One way to tackle this violent crime is through DNA profiling.
Self-examination DNA collection techniques can help women bring the perpetrators of sexual violence to justice.
We previously thought mitochondrial DNA could only be passed on by mothers.
‘Amphy’ has features of both simple and more complex forms of life – and so can help us understand important steps in evolution.
The marine creature amphioxus allows scientists to explore some of the steps that took place as simple creatures evolved to become complex animals.
Eighty years ago, Seabiscuit trounced Triple Crown winner War Admiral.
The US went crazy for Seabiscuit when he won his famous 1938 match race against War Admiral. Now researchers are investigating the thoroughbred's DNA to see what made him such an unlikely success.
The chances of your genetic data being recorded by the state depend on who you are.
US Senator Elizabeth Warren recently released the results of a DNA test to support her claim to Native American ancestry.
The question of whether a person can "become" Aboriginal after discovering ancestry through a DNA test is more complicated in Australia.
Some Harlequin ladybugs,
Harmonia axyridis, have black elytra with two large red spots. Others have two additional red spots backwards, or are decorated with a dozen small red spots. Conversely, there are ladybugs with red elytra, decorated with 20 black spots. All these ladybugs belong to the same species.

Where do the pretty colours of the harlequin ladybug come from? A single gene draws the colour patterns of this familiar insect.
Determining the structure of the DNA was the beginning of the gene therapy journey.
Once genetic lesions for diseases such as cystic fibrosis and haemophilia were identified, the idea of replacing or correcting defective genes grew into what we now call "gene therapy".
Our risk of cancer is determined by a complex mix of genes, environment and lifestyle factors.

As we age, our DNA accumulates damage, which can increase our risk of developing
cancer. But our cells work hard to guard against cancer – new research explains how.
A three-banded clownfish (
Amphiprion ocellaris) navigates the anemones of the Andaman Coral Reef, India.
Our children all know the little clownfish Nemo, star of the Pixar film. But why does he have three stripes, rather than one or two? Developmental and evolutionary biology are revealing the answer.
From wealth, to the natural world, to genes and intelligence, a podcast exploring the theme of inheritance.
DNA evidence tracks the ancient history of the Jewish people.
New research is pinpointing how much genes influence the stability of educational achievement.
DNA knot as seen under the electron microscope.
Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.

How can there be boom in new species discoveries while others are dying out at unprecedented rates?
Like the day’s newspaper, the brain has a temporary way to keep track of events.
How do brains convert experiences into memories? New research explores the chain of events by focusing on what genes shift into gear when neurons are firing.
A healthy weight means a healthy heart.
Your weight during your youth could have an effect on your heart for the rest of your life.

DNA sequencing means a scientist can take a bucket of seawater and ID every fish in the area. Now we need a universal 'biobank' of samples to make a truly powerful environment monitoring tool.
New research could allow us greater control over what happens to genetically modified organisms once they're in the wild.

Separating children from their parents is not just a psychological stress, it's a DNA stress. Scientific research shows that early life stress may have irreversible effects on how DNA works in the cells of the body.
