Bees;Petal Shapes: Heart gene therapy

EU states have voted in favour of a proposal to restrict the use of certain pesticides that have been linked to causing serious harm in bees. Patients in the UK have begun being enrolled into trials to see if an engineered virus can be used to heal their damaged and struggling hearts.Petals get their shape from a hidden molecular map within their buds that tells them how to grow. Scientists from the John Innes Centre and University of East Anglia discovered that these concealed maps are made up of patterns of arrows that act as instructions for how each cell in the bud should grow.
