What Russian writer affectionately called his wife a crocodile?

Anton Pavlovich Chekhov, in correspondence with his wife Olga Leonardovna Knipper, used to her, in addition to standard compliments and affectionate words, very unusual ones: "actress", "dog", "snake" and - feel the lyricism of the moment - "the crocodile of my soul."

Authors: Jimmy Wales, Larry Sanger

What insects hunt with bioluminescence?

Found in New Zealand and Australia, fungal mosquitoes of the genus Arachnocampa in the larval phase have the property of bioluminescence. Attached to the ceiling of the caves, they develop and hang sticky threads down. They come across other insects that fly to the glow like moths to a lantern.

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 ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Graphene electric generator on fluctuations in ambient temperature 21.02.2018

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new electrical energy generator they call a "thermal resonator". It allows you to get electricity to power the sensors by changing the ambient temperature.
К
The generator design includes a foamed metal (copper or nickel) coated with graphene and immersed in a material whose phase state depends on temperature. A small prototype, made by scientists to test the concept, makes it possible to obtain a potential difference of 10 mV and a power of 350 mW at a drop of 1,3 ° C during the day.

The advantages of the generator include its independence from the instantaneous values ​​of illumination or wind strength, as is the case in the case of solar panels or wind generators. The generator allows you to use not only daily fluctuations, but also other cycles of temperature change, for example, associated with the operation of engines or mechanisms.

Such a generator can provide power to sensors and other electronic devices.
