Conceptual design of equipment to excavate and transport regolith from the lunar maria [PDF]
NASA hopes to have a manned lunar outpost completed by 2005. In order to establish the base, regolith must be excavated from the lunar surface. Regolith will be used as a source for life-supporting elements and as radiation shielding for the lunar ...

Advanced Science, EarlyView.ABSTRACT Periodontitis, a chronic inflammatory disease initiated and sustained by plaque microorganisms and host immune response, remains an intractable oral disease and a leading cause of tooth loss worldwide. Traditional mechanical debridement and adjunctive antibiotic or antiseptic therapy often shows limited efficacy due to the complex anatomical ...

Advanced Science, EarlyView.A targeted metabologenomic strategy integrating genomic and metabolomic hallmarks enabled the discovery of two new thioamides, thiogochangamides A and B, from bacteria. Their absolute configurations, previously unresolved within the thioviridamide family, were fully assigned through various chemical derivatizations and computational analysis ...

Advanced Science, EarlyView.TRF enriches Ruminococcus, a bacterial genus producing SCFAs, and activates the epithelial HIF‐1α signaling pathway. This mechanism protects the colonic mucosa from inflammatory insults in colitis models. Mechanistically, gut lactate production during starvation and refeeding mediates H4K12la, which increases SLC9A3 expression and creates an acidic gut

Advanced Science, EarlyView.Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity
Advanced Science, EarlyView.Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Design of a lunar oxygen production plant [PDF]
To achieve permanent human presence and activity on the moon, oxygen is required for both life support and propulsion. Lunar oxygen production using resources existing on the moon will reduce or eliminate the need to transport liquid oxygen from earth ...
