Scientists Create First Cloned Human Embryo

  Scientists have made an embryonic clone of a person, using DNA from that person’s skin cells. In the future, such a clone could be a source of stem cells,…

Designing Life: Should Babies Be Genetically Engineered?

  The increasing power and accessibility of genetic technology may one day give parents the option of modifying their unborn children, in order to spare offspring from disease or, conceivably,…

Scientists use DNA to store MP3, holds 2.2 petabytes per gram

. Further exploring the role biological processes could one day play in the evolution of technology, researchers from the European Bioinformatics Institute claim to havesuccessfully encoded 154 Shakespeare sonnets and an MP3…

Discovery of quadruple helix DNA could lead to cancer breakthrough

Scientists at the University of Cambridge reported Sunday that they have discovered quadruple helix DNA inside human cells by creating synthetic molecules that seek it out — raising the potential…

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…

Gene Mutations Began Showing Up In Last 5,000 Years Of Human Evolution

In a world that’s more than 4 billion years old, humans have only existed for a fraction of that—roughly 200,000 years. In those 200,000 years of existence, not a lot…

‘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…

University of Illinois chemists found that DNA can shape gold nanoparticle growth similarly to the way it shapes protein synthesis, with different letters of the genetic code producing gold circles, stars and hexagons. (Credit: Li Huey Tan, Zidong Wang and Yi Lu)

Oh, My Stars and Hexagons! DNA Code Shapes Gold Nanoparticles

DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA’s code can similarly shape metallic structures. The team…

Does DNA Emit Light?

Are humans really beings of light? I get lots of suggestions for stories, and I really appreciate them. But some of them are too good to be true. An example…

Human Origins: The Literal Creation of Mankind at the Hands of You-Know-What

Then God said, “Let us make man in our image, after our likeness; … So God created man in his own image, in the image of God he created him;…
