A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

In order to investigate the change of internal structure of porous media caused by arsenic deposition, X-ray difference micro-tomography was used to characterize the distribution of arsenic aggregates within porous media by scanning a series of arsenic samples prepared in the laboratory and arsenic-rich fluvial sediments from the Río Loa in Chile. After image processing, background noise in the tomograms was reduced and arsenic information was enhanced. Then the processed images were used to generate 3D spatial distribution datasets of arsenic in the media. Tools like Avizo6 and Blob3D were used to reconstruct and visualize the 3D datasets. 3D visualization showed that arsenic accumulated in the pore space and grain surface; arsenic aggregates of different sizes had distinctly different morphologies, which small aggregates tended to be spherical while big aggregates were relatively flat. These results show that difference micro-tomography can be used to observe the pre- and post-deposition structure of porous media, without any destruction to the samples.
