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.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
