Measurement of radon concentrations at Super-Kamiokande

, 1999
Radioactivity from radon is a major background for observing solar neutrinos at Super-Kamiokande. In this paper, we describe the measurement of radon concentrations at Super-Kamiokande, the method of radon reduction, and the radon monitoring system.

Connecting existing cemeteries saving good soils (for livings) [PDF]

, 2020
Background: Urban sprawl consumes and degrades productive soils worldwide. Fast and safe decomposition of corpses requires high-quality functional soils, and land use which competes with both agriculture and buildings.

Evidence from stable isotopes and Be-10 for solar system formation triggered by a low-mass supernova

, 2016
About 4.6 billion years ago, some event disturbed a cloud of gas and dust, triggering the gravitational collapse that led to the formation of the solar system.

New approaches to investigating the function of mycelial networks [PDF]

, 2005
Fungi play a key role in ecosystem nutrient cycles by scavenging, concentrating, translocating and redistributing nitrogen. To quantify and predict fungal nitrogen redistribution, and assess the importance of the integrity of fungal networks in soil for ...

Status and Prospect of Secondary Battery Technologies in Space Applications: Challenges and the Future

Batteries &Supercaps, Volume 9, Issue 5, May 2026.
Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

UNC45B Reduction With Aging: A Myofiber‐Intrinsic Promoting Factor for Sarcopenia

Aging Cell, Volume 25, Issue 5, May 2026.
Aging reduces Unc45b expression in fast‐twitch muscle, concomitant with reduction in muscle contractile capacity and muscle mass in mice. Unc45b deficiency initially reduces depolarization‐induced force, followed by a decline in fast‐twitch muscle mass in adult mice.

Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Discovery Prospects for a Supernova Signature of Biogenic Origin

, 2011
Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust.
