Proposed pathway between intestinal glycerophospholipid production and memory enhancement: based on metagenomic and metabolomic analyses, Li et al. suggest that increased levels of Lactobacillus apis (and other Firm-5 species which similarly contain many genes for the PTS sugar transport pathway) will cause increased sugar metabolism, which will lead to the production of more glycerophospholipids; these glycerophospholipids are then transported into the hindgut and are rapidly secreted into the hemolymph (perhaps helped by an increase in mGlu2 receptors); they are transported to the brain via the bee’s open circulatory system, with attached metabolites, leading to improved structure and function of neural and synaptic membranes, thereby promoting better memory. Purple shapes: genes that positively correlated with long-term memory; rectangles: genes found in all three analyses (analyses based on genes mapped to the whole gut microbiota, Firm-5 and Lactobacillus apis). Ovals: genes found in whole gut microbiota and Firm-5 analyses. Rounded rectangles: remaining memory-correlated genes. Gray shapes: genes which did not correlate with long-term memory. Blue arrows: sugar metabolism. Red arrows: glycerophospholipid metabolism. Purple arrows: the increase or decrease of metabolites after Lactobacillus apis supplementation.

Habitual coffee intake may be a protective factor against Alzheimer’s disease; specifically, increased coffee consumption could contribute to slower cognitive decline potentially by slowing the rate of cerebral Aβ-amyloid accumulation, and in doing so, ameliorate the associated neurotoxicity from Aβ-amyloid-mediated oxidative stress and inflammatory processes.

This artist’s illustration depicts what Chu et al. think is happening in the binary system KPD 0005+5106. The data suggest the white dwarf (blue sphere) is blasting a companion object (brown and red object on right), which is either a low-mass star or planet, with waves of heat and radiation. The white dwarf is also pulling material from the companion into a disk around itself, which the artist shows in orange, before it slams into its north and south poles. This process is contributing to the destruction of the companion through powerful gravitational forces. Image credit: NASA / CXC / M. Weiss / ASIAA / Chu et al.
