Scientists have uncovered the genetics that explain the snake's impressive length – and used the science to create extra-long mice.
We need to actively build a mother culture grounded in safety and acceptance.
An environment rife with shame is a fertile breeding ground for conflict: pitting mother against mother.
But I asked for green highlights!

There must be some evolutionary force acting to maintain this visual 'defect'.
There’s nothing that everyone wants in a partner. But there are characteristics most men or women find attractive.
We know a lot about why people choose different brands of dishwashing detergent. But when it comes to the processes behind choosing a romantic partner, science knows surprisingly little.
There’s a battle for resources going on in there.
Embryos greedily want more resources than their fair share. New research investigates how early in evolution their hormonal tactics arose.
Computers can be our prediction machines.

Scientists of all kinds turn to computer models to investigate questions they can't get at any other way. Here's how models work and why we can trust them.
Your attitudes to risk – from extreme sports to school rugby – are hardwired into you.

We've bred them into all shapes and sizes, but dogs haven't been around for long enough to have evolved beyond Canis familiaris.
The superbug MRSA (green) interacts with a human white cell.
The evolutionary history of antibiotic resistance suggests it may be impossible to develop resistance-proof antibiotics so what are our other options?
Just heard the news? Relax, it doesn’t mean you fancy your mum.

Science explains why people pick partners who look like their parents – without involving Freud.

Why hunter gatherers weren't as peaceful as you may think.
A very different nativity scene.
You might be surprised to hear that virgin births are possible - just not in humans. By the reason why remains an evolutionary mystery.
Sexual competition has made sperm the most diverse - and fascinating - cells in the animal kingdom.

Cats share some important genes associated with herbivores – this might explain their particular eating habits.
No, I said I love YOU more.
Humans as well as zebra finches go through hurdles to find their perfect partner – and this may better ensure the survival of any offspring.
Sometimes the audience can be a font of illuminating questions.
I sometimes forget that people can feel embarrassed listening to me talk about my research on sperm. But often those same people can also be a source of amazement and inspiration.
A great white shark captured off the coast of Mexico.
We used to think of sharks as primitive fish because the had cartilage instead of bones. Turns out there was a good reason why and it makes them anything but primitive.
Sex is not without its costs. Wouldn’t it be easier if you could just create a clone of yourself?
Imagine how easy life would be if you could produce offspring without a mate. Sexual reproduction is the most common mating system in the animal kingdom. But in many species, females do not require males…
Selfish, cooperative – or doesn’t understand the rules of the game?

Behavioral economists have revolutionized the standard view of human nature. No longer are people presumed to be purely selfish, only acting in their own interest. Hundreds of experiments appear to show…
The human Y chromosome has retained only 3% of its ancestral genes. So why’s it a shadow of its former self?

The Y chromosome, that little chain of genes that determines the sex of humans, is not as tough as you might think. In fact, if we look at the Y chromosome over the course of our evolution we’ve seen it…
