Chernobyl, Ukraine: The Worst Nuclear Disaster Known to Planet Earth

mollysherrill Science November 19, 2025#Chernobyl, #mutations, #nuclear reaction 0 Comment

This is a picture of bumper cars at an abandoned amusement park in Chernobyl.

On April 26th, 1986 a nuclear power planet exploded in Chernobyl, Ukraine after a reactor systems test. The Soviet government lied to the people living in Chernobyl, but eventually they were caught due to radiation abnormalities in other European neighboring countries. People were evacuated but the impacts that the radiation had on the land, animals, and people have stuck.

Over 100 reactants were released into the air when the explosion occurred, most of which died quickly, while others, including iodine, strontium, and caesium, lasted a few weeks, months, and even years. The isotopes Caesium-130 and Strontium-90 are still present in Chernobyl today.

The citizens and the environment were not safe from the dangers the explosion created, and no one is safe even to this day.

Affect on Citizens

There were between 115,000 and 135,000 citizens in Chernobyl at the time of the nuclear disaster. The area was extremely dangerous, and it still is to this day.

When the power plant exploded, the radiation leaked out into the environment. The citizens were unknowingly exposed to the harmful amount of radiation and chemicals until other countries stepped in. The chemicals were increasing diseases that were both mental, emotional, and physical. Chemicals like Iodine were linked to thyroid cancer and strontium could lead to Leukemia for some.

The harmful amounts of chemicals and radiation also affected the citizen’s lives and over all life-span. Some of those who were exposed to the radiation died in the moment. Others died some time after, while the rest are expected to have a shorter life-span.

When the government finally opened up to the public, 115,000 citizens from the most contaminated areas were evacuated. Along with 220,000 people later when scientists and the government learned of how dangerous the radiation was. Though people were evacuated, there were still deaths in the event, caused after, and shortened lives that were impacted by the radiation. Out of the 600 workers working on the power plant, 28 were killed. One of which was killed by the blast, along with another worker who died in the hospital soon after.

Along with that, 6,000 children were diagnosed with thyroid cancer because of the radiation absorbed by the food they were eating. Though ninety-nine percent of these cases were treated, 15 children and adolescents died from thyroid cancer across three different countries.

The effect on the citizens did not just have an impact on their physical state, but it also increased depression, anxiety, and alcoholism in the citizens.

Environmental Change

The chemicals and radiation affected far more than the citizens, it affected the animals, plants, and water in the environment. The soil absorbed chemicals like caesium-130 and strontium-90 because they have physiochemical properties with calcium and potassium. Along with that, the vegetation absorbed some harmful chemicals through the soil and the plants’ roots.

The animals consumed the contaminated plants, contaminating the animals’ meat, milk, and other edible properties, which made its way to humans. Over time, iodine’s short life died out and the main cause of milk and meat contamination became caesium-137. The chemicals have also impacted forests, urban areas, lakes, and several other places which are struggling to decontaminate. For example, forests are decontaminating at a rate of less than 1% each year.

Animals also suffer mutations, which have been both beneficial and harmful to the animals the Chernobyl is inhabiting the area. One of the beneficial mutations that an animal has undergone in Chernobyl’s harsh environment includes black frogs, who have the same life-span as the average green frog.

Meanwhile, several other mutations have posed threats to animal health, like tumors. This deer grew an extra set of legs due to the harmful chemicals in Chernobyl.

This is a mutated deer found in Chernobyl, Ukraine with five legs.

The Reopening

Chernobyl, Ukraine, is now one of the most horrific places on planet Earth ever since the explosion that had taken place on April 26th, 1986. Animals, plant life, humanity, and other aspects of nature have been changed because of the harmful amount of chemicals that was released years ago.

Many people wonder when Chernobyl will open once again for human habitation and the answer is not quite clear yet. It could be hundreds of years and some even say it will reopen by the time we get to Mars, but for now, it is clear that the dangers of Chernobyl has made its mark on our planet.

Alien Life, Far-Fetched?

mollysherrill Science October 15, 2025aliens, NASA, space 0 Comment

This is a photo of a potential alien aircraft sighting.

Alien Life in our universe may seem far-fetched to some, but in reality, there is plenty of evidence that supports the possibility of extraterrestrial life. NASA scientists have been searching for extraterrestrial life since the 1960, and have found much evidence that can be linked to aliens. While there has been no direct proof, there has been plenty supporting the possibility.

For a long time, people all across the world and ages have wondered if aliens are real and have sent out technology to map our universe and search for alien life. So far we have found signs that life on Mars did exist once, along with signs that some other planets in our galaxy could be home to alien life. Aliens could be out there, living lives as we do everyday.

In 1992, NASA intensified the focus on extraterrestrial life, now searching for life on Mars, Jupiter’s moons, and beyond. Since then, NASA has found lots of evidence of life in the past existing on some of our solar systems planets and dwarf planets. So who is to say that life has not existed on other planets in our galaxy?

For many centuries scientists have proposed that aliens may exist. This can be taken back all the way from around 6th century BCE.

Ever since 1960, NASA has been looking for aliens. Later they enhanced their focus on the possibility in 1992. Their research has shown that some solar systems and planets including the TRAPPIST-1 system, the K2-18b system, and with many others, may have potentially habitable planets.

