Breast-Fed Babies May Have Longer Telomeres, Tied to Longevity

There are many positive outcome when breast-feeding a baby during their first six weeks of life, for example a child will develop a healthier immune system. Studies have shown when babies are beast- fed they tend to have a longer telomeres. A telomeres is a structure that lies at the end of a chromosome and secures the genes from any harm. It has been proven that when an individual develop a shorter telomere there is an occurrence of a chronic disease during their adulthood, but individual with longer telomeres will have a longer and healthier life. Researchers are yet to conclude whether telomeres are developed when consuming breast milk during their first six weeks or these structures are already developed at birth.

Scientists Find Genes That Let These Bees Reproduce Without Males

The female African South honey bees can reproduce asexually. Normally, honey bees reproduce sexually but studies have shown that in a small area in the Fynbos Ecoregion, the female will leave their homes to take control of other colonies. The female Cape honey bees will produces offsprings of her own and begin to control of the hive as a queen bee or become worker bees within those colonies. Scientist have tested the genomes between the Cape honey bees and the typical honey bees and explained that African South bees produces only female offspring when they reproduces asexually. They farther explained that this occurs because without the male chromosome presented during meiosis then only the XX chromosome appears.
