New research led by King's College London (KCL) has discovered thousands of DNA sequences originating from ancient viral infections expressed in the brain.
Part of the ancient virus that infected human ancestors for millions of years still lurks in our DNA.
An unusual version of retrovirus that lies between genes involved in chemical reactions in the brain is found more often in addicts than the rest of the population.
Many strains of viruses that haunt humans today have evolved from ancient organisms and their existence may be the first time the Earth's first vertebrate group will live.
Scientists have discovered the history of Retrovirus - the virus that existed 30 million years ago, helping scientists better understand the evolution of today's viruses.
At least 8% of your DNA belongs to strange races and is made up of virus-derived pieces, not human. In fact, pieces of virus that often lurk within the genome of anything on Earth
French scientists are cautious when trying to revive a frozen prehistoric virus in Siberia.
New American scientists
A group of scientists from the French National Center for Scientific Research (CNRS) announced they had revived a giant but harmless virus buried deep in the permafrost in Siberia
Marijuana plants receive genes that encode proteins to synthesize cannabinoid active substances from ancient viruses, which have infiltrated the plant's DNA and are there to date.