Each of these systems have caught scientists’ eyes.

TRAPPIST-1

The TRAPPIST-1 system has many planets that are about the size of Earth, and they all orbit a red dwarf star. Three of these planets are found in a potentially habitable zone.

One of the downsides is these planets are tidally locked, meaning they might have permanent day and night sides. This can result in very different climates than the ones seen on Earth.

Along with that, while the dwarf star in the TRAPPIST-1 system is currently active, it is emitting powerful flame bursts. These flame bursts could have destroyed the atmosphere on the planets in that system.

This illustration from NASA shows what the TRAPPIST-1 system may look like, using information about the distance between the red dwarf star, their sizes, and their diameters.

TRAPPIST-1 is definitely worth attention as it has several planets that may be habitable. While scientists are studying the TRAPPIST-1 system, there are other systems also catching their attention.

K2-18b

110 light years away, there is a planet about eight times larger than Earth. This planet is very likely to host alien life. This planet is K2-18b.

K2-18b is inside the habitable zone, and unlike any other planets scientists have studied, it has many habitable traits.

This planet has temperatures that can sustain water, and it has a rocky surface. Along with that, the Hubble telescope has detected water in its atmosphere. It is highly likely that this planet can host life.

This is an illustration of what K2-18 may look like.

Unfortunately, this planet has some more dangerous side notes.

The red dwarf star that K2-18b orbits has a high level of activity, and this can be harmful to life on that planet.

Additionally, the Hubble Telescope detected water vapor in the atmosphere, it also detected Hydrogen and Helium too.

K2-18b certainly has lots of habitable traits that scientists have never seen on one planet. It is possible that it may have life, but with the other studies of its star and its atmosphere, it may not.

Likely or Not

Scientists are on their way to answer this ongoing question: “Does alien life exist?” They are using their tools to find proof they exist or simply just a theory.

For now, we have not found a one-hundred percent guaranteed habitable planet other than Earth, but we have found evidence leading to several potential ones.

Aliens may exist, they may not. One thing is for sure, it is not a guess, but it has high chances of being proven.

So is alien life far-fetched? No, it is a huge possibility but in the end, it mainly depends on what you believe. Well, until scientists finally located them.

Sea Turtles Battle Hypothermia

skeltcal000 Science May 8, 2025Cape Cod, Cold water, Hypothermia, New England, Sea Turtles 0 Comment

In New England the water temperatures are dropping leaving sea turtles in critical condition with hypothermia.

Why are Turtles Getting Hypothermia?

In Cape Cod, New England, hundreds of turtles have been found on beaches suffering from hypothermia. Normally, the water around the Gulf of Maine does not get very warm throughout the year causing the majority of the turtles to be kept out of Cape Cod due to the cold water. But the last couple of years, the water has been getting warmer during the summer months.

This makes it so that the turtles can funnel into Cape Cod for a big chunk of the summer. The problem is, when the water’s temperature drops the turtles are unable to get out. The turtles should be in a lot warmer water and they want to go south, but the shape of Massachusetts acts as a trap and doesn’t allow them to head straight south.

Because they are unable to get out, and the water temperature is dropping 30 degrees colder than what the turtles are used to, the turtles become very cold and float up to the surface where the wind blows them ashore.

Turtles are reptiles to their internal body temperature is the same as the water temperature that is surrounding them. In the last couple of weeks about 300 cold stunned sea turtles have been washed up onto beaches.

What are People Doing About it?

Some of the turtles are being brought to a New England aquarium for rehabilitation. The aquarium claims that it treats hundreds of turtles every year.

Volunteers from Mass Audubon work to rescue the cold-stunned turtles that get washed ashore, then they bring them to the New England rehabilitation aquarium. At the aquarium they very slowly warm up the turtles to the normal temperature that they are supposed to be at. This process can take anywhere from a couple months to two years.

Because the turtles are so cold, the aquarium heats them up very, very, slowly. About ten degrees fahrenheit per day. They do this until the turtles are in about 70 degree water.

The owner of the New England aquarium said, “Changing the temperature too rapidly can be deadly for these turtles”.

Many of the turtles that come to the aquarium have pneumonia so they give the turtles any antibiotics that they might need. Once the turtles are stable, they make sure they are eating, then when they are ready, they are released back into the ocean.

Why Should We Help The Turtles?

Turtles are a very important part of the ocean’s ecosystem. For example, sea turtles are a very important part of our planet’s food web and play an important role in maintaining the health of the world’s oceans.

Sea turtles regulate a variety of other organisms. One way they do this is simply by eating them. By sea turtles eating seagrass, it keeps it from growing so long that it suffocates itself. Healthy seagrass beds then act as a nursery for other marine species. So, sea turtles in a way are helping other important marine species survive by simply eating.

In conclusion, we should do whatever we can to help save turtles from the dangers of hypothermia because if we don’t we could lose a lot of marine species such as sea grass. If you live nearby this area, you could help take turtles to rehabilitation centers. If you don’t live near by you could donate money to any of the facilities that are working to save turtles.

