Ancient Europeans Retained Dark Skin, Hair and Eyes Until the Iron Age, Claims New Study
A genetic study analysing 348 ancient DNA samples reveals that most prehistoric Europeans had dark skin, hair, and eyes well into the Iron Age. Although genes for lighter pigmentation appeared around 14,000 years ago, they remained rare until about 3,000 years ago. Lighter skin may have been advantageous for vitamin D production, while lighter eyes...

Researchers Identify RNA Precursors in Molecular Clouds Located in the Centre of the Milky Way
An international team of researchers have spotted traces of an organic class of molecules at the centre of the Milky Way which are precursor to molecules essential for life. It is believed that originally life was based on only RNA (ribonucleic acid) on Earth while DNA (deoxyribonucleic acid) and protein enzymes evolved later. RNA is capable of per...

Smoking Leaves Chemical Traces On DNA: Study
Tobacco smoke leaves its mark on DNA by changing a chemical code on the DNA molecule that can sometimes change gene activity, according to a new study. Some of these molecular changes revert to their original state when a smoker quits, but others persist in the long term, the researchers found. Experts have known for some time that smoking causes c...
