This year, spring is so late that the global climate warming is hardly believable. Is it applicable to Russia? Probably the fact is that weather cataclysms and anomalies are now occuring more and more frequently, and warm autumn gets balanced by frosts and cold spring? Phenologists from the Institute of Global Climate and Ecology of Rosgidromet (Hydrometeorological Committee), Russian Academy of Sciences, decided to find out what was happening in reality in European part of Russia, and analyzed observational data for the last 30 years.
Phenology – is the ancient science about seasonal natural phenomena, times of their occurrence and reasons for these processes. In contrast to meteorologists, phenologists do not measure temperature or precipitations, instead they keep records from year to year about such facts as when plants’ buds swell, when leaves, blossom and fruit appear, when animals awaken from hibernation, about seasonal migrations, adult insects going out of chrysalices, etc. As was explained by Alexander Minin, chief research assistant, Doctor of Science (Biology), Institute of Global Climate and Ecology of Rosgidromet, Russian Academy of Sciences, the climate in European part of Russia in general had become warmer indeed.
Judging by majority of attributes, plants’ vegetation period (when plants are growing up and developing) has become longer: defoliation begins later and later, and spring comes a bit earlier. Birch tree leaves come out earlier, and bird cherry tree and lime-tree break into bloom earlier. In the northern regions of European part, in the taiga area, these deviations are felt stronger, and the spring comes five days earlier on average than it did in pervious years, but closer to the south, in the moderate climate – it comes only one day earlier. In the south of European part of Russia, for example, near Tambov and Voronezh, there is no shift in dates at all, or, vice versa, spring comes a bit later than it was recorded earlier. As for summer, within the last 30 years, it is slightly cooler in European part of Russia.

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...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
