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 ... >>

Tablets are more attractive than personal computers 14.11.2012

Tablet computers are becoming more and more popular, which leads the analytical agency Gartner to predict crazy growth in sales of these devices until 2016. Whether it is right to make plans for such a long term is not yet clear, but today it is impossible to deny obvious things - buyers pay special attention to tablet computers. The latest report from PriceGrabber showed that the majority of consumers prefer to receive a tablet as a gift for the coming holidays, overtaking PCs for the first time.

In figures, this situation is as follows: 59% of respondents admitted that they would like to receive a tablet as a holiday gift.

Otherwise, there are no big surprises. Apple products remain the most popular. 63% of respondents prefer iPad 3 or iPad 4 tablet computers, while 24% would like to get a brand new iPad mini. Twenty-two percent of the respondents were in favor of the Samsung Galaxy Note Tab tablet computers, and another twenty - in favor of the Amazon Kindle Fire HD model. The new Microsoft Surface devices are still behind the main competitors - only 13% of the "votes".

One of the reasons for the growing popularity of tablet computers is not so much the release of many interesting models, but the appearance on sale of inexpensive gadgets in the price range from $200 to $300.

If we consider only budget models of tablet computers, then Apple iPad mini is the leader here - 45% of buyers would like to purchase this particular device. Its main advantages are called: compactness, portability and low cost. In second place is the Amazon Kindle Fire HD with 27% of the "votes", and in third place are two options at once: Google Nexus 7 and Amazon Kindle Fire.
