- ... Three types of fossil fern fronds bearing sporangia with in situ spores are described from the late Eocene Pikopiko Fossil Forest, southern New Zealand. They are referable to the extant fern genus Thelypteris subgenus Cyclosorus (Thelypteridaceae) and an extinct fern of uncertain affinity. The matching of Thelypteris (Cyclosorus) macrofossils to the spore form taxon Laevigatosporites ovatus is rec ...

- ... Nosema ceranae is spreading into areas where Nosema apis already exists. N. ceranae has been reported to cause an asymptomatic infection that may lead, ultimately, to colony collapse. It is thought that there may be a temperature barrier to its infiltration into countries in colder climates. In this study, 71 colonies from Scottish Beekeeper’s Association members have been screened for the presenc ...

- ... Microscopy has greatly advanced our understanding of biology. Although significant progress has recently been made in optical microscopy to break the diffraction-limit barrier, reliance of such techniques on fluorescent labeling technologies prohibits quantitative 3D imaging of the entire contents of cells. Cryoelectron microscopy can image pleomorphic structures at a resolution of 3-5 nm, but is ...
