A virus is essentially an information system (encoded in DNA or RNA) surrounded by a protective coat.
Humans have a deep history of viral infections, the evidence for which dates back to ancient DNA from Egyptian mummies.
Genomes don’t translate easily into an understanding of disease.
Big data is all well and good, but if we want medical breakthroughs, we'll need big theory too.
The tiny rotifer has thrived for millions of years without sex.
Rotifers are tiny creatures found in ponds or puddles and can reproduce without sex. The theory says they should not have survived so how have they done it?
How has a retrovirus survived intact within the human genome for millennia, and how has it affected us?
The link between season of birth and the risk of having allergies is well known. A new study sheds light on why this link exists.
DNA analysis reveals that there are three populations of Antarctic blue whales.

Antarctica's blue whales all feed in the same place. But a new genetic analysis suggests they are actually three separate populations that breed in different parts of the globe.
Scientists used to think that the 98% of human DNA that didn't encode proteins was junk. They don't think that anymore.
The cost-effectiveness and clinical utility of PGx tests is still uncertain.

When you enter a Chemmart pharmacy, it's hard to miss the posters and brochures promoting its “revolutionary myDNA test”.
Slowly giving up its secrets.
Many of the genes and transcripts associated with schizophrenia are only found in humans, which makes studying the disorder difficult. But scientists are slowly making progress.
The annual ‘Living Landscapes’ procession is aimed at raising awareness of the Cedarberg’s KhoiSan cultural heritage.
Human population groups worldwide are highly homogeneous genetically. They are in fact 99.5% similar and their anatomical features vary in an uncorrelated fashion over the landscape.
Sorting pupae of genetically modified mosquitoes before release to the wild.
Insecticides and mosquito nets only get you so far. Synthetic biologists are ready to take the battle against mosquito-borne disease to the level of DNA – which might spell the insects’ ultimate doom.
Research on how our lifestyles affect our genes raises the possibility of giving your future kids a better start in life before they're even born.
The most important lesson? Always read the small print.
Men can deny paternity in when women they are involved with fall pregnant as a way of punishing the women.
When men deny the paternity of children, many South African women feel like they have no recourse. Making DNA tests affordable and accessible could change this.
New research suggests how we could prevent genetically modified organisms from surviving - and potentially spreading - in the wild.

The International Summit on Human Gene Editing drew a distinction between editing an individual's body cells and editing germline cells that would pass changes to future generations. Does that make sense?
Is he really guilty if he had a genetic predisposition towards impulsive behaviour?
Biology is out of our control but can influence our behaviour. But should people be given shorter sentences because of their genes?
Gene editing allows us to eliminate any misspellings, introduce beneficial natural variants, or perhaps cut out or insert new genes.
Should the gathering of experts from around the world that's considering the scientific, ethical, and governance issues linked to research into gene editing ring alarm bells?
Genetic changes to embryos will not only affect the person that embryo becomes but also all their descendants.
While gene editing offers the exciting potential for disease therapies, using it on human embryos opens up a can of worms.
How 'junk' DNA threw a spanner in the works.
