedtime as they navigate economic fatigue, wellness trends, and a loneliness epidemic 9 months ago:
I love how I’ve been seeing more and more of these articles, and in ways they seem accusatory of GenZ/Millenials for not consuming.
I’d like to believe that just as much of folks not going out is them realizing from the pandemic that they don’t need to do it to be happy, as it is that they don’t have the money to go out. Just don’t do it. Have a close group of friends you enjoy. Don’t shell out money to poison your mind/body. There can be an upside to this.
- Comment on Is the bot/troll situation getting worse? 9 months ago:
Yeah, I think there’s a handful of toxic folks on here who are behind the bots or a series or alt accounts. I think Reddit probably had more infrastructure in place to crack down on stuff like that, but it’s happened to me (although less dramatically) in other threads here as well. But yeah, there’s no way my relatively normal comment got immediately downvote spammed and commented on by 6 different accounts. Definitely alts.
- Comment on Is the bot/troll situation getting worse? 9 months ago:
Totally true. I made a totally reasonable comment about a month ago (stated that women shouldn’t be hit on at the gym by randos), and I got downvoted to oblivion and the comment was spammed by 7 different users who essentially acted like I was Hitler. Then they started spamming my comment history and I had to delete all of my old posts.
Seemed like a real person was behind it, but may have been using bots to spam me.
- Comment on ‘Don’t Mess With Us’: WebMD Parent Company Demands Return to Office in Bizarre Video 10 months ago:
Yeah, so the decision is actually counter to the evidence.
- Comment on ‘Don’t Mess With Us’: WebMD Parent Company Demands Return to Office in Bizarre Video 10 months ago:
I’m so sick and god damned tired of corporations and governments making sweeping decisions with no evidence base to back them up. I work in a field where there is no option for remote work, but I think it’s pretty clear at this point that most non-service industries can be just as effective via remote options. All of this is just about control and it’s so stupid.

Agree. It was fun to hear. The bit around 37 mins about what it’s like being dead was fun
- Comment on Six months after the initial reddit surge (graphs) 10 months ago:
I’ve tried to go back to Reddit here or there, and I literally can’t do it. I only visit it for very select communities that don’t exist here.
The post frequency isn’t the same here, but the quality of the posts and the comments is so much higher. I’ve said this before, but current Lemmy reminds me of Reddit in the early 2010’s before it got shitty. One of the great things about early Reddit was that it was more mature, people tended to assume good intentions more often, and it promoted logical dialogue. That has VERY MUCH been lost in Reddit’s current incarnation.
