We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems at $z > 2$. Toward J2123-0500, we find $N$(HD) $= 13.84 \pm 0.2$ for a sub-DLA with metallicity $\simeq 0.5Z_{\odot}$ and $N$(H$_2$) = $17.64 \pm 0.15$ at $

At the basis of the regulation of the genetic code (DNA) in eukaryotes is its organization into nucleosomes. Nucleosomes modulate DNA accessibility through conformational dynamics like DNA breathing - the transient unwrapping of DNA from the nucleoso

Observations of H2 spectra in the line-of-sight of distant quasars may reveal a variation of the proton-electron mass ratio μ = m p ∕ m e at high redshift, typically for z > 2. Currently four high-quality systems (Q0347-383, Q0405-443, Q0528-250 a

Recently indication for a possible variation of the proton-to-electron mass ratio μ=mp/me was found from a comparison between laboratory H2 spectroscopic data and the same lines in quasar spectra. This result will be put in perspective of other spec
