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.

Macroeconomic effects of demographic aging in Austria. Bertelsmann Stiftung Country Sheet, December 2019 [PDF]

, 2019
According to projections, the working-age population in Austria is going to age in the next 30 years, but is expected to shrink only slightly starting in the mid-/ late- 2020s. The expected decline is by about 2% between 2018 and 2050 (see Fig. 1).

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

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.

The Timor green pigeon Treron psittaceus of eastern Indonesia and Timor-Leste may be on the verge of extinction

Oryx
The Timor green pigeon Treron psittaceus, endemic to Timor, Rote, and adjacent satellite islands (eastern Indonesia and Timor-Leste), is declining because of severe hunting pressure and forest conversion. During 2002–2025, we conducted > 1,400 field days

Declines in populations of Salix caprea L.during forest regeneration after strong herbivore pressure

Acta Societatis Botanicorum Poloniae, 2014
Communities of broadleaved forest subject to strong pressure from large herbivores underwent degeneration. The relief of this pressure led to regeneration of the community, in which an important role was played by the sallow Salix caprea and other light ...

Population decline in Lithuania

Architecture and the Built Environment, 2018
Since the 1990s, Lithuania lost almost one-quarter of its population, and some regions within the country lost more than 50% of their residents. Such a sharp population decline poses major challenges to politicians, policy-makers and planners. The aim of this study is to obtain more insight into the recent processes of socio-spatial change and the role

Zannichellia contorta [PDF]

, 2018
This species is native to southern, central and eastern Spain, with an old record from the Atlas Mountains in northern Morocco requiring confirmation. The species is very sensitive to eutrophication and deterioration of water quality.
