Researchers report the origin and immunoregulatory function of monocytes

Non-classical monocytes were long thought to play a purely surveillance role in the immune system. With the aid of a novel marker (PD-L1), Ludwig-Maximilians-Universitaet (LMU) researchers in Munich have now shown that they are directly involved in the regulation of immune response.

Researchers see around corners to detect object shapes

Computer vision researchers have demonstrated they can use special light sources and sensors to see around corners or through gauzy filters, enabling them to reconstruct the shapes of unseen objects.

Perovskite solar cells tested for real-world performance—in the lab

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.

Using game theory to model poisoning attack scenarios

Poisoning attacks are among the greatest security threats for machine learning (ML) models. In this type of attack, an adversary tries to control a fraction of the data used to train neural networks and injects malicious data points to hinder a model's performance.
