  • Studies into the role of different frontal cortex areas in cognitive control have suggested that there is a rostral-to-caudal processing gradient. Drawing on anatomical and functional data from humans and monkeys, Badre and D'Esposito discuss whether this gradient might reflect a hierarchical organization.

  • Metasurfaces and metamaterials (or meta-optics) and their optoelectronic hybrid integration are set to drive the next era of computing, sensing and communications. As electronic systems reach fundamental limits, optical-enabled artificial intelligence emerges as a way forward, with meta-optics enabling speed, efficiency and scalability. We argue the need for comprehensive national innovation strategies to exploit the value of meta-optics in the photonics industry.

  • Filtering or gating relevant information into working memory has been attributed to the striatum. Here, the authors reveal neocortical filtering mechanisms, namely, rapid changes in oscillatory theta networks, that predict fast and flexible human behavior.

  • People can choose the correct actions to perform in a context-dependent way. Here, the authors show that this ability requires reaching a target brain state just prior to the response that encodes all task-relevant features in an integrated, high-dimensional, and temporally stable neural subspace.

  • The frontal lobes are critical for cognitive control over both abstract actions and motor plans. On the basis of the behavioral deficits of lesions patients, the authors report that there is a hierarchical organization of cognitive control, with rostral areas being required for decisions about more abstract actions and caudal areas being required for decisions about more concrete actions.

  • Humans have a capacity for hierarchical cognitive control—the ability to simultaneously control immediate actions while holding more abstract goals in mind. The authors show that neural oscillations establish dynamic communication networks within the frontal cortex and that these oscillations coordinate local neural activity with increasing cognitive control.

  • The human brain can efficiently retrieve information from long-term memory and use it to guide action but how the brain selects the most useful information in each case is unclear. Here the authors show that reinforcement learning mechanisms, based on expected value and prediction error fMRI signals in striatum, play a role in memory control processes guiding behavior.

  • Scientific collaborations among nations to address common problems and to build international partnerships as part of science diplomacy is a well-established notion. The international flow of people and ideas has played an important role in the advancement of the ‘Sciences’ and the current pandemic scenario has drawn attention towards the genuine need for a stronger role of science diplomacy, science advice and science communication. In dealing with the COVID-19 pandemic, visible interactions across science, policy, science communication to the public and diplomacy worldwide have promptly emerged. These interactions have benefited primarily the disciplines of knowledge that are directly informing the pandemic response, while other scientific fields have been relegated. The effects of the COVID-19 pandemic on scientists of all disciplines and from all world regions are discussed here, with a focus on early-career researchers (ECRs), as a vulnerable population in the research system. Young academies and ECR-driven organisations could suggest ECR-powered solutions and actions that could have the potential to mitigate these effects on ECRs working on disciplines not related to the pandemic response. In relation with governments and other scientific organisations, they can have an impact on strengthening and creating fairer scientific systems for ECRs at the national, regional, and global level.
