Why is color blue rare in nature
Blue tigers are nonexistent. There are no blue squirrels, bats, or canines. Blue whales are not exactly that blue. Although animals can be found in virtually any color, blue appears to be the rarest. However, what's interesting is that when we do encounter a blue animal, it has an incredible appearance. Blue is not handled halfway by nature. To comprehend the reason for this, we shall embark on an exploration of evolution, chemistry, and some exceptionally fascinating physics. However, to ascertain the reason why creatures exhibit any coloration, we must examine some butterflies... because butterflies are magnificent... And if you disagree, you are mistaken. Bob Robbins appears here. He is the curator of Lepidoptera at the Washington, D.C.-based National Museum of Natural History.

Why is Utah so weird?
Mormons. Answer: Mormons made Utah odd. A century and a half of Mormon voting majority in an isolated, insular state made Utah unique in the nation. The red-rock deserts of Nevada and Arizona, the deep-red politics of Idaho and Wyoming, the glitzy ski towns of Colorado and Wyoming, and the ruggedly independent, outdoors-loving culture of the mountain west region make Utah seem like the intuitive average of its neighbors. But it has certain things its neighbors don't. The area has drive-thru soda businesses.

US vs China Aircraft Carriers.
The US has the most expensive and advanced carrier fleet, and China is investing to catch up. These are crucial to modern warfare and may be crucial in a US-China conflict. Do they justify this cost? They matter why? My name is Sam Fellman. I'm a US Navy veteran and Business Insider defense editor. USS Nimitz was my ship. The US has 11 airlines. The majority are Nimitz-class carriers. One new class exists and two are being constructed. The Gerald R. Ford. The Ford is one of the most expensive ships ever. The cost is $13 billion. That embodies America and the troops like nothing else. The Ford is special because it has untested transformational leap-ahead technologies, which delayed ship deployment. Ford is running.

ADHD in women
Hi Brains. Just so you know, I'm an ADHD woman. Like a man with ADHD, I have mental health issues, but they affect me differently. Intro music Before we begin, I want to note that several guys commented on my ADHD in girls episode, "Wait.. I have the GIRL presentation?" There is no "girl presentation" of ADHD, but research shows that women—at least cisgendered women—present differently to cismen due to biological and social factors, which can make our ADHD harder to diagnose and treat. Because people are diverse, part of this may apply to both genders.

why do we forget?
Amidst the current frenzy of events, one might have observed an anomalous occurrence. Perhaps, each time you enter a room, you find yourself forgetting what you were seeking. Alternatively, you may have forgotten the title of the film that you watched last night. Those who have recently experienced an increase in forgetfulness beyond what is typically observed are most certainly not alone.

What is narcissism?
Ancient Romans and Greeks had a legend long before the invention of the selfie about someone who was a bit too preoccupied with his own appearance. One account describes Narcissus as an attractive individual who traveled the globe in pursuit of a romantic partner. Following his rejection of the deity Echo, he became enamored with a reflection of himself he beheld in a river. Narcissus, unable to extricate himself, submerged in water. The location of his death was commemorated by a flower, which we shall call the Narcissus.

How to spot a liar
"Sorry, my phone died." "It is absolutely nothing. "Everything is fine." "These allegations are completely unfounded." "The company was not aware of any wrongdoing." "I love you." Ten to two hundred lies are uttered daily, and throughout history, inventors have devised a variety of methods to identify them, including 400-pound electroencephalograms, voice-stress analyzers, eye trackers, infrared brain scanners, and polygraphs (as well as voice-pressure and breathing monitors).

Why do we love
Romantic love is beautiful, seductive, tragic, and soul-crushing, often all at once. Why subject ourselves to its emotional toll? Does love enrich our lives or do we use it to avoid loneliness and suffering? Is love a cover for sexual desire or a biological trick to procreate? Is it sufficient? Do we need it? No science or psychology has found the goal of passionate love. Over time, several of our most esteemed philosophers have proposed intriguing views. Love restores wholeness.

