Rock solid proof of alien life? Scientists claim fossilized algae inside meteorite

Fossilized algae recently discovered inside a Sri Lankan meteorite could finally prove the existence of extra-terrestrial life, claim the authors of the new paper. In a recently published article in…

Generational inheritance of DNA methylation. Although spontaneous rates of genetic mutations are well understood, the rates of epigenetic variation in DNA methylation have remained a mystery until now. Using the plant Arabidopsis thaliana (depicted in the center), generational variation in DNA methylation was identified in five lineages separated by 30 generations of growth as indicated by the methylated pink Cs and the unmethylated green Cs

Are genes our destiny? ’Hidden’ code in DNA evolves more rapidly than genetic code

A “hidden” code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of…

Brain Cells Made from Urine

Human excreta could be a powerful source of cells to study disease, bypassing some of the problems of using stem cells, such as the risk of developing tumors and difficulties…

‘Junk DNA’ Drives Embryonic Development

An embryo is an amazing thing. From just one initial cell, an entire living, breathing body emerges, full of working cells and organs. It comes as no surprise that embryonic…

DNA: The Cosmic Serpent

Some biologists describe DNA as an “ancient high biotechnology,” containing “over a hundred trillion times as much information by volume as our most sophisticated information storage devices.” Could one still…
