Want help interpreting test results, or deciding what tests to ask for? Want help navigating evidence, not be sold another protocol? Read so much that you are now overwhelmed & dont know where to start? Feel abandoned or dismissed by your healthcare provider, or been told there is nothing that can be done to help? In my own journey, I remember frantically trying to find answers & getting constantly dismissed by doctors. Looking back, I wish I had some guidance from someone.

Fun fact: a human egg is about 0.12 mm in diameter
ncbi.nlm.nih.gov/labs/pmc/art...
Depending on hair thickness, this is typically slightly bigger than the diameter of a human hair (somewhere around 0.075 mm), meaning our eggs are usually visible with the naked eye

Fun fact: the tongue is made up of 8 muscles (4 intrinsic, 4 extrinsic). Each muscle has small units of fibres with their own function; some act independently, others co-operatively. The fibres of these muscles create a complex latticework structure

Fun fact: unlike most marine animals, otters dont rely on blubber to keep warm. Instead they have the densest fur of mammals, with between ~25,000-165,000 hairs/cm² (depending on the body part)

Fun fact: barnacles use their giant penis to "smell" where a mate is and know where to poke their 🍆. Since they're hermaphrodites, everyone is fair game, sometimes leading to a kind of barnacle orgy

Ecology and Evolution of Phenotypic Plasticity in the Penis and Cirri of Barnacles - PubMed
Most barnacles are sessile, simultaneous hermaphrodites that reproduce by copulation. This is achieved through the extension of a muscular penis, famous for being the proportionally largest in the animal kingdom. The penis is a long cylindrical or conical organ, composed of a series of folded rings, …

Who gets counted in Long COVID research?

Our new paper shows that routine study inclusion rules change who gets represented, even among people already diagnosed with Long COVID.

A fuller medical record ≠ a more representative cohort. 🧪

As i said, i cant read the full text but the abstract concludes:

"psychogenic blindness seems to suppress visual information at an early neural stage"

And i just wonder if we are missing out on some fascinating neuroscience by labelling it psychogenic

Again, this was confirmed with VEP

This was confirmed with visual evoked potentials (VEP), i.e. objective evidence of cortical blindness

The patient also had dissociative identity disorder (DID), for which she received therapy

Fascinating case study:
link.springer.com/article/10.1...

Full text in German so i can only read the abstract, but it seems like a patient was diagnosed with cortical blindness - a type of blindness from the brain rather than a problem with the eyes 🧵

Fun fact: (in women) getting lots of hugs from their partner may be associated with lower blood pressure including during stress, which may be partially due to higher oxytocin (often known as the love hormone, though its more complicated than that!) levels
sciencedirect.com/science/arti...
More frequent partner hugs and higher oxytocin levels are linked to lower blood pressure and heart rate in premenopausal women
In animals, ventral stroking for >5 days increases oxytocin (OT) activity and decreases blood pressure (BP), but related human studies are few. Thus, …

Fun fact: ever notice you can often see the un-illuminated bit of moon, & wondered what is making it visible? 🌒

That would be Earthshine: light is reflected off the Earth onto the moon so we can see where the sun dont shine!
