Marine macroalgae are widely used indicator species for monitoring environmental radioactivity. Empirical studies have demonstrated a range in radionuclide transfer coefficients, or concentration ratios (CRs), between taxonomic groups, however the CR values used for dose estimation assume that macroalgae are a homogenous group, represented by a single CR. This study demonstrates the presence of a taxonomic signal in macroalgae CRs for multiple anthropogenic and naturally occurring radionuclides (Cs, Am, Pu, Po) based on a collation of available data.

Article Synopsis
  • - The study presents a measurement of astrophysical tau neutrinos using 9.7 years of data from the IceCube observatory, identifying seven candidate events with energies between 20 TeV and 1 PeV.
  • - Convolutional neural networks were used to analyze simulated event images, helping to estimate the parent tau neutrino energy to be around 200 TeV while facing a background of about 0.5 events primarily from non-tau astrophysical neutrinos.
  • - The results confirmed the presence of astrophysical tau neutrinos at a 5σ significance level, aligning with existing IceCube measurements and theoretical predictions regarding neutrino flux and oscillations.

Article Synopsis
  • Microbial Fuel Cells (MFC) can generate energy using biomass from dead plants and plant-related chemicals like sugars and cellulose, as well as algae.
  • The systems function symbiotically, where algae enhance the cathodic chamber conditions, leading to increased oxygen production and a stronger electrical output.
  • MFCs can utilize a variety of plant-derived materials including compost, dead algae, and more, emphasizing their versatility in bioelectrochemical applications.

With the rapidly expanding global nuclear industry, more efficient and direct radiological monitoring approaches are needed to ensure the associated environmental health impacts and risk remain fully assessed and undertaken as robustly as possible. Conventionally, radiological monitoring in the environment consists of measuring a wide range of anthropogenically enhanced radionuclides present in selected environmental matrices and using generic transfer values for modelling and prediction that are not necessarily suitable in some situations. Previous studies have found links between taxonomy and radionuclide uptake in terrestrial plants and freshwater fish, but the marine context remains relatively unexplored.
