Scientists create a pattern of nanomagnets called an artificial spin ice that can control the orbital angular momentum of a scattered x-ray beam.
Figure 1: Two strategies for generating orbital angular momentum (OAM) in light. The left side shows a 1D-like microstructure, called a fork-dislocation hologram, which is commonly used to generate OAM beams in visible light. The right side shows a 2D nanomagnet array, called an artificial spin ice, which was used by Woods, Chen, and colleagues to generate x-ray OAM beams. Structural (charge) scattering generates even-order beams (red doughnuts), while magnetic (spin) scattering generates odd-order beams (blue doughnuts).Two strategies for generating orbital angular momentum (OAM) in light.

University of Eastern Finland to coordinate a €15M Horizon 2020 research project for sleep apnoea
Sleep Revolution is a multidisciplinary and international research and development project aimed at reforming the diagnostics and treatment of sleep apnoea. The European Commission recently granted the project almost 15 million euros of funding from the Horizon 2020 Framework Programme for Health, Demographic Change and Wellbeing.
The objective of the project is to revolutionise research, diagnosis, and treatment practices of sleep apnoea. To achieve this goal, the project will develop methods based on machine learning and artificial intelligence to assess the severity of, and the need for treatment in, sleep apnoea. A total of 37 research institutes, hospitals, and companies will participate in the project. The ultimate objective of the project is to draw up new internationa