Storm Chasing The High Speed World Record

chareeth000 Science March 11, 2025March 11, 2025Earth, Science, storms 0 Comment

Storm chasing is a great way to learn about our earth around us. While terrifying to be right in the path of a tornado, it’s still the most common storm chasing. So why do we storm chase well, science. Storm chasing can show us the many parts of a storm that we would otherwise not be able to collect. This research can allow us to better understand storms such as tornadoes, we can learn patterns and how they behave, we can also find ways to possibly lower chances of bad tornadoes or even just prevent them.

Different ways of collecting this science can range all around. Basic strategies such as pictures are the beginning you follow a storm and get good close up photos, now obviously that doesn’t mean run next to a tornado but as close as you can safely get. Another way is probes. Some storm chasers use probes to get up close and personal without having the danger of death. Many probes must be placed in the tornado’s path then the tornado lifts the probe and the probe does the rest. The probe takes in science such as wind speed, direction of the wind, humidity, temperature, and barometric pressure or in a simple term it’s just the air pressure.

If you want to become one here’s what you need. A vehicle of some sort but trucks are most popular, a laptop to allow you to do many thing such as take notes on your finds, mobile internet such as a generator and a router in your car but preferably not cellular because the storms can start to make you signal worse and that the last thing you want to happen. Storm chasers make from 32 to 43 USD per hour. Becoming a storm chaser requires a degree in meteorology. And if you don’t feel like doing it as your career of choice you can easily just do it for a hobby many people do.

Some crazy tools in storm chasing can be so simple but yet so useful such as anchoring spikes. They are strong drills that pull your vehicle into the ground holding it in place so you can get closer to the tornado, but you can’t move with them deployed. Another crazy tool is a vehicle and if very famous it’s called the Dominator, it costs 750,000 dollars but has many great things such as its bullet proof armor and it can keep stationary within 100 ft of a tornado most cars would be scrap at that distance and it can withstand 200 mph wind (321 kph). The Dominator 3 has a missile launcher that was modified to shoot probes, it also has many other great aspects to it such as its built in barometer, thermometer, hygrometer,high res anemometer, and dew point sensors. The Dominator 3 is a very popular storm chasing vehicle unfortunately while the Dominator 3 could survive a tornado it apparently couldn’t withstand a deer impact because it stopped being used after a collision with a deer and it got a radiator leak, and brake failure.

How Our Definition of Autism Has Evolved

To Start

Autism’s journey resembles a kaleidoscope—once an indistinct blur, now a vibrant and lucid spectrum, continuously evolving as new patterns of understanding emerge. Autism was once mistaken for schizophrenia, but it is now a celebrated spectrum.

This article covers autism history from 1952 to now, serving as a go-to for those seeking information in the U.S.

It started as schizophrenia but tests and consultations distinguished it as Autism Spectrum Disorder.

Understanding autism’s journey requires looking back at its historical roots.

Historical Perspectives

In 1952, many conflated autism with childhood schizophrenia or cold parenting.

(Read my last article for an explanation of Schizophrenia.)

In 1980, autism was reclassified as pervasive developmental disorder, distinct from schizophrenia and different from today’s understanding.

As perceptions shifted, so did the frameworks for understanding autism.

As the understanding of autism evolved, researchers faced significant challenges in distinguishing it from other conditions like schizophrenia.

Evolution of Understanding

In the early years of autism research, distinguishing autism from other conditions like schizophrenia posed significant challenges.

Many children exhibiting autistic traits were often misdiagnosed with schizophrenia due to shared symptoms such as social withdrawal and communication difficulties.

These misconceptions were further fueled by societal beliefs that attributed such behaviors to cold parenting or emotional disturbances.

The DSM’s Role: Defining Autism Over the Decades

Recognizing the need for clearer diagnostic criteria, authorities implemented the DSM (Diagnostic and Statistical Manual of Mental Disorders) to elucidate autism diagnosis but left much open to interpretation.

Although the initial editions left much open to interpretation, they marked a crucial step toward understanding autism as a distinct condition.

The DSM’s evolving definitions played a pivotal role in shaping diagnosis, gradually moving away from the conflated views of autism and schizophrenia.

It was published in 1952 with limited focus on autism.

Researchers recognized autism as a mental disorder affecting development, not just a product of their early environment.

Recognizing these challenges, the introduction of the DSM marked a critical step forward.

DSM-II

Published in 1968, the DSM-II marked a pivotal moment as the second edition of the Diagnostic and Statistical Manual of Mental Disorders.”

It played a crucial role in establishing standardized criteria for psychiatric diagnoses, offering clinicians a unified framework for evaluation.

This edition notably began to distinguish autism from schizophrenia, setting the stage for a more nuanced understanding of developmental disorders. “I am different, not less.”

DSM-III

Then, the DSM-III came out and listed some criteria.

DSM-III Diagnostic Criteria for Autism:

Lack of Interest in People: Individuals may show little to no interest in interacting with others.
Severe Impairments in Communication: Challenges in verbal and non-verbal communication are prevalent.
Bizarre Reactions to the Environment: Unusual responses to environmental stimuli or changes.
Early Onset of Symptoms: Symptoms typically develop within the first 30 months of life

With evolving definitions, the DSM-III played a crucial role in shaping diagnosis.

