Is American food healthy?

A 2000 US government study found that only 12% of Americans eat healthy. About 52% of the country's inhabitants are overweight; this figure increased by 1991% compared to 20. Obesity affects 18% of adults, and the number of overweight children has increased markedly in ten years - from 5% to 15%.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 ... >>

Edible gelatin robot 15.03.2017

Researchers at the Swiss Federal Polytechnic School of Lausanne have published a scientific paper that talks about the creation of gelatin actuators - a technology that could eventually allow the creation of edible robots.

The research is still at an early stage, and the staff of the educational institution does not fully understand how this technology can be useful. In an interview with TechCrunch, Dario Floreano, director of the university's Intelligent Systems Lab, acknowledged that the team may not be operating in a very logical order. The work, presumably, was the result of a desire to create something new - using this mechanism, the researchers did not originally plan to solve some pressing problem.

"A year ago, alumnus and co-author Jun Shintake came to me and said, 'We make all these biological robots, but biological systems are edible and our systems are not,'" Floreano said. "I thought it was interesting. Food and robots have completely different limitations and properties, and before I even thought about what it could be, I thought that seeing if we could combine the two would be a very interesting challenge."

Floreano offered a list of potential uses for edible robots, including food that can move itself from colder to warmer places and vice versa, as well as independently reach a person or animal to feed it. This method could also be used for automated drug delivery.

A similar study last year by the Massachusetts Institute of Technology reported on the creation of an origami robot made from dried pig intestines that is placed in a person's stomach to remove swallowed items like batteries. However, the design of the Federal Polytechnic School of Lausanne differs in that its mechanisms are completely digestible and do not require extraction from the human body.

As for the taste qualities of such robots, the existing gelatin prototype has almost none. But the researchers decided to team up with the School of Hotel Management of Lausanne to create mechanisms that would be not only useful, but also tasty.
