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 ... >>

While playing, the brains of parents and babies are synchronized 14.01.2020

During the game of babies aged 9-15 months and their parents, brain activity is synchronized. This happens in the prefrontal cortex. This is not observed between children and adults who simply sit side by side and read a book aloud, and synchronization itself seems to be at the heart of learning through communication.

The ability to communicate is formed in a person even in infancy: at a very early age, a child, for example, learns what will happen when he starts crying or screaming, and then he can use this as a way to get attention from a parent. Of course, this process is accompanied by the formation of strong neural connections, but this process itself has been studied only superficially.

Scientists led by Elise Piazza from Princeton University decided to test one key aspect of the formation of neural connections - the synchronization of brain activity during communication. Previously, researchers have shown that adult brain activity is synchronized during conversation, and in the new work, scientists decided to test whether the same thing happens during play - the main way of communication between infants and their parents.

The study involved 18 children aged 9-15 months and their parents. The brain activity of the participants was assessed using functional spectroscopy in the near infrared region (fNIKS) - this method allows you to visualize brain activity by blood flowing to active areas, since hemoglobin in it absorbs infrared radiation well.

During the experiment, the children played toys with their parents, listened to how they read books and talk. The brain activity of the infants was compared with the activity of the brain of its parent, and in the control condition - with the experimenter, who, being next to the child, but not looking at him, read a book to another person.

It turned out that during the game between the activity of the brain of a child and a parent, there is more synchronization than between the brain of a child and an adult when he just reads a book to him and does not look at him. Activity correlated most in the prefrontal cortex, but also in the parietal zone. In addition, synchronization was higher if the child and adult were looking at the same object.
