Mass of human chromosomes measured for the first time
The mass of human chromosomes, which contain the instructions for life in nearly every cell of our bodies, has been measured with X-rays for the first time in a new study led by UCL researchers.
For the study, published in
Chromosome Research, researchers used a powerful X-ray beam at the UK s national synchrotron facility, Diamond Light Source, to determine the number of electrons in a spread of 46 chromosomes which they used to calculate mass.
Arielulus pipistrelles (once included within
Pipistrellus), the Silver-haired bat
Nycticeius) (Roehrs
If serotines, butterfly bats and evening bats
do form a clade, the names Eptesicini and Nycticeini (or Nycticeiini) are both available: Nycticeini Gervais, 1855 very much has priority (Eptesicini wasn t used - I think - until published by Volleth & Heller (1984)), but Roehrs
et al. (2010) noted that more effort will be required to resolve the position of
Nycticeius [and what impact it might have] on the nomenclature of this clade (p. 1084) [the relevant part of the cladogram is shown here: if you need help, see the article on the vesper bat cladogram].