Later, DSM-III revised the diagnosis, acknowledging that not all cases were extreme, so they added a new condition to their list which they were calling pervasive developmental disorder-not otherwise specified. This lengthy term described milder cases.

Building on these advancements, the DSM-IV further refined the classification of autism, inching towards a broader spectrum.

DSM-IV

Although it didn’t say spectrum, it began inching towards that definition. So instead of schizophrenia, it started being understood as a spectrum of disorders that all were labeled the same thing.

As expert Jordan Hilkowitz said, “Autism is not a tragedy. Running out of bacon is a tragedy.”

Between 1994 and 2000, experts labeled autism as a spectrum disorder through the DSM-IV, identifying it as five separate disorders:

DSM-IV Classification (1994-2000):

Autism
Pervasive Developmental Disorder-not Otherwise Specified (PDD-NOS)
Asperger’s Syndrome
Childhood Disintegrative Disorder (CDD): More commonly found in girls than boys.
Rett’s Syndrome

In 2003 they found over 100 genes that could play into autism, but none that were directly linked to it, so they decided to say that is more of a spectrum than a straight diagnosis.

“Our goal is to create a world where everyone belongs.”

DSM-V

The DSM-V was soon released also known as the DSM-5, and only then was the idea adopted of a continuous spectrum.

Before its release, many feared a spectrum diagnosis might disrupt their identity and belonging.

They feared it would reduce their pay and services. However, researchers found it helped more people get diagnosed.

As expert Gilles Trehin illustrates, “Autism is not a problem to be solved, but a reality to be experienced with joy.”

These pivotal changes in diagnostic criteria were driven by pioneering figures who reshaped our understanding of autism.

Notable Figures in Autism History

Grunya Sukhareva

In 1925, Grunya Sukhareva pioneered the first clinical descriptions of autistic traits.
In the early 1920s, at a children’s psychiatric hospital in Moscow, Grunya Sukhareva observed boys whose behaviors markedly diverged from their peers.
Grunya Sukhareva portrait.
These children were characterized by profound social withdrawal and an adherence to repetitive routines, yet they possessed remarkably intense interests in specific subjects.
Sukhareva meticulously chronicled these traits, capturing the subtleties and nuances with precision.
Her pioneering insights offered one of the earliest clinical depictions of what would later be recognized as autism traits.
This revolutionary work not only redefined contemporary understanding but also laid a crucial foundation for future explorations in the field.
Her revolutionary work provided early insights into behaviors that defined the autism spectrum, predating Kanner and Asperger.
While Grunya Sukhareva laid the groundwork for early autism research, Hans Asperger’s insights further expanded the understanding of the condition.

Hans Asperger

Hans Asperger once observed that “Not everything that steps out of line, and thus ‘abnormal,’ must necessarily be ‘inferior.’”
This perspective was pioneering, as he saw beyond challenges to the talents within, leading to the recognition of Asperger’s Syndrome.
While working at the University of Vienna, Hans Asperger observed a young boy who struggled socially but excelled in languages and math.
Noticing the boy’s potential, Asperger believed these “autistic psychopathy” traits were not deficits but unique strengths.
An Austrian pediatrician in the 1940s, Asperger’s work laid the foundation for understanding a unique presentation of autism.
His pioneering insights challenged conventional views and continue to shape how educators and clinicians perceive autism today.

Leo Kanner

Leo Kanner, often called the ‘father of child psychiatry,’ made a groundbreaking discovery in 1943.
In 1943 at Johns Hopkins Hospital, Leo Kanner studied 11 children exhibiting traits such as social withdrawal and a desire for sameness.
As a psychiatrist at Johns Hopkins Hospital, Kanner was the first to formally describe autism as a distinct condition.
Kanner’s detailed case studies were revolutionary, identifying autism as a distinct condition separate from schizophrenia. His work laid the foundation for modern autism research and diagnostics, shaping the field for decades to come.

Dr. Catherine Lord

She is the leading specialist in autism research today.
Her research focus is developing methods to identify strengths and difficulties in individuals with ASD.
Quote from the Semel Institute: “Her research and clinical work are aimed at improving methods of identifying strengths and difficulties…and working with families and individuals to maximize independence and well-being.”
Her current priority is developing better ways to measure changes in social behavior and communication over short periods, to monitor progress without bias.

Temple Grandin

Temple Grandin, a renowned animal behavior expert and advocate for autism awareness, has transformed livestock handling practices through her innovative designs.
Her unique perspective as an individual with autism not only revolutionized the industry but also serves as a powerful reminder of the value of neurodiversity.
Grandin revolutionized livestock handling by leveraging her unique perspective, illustrating how autism can lead to groundbreaking innovations.

Greta Thunberg

Greta Thunberg, a trailblazing climate activist, has become a leading voice in the fight against climate change.
She openly shares her experiences with autism, viewing it as a gift that enables her to focus intensely on her mission.
Her straightforward communication style has inspired millions worldwide, demonstrating the powerful impact of embracing neurodiversity.
Thunberg’s story highlights how individuals with autism can drive significant change, reflecting the evolving understanding of autism as a spectrum of diverse talents and perspectives.

