Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
How can the same basic genome produce such different forms in the two sexes of a single species? It turns out one gene can encode for various things, depending on the order its instructions are read.
Maths is often a quiet contributor to problems in subjects like biology.
Rats were less able to find food after only three days on a diet high in sugar and saturated fat. So could a bad diet also be affect the human brain?
Every new batch of bees needs the equivalent of eight hectares of lavender fields to prosper.
In 1997, scientists announced they'd created a healthy sheep cloned from another ewe's mammary gland cell. Two decades on, the technique is being refined and applied to new challenges.
During bird irruptions, hundreds or thousands of a single species show up outside their normal territory. Most of what we know about irruptions comes from data collected by citizen scientists.
Modern medicine is increasing our lifespan. But as we survive diseases and live longer, more of us are succumbing to cancer.
Victorian attitudes influenced what scientists thought they were observing about sexual behaviors in the animal world. But modern techniques reveal the myth for what it is.
Four organisms that show nature isn't so easily categorised.
When art meets the biological sciences, living matter becomes the medium. From the chaotic beauty of smallpox to poems implanted in bacteria, Bio-art investigates the boundaries of life and death.
A new exhibition at MONA, curated by scientists, explores the biological and evolutionary origins of art. The show is spectacular - but it offers an overwhelmingly male perspective.
Move over, DNA profilers. Scientists are developing a potentially more powerful technique to identify criminals from their hair.
Humans can more easily tolerate tumours in large or paired organs than in small, critical ones. This could be why the latter have evolved more cancer-fighting mechanisms.
Scientists have uncovered the genetics that explain the snake's impressive length – and used the science to create extra-long mice.
Understanding the genetic origins of sharks' teeth could one day lead to new treatments for humans.
Scientists have discovered two new types of ants in the rainforests of New Guinea thanks to an advanced X-ray imaging technique.
Dolly the sheep died young with osteoarthritis, but new evidence shows early-onset diseases aren't inevitable for clones.
Our planet's huge range of environments has led some animals to evolve some bizarre but very useful features.
