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 ... >>

Magnetic particles pollute the brain 23.09.2016

Particles of magnetite - a mineral with magnetic properties - are often found in living organisms, and in this connection they usually speak of a magnetic feeling: allegedly, magnetite, moving under the action of a geomagnetic field, irritates receptor cells, and thus animals learn where the north is, where is the south, and where in general they are. The human body also has magnetite: particles of it were found in the brain about a quarter of a century ago, and recently Joe Kirschvink, the geophysicist at the California Institute of Technology who discovered "human magnetite", reported that our brain can also sense a magnetic field.

However, magnetite has a significant disadvantage - it stimulates the appearance of aggressive oxidizing molecules that damage cellular proteins, lipids and DNA. On the other hand, it is known that an increased content of magnetite particles occurs in the brain of patients with Alzheimer's syndrome, and that magnetite somehow enhances the toxicity of pathogenic protein complexes formed in nerve cells in this disease. And at the same time, it is believed that all of our magnetite is biogenic, that is, created by the body itself through some kind of biochemical reactions. And then the question arises whether magnetite particles are really needed for geomagnetic feeling - maybe they accumulate only because some pathological processes begin in the brain, and the nervous system cannot cope with the collection of dangerous debris.

However, everything is actually simpler: in an article in PNAS, researchers from Lancaster University write that our magnetite may be ordinary industrial pollution that has entered the brain from the external environment. Barbara Maher and her colleagues from Oxford, the universities of Glasgow, Manchester, the University of Montana and the National Autonomous University of Mexico City analyzed post-mortem brain samples taken from dozens of people living in Mexico City and Manchester. There was magnetite in the samples, but for the most part it didn't look biological at all.

If a magnetite particle is formed in a cell, then its shape is a tetrahedron or an octahedron, but those found in the brains looked rounded, spherical. Such nanospheres are obtained with strong heating - for example, when fuel is burned in car engines or simply on an open fire. Biogenic tetrahedra and octahedra also existed, but for one biogenic particle there were at least a hundred abiogenic particles that entered the brain from the external environment. Along the way, particles of platinum, nickel and cobalt were found in the nervous tissue, which could not enter the human body from anywhere, except from the outside.

The size of all "external" particles is about 150 nanometers, so they are quite capable of entering the brain through the nose and olfactory nerve pathways. It is known that in the air of large cities, and especially along roads, many magnetite particles fly, so that local residents can easily breathe in "magnetic nanodust". Whether this gives special sensitivity to the magnetic field is not known; but in general, taking into account what has been said above about the connection between magnetite and Alzheimer's disease, the more pressing question here is how to remove or neutralize particles that have entered the brain so that they do not have time to harm nerve cells.