Dan Aykroyd

Dan Aykroyd, a comedy icon and actor, has left a lasting mark on film and entertainment.
Candid about his autism, Aykroyd credits his inventive genius to his singular perspective.
His fascination with the paranormal, a special interest shaped by his autism, led to the creation of the beloved ‘Ghostbusters’ franchise.
This iconic film exemplifies how Aykroyd’s neurodiversity fueled his inventive storytelling and humor.
Aykroyd’s journey highlights the powerful role of autism in fostering creativity and innovation, underscoring the importance of embracing diverse perspectives within the arts.

Reflecting on these contributions highlights the profound impact of autism’s evolving story.

The journey of autism, from shadow to spectrum, reflects decades of change, impacting countless lives with newfound understanding and acceptance. As we look at these shifts, it’s clear they offer more than just awareness—they offer hope and belonging.

Kathleen Seidel once said, “Autism is as much a part of humanity as is the capacity to dream.” This quote beautifully captures the essence of autism’s journey, reminding us that embracing neurodiversity enriches our shared human experience.

These stories remind us that autism is not just a diagnosis but a spectrum of diverse talents and perspectives. As Temple Grandin, Greta Thunberg, and Dan Aykroyd show, embracing neurodiversity enriches our world in unexpected ways.

As you reflect on this article, consider your role in fostering a world where everyone belongs. Your actions today can shape the spectrum’s future tomorrow, ensuring that dreams and understanding continue to flourish.

Some of the World’s Most Deadliest Sea Creatures

cliffmck001 Science November 19, 2024#beach, animals, dangerous, sea creatures, sea life 0 Comment

These are some of the deadliest sea creatures in the world. This is about how deadly they are and where they are located on the earth. Some might not seem harmful but they have a powerful venom punch. So be careful the next time you go to the beach.

Box jellyfish

These grocery bag looking fish are cool but also very venomous. Box jellyfish live in warm coastal waters around the world. Their tentacles can reach up to 3m long! It doesn’t seem that long but that is over 9 feet! Their venom can cause people to die of heart failure, and they are one of the most venomous sea creatures. There are between 40 and 100 deaths a year.

Beaked Sea Snake

These slithering sea snakes are found in the Arabian Sea, Persian Gulf, south of the Seychelles, Madagascar, the seas of South Asia and Southeast Asia. These creatures hold a powerful toxin. This toxin can cause paralysis and can lead to respiratory failure. Bites from this snake are rare, because of their non-aggressive attitude to humans. Though they are considered aggressive. Most bites from them are from fishers trying to untangle them from their nets.

Cone snail

Cone snails are small but mighty. They live in shallow water near coral reefs but they also hide in sand. They hunt by sending out a hollow venom filled harpoon. 30 deaths are ever recorded, and none are anti-venom. So be careful when you pick up snail shells at the beach.

Stone Fish

These stone looking fish are practically invisible. They live in the Indo-Pacific Ocean, Red Sea, East Africa, French Polnesia, Ryukyu and Ogasawara islands, Australia. These fish have defensive dorsal spines that can release a powerful venom if they are disturbed. If you get poisoned by this fish it can lead to death. So be careful when you go swimming in the ocean.

Blue-ringed Octopus

They might look beautiful but they have one of the most potent venom in the sea. Blue ringed octopuses live in the Sea of Japan, Waters of southern Australia, The Philippines and Vanuatu. They have salivary glands that produce tetrodotoxin which is another poison. They disperse the venom throughout their body as a defense mechanism. This venom can cause paralysis. Injuries to humans are from being bitten and by accidentally eating it.

Puffer Fish

Puffer fish are found in marine habitats, some can be found in freshwater rivers in Southeast Asia, South America, and Africa. They are neurotoxic when consumed. They are on Japanese menus as “fugu”. Chefs have to be specialty trained to properly prepare puffer fish to serve it in their restaurant. Why these creatures are deadly is because of food poisoning if they are not properly prepared for people to eat. Most of this food poisoning comes from people catching them and preparing it themselves without the proper training.

Stingray

Stingrays are a beautiful fish that live in the Pacific and western Atlantic. Stingrays have venomous barbs on their tail. When they are disturbed they will move their tail. Being attacked by one is a very small chance but they have been known to attack people who have disturbed them.

Saltwater Crocodile

Saltwater crocodiles live in India’s east coast, Southeast Asia and the Sudaic region to northern Australia and Micronesia. They have the strongest bite in the animal world. They are aggressive when they are defending their territory. There have been 47 attacks on humans in Queensland Australia, between 1985 and July 2023. 13 of these have ended in a fatality.

Great White Shark

Great white sharks live in South Africa, Australia/New Zealand, the North Atlantic, and Northeastern Pacific. Out of 949 confirmed unprovoked attacks by sharks on humans ever recorded, 351 were by great whites. 59 of these attacks were fatal. There were only 108 unprovoked attacks in 2022. 32 bites came from situations where sharks reacted to harassment of which only 9 were fatal.

