There may be more a natural way to reduce the use of pesticides but still save plants from attack -  by recreating a natural insect repellent based on smell. Scientists from Cardiff University…

Stem cells cling to feeder cells as they grow in petri dishes and it has been thought that this attachment occurs because feeder cells serve as a support system, providing stems cells with essential…

A proof-of-concept study in mice showed it is possible to prevent transmission of mitochondrial disease to children without resorting to controversial cytoplasmic transfer - "three-parent" IVF.…
