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.

I applaud the #EUCancerPlan *BUT* caution: putting #meat 🥩 (a nourishing, evolutionary food) in the same box as 🚬 to solve a contemporary health challenge, would be basing policy on assumptions rather than robust data.

#FollowTheScience yes, but not just part of it!

1/ Granted, some studies have pointed to ASSOCIATIONS of HIGH intake of red & processed meats with (slightly!) increased colorectal cancer incidence. Also, @WHO/IARC is often mentioned in support (usually hyperbolically so).

But, let’s have a closer look at all this! 🔍


2/ First, meat being “associated” with cancer is very different from stating that meat CAUSES cancer.

Unwarranted use of causal language is widespread in nutritional sciences, posing a systemic problem & undermining credibility.

3/ That’s because observational data are CONFOUNDED (even after statistical adjustment).

Healthy user bias is a major problem. Healthy middle classes are TOLD to eat less red meat (due to historical rather than rational reasons, cf link). So, they

4/ What’s captured here is sociology, not physiology.

Health-focused Westerners eat less red meat, whereas those who don’t adhere to dietary advice tend to have unhealthier lifestyles.

That tells us very little about meat AS SUCH being responsible for disease.

The entire discussion around Facebook’s disclosures of what happened in 2016 is very frustrating. No exec stopped any investigations, but there were a lot of heated discussions about what to publish and when.


In the spring and summer of 2016, as reported by the Times, activity we traced to GRU was reported to the FBI. This was the standard model of interaction companies used for nation-state attacks against likely US targeted.

In the Spring of 2017, after a deep dive into the Fake News phenomena, the security team wanted to publish an update that covered what we had learned. At this point, we didn’t have any advertising content or the big IRA cluster, but we did know about the GRU model.

This report when through dozens of edits as different equities were represented. I did not have any meetings with Sheryl on the paper, but I can’t speak to whether she was in the loop with my higher-ups.

In the end, the difficult question of attribution was settled by us pointing to the DNI report instead of saying Russia or GRU directly. In my pre-briefs with members of Congress, I made it clear that we believed this action was GRU.
