Well, at least in mices. Doesn't mean it works on us too, no? : >

Drug Reverses Age-Related Mental Decline Within Days

Sounds way too good to be true. But if it is... wow.

"“ISRIB’s extremely rapid effects show for the first time that a significant component of age-related cognitive losses may be caused by a kind of reversible physiological “blockage” rather than more permanent degradation,” said Susanna Rosi, PhD, Lewis and Ruth Cozen Chair II and professor in the departments of Neurological Surgery and of Physical Therapy and Rehabilitation Science."

if it works, even if only in mice, it fundamental changes what we thought we knew 'bout brain disorders, particular those linked to age.

HA! Good Fun!

I suddenly feel a lot smarter than I am! 🙃

 

Wait... 🤔

What it does suggest is that the process works, so it may just a matter of finding the right compound.

"mice lie and monkeys exaggerate."

is perhaps a bit more complicated than suggested, but is nevertheless an amazing bit o' news.

This is a bit bigger than my fridge magnets...

https://www.iter.org/mach/Magnets

 

Went looking for the rest after reading an article about the magnets used in Iter (a fusion reactor being built in France). It's presumably so strong it would be able to lift an airplane out of the ocean. Of course the BBC article didn't specify if they were talking about a Cessna or an Airbus 320.

Mind you, those big plasma chambers will need a lot of magnetism to keep the plasma contained.

What do you mean with rocky start? This was awesome. Nobody expected it'll get this far. They almost nailed it on the first try ever with something that was never tried before. Let them fix the engine issues and there we go. 

SN9 is already build, so the next test won't be far away off either. Super exciting.

 

/Edit: I'm browsing the news and ofc so many people are laughing and saying the mission is a failure ... completely missing the point of that test. Seeing this ignorance makes my blood boil, seriously. This test was a huge success. Except for the landing and the mid-flight engine failures, everything worked. The rocket took off, made it high, managed to flip itself to the side, glide down, get back up and slow down for the landing. I'm pretty sure the results would have been even better if the 3rd raptor would have kept working.

Falcon 9 crashed many times before they nailed the landing, and now everyone is taking for granted that we shoot rockets into space and have them come back to the landing pad completely unharmed. This is not something we're doing since ever, this is super fresh tech.

Hell, going by the speed of things, I'm very certain we'll see a perfect starship landing in the next couple months.

I feel the same. So many people thinking it was a failure. They will nail it soon and it will be a revolution. Starship is cheaper and carry much more. It will enable solar energy from space, bigger telescopes than James Webb, asteroid mining... and so on.

Dammit, I explained it to a friend and he still said it must have cost a lot of money to SpaceX. Come on, they probably predicted many failures just in case. They wouldn't bet on quick success.

The big question for me is whether commercial space exploration will have access to nuclear energy.

Not even ESA has that.
It may technically be possible but associated costs would be ruinous for commercial ventures.

Why not? Are not power plants commercial as well?

I'm the enemy, 'cause I like to think, I like to read. I'm into freedom of speech, and freedom of choice. I'm the kinda guy that likes to sit in a greasy spoon and wonder, "Gee, should I have the T-bone steak or the jumbo rack of barbecue ribs with the side-order of gravy fries?" I want high cholesterol! I wanna eat bacon, and butter, and buckets of cheese, okay?! I wanna smoke a Cuban cigar the size of Cincinnati in the non-smoking section! I wanna run naked through the street, with green Jell-O all over my body, reading Playboy magazine. Why? Because I suddenly may feel the need to, okay, pal? I've SEEN the future. Do you know what it is? It's a 47-year-old virgin sitting around in his beige pajamas, drinking a banana-broccoli shake, singing "I'm an Oscar Meyer Wiene"

Nuclear power in space has energy density as a major requirement while terrestrial plants don't. That means that all (?) space based nuclear reactors use highly enriched fuel, and highly enriched fuel == 'weapons grade' which is even more very tightly controlled than low enriched fuel. The Russian plants for example use 90-95% U235 in space, their ground equivalents use 3.5-5% enrichment.

^ Got scrubbed, by the way. Next try is today I guess. Last thing I heard, the weather report wasn't that great, though, so there is a good chance it won't happen today either.

Has this woman just invented the rocket that will take us to Mars?

Quote

Dr Ebrahimi's new concept performs much better than existing plasma thrusters in computer simulations - generating exhaust with velocities of hundreds of kilometres per second, 10 times faster than those of other thrusters.

Sounds cool. When can we get one?

After reading the article it seems that this is just an idea and nothing more?
