Demographic viability of populations of \u3cem\u3eSilene regis\u3c/em\u3e in midwestern prairies: relationships with fire management, genetic variation, geographic location, population size and isolation [PDF]
, 1998 We studied the demographic viability of populations of a long-lived iteroparous prairie perennial, Silene regia, in relation to management regimes, population sizes, geographical region (Ohio and Indiana vs.

Advanced Science, EarlyView.Time‐resolved SAXS reveals how physiologically relevant metal ions shape the earliest conformational responses of monomeric α‐synuclein. Fe3+ induces rapid compaction, Cu2+ generates heterogeneous and partially folded ensembles, while Mn2+ and Zn2+ cause only modest changes.

Advanced Science, EarlyView.Liposomal nanoconfinement converts the hemicyanine photosensitizer RhM from Type‐II to Type‐I photodynamic therapy (PDT) while enhancing photothermal therapy (PTT). The RhM‐R837@Lip nanoassembly efficiently generates superoxide (O2•−) and hydroxyl radicals (•OH) to kill tumor cells and achieve tumor ablation.

Environmental restoration and biological contamination: ecological and legal aspects [PDF]
Biotemas, 2005 Environmental restoration is a pressing current need. However, protected areas have been exposed to biological contamination risks because the traditional techniques of restoration frequently use exotic species. This causes some concern, since biological

Bioenergy Cropping Reduces the Spatiotemporal Scaling of Soil Bacterial Biodiversity
Advanced Science, EarlyView.Consistent with patterns observed in plant and animal communities, soil bacterial communities exhibit significant species–time–area and phylogenetic–time–area relationships independent of nested structure. Bioenergy cropping significantly reduces the spatiotemporal scaling rates, particularly in sandy loam soils.

Advanced Science, EarlyView.Protein complexes like KIBRA‐PKMζ are crucial for maintaining memories, forming month‐long protein traces in memory‐tagged neurons, but conventional RNA‐seq analysis fails to detect their transcript changes, leaving memory molecules undetected in the shadows of abundantly‐expressed genes.

Possible detection of atmospheric bioaerosol via LiDAR: a wavelength-based simulation study
Asian Journal of Atmospheric EnvironmentThis study explores potential of LiDAR technology to rapidly detect aerosolized biological terror agents in the atmosphere. It assesses the application by simulating extinction coefficients and the Ångström exponent at various wavelengths (266, 1064 ...

“Son tutti morti”. Human Extinction and the Apocalyptic Imaginary in Giacomo Leopardi
Cahiers d’Études ItaliennesThis article investigates the speculations on and depictions of human extinction in Giacomo Leopardi’s writings, with particular emphasis on the Operette morali (1824–1832).

Determining species expansion and extinction possibilities using probabilistic and graphical models
Ekológia (Bratislava), 2015 Survival of plant species is governed by a number of functions. The participation of each function in species survival and the impact of the contrary behaviour of the species vary from function to function. The probability of extinction of species varies
