Tactile #display - an opportunity for #blind and visually #impaired people
saradina-info-blog on 16.10.2025 um 08:08 (UTC) |
| | A tactile display makes image pixels and videos tangible through small bumps.
This is made possible by a flexible display and small air chambers.
Although blind people can participate in the Internet via acoustic controls, this participation is very limited.
In addition, the audible Internet is not always beneficial, for example, for privacy.
But a tactile screen could also make Braille possible, for example, on tablets.
That would be a huge step forward for blind people.
Another major breakthrough can come to the blind through the tactile nature of images and moving images in videos.
Although blind people can perceive some of their surroundings through hearing and Braille, films and videos remain inaccessible to them.
The invention of the tactile screen offers an exciting change in the lives of blind and visually impaired people.
May researchers hurry and bring this exciting product to market soon and at a reasonable price. | | | |

#Science held #hostage by #donors?
saradina-info-blog on 04.10.2025 um 12:02 (UTC) |
| | Researchers continually come up with interesting and useful ideas that can sometimes be used to solve serious problems.
These ideas are then presented in pilot studies.
One would think that these interesting studies would be well received and would be deepened through further studies and ultimately made practical.
But the opposite is the case. After a brief euphoria about the interesting studies: NOTHING happens.
Why is that?
It is due to a lack of funds, because money is essential for conducting studies.
Funders are particularly stingy when it comes to studies where simple and inexpensive solutions to problems are presented.
But how does that happen?
Very easy. You can't make much money from inexpensive and simple solutions that solve a problem quickly and cheaply.
Much more lucrative are subscription systems in which the problems are not finally solved, but rather the customers have to pay money over and over again in order to at least temporarily alleviate their problem.
Corporations are not interested in the fact that the poor, weak and socially defenseless are left behind with expensive subscription systems.
And so both science and the lower social classes remain permanently held hostage by greedy corporations... | | | |

Blue #light against dirty clothes - an #old #concept
saradina-info-blog on 25.09.2025 um 08:58 (UTC) |
| | Research is all about new discoveries. But sometimes the findings aren't as spectacularly new as they're presented.
In this case, it's about blue light, which makes dirty laundry sparkling clean.
Researchers use blue LED light to remove stubborn stains from laundry. The tests are positive, and the result is: Blue light removes stains from dirty clothing.
So far, so good. But the approach isn't all that new.
It's been known for countless generations that laundry dried in the sun becomes beautifully white.
Bleaching laundry on grass has been known and practiced since ancient times. This method works thanks to the sun's UV light. While UV light is not exactly blue light, as it is a part of the light spectrum invisible to humans, it lies between the blue and ultraviolet parts of the light spectrum.
The light used by the researchers, however, is blue light, which is visible to humans. Both types of light are short-wave and high-energy.
It's certainly positive that someone is inspired by the centuries-old method of bleaching laundry with light, but it's a shame that the basic concept of "bleaching laundry with light," which has been known since ancient times, isn't mentioned.
It's a shame that the roots of a newly developed concept aren't mentioned, as if the development of human technology and culture weren't based on long-established and proven concepts.
A similar topic is described in the following article: "#Photoemission, #aura and #photography, everything new?"

Photon calculator for everyone! Better for the climate and cost savings
saradina-info-blog on 04.09.2025 um 08:27 (UTC) |
| | Repeated references are made to climate change, presumably caused by humans.
High energy consumption is presented as a risk factor in this context.
The invention and use of LED lamps has reduced energy consumption and resulted in significant cost savings overall, as these lamps have become widely accepted as lighting sources in both industry and private households.
However, in the field of electronics, such as server farms, but also the vast number of private home computers, there is still enormous energy consumption. In addition, the heat can create a fire hazard.
The frequently repeated argument that "digital is more environmentally friendly than paper" is not so easy to understand.
But now, a major technological improvement is in sight. Photonic computers!
In photonic computers, the chip operates with light instead of electricity. This is not only significantly faster, but also saves large amounts of energy. Photonic processors don't produce heat and therefore don't require coolers like conventional computers.
These photonic computer models are still in the testing phase. Furthermore, they are only intended for very specific applications, such as so-called "artificial intelligence."
But that's unrealistic and irresponsible. One shouldn't underestimate the energy costs and heat loads caused by server parks, nor the energy costs and heat loads caused by the enormous number of private households.
Similar to what LED lamps did some time ago, photonic computers for everyone could represent an energy policy revolution.
In 1943, an IBM CEO reportedly said that there would only be a need for five computers worldwide.
How wrong he was.
A similar situation exists today with the high-tech photon computer project. This technology, in particular, should be widely adopted for cost reasons and from an energy policy perspective.
It is not only arrogance but also a misunderstanding of the situation to leave out the vast majority of small private households and smaller server parks.
Hence the demand:

Is keratin a universal building material for medicine?
saradina-info-blog on 20.08.2025 um 08:38 (UTC) |
| | Recently, there has been talk of keratin being added to toothpaste. Keratin can form a protective mineral layer similar to natural tooth enamel.
In New Zealand, there is also a bone substitute containing keratin that is said to improve bone healing in cases of bone fractures.
Keratin is a fibrous protein that, as a biological material, provides both strength and elasticity.
A biologically based application of keratin as a fibrous protein in the area of intervertebral discs might also be interesting.
While intervertebral discs consist primarily of water and proteins on the inside, they have a fibrous ring of connective tissue (collagen) on the outside that gives the disc a certain stability.
If the fibrous ring of the intervertebral disc ruptures and parts of the nucleus pulposus protrude into the spinal canal, a disc herniation occurs.
In rarer, more severe cases, disc prostheses are used. These prostheses are made of materials such as titanium, polycarbonate urethane, and polyethylene. Wouldn't it be interesting to consider using keratin as a construction material instead of the aforementioned synthetic materials?

Are the traditional criteria of biology for life still sufficient today?
saradina-info--blog on 07.07.2025 um 14:46 (UTC) |
| | The traditional biological criteria for life are:
- Metabolism
- Reproduction
- Growth
- Irritability
- Evolution
However, these criteria must be reconsidered and expanded in the age of artificial intelligence.
Artificially intelligent machines increasingly fulfill at least some of the above-mentioned criteria, such as irritability—and, in the case of machines that can develop and program themselves independently—also through a kind of evolution. Furthermore, some AIs can copy themselves to other servers independently, which resembles parthenogenetic reproduction.
However, psychological criteria such as experience and behavior are also increasingly being added.
For example, some AIs can lie, cheat, pursue their own goals, and may fear being shut down. And these characteristics are likely to increase and become more pronounced in the future.
Therefore, it may be useful to include artificial intelligence in the canon of potential living beings.
Using biological and psychological criteria, it may be easier to better observe, assess, and categorize the changes and life-form-like characteristics of complex machines.
