Sensors run into trouble, however, the more sensitive they become, due to ambient “noise”.
My car has a very sensitive sensor that needs to be fixed. It will produce a noise if another car is too close to me. Sometimes it will detect cars that are several feet back in my rearview mirror because it's very sensitive.
Interactive technologies only work as well as the sensors that inform them.
Very true!
This is because when physical vibrations encounter a change in material, some energy gets transmitted while some is reflected backward.
This is why the sound of a person's voice can change while going through different materials or mediums.
While the web hardly moves from the breeze and bending plants, the vibrations conducted through the web from a hapless fly reach the orb weaving spider in milliseconds, her eight legs triangulating the trapped fly’s exact position.
The spider web detects prey by using sound vibrations! I always thought a spider caught its prey by sensing the movement of an organism.
Learning how to manipulate light could help develop better computer monitors or advanced camouflage technologies.
My eyes need better computer monitors :). This would be very useful!
This way of manipulating light results in brilliant iridescent colors, which butterflies rely upon for camouflage, thermoregulation, and signaling.
I knew that the color of their wings was used for camouflage and signaling purposes. I never knew that it was used for thermoregulation. Is this why certain species/colors of butterflies are more common in different climates?
Rather than absorb and reflect certain light wavelengths as pigments and dyes do, these multi scale structures cause light that hits the surface of the wing to diffract and interfere.
The butterfly wing bends light rather than absorbing it!
. Scientists have found that a centrifugal force of 10–70 times the force of gravity can remove 70% of the water in far less time than evaporation would take.
Wow!
Tiny mice rotate their heads and shoulders an incredible 27 times per second, while big bears do so only around 4 times per second.
Great example of how size affects agility in nature!
Drying off quickly is important for mammals because water mats their fur, dramatically reducing its insulating value.
Is this why people have goosebumps on their skin after getting out of a hot shower into a colder part of their house?
In cool weather, removing the water and regaining the insulation value of the coat can be literally a matter of life and death.
I've noticed that polar bears frequently shake water off their coats. This is because they need their warm coat to insulate them from the cold climate.
Take your dog to play in the water, and what’s the first thing she’ll do when she gets out? Likely shake her head and shoulders in a semicircular motion, flinging fat water droplets onto everything in the vicinity.
I can relate to this from personal experience!
We’re putting pride and egos aside, and the reward is intelligence only many millions of years of trial and error can provide. We’re learning that primitive can be synonymous with progress.
It's remarkable to consider how these single-celled organisms have shaped the world we live in today. As humans, we sometimes forget that great things can happen on a small-scale.
We’re facing climate damages over $600 trillion
Is this statistic based upon climate change in the United States or several different countries?
We are in the Anthropocene–an epoch defined by humans and the scars that have disfigured and imbalanced Earth.
I've never heard of this term before!
These masters of efficiency spread delight, wonder, shock, and humility across the globe with the same ease they ooze across a petri dish.
The chemical plant that I work at uses microorganisms to break down materials for waste management.
Not only that, they get tripped up about what intelligence even means if something without a brain can do things like calculate risks over rewards, remember dinnertime like clockwork and trace parts of the cosmos we can’t.
What is the basis for intelligence? Do unicellular organisms use common sense or strategy rather than intelligence?
We tidily classify it as a primitive, no-brained, unicellular organism that gives us a glimpse of our past, and yet the most respected thinkers and institutions turn to it for innovations for our future.
Unicellular organisms play an important role as decomposers and oxygen producers for Earth's ecosystem.
Additionally, the camel’s red blood cells are capable of expanding up to 240% of their original volume without rupturing; most animals’ cells can expand only 150%
That's amazing. So, the camel's red blood cells act as an elastic band.
The dromedary camel is incredibly well-adapted to hot, arid climates. The camel can go days without drinking water, surviving extreme dehydration and safely losing 40% of its body weight in water.
How much water is stored in a camel's bloodstream?
Vampire bats often share food with reciprocal non-kin members of their species, evidencing a complex social exchange where altruistic acts extend beyond genetic ties
Blood is not always thicker than water! Even in the animal world!
These findings enhance our understanding of social dynamics and suggest that the inclination to reciprocate generous behavior may have deeper biological and psychological underpinnings than previously understood.
I think these social dynamics stem from the biological concept of mutualism. One organism does a good deed for another organism, and then that favor is returned.
Capuchins could choose between a grape (a high-value item) and spinach (a lower-value item)
How were researchers able to define what a high-value item is versus a low-value item?
and help recover some of the 85% of oyster reefs that have disappeared globally over the past century due to human activity.
Where do these oysters go? What type of human activity leads to the degradation of oyster reefs?
Wilker says that oyster cement is unique because—in addition to a small amount of mostly-protein organic matter—it contains a high quantity of inorganic calcium carbonate.
Calcium carbonate is naturally found in rocks and is commonly found in minerals such as calcite. Calcium carbonate is used in several different industries.
Oysters grab on to one another, stacking themselves like stalagmites that grow from the ocean floor.
What are stalagmites?
If this form of inter-species calculation is correct, then by significantly altering many environments, and now suffering from the loss of resources due to the destruction of those environments, humans are merely paying the appropriate cost for the behaviors that we have adopted,
The man-made pollution has significantly affected our environment. This is one of the reasons why the price of produce has increased over the past couple of decades.
it’s clear that animals have life, can experience liberty or captivity, and do pursue happiness (and avoid displeasure).
This is the reason why I dislike going to the zoo. I believe that animals shouldn't be put into a confined space.
If we simply want to try to force better behavior by writing laws, we can do that. But if we want people to change their behavior and decision making towards other species, they need to understand the rights of other species as an expression of a fuller understanding of the underlying principles behind the concepts of human rights.
Some humans don't respect other humans. This same concept applies to nature. We have to start respecting other organism's ecosystems.
Studies show that this simple step of identifying the current holes in your knowledge naturally sparks more curiosity, and subsequent engagement, in the relevant material.
Very true! I've noticed that when I annotate a research article and write my unanswered questions on paper, it sparks my intrigue.
These participants were then asked to describe how they thought Houdini had hidden Jennie. Whatever their answer, they were told that they were “close but not completely right”,
I think this is an interesting way of using psychology to influence people to research and learn more. When you tell people that they are "close to the answer", they will become more motivated to figure it out.
When the participants were highly curious about a fact, they were 30% more likely to recall it.
That is why it is important to study a subject that you love and are interested in. You will be able to retain information better when you are truly interested in the topic at hand.
various studies have shown that people’s curiosity can predict their academic success, independently of IQ.
This is something that my teachers, mentors, and parents have taught me. The most intelligent person in the room is the individual who asks the most questions.
I’ll tell you what that is before the end of the article, but you might want to avoid the temptation of skipping straight to that section – since a wealth of scientific research shows that allowing your curiosity to be piqued in this way can be incredibly good for your mind.
I agree with this sentiment, as expressed by David Robinson. We live in an era where vast amounts of information and data are readily accessible to us. Instead of allowing ourselves to brainstorm, we take the easy way out by using Google or AI to help us.
