@codycessna5038: Think about the intelligence here. The otter can understand the abstract concept of pantomime. It’s communication depends on its ability to mentally represent itself as the human and to imagine it’s head being pet from the human perspective. That’s incredible.
I love these examples of cross-species communication.
This photographer built a waterhole about 3 miles from the nearest water source in a very dry part of Kenya’s Southern Rift Valley. He then designed a hide from which to take photos.
We Built a Waterhole, Will Burrard-Lucas Photography Blog, 24 October 2022
You wouldn’t think that so much wildlife could exist in such a dry and seemingly inhospitable place.
I like his night shots:
Of course, my dream was for the lions to turn up and eventually they did. Thinking back to that experience still gets my pulse racing… I was alone with nothing but air between me and the lions. The cats were just a few meters away and seemed impossibly large from my vantage point. The lions knew I was there and held my gaze as they approached the water. Nothing compares to that connection, the feeling of vulnerability and the exhilaration.
The one below was from another nearby water source away from his built one. It was this set of photos that inspired him to build his own hole.
I guess owls are more afraid of humans than of zebra.
These are just a few of his photos. You can visit Will Burrard-Lucas’ site for more and to read about how he constructed his waterhole and hide. What a great idea!
Exercise As A Treatment For Depression: A Meta-Analysis Adjusting For Publication Bias, Journal of Psychiatric Research, June 2016
From the abstract:
The effects of exercise on depression have been a source of contentious debate.
I did not know that. I thought the evidence for benefits of exercise vis-a-vis depression was relatively strong. Although, if I was a big pharmaceutical company for which antidepressants brought in a fair share of revenue, I’d make sure there were studies published that countered benefits.
We included randomized controlled trials (RCTs) of exercise interventions in people with depression (including those with a diagnosis of major depressive disorder (MDD) or ratings on depressive symptoms), comparing exercise versus control conditions. … Twenty-five RCTs were included.
Overall, exercise had a large and significant effect on depression.
Previous meta-analyses may have underestimated the benefits of exercise due to publication bias.
Our data strongly support the claim that exercise is an evidence-based treatment for depression.
Publication bias. I wonder how that happened. You know who benefits from publication bias here? BigPharma.

The Mouse In The Maze experiment:
Some years ago, psychologists used a maze puzzle in an intriguing experiment with college students.* A cartoon mouse was shown trapped inside a picture of a maze, and the task was to help the mouse find the way out. There were two different versions of the task. One was positive, approach-oriented; the other was negative or avoidance-oriented. In the positive condition, there was a piece of Swiss cheese lying outside the maze, in front of a mouse hole. In the negative condition, the maze was exactly the same, but instead of the Swiss cheese feast at the finish, an owl hovered above the maze, ready to swoop down and capture the mouse in its talons at any moment.
The maze takes less than two minutes to complete, and all the students who took part in the experiment solved their maze. But the contrast in the aftereffects of working on different versions of the maze was striking. When the participants later took a test of creativity, those who had helped their mouse avoid the owl turned in scores that were fifty percent lower than the scores of students who had helped their mouse find the cheese. The state of mind elicited by attending to the owl had resulted in a lingering sense of caution, avoidance, and vigilance for things going wrong. This mind-state in turn weakened creativity, closed down options, and reduced the students’ flexibility in responding to the next task.
This experiment tells us something very important: the same action (even something as slight as solving a simple maze puzzle) has different consequences depending on whether it is done to move toward something we welcome (activating the brain’s approach system) or to avoid something negative (activating the brain’s avoidance system). In the maze experiment, aversion was triggered by something as minor as the sight of a cartoon owl. It led to reductions in exploratory, creative behaviors. This is dramatic evidence that the avoidance system can narrow the focus of our lives, even when triggered by a purely symbolic threat.

This was just a puzzle. It wasn’t even real. Yet it had real-life effects on the students.

The five-month-old bar-tailed godwit smashed the record for long-distance migration following a non-stop, 11-day flight from Alaska to Tasmania.
Birdlife Tasmania convenor Eric Woehler said the bird probably lost “half or more of its body weight” during “continuous day and night flight”.
“If a godwit lands on water, it’s dead. It doesn’t have the webbing in its feet, it has no way of getting off the water.”
“So if it falls into the water from exhaustion, if bad weather forces it onto the ocean surface, that’s it.”
11 days. No rest. No food. Flying, flying flying. Tell me birds don’t have it all over humans.

I enjoyed listening to this doctor, Andrew Mester MD, describe Ramsay Hunt syndrome, similar to Bell’s Palsy but usually accompanied by rashes. Ramsay Hunt syndrome and Bell’s Palsy are one-sided facial paralysis involving the 7th cranial nerve or facial nerve. The facial nerve has a cervical branch which reaches down into the neck area. Both syndromes are caused by reactivation of a virus, varicella zoster virus (VZV) for Ramsay Hunt (that’s the virus that causes chicken pox) and herpes simplex virus (HSV) for Bell’s Palsy. The two conditions may present as indistinguishable.*

What causes reactivation of chicken pox virus?
VZV reactivation frequently arises under immune-exhaustion, such as aging, or immunocompromised conditions caused by immunosuppressive drugs, HIV infection, or malignancies.

Could the COVID-19 vaccine suppress the immune response? Yes, if this paper is anything to go by:
