A fundamentally new approach to computer identification of words was been suggested by Russian scientists. With its help, people will be able to give orders even to the most primitive cellular phones.
A sentient being recognizes without difficulty a familiar word regardless of the voice and intonation it is pronounced with. “Six” or “eight” remain six and eight for a person no matter how they are pronounced – in a loud voice or in a whisper, in an excited or a calm voice, by the voice of an old man or a child, by that of a man or a woman. The brain of a person immediately separates the semantic part from the mass of background sounds.
As for a machine, each variant of voice is unique. That is why the speech recognition program usually has to be taught. As a result of training, an enormous library appears in the memory of the silicon brain, where thousands of possible options of pronunciation of the same words (for example, numerals) are stored. Having heard a word, the computer would look through the library and almost certainly something similar to the heard word will be found in it.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
