What advice did Karl Marx give to future generations on his deathbed?

When Karl Marx lay ill in bed shortly before his death, a maid asked him if he would like to leave some wise advice for future generations. Marx replied: "Get out of here! Last words are for fools who said little in life."

What insects tend to compensate for love failures with alcohol?

American biologists, studying the mating behavior of male fruit flies, offered them a choice of two feeders - one contained ordinary sugar syrup, the other had the same, but diluted with alcohol. Those males whose courtship was rejected by the females drank from the trough with alcohol much more often. The reason for this was a reduced concentration in their body of a protein called neuropeptide F, which acts on the pleasure center of the insect - not receiving it due to lack of mating, the flies tried to fill the gap with alcohol consumption.

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 ... >>

transistor molecule 22.02.2022

Swedish scientists have succeeded in making a simple hydrocarbon molecule with the function of a logic gate, like those that power transistors. This discovery allows us to get closer to the creation of electrical components with a size of several nanometers.

"We have developed a simple hydrocarbon molecule that changes shape and at the same time turns from non-conductive to conductive, conductive under the influence of an electric potential. The secret of success was the creation of a so-called anti-aromatic ring in the molecule, so that it became more reliable and able to accept and transmit electrons," - said one of the researchers, Daniel Strand.

Many organic molecules are made up of six carbon aromatic benzene rings. However, these molecules do not change their properties or shapes when exposed to electricity. So scientists turned to rings of eight carbon atoms. If two electrons are introduced into such a molecule, it becomes flat and conductive, although before that it was barrel-shaped and non-conductive. In this sense, its properties are similar to those of a transistor.

The uniqueness of this molecule is in its simplicity. It consists only of carbon and hydrogen atoms, so it is not difficult to produce it artificially.

The discovery by Swedish chemists means that it is now possible to think about developing electrical switches and new mechanical systems at the scale of one molecule based on antiaromatic hydrocarbons that underlie even smaller and faster computers.

Molecules that change shape in response to an electrical potential open up fascinating possibilities. Energy-efficient computer architectures can be imagined, and in the future perhaps molecular-scale electrical machines.

By deforming graphene in a certain way - flat rings of carbon atoms - British scientists obtained a transistor last year. Their invention opens up new prospects for the miniaturization of electronics - a microchip with such transistors would be 100 times smaller than usual.
