Single cell technologies are rapidly generating large amounts of data that enables us to understand biological systems at single-cell resolution. However, joint analysis of datasets generated by independent labs remains challenging due to a lack of consi
Recombinant adeno-associated viruses (rAAVs) are efficient gene delivery vectors via intravenous delivery; however, natural serotypes display a finite set of tropisms. To expand their utility, we evolved AAV capsids to efficiently transduce specific cell types in adult mouse brains. Building upon our...
Predation pressure is one of the main influences onnatural selection, which means that it also has a huge influence on evolution. Prey must evolve defenses to fight or avoid potential predators in order to survive and reproduce. In turn, predators must evolve ways to overcome those defenses in ...
While the business and innovation ecosystem types are mostly based on parallels with the biology literature, the knowledge and entrepreneurial ecosystems have their origins in the economic geography literature. The knowledge ecosystem can be defined as a “… heterogeneous set of knowledge-intensive ...
Referring to the manifold studies and the long-term experiences of the restoration of near-natural ecosystems and traditional land-use types, respectively, examples from all over the world are outlined. Additionally to rewilding as a progressive approach to nature conservation, letting nature take care...
Beyond molecular-level test, based on gene-level ground truth, our method can bypass the inherent uncertainty from immunohistochemistry test. This work thus provides a noninvasive method to predict the molecular subtypes of breast cancer, potentially guiding treatment selection for breast cancer patients...
cotton INTRODUCTION A suite of morphological and physiological adaptations that have permitted different Gossypium taxa to flourish in a wide range of natural environments offer potential solutions to a host of challenges to cotton cultivation, but the genetic basis of many of these adapta- tions remai...
In recent years, a large amount of mgDNA ITS sequence data from environmental samples have been deposited in GenBank. These data have neither been linked to any specimens nor given any formal names to genus and species level (Taberlet et al. 2012; Herder et al. 2014; Hawksworth et al. ...
alpine flood plains and snowbeds. A total of 1146 plots met the selection criteria (Supplementary Fig.S1online), covering an elevational range from 268 to 3060 m a.s.l. In order to consider thermophilisation at different elevational zones separately, we assigned each plot to one of the zon...
