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 ... >>

Gym on board 16.06.2023

Australian airline Qantas is planning to install gyms on its aircraft to meet the needs of passengers and help them better cope with long flights exceeding 20 hours. New aircraft equipped with a special "health zone" in the form of a mini-gym will be available from 2025.

Gyms will appear on board the Airbus A350 aircraft, which will be operated by Qantas at the end of 2025. At first, these sports areas will be available on the longest routes, such as flights from Sydney to New York and London.

However, the installation of gyms will require a reduction in the number of seats in the cabin. Qantas chief executive Alan Joyce explains that the new A350s will have 100 fewer seats than the competition, but will provide more space for all classes of passengers as well as a "health zone" where they can warm up and exercise.

Prior to the implementation of the project, the airline conducted a survey among passengers to find out their needs. It turned out that being able to move and exercise on long flights was a very popular requirement.

The health zone will be located between the classrooms on the plane and will contain a buffet with healthy products. In the exercise area, screens will be installed on which coaches show movements that help improve the well-being of passengers.

The problem with long flights lasting more than 20 hours is that economy passengers require a long time to recover from such long periods in flight.
