🚀🧊 Did you know #Mars’ north pole hides a massive, complex layer of ancient ice and sediments? Learn more from @nerozzi.it et al's dataset & article at doi.org/10.25422/azu... & doi.org/10.1016/j.ic.... Image: Nerozzi et al (2022). CC BY 4.0 #OpenData #OpenScience #PlanetaryScience #SpaceResearch
(a) BU radar facies and extent map, with location of the sample radar profile in panel c. Note that the diffuse facies associated with cavi unit materials make up most of the surface of the BU. “GL area” indicates the center of the region occupied by Gemina Lingula, “HL” indicates Hyperborea Lingula. (b) Comparison of BU lateral extent mapped in this and previous studies, with locations of radar profiles and images of the following figures. (c) Sample of SHARAD profile 1977101 showing examples of the sharp, mixed, and diffuse radar returns of the BU. This profile was depth corrected assuming a bulk water ice composition (i.e., ε’ = 3.1).

🌱💨Did you know taking soil samples can disturb the #soil and skew the results? Gil-Loaiza et al. developed a solution to this. Learn more from their dataset & article at doi.org/10.25422/azu... & doi.org/10.5194/bg-1.... Image: Gil-Loaiza et al. (2022) #OpenData #OpenScience #SoilHealth #SoilGases
Detailed schematic of sampling System 1 (UA) and System 2 (ARI). Column matrix gas concentrations were controlled by mixing cylinder gas with UZA using MFCs and delivering the custom gas mixture through the columns from bottom to top (dotted orange line). Probe sampling flow rates were controlled precisely using three MFCs to ensure that flow in and out of the probe was balanced (probe flow (blue lines) + dilution flow (red lines) is equal to total flow to analyzer (black lines)). Column headspace (atmospheric pressure) and control gas bypass (positive pressure) were controlled by MFCs at two points (dilution, total flow to analyzer), forcing the probe flow as a makeup flow (probe flow is equal to total flow minus dilution flow).

🌍 Did you know Earth’s surface still moves today because of ancient shifts in Earth’s inner structures? Calvelage et al. show more. See their dataset & article at doi.org/10.25422/azu... & doi.org/10.1098/rspa.... Image: Calvelage et al. (2024). CC BY 4.0. #OpenData #OpenScience #Tectonics
A graphic representation showing dynamic uplift and dynamic subsidence within an oceanic region from viscous stresses due to mantle upwelling and downwelling, known as dynamic topography (modified from [3]; K Czarnota 2022, personal communication). The seafloor deepens at a known rate as the ocean lithosphere cools and becomes older, shown here by its relative distance from the mid-ocean ridge. Dynamic topography is inferred in regions where the seafloor is anomalously shallower or deeper relative to the expected seafloor depth.

Fig. 1. a) Ultrafast laser stress figuring (ULSF) entails focusing an ultrafast laser at multiple depths in a mirror substrate, with coating on top (shown here) or bottom, depending on the coating. The stress induced by the laser spots bends the substrate to match the target shape. b) Process flow for applying ULSF to achieve a desired deformation of an optical surface. The stress calculator, recipe calculator, calibration procedure, and laser processing system are each described in the text.

Dorymyrmex bicolor engage in more social interactions than D. insanus. (A) Schematic of behavior method with pairs of ants filmed in a glass petri dish for 3 min and interactions coded in BORIS (Friard and Gamba, 2016). (B) Stills from recordings showing D. bicolor engaging in biting (left) and grooming (right) behaviors. In comparisons of nestmate interactions or non-nestmate interactions between species, D. bicolor interact more often than D. insanus (C). In comparisons of nestmate and non-nestmate behavior within species, D. bicolor non-nestmates display significantly more aggressive interactions (D) and significantly fewer affiliative interactions (E) than nestmates, an effect not detected in D. insanus. D. bicolor nestmates participate in antennation for longer duration bouts (F) and a greater amount of total time than non-nestmates (G); D. insanus nestmates and non-nestmates show comparable antennation bout duration and total time. (H) Dorymyrmex insanus display few trophallaxis events with no differences among nestmate or non-nestmate pairs, whereas D. bicolor nestmates engage in trophallaxis more frequently than non-nestmates. Statistical comparisons in (A–E,H) were made using a generalized linear model with a Poisson distribution followed by ANOVA and post hoc comparisons using Tukey’s Honestly Significant Difference. Statistical comparisons in F and G were made using pairwise Mann-Whitney U-test between non-nestmate and nestmate pairs of a species. *p < 0.05; ***p < 0.001; Color code for data point in (C–H): D. insanus cyan; D. bicolor blue.

Rhodopsin activation in lipid membranes entails a large influx of bulk water into the protein core. (A) Dark-state rhodopsin has a closed, dehydrated conformation of the 7-transmembrane helical bundle (30). (B) Open metarhodopsin-II conformation is adopted after retinal photoisomerization with outward-tilted TM6 (blue) and extended TM5 (green) helices following pH-dependent breakage of the Glu134–Arg135 salt bridge (31). (C) Large numbers of water molecules (~80–100) enter rhodopsin as determined by osmotic stress data for various-sized polyethylene glycols (PEGs). Smaller PEGs show smaller apparent water influx than more excluded large PEGs. The number of water molecules determined by the universal large osmolyte response is indicated by the dotted line. (D) Increase in virial coefficient ΔC for volume versus osmotic pressure accompanies rhodopsin photoactivation. Larger ΔC is determined in the exclusion limit of larger PEGs with the dotted line as the universal response. (E) Viewed from the intracellular side, dark-state rhodopsin is closed with residues colored by hydrophobicity (red, hydrophobic; white, hydrophilic). (F) The MII state shows an opened hydrophilic cavity (white) to accommodate the influx of bulk water which (G) widens as the C-terminal peptide of the G-protein (here Gi) is docked
