Lepraria juanfernandezii , a new lichen species from the Southern Hemisphere
Plant and Fungal Systematics, 2019 Lepraria juanfernandezii is described as a new species. It differs from all other species of Lepraria by its aggregate thallus with sparse prothallus hyphae, the absence of a hypothallus, the presence of divaricatic acid and the absence of zeorin, and

A NEW SPECIES OF OLIGOLOPHUS [PDF]
The Canadian Entomologist, 1893 Very few Phalangids have been collected on our mountains, and so it is not surprising that a new species of a genus which in Europe lives in high altitudes should be found on Mt. Washington, New Hampshire. Early in September 1893, Mrs. Annie T. Slosson kindly sent me several vials of arachnids from the White Mts., and among them o vial from Mt ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Clypeus slightly convex, not sulcate, closely striato-punctate, sparsely clothed with short, pale pubescence. Supraclypeal area convex, shining and impuncatate medially, and with crowded punctures on the margins.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Plant and Fungal Systematics, 2019 A new species of Tetradesmus (Tetradesmus adustus) is described from desert soils of southwestern North America. The identification is based on phylogenetic analysis of data from nuclear (ITS2 rDNA) and plastid (rbcL, tufA) barcode markers.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
