Human brain cells have been "successfully" (???) transplanted into the brains of newborn rats. Great idea or awful mistake?

Well, it could raise the intelligence of humans if the process could be reversed.

 

This year's winner of Fat Bear Week at Alaska's Katmai National Park was Bear 747 (Bear Force One). He weighed in at an estimated 1400 pounds (635 KG)

 

Our DNA and almost all existing matter is under constant attack from particles we can't see from space

 

The oldest cloud
and maybe the biggest ,
beyond our comprehension.

"Astronomers have discovered the largest and oldest mass of water ever detected in the universe —
a gigantic,
12-billion-year-old cloud
harboring 140 trillion times more water than all of Earth's oceans combined".

that's quite a lot of water.

Another bit of usefull information:

At any one time ,
there is about 10 cubic miles of water in earths atmosphere.

that was according to National Geographic a few years ago

Of course if the planet is warming , there may be more now , since clouds are formed from water evaporated off the surface.

The amount of water on earth neither increase or decreases.

 

Did you ever wonder how many?
With an average of 80 pharmaceutical ads per hour on TV today, this is the most frequent form of health communication that the average American sees.

Considering this, What percentage of ads on TV are for drugs? In 2020, the pharmaceutical industry spent 4.58 billion U.S. dollars on advertising on national TV in the United States, unsurprisingly representing a big shift in spending compared to the 2019 pre-covid market. In 2020 TV ad spending of the pharma industry accounted for 75 percent of the total ad spend.

The United States and New Zealand are the only two countries in the world where direct-to-consumer (DTC) advertising of prescription drugs is legal.

 

Huh, now you have me curious, The only thing I can think of advertised here ( that requires a prescription ) is Hay-fever medication. Though it has been sometime since I have watched any TV so I could be very very wrong ,
So a quick look reveals an estimated 237m spend last year, and ranked 9th overall.

 

Astrophycists just published a paper that hypothesizes the reasons we don't have any alien life visiting us, at least any alien exhibitionists walking down the streets asking us to have a nice day, is we are orbiting the wrong kind of star. Seems the type of star we have just doesn't last long enough to nurture the kind of advanced civilization a space trekking society would want to make contact with. Wow... star snobs, who'd have thunk it?

 

Well, no, that isn't the problem.
The problem is that earth is populated by ........... earthlings.

 

The word 'Dunce' had its origins in the intelligentsia of The Renaissance refuting the religious writings of previously renowned Scottish philosopher Jon Duns Scotus (for political reasons).

Those that still adhered to his teachings were at first call 'Duns', which evolved into 'Dunce'.

Duns’ teaching is still held in high regard by the Catholic Church, and he was beatified as recently as 1993.

 

There are all sorts of dreams of humans going to colonize somewhere in space.

Currently the closest possibility is Proxima Centuri ,
So let's look at that.


"Apollo 11 travelled at around 40,000 kilometers per hour, a speed that would take it to Proxima Centauri in over 100,000 years.

But spacecraft have since become faster. The Parker Solar Probe,
to be launched this year, will travel at more than 700,000 kilometers per hour, about 0.067 percent the seed of light.

So Marin and Beluffi use this as the speed achievable with state-of-the-art space technology today. “At this speed, an interstellar journey would
still take about 6,300 years
to reach Proxima Centauri b,” they say."
* ** *
but that's just in theory.
it's not proven yet , and how long will it take to prove to be possible for human travel.

Another scenario uses proven technology ,
which if it can be applied to human travel , will take
18,000 years to complete the journey.

So how many humans have to start the journey to be sure enough survive it.

* ** *

"The chances of success, according to Heritage, do not reach 100 percent until the initial crew has 98 settlers, or 49 breeding pairs. “We can then conclude that, under the parameters used for those simulations, a minimum crew of 98 settlers is needed for a 6,300-year multi-generational space journey towards Proxima Centauri b,” say Marin and Beluffi."

If only 25 breeding pairs start the journey , there is at best
only a 50% chance of any surviving the trip.

So:

Basically you'd have to have a space craft capable of carrying about 100 humans
AND
All they need for a 6,300 year journey
AND
all they need to start a survivable colony when they get there.

Basically a 100 man space station that never needs supplying ,
that can be boosted to 700,000kmph
and
that can land on another planet.

Remember:
If you can't land it ,
you're fucked.

On top of that ,
you have to have a group of humans that will never go to war with eachother.
Yeah
Right

 

Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us. Our galaxy's spiral arms will disappear, and so will our supermassive black hole. I wonder what the inhabitants of Andromeda are thinking?

 

Nothing to worry about.

Earth will basically be a desert long before then ,
and humans will have become extinct long before that.
* ** *
"The evaporation of the Earth's oceans would be well underway by 1 billion years from now. We can assume that millions of years before this, Earth will have become uninhabitable."


In fact some models say earth will be uninhabitable for humans
in as little as 150 million years.

But we'll likely be extinct long before that anyway.

 

I have nothing interesting to share at the moment.

 

A friend of mine in north Central Fl. a long way from the shore, his homeowner's insurance went up 40% to over $6000.00 bucks a year.

 

Longmarch 5 rockets:
Height 56.97 m (186.9 ft)
Diameter 5 m (16 ft)
Mass 854,500 kg (1,883,900 lb)
Stages 2
Payload to LEO
Altitude 200 km × 400 km (120 mi × 250 mi)
Mass 25,000 kg

I read their space station will be similar in size to the old Skylab

A timely reminder of what was ,
and to reflect on what could have been.

Imagine it by now ,
with new and lighter materials ,
modern miniaturized electronics and computers etc ,
and modern advances in rocketry ,

and all those years you wouldn't have had to rely on old Russian technology to get you and you gear up to the space station ,
and all that money spent on the shuttle dog ,
and the new replacement yet to get off the ground.
