In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle

Conservation Biology, EarlyView.
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Early life stress and disruption of the ageing trajectory in female rats: Insights into the origins and mechanisms underlying the risk of hypertension

Experimental Physiology, EarlyView.
Abstract Menopause increases the risk of hypertension in women, yet the factors contributing to this important change remain unclear. Because early life stress has persistent and sex‐specific consequences on health, we hypothesized that ageing reveals the latent effects of neonatal maternal separation (NMS) on cardiovascular homeostasis in female rats.

Wireless Bioelectronic Modulation of Membrane Potential in Glioblastoma Using Carbon Nanotube Porins

Advanced Science, Volume 13, Issue 16, 18 March 2026.
A schematic illustrating glioblastoma cell membrane modulation using carbon nanotube porins (CNTPs) and an applied voltage. CNTPs enable ion flux leading to changes in membrane potential. This figure summarizes the concept of bioelectronic control of cell membrane voltage.

ClC‐2 Contributes to Hypotonicity‐Induced Adrenal Aldosterone Secretion

Acta Physiologica, Volume 242, Issue 3, March 2026.
ABSTRACT Aim The zona glomerulosa (ZG) of the adrenal cortex regulates blood pressure and electrolyte homeostasis through aldosterone production. In ZG cells, potassium and angiotensin II (Ang II) trigger calcium oscillations that drive aldosterone synthesis.

Ageing reveals the latent effects of early life stress on respiratory and metabolic function in female rats: Novel insights into the sex‐specific origins of sleep apnoea

Experimental Physiology, Volume 111, Issue 3, Page 1466-1482, 1 March 2026.
Abstract Sleep apnoea (SA) is ∼2 times more prevalent in men than women. However, this changes at menopause as the occurrence of SA increases and matches that of men. Menopause is a natural process, but it remains unclear why SA emerges only in a subpopulation of ageing women.

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting

Endometrial assessment in abnormal uterine bleeding: transvaginal ultrasound alone may not be good enough

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 79-88, January 2026.
ABSTRACT Objective To evaluate the proportion of optimal assessments of endometrial thickness (ET) achieved by transvaginal ultrasound (TVS) compared with a multimodal (MM) sonographic approach in women with abnormal uterine bleeding (AUB). Methods This prospective observational study was a subset of the EPI‐SURE study conducted between June and ...
