The secret behind coral reef diversity? Lots of time.

Strap on a diving mask and fins and slip under the crystal-clear water near a coral reef in Indonesia, Papua-New Guinea or the Philippines, and you'll immediately see why divers and snorkelers from across the world flock ...

Barn swallows may indeed have evolved alongside humans

The evolution of barn swallows, a bird ubiquitous to bridges and sheds around the world, might be even more closely tied to humans than previously thought, according to new study from the University of Colorado Boulder.

Tiny polyps save corals from predators and disease

In a new study published today in Proceedings of the Royal Society, scientists show how tiny hydrozoans, polyps smaller than one millimeter and commonly found in dense colonies on the surface of hard corals, may play a role ...

A warbler's flashy yellow throat? There are genes for that

Birds get their bright red, orange and yellow plumage from carotenoid pigments—responsible for many of the same bright colours in plants. But how songbirds turn carotenoids into the spectacular variety of feathered patches ...

Stick insect's propulsion joint discovered

The stick insect is a popular model organism in biological research for gaining a better understanding of insect walking movements. The advantage of the stick insect is that the structure of its body parts and nervous system ...

Medical imaging helps define Moa diet

Medical scanners and the same software used to assess building strength after the Canterbury earthquakes, have revealed new information about the diet and dining preferences of New Zealand's extinct moa.

Mathematics adds to understanding human disease

Researchers at the University of Melbourne have developed an energy-based mathematical modelling technique to build models of the complex biochemical systems within the human body.
