Habits and Preferences in Sunscreen Usage Among Healthcare Professionals in the UK.

Raising awareness about sun protection is an ongoing challenge. In 2018, a Survey Monkey questionnaire was distributed among healthcare professionals in the United Kingdom looking at their own habits of sunscreen usage. A total of 165 responses were collected.

Precisely timed regulation of enhancer activity defines the binary expression pattern of Fushi tarazu in the Drosophila embryo.

The genes that drive development each typically have many different enhancers. Properly coordinating the action of these different enhancers is crucial to correctly specifying cell-fate decisions, yet it remains poorly understood how their activity is choregraphed in time. To shed light on this question, we used recently developed single-cell live imaging tools to dissect the regulation of Fushi tarazu (Ftz) in Drosophila melanogaster embryos.

Extracting and characterizing protein-free megabase-pair DNA for experiments.

Chromosome structure and function is studied using various cell-based methods as well as with a range of single-molecule techniques on short DNA substrates. Here, we present a method to obtain megabase-pair-length deproteinated DNA for studies. We isolated chromosomes from bacterial cells and enzymatically digested the native proteins.
