The epigenetics of memory, inherent knowledge if you will, is so dang cool to me. Things like the studies done on the Danish famine post Nazi occupation during WWII help show this building in certain ways within people https://www.journalofpsychiatricresearch.com/article/S0022-3956(10)00346-8/fulltext
But man, some of the conferences I've been to lately have showed some pretty amazing "knowledge" sharing at rudimentary levels from generation to generation. Seems obvious this would occur - how do fawn's know to sit still or to bleat for mom, or where to search for milk or what not... That cant be taught in the first 5' of life, yet the know...
Similar things are seen in people and emerging research there is really cool.
Sea slugs are not people, but seeing this was, interesting... So figured it would be a neat post for fellow nerds here.
I don't think they " Know" in the real sense of the word. ( to be conscious of aware of, through observation, inquiry or by information learned) They do behave in ways that are conducive to survival but not from an intention to do so. The successful traits persist and the unsuccessful (if relevant to survival) get killed off.
What is interesting to me is the persistence of abnormalities that occasionally pay off. (Two heads are not one of them) That is, within the framework of a complex genetic code that provides the framework of existence at all. Such depth of information in the DNA is awesome and mysterious. How that came to be and why it continued is one of those mysteries/miracles...

In case a PETA member ever try's to tell you that eating protein, especially a lot, leads to bone loss... Yet another paper telling them to go pound sand, and eat a cow ;)...
The human gut microbiome is some pretty amazing, and emerging inquiry. Wild stuff. This is an interesting review of some info from one major research project, which is done in a fairly novel way.
One particularly interesting thing to me, was a notation that post antibiotic use the gut microbiome was reduced (as expected since antibiotics kill bacteria - of various types pending the medication), but, was more diverse. Diversity is good, and while that certainly would not be a reason to take antibiotics... since you can get a more diverse gut microbiome via eating more variety of plants... But it was interesting that taking antibiotics does not decimate the gut microbiome.

I was reading about the longest (60 years long and still going) Predetor-Prey study ever done,.. on Island Royale in Canada,.. interesting read about Wolves and Moose.

I had always thought corals were the nurseries for fish,.. this article indicates sea grasses,.. as quite important too,.. Maybe particularly up north were we do not have typical coral reefs?
Enjoy the article,..
Climate change and all that nasty CO2 and "acidification" itself is apparently not the maker of trouble for this valuable ecosystem. As with coral reefs: see below from the same source. Thanks, BB , glad you found the real culprit.
"When the corals were exposed to climate change and ocean acidification, like in previous research, the researchers saw that they remained extraordinarily resilient. However, when nitrate and phosphate were added, the coral thermal resilience was compromised while algal growth benefited from excess CO2 and nutrients. Algal dominance over corals in the reef means losing all of the beauty and biodiversity of the coral reefs."
"We added concentrations of nutrients that are ecologically relevant and we noticed that the physiological performance of the corals was compromised. Their resistance to thermal stress was much lower. Their ability to withstand global factors was lower. And we found that the entire microbial community on the coral surface changed," said Dr. Emily Hall, the lead author of the study from the Mote Marine Laboratory
Yu Get it ?
However, realizing the "true" potential of seagrass meadows requires international cooperation, he said. The research is published in Frontiers in Marine Science.
Seagrass meadows are able to store large amounts of carbon but historically they have been virtually ignored in global carbon budgets.
And apparently, they are not adversely affected by CO2 or changes to the alkalinity. They are a CO2 munching machine. So if people would stop flushing the oceans with real pollutants, we should be fine and dandy... Go figure ...
PSA: Very cool link. I've followed this guy, because, um... scientists have groupies too (ha ha ha) for a while. And this message is important for anyone interested in fitness. Not that you would need it to improve fitness, but as a "mythbuster"... Ultimately it's important from a training perspective if one was to go that far...
Lactate is not bad. Doesnt create soreness and is actually a fuel. That's the very cliff note version of things... but it's a cool read: https://phys.org/news/2018-05-lactate-poison.amp?__twitter_impression=true
I actually emailed some work from the same guy to a Boston based "Sports Medicine Physician" who actually says on his radio commercial during a faux interview with a former patriots tight end that lactic acid causes muscle soreness... Apparently his skipped biochem, and human physiology in med school... (sorry, pet peeve)... I never heard back :) ha ha ha!
Interesting discovery and it does seem to be a reasonable explanation. So now we must accept that the former experts were quite wrong. "What looks to be" is not always what it is.
However, this analogy by Brooks is inaccurate. "After injury, adrenaline will activate the sympathetic nervous system and that will give rise to lactate production," Brooks said. "It is like gassing up the car before a race."
It is more " like adding a maintenance repair or fuel boost, during a race. "
The catch, Pi... Is that this knowledge is not new. While Brook's has elevated it... This has been COMMON KNOWLEDGE to physiologists of any focus (relative to humans) since the mid to late 70's at least. The mythology has lasted. Sort of like "you can shoot under the spine and miss the lungs". A myth that seems destined to last, despite the idea being entirely wrong.
That's what kills me on this one... You have some professionals or athletes suggesting lactate creates muscle soreness etc... and it perpetuates the myth.

The article could be boiled down for the common consumer. Maybe, make a poster with cartoon characters ... Good read.
