ISS study suggests that weightlessness impacts the eyes of men more than women
Astronauts who experienced changes in their
eyes (SANS) while on long missions in space
The uncertainty of science: A recent study of 30 astronauts during long term stays on ISS suggests that weightlessness impacts the shape of the eyes more in men than in women.

In addition to changes in fluid around the brain, the team also found that a form of eye compression, a hallmark of Spaceflight Associated Neuro-ocular Syndrome known as globe flattening, was the most consistent eye change among crew members. “By far the most prevalent sign of eye changes that we observed was globe flattening, suggesting that this should be the primary monitoring target for ocular health,” Seidler said. “Interestingly, eye changes were more prevalent in males than females.”
Globe flattening, when the back of the eyeball becomes slightly indented or pushed inward, might sound minor, but it can have significant effects on vision and raise concerns for long-duration space missions.
Surprisingly, there was no strong link between brain structural changes and eye changes, suggesting that the effects on the eyes and brain may arise from distinct mechanisms rather than shared physiological cause
For the eye research, the sample was so small, 28 individuals of which only 9 were females, the researchers readily admit in their abstract that and “interpretation of these findings should be tempered by the fact that our sample included a relatively small number of females.” Nonetheless, the research did suggest that, regardless of sex, about half of all humans will experience these eye issues during long missions in weightlessness.
The results underscore the need to do artificial gravity experiments in orbit, to find out the minimum amount of gravity needed to mitigate or even eliminate these health issues. Otherwise, interplanetary travel is going to be seriously hampered, if not impossible.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I await the study where the statistics tell the story between the dangers or benefits of when a woman becomes pregnant in zero gravity and when a trans woman becomes pregnant in zero gravity.
I suppose we will have to wait for the next Democrat administration for that study.
Speaking of such silliness:
SCAREY AND FUNNY AS HELL
https://www.sigma3ioc.com/post/scarey-and-funny-as-hell
One of the big differences between the Left and the Right in politics is that the Left because of the dark desperate place they must exist in have no sense of humor. And those on the Right especially under the guidance and leadership of today’s president who is a mixture of Ronald Reagan, Rodney Dangerfield and George Washington are self-deprecating and have a sense of humor.
Recently there was a meme made where J.D. Vance was made into an insane looking curly haired maniac, and J.D. portrayed his meme on Halloween. No biggie, just having fun and frustrating the Left at the same time. Those on the Left are so invested in being so moralistic and so outraged and put out that they no longer have any semblance of a sense of humor, if they had one at all to begin with.
This meme war was really set of most recently when the president himself pumped out into the webesphere this hilarious Mexican themed meme mocking and nailing both Senator Charles Schumer and Congressman Hakeen Jefferies to their desperate attempt at securing their human capital investment in the millions of illegals they ushered into OUR country for their political power consolidation strategy reasons.
Charles Schumer and Hakeem Jefferies memed by the president himself: https://youtu.be/PBa-UZ3-lvg?si=6so0Vom_bjIf_9L4
Remember: Politics and government are not about truth and morality; they are about political power and control. And when politicians and government tell you how moral and truthful they are you know they are lying and are attempting a bait and switch on the public to further secure their political power.
That being said, in this political warfare that the people watch to determine who in some great measure is telling them some measure of truth in order that they are able to direct THEIR country those who are able to keep a sense of humor are usually who is the more truthful, self-reflective and interested in fundamental American values.
When will the Democrats on the now desperate, extreme radical Socialist Left regain some measure of humor? Not any time soon, by my calculations this curly haired insane looking meme maniac will be the next president of the United States. And the Rights trend of national political dominance will continue from today for the next 23 years, 1 month and 29 days at least.
And why is that? Because those on the Right have retained a sense of humor and are not desperate in their seeking to wrestle and or steal political power from the people who direct them.

Just remember the Reagan blanket amnesty—long before Biden.
I remember hearing Pat Buchanan brag about how the GOP accused Daley about police brutality.
He should have had his back—that was the last chance mainstream democrats had to save the party from its current fate.
Cotour,
Humor does not advance the people’s revolution, comrade. Just more bourgeois self-indulgence.
Jeff Wright,
We remember the Reagan amnesty. It was a mistake because it simply set up the expectation of future amnesties and did nothing to discourage illegal immigration – quite the contrary.
I suppose that my humor was an example of the bourgeois mocking itself and all who oppose it / them? I am a member, although a lower party member.
Some further comments on humans, their eyeballs and everything else human in space:
The human animal is of the earth, and the earth is unarguably an exceptionally by all measures and observations a special location within OUR solar system at the minimum and may well be unique in the universe.
The earth for a series of very almost unfathomable reasons occupies a position in this solar system that expresses an extreme penchant for producing life in a multitude of forms and potentials, human beings at the moment occupying the highest level of technological ability to manipulate matter, understand where that matter comes from and generally how it relates to that expression of life and its potential.
Any animal which there are millions of variations of the earth for the last say 3 billion or so years with the exception possibly to some degree of the Tardigrade is eternally wed to the gravity well and the unique peculiarities of the earth which has been a wet planet for the majority of its existence concerning the existence of life.
Most planets in this solar system are either much too cold or much too hot and have atmospheres much too harsh to reasonably consider the existence of any kind of significant life to exist, In my possibly too naive opinion of course. Life of consequence possibly could have existed previously (?), but it appears to be undetectable right now at this point in our human explorations in space and through the many very fine examples of high technology conceived and manufactured to date that look for it.
Human beings being of the earth as they are formulated right now are not built for long periods of time in zero gravity or less than earth’s gravity nor are they conditioned to productively or reproductively exist for very long periods of time off earth without either becoming chronically ill physically and or mentally.
The time and unimaginable distances between planets not to mention the stars, not to mention the galaxies represents a natural barrier to exploring and establishing long term human living situations IMO.
Unless there are Star Trek level technologies developed (and I am not discounting that potential) where there are realized effective artificial gravity technology and a way to effectively create a barrier to radiation powered by a source of energy that I in my naivete do not see existing at this moment in time human beings unless a way to interdimensionally (?) travel will be limited to our local situation, the moon and Mars for limited periods of time lest you / they seek death, insanity or both.
And again, I stress my naivete on much of this subject, but the evidence appears to more support my position than others who would absolutely disagree who might find themselves reading this on BTB. But that is just me.
