Researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles penetrate the cell membrane enabling the drug uptake.

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration has now explored the effects of multiple thermal cycles on microstructures and interactions between different layers of perovskite solar cells. They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising strategies to increase the long-term stability of perovskite solar cells.

Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's structure with great potential for advanced optical communication systems. In addition, a new type of space-time duality is explored for powerful analogies bridging different fields of optics.

Tasmanian devils are already being released inside predator-proof sanctuaries in New South Wales, and rewilding advocates believe they could suppress feral cats and foxes across the continent
