Maps of Bsal risk in the U.S. comparing pre- and post- action risk
Relative risk maps of combined Bsal risk, comparing (a) pre-action risk (2010–2015), to (b) risk after implementation of surveillance and of importation restrictions on over 200 salamander species. Relative risk scores were scaled to 2010–2015. (c) Change in relative risk score per county as proportion of pre-action risk.

View of Halema‘uma‘u at Kīlauea summit - July 2 2021
A view looking north into Halema‘uma‘u on July 2, 2021. Although eruptive activity has paused at the summit of Kīlauea, HVO geologists still monitor the lava lake and summit area regularly. Lava lake surface depths remain the same over the past few weeks.

Photomicrograph from a raccoon found sick and euthanized in Texas
Photomicrograph from a raccoon (Procyon lotor) found sick and euthanized in Texas, US. (A) A cluster of schistosome ova are present in the pancreas. Ova are thin-shelled and are not operculated. Each viable egg contains a miracidium (arrows). The ova are surrounded by infiltrates of eosinophils, macrophages, and lymphocytes. H&E stain.
