What is another way atoms can become more stable?
Rather than fully gaining or losing electrons, another way atoms can become more stable is by sharing them, thus forming covalent bonds, another intra-bond type.
They are more common than ionic bonds in the molecules of living organisms. E.g., they are key to the structure of carbon-based organic molecules like our DNA and proteins. Covalent bonds are also found in smaller inorganic molecules, such as H2O, CO2 and O2.
One, two, or three pairs of electrons may be shared between atoms, resulting in single, double, or triple bonds, respectively. The more electrons that are shared between two atoms, the stronger their bond will be.
Two basic types of covalent bonds are:
▫️ Polar bonds in which the electrons are unequally shared by the atoms.
▪️ Nonpolar bonds that form between atoms of the same element, or between atoms of different elements that share electrons more or less equally.

What happens if atoms are gaining or losing electrons?
Some atoms become more stable by gaining or losing electrons.
When they do so, atoms form ions, or charged particles.
Ions come in 2️⃣ types:
➕Cations are positive ions formed by losing electrons. E.g., if a sodium atom loses an electron, it becomes a sodium cation, Na+.
➖Anions are negative ions formed by electron gain and named using the ending “-ide”: for example, the anion of chlorine (Cl-) is called chloride.
⚛️➡️⚛️The process itself is called electron transfer.
ℹ️The word ion comes from the Greek word ion or ienai, meaning “to go.” English scientist Michael Faraday coined the term in 1834.
ℹ️Certain ions are referred to in physiology as electrolytes (including sodium, potassium, and calcium). These ions are necessary for nerve impulse conduction, muscle contractions and water balance. Many sports drinks and dietary supplements provide these ions to replace those lost from the body via sweating during exercise.

How many animals have ever existed on Earth?
📌Life appeared on Earth by 3.7 billion years ago. But those first organisms were very simple cells; it would be another 1.4 billion years before multicellular life showed up. Animals probably evolved even more recently, around 800 million years ago.
📌According to scientists, the total number of eukaryotic species on Earth was around 8.7 million, about 7.7 million of which were animals (roughly half were insects).
📌Researchers assume that 99.9% of species that have ever lived on Earth are extinct. So, 7.7 million could be multiplied by nearly 100 percent which puts the total number of animal species at roughly 770 million species.
📌Today, there are around 130 billion mammals, up to 428 billion birds, 3.5 trillion fish and an estimated 10 quintillion insects.
If we extrapolate out these figures using the proportions of the 7.7 million existing species, roughly, there have been approximately 4.5 x 10^27 animals ever on Earth.

What science studies the nervous system?
Neuroscience, also known as Neural Science, is the study of how the nervous system develops, its structure, and what it does.
Neuroscientists focus on the brain and its impact on behavior and cognitive functions and study what happens to the nervous system when people have neurological, psychiatric and neurodevelopmental disorders.
Neuroscience is also often referred to in the plural, as neurosciences.
Neuroscience has traditionally been classed as a subdivision of biology, but today it’s an interdisciplinary science, which liaises closely with other disciplines, such as mathematics, linguistics, engineering, computer science, chemistry, philosophy, psychology, and medicine.
Some researchers say that neuroscience means the same as neurobiology. However, neurobiology looks at the biology of the nervous system, while neuroscience refers to anything to do with the nervous system.

What are some amazing facts about the animals’ nervous system?
ℹ️Sponges are the only multicellular animals without a nervous system.
🪱🐘The size of the nervous system ranges from a few hundred cells in the simplest worms, to around 300 billion cells in elephants ⬆️.
🔰 The minuscule C. elegans nematode worm has just 302 neurons, but it’s able to carry out the same functions as the nervous systems of higher organisms.
🔰 The tiny Megaphragma mymaripenne wasp ⬆️ only lives for 5️⃣ days and has just 7️⃣4️⃣0️⃣0️⃣ neurons. As it changes from a larva into an adult, it destroys the majority or its neural nuclei until just a few hundred are left, because there’s not enough room in its head.
🔰 At a larval stage, sea squirts have the same anatomical characteristics as most vertebrates, but as they grow, they lose their minds – literally. They digest their own cerebral ganglia, which controls movement, because once they’re sedentary, they no longer need it.

