Stem Cells hit the news again in April as the first human heart was constructed using them. The Minnesota-based team created the organ using donated hearts that were stripped down to the collagen "scaffolding", then injected with stem cells, which specialised into heart cells in response to the structure they were injected into. While this technology is very far away from being able to be used in a clinical setting, this might open some doorways into stem cell transplants.
Meanwhile in Japan, scientists have given mouse stem cells a specific combination of nutrients that has stimulated them into maturing into a functional retina: something to lookout for in the future for treatment of blind people.
The early Spring months also brought us news that mobile phones may be killing bumble bees, insects on which many crops and flowering plants lean on to survive. The research caused controversy in the bee-studying world, however, and many are skeptical about it, saying that there needs to be more research into air pollution and agriculture's effects on the creatures. There was no doubt about the need for research, though: the UN has already said that humans need to change their behavior in order to help bees survive, as we are so dependent on them.
In other science: the Extreme Light Infrastructure gets given the go-ahead by the European Commission. This is a collection of 3 lasers, each designed to emit pulses of greater power than has ever been used by human civilisation in order to try and break down vacuum itself.
