Optimism about the future of others is widespread even in the face of bad news — at least if the person is someone we care about. However, we can feel this optimism even for strangers if they possess a few admirable attributes, a new study by Yale and University of Oxford researchers suggests. (more…)
Camouflaged creatures can perform remarkable disappearing acts but new research shows that predators can learn to read camouflage.
The study, which used human subjects as predators searching for hidden moths in computer games, found that the subjects could learn to find some types of camouflaged prey faster than others.
The research was carried out by the University of Exeter and the University of Cambridge and is published in the journal PLOS ONE. Moths with high contrast markings – that break up the shape of the body, like that of a zebra or giraffe – were best at evading predation at the start of the experiment. However humans learnt to find these prey types faster than moths with low contrast markings that match the background, like that of a stick insect or leaf bug. (more…)
