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 ...

Indexing the vulnerability of biotopes to landscape changes
Ecological Indicators, 2019 Abstract Biodiversity loss is one of the great challenges of our times, and it is primarily driven by losses of natural and semi-natural areas. To avoid further biodiversity losses, landscape planning and ecosystem management could benefit from a condensed measure that tracks regional and cumulative ecological degradation from past and ongoing ...

A Study on Application of Landscape Diagnosis Index and Landscape Formation Plan of Rural Villages
Journal of Korean Society of Rural Planning, 2013 In this study, it propose what the landscape elements is to be improved urgently and how to improve landscape by reflecting the rural village characteristics away from the spatial integrated landscape planning. The study area for landscape research is selected as the 9 rural villages in Chungcheongbuk-do, and research is done by using village unit ...

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 ...

The Landscape Resilience Index: a flexible tool for integrated landscape management
Frontiers in Sustainable Food SystemsGlobally, landscapes are subject to intensifying and interacting environmental pressures, making landscape resilience increasingly important for sustaining ecosystem services, livelihoods, and long-term development. Integrated landscape management offers a promising approach to strengthening resilience, yet many existing monitoring frameworks are not ...

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.