What are glial cells?
✔️The second main type in the nervous system are glial cells.
Glial cells (named from the Greek word for "glue") are non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system.
Among the most important functions of glial cells are:
📍to support neurons and hold them in place
📍to supply nutrients to neurons
📍to insulate neurons electrically
📍to destroy pathogens and remove dead neurons
📍to provide guidance cues directing the axons of neurons to their targets.
✍️A very important set of glial cell generate layers of a fatty substance called myelin that wrap around axons and provide electrical insulation that allows them to transmit signals much more rapidly and efficiently.
✍️🧠In the human brain, it is currently estimated that the total number of glia roughly equals the number of neurons, although the proportions vary in different brain areas.

What is the “command centre” of most animals?
📌The nervous system (NS) is the “command centre” of an animal's body that coordinates its behavior and transmits signals between different body areas.
📌The function of the NS is to control movement of the organism and to affect the environment (e.g. through pheromones) by sending signals from one cell to others, or from one part of the body to others.
📌At the cellular level, the NS is defined by the presence of neurons, also known as "nerve cells".
📌Nervous systems are found in almost all multicellular animals, but vary greatly in complexity.
📌The NS derives its name from nerves, which are cylindrical bundles of fibers that emanate from the brain and central cord, and branch repeatedly to innervate every part of the body. Nerves are large enough to have been recognized by the ancient Egyptians, Greeks, and Romans, but their internal structure was not understood until it became possible to examine them using a microscope.

How do CO2 emissions in North and South America look like from space?
Advanced computer modeling techniques allow to make visualizations showing the CO2 being added to Earth's atmosphere over the course of the year 2021, split into four major contributors: fossil fuels in orange, burning biomass in red, land ecosystems in green, and the ocean in blue. The dots on the surface also show how atmospheric CO2 is also being absorbed by land ecosystems in green and the ocean in blue.
🌎In this view ⬆️ highlighting North and South America, during the growing season plants absorb CO2 through photosynthesis, but release much of this carbon through respiration during winter months. One can see fossil fuel emissions from the northeastern urban corridor in the United States. The fast oscillation over the Amazon rainforest shows the impact of plants absorbing carbon while the sun is shining and then releasing it during nighttime hours.

What is the link between climate crisis and meat/dairy products?
The link between climate crisis and meat/dairy products may not be obvious, but for many experts it’s clear.
🥩🥛↔️🌏🌦
Studies affirm that between 11.1 and 19.6% of global human-made greenhouse gas (GHG) emissions come from meat and dairy production/animal agriculture, which is a leading cause of deforestation, responsible for significant biodiversity loss and pollution, and emits large amounts of methane, which alone is the cause of over 25% of global warming.
📌Some experts even claim that animal agriculture is the largest contributor to global climate change.
📌However, according researchers, the extent to which it contributes to global emissions depends on how studies define different economic sectors, and whether they incorporate farming equipment and food exports in the assessment of animal impact.
ℹ️Most sources list animal agriculture as the No. 2 contributor to GHG emissions after fossil fuels.

How humans contribute to climate change?
🇺🇳According to the UN, today burning of fossil fuels by humans is the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.
CO2 is the primary greenhouse gas emitted through human activities.
Human activities are altering the carbon cycle–both by adding more CO2 to the atmosphere and by influencing the ability of natural sinks (forests, soils...) to remove and store CO2 from the atmosphere.
While CO2 emissions come from a variety of natural sources, human-related emissions are responsible for the increase that has occurred in the atmosphere since the industrial revolution that began around 1750.
💡🏭✈️🚇🚘The main human activity that emits CO2 is the combustion of fossil fuels for energy, transportation and industry.
ℹ️According to researchers, CO2 levels are now higher than at anytime in the past 3.6 million years.

