It's a very different perspective when we realize that our bodies consist of an entire ecology of bacteria and viruses that are also passed to our ancestors. Mammals rear their young and as a consequence transfer the microbiome and virome to their offspring.

 What does it mean to treat our individuality as ecologies? We are all ecologies existing in other ecologies. Nature is constantly performing a balancing act across multiple scales of existence.
There are bacteria and viruses that are unique to your ancestry as that of your own DNA. They have lived in symbiosis with your ancestor and will do so for your descendants.
It is an empirical fact that the microbiome in our stomach can influence not only our own moods but also our metabolism and thus our weight and health.
It is also intriguing to know that brains evolved out of stomachs and that our stomachs contain hundreds of millions of neurons. Humans can literally think with their gut.
But when we think with our gut or if our gut is influenced by the microbiome and virome, then we can't really claim that we act completely independently of the ecology we carry.
When we claim that the mind is inextricably connected to the body, do we also mean that it is also connected to the microbiome and the virome. That is organisms that have evolved independently of our DNA?
When we speak of the epigenome that expresses traits based on its environment, are we not also talking about the environment that also includes the microbiome and virome?
This also places in question the tired debate of nature vs nurture. Can we truly create a crisp boundary between the two ideas. Is there really such a thing as a core nature now that we realize that it's more than our DNA that generates who we are?
We are the holistic sum of a milieu of processes, processes that our epigenome is in constant interaction with. These processes include our local ecology and the much wider culture that we live in. This happens at a multitude of scales and thus under an unimaginable complexity.
The discovery of quantum mechanics revealed the fuzziness of the most elementary of things. It also revealed the inescapable subjectivity of reality. The discovery of the complexity of biology also has revealed both but at the scale of our individuality.
We are walking ecologies analogous to the fuzziness and subjectivity intrinsic in every atom that we consist of. It is irreducible complexity and subjectivity all the way down.

AGI Significance Paradox: As progress accelerates towards AGI, the number of people who realize the significance of each new breakthrough decreases.

Why is it that you can boil a frog in water without it jumping out if you gradually increase the temperature?

The problem for the frog is that it does not have the internal models to realize that there is a change in the water temperature. A cold-blooded creature like the frog has its temperature regulated by the external environment.

To recognize change, an agent must have an internal model of reality that is able to recognize this change. Unfortunately, a majority of the population do not have good models of human general intelligence.

In fact, even the simplistic dual-process model of system 1 and system 2 is not very well known.

Genes are to Evolution, Memes are to Culture, Dicenes are to General Intelligences.

Open-ended generative processes like evolution and human culture have a thing that is replicated and propagated by the process. For evolution, these are known as genes. For culture, these are known as memes.

It became obvious to me that there isn't an equivalent for individual brains. Is there something that is equivalent to this in general intelligent systems or biological brains?

I have come up with a term that describes these. The word I've invented is 'dicene'. This word is inspired by C.S. Peirce's dicent sign or dicisign. It is the combination then of dicent and gene, and thus dicene.

But why dicene over so many other possibilities like schemes, themes, intuitions, patterns, schemas, embeddings, attention, habits, explanations, ideas, meanings, representations, concepts, analogies, and lekta?

It is astonishing that most of cognitive science ignores an obvious reality. That there are two kinds of humans.

Tomasello has a very credible hypothesis that what distinguishes humans from the great apes is the inclination towards shared intentional behavior. What is innate is the disposition and like personalities, it is what defines our cognition as we grow.

If cognitive preference is so critical in cognitive development then why is it that we seem to have completely ignored the difference in cognitive preferences between men and women?

Humans are that species of primates that wandered out into the savannah. The savannah is different enough from a dense jungle to exert the evolutionary pressures that encourage the development of planning and forecasting skills.

Furthermore, human infants required a disproportional amount of effort to rear. This meant the specialization of roles between women who were responsible for rearing offspring and men who were responsible for bringing home the bacon. Failure in either implied death.

Programming in abstractions is very different from a system that is capable of its own 'abstracting'. But what does abstracting mean? We only know of its inputs and outputs, but we fail to describe its inner workings.

I like this short video about living in space. This is because it makes you realize the gaps in your knowledge when you turn off something (i.e. gravity) that you have always assumed to be present.


Perhaps we can understand 'abstracting' better if we turn of many assumptions that we unconsciously carry around. Perhaps we need to get rid of the excess baggage that is confusing our thinking about abstraction.

Turning off gravity and living in space is a perfect analogy. We somehow have to turn off a cognitive process to understand the meaning of abstraction.

The first step to divorce ourselves from our habitual cognitive processes is to realize the pervasiveness of 'noun-thinking' .

Chess may be a good analogy for explaining the difference between a descriptive model of reality and a generative model of reality.

A descriptive model of chess will describe the rules (i.e. initial setup, allowed moves, points per piece, objectives). This tells you how a chessboard might evolve and also narrows the combinations of realistic chess positions.

In contrast, a generative model involves the actual gameplay between competing players that follow the rules. It generates new styles and patterns. It establishes new strategies and tactics. It generates new openings, middle gameplay, and end game tactics.

A generative model is an evolutionary model that leads to emergent behavior. As a consequence, a master of chess is able to recall the layout of chess positions in a real game in an instant, yet is unable to remember pieces placed in random positions.

That is because causality is present in the movements of pieces in a chessboard. An intuitive system like the human mind is able to capture that causality as a means to understanding and recall.

“Should I give them more fluid?”

Extremely common question during AKI referrals from junior docs.

