witch Russia wonders how the West may to switch to green energy if it needs black coal By english.pravda.ru Published On :: Fri, 22 Oct 2021 21:20:00 +0300 The upcoming UN conference on climate change in Glasgow was supposed to show the world the triumph of the United States and the European Union as trendsetters for everything "green". Unfortunately for them, Europe faced an unprecedented energy crisis, which called into question not only the competence of officials from Brussels, but also the feasibility of the strategy to switch to green energy as soon as possible. Russia, which did not want to dive into the whirlpool of decarbonization, found itself in a more advantageous position. Nevertheless, Moscow has something to show in Glasgow on the climate agenda. China, the United States and India altogether account for more CO2 emissions than all other countries combined. Russia accounts for less than five percent, but the anger of Western politicians and journalists, who propagate environmental slogans, is directed primarily at Russia. Such a biased attitude towards Russia is based on the laws of hybrid war: dirty propaganda should keep citizens in good shape, while raising the degree of hatred. EU demonises Russia and wants more Russian gas When European politicians accuse Russia of the gas crisis, their accusations fit into the anti-Russian agenda just as perfectly. Gazprom strictly fulfills all of its contracts, but this argumentation falls on deaf ears in the EU. For example, EU chief diplomat Josep Borrell saw "deep geopolitical roots" in the rise in energy prices. The head of the European Commission, Ursula von der Leyen, reproached the Russian gas monopoly for "not responding to higher demand" in Europe. Her compatriot from the Green party, claiming the portfolio of the Minister of Foreign Affairs of the Federal Republic of Germany, Annalena Baerbock, stated that Russia was "playing poker" in matters of gas supplies. She has an ironclad argument: after all, European gas storage facilities are comparatively empty. Full Article Science

witch USA gradually switches Ukraine to terrorist war against Russia By english.pravda.ru Published On :: Fri, 26 Apr 2024 20:24:00 +0300 US Congress will provide $61 billion in military aid to Ukraine. Will Joseph Biden decide to transfer long-range missiles to Kyiv? Does Washington prepare for a terrorist war against Russia? Pravda.Ru asked these and other questions to Alexander Dudchak, candidate of economic sciences, leading researcher at the Institute of CIS Countries. The US Congress approved $61 billion in aid to Ukraine, but this money will be distributed between Ukraine, the American military-industrial complex and allies in Europe for arms procurement. What do you think of the bill? The decision did not come as a surprise. Of course, the bulk of the amount will be spent to support the US defence industry. The Americans say that they need long-term contracts to support the defence industry, and Washington is getting them by supporting Kyiv and the hostilities in Ukraine. A lion's share of those billions will be spent to support the US defence industry in the first place. In addition, they will allocate money for the National Nuclear Safety Committee and the Ministry of Health. Full Article Incidents
witch Structural analysis of a ligand-triggered intermolecular disulfide switch in a major latex protein from opium poppy By journals.iucr.org Published On :: 2024-08-29 Several proteins from plant pathogenesis-related family 10 (PR10) are highly abundant in the latex of opium poppy and have recently been shown to play diverse and important roles in the biosynthesis of benzylisoquinoline alkaloids (BIAs). The recent determination of the first crystal structures of PR10-10 showed how large conformational changes in a surface loop and adjacent β-strand are coupled to the binding of BIA compounds to the central hydrophobic binding pocket. A more detailed analysis of these conformational changes is now reported to further clarify how ligand binding is coupled to the formation and cleavage of an intermolecular disulfide bond that is only sterically allowed when the BIA binding pocket is empty. To decouple ligand binding from disulfide-bond formation, each of the two highly conserved cysteine residues (Cys59 and Cys155) in PR10-10 was replaced with serine using site-directed mutagenesis. Crystal structures of the Cys59Ser mutant were determined in the presence of papaverine and in the absence of exogenous BIA compounds. A crystal structure of the Cys155Ser mutant was also determined in the absence of exogenous BIA compounds. All three of these crystal structures reveal conformations similar to that of wild-type PR10-10 with bound BIA compounds. In the absence of exogenous BIA compounds, the Cys59Ser and Cys155Ser mutants appear to bind an unidentified ligand or mixture of ligands that was presumably introduced during expression of the proteins in Escherichia coli. The analysis of conformational changes triggered by the binding of BIA compounds suggests a molecular mechanism coupling ligand binding to the disruption of an intermolecular disulfide bond. This mechanism may be involved in the regulation of biosynthetic reactions in plants and possibly other organisms. Full Article text

witch Tax Code Switch By www.npr.org Published On :: Wed, 19 Apr 2023 20:26:59 +0000 This past January, researchers uncovered that Black taxpayers are three to five times as likely to be audited as everyone else. One likely reason for this is that the IRS disproportionately audits lower-income earners who claim a tax benefit called the earned income tax credit. And this, says law professor Dorothy Brown, is just one example of the many ways that race is woven through our tax system, its history, and its enforcement.Dorothy discovered the hidden relationship between race and the tax system sort of by accident, when she was helping her parents with their tax return. The amount they paid seemed too high. Eventually, her curiosity about that observation spawned a whole area of study.This episode is a collaboration with NPR's Code Switch podcast. Host Gene Demby spoke to Dorothy Brown about how race and taxes play out in marriage, housing, and student debt.This episode was produced by James Sneed, with help from Olivia Chilkoti.
