Ancient solutions of geometric flows with curvature pinching
, 2018 We prove rigidity theorems for ancient solutions of geometric flows of immersed submanifolds. Specifically, we find pinching conditions on the second fundamental form that characterize the shrinking sphere among compact ancient solutions for the mean ...

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling
Angewandte Chemie International Edition, EarlyView.Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

Autophagy, 2013 These days, when we talk about the origin of a protein, or even a pathway, we are typically referring to evolutionary lineages based on nucleotide sequences. For example, is a particular protein's function conserved? How far back did it first appear? Are there homologs in higher eukaryotes?

Microbiology Spectrum, 2016 ABSTRACT Antibiotic resistance is an ancient biological mechanism in bacteria, although its proliferation in our contemporary world has been amplified through antimicrobial therapy. Recent studies conducted on ancient environmental and human samples have uncovered numerous antibiotic-resistant bacteria and resistance genes.

Detecting cryptic ghost lineage introgression in four‐taxon genomic datasets
Applications in Plant Sciences, EarlyView.Abstract Premise Hybridization and introgression are pervasive evolutionary forces that have played fundamental roles in shaping the diversity of wild and domesticated plants. Four‐taxon tests for introgression provide a reliable framework for detecting signatures of ancient introgression from genomic data, which have played an important role in ...

Four Departures in Mathematics and Physics [PDF]
, 2010 Much of Mathematics, and therefore Physics as well, have been limited by four rather consequential restrictions. Two of them are ancient taboos, one is an ancient and no longer felt as such bondage, and the fourth is a surprising omission in Algebra. The
