Band 3 mediates the Cl and HCO exchange across the red blood cell membrane and plays a pivotal role for delivering oxygen appropriately to metabolically active tissues. For understanding molecular mechanisms, it is essential to know the structure and function relationship. In terrestrial environments, however, nobody could make good quality crystals of Band 3 for the X-ray crystallographic study. In this study, we purified the transmembrane domain of Band 3 from human red blood cells and crystallized the purified Band 3 without the Fab fragment at the International Space Station "KIBO" under microgravity environments.

Since 2006, simple outdoor gyms have been installed on public squares all over Brazil. From the beginning, they were mainly conceived as for use by older people - especially women - within an international movement of 'healthy cities'. Based on an ethnography in Rio de Janeiro, our aim is to show in particular the politico-commercial dimensions of the fitness equipment.

Resting state electroencephalography (EEG) has proved useful in studying electrophysiological changes in neurodegenerative diseases. In many neuropathologies, microstate analysis of the eyes-closed (EC) scalp EEG is a robust and highly reproducible technique for assessing topological changes with high temporal resolution. However, scalp EEG microstate maps tend to underestimate the non-occipital or non-alpha-band networks, which can also be used to detect neuropathological changes.

Individuals can strongly vary in their ability to process face identity. Understanding the mechanisms driving these differences is important for theoretical development, and in clinical and applied contexts. Here we investigate the role of face-space properties in relation to individual face identity processing skills.

The assessment of research performance is widely seen as a vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress. Academic institutions need to take critical decisions on hiring and promotion, while facing external pressure by also being subject to research assessment. Here we present an outlook on research assessment for career progression with specific focus on promotion to full professorship, based on 314 policies from 190 academic institutions and 218 policies from 58 government agencies, covering 32 countries in the Global North and 89 countries in the Global South.
