Astronomers have found strong evidence of a massive planet (or planets) — the first planet(s) in a circumtriple orbit — in a hierarchical triple star system called GW Orionis (GW Ori). This ALMA image shows the shadow of the innermost ring on the rest of the circumtriple protoplanetary disk around GW Orionis. Image credit: ALMA / ESO / NAOJ / NRAO / University of Exeter / Kraus et al. GW Ori, also known as HD 244138 and HIC 25689, is located...

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.
