TL;DR: Gibberellic acid enhances the synthesis of alpha-amylase in isolated aleurone layers of barley-seeds and enhances the formation of ribonuclease which increases linearly over a 48 hour period.
Abstract: Gibberellic acid enhances the synthesis of α-amylase in isolated aleurone layers of barley-seeds (Hordeum vulgare var. Himalaya). In the presence of 20 mm calcium chloride the amount of enzyme obtained from isolated aleurone layers is quantitatively comparable to that of the half-seeds used in earlier studies. After a lag period of 6 to 8 hours enzyme is produced at a linear rate. Gibberellic acid does not merely trigger α-amylase synthesis, but it is continuously required during the period of enzyme formation. Enzyme synthesis is inhibited by inhibitors of protein and RNA synthesis. Small amounts of actinomycin D differentially inhibit enzyme release and enzyme synthesis suggesting 2 distinct processes. Gibberellic acid similarly enhances the formation of ribonuclease which increases linearly over a 48 hour period. During the first 24 hours the enzyme is retained by the aleurone cells and this is followed by a rapid release of ribonuclease during the next 24 hour period. The capacity to release the enzyme is generated between 20 and 28 hours after the addition of the hormone. Ribonuclease formation is inhibited by inhibitors of protein and RNA synthesis. These inhibitors also prevent the formation of the release mechanism if added at the appropriate moment.

TL;DR: The surface uplift of mountain belts is generally assumed to reflect progressive shortening and crustal thickening, leading to their gradual rise as mentioned in this paper, but recent studies of the Andes indicate that their elevation remained relatively stable for long periods (tens of millions of years), separated by rapid (1 to 4 million years) changes of 1.5 kilometers or more.
Abstract: The surface uplift of mountain belts is generally assumed to reflect progressive shortening and crustal thickening, leading to their gradual rise. Recent studies of the Andes indicate that their elevation remained relatively stable for long periods (tens of millions of years), separated by rapid (1 to 4 million years) changes of 1.5 kilometers or more. Periodic punctuated surface uplift of mountain belts probably reflects the rapid removal of unstable, dense lower lithosphere after long-term thickening of the crust and lithospheric mantle.

TL;DR: A US national experiment showed that a short, online, self-administered growth mindset intervention can increase adolescents’ grades and advanced course-taking, and identified the types of school that were poised to benefit the most.
Abstract: A global priority for the behavioural sciences is to develop cost-effective, scalable interventions that could improve the academic outcomes of adolescents at a population level, but no such interventions have so far been evaluated in a population-generalizable sample. Here we show that a short (less than one hour), online growth mindset intervention-which teaches that intellectual abilities can be developed-improved grades among lower-achieving students and increased overall enrolment to advanced mathematics courses in a nationally representative sample of students in secondary education in the United States. Notably, the study identified school contexts that sustained the effects of the growth mindset intervention: the intervention changed grades when peer norms aligned with the messages of the intervention. Confidence in the conclusions of this study comes from independent data collection and processing, pre-registration of analyses, and corroboration of results by a blinded Bayesian analysis.

TL;DR: This article used a national survey of Americans conducted shortly after the September 11, 2001 attack on America to investigate people's willingness to trade off civil liberties for greater personal safety and security, finding that the greater people's sense of threat, the lower their support for civil liberties.
Abstract: In the tradition of research on political tolerance and democratic rights in context, this study uses a national survey of Americans conducted shortly after the September 11, 2001 attack on America to investigate people’s willingness to trade off civil liberties for greater personal safety and security. We find that the greater people’s sense of threat, the lower their support for civil liberties. This effect interacts, however, with trust in government. The lower people’s trust in government, the less willing they are to trade off civil liberties for security, regardless of their level of threat. African Americans are much less willing to trade civil liberties for security than whites or Latinos, even with other factors taken into account. This may reflect their long-standing commitment to the struggle for rights. Liberals are less willing to trade off civil liberties than moderates or conservatives, but liberals converge toward the position taken by conservatives when their sense of the threat of terrorism is high. While not a forecast of the future, the results indicate that Americans’ commitment to democratic values is highly contingent on other concerns and that the context of a large-scale threat to national or personal security can induce a substantial willingness to give up rights.
