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 ... >>

9th Gen Intel Core Mobile Processors 23.04.2019

Intel has officially unveiled the ninth generation of high-performance H-series mobile processors. They are available in Core i5, i7 and i9 versions and are designed for demanding tasks such as gaming or video editing.

The flagship of the new generation of processors is the Core i9-9980HK - the first mobile "octa-core" with a frequency of 5,0 GHz and an unlocked multiplier. He received 16 MB of L3 cache. There is a simpler modification - Core i9-9980H, its multiplier is locked, and the maximum frequency in Turbo Boost mode is limited to 4,8 GHz. All six mobile processors support up to 4GB of DDR2666-128 RAM, Intel Optane SSDs, and Wi-Fi 6 wireless standard for up to 2,4Gbps of bandwidth.

The manufacturer claims that compared to solutions three years ago, the new processors provide up to 56% performance gains in games, and up to 4% in 54K video editing. XNUMXth Gen Intel Core mobile processors are already available in laptops from Acer, Asus, Dell, HP, Razer, Lenovo and MSI.

Intel also expanded its ninth-generation desktop processor portfolio with new models in its Core i3, i5, i7, i9, Pentium Gold, and Celeron product lines. In the last two, they appeared for the first time, which should serve as an impetus for the creation of low-cost entry-level systems based on new processors. All new products still use the 14nm process technology.
