One example of how sleep can help regulate emotion occurs in the amygdala. This part of the brain, located in the temporal lobe, is in charge of the fear response. It’s what controls your reaction when you face a perceived threat, like a stressful situation.
When you get enough sleep, the amygdala can respond in a more adaptive way. But if you’re sleep-deprived, the amygdala is more likely to overreact.
Research shows that sleep and mental health are intertwined. On the one hand, sleep disturbances can contribute to the onset and progression of mental health issues, but on the other hand, mental health issues can also contribute to sleep disturbances.
Déjà vu is a sense of having already seen something you're currently seeing or experiencing—coupled with knowing you haven’t actually seen it, which is why it catches many people so off guard. It is thought to be the equivalent of a small brain “glitch,” with two streams of thought colliding. The phrase literally translated from French to mean “already seen.”
It is an incredibly common experience; something upwards of 97% of people are thought to have experienced déjà vu at least once, with more than two-thirds of people experiencing it with some regularity.
St. Augustine, an ancient philosopher, first referred to the concept of déjà vu in 400 AD as “false memoriae,” but French philosopher Emile Boirac was the first to use the term déjà vu in 1890. The first use of the phrase in the scientific world was from F.L. Arnaud, a neurologist who proposed to use it at a meeting of the Societe Medico-Psychologique.
Early research showed promise for déjà vu to be a sign that helped doctors diagnose epilepsy, but more recent research has shown it may be a matter of perception or memory.
通常「Go」と「Travel」は一緒に使われることがありません。 ... 「旅行に行く」のニュアンスで、どうしてもGoと合わせて言いたい場合は、travelではなくtripが使われます。 Go on a trip あるいは Take/Make a trip が英語での「旅行に行く」の一般的表現になります。

そういう中で、怒涛のように流れてくる「GoToキャンペーン」という文字列を見ているうちに、頭がおかしくなっ ... そもそも日本政府のその奇妙な英語もどきの go to travel という表現自体がおかしいので
Humanity has reached its peak and is now probably in its downfall, according to major new research.
People have long thought of human development as one long process of improvement, going on forever. But we are now running up against the limits of how good we can be, say scientists – and most likely we'll now just begin to fall again.
人類はピークに達して、現在文明のレベルは後退を始めている。
The major research review looked at 120 years of data and found that there appears to be limits on our characteristics, like when we die, how tall we can be and how strong we are. We are pushing up against those limits now, the research suggests.
What's more, the ways that we are changing our environment – including through global warming – is probably going to pull those limits down and force humanity into a decline, the researchers said.
For a long time, humanity has looked to be improving. Sprinting speeds that once seemed impossible are now commonplace, for instance, and the record for oldest person in the world is often being broken.
But with time, we'll probably see fewer world records being broken, the new research suggests, and little development in how old the oldest people are. More people might reach those peaks of performance, but the peaks will get no higher, the research published in the journal Frontiers in Psychology found.
"These traits no longer increase, despite further continuous nutritional, medical, and scientific progress. This suggests that modern societies have allowed our species to reach its limits. We are the first generation to become aware of this" said Jean-François Toussaint from Paris Descartes University, France.
Some of those limits now appear to be falling. And it is in large part because of changes we are making to our environment, said Professor Toussaint.
"This will be one of the biggest challenges of this century as the added pressure from anthropogenic activities will be responsible for damaging effects on human health and the environment." he said in a statement. "The current declines in human capacities we can see today are a sign that environmental changes, including climate, are already contributing to the increasing constraints we now have to consider.
"Observing decreasing tendencies may provide an early signal that something has changed but not for the better. Human height has decreased in the last decade in some African countries; this suggests some societies are no longer able to provide sufficient nutrition for each of their children and maintain the health of their younger inhabitants."