What is the difference between global warming and climate change?
🌏🌡📈Global warming is the long-term warming of the planet’s overall temperature. Though this warming trend has been going on for a long time, its pace has significantly increased in the last hundred years due to human activities. As the human population has increased, so has the volume of fossil fuels burned. Fossil fuels include coal, oil, and natural gas, and burning them accelerates what is known as the “greenhouse effect” in Earth’s atmosphere. Scientists continue to study global warming and its impact on Earth.
🌦🌪🌊Global warming has presented another issue called climate change. Sometimes these terms are used interchangeably, however, they are different. Climate change refers to changes in weather patterns and growing seasons around the world. It also refers to sea level rise caused by the expansion of warmer seas and melting ice sheets and glaciers.
Global warming causes climate change.

What is the chemical backbone of life on Earth?
⚫️Carbon is the chemical backbone of life on Earth, required to form complex molecules like proteins and DNA.
⚪️This element is also found in our atmosphere in the form of carbon dioxide (CO2).
🟢Carbon compounds regulate the Earth’s temperature, make up the food for living organisms, and provide energy that fuels human’s economy.
🪨🌊💨Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
🌀The carbon cycle is nature's way of recycling carbon atoms.
⚫️Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
🌊💨In the case of the ocean, carbon is continually exchanged between the ocean’s surface waters and the atmosphere, or is stored for long periods of time in the ocean depths.

What is the Six Degrees of Separation?
ℹ️ The Six Degrees of Separation is the idea that all people are connected with each other by at most six social connections.
✔️ It was originally set out by Hungarian writer Frigyes Karinthy (1887-1938) in 1929. Theories based on the idea were already discussed before him, but it was Karinthy who published a story called the “Chain-Links”. In this story, he particularly tells that the modern world was ‘shrinking’ due to this ever-increasing connectedness of human beings and that any two individuals in the world could be connected through at most five acquaintances.
✔️ Today, this concept is also known as “The Six Handshakes Rule/Theory”. It was put forward in 1969 by two American psychologists: Stanley Milgram and Geoffrey Travers. They conducted a “Small-world experiment” in 2 cities with 300 envelopes that participants handed only over to acquaintances. The conclusion was that each envelope went through six hands.

Can machines think?
❓🤖💭That was the question Alan Turing ⬆️posed at the top of his landmark 1950 paper, “Computing Machinery and Intelligence.” It was a time when rudimentary electronic computers were just starting to emerge.
Turing realized that his test was not designed to determine whether a computer can “think.” After all, it might be fundamentally impossible to know what’s happening in the “mind” of a computer, and even if computers do think, the process might be fundamentally different from the human brain.
❓↔️❓That’s why Turing replaced his original question with one we can answer: “Are there imaginable computers which would do well in the imitation game?” This question established a measurable standard for assessing the sophistication of computers over the past seven decades.
🆒According to modern scientists, the new question was also a clever way of sidestepping the philosophical questions associated with defining words like “intelligence” and “think”.

If a machine can learn, can it dream?
A visual artist Refik Anadol tried to answer this question, using AI, together with the Philadelphia Orchestra.
A 12/meter (40-foot) tall digital screen with 8.2 million pixels, each controlled by AI, was installed on the stage.
As the orchestra played Beethoven’s “Missa Solemnis,” the screen came alive with swirls and cascades of color.
The system used fluid dynamics algorithms to generate animation effects resembling flowing water and wind through hair. For this performance, Anadol “taught” his system by feeding it thousands of images of Renaissance art and architecture, the kind of aesthetics that Beethoven himself would have been consuming when he wrote his celebrated works.
The developer didn’t give his artificial intelligence machine an anthropomorphic name, but refered to it as a “thinking paintbrush.”
The performance that used AI technologies was nevertheless negatively received by many musical critics.

