Here the authors modify siderocalin to enhance iron excretion in urine, and demonstrate therapeutic efficacy in iron overload mouse models.

The sample taken from carbonaceous asteroid Ryugu and brought back to Earth by the Hayabusa2 spacecraft contains outer Solar System-derived materials uncontaminated by terrestrial processes. Even CI carbonaceous chondrites, despite their closeness to solar abundances, are not pristine.

Here the authors show that this trend is not consistent across hyperdiverse wildlife communities, as camera trap surveys in Southeast Asia show that responses depend on species traits and do not affect the temporal overlap of biotic interactions.

The authors show that astrocytes produce high levels of the adenosine receptor A2A in Alzheimer brains. Reducing the levels of astrocytic A2A boosted memory in young and aging mice and mouse models of Alzheimer disease, whereas activating a related molecular pathway impaired memory. Thus, astrocytes regulate memory and abnormal receptor activity in these cells may contribute to memory disorders.
