#Shepherds, #lambs and #sheep
saradina-info-blog on 18.01.2026 um 09:01 (UTC)
 You often hear young people say they can't know this or that because it's "before their time."

This statement is often not without a touch of coquetry, since youth is a kind of modern-day badge of nobility—albeit a fleeting one.

Older people usually react with understanding, not without a certain reverence for the young life that has only existed for such a short time and therefore certainly doesn't need to know what happened before their own. These young people see themselves as lambs, pure and spotless, and free from all the vices of the past.

But as with every beautiful apple, there's a worm in it.

Aren't these young people like the lambs in a flock?

How glad the shepherd must be that today's lambs don't know that yesterday's sheep were sold to the butcher!
 

#Melatonin - a fountain of #youth?

 A long life. Many dream of it. But what good is a long lifespan if health and physical youth quickly fade?

There is an interesting clue from vegetable research on this topic.

Researchers injected melatonin into the stalk of an Asian cabbage variety.

This helped the cabbage stay fresh and last longer, much to the delight of greengrocers.

This effect was explained by the fact that melatonin slows down the metabolism and thus delays aging processes, so that the cabbage stays fresh and has a longer shelf life and can therefore be sold for a longer period.

Melatonin is a substance that also has an effect on humans.

This raises the question of whether regular melatonin supplementation also helps people stay fresh and vibrant for longer.

This is particularly interesting considering that melatonin production decreases, especially in older people.
 

#Human #hair - a unique feature in #biology
saradina-info-blog on 29.12.2025 um 09:54 (UTC)
 People see it as part of everyday life, a piece of daily routine.

Styling, cutting, and growing hair. Human hair is almost infinitely malleable.
The growth of human hair, especially head hair, is a uniquely human characteristic.

It can be cut very short and then grown back up to hip length. A similar pattern seems to apply to beard hair.

This is unique in the animal kingdom. There are animals with short fur (mostly in warmer regions) and animals with long and thick fur (mostly in colder regions).

Animals with short fur will never have long hair; a leopard doesn't need to go to the hairdresser.

On the other hand, one could cut a lion's mane short (if he would tolerate it), but after the haircut, the fur would grow back to its original length.
Hair growth in animals appears to be considerably more limited than hair growth in humans.

Only human hair has the ability to reach such an extreme length.
Thus, the length of human hair would be one of the unique biological characteristics, like, for example, walking upright.
Since the possibility of relatively extreme length growth of human hair is so unique on the one hand, and on the other hand offers no survival advantage in the wild, the question arises whether the relatively extreme length growth of hair is a biological trait that arose when humans diverged from other highly developed primates in the course of evolution?
 

#Advent Season - a #cultural #world
saradina-info-blog on 16.12.2025 um 08:59 (UTC)
 Lately, the use of the words Advent and Christmas is increasingly avoided during the Advent and Christmas season.

As if the terms Advent and Christmas were undesirable and unspeakable.

The process is gradual; there are no official regulations or prohibitions. But the terms Advent and Christmas are increasingly being replaced by meaningless, generic terms like "festival" or "holidays."

I too have been infected by this attitude - without thinking about what it means when terms are surreptitiously stigmatized away.

But these terms have meaning and refer to an entire cultural world. It's not simply a matter of avoiding terms – entire cultural worlds are being erased.

This shouldn't be happening.

Therefore, and in that spirit:

I wish everyone a happy Advent season.
 

#AI #Images - #Dreamlike #Creativity?
saradina-info-blog on 27.11.2025 um 09:03 (UTC)
 I am constantly amazed and captivated by the beautiful and surprising images that AI can generate through prompt input. The images are not only harmonious but often also unexpected.

This combination is reminiscent of the human capacity to create art through imagination.

The AI ​​simply recombines existing images and templates found online in a way that appeals to human viewers.

Even today, this recombining of existing images can result in bizarre details. For example, daffodils might sprout from a living room table, and a cat lying in wait outside a mouse hole might be simultaneously pierced by the bars of the cage separating it from the mouse hole.
Yet none of these errors in the AI-generated images seem out of place; nothing appears to disturb the serene idyll. Everything is correct, nothing is true. But how does this paradox arise?

We live in a time where AI systems are not only admired but viewed as a kind of intellectual authority, because AI supposedly unites all knowledge – from science and literature to art and music. AI is seen, in a sense, as a superior voice of human culture and science.

But appearances are deceiving. While human knowledge—and ignorance, as well as numerous misunderstandings—has developed over millennia in a constant interplay between humans, their environment, and nature, AI has no practical experience and, in a sense, starts from scratch with the current state of knowledge and culture, along with its current misunderstandings.
Our "today" is the informative zero hour of AI.

Moreover, the AI ​​has no sensory capabilities whatsoever. It is blind, deaf, unable to feel, touch, taste, or smell. In a figurative sense, it is severely disabled in multiple ways.
And yet, there is a commonality between the pseudo-creativity of AI and human mental activity: dreaming. When people dream, they create worlds that seem fantastical to themselves, which they perceive as absolute reality while asleep.

In doing so, dreamers recombine all sorts of experiences and perceptions from their own lives, from everyday occurrences and critical life events to banal film and television scenes. Everything merges into the dreamer's subjective world without being true in a general sense.

In fact, no dreaming person has ever experienced a real world that is identical to the dream world.

This is where it intersects with AI. Without ever having seen anything, it creates collages of image elements that it cannot see or perceive. And yet, it offers statistically generated random worlds that appear plausible to AI on a mathematical basis.

A fanciful dream world, so to speak. The only problem is that, in case of doubt, the AI ​​cannot distinguish which world is real.

 

Everyone wants to be #young – but nobody wants to be a #child
saradina-info-blog on 11.11.2025 um 09:06 (UTC)
 The older people get, the more many of them long to be young again.

But what does "young" even mean?
In a chat room, mainly attended by people over 50 years old, the conversation turned to the daughter of one of the chat participants, who was having a birthday. The young lady had just turned seventeen.

After the usual congratulations, the chat participants immediately began praising the advantages of youth, and some raved about how wonderful it would be to be seventeen again.
But other chat participants quickly chimed in with a contrary view. They said they definitely didn't want to be seventeen again. At that age, one is far too dependent (economically) and, above all, far too naive.
How many fatal mistakes they would have made at that age! And how detrimental those mistakes would have been to their lives today. To be seventeen again? No, never, not for anything.
But on the other hand, the physical advantages of youth have been brought into focus.

No pain when moving, no limitations in movement, no illnesses, and not least, an attractive appearance. Youth is indeed a desirable state.
And so the chat participants pondered a young, healthy state in which they would not be dependent on family, school, and vocational training, and also not so naive.

These thoughts led them to an ideal young age of around twenty-five. At this idyllic age, one enjoys all the physical advantages of youth without being too naive or too strongly influenced by authoritarian family ties and economic dependence.
Some of the chat participants held even more radical views: They wanted to combine the physical advantages of youth with their already acquired life experience.

In other words, new hardware combined with sophisticated software.

Interestingly, in the elaborate debate about the advantages of youth, one phase of life was conspicuously absent: childhood.

Yet childhood is the epitome of beauty, purity, and innocence! The learning capacity and physical agility of childhood are also proverbial.

Yet nobody wanted to be a child!

This raises an interesting question:

How unattractive is it to be a child? And what should we be thinking about about that?