Lion Fish

Lion fish live coral reefs in the tropical water of the South Pacific and Indian Ocean. These fish have over a dozen spines with powerful venom that causes extreme pain. Some rare cases include paralysis, shortness of breath and nausea. They are not known to attack people but injuries do occur when people get too close.

After learning about how these are some of the deadliest sea creatures in the world. Also how deadly they are and where they are located on the earth. Will you be able to still go to the beach?

10 of the Most Incredible Sea Creatures in the World

larsoave004 Science November 19, 2024Sea animals, sea creatures, Sea critterss 0 Comment

There are many amazing sea creatures in the big blue ocean including dolphins, whales, and sea turtles just to name a few. If you want to learn more about a few of these fascinating aquatic creatures, keep reading.

Dolphins

Dolphins are one of the most interesting and social sea creatures in the world. They are playful, kind, and helpful. Some people even refer to them as the dogs of the ocean because they are so playful. Dolphins sometimes even play with seaweed or other plants and shells laying around.

They are also very intelligent creatures. They have feelings and they care so much for their young.

Dolphins are also very fascinated in humans and other things. They have a desire to learn and grow just like us.

Sea Turtles

One of the most fascinating creatures is the sea turtle. Sea turtles are incredibly resilient creatures and have been around for 150 million years. They eat any green plants such as seagrass and algae.

Sea turtles lay their eggs in the sand and cover them up using their rear flippers. After about 2 months the eggs hatch and the baby turtles dig their way out into the world.

Also, many people when they think of sea turtles they think of the turtles retracting into their shells. But the truth is that sea turtles don’t actually retract into their shells. They have the muscles in order to do that but unlike other turtles and tortoises their shells are too small for them to fit into.

Seals

The first thing you should know about seals is that they can sleep on land or water. They usually prefer to only sleep on land when they have pups. The reason they sleep with their pups is to give them warmth.

Another cool thing about seals is that they surprisingly have ears. You can’t see them because their ears are actually hiding under their skin. But seals still have excellent hearing!

Sharks

These incredible creatures, like sea turtles, sharks have been around for 455 million years. They have actually been around longer than the sea turtle.

Another interesting fact about sharks is that they actually have no bones. Instead their skeleton is made of cartilage which is the same thing that your ears and the tip of your nose are made of. Surprisingly, with no bones sharks can still fossilize. That is why you can still see ancient shark bones.

Octopus

As you might already know octopi can fit into small tight spaces with ease. This is one of their most interesting attributes. The reason they can do this incredible thing is because they are 90% muscle and they have no bones which allows them to fit in tight spaces.

Also these incredible creatures have the ability to change color because they have many cells underneath their skin. These cells hold sacks that are filled with ether red, orange, brown, yellow, or black pigment. When the octopi stretches or squeezes the cells it changes the brightness or rapidness of the color. This makes it so you can see the color through the skin.

Whale

The first thing to know about whales is that they are huge! The largest type of whale is the blue whale. The blue whale can grow 90 feet or more and weigh as much as 24 elephants! It is considered the largest animal on the planet.

Something people don’t realize is that a killer whale is actually not a whale. It is a dolphin! They were named by ancient sailors because they saw them killing animals larger than them. Then the name stuck. Its real name is actually the Orca.

Whales also migrate about 10,000 (16,000 km) miles annually. They are considered one of the animals that make the longest annual migrations.

Manatee

These amazing animals are usually very heavy. They weigh between 880 and 1200 lbs. The reason they are so heavy is because they eat so much! One manatee eats about 100-200 pounds of food a day. They are herbivores which means they eat plants such as seagrass or other aquatic plants.

Cows and manatees eat so much grass in one day! That is why manatees are sometimes called the cows of the sea. They both graze along the floor eating grass and other plants.

Jellyfish

A really cool thing about jellyfish is that they actually don’t have a brain. Instead of having a brain they have a net of nerves. These nerves possess neutrons that send signals to the muscles to contract. When the muscles contract that is how the jellyfish swims.

Jellyfish are some of the most amusing creatures on the planet. There are over 150 million people studying different types of jellyfish. These scientists that study the jellyfish have learned so much about them, like how they don’t all have tentacles and how they change their behavior

Seahorse

The seahorse is an incredible creature that is not the best at swimming. They are so slow because they only have one tiny fin on their back that is the only thing that propels them forward. This gives them their reputation as the worst swimmer in the ocean.

Seahorses actually don’t have a stomach so they can’t digest some foods. Therefore they have to follow a very strict diet that includes very small fish, brine, and shrimp.

Eel

There are more than 800 distinct species of eel. Some well known species include the American eel, Ribbon eel, Japanese eel, and the Giant moray.

Most eels have very poor eyesight. But they have an unbelievable sense of smell and a nocturnal lifestyle. Because of these attributes the eel is one of the top predators of the ocean.

In conclusion, these are some of the most interesting, incredible, and unbelievable creatures of the deep and wonderful ocean! Their amazing attributes and skills make them a very fascinating topic to learn more about.

The Voynich Manuscript – a 600 Year Old Mystery

The Voynich Manuscript is a handwritten book, carbon-dated to the early 15th century (around the 1400s). It’s written in an unknown language that many call “Voynichese”. Many of the pages contain simple drawings of a variety of subjects. The entire codex currently has a total of 240 pages, however there are some that appear to be missing. Using the page numbering written inside of the book, and investigating the gaps between pages, it’s suspected that the whole manuscript once had around 272 pages in total.

