Ground squirrels reduce their metabolism during hibernation; could humans do it, too, with some genetic tweaks?
Hibernation is extremely complex – after all, it affects every cell in the body – and there are almost certainly multiple switches involved in the process. MIT neuroscience researcher Siniša Hrvatin has identified another brain region that seems to play a key role in the process. In a paper published earlier this year (but not yet peer-reviewed), he and his team targeted a region known as the preoptic area, which plays a key role in metabolism and temperature. By activating neurons in the preoptic area of hamsters, the researchers put them into torpor, lowering the animals’ body temperature to 15C.
The key would be whether this is possible in humans.
And, of course, whether revival can be timed and automated – or perhaps with robotic (AI) assistance…
Of course, science fiction has posited “sleeper ships” for decades now. The Songs of Distant Earth (Arthur C. Clarke, one of the “Big Three”) is probably the most well-known of the classic sleeper ship stories, but there are plenty of others to choose from…
Originally designed to operate for just one year around Mars, MAVEN’s mission was repeatedly extended, enabling the most extensive research into the workings of the Martian atmosphere ever attempted.
Thanks to MAVEN, we know how the Mars atmosphere has been eroded by solar wind over billions of years. Designed to work for a single year, it operated for over eleven years.
NASA’s plans for Mars sample return are effectively cancelled as part of a bill approved by the U.S. Congress, ending efforts to collect Perseverance rover samples that could contain evidence of alien life.
The researchers argue that “if” trees could be planted on Mars…
OK, just stop right there. I’m pretty sure Mars will struggle to support even grass, let alone trees.
And the argument that, due to a lack of oxygen, flammable wooden structures in space would not be in danger strikes me as a bit ludicrous…surely there would be oxygen inside the wooden structures?
And, you know, I do think I’ve seen this before some where…nah…
According to Thorne, who served as a consultant on the science of Interstellar, quantum mechanics could hypothetically explain a way to time travel via wormhole. So far, it’s a thought experiment that leads to the conclusion that you’d lose information along the way—not very practical.
First off, I’m incredibly annoyed at the way WordPress has screwed up the “quotation” function. It seems they are more focused on encouraging bloggers to use AI to write.
Uh. I don’t need AI. I blog. The end. WTH is the point of using AI to write my thoughts? It’s already being trained to USE my blog in the first place! Idiots.
OK. Second, the Popular Mechanics article I’m linking to is entitled “Interstellar travel is possible if we break into a higher dimension, scientists say.”
Only, that is NOT what scientists say. It’s still a thought experiment!
Using the new method, one metric tonne of lunar soil will be able to produce about 51 to 76 kilograms of water, equivalent to more than a hundred 500-millileter bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said.
The soil was from the 2020 expedition, which was the first in 44 years to bring back soil from the Moon.
Considering all of NASA’s problems, it looks like China will have a moon base years before the US does…and probably in prime resource locations as well.
And don’t forget that the hydrogen in the soil can also be used for rocket fuel. It would be a lot easier to launch ships to Mars and beyond without having to deal with Earth’s gravity…
My short story “Two Strikes Against” was selected as the Winner in the inaugural Next Generation Short Story Awards! (Official list to be available next week.) UPDATED: Link here https://shortstoryawards.com/winners.php?year=2024
Basically it’s a story about a Japanese baseball player on Mars, with a twist. It got rejected a couple of years ago by several scifi magazines, so I figured why not try the sports category.
Especially since there was no scifi category.
Just grateful and thankful for the award. I hope you all get a chance to read the story!
(FWIW “Marsball” is mentioned by characters in an early chapter of Bringer of Light. In fact, I was going to call the story that. Very glad that I didn’t in the end!)
