SARS-CoV-2 genomic epidemiology shows increased breakthrough but not re-infection rates, by the Beta, Gamma, or Delta variants compared to Alpha.
A photochemical mechanism was experimentally discovered and denoted proton-coupled energy transfer (PCEnT). A series of anthracene-phenol-pyridine triads formed the local excited anthracene state after light excitation at ca. 400 nm, which led to ...
At her lowest moment, this industry scientist found strength in weakness
When Vanderbilt University physician and neuroscientist Matthew Schrag first grew suspicious of work underlying a major theory of Alzheimer’s disease (see main story, p. 358), he was following a different trail. In August 2021, he provided analysis for a petition to the Food and Drug Administration (FDA), requesting that it pause two phase 3 clinical trials of Cassava Sciences’s Alzheimer’s drug Simufilam. The petition claimed some science behind the drug might be fraudulent, and the more than 1800... Читать дальше...

China is home to 10% of the world’s wetland areas, but many of those wetlands are threatened by development (1). To increase conservation efforts, China’s first wetland protection law, which came into force on 1 June (2), will charge a fee to developers whose projects result in wetland area losses. The fees will pay for restoring wetlands with comparable qualities and quantities elsewhere. When this strategy has been implemented in the past, transparency has been insufficient. The wetlands law, as well as other laws requiring restoration fees... Читать дальше...
As global conservation and restoration policies focus on a land and sea framework, freshwater biodiversity and services continue to decline at alarming rates (1). If freshwater ecosystems are overlooked, their sustainability could be compromised when decision-makers evaluate trade-offs with land and sea conservation and development goals. To protect freshwater biodiversity and vital services, international agreements must explicitly acknowledge freshwater ecosystems as a unique realm and set specific goals to address their problems (2, 3).

УрБК, Екатеринбург, 21.07.2022. Средний размер выданных в Свердловской области автокредитов в июне составил 1 млн 174 тыс. 850 руб. Это на 2,1% больше уровня предыдущего месяца (1 млн 150 тыс. 646 руб.), говорится в исследовании Национального бюро кредитных историй (НБКИ). В целом по стране показатель за месяц вырос на 1,1% — с 1,22 млн руб. до 1,24 млн руб. Напомним, что в январе текущего года показатель составлял 1,29 млн руб., в феврале — 1,35 млн руб., в марте — 1,27 млн руб., в апреле — 1,21 млн руб. Читать дальше...
