DNA testing for cocoa beans could fight slavery and child labour.
Alzheimer’s, like many diseases, has a genetic component.

Using a technique called admixture mapping, researchers can leverage the diversity of people with mixed ancestry to look for hard-to-find genetic risk factors for diseases like Alzheimer's disease.
The real message is how old you are when you first have sex and have your first child is controlled by a little bit of nature and a lot of nurture.
Determining the age of fish has been historically difficult, primarily involving lethal methods. A new DNA test solves this problem.
DNA can solve all sorts of mysteries, including the sometimes thorny question of paternity.
A lie about children's paternity back in 1700 means tens of thousands of South Africans today are using the wrong surname.
All 129 men who embarked on the Franklin expedition died. DNA analysis is being used to identify the remains.
129 officers and crew died during the 1845 Franklin Northwest Passage expedition. DNA analysis from their remains of members can reveal the identity of the men who perished during the journey.
An Afrikaner family from the 1930s. Scientific analyses are unpacking Afrikaners’ genetic origins.
Given the central role that ethnicity played and still plays in South African politics, it is good to have an unbiased estimate of Afrikaners' genetic history.
Anything that moves or processes tiny amounts of fluid is a microfluidic device.

Electronics are not the only technology to have been miniaturized. Using the strange behavior of fluids in tiny spaces, microfluidic devices are critical to medicine, science and the modern world.
A simple two-dimensional grid can convey a lot of information – whether making pictures with Lite-Brite or storing data in DNA.
DNA has been storing vast amounts of biological information for billions of years. Researchers are working to harness DNA for archiving data. A new method uses light to simplify the process.
Some long non-coding RNAs make it easier for cancer cells to multiply.
Long non-coding RNAs were long thought to serve no purpose. Now, researchers think differently.
If storing DNA for criminal investigations helps identity the perpetrators and eliminate the innocent, why don't we include samples from everyone?
Looking for bits of DNA at the University of Florida.
Technology that can identify stray bits of genetic material in the environment can help scientists monitor human and animal health.
A complete human genome, seen here in pairs of chromosomes, offers a wealth of information, but it is hard connect genetics to traits or disease.
The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.
Genetic ancestry tests may sound like a bit of fun, but in an era marked by increasing xenophobia, it's important to be aware of the interplay between genetics and ideas of race.
MRNA is an important messenger, carrying the instructions for life from DNA to the rest of the cell.

Recently in the spotlight for its role in the Pfizer and Moderna COVID-19 vaccines, mRNA is not a new invention. It's a crucial messenger molecule at work every day in every cell in your body.
Were starfish really the oldest relatives of vertebrates such as mammals?
Scientists used to believe that a group containing starfish and sea urchin were the closest relatives of vertebrates like humans. But new research challenges this idea.
If the same mechanism exists in humans, it may explain health differences in children conceived by older fathers.

So far, most vaccines in the US are mRNA vaccines. These represent a new technology and are likely to take over the vaccine world. But how do they work? What are their weaknesses? Five experts explain.
Gene-based vaccines had never been approved for humans before the coronavirus pandemic.

The coronavirus pandemic has driven a lot of scientific progress in the past year. But just as some of the social changes are likely here to stay, so are some medical innovations.
Genes that control blood type and are involved in inflammation have been associated with more severe disease.
