Changing Demographics of Scientific Careers: The Rise of the Temporary Workforce
Contemporary science has been characterized by an exponential growth in publications and a rise of team science. At the same time, there has been an increase in the number of awarded PhD degrees, which has not been accompanied by a similar expansion in the number of academic positions.
Scientific Prize Network Predicts Who Pushes the Boundaries of Science
Scientific prizes confer credibility to persons, ideas, and disciplines, provide financial incentives, and promote community-building celebrations. The article examines the growth dynamics and interlocking relationships found in the worldwide scientific prize network.
Reproducibility failures occur even in fields such as mathematics or computer science that do not have statistical problems or issues with experimental design. Suggested policy changes ignore a core feature of the process of scientific inquiry that occurs after reproducibility failures: the integration of conflicting observations and ideas into a coherent theory.
Article suggesting that positive feedback in funding may be a key mechanism through which money is increasingly concentrated in the hands of a few extremely successful scholars, but also that the origins of emergent distinction in scientists' careers may be of an arbitrary nature.

Four concrete suggestions - for Childcare, Accommodate families, Resources, Establish social networks - are directed toward research societies and conference organizers who are willing to take a leadership role in creating solutions, either incrementally or on a large scale.
Science is said to be suffering a reproducibility crisis caused by many biases. How common are these problems, across the wide diversity of research fields? We probed for multiple bias-related patterns in a large random sample of meta-analyses taken from all disciplines.
A time traveler from 1915 arriving in 1965 would have been astonished by the scientific theories and engineering technologies invented during that half century. One can only speculate, but it seems likely that few of the major advances that emerged during those 50 years were even remotely foreseeable in 1915.
Evolution and convergence of the patterns of international scientific collaboration
This study shows that the long-run patterns of international scientific collaboration are generating a convergence between applied and basic fields. This convergence of collaboration patterns across research fields might be one of contributing factors that supports the evolution of scientific disciplines.
Defining and identifying Sleeping Beauties in science
Scientific papers typically have a finite lifetime. Previous studies pointed out the existence of a few blatant exceptions: papers whose relevance has not been recognized for decades, but then suddenly become highly influential and cited. This study investigates how common Sleeping Beauties are in science.
Reproducibility alone is insufficient to address the replication crisis because even a reproducible analysis can suffer from many problems that threaten the validity and useful interpretation of the results.
