Towards Iron Biofortification of Banana (Musa spp.): A Comparative Study of Fruit Mineral Micronutrient Concentrations and Phylogenetic Insights Into Iron Homeostasis

Food and Energy Security, Volume 14, Issue 3, May/June 2025.
ABSTRACT Iron deficiency anemia (IDA) is alarmingly prevalent in sub‐Saharan Africa, where populations often rely on nutrient‐poor staple crops as their primary energy source. The East African highland banana (EAHB), a staple for millions in Uganda and most of East Africa's highlands, contains insufficient iron to meet dietary needs.

JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk

The Astrophysical Journal
We present MIRI Medium-resolution Spectrograph observations of the large, multi-gapped protoplanetary disk around the T Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9–25.5 μ m toward the inner ∼1 au in the disk ...

Circadian regulation of key physiological processes by the RITMO1 clock protein in the marine diatom Phaeodactylum tricornutum

New Phytologist, Volume 246, Issue 4, Page 1724-1739, May 2025.
Summary Phasing biological and physiological processes to periodic light–dark cycles is crucial for the life of most organisms. Marine diatoms, as many phytoplanktonic species, exhibit biological rhythms, yet their molecular timekeepers remain largely uncharacterized.

The enviroments of T Tauri stars

The Astrophysical Journal, 1983
The environments of T Tauri stars are probably determined by the interaction of a stellar wind with matter which is falling toward a newly formed star. As shown by Ulrich, the steady infall of cool gas with angular momentum toward the star leads to a density distribution with rhoproportionalr/sup -1/2/ inside a radius r/sub d/ and rhoproportionalr/sup -

The Self‐Magnification of British Leaders: Prime Ministers’ Perceptions and Projections of their Powers and Roles in the Postwar Era

The Political Quarterly, Volume 96, Issue 2, Page 340-355, April/June 2025.
Abstract Within the extensive literature on the powers and constraints of British prime ministers, there has been little comparison of the extent to which the premiers themselves have perceived or projected a personal entitlement to determine government policy.

A Multiwavelength, Multiepoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. I. HST Far-UV and Near-UV Spectra

The Astrophysical Journal
The classical T Tauri star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion processes, which can dictate future stellar evolution and planet formation, a multiepoch ...

Measuring the Magnetic Field of the Classical T Tauri Star TW Hydrae [PDF]

, 2005
We present infrared (IR) and optical echelle spectra of the classical T Tauri star TW Hydrae. Using the optical data, we perform detailed spectrum synthesis to fit atomic and molecular absorption lines and determine key stellar parameters: Teff = 4126 ...

Some resolutions on T Tauri stars [PDF]

Symposium - International Astronomical Union, 1990
This symposium is dedicated to the results of studies of flare stars. The necessity of the detailed analysis of observational data on flare stars follows from the very simple fact, that until now the theory has not found for the answer to the question: why the young stars of low luminosity are flaring.

Analytic and numerical models of the 3D multipolar magnetospheres of pre-main sequence stars

, 2011
Traditionally models of accretion of gas on to T Tauri stars have assumed a dipole stellar magnetosphere, partly for simplicity, but also due to the lack of information about their true magnetic field topologies.
