It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

Neural networks taught to recognize similar objects on videos without accuracy degradation
Andrey Savchenko, Professor at the Higher School of Economics (HSE University), has developed a method that can help to enhance image identification on videos. In his project, a network was taught by a new algorithm and can now make decisions on image recognition and classification at a rate 10 times faster than before. This research was presented in the paper "Sequential three-way decisions in multi-category image recognition with deep features based on distance factor" published in Information Sciences.

Newly discovered immune cells at the frontline of HIV infection
Researchers at The Westmead Institute for Medical Research have discovered brand new immune cells that are at the frontline of HIV infection. Known as CD11c+ dendritic cells, these new cells are more susceptible to HIV infection and can then transmit the virus to other cells.

Pressure difference and vortex flow of blood in heart chambers may signal heart dysfunction
Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to heart failure.

PSI imaging helps with rocket launches
Rockets from the European Space Agency (ESA) fly into space with support from the Paul Scherrer Institute (PSI). Imaging carried out at PSI in cooperation with Dassault Aviation ensures the quality of certain components of the Ariane 5 and Vega launch vehicles. With the help of the neutrons generated at the neutron source SINQ, PSI researchers are screening so-called pyrotechnic components that are installed in the ESA rockets. These components, which act like fuse cords and igniters, ensure, among other things, that the booster rockets are dropped at the right hundredth of a second. The Ariane launch on 20 June took place with components that had been examined at PSI.

Enhancing face recognition tools with generative face completion
Researchers at the USC Information Sciences Institute (ISI) in California have recently carried out a study investigating whether completing obstructed faces using artificial neural networks (ANN) can improve the accuracy of face recognition tools. Their study originated from the IARPA Odin research project, which is aimed at identifying true and false faces in images, ultimately to enhance the performance of biometric authentication tools.

Artificial intelligence learns to recognize nerve cells by their appearance
Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.
