New technology means accessing new information from ancient human remains, some which have been in collections for decades. Elizabeth Sawchuk

Ancient DNA is a powerful tool for studying the past – when archaeologists and geneticists work together

Ancient DNA allows scientists to learn directly from the remains of people from the past. As this new field takes off, researchers are figuring out how to ethically work with ancient samples and each other.
Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks. Terry Goss/Wikimedia

Sequencing the white shark genome is cool, but for bigger insights we need libraries of genetic data

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.
Evidence shows that the growth of air pollutants – as well as rising temperatures, increased rain and flooding – connect breast cancer with climate change. (Shnutterstock)

As the oceans rise, so do your risks of breast cancer

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.

Curious Kids: Why do people grow to certain sizes?

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.

Can Seabiscuit’s DNA explain his elite racing ability?

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.

What causes multiple sclerosis? What we know, don’t know and suspect

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 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. B. Prud’homme, J. Yamaguchi

In red and black, the genetics of ladybug spots

Where do the pretty colours of the harlequin ladybug come from? A single gene draws the colour patterns of this familiar insect.
