Fun fact: peregrine falcons dive at ~200 mph, making them the fastest known animal. At such high speeds, air pressure can damage their lungs; to counter this they have little boney cones in their nose, similar to a jet engine

Fun fact: emerging evidence suggests we taste sweet more intensely in the morning and this has nothing to do with our blood sugar or insulin but does track well (seemingly causally) with a key fullness & body weight regulating hormone, leptin

Diurnal variation of human sweet taste recognition thresholds is correlated with plasma leptin levels - PubMed
This synchronization of diurnal variation in leptin levels and sweet taste recognition thresholds suggests a mechanistic connection between these two variables in humans.

Fun fact: cancer cells (in a petri dish) can hijack the mitochondria from immune cells via physical nanotubes. this depletes the immune cells of energy and may help the cancer cells grow

Intercellular nanotubes mediate mitochondrial trafficking between cancer and immune cells - Nature Nanotechnology
Cancer cells adopt a series of strategies to evade the immune response mounted by the organism against them. Here we find that tumour cells can hijack mitochondria from immune cells by forming physica...

Fun fact: platelets are often seen as just plugs to help stop bleeds. However they store & release many things (eg inflammatory proteins, neurotransmitters), & the way they work has been described as similar to circulating neurons

Fresh Evidence for Platelets as Neuronal and Innate Immune Cells: Their Role in the Activation, Differentiation, and Deactivation of Th1, Th17, and Tregs during Tissue Inflammation
Recent studies suggest that in addition to their common function in the regulation of thrombosis and hemostasis, platelets also contribute to tissue inflammation affecting adaptive immunity. Platelets...

We can argue all day about the specifics of the trial, but fundamentally ME was NOT properly screened for and was NOT excluded during screening. This wouldn't happen in other diseases, it shouldn't happen with ME

Imagine justifying that by saying "participants gave informed consent" when they were not told there were no oncologists in the team nor that the intervention went against clinical guidelines, & when the information given did not actually explain the full scope of potential risks

Imagine running a cancer trial with ZERO oncologists on the team, doing something that is known to be ill-advised to cancer patients, then justifying it by saying "we stuck to our trial registration, got ethical approval, and with our poor assessments we saw no harm"

Fun fact: Many people have heard of ghrelin as THE hunger hormone, but emerging evidence suggests insulin-like peptide-5 is also a hunger hormone.

We know loads of fullness hormones but we have not been as successful finding hunger hormones