How ionic bonds are formed?
Ionic bonds are bonds formed between ions with opposite charges. It’s an intra-bond type.
🫙 For instance, positively charged sodium ions and negatively charged chloride ions attract each other to make sodium chloride, or table salt. Like many ionic compounds, it doesn't consist of just one sodium and one chloride ion; instead, it contains many ions arranged in a crystal lattice (repeating, predictable 3D pattern) ⬆️.
Within sodium chloride all of the attractions between the ions are strong. A lot of energy is required to pull these ions apart. This trait means sodium chloride has a high melting point and a high boiling point. Those charges also mean that when salt is dissolved in water or melted, it becomes a good conductor of electricity.
ℹ️ Just a few grams of salt could contain more than a septillion ions. It’s a quadrillion times a billion (or 1,000,000,000,000,000,000,000,000).

What is holding our universe together?
⚛️Our universe is made up of atoms, which in most cases are not just floating around individually, but usually interacting with other atoms (or groups of atoms).
Atoms might be connected by strong chemical bonds and organized into molecules or crystals. Or they might form temporary, weak chemical bonds with other atoms that they bump into or brush up against.
❗️Both the strong bonds that hold molecules together and the weaker bonds that create temporary connections are essential as they are literally holding our universe together.
Chemical bonds are formed because atoms are trying to reach the most stable (lowest-energy) state that they can.
Chemical bonds broadly fall into 2️⃣ categories:
🔄 intra-bonds that hold one building block to another inside a compound
➡️⬅️ inter-bonds that attract one compound to another
Intra- and inter-bonding are further divided into different types, but electrons control all types of bonds.

What are the major branches of modern neuroscience?
According to researchers, the following branches of neuroscience, based on research areas and subjects of study can be broadly categorized in the following disciplines (neuroscientists usually cover several branches at the same time):
✔️ Affective neuroscience – in most cases, research is carried out on laboratory animals and looks at how neurons behave in relation to emotions.
✔️ Behavioral neuroscience – the study of the biological bases of behavior. Looking at how the brain affects behavior.
✔️ Cellular neuroscience – the study of neurons, including their form and physiological properties at cellular level.
✔️ Clinical neuroscience – looks at the disorders of the nervous system, while psychiatry, for example, looks at the disorders of the mind.
✔️ Cognitive neuroscience – the study of higher cognitive functions that exist in humans, and their underlying neural bases. Cognitive neuroscience draws from linguistics, neuroscience, psychology and cognitive science. Cognitive neuroscientists can take two broad directions; behavioral/experimental or computational/modeling, the aim being to understand the nature of cognition from a neural point of view.
✔️ Computational neuroscience – attempting to understand how brains compute, using computers to simulate and model brain functions, and applying techniques from mathematics, physics and other computational fields to study brain function.
✔️ Cultural neuroscience – looks at how beliefs, practices and cultural values are shaped by and shape the brain, minds and genes over different periods.
✔️ Developmental neuroscience – looks at how the nervous system develops on a cellular basis; what underlying mechanisms exist in neural development.
✔️ Molecular neuroscience – the study of the role of individual molecules in the nervous system.
✔️ Neuroengineering – using engineering techniques to better understand, replace, repair, or improve neural systems.
✔️ Neuroimaging – a branch of medical imaging that concentrates on the brain. Neuroimaging is used to diagnose disease and assess the health of the brain. It can also be useful in the study of the brain, how it works, and how different activities affect the brain.
✔️ Neuroinformatics – integrates data across all areas of neuroscience, to help understand the brain and treat diseases. Neuroinformatics involves acquiring data, sharing, publishing and storing information, analysis, modeling, and simulation.
✔️ Neurolinguistics – studying what neural mechanisms in the brain control the acquisition, comprehension and utterance of language.
✔️ Neurophysiology– looks at the relationship of the brain and its functions, and the sum of the body’s parts and how they interrelate. The study of how the nervous system functions, typically using physiological techniques, such as stimulation with electrodes, light-sensitive channels, or ion- or voltage-sensitive dyes.
✔️ Paleoneurology – the study of the brain using fossils.
✔️ Social neuroscience – this is an interdisciplinary field dedicated to understanding how biological systems implement social processes and behavior. Social neuroscience gathers biological concepts and methods to inform and refine theories of social behavior. It uses social and behavioral concepts and data to refine neural organization and function theories.
✔️ Systems neuroscience – follows the pathways of data flow within the CNS and tries to define the kinds of processing going on there. It uses that information to explain behavioral functions.