A Brief Description

The manuscript doesn’t have an official name, only commonly referred to as “The Voynich Manuscript” after a man named “Wilfrid Voynich”. Voynich purchased the book some time in 1912. Later, in 1969, the manuscript made its way in Yale University’s Beinecke Rare Book and Manuscript Library. A few years ago, back in 2020, Yale University published the entire manuscript online for their digital library.

After many years of investigation and study, the language remains undeciphered. Many professionals and codebreakers attempted to decipher it during both world wars, but were unsuccessful.

The Investigation

As stated before, the pages had been carbon-dated to the early 1400s, sometime around 1404 to 1438. The manuscript had also been protein tested, showing results that the pages were made of calfskin, composed of at least 14 entire calf skins. Goat skin composes the binding and covers.

Polarized light microscopy had revealed that the ink the manuscript had used consisted of iron gall ink written with a quill pen. The ink was used for both the writing and the outlines of the drawings. Extra analysis provided evidence that the ink had traces of many different minerals, such as carbon, iron, sulfur, potassium, calcium, copper, and zinc.

Paint had covered the pages to color in the ink outlined drawings. All the colors have been analyzed. The blue paint was made of ground azurite with small amounts of copper oxide cuprite. The white paint consisted of calcium carbonate and egg-white. The green paint had copper-chlorine and atacamite. Finally, the red paint was made of red ochre, with traces of hematite and iron sulfide.

The text had many unknown characters, with some only showing once or twice. It reads from left to right, and there is no punctuation. Most of it is written in a single column with paragraph divisions and a jagged right margin. Over 170,000 characters are counted within the manuscript.

The illustrations and text both have characteristics of a European origin. For further evidence, the materials in the paint that was listed above consisted of minerals usually obtained from Europe in the suspected timeframe the book was written.

The History

Georg Baresch is one owner of the manuscript, being its first confirmed owner. Georg was a Prague alchemist from the 17th century. While the book was being stored in Georg’s library, a scholar named Athanasius Kircher had published an Egyptian dictionary. Georg sent a sample of the book to Athanasius, asking him to send him a translation. As the manuscript is not written in egyptian, the book was never translated. Athanasius acquired an interest in the manuscript because of this.

Athanasius asked Georg to send him the entire manuscript, but Georg refused. After Georg’s death, the book was given to his friend, Jan Marek Marci, who also happened to be friends with Athanasius. The manuscript was swiftly given to Athanasius.

The manuscript stumped Athanasius, so it was stored in the Collegio Romano library for two hundred years. The manuscript remained in this library until Victor Emmanuel II of Italy annexed the Papal States. Victor’s new government wanted to seize church properties, which included the library the manuscript was stored in. The book eventually made its way to a private library owned by the Society of Jesus.

Sometime in 1903, the Society ran low on money. The Vatican Library offered to purchase some books from them, which they succeeded in. 30 different books were shipped to the Vatican library. One of these books was the Voynich Manuscript itself. Wilfrid Voynich, the man listed before whom the manuscript was named after, acquired these books, and noticed the manuscript. He didn’t recognize the language, so for the next several years he urged scholars to attempt to decipher the manuscript.

Shortly after Wilfrid’s death, the manuscript was passed down to his wife, Ethel Voynich. Later, when Ethel died, it was passed to her friend Anne Nill. Sometime after, Anne sold the book to Hans Kraus, an antique book dealer. Being unsuccessful in finding an interesting customer, Hans donated the manuscript to Yale University, where it sits to this day still unsolved.

Flowers; Their Origins and Meanings

Roses

Origins

According to Greek mythology, the goddess of flowers, Chloris, created a new flower by breathing life into a woodland nymph who had died. Dionysus, the god of wine and plant life gave it a beautiful perfume, and Aphrodite, the goddess of beauty and pleasure, gave the rose its name by rearranging the letters of Eros, her son and the god of love and desire. Eros later gave a rose to Harpocrates, the god of silence, as a bribe to ensure he kept the indiscretions of the gods to himself. Hence, the rose became symbolic of secrecy, silence, and love. This story was carried on into Roman mythology, with the protagonists replaced by their gods, Flora, Venus, Cupid, and Bacchus, although Harpocrates retained his Greek name.

Overtime roses changed and adapted with the weather and other natural conditions and we got different rose colors. Of all the rose colors there is only one that is not fully natural, the multicolored (or rainbow) rose. This rose is artificially colored by its intake of water, therefore, it is not fully natural like the other rose colors.

Meanings

Each color or rose represents something different, for example, blue roses mean mystery and red roses mean love and admiration, purple roses mean passion and infatuation, burgundy roses mean devotion, lavender roses means unique love, deep pink roses means gratitude, medium pink roses means gratitude and congratulations, light pink roses means innocence and appreciation, salmon roses mean desire and excitement, orange roses mean fascination, peach roses mean thanks and gratitude, cream roses mean charm and thoughtfulness, white roses mean innocence and new love, yellow roses mean friendship, green roses mean good news and new beginnings, black roses mean grieving and mourning, and finally rainbow roses mean uniqueness, hope, and pride.

