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.
Scientific evidence shows overwhelmingly that people across the world are genetic refugees from Africa.
Despite science refuting the existence of different human races, people have used "race" throughout history to divide and denigrate certain people while promoting their claims of superiority.
To whom is she more closely related?
How many times do people make the comment about which parent a child takes after. So what does genetics say?
New forms of life are discovered in high-tech ways that leave yesterday’s natural history collections in the dust.

Forget the pith helmet and butterfly net. Discovering biodiversity now is much more about metagenomics and the 0's and 1's of digital databases.
You’ve come a long way, baby.
The how and the when of dog domestication are fairly settled. As for the where: now DNA says Fido traces his roots back to wolves in Central Asia that lingered around people's camps millennia ago.

The new 'science play' Photograph 51 is hot on the heels of a host of others, including Stoppard's The Hard Problem. Why are audiences attracted to these right now?

A new study has looked at the 'father effect' in epigenetics.
A DNA string. The genomic revolution is upon us.
The discovery made by three Nobel Prize winning chemists is one of biology's most important safeguards against imperfection in DNA.
You’d be in bad shape if your cells couldn’t fix DNA issues that arise.
Cells must repair the thousands of bits of DNA damage they incur every day. These cellular mechanisms fend off cancerous tumors, and cancer researchers are working to harness their power.
Tomas Lindahl, pictured here in the lab, along with Paul Modrich and Aziz Sancar, received the Nobel Prize for Chemistry.
The recipients of this year's Nobel Prize for Chemistry showed that DNA is far from static. Rather, it is bombarded by damaging forces, but our bodies know how to repair these precious strands.