What are some interesting features of the human nervous system?
🔴 The human nervous system can transmit signals at speeds of 100 meters per second.
🔴 The slowest signal transmission occurs inside the skin.
🔴 Every square cm of human skin contains around 200 pain receptors but only 15 receptors for pressure, 6 for cold and 1 for warmth.
🔴 In the human PNS, nerve cells can be threadlike—their width is microscopic, but their length can be measured in meters.
🔴 There are over millions of nerve cells in human CNS, 100 billion neurons in the human brain and around 13,500,000 neurons in the spinal cord.
🔴 Sciatic nerve is the longest and broadest single nerve in the human body.
🔴An optic (cranial) nerve is the fundamental part of the CNS, and the human eye's most significant sensory nerve.

What are the components of the nervous system?
✍️The nervous system of vertebrates has two components: the central nervous system (CNS) and the peripheral nervous system (PNS).
☑️The CNS is the largest part, and includes the brain and the spinal cord.
☑️Structures that do not lie within the CNS, are called the PNS.
The majority of nerves belong to the PNS, even when the cell bodies of the neurons to which they belong reside within the brain or spinal cord.
The PNS is divided into:
🔘the somatic part consisting of the nerves that innervate the skin, joints, and muscles.
🔘the visceral part, or the autonomic nervous system, that contains neurons that innervate the internal organs, blood vessels, and glands, and itself has two parts:
▪️the sympathetic nervous system
and
▪️the parasympathetic nervous system.
ℹ️Some authors also include sensory neurons whose cell bodies lie in the periphery (for senses such as hearing) as part of the PNS; others, however, omit them.

What do we know about neurons?
✔️One of the two main types of cells in the nervous system are neurons.
🔬✍️They can be distinguished from other cells in a number of ways, but their most fundamental property is that they communicate with other cells via synapses, which are junctions containing molecular machinery allowing rapid transmission of electrical or chemical signals.
🔬✍️Many types of neuron possess an axon, a protoplasmic protrusion that can extend to distant parts of the body and make thousands of synaptic contacts.
✍️Even in the nervous system of a single species, hundreds of different types of neurons exist, with various morphologies and functions. For example, sensory neurons transmute physical stimuli such as light and sound into neural signals, and motor neurons transmute neural signals into activation of muscles or glands. In many species, though, the majority of neurons receive all of their input from other neurons and send their output to other neurons.

How global human-related CO2 emissions are calculated?
📊Global human-related CO2 emissions are calculated in GtCO2 (one billion tonnes of CO2) per year.
➕✖️🟰Countries report their emissions through what is known as a ‘bottom up’ approach, where national emissions are estimated by combining data on types of activity with the emissions typically produced by those activities. So, if you know how much CO2 steelmaking produces, and you know how much steel is produced in a country, you can estimate the total quantity of emissions from the steel sector. There are internationally agreed guidelines that specify how this kind of accountancy should be done.
ℹ️According to researchers, in 2022, global CO2 emissions from fossil fuel combustion and cement production reached 36.1 ± 0.7 GtCO2. In the sectoral breakdown of 2022 CO2 emissions power accounted for 39.3%, industry 28.9%, ground transportation 17.9%, residential 9.9%, international bunkers 3.1%, and domestic aviation 0.9%.

What are possible future effects of global warming and climate change?
❗️According to researchers, since 1906, the global average surface temperature has increased by more than 0.9 °C (1.6 °F) - even more in sensitive polar regions.
Effects that could take place later, if warming continues, include:
🌊🆙Sea levels could rise between 26 and 82 cm (10 and 32 inches) or higher by 2100.
🌪🌀🌨☀️Storms, floods and droughts could become stronger and more common.
💧🆘Less freshwater could be available, since glaciers store about three-quarters of the world's freshwater.
🦠Some diseases could spread, such as mosquito-borne malaria.
🌏Ecosystems could continue to change: some species could move farther north or become more successful; others could not be able to adapt and become extinct.
☹️More health, social and economic risks for humans.
ℹ️Scientists claim that atmospheric levels of CO2 are now similar to where they were during the mid-Pliocene epoch, about 3-4 million years ago.

