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 ... >>

Human tissues can be printed 01.12.2012

Scientists are one step closer to being able to print human tissue implants or even prosthetic body parts with an inkjet printer, thanks to the development of a special kind of ink.

Researchers have long known about the possibility of using existing inkjet printer heads to print living human cells on XNUMXD forms, the main difficulty was precisely the structure of the ink that could carry the cells through the printer. A research team was set up at the University of Wollongong in Australia to develop new bioinks that would promote cell viability while improving control over their positioning during the printing process.

“To date, none of the existing inks have both of these qualities at the same time,” says one of the researchers Cameron Ferris. “Our new bioinks are both printable and cell-friendly: they prevent cell sedimentation and allow for their controlled placement.”

"Creating a substance that provides a method for delivering living tissues not only brings us closer to the development of actually working medical devices for such purposes, but also provides ways for further experiments that will help to open up until now unknown areas of basic science," said Professor Gordon Wallace, director of the research center. "Such advances in biomanufacturing could lay the foundation for defeating diseases hitherto considered untreatable."
