When two substances are brought together, they will eventually settle into a steady state called the thermodynamic equilibrium. In new research, a team of physicists at Aalto University wanted to disrupt this state to see what happens; they subjected combinations of oils with different dielectric constants and conductivities to an electric field. An image of a typical non-equilibrium state comprising active filaments, random filament networks and...

Several lines of study suggest that peripheral metabolism of amyloid beta (Aß) is associated with risk for Alzheimer’s disease. In blood, greater than 90% of Aß is complexed as an apolipoprotein, raising the possibility of a lipoprotein-mediated axis for Alzheimer’s disease risk. Lam et al. report that genetic modification of C57BL/6J mice engineered to synthesize human Aß only in liver has marked neurodegeneration concomitant with capillary dysfunction, parenchymal extravasation of lipoprotein-Aß, and neurovascular inflammation.

This Hubble image shows a giant star called AG Carinae. The color image was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This processed image, based on observations taken in July 2017, shows the two moons of the asteroid Kleopatra and its two moons, AlexHelios and CleoSelene. The moons are difficult to see in the raw images -- which were taken with the SPHERE instrument on VLT -- owing to glare around the asteroid, inherent to this kind of adaptive-optics observations.