Regardless of their meanings and origins, when you give roses to someone it’s to show your care and gratitude towards them.

Irises

Origins

Like roses, Irises originate from Greek mythology too. Like with many flower names, the name of the iris comes from Greek mythology. In the Greek language, the word Iris actually translates to rainbow. And so the flower was a representation of the goddess of the rainbow, who was known as a messenger for Zeus and Hera.

The goddess of the rainbow would send messages from heaven to earth on the arc of a rainbow. And she was also a friendly companion tofemale souls who were on their way to heaven. Because of this, to this day, Greeks will plant purple irises on women’s graves to help guide them to their final resting place in heaven.

Meanings

Just like roses, each color Iris means something different. Purple Irises represent royalty, respect, and knowledge, blue Irises mean faith, devotion, and trust, black Irises mean honor, pride, and change, red Irises mean passion, love, and romance, pink irises mean love, passion, and deep bonding, yellow Irises mean passion and friendship, orange Irises mean bravery and exuberance, and finally white Irises mean purity and patience.

Heliotropes

Origins

Heliotropes are one of the few flowers which have a meaning not from Greek mythology but a legend. The legend starts by a guy liking this woman but doesn’t want to tell her so every day he sends her a purple heliotrope with a letter on it until finally the flowers read “Will You Date Me?” But on the final day the woman ended up passing away. The man was heartbroken but never gave up his love for her and every day he would visit her grave and give her a white heliotrope. One night he had a dream where she appeared and told him, “My love, if only you had told me sooner it was you. I love you and I always have and always will. I’ll wait for you on the other side.” He awoke from the dream and immediately went to her gravestone to thank her for giving him a sign that she knows he loves her. Eventually, the man ended up passing away and when he did he gave her a bouquet of purple Heliotropes and they finally got the happy ending they had hoped for in the afterlife.

This legend was taught to show how patience will always lead to happiness and each time he gave her a flower, their connection only grew stronger.

Meanings

Like any other flower, each color Heliotrope symbolizes something unique. Single purple Heliotropes symbolize success and dignity although a bouquet of them show admiration and adoration (what the man in the legend was trying to show with the bouquet and letters at first), white Heliotropes mean serenity and are meant to calm worries but they can also mean intimacy and everlasting trust and happiness with each other, white Heliotropes show purity and innocence; untainted hearts, souls, and minds, and can also mean honesty, elegance, and clarity (often given at memorial services, births, or weddings to mean a new beginning and love, respect, along with loyalty), finally, pink Heliotropes are a combination of innocence, playfulness, and sensitivity. Pink is not as intense as deep red so it can be used to show the wider range of possibilities that love has to offer.

Conclusion

In conclusion, all flowers have a variety of colors and meanings along with a unique and significant origin. These are only a few of the 400,000+ flowers so tell me what flowers you’re interested in learning more about and they might be my next article.

How Smart is a Rotting Brain:TWD

aceofcards Science May 13, 2024animals, pyschology, walkingdead, zombies 0 Comment

In the Walking Dead universe, we very quickly become familiar with “Walkers”, the zombies of this story. When A person dies in this universe they reanimate as a Walker and start attacking people without hesitation.

One thing about these monsters is their mysterious intelligence. Looking at the First Walking Dead compendium for the sake of simplicity. We see many events involving these beasts’ intelligence. Firstly we see very clear signs of limited recognition in which people are walking with the zombies undetected by covering their bodies in the entrails of a freshly killed walker, The zombies were unable to detect them because of the smell but once it wore off then they began to act hostile again suggesting that the Walkers can change perception based on new knowledge.

They also can recognize sources of food and even linger where they know food is such as hospitals and prisons. Some more unclear signs could be hearing recognition, mild speech, or group-based hunting. However, something very big we see is the act of someone “taming a zombie”. A good chunk into the book we meet a character named The “Governor” who is seen lingering with his family of zombies, he brings them food, and even tries to treat them like living people and it works. They seem to recognize that he brings them food and as such they don’t kill him but instead mind their own business and even show a small amount of submission toward him.

Looking at all of these points it seems fair to say that these creatures display very limited learning abilities, recognition via scents, familiarity with sources of food, and even a very very little amount of obedience or even symbiosis. Even though these feats sound respectable they are still outweighed by mental weaknesses such as almost no spatial awareness as they run into everything, inability to recognize threats with the number of times they walk up to someone and get slaughtered immediately, no sense of problem-solving abilities, and no concept of association that isn’t connected to food giving these creatures an intelligence level similar to a koala or cane toad which isn’t exactly very smart.

By coincidence however there is another much more interesting connection to intelligence, The Ophiocordyceps Unilateralis also known as the zombie ant fungus has strangely familiar connections to the behavior of these rotting beasts. The zombie ant fungus works by infesting the minds of worker ants through airborne spores, after the ant is infected it will become controlled by the fungus leading to the ant climbing above the nest from either a tree or some other stilt, The ant then becomes immobile and is consumed by the newly sprouted mushroom so that the cycle may repeat itself. Very Strange.
