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 ... >>

TOSA electric bus system 30.06.2014

The Swiss company ABB Secheron, together with partners, plans to deploy in Geneva in 2017 a network of electric buses TOSA (Trolleybus Optimization Systeme Alimentation) with a unique fast battery charging system.

It is assumed that special charging stations will be placed at some stops along the route of the vehicle. Having approached such an installation, the bus will be able to connect to an energy source using a special robotic arm located on the roof. The laser sensor will be responsible for ensuring the accuracy of the connection.

The charging station will provide a power of 400 kW. It is assumed that the process will take about 15 seconds, and the energy received is guaranteed to be enough to get to the next charging point.

TOSA buses are designed to carry up to 133 passengers. Since recharging will be carried out on the way, massive battery packs can be dispensed with. By the way, in the case of TOSA, the batteries are located on the roof.

Researchers from the Federal Polytechnic School of Lausanne have already developed a special computer model that will help make the TOSA system as cost-effective as possible. Nearly 60 parameters are taken into account when evaluating the efficiency, in particular, the salary of drivers, the distance between stops, the number of charging stations, the durability of batteries, the timetable, etc.

TOSA buses are currently being tested on the route between Geneva airport and the Palexpo exhibition centre.
