News item on digital technology

What an attractive idea!


This article tells us about new magnetic chips which could mean future computers. The most astonishing is that they use a millionth of the energy which chips need today.
It also tells us that this new technology has been shown that magnetic chips can operate with the lowest level of energy dissipation possible under laws of physics, it means a huge saving of energy.
It also mentions that for the first time, the “Landauer limit” has been demonstrated experimentally since it was argued in 1961 by an IBM researcher.
However, it will take a long time before the technology will be able to put into practical production.
In addition this news article explains us what is magnetic computing.
So, it tells that the new kind of computing uses tiny magnetic bars, instead of conventional transistors which rely on the movement of electrons to switch between zeros and ones. In conventional computing takes a lot of energy.

Another amazing datum is that each bit is a tiny bar magnet only 90 nanometres long.

This article is really interesting because we have discovered a new technology that will allow us to use the processing part of every machine which uses electronic stuff like chips with the minimum energy possible. It means that we would have lot of energy that we could use for another sectors and for sure the bills will low the pay.



The biggest challenge in designing computers and, in fact, all our electronics today is reducing their energy consumption. Making transistors go faster was requiring too much energy, the chips were getting so hot that they would melt

The wars are avoidable

Since the first men who lived on the Earth until today, there have always been wars and fighting among themselves. For example, the prehistoric men fighting to ensure his cave and defend their families. This is repeated until the time in which we live today.
To begin with, humans have an animal instinct that promotes greed and selfishness; dominant characteristics that have corrupted the coexistence among societies. When in the majority of civilizations it seems that you can live in peace and happiness, because of a few who want more power, it triggers an upset in several civilizations. In the event that these have enough strength and grudge accumulated, will face against aggressors and will begin a conflict that may end up in war; and so on.
As I said, the wars will always be present among humans because we have corrupt instincts stronger than the desire to reach a State of peaceful coexistence and fair for everyone.

Bionic Fingertip


This news article explains about how a bionic fingertip helps an amputee sense different textures. This article tells us about a man who lost his left hand, is now able to feel surfaces with his new prosthetic digit. He is called Dennis Aabo Sorensen and he suffered a firework accident nine years ago so he lost his left hand.
Thanks to this technological advance, this bionic finger allows him to feel rough and smooth textures.
It also explains how the bionic finger works, it is made of silicone and in the silicone are electronic sensors. These sensors detect the texture and sends nerve signals, using a computer "algorithm", to the brain.

Mr. Sorensen said the sensation is the same that he felt with his finger before the accident.


I found this as an amazing technologic development because now people who has lost their hands or feeds can feel the same that they could feel before they lost their extremities.
If science carries on with this velocity, might be that we could see disabled people walking again.


The bionic fingertip aims to replicate the sophisticated sense of touch in the human finger by using sensors (pictured) that detect minute changes in a silicon 'skin', transmitting these as tiny electrical signals

Can technology make a better world?

Technology has been able to develop mankind in an exceptional increase during the last 30 years. From Paleolithic period, our ancestors used tools made of sharp stones or arrows made of wood. They used them to make it easier to get food or face predators. So we followed the same way of development making computers, mobile phones, TV… These tools help us in our society to cover the needs we have. Nowadays there are several discussions about: what is technology really providing for the world? Many countries from Africa, Asia and South America are getting exploded to make some people richer than they already are. So, on one hand the modern world takes advantage of the technological advance, and many get rich. However, on the other hand many suffer terrible working conditions with ridiculously low pay.
Adding to that, many people, specifically young people, are getting hooked on these technologies which are addictive and they use all their free time looking at screens and not interacting with friends face to face.
With all this stuff between us, some creepy people use social media to get the life privacy of the others.
The technology advances have caused the corruption of the deepest and darkest feelings of humans: the wars. We have improved the weapons only to defeat other humans in the wars.
Yet, we have recently used the technologies to avoid potential coming wars.
In spite of these negative consequences, technology is making amazing discoveries and we have achieved memorable goals such as landing on the moon or go deeper on the knowledge about the behavior of the universe. Thanks to new technologies, we are able to communicate to each other whenever we want and independent of the distance the two people are separated.

So I can conclude that technologies help a lot the world to improve and move forward, but for every advance we do, there are negative consequences for our society and it makes us ask ourselves if technologies can really help and make the world better.

The Greenhouse

With regard to the serious problem posed by the greenhouse effect that is changing dramatically and ecosystems by altering the atmospheric phenomena on the planet, we should take steps to control it. It is true that it has been warning in all countries of the consequences which can cause this phenomenon. It must be said, however, that the greenhouse effect is just an acceleration and enhancement of a natural effect of the protection of the Earth that helps to maintain the temperature about 15 °C on average.
First of all we should stop using fossil fuels, such as oil and charcoal, and appeal more to the production of renewable energy such as wind, hydraulic, solar, etc.
After I boost the use of electric cars and, in relation to the population, I boost campaigns to reduce pollution and I notify of the risks involved in the continuous emission of polluting gases into the atmosphere such as the CH4, SO2, SO3, NO2, etc.
Eventually I would establish laws to control emissions of polluting gases of the factories with the aim of achieving a great decrease in emissions, because the industries are the main focus of emissions of gases causing the greenhouse effect.

Finally, it must be said that the planet is in a critical condition and if we do not react in time and do not take appropriate measures to reduce the greenhouse effect, everyone will suffer the consequences for the same.
