Scientists at Altai State University have created a device that can use artificial intelligence to count the number of bacterial cells, microscopic fungi, and other microorganisms. This was announced by the rector of the university, Sergei Bocharov.
The device is based on the principle of fluorescence. Cells are stained with special substances that begin to glow when exposed to blue light. The device then automatically analyzes the image and begins counting.
This can be used in biotechnological processes to understand how microorganisms grow, as well as in food production to assess the degree of contamination of surfaces and equipment.
The device consists of a camera with a lens for shooting and a microcontroller for control, which are housed in a small case. To operate the device, it must be connected to a computer, smartphone with a specially installed program, or tablet via USB.
The new counter is characterized by high speed, accuracy, and compact size.
Earlier, www1.ru reported that a group of scientists, using the DeepZ neural network, made a discovery that overturned ideas about the genetic code. They found that Z-flips — unique sections of "mirror DNA" twisted to the left — play a key role in regulating gene activity. These sites help speed up the "reading" process of neighboring genes, after which cells adapt more quickly to changes.
