China has discovered a new mineral on the Moon. It’s so fluorescent it could change the way we make LED light bulbs

So far, 11 unique minerals have been discovered on the Moon. The last of them has just been revealed by a team of Chinese scientists after analyzing a lunar meteorite. It is an interesting finding, because it gives us useful information about the geology of our satellite. But also because it could have very interesting applications here on Earth. From the Moon to your light bulbs. The material just described It is cerium-magnesium changesite. It is characterized by its glassy, ​​transparent and brittle appearance. The thickness of its granules ranges from 3 to 25 micrometers, less than that of a human hair. Still, it is extremely useful due to its pronounced fluorescence, which could be very useful in improving terrestrial LED technology. A necessary color change. Unlike traditional incandescent bulbs, LED bulbs do not use heat to produce light. They make the most of electricity thanks to a semiconductor material, which allows the flow of electrons from a layer with an excess charge to another with a lack of it. That second layer has what are known as voids. That is, atoms that have lost electrons, leaving something like a free hole. The moment an electron encounters one of these holes, falls inside, in a process in which energy is released in the form of light. The light obtained in this process is blue, but we have all seen that, in general, the light from LEDs is white. The color change is achieved thanks to the coating the bluish chip in which the process occurs with a fluorescent material. This absorbs some of the blue light and, in turn, emits yellow light. Both are what are known as complementary colors of light. Therefore, when you mix them you obtain white light. The more fluorescence, the better. The fluorescence of this lunar mineral is so powerful that it would be a wonderful complement to LED bulbs. White light would be obtained in a much more efficient way, resulting in even greater energy savings. More achievements for China. The Asian country has become an expert in lunar geology, thanks to the Chang’e missions. In fact, the Changesite-(Y) phosphate was already discovered on Chang’e-5, directly related to this other mineral that a meteorite brought to Earth. For now, we can only dream. Logically, going to the Moon to excavate minerals is not very viable. And if it were, it would be good to think twice before jumping in headfirst. We also don’t know if there would be enough on the Moon. It would be necessary to explore it further to know. Therefore, the applications of lunar minerals in terrestrial technology are nothing more than hypotheses. It is interesting, but it does not have a close application in time. What these minerals do teach us. Analysis of lunar geology It can teach us many things. If we find mostly minerals that also exist here on Earth, we can understand that, at some point, similar conditions existed on Earth and the Moon. On the other hand, if many unknown minerals are found on Earth, as is already happening, it is understood that there were conditions on our satellite that have not occurred on our planet. All this serves to understand very well where we are and where we come from. Let’s stay with that instead of thinking about mining our satellite and leaving it without resources as we are already beginning to do on Earth.

We have genetically edited a spider to produce a fluorescent red cloth. And the implications are promising

Mutant spiders. It could be the premise of a film that mixes science fiction and terror, or someone’s nightmare with Arachnophobia. However, the first mutant spiders created by the human being respond to something much more innocent. But maybe even more interesting. Mutant spiders. A group of researchers He has genetically edited A group of spiders. The most curious of the results obtained by this team is probably a group of spiders that, after the edition, are capable of weaving a red spider web fluorescent spider. It is about First experiment of genetic edition in spiders of which we have knowledge. For this, the team resorted to specimens of the American domestic spider (PARASTIDA TEPIDARIORUM), A species that, like many others, uses its spider web not only for hunting but also to protect its eggs. A fascinating material. Spider silk is one of the most interesting materials in the animal world. Spiders are capable of segregating different types of fabric and among them, structural silks are among the most remarkable for their very tangled resistance that binds to its elasticity, lightness and the fact that it is a biodegradable material, explains the team responsible for the study. CRISPR-CAS9. In its experiment, the team turned to the “scissors” of genetic edition CRISPR-CAS9. They began the process focusing on a gene linked to the development of the eyes with the aim of obtaining a first easy result to identify. The team injected his tool of genetic edition in a female in order to eliminate the gene chosen in their reproductive cells and thus be able to detect changes in their litter. The Resutlanted: Spiders who did not develop their eyes. From the eyes to the silk. The first success led to repeat the test, but this time focusing on the genes responsible for coding some of the proteins present in the structural silk of the spiders. In doing so, spiders wove spider silk filaments of fluorescent red spider. The details of the experiment were published In an article In the magazine ANGEWANDTE CHEMIE. A first step. To be able to edit the genes responsible for the production of a material as interesting as the structural filaments of spider fabrics opens new doors when it comes to knowing this material and its biochemical origins. Of course, we can also pave the way for being able to synthesize it efficiently or even in the development of materials with similar properties. “We have demonstrated, for the first time in the world, that (the tool) CRISPR-CAS9 can be used” to incorporate a desired sequence in spider silk proteins, thus allowing the functionalization of these silk fibers, ” stood out in a press release Thomas Scheibel, co -author of the study. “The ability to apply CRISPR genetic edition to spider silk is very promising for material science; for example, it can be used to increase the already high spider silk breakage.” In Xataka | ‘The Last of Us’ is already happening in the animal world and the last species in suffering are the “spiders of the caverns” Image | Patrick Edwin Moran / University of Bayreuth

Malaysia came up with the idea of ​​painting its roads fluorescent to illuminate them at night. The problem was the price

In February 2024 we saw that the continuous line of a good part of the A-355, one of the roads with more accidents of Spanish territory, dawned with a thick continuous red line. It was a pilot measure by the DGT to highlight the prohibition of overtaking on that road. A few weeks earlier, a similar program was developed in Malaysia: repainting the road markings of certain roads with a photoluminescent paint. Not even a year has passed and it seems that they will not continue painting. The reason? It is too expensive, which has raised the question of… and they hadn’t thought of that before? The pilot. In mid-November 2023, the Government of Malaysia advertisement the launch of a pilot program that aimed to highlight the lines of certain roads. Using photoluminescent paint with the ability to glow at night. The authorities commented that these initiatives were suitable for dark areas that lacked public lighting. The lines shine for 10 hours and, in case of heavy rain, they also give off a certain shine that helps make them more visible, allowing drivers to stay in their lane. The images leave no room for doubt: it looks much better than the traditional white line, also better than reflective indicators. The project attracted attention. Initially, only 245 meters of road were painted at one intersection, representing about 490 meters of road markings, but other states began to carry out their own tests. Almost 20 times more expensive. The problems came practically from the beginning. The Malaysian Ministry of Works already warned that they were going to be very attentive to the results of the pilot program and the ability to paint on other roads, since the price of the new paint could be a problem. And so much so that it has ended up being an inconvenience. From the Ministry of Works reported that conventional paint costs about 40 ringgit per square meter, about 8.65 euros. Photoluminescent paint costs 749 ringgit per square meter, more than 160 euros. It costs 19 times more per square meter. Putting on the brake. Despite the enthusiasm with which the population received the measure, Malaysia’s deputy labor minister, Ahmad Maslan, commented a few weeks ago that it was not likely that they would continue painting. “The cost is too high, so we probably won’t continue with glow-in-the-dark lanes,” stated. It is curious when, months before, 31 roads had been identified that could have received this type of paint. Maslan stated that the tests did not meet the expectations of the ministry’s experts, without giving further explanations. Questions and suspicions. This is part of the eternal debate about priorities, budget and security, since we must remember that the areas that were going to receive this type of paintings are wooded and lack lighting, making it dangerous to travel through them due to interactions between humans. as by the action of animals crossing each other. And, evidently, the news has raised suspicions of corruption in local mediawith users who wondered if they didn’t know all this before starting the pilot project, what are those expectations that the painting has failed to meet… and that someone will have filled their pockets with the initial contract.
