Science - Maglev on existing tracks with no heavy magnets

Maybe this link has more technical aspects. I posted the other just
for information purposes.
Florida's first 'clean' hydrogen production plant is being built in Polk County

 

New portable system uses PV to produce drinkable water from air moisture

 

Sounds like they are using natural gas and “scrubbing” the carbon. I’m not sure what happens to the scrubbed carbon, and I wonder how efficient this whole process is.

Electric water heaters that store renewable energy could do the work of 2 million home batteries—and save billions

 

sounds like a penis brag

 

Me too, but I thought it took substantial energy to separate the hydrogen from water. Perhaps it’s easier to separate hydrogen from natural gas?

 

Hydrogen production - Wikipedia.

Steam methane reforming (SMR) is a method of producing hydrogen from natural gas, which is mostly methane (CH4). It is currently the cheapest source of industrial hydrogen. Nearly 50% of the world's hydrogen is being produced by this method.[9] The process consists of heating the gas to between 700–1,100 °C (1,292–2,012 °F) in the presence of steam and a nickel catalyst. The resulting endothermic reactionbreaks up the methane molecules and forms carbon monoxide and molecular hydrogen (H2).[10]

The carbon monoxide gas can then be passed with steam over iron oxide or other oxides and undergo a water-gas shift reaction to obtain further quantities of H2. The downside to this process is that its byproducts are major atmospheric release of CO2, CO and other greenhouse gases.[10] Depending on the quality of the feedstock (natural gas, naphtha, etc.), one ton of hydrogen produced will also produce 9 to 12 tons of CO2, a greenhouse gas that may be captured.[11]

 

And maybe the micro computer sees all movement orders as walk?

 

Maybe 5 to ten years but you aren’t wrong.

 

I would think the goal would be for it to recognize and enable each specific function. Otherwise, the patient couldn’t have any real fine/advanced motor skills, like climbing stairs, etc. I’m only assuming, though.

 

interesting.

That article had a couple of sentences poorly worded. This drug does not work on plaques.

Israeli scientists say they cured mice of Alzheimer’s using newly developed molecule | The Times of Israel


“We are taking a very different approach than efforts at Alzheimer’s medicines that we have seen so far,” Prof. Varda Shoshan-Barmatz, the lead author, told The Times of Israel. “Most are trying to address plaque that forms in the brain, but we are addressing dysfunction elsewhere.


Alzheimer’s research was set back many years maybe decades based on a prior study that associated amaloyd plaque reduction as the means of treatment, and the study was later found to be flawed. For many years after that study much of the work was done on plaques but it now seems like plaques may be a result, not the cause.

 

Having some AD trials for about 9 years I’d argue that Amyloid plaque plays a huge role. The question is what causes the normal shaped amyloid to change and form plaques.
The recently approved Biogen drug and the soon to be approved Lilly drug target the amyloid plaques have shown by removing the plaque disease progression is slowed by about 40% on average in some sub groups much more.
The trouble is there can be a bit of a wide range in the subjects some are much better to start than others and the cognitive testing can be a bit of a blunt instrument(they use a main end point of the CDR-sb). Having done over 1000 CDR exams on both normal and normal subjects the scale is designed to track decline and not really improvement.
We ran the biogen phase 3 trial and the Lilly phase 2 and phase 3 trial at our site. Had about 55 subjects combined on all three trials. The Lilly trial stacked the deck against themselves a bit as they not only required a Positive Amyloid PET scan but also a TAU PET scan showing some level of tau tangles (a finding associated with more advanced progression).

Currently we are running a Lilly trial with the same drug (Donanamab) subjects who are “normal” but at risk based on blood bio markers to be used as a “prevention”.

In general the people I see with lower amyloid levels and at higher function seem to do very well for sometimes years so it seems like the early intervention will likely have benefit.

 

Years, and the other thing is mice are close but not the same as humans as you can understand.
Mice that get AD have mostly been engineered to get the illness by knocking out certain genes, so the translation isn’t exact to humans as we don’t know all the factors that cause it in humans.

We ran a trial about 5 years ago for a company that in clinical trials had mice that were designed to have strokes, they had 100% recovery within a week of the “strokes”. It was a drug that increased neuroplasticity, inhuman trials we saw ZERO benefit, mind you the trial was only 6 months long and perhaps a longer trial would have shown benefits.

The really interesting way they measure mice “memory” is through maze trials and introducing new “toys”. Mice are very curious so when a new item is introduced they play with it for a time. It’s assumed that if they continue to play with the item they have forgotten it’s new.
Maze tests are self explanatory.

Not sure that completely translates to the human memory and thinking.

If true, that would be groundbreaking. I suspect it will take quite a while before it is affordable on a mass produced basis.
