I’ve only noticed this in the past few days. Not sure if it’s a new issue, but I feel I wasn’t getting this before last week. (Eta: I’m on the latest update) Most Lemmy image links in comments are doing this now.

Sorry if it’s been posted already; I tried searching and didn’t see anything.

Thank you for all your hard work – I LOVE Voyager! ❤️

Becoming an astronaut is a fairly romanticized career path, but there are a lot of less-than-romantic aspects to working 50 miles or more above the Earth’s surface. Case in point: just being in zero G makes the human body do all sorts of embarrassing things.

A new story from the New York Times exhaustedly points out that living in space comes with all sorts of “bodily indignities” which should give even the most eager potential space explorer pause. It turns out, it’s not just deadly radiation or muscle loss due to weightlessness astronauts traveling to spots in our own solar system will have to put with:

In microgravity, however, the blood volume above your neck will most likely still be too high, at least for a while. This can affect the eyes and optic nerves, sometimes causing permanent vision problems for astronauts who stay in space for months, a condition called spaceflight-associated neuro-ocular syndrome. It also causes fluid to accumulate in nearby tissues, giving you a puffy face and congested sinuses. As with a bad cold, the process inhibits nerve endings in the nasal passages, meaning you can’t smell or taste very well. (The nose plays an important role in taste.) The I.S.S. galley is often stocked with wasabi and hot sauce.

These sensory deficits can be helpful in some respects, though, because the I.S.S. tends to smell like body odor or farts. You can’t shower, and microgravity prevents digestive gases from rising out of the stew of other juices in your stomach and intestines, making it hard to belch without barfing. Because the gas must exit somehow, the frequency and volume (metric and decibel) of flatulence increases.

Other metabolic processes are similarly disturbed. Urine adheres to the bladder wall rather than collecting at the base, where the growing pressure of liquid above the urethra usually alerts us when the organ is two-thirds full. “Thus, the bladder may reach maximum capacity before an urge is felt, at which point urination may happen suddenly and spontaneously,” according to “A Review of Challenges & Opportunities: Variable and Partial Gravity for Human Habitats in L.E.O.,” or low Earth orbit. This is a report that came out last year from the authors Ronke Olabisi, an associate professor of biomedical engineering at the University of California, Irvine, and Mae Jemison, a retired NASA astronaut. Sometimes the bladder fills but doesn’t empty, and astronauts need to catheterize themselves.

Link to study paper: Nonclassical Advantage in Metrology Established via Quantum Simulations of Hypothetical Closed Timelike Curves

Abstract:

We construct a metrology experiment in which the metrologist can sometimes amend the input state by simulating a closed timelike curve, a worldline that travels backward in time. The existence of closed timelike curves is hypothetical. Nevertheless, they can be simulated probabilistically by quantum-teleportation circuits. We leverage such simulations to pinpoint a counterintuitive nonclassical advantage achievable with entanglement. Our experiment echoes a common information-processing task: A metrologist must prepare probes to input into an unknown quantum interaction. The goal is to infer as much information per probe as possible. If the input is optimal, the information gained per probe can exceed any value achievable classically. The problem is that, only after the interaction does the metrologist learn which input would have been optimal. The metrologist can attempt to change the input by effectively teleporting the optimal input back in time, via entanglement manipulation. The effective time travel sometimes fails but ensures that, summed over trials, the metrologist’s winnings are positive. Our Gedankenexperiment demonstrates that entanglement can generate operational advantages forbidden in classical chronology-respecting theories.

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics.

We are not proposing a time travel machine, but rather a deep dive into the fundamentals of quantum mechanics. – David Arvidsson-Shukur

I’ve searched every way I can think of and can’t find anything.

I remember it played a nursery rhyme like a music box when both armrests were gripped.

That’s my sister and I visiting my great-grandmother in her infirmary in *1975. The chair wasn’t meant for visitors, but for children housed in the infirmary.

The chair had metal armrests that acted like actuators, and a metal box under the seat that played nursery rhyme songs like a music box when both armrests were gripped and the chair rocked.

Was this a common thing, perhaps mass-produced, or just something jerry-rigged by some guy?

Have you seen anything like this? Thanks!

(Sorry for reposting; my post went wrong last time.)

Self-explanatory, I think. I miss being able to flag users in Res – I usually used it to mark known trolls or experts in a subject so I could easily see them in threads. I sometimes used it to mark people who were especially witty or the like.

I think it was all client-side, because I had to import/export when changing clients.

It greatly contributed to my overall experience, and I think it would be a very valuable addition to Voyager.

Thank you, you’re awesome! ❤️

This report on experiments into time travel and extra sensory perception during the 1960s and 70s deserves a read.

It relates to non-physical time travel which, after years of research, I’m personally leaning towards as far as feasibility.

Assuming time is a separate dimension from the 0th-3rd, we wouldn’t be able to move in it in the third dimension (the physical) any more than we can physically move with our bodies in the 1st or 2nd.

If consciousness can move in higher dimensions, though (and we know it does, because it moves in time every moment; that’s how we perceive time), it isn’t constrained to the third like our bodies are. We already move through time, so the task would be moving consciously instead of being dragged along.

This may all be pseudoscientific bullshit, but if we can find empirical ways to test these hypotheses, I believe it’s worth exploring.

I’ve tried several Lemmy apps for iOS, and just switched to Voyager based on a recommendation here.

Oh my god, it’s fantastic!

I was a loyal Apollo user from beta till the enshittification, and your app makes me feel like I’m home again. It’s beautiful, has the features I so loved, and then some.

Thank you for your hard work and attention to detail. I love your icon/logo, too. You’re the best! <3 <3 <3

e: the only thing I don’t see is the Tip Jar. Am I just missing it?

Shortly after this picture was taken, we were on a float with my mother for the bicentennial parade. She made both our outfits of a (very itchy) polyester gabardine, and she wore a dress to match.

The apples my sister is holding meant something, but I don’t remember what and now I can’t ask her. I’d be very interested if anyone knows the significance of the apples during the US bicentennial.

I was 5 and my sister was 3.
