They accidentally invented a system for a battery to last 400 times longer

This research could lead to long-lasting batteries, with a life cycle 400 times longer than normal. And the most curious thing: it was thanks to a chance.

Throughout history, there are cases of inventions that have emerged almost from the rebound. The stainless steel is an example that illustrates well this type of providential accidents. When the British Harry Brearley strolled in the early twentieth century through his laboratory, among the samples of discarded metal alloys over months, he found a jewel in the middle of that cemetery of frustrating experiments. One of the mixtures had stood the test of time without rusting. It was stainless steel. Something similar has happened with this research on batteries.

Brearley sought to create more robust steel for the interior of the canyons. The problem they had was that over time the material deteriorated and they were unusable to shoot. The metallurgist and specialist in the production of steel were over 40 years old when performing these experiments. In principle, he had discarded the sample that would eventually become stainless steel because he considered it too weak. It was not until months later that he rescued her from the storage room to continue investigating her composition.

In this case, it is a team of scientists from the University of California at Irvine, who have created a new system called to form the basis of a battery. The objective was to develop a battery that instead of using liquid used a gel as an electrolyte, in this way the danger of catching fire is significantly reduced, as has sometimes happened with those of lithium-ion. In addition, it would prevent it from getting too hot.

For this, they used gold nanowires. However, instead of the intended objective, they realized that the system could be charged virtually unlimited times, at least compared to what we are used to seeing in current lithium-ion technology. The system maintained its efficiency after 200,000 charge cycles, a figure that far exceeds the life of any current electronic device, be it a smartphone, computer or electric car.
In comparison, a lithium-ion battery maintains its efficiency up to 5,000 or 6,000 life cycles. Scientists cannot explain why their system is able to endure so much. When they tested their development they realized that he had great resilience. Coated with a thin layer of a gel, it could perform thousands of loading and unloading cycles without losing capacity.

Scientists appreciate the value of this finding, although it is true that it remains to be known how this system could be scaled to work on a real battery. Apart from this challenge, development has another burden. Gold is an expensive material, so reaching a mass production would not be easy or, of course, cheap.

Artificial intelligence only artificial or artificial, can technology be creative?

When I hear the word art, works like “The Water Lilies” by Monet, “The Guernica” by Picasso and “The Starry Night” by Van Gogh come to mind. But there are also other great artists with not-so-well-known names, and it is that even some spots on a canvas can convey emotion, history, and culture.
Art is not just painting, it is also poetry, theater, novels, music, fashion, and cinema. All these art forms lead creators, pioneers, and innovators. But are they all human? In this blog we ask ourselves what it takes to be creative and if this creativity can reach the machines.
Creativity is defined as the ability to go beyond traditional ideas, rules, patterns, and relationships to create meaningful new forms, methods, and interpretations. Daniel Kahneman’s in his book “Thinking Fast and Slow” explores a human decision model in which he differentiates two systems: system 1 and system 2. While system 1 is impulsive and automatic, based on evolutionary instincts and tendencies, system 2 is logical and analytical.

A creativity study
A study by Jonathan Smallwood proves that more creative people are able to leverage both systems to create creative connections. These people can be simultaneously in a dream state and concentrated in the outside world. While imagination (system 1) is important to generate unique ideas, logical thinking (system 2) is necessary to exploit them. The machines have the tools to make a very precise analysis and logical connections, but can they dream? That is more questionable.

From composing music to building sculptures, AI systems in art feed on data from thousands of examples and look for patterns and trends from machine learning. With all this, the system is able to replicate and create similar versions. If we talk about creativity simply as something that goes beyond rules and patterns to create interpretations, could we not say that this is what the machines are doing? In one of our previous posts, we talked about how companies incorporate AI in many of their creative processes.
IA, the great imitator
Although what we like about an artist is their unique and recognizable style, we value machines more for their ability to copy and imitate. Well, any originality that can come out of them is merely a coincidence.

“It’s easy for AI to create something innovative randomly. But it is very difficult to create something innovative that is both unpredictable and useful. “- John Smith, Image and Multimedia Manager at IBM Research.
Remember that artists are inspired by external stimuli, events, and relationships, this is the same as Artificial Intelligence does with data inputs. We know that AI is not a pioneer in creating innovative content, but does this mean that it does not show creativity?

The argument of whether AI can become the next Picasso depends on the way we see creativity if we see it as a processor as a means to create something interesting. Many will see a beautiful piece of art and remain happy, but for others, creativity is a process that consists of moving away from what has already been done before. The machines will be really creative when they decide to start drawing without any previous instructions, but to think that this can happen becomes scary.

AI in art is currently a tool to help create work in a faster way. It is clear that we can teach artificial intelligence how to be creative, but it remains to be seen if it is capable of creating something exceptionally beautiful. The real creativity comes when you are surrounded by senses, feelings, and experiences, we experience something that only humans. We would have to incorporate everything we perceive as a human into machines; smells, sounds, feelings, connections, etc. so that they could become artists in all their essence.

Saturn, the king of the moons

The sixth planet in the solar system surpasses Jupiter with 20 new moons.
In 2006 the world of astronomy underwent an important change since the dwarf planet Pluto lost the category of the planet and instead had the category of plutoid.

Thirteen years have passed since that great change occurred when it came to having a conception of the solar system so far.

Whenever we studied our solar system, Jupiter was the largest planet in the world and the one with the most moons with a total of 79 moons. But it has been discovered that there is a planet that surpasses it in moons, and that planet is Saturn.

The new moons of Saturn
Saturn now has 82 natural satellites. Some of the new ones have a diameter that oscillates 3 and 4 kilometers.

Another fact to keep in mind is that of the 20 new moons, three move in the same direction as the rotation of Saturn, and the remaining 17 moons move in the opposite direction to the rotation of the ringed planet.

Of these 20 moons, two of them are close to the planet and take two years to complete the planet, while the remaining 17 moons are far from the planet and complete around in three years. Seen in Hawaii
This new finding has been thanks to the work of researcher Scott S. Sheppard and astronomers David Jewitt, of the University of California at Los Angeles, and Jan Kleyna, of the University of Hawaii.

The observations of these 20 new Saturn satellites have been made with the Subaru telescope, which is located on the summit of Mauna Kea, in Hawaii (USA).

To achieve such a discovery, an algorithm was used to check whether these celestial bodies fit or not to the orbit of this planet. It is possible to say that with this algorithm 12 moons were discovered that are part of the orbit of Jupiter.
