Quantum-nonlocality at all speeds
The phenomenon of quantum nonlocality defies our everyday intuition. It shows the strong correlations between several quantum particles some of which change their state instantaneously when the others are measured, regardless of the distance between them. While this phenomenon has been confirmed for slow moving particles, it has been debated whether nonlocality is preserved when particles move very fast at velocities close to the speed of light, and even more so when those velocities are quantum mechanically indefinite.

Bending Light for Safer Driving; Invisibility Cloaks to Come?
Optical cloaking allows objects to be hidden in plain sight by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In Journal of Applied Physics, researchers examined recent progress of developing invisibility cloaks that function in natural incoherent light and can be realized using standard optical components.
Brain Cell Membranes' Lipids May Play Big Role in Alzheimer's Progression
Links between lipid imbalance and disease have been established, in which lipid changes increase the formation of amyloid plaques, a hallmark of Alzheimer's disease. This imbalance inspired researchers to explore the role of lipids comprising the cellular membranes of brain cells. In Biointerphases, the researchers report on the significant role lipids may play in regulating C99, a protein within the amyloid pathway, and disease progression.
