A biological pacemaker is one or more types of cellular components that, when implanted into certain regions of the heart, produce electrical stimuli that mimic that of the body’s natural pacemaker cells. Somatic gene transfer, cell fusion, or cell transplantation provide a way to realize it as somatic reprogramming strategies, which involve transfer of genes encoding transcription factors to transform working myocardium into a surrogate sinoatrial node, are furthest along in the possibilities.
Giordano Bruno, or Iordanus Brunus Nolanus (1548–1600), was an Italian Dominican friar, philosopher, mathematician, poet, and cosmological theorist, born in the Kingdom of Naples.

The Indo-European Languages (IELs) are a family of several hundred related tongues and dialects. There are about 445 living IELs with over two-thirds (313) of them belonging to the Indo-Iranian Branch (IIB). The most widely spoken IEL by native speakers are Spanish, English, Hindi, Portuguese, Bengali, Russian, Persian, and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an IEL natively, by far the highest of any language family.
