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 ... >>

Electric bike with a record range 24.09.2017

The Ukrainian company DelFast has developed an electric bicycle that has the world's largest power reserve - 380 kilometers. More than some electric cars!

DelFast is engaged in courier delivery of goods exclusively on electric bikes - so as not to pollute the environment. Now, it looks like their footprint will be greatly expanded thanks to the electric bike, which boasts an incredible range of 380 kilometers. This is several times more than any competitor and even a little more than the basic version of the Tesla Model 3 electric car, which overcomes only 354 km.

The cruising speed of the Ukrainian electric bike is 45 km/h, the maximum is 55 km/h. The frame-mounted battery is made in the USA and is rated for XNUMX charge cycles. It supports energy recovery, and with the help of two USB connectors, you can charge gadgets from it on the road - for example, a smartphone and tablet. The electric bike has a headlight, a lamp with a brake light and direction indicators.

Also, the electric bike is equipped with an anti-theft system, a GPS tracker, a start / stop button and the ability to remotely start the motor.

The expected cost of the bike is 3000 USD.
