Scientists composed of an international team spearheaded by the University of Michigan has presented a new type of photoreceptor in animals that is 50 times more efficient at capturing light than the rhodopsin in the human eye. This photoreceptor is just the third to be found in animals, specifically a family of taste receptors in invertebrates.
A team of researchers from 11 institutions in five countries recently discovered a DNA fossil of a human-infecting parasite. However, that they were found in certain species of tropical birds suggests that these parasitic worms transferred from birds to humans several million years ago.
New 3D recordings of neural activity in a nematode shed light on how neurons coordinate action and perception in animals.