⛔️ Fluid management is tricky, often misunderstood, & can cause huge iatrogenic harm ⛔️

We try to convey important principles in THREAD 👇

#tipsfornewdocs #medtwitter #tweetorial

Currently too often patients with high creatinine are given too much IV fluid, driven by an AKI ➡️ fluid reflex

We’ve seen 7 litres be given in one shift.

Medics & surgeons, juniors & seniors, it seems everyone loves to reach for extra IV fluid (especially if urine output poor)

Why does huge volume IV fluid ‘resuscitation’ consistently occur?

Lots of reasons, including FALSE beliefs:
🛑 IV fluid always “treats AKI”
🛑 Hypotension = hypovolaemia
🛑 Lactate >2 means fluid deficiency
🛑 Septic patients are very hypovolaemic

The rule with IV fluids and AKI is to remember this 5 word phrase:

💥 💥 Aim for euvolaemia, then stop💥 💥

Fluid status is like Goldilocks - hypovolaemia is bad for the kidneys BUT excess volume is also harmful for renal function and will cause other complications too.

It is easy to say “target euvolaemia” - but we agree it is more difficult to do!

Fluid status assessment is certainly made harder by a belief that we must only rely on a snapshot assessment of examination features which are NOT specific / sensitive / reliable to elicit like.…

ECTOPIC PREGNANCY

A woman just lost her life due to ectopic pregnancy!

It's a pregnancy in which the embryo attaches outside the womb. It can be life-threatening.

But we can save lives by helping educate women on our Timelines with this.

THREAD 🧵


In the human body, a fertilized egg hardly survives outside the womb. If allowed to grow, it may damage nearby organs & cause severe blood loss.

The bulk of ectopic pregnancies occur in/along the Fallopian tubes.

Some in the ovaries, cervix or a random location in the abdomen.


The usual symptoms of ectopic pregnancy a woman may experience esp. in early pregnancy are;

* Abdominal pain
* Vaginal bleeding, &
* Amenorrhea (missing your period)

Other pregnancy symptoms like breast fullness & occasional nausea may be there too.

But the common DANGER SIGNS of ectopic pregnancy that may signify rupture are;

🔴 Rigid abdomen

🔴 Severe abdominal pain

🔴 Shoulder tip pain, &

🔴 Signs of shock such as cold hands & feet.

With these signs, immediate medical attention is needed to save the woman's life!

Your chances of having an ectopic pregnancy are higher if you have;

1. Previous ectopic pregnancy

2. STI's like gonorrhea

3. Fertility treatments like IVF*

4. Fallopian tube surgeries

5. Pregnancy while using an Intrauterine Contraceptive Device

6. Smoking history! 🚭

Want to include the menstrual cycle in your scientific work, but aren't sure how to do it? My lab (@katjaschmalen) have just published an article on best practices for observational studies of the cycle! Thread below! 🧵

Despite decades of research on the menstrual cycle, empirical studies have not adopted consistent methods for operationalizing the menstrual cycle, resulting in confusion in the literature and limited possibilities to conduct systematic reviews and meta-analyses.

Below, I summarize this "how to" article, and relay some of the key points!

PARTICIPANTS: All participants should be naturally-cycling people with ovaries (remember that they are not necessarily "women"! 🏳️‍⚧️ ⚧).

We provide a Reproductive Status Questionnaire with rules for identifying naturally-cycling people (current function of the sexual organs and hormonal/other medications that stop the cycle).

SRI THIRUNARAYANA PERUMAL, MELKOTE (KAR)

Known as Dakshin Badri, Thiru Narayanapuram is one of the four famous Swayambu Kshetrams, the other three being Srirangam, Kanchipuram and Tirupati.
The presiding diety is Cheluva Narayana Swamy/ Selva Pillai/ Rama Priyan.


Once, Sri Rama gave his aradhana murthi of Sri Ranganatha, to Raja Vibhishana on his request. So he was left without a murthi for his daily pujas. Brahma is said to have provided the murti of Selva Pillai to Rama who later passed this on to his sons, Lava and Kusa.


When Kusa’s daughter married a Yadava prince, this murthi moved to the lunar dynasty from solar.

It is said that the utsav murthi got the name Selva Pillai due to Sri Ramanuja.
Once, a Sultan took away this murthi and Sri Ramanuja went in its search to the Sultan’s palace.

How to Get Rich (without getting lucky):

Seek wealth, not money or status. Wealth is having assets that earn while you sleep. Money is how we transfer time and wealth. Status is your place in the social hierarchy.

Understand that ethical wealth creation is possible. If you secretly despise wealth, it will elude you.

Ignore people playing status games. They gain status by attacking people playing wealth creation games.

You’re not going to get rich renting out your time. You must own equity - a piece of a business - to gain your financial freedom.

Hello, my name is Gal,
I am an Israeli citizen, and I want to convey this urgent message to the world: Contrary to what you are told, Israel has not "returned to normal" in any way >>

2/ Moreover, despite the desire to create a setting as if there was a full and normal routine here - the Israeli Ministry of Health JUST RECOMMENDED TODAY TO EXTENT THE DECLARATION OF A “STATE OF EMERGENCY” in Israel >>

3/ to which is the foundation for coercion, violation of basic rights, severe discrimination under a "green mark (pass)", prolonged closure (Of about 5 months overall) and a lot of undemocratic and not “routine" restrictions. >

4/ If the situation in Israel had "returned to routine thanks to the astounding success of vaccines" then the "state of emergency" would not have continued.

5/ In fact, since the beginning of the "vaccination project" there has been only more intimidation and in many ways - even though the closure has been lifted, much more coercion.
