For scientists, for students or for the public? : the shifting roles of natural history museums [PDF]
, 2010 This article aims to discuss the main roles of natural history museums and to show how these purposes have evolved and adapted throughout the museums’ history, as a response to the development of natural sciences and societal change, from their creation ...

Experimental Physiology, EarlyView.Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

The Journal of Physiology, EarlyView.Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

The Journal of Physiology, EarlyView.Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Maximal exercise at high altitude does not exacerbate inflammation in the human brain
The Journal of Physiology, EarlyView.Abstract figure legend This study investigated arterial–internal jugular venous (IJV) exchange of cytokines in response to low‐intensity and maximal cycling exercise at sea level and following 6–8 days at 3800 m a.s.l. There was a shift towards net release of interleukin‐6 (IL‐6), interleukin‐8 (IL‐8), monocyte chemoattractant protein‐1 (MCP‐1) and ...

Deadly Anchor: Gender Bias under Russian Colonization of Kazakhstan, 1898-1908 [PDF]
We study the impact of a large-scale economic crisis on gender equality, using historical data from Kazakhstan in the late 19th – early 20th century. We focus on sex ratios (number of women per man) in Kazakh nomadic population between 1898 and 1908, in ...

Influence of a detailed model of man on proton depth/dose calculation [PDF]
, 1972 The development of a detailed radiation shielding model of man is discussed. This model will be used to plan for manned space missions in which sensitive human tissues may be subjected to excessive radiation.

Subterranean environments contribute to three‐quarters of classified ecosystem services
Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
