Population, Environmental Risks, and the Climate Crisis (PERCC) [PDF]
, 2020 In 2016, the Population Council began to develop evidence on how to strengthen the resilience of vulnerable populations to adapt to environmental risks and the effects of extreme climate change.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Spatiotemporal evolution and influencing factors of urban growth and shrinkage in Central and Southern Liaoning: Based on the perspective of physical urban area [PDF]
Ziyuan Kexue[Objective] Due to the limited development of spatialization technology for socioeconomic data, previous research on the factors that affect urban shrinkage at the physical area scale of cities has mostly remained at the stage of qualitative analysis or ...

Fennia: International Journal of Geography, 2022 Cities acknowledge the diversity of their population and consider the multicultural component a richness of their socio-cultural assets. Immigrants contribute to the reshaping of urban space in many European cities through their amenities.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
