Specialists of the Institute of Comprehensive Social Studies (Modern University for the Humanities) have carried out detailed analysis of changes in the matrimonial relations structure in the world since 1950 to 2000. The researchers considered four types of matrimonial relations: monogamy (one man – one woman) and three types of polygamy - polygyny (one man – several women), polyandry (one woman - several men) and polygyandry (several women – several men). The fifth type of reproductive relations - promiscuity, i.e. lack of permanent conjugal units between sexual partners - was not taken into account.
As for monogamy, it can be complete (men and women have only one partner during the entire life span) and serial when men and women enter new monogamous marriages after divorce. As compared to animals, monogamy is to a larger extent biologically tied up with human beings, this being explained by the necessity of joint upbringing of children for a long period. Nevertheless, only 30 percent of human communities are monogamous.
For analysis, the researchers used information from the International Database of US Census Bureau across 160 countries about which the most complete data was available since 1950 through 2000. The following trends were discovered.

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...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
