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 ... >>

Bridge printed on a 3D printer 24.10.2017

In the city of Gemert, located in the south-east of Holland, the world's first concrete bridge built using 800D printing technologies has been opened. The structures of this bridge, which took three months to build, consist of XNUMX layers of concrete. At the same time, not ordinary concrete was used in the construction, but a special high-strength concrete designed specifically for a XNUMXD construction printer.

"The new bridge is quite small. But it was built using a XNUMXD printer, which makes it unique and the only one in the world today" - says Theo Salet (Theo Salet), representative of the Eindhoven University of Technology (Eindhoven University of Technology), - " One of the benefits of building XNUMXD printing technology is that the XNUMXD printer places concrete only where it is needed, resulting in less building materials than the traditional method, where ordinary concrete is poured into pre-prepared wooden forms (forms)."

Before putting the structure into operation, the bridge with 8-meter spans was checked for safety by specialists from the construction company BAM Infra. Despite the fact that the bridge is designed exclusively for cyclists, its design is able to support the weight of a truck loaded with two tons of cargo.

“Now we are looking at the future of building technology,” says Marinus Schimmel, CEO of BAM Infra, “We have been looking for new methods and approaches for a long time that will allow us to build urban infrastructure at a lower cost and with greater speed. In this case, we have strong evidence that XNUMXD printing requires less building materials, fewer human resources, and generates virtually no waste."
