Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks.
Why do scientists spend so much time and money mapping the DNA of species like white sharks? Single studies may offer insights, but the real payoff comes in comparing many species to each other.
16p11.2 deletion or duplication syndrome occurs in three out of every 10,000 people.
Genetically engineered mice are invaluable for learning about human disease.
When geneticists create mice with special traits, there is no way to be sure that they will be inherited by the offspring. But a new genetic tool called a gene drive may fix the problem.
Evidence shows that the growth of air pollutants – as well as rising temperatures, increased rain and flooding – connect breast cancer with climate change.
Most cases of breast cancer are related to environmental causes. When we talk about climate change, we must not forget this part of the story.
Scientists edge closer to truly personalised medicine thanks to advances in genome sequencing.
Erectile dysfunction can take the light out of men’s lives.
Discovering a genetic basis for erectile dysfunction that is linked to Type-2 diabetes will make it easier to identify those at risk – and novel treatments.
Wagyu cattle for scale.
An Australian steer named Knickers broke the internet this week. The heavyweight Holstein-Friesian weighs as much as a small car, but genetically speaking he's within the normal range (just).
We previously thought mitochondrial DNA could only be passed on by mothers.
Why does it cost so much to put a tea in a pot of hot water, anyway?
How did you start today – tea or coffee? Or neither? A study of more than 400,000 men and women links specific genes for tasting bitter flavours like caffeine with hot beverage consumption.
Genetic research on human behaviour has long been linked with eugenics and continues to attract interest from far-right groups.
Children grow up to look somewhat like their parents.
Every human carries an instruction booklet with a very special code, called DNA. Our eyes cannot read the code, but our bodies can. The code tells our body what to do and how to look.
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.
People exposed to low levels of sunlight are more likely to have MS than those who live in warm climates.
Young women are disproportionately affected by multiple sclerosis, a disease where the body attacks the brain, scrambling communication to the rest of the body. Here's what we know about the causes.
Some American Indian tribes, including the Navajo Nation, have moratoriums on genetic testing.
Why is Elizabeth Warren's DNA test so controversial with Native American groups? Two Indigenous geneticists explain the history and science behind the debate.
You can blame your parents for poor exam results…to an extent.

Genetics play a large role in how well someone does at university.
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.
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.

A new Science Gallery Melbourne exhibition offers a set of reflections, calculations and speculations that engage with ideas about the perfect body, mathematical precision, quantum physics and a post-human world.
