'Wasabi receptor' is snake's infrared sensor
Category: Animal Behaviour
SNAKES have a unique sensory system for detecting infrared radiation, with which they can visualize temperature changes within their immediate environment. Using this special sense, they can image the body heat radiating from warm-blooded animals nearby. This enables them to...

The evolution of manual dexterity
Category: Neuroscience
The unique capabilities of the human hand enable us to perform extremely fine movements, such as those needed to write or to thread a needle. The emergence of these capabilities was undoubtedly essential in human evolution: a combination of individually...

Who's a clever boy then?
Category: Animal Behaviour
Self-recognition was long believed to be unique to humans. However, it was established more than 30 years ago that the great apes are capable of recognizing themselves in the mirror, and more recently it has been found that dolphins and...

Nematodes see without eyes
Category: Animal Behaviour
The humble nematode Caenorhabditis elegans is a millimeter-long roundworm which eeks out its existence in the soil and feeds on bacteria. Because it lives in a dark environment, and lacks specialized light-sensing organs, the nematode has always been assumed to...

Synapse proteomics & brain evolution
Category: Neuroscience
When it comes to human brain evolution, it is often said that size matters. The human cerebral cortex is much larger than that of other primates, and therefore its expansion must have been a vital feature of human evolution. Researchers...
