Are giant sinkholes in China’s karst mountains havens or traps for the rare plants that inhabit them? A new study finds they are both—offering refuge from heat and drought while gradually eroding the evolutionary potential of an endangered tree.

With the aid of physical forces – in this case, sound – it is possible to actively steer the formation of engineered tissue. For example, sound waves can be used to create functional vascular networks with blood vessel-like structures in vitro. Scientists at the Center for Molecular Biology of Heidelberg University have demonstrated this through their methodology for acoustic manipulation. The team headed by Junior Professor Dr Daniela Duarte Campos also defines quality requirements for generating complex multi-cell-type vascularized 3D tissue that is, for example, relevant for biomedical studies.