Why you should daydream
You devote one-third to one-half of your daily waking hours to reverie. That may appear to be an enormous waste of time, but scientists believe that if it did not serve a purpose, humans would not have evolved to do it to such an extreme degree. So as to determine what is happening, let's examine the bored adolescent, the foremost mind-wanderer, in greater detail. It would be quite fascinating to uncover something, anything. In fact, even this plant.

How to study
Medical residents acquire knowledge of innumerable techniques, interventions, and procedures that they subsequently implement in order to preserve lives. Literally, the ability to recall these skills can mean the difference between life and death. In light of this, a research study conducted in 2006 divided a cohort of surgical residents who were undergoing artery suturing instruction into two distinct groups. While all groups were provided with identical study materials, one group made a minor adjustment to their approach to studying them. One month later, this group demonstrated a marked improvement in surgical performance compared to the remaining residents. Along with that group's success factor, we shall expound upon two additional efficacious study techniques that have practical applications beyond the confines of the classroom. However, in order to comprehend the efficacy of these approaches, it is imperative to initially deconstruct the mechanisms by which the brain acquires and retains information. Consider that you are attempting to commit to memory the anatomy of the heart. Memories of newly introduced concepts are transiently encoded in clusters of neurons located in the hippocampus, a cerebral region. You reactivate these neurons as you sustain your understanding of the heart's mechanisms in the classroom or scrutinize its chambers in preparation for an examination. This repeated discharge stabilizes the memory by fortifying the intercellular connections. The process by which knowledge of heart anatomy is progressively retained over time entails the neocortex, an additional cerebral region. The process by which data is transferred from short-term to long-term storage remains poorly understood; however, it is hypothesized that this occurs between study sessions and, arguably most significantly, while sleeping. In this stage, the recently acquired information is incorporated with other pertinent concepts that you are already familiar with, such as the methodology for quantifying heart rate or the anatomical structure of other bodily organs. Beyond that, the procedure continues. Recalling heart anatomy induces a reactivation of long-term memory, rendering it vulnerable to modification. It is possible to revise, fortify, and reintegrate the knowledge with additional data. Our initial investigation technique is as follows. Self-evaluation through the use of flashcards and exams compels one to actively retrieve information, thereby strengthening and modernizing the memory. Frequently, students favor alternative study techniques, such as rereading textbooks and annotating notes. Conversely, these practices may engender an illusory perception of mastery due to the conspicuous presence of the information. Conversely, self-testing enables one to assess their knowledge with greater precision. However, suppose that you forget the answers while performing this task. Not to worry—in the long run, learning can be enhanced by making errors. There is a theory that as one laboriously searches for the answer, pertinent knowledge is activated. Then, upon subsequent disclosure of the accurate response, the brain will be in a better position to incorporate this data into its preexisting knowledge. Our second method is an extension of the initial. When studying with flashcards, it is optimal to incorporate a variety of subjects into the deck. By interleaving the concepts you practice in a single session, rather than concentrating on a single skill or subject at a time, retention can be improved. One plausible explanation for this phenomenon is that, similar to examinations, cycling through various subjects induces the brain to momentarily forget and subsequently retrieve information, thereby fortifying the memory. One might also discover correlations among the subjects, thereby enhancing comprehension of their distinctions. Following an understanding of when and how to study, our final strategy will now address how. Scheduling your review over several days provides an opportunity for intermissions of rest and sleep. The brain is hard at work "offline," accumulating and integrating information in the neocortex. Therefore, although it may seem logical to cram for an exam the night before, since the material will still be fresh in your consciousness, the information will not be retained for the long term. We return to our medical residents at this point. The time devoted to studying the surgery was identical for both groups. However, the training of one group was compressed into a single day, whereas the training of the other, more successful group was spread out over four weeks. Each of these three effective study techniques is specifically designed to operate on the workings of the human brain. They reinforce and supplement the remarkable mechanism by which the brain processes and stores the copious amounts of information it is exposed to on a daily basis.
