Brain strain: Blood flow and metabolism in environmental extremes
Experimental Physiology, Volume 111, Issue 11, Page 5010-5031, 1 November 2026.Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Ets2 Is an Activity‐Dependent Transcriptional Regulator of a Fast‐Twitch Muscle Program
The FASEB Journal, Volume 40, Issue 20, 31 October 2026.Ets2 is a transcription factor rapidly (24 h) upregulated in skeletal muscle by fast 150 Hz, but not slow 20 Hz, stimulation patterns. Ets2 selectively translocates to nuclei of slow soleus muscle when stimulated by fast‐patterned, but not slow‐patterned, activity. Ets2 binds to a consensus DNA sequence in the troponin I fast intronic enhancer (TnIFIRE)

On microgravity and biological process
Advanced Studies in Theoretical Physics, 2019 Certain biological processes could be directly related to physics, such as telomere shortening and the activation of the telomerase enzyme. Telomere shortening is a well-known process that sets the pace of life in every living being. On the other hand, the reason behind telomere lengthening in some cases is not as well understood.

Lunar and Martian gravity alter immune cell interactions with endothelia in parabolic flight
npj MicrogravityReturning to the moon and traveling to Mars represent the main targets of human space exploration missions within the upcoming decades. Comparable to microgravity, partial gravity in these destinations is assumed to dysregulate immune functions, thereby ...