What is the greenhouse effect and why is it important?
✅ The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
✅ Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere. Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, Earth's surface would be some 33°C (59°F) cooler.
✅ Greenhouse gases occur naturally and are part of our atmosphere's makeup. For that reason, Earth is sometimes called the “Goldilocks” planet – its conditions are not too hot and not too cold, but just right to allow life (including humans) to flourish. Part of what makes Earth so amenable is its natural greenhouse effect, which keeps the planet at a friendly 15 °C (59 °F) on average.

How to explain the Six Handshakes Rule?
❇️This rule has a formula that establishes that each person in the world may know 100 people in average.
❇️If each one of your 100 acquaintances is connected somehow to another 100 people, then, the number would increase to 10,000 in the second link in the chain.
❇️In the third link you could increase the number of people you could possibly meet to 1,000,000 and 100,000,000 in the fourth link.
❇️In the fifth one, you would reach 10,000,000,000 people and 1,000,000,000,000 people in the sixth level.
✅⬆️This amount far exceeds the total population of the planet, so the relationships that the members of the chain have in common could be compensated without problems.
ℹ️This formula considers that, of your 100 personal connections, none might have a mutual connection with the 10,000. It is not the case in the real world, but it’s quite likely for your acquaintances to be connected to more than 100 people. So, this would balance it all.

Can AI really pass the Turing test?
One of John McCarthy’s objectives was that a computer would pass the Turing test.
❎❓ According to most computer scientists and AI researchers, to date, no computer has decidedly passed the Turing test. Nevertheless, there have been some convincing contenders.
ℹ️ In 2018, Google unveiled an informal Turing test when he published a video of the company’s virtual assistant, called Duplex, calling a hair salon and successfully booking an appointment. The woman who answered the phone seemed to have no idea she was talking to a computer.
✅ So, it looks like today’s AI algorithms can pass the Turing test in some way.
❗️ However, for many modern researchers, the question of whether or not a computer can pass this test has become irrelevant. Instead of focusing on how to convince someone to talk to a human, rather than the computer program, they think that our real focus should be on how to make human-computer interaction as smooth as possible.

What is the Touring test?
In an essay “Computing Machinery and Intelligence”, published in 1950, the English mathematician and computer pioneer Alan Turing proposed the Turing test.
The test is performed by placing a human in one room and a machine in another. Then a judge, or panel of judges, addresses each room with questions regarding any topic to which a human should be able to respond.
Originally called the Imitation game, this test examines whether humans can tell if they are talking to a machine or a human and has become one of the most important milestones in the research and development of artificial intelligence.
ℹ️ Alongside John McCarthy, Alan Turing (1912-1954) is also seen as a founder of AI and often called the "father of computer science". His Touring machine provided the concepts of algorithm and computation that led to general-purpose computers. Named after him, the Touring Award is the highest distinction in computer science.

What are differences between AI, machine learning and deep learning?
📌 AI, machine learning and deep learning are common terms in enterprise IT and sometimes used interchangeably, but there are distinctions.
📌 Both deep learning and machine learning are sub-fields of artificial intelligence, and deep learning is actually a sub-field of machine learning.
📌 Machine learning enables software applications to become more accurate at predicting outcomes without being explicitly programmed to do so. Machine learning algorithms use historical data as input to predict new output values. This approach became vastly more effective with the rise of large data sets to train on.
📌 Deep learning is based on our understanding of how the brain is structured. Unlike machine learning, it doesn't require human intervention to process data. Deep learning's use of artificial neural networks structure is the underpinning of recent advances in AI, including self-driving cars and ChatGPT.
