Evolution of sexual systems and regressive evolution in Riccia

New Phytologist, Volume 246, Issue 2, Page 769-784, April 2025.
Summary The genus Riccia is the most speciose of the Marchantiopsida, the complex thalloid liverworts. In contrast to the predicted ancestral liverwort and the majority of extant liverworts that are dioicous, most Riccia species are monoicous. Both the gametophyte and the sporophyte generations have undergone regressive evolution in Riccia, with the ...

The strength of organ, tissue, and body field effects determines the frequency of all neoplasia

Annals of the New York Academy of Sciences, Volume 1546, Issue 1, Page 11-22, April 2025.
Abstract In 1953, Danely Slaughter proposed the concept of field cancerization, or field effect, to explain the development of additional neoplasia of similar type. A recent theory (de Groen, 2022) states that all DNA is exposed to a constant source of damage, resulting in a constant rate of germline and somatic DNA mutations.

Galaxy assembly revealed by globular clusters

The Open Journal of Astrophysics
Many observable properties of globular clusters (GCs) provide valuable insights for unveiling the hierarchical assembly of their host galaxy. For the Milky Way (MW) in particular, GCs from different accreted satellite galaxies show distinct chemical ...

Verification of the Fusarium‐Increasing Properties of the Dominant Dwarfing Gene Ddw1 in triticale (×Triticosecale)

Plant Breeding, Volume 144, Issue 2, Page 151-158, April 2025.
ABSTRACT Dwarfing genes that are considerably reducing plant height are used in many cereals. In triticale, the rye‐derived dominant dwarfing gene Ddw1 was introgressed in commercial varieties. It has already been shown that this gene increases Fusarium head blight (FHB) susceptibility in one segregating population.

The neonatal mortality risk of vulnerable newborns in rural Bangladesh: A prospective cohort study within the Shonjibon trial

Tropical Medicine &International Health, Volume 30, Issue 4, Page 283-291, April 2025.
Abstract Objectives Preterm birth (<37 weeks), low birth weight (2500 g), small‐for‐gestational‐age (birth weight <10th percentile of a given reference), and large‐for‐gestational‐age (birth weight >90th percentile of a given reference) are indicators of vulnerable infants and risk factors for neonatal mortality. We estimated the prevalence and risk of

Cosmic Rays and the Askaryan Effect Reveal Subsurface Structure and Buried Ice on the Moon

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract We present the first full‐wavelength numerical simulations of the electric field generated by cosmic ray impacts into the Moon. Billions of cosmic rays fall onto the Moon every year. Ultra‐high energy cosmic ray impacts produce secondary particle cascades within the regolith and subsequent coherent, wide‐bandwidth, linearly‐polarized radio ...
