On using radon-222 and CO2 to calculate regional-scale CO2 fluxes [PDF]
Atmospheric Chemistry and Physics, 2007 Because of its ubiquitous release on land and well-characterized atmospheric loss, radon-222 has been very useful for deducing fluxes of greenhouse gases such as CO2, CH4, and N2O.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Interannual variability of vertical particle fluxes in the Ross Sea (Antarctica) [PDF]
Nature Conservation, 2019 This study presents new data on biogenic and terrigenous particle fluxes collected by an oceanographic mooring (Mooring A) deployed in the south-western Ross Sea (Antarctica) in the frame of the Italian Long-Term Ecological Research network (LTER-Italy).

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Estimating the carbon fluxes of forests with an individual-based forest model
Forest Ecosystems, 2017 Background Capturing the response of forest ecosystems to inter-annual climate variability is a great challenge. In this study, we tested the capability of an individual-based forest gap model to display carbon fluxes at yearly and daily time scales. The

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

A new calculation of atmospheric neutrino fluxes [PDF]
Astroparticle Physics, 1994 Abstract Atmospheric neutrino fluxes have been computed directly from recent measurements of muon momentum spectra in the stratosphere. The results agree to within about 15% with the previous calculations by Barr, Gaisser and Stanev by another method, although they predict a somewhat different variation of flux with geomagnetic latitude.

Molecular Oncology, EarlyView.Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Interpretation of the IBEX-Lo Observations of Energetic Neutral Atoms along the Voyager Trajectories
The Astrophysical Journal LettersThis Letter addresses a long-standing discrepancy between simulated energetic neutral atom (ENA) fluxes and Interstellar Boundary Explorer (IBEX) observations in the ∼0.02–0.1 keV energy range.
