We have twice two also four, but somehow it comes out more briskly

Turgenev I.S.

Phraseologism: We have twice two also four, but somehow it comes out more briskly.

Meaning: About selfish patriotism.

Origin: From the novel "Smoke" (ch. 14) by I. S. Turgenev (1818-1883). Potugin's words, which for a long time became an analogue of leavened patriotism.

Random phraseology:

Shine - and no nails!

Meaning:

About optimism, love of life, purposefulness.

Origin:

From the poem "An extraordinary adventure that happened with Vladimir Mayakovsky in the summer at the dacha" (1920) by Vladimir Vladimirovich Mayakovsky (1893-1930): "Shine - and no nails! That's my slogan - and the sun!"

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Synthetic nerves work in the light 09.04.2016

Researchers from Oxford have created an artificial analogue of the neural circuit: synthetic cells, packed using a 3D printer in a kind of conductive tissue, were able to conduct an electrical impulse.

Cells, tiny drops of water with a volume of 50-100 picoliters, enclosed in a single-layer lipid membrane. Such drops contained not only water, they also contained DNA with genes encoding transmembrane proteins, and all the necessary apparatus for protein synthesis. Transmembrane proteins synthesized in the "cell" formed a through channel in the membrane - this is how an "intercellular contact" appeared between two drops, through which an electrical signal could slip through. The work of the "nerve chain" depended on lighting - the "cells" also contained a special photosensitive protein, which, under the influence of light, bound to DNA and activated the genes of transmembrane proteins recorded in it.

A dense ordered stacking of droplets was achieved, as mentioned above, using a 3D printer. The very technology of XNUMXD printing from such "cells" has been developed for a long time, but now the authors of the work had to develop a new recipe for them, so that both the "cells" themselves and the molecular machines contained in them for transcription (synthesis of RNA copies to DNA) and translation ( protein synthesis to RNA) after passing through the printer would remain in working condition.

Michael J. Booth and his colleagues believe that the main achievements of Michael Booth and his colleagues are that they managed to build a light switch into the nervous chain, and that the propagation of the impulse was not limited to two "cells", that the signal went further - to the third drop, fourth, tenth and etc. In such an artificial system, it is quite possible to study some patterns of impulse propagation through conductive tissues, but in the future, researchers want to combine artificial cells with real ones.

To do this, two technological problems need to be solved: first, the 3D-printed droplet complexes "live" in an oily environment, while real cells need an aqueous solution; secondly, pore proteins in artificial cells are embedded in a single-layer lipid membrane, while in real cells it is two-layered, and it is not known whether a transmembrane protein pore will form between them. Perhaps the contact between an artificial and a real cell can be organized in the form of a synapse, when a certain space remains between the cell membranes, and the impulse is transmitted using special chemical neurotransmitter molecules.
