Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Neurolink - mini brain implant 19.07.2019

Even before Elon Musk became popular thanks to successes in the development of return space rockets, electric vehicles and boring companies, his reputation directly indicated that he was a man of a special mind - and today Elon Musk has officially announced that he intends to take on some other developments in the near future. In particular, today he, together with his closest team, told the public about his new unique Neurolink project, which is a conceptually new type of brain mini-implant, whose main function is to allow its wearer to remotely control certain devices.

And this idea is really unusual and long-awaited, since many futurists and technology lovers have long dreamed of such a thing - however, Elon Musk noted that so far the development is theoretical. However, despite this, the project already demonstrates some very interesting ideas - in particular, the Neurolink chip is based on the use of a very thin - thinner than a human hair - system of neuronodes and wires that are directly connected to individual parts of the brain and brought out through a 2 mm hole in skull.

It sounds rather uncomfortable, but given the use of the latest laser technology, it becomes clear that the Neurolink project has a right to exist. Especially given the fact that the first clinical testing of the N1 chip - and this is the name of the first prototype of the brain chip - will begin as early as 2020. So it is quite possible that Elon Musk's project will become the first unique project in the presented segment.

It remains to wait for confirmation of this information, as well as the one that relates directly to the preliminary plans of the Musk team on the Neurolink project - because it is quite possible that with the onset of 2020 the company's priorities will change and we will see not quite what we expect now. On the other hand, it can be expected that the project will be constantly developed and supplemented, thus becoming closer and closer to the technological future that we all look forward to.
