Cathepsin B Regulates Ovarian Reserve Quality and Quantity via Mitophagy by Modulating IGF1R Turnover

Aging Cell, EarlyView.
Autophagy regulates ovarian reserve, with Cathepsin B playing a critical role in aging. Inhibition of Cathepsin B increases follicle count, enhances IGF1R–AKT–mTOR signaling and improves mitochondrial function without compromising fertility. This conserved mechanism suggests potential therapeutic strategies to delay ovarian aging and sustain fertility,

Antipolitical class bias in corruption sentencing

American Journal of Political Science, Volume 69, Issue 2, Page 701-717, April 2025.
Abstract Are corruption trials that involve the highest ranks in the public sphere and large private companies biased against some groups? Existing research predominantly focuses on corruption prosecutions of politicians, leaving unresolved the extent to which judges apply differential treatment when convicting and sentencing the political class ...

Mariner 9 photographs of small-scale volcanic structures on Mars [PDF]

Surface features on the flanks of Martian shield volcanoes photographed by Mariner 9 are identified as lava flow channels, rift zones, and partly collapsed lava tubes by comparisons with similar structures on the flanks of Mauna Loa shield volcano ...

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Studies of vesicle distribution patterns in Hawaiian lavas [PDF]

Basaltic lava flows are generally vesicular, and the broader facts relating to vesicle distribution have long been established; few studies have yet been made with a view to determining how and when vesicles form in the cooling history of the lava ...

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, EarlyView.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Understanding plaster production in Palaepaphos–Hadjiabdoullah, Cyprus, during the Cypro‐Classical period

Archaeometry, EarlyView.
Abstract This article discusses the results of analytical work on wall and floor plaster from a secular monument excavated on the plateau of Palaepaphos–Hadjiabdoullah (Cyprus). Excavated within the frame of the Palaepaphos Urban Landscape Project (PULP), funded by the University of Cyprus since 2006, the monument is an extensive multifunction workshop

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

Boreas, EarlyView.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

Ribbed moraines formed during deglaciation of the Icelandic Ice Sheet: implications for ice‐stream dynamics

Boreas, EarlyView.
This study focuses on the deglaciation dynamics in the northeastern sector of the Iceland Ice Sheet, by investigating transverse ridges, together with glacifluvial and ice‐marginal landforms. The main emphasis is on the transverse ridges, which are primarily interpreted as ribbed moraines – the first to be described in Iceland.

Strangeness content of the nucleon in quasielastic neutrino-nucleus reactions

, 2007
We present a systematic study of the sensitivity of quasielastic neutrino-nucleus cross sections at intermediate energies to the strange quark sea of the nucleon. To this end, we investigate the impact of the weak strangeness form factors on the ratio of
