Resource quantity affects infection success and impacts of a microsporidian on hosts
Oikos, Volume 2026, Issue 2, February 2026.Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...

Scanning of Vehicles for Nuclear Materials
, 2013 Might a nuclear-armed terrorist group or state use ordinary commerce to deliver a nuclear weapon by smuggling it in a cargo container or vehicle? This delivery method would be the only one available to a sub-state actor, and it might enable a state to ...

Small, Volume 22, Issue 8, 6 February 2026.Intranasal (IN) delivery of PEGylated PLGA nanoparticles (NPs) loaded with oxytocin (OT) (OT‐NP‐PEG) is investigated as a strategy to enhance OT transport to the brain for treating autism and other neuropsychiatric disorders. The optimized NP formulation demonstrates appropriate physicochemical characteristics, improved stability, and enhanced mucosal ...

Mixing in the Solar Nebula: Implications for Isotopic Heterogeneity and Large-Scale Transport of Refractory Grains [PDF]
, 2008 The discovery of refractory grains amongst the particles collected from Comet 81P/Wild 2 by the Stardust spacecraft (Brownlee et al. 2006) provides the ground truth for large-scale transport of materials formed in high temperature regions close to the ...

Who Pulled the Trigger: a Supernova or an AGB Star?
, 2010 The short-lived radioisotope $^{60}$Fe requires production in a core collapse supernova or AGB star immediately before its incorporation into the earliest solar system solids. Shock waves from a somewhat distant supernova, or a relatively nearby AGB star,

Tropicalization Enhances Mangrove Methane Emissions to the Atmosphere
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Organic‐rich mangrove soils release CH4, partially offsetting the climate benefits of high organic carbon sequestration. However, the local and global drivers and variability of mangrove CH4 emissions remain poorly understood. Here, we quantify water‐atmosphere CH4 emissions over hourly, daily, and weekly time scales in an Australian mangrove ...

A system for online beam emittance measurements and proton beam characterization
, 2018 A system for online measurement of the transverse beam emittance was developed. It is named $^{4}$PrOB$\varepsilon$aM (4-Profiler Online Beam Emittance Measurement) and was conceived to measure the emittance in a fast and efficient way using the multiple
