The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

paper that stores electricity 15.12.2015

In Sweden, created "paper" that stores the energy of electricity. Researchers working at Linköping University have developed a material with an outstanding ability to store electricity. Scientists themselves call it "energy paper".

The material consists of cellulose nanofibers and a conductive polymer. A sheet of such "paper" with a diameter of 15 cm and a thickness of less than 1 mm has a capacitance of 1 F. This is comparable to the capacitance of supercapacitors available on the market today. The sheet can withstand hundreds of recharge cycles and recharges in seconds. The new material demonstrates record values ​​for organic electronics in four parameters, including capacitance and current strength.

One of the most promising areas of application of a material capable of storing energy, scientists consider power supply systems using renewable sources - for example, wind generators or solar panels. The fact is that such systems are characterized by fluctuations in the amount of generated energy, and the presence of a capacity for its storage allows for uniform power supply to the load, regardless of weather conditions, time of day or year.

The advantages of the material, its creators include the ability to produce sheets of arbitrary thickness, as well as the fact that a sheet of "energy paper" can be folded like a sheet of ordinary paper.
