We can predict hair and eye colour with reasonable accuracy from DNA, but other characteristics are being investigated.
DNA of the male-determining Y chromosome has been completely sequenced end-to-end, and it’s just as weird as we expected. Will we finally be able to understand how it works?
The smallest chromosome in humans, the men-specific Y chromosome, has just been sequenced after considerable hurdles.
New research sheds light on the interconnected nature of the human genome and what this means for future gene therapies.
Maui officials have asked relatives to provide DNA samples to help identify victims of the Lahaina wildfires. Time and exposure to the elements, however, can make DNA retrieval from remains difficult.
Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.
In the largest study of its kind, researchers have used DNA from a 6,700-year-old cemetery in France to reconstruct the lives of everyday Neolithic people.
Jurassic Park was a technological breakthrough for film because of its use of CGI. It also revived an interest in paleontology and raised ethical questions about DNA use.
For many years women were blamed for a couple’s infertility. But it’s now known that male factor infertility contributes to about 50% of total cases.
Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
Biobanks collect and store large amounts of data that researchers use to conduct a wide range of studies. Making sure participants understand what they’re getting into can help build trust in science.
Researching family history is a popular hobby. But hobbyists can find themselves unearthing details of ancestors behaving badly or treated cruelly – or family secrets and trauma.
Evolutionary geneticist Jenny Graves loves classical choral music, but grew tired of its biblical themes. So she set out to write an alternative based in science.
Phosphorus is the most elusive element crucial for life as we know it – and we now have the first evidence there’s some available in the oceans of Enceladus.
Virgin motherhood is no myth – sharks, birds and lizards can hatch from unfertilised eggs.
One genetic study of over a quarter million people highlights the cognitive benefits of exercise, while another, based on 30 years of scientific literature, says the opposite. Who’s right and who’s wrong?
Genetics expert Jean Bennett explains how gene therapy is being used to treat certain forms of inherited blindness.
The genetic study challenges previous theories about the origins and culture of the Picts.
An article written for Time Magazine, but never published, could have rewritten the history of how DNA was discovered.
