We show how to double copy heavy quark effective theory (HQET) to heavy black hole effective theory (HBET) for spin s≤1. In particular, the double copy of spin-s HQET with scalar QCD produces spin-s HBET, while the double copy of spin-1/2 HQET with itself gives spin-1 HBET. Finally, we present novel all-order-in-mass Lagrangians for spin-1 heavy particles.

Salivary and pancreatic amylase are encoded by AMY1 and AMY2, respectively, which are located within a single genomic locus that has undergone substantial structural variation, resulting in varying gene copy numbers across species. Using optical genome mapping and long-read sequencing, Yilmaz, Karageorgiou, Kim, et al. achieved nucleotide-level resolution of this locus across different human populations, offering new insights into how copy number variation contributes to human adaptation.

Recent advancements in viral metagenomics and single-virus genomics have improved our ability to obtain the draft genomes of environmental viruses. However, these methods can introduce virus sequence contaminations into viral genomes when short, fragmented partial sequences are present in the assembled contigs. These contaminations can lead to incorrect analyses; however, practical detection tools are lacking.

Background: Crocetin is a multifunctional apocarotenoid natural product derived from saffron, holding significant promises for protection against various diseases and other nutritional applications. Historically, crocetin has been extracted from saffron stigmas, but this method is hindered by the limited availability of high-quality raw materials and complex extraction processes. To overcome these challenges, metabolic engineering and synthetic biology can be applied to the sustainable production of crocetin.

However, whether and to what degree L1 activity directly impacts genome integrity is unclear. Here, we apply whole-genome sequencing to experimental models of L1 expression to comprehensively define the spectrum of genomic changes caused by L1.
