Transforming DIY Geiger Counter Kits into Muon Detectors for Education and Scientific Exploration
ParticlesAny Geiger counter can be used as an effective cosmic ray detector on its own. In fact, it is known that even in the absence of a radioactive source, the instrument detects what is known as background radiation, which consists of various types of ...

New Phytologist, EarlyView.Summary One‐carbon (C1) metabolism, centered on the universal methyl donor S‐adenosyl methionine (SAM), plays critical roles in biosynthesis, redox regulation, and stress responses across plants and microbes. A recently proposed photosynthetic C1 pathway links SAM methyl groups directly to RuBisCO‐mediated CO2 assimilation and integrates with nitrogen ...

Constraining Large Scale Structure Theories with the Cosmic Background Radiation
, 1998 We review the relevant 10+ parameters associated with inflation and matter content; the relation between LSS and primary and secondary CMB anisotropy probes; COBE constraints on energy injection; current anisotropy band-powers which strongly support the ...

On observations of the cosmic radiation background
The Astrophysical Journal, 1980 Extant models to explain the observed anisotropies in the microwave and x-radiation background have been of the clump type: the earth is falling toward a density enhancement of large scale in an otherwise homogeneous cosmology. We present here alternate models in which the anisotropies are true relics of the very early history of the universe, and in ...

Experimental Physiology, EarlyView.Abstract The current understanding of crew health maintenance is founded upon decades of physiological research conducted in terrestrial spaceflight analogues and in low Earth orbit, particularly on the International Space Station. However, as we progress towards the Lunar Gateway and interplanetary missions, it is imperative that the tools employed to

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Atacama Cosmology Telescope: Millimeter Observations of a Population of Asteroids or: ACTeroids
The Astrophysical JournalWe present fluxes and light curves for a population of asteroids at millimeter wavelengths, detected by the Atacama Cosmology Telescope (ACT) over 18,000 deg ^2 of the sky using data from 2017 to 2021.

Probing the statistic in the cosmic microwave background
, 2009 Kolmogorov's statistic is used for the analysis of properties of perturbations in the Cosmic Microwave Background signal. We obtain the maps of the Kolmogorov stochasticity parameter for W and V band temperature data of WMAP which are differently ...
