Softening of DNA near Melting as Disappearance of an Emergent Property
, 2020 Near the melting transition the bending elastic constant, $\kappa$, an emergent property of double-stranded DNA (dsDNA), is shown not to follow the rod-like scaling for small length $N$.

Toxins, 2019 Most ribbon worms (phylum: Nemertea) are found in marine environments, where they act as predators and scavengers. They are characterized by an eversible proboscis that is used to hunt for prey and thick mucus covering their skin.

X-ray measurements of stresses and defects in EFG and large grained polycrystalline silicon ribbons [PDF]
, 1979 The Bond method was employed to measure the lattice parameter in an area of 0.4 mm in diameter of EFG Si-ribbons to an accuracy of + or - 0.00008 A. A Bond goniometer was built which included a goniostat with a special specimen holder to mount ribbons 1 ...

Identification of RAG-like transposons in protostomes suggests their ancient bilaterian origin
Mobile DNA, 2020 Background V(D) J recombination is essential for adaptive immunity in jawed vertebrates and is initiated by the RAG1-RAG2 endonuclease. The RAG1 and RAG2 genes are thought to have evolved from a RAGL (RAG-like) transposon containing convergently-oriented

Omen and Anti-omen: The Rabbinic Hagiography of the Scapegoat’s Scarlet Ribbon [PDF]
, 2016 This article proposes that the place and meaning of various objects among religious communities can be explored in terms of “hagiography,” that is, through the narratives constructed around sacred objects sometimes long after their physical disappearance.

Chromatin: a tunable spring at work inside chromosomes
, 2001 This paper focuses on mechanical aspects of chromatin biological functioning. Within a basic geometric modeling of the chromatin assembly, we give for the first time the complete set of elastic constants (twist and bend persistence lengths, stretch ...
