Ants have something similar to blood, but it's called haemolymph. Some insects use it in unusual ways. When threatened by a predator, blister beetles can squirt haemolymph from their knees.
Our eyes don't grow much at all – but when we're very young, we still need to learn how to see.
Lots of positive pregnancy tests this time of year.
Did you ever consider that human beings might have a breeding season? Birth seasonality exists – and has interesting implications for childhood disease outbreaks.
Generations of giraffes.
It can actually be very tricky to define a species, but in the 1900s, scientists found a pretty good way.
Mangroves growing strong.
Mangrove forests grow in the tidal lagoons of tropical coastlines and they could actually benefit from climate change. Here's what that means for us.

The mummichog is a little-known fish that has made significant contributions to biological knowledge.
Evolution is not just for living beings.
Artificial intelligence research owes a lot to biology and chemistry.
An inch-long bloodsucker on the hunt for a meal.
Yes, giant mosquitoes are a thing. They're specialized to wait out the dry times only to emerge from their eggs when high water provides the perfect larval environment.
The birds and the bees.
Having looked after chickens for generations, humans are pretty good at getting them to keep on laying eggs.
Sharks eating seagrass? Sounds fishy, but the reality is that animals don't conform to the strict categories we try to place on their diets.
Running around like a…
There was once a chicken called Miracle Mike who lived for 18 months without a head: it's all to do with nerves.
Fossa (Cryptoprocta ferox) at the Houston Zoo.
The fossa, Madagascar's largest predator, is a cat-like carnivore that eats everything from insects to lemurs. Because they are rare and elusive, scientists know very little about them, including how many there are.
Zebrafish are known for their black and gold stripes.
Zebrafish are known for their black and gold stripes, but researchers are still figuring out how pigment cells interact to form these patterns.
From wealth, to the natural world, to genes and intelligence, a podcast exploring the theme of inheritance.
Most animal groups adopted their shapes quickly but some kept evolving.

They hovered in the skies of the Earth 300 million years ago... The giant dragonflies will soon be the stars of the paleontology gallery of France’s Natural History Museum in Paris.
Down House: the home (and garden) of Charles Darwin.
Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.
New research on reversing ageing in human cells could be the first step to new anti-degenerative drugs.
It takes time to see which finding might be a golden egg.
Basic research can be easy to mock as pointless and wasteful of resources. But it's very often the foundation for future innovation – even in ways the original scientists couldn't have imagined.
