Clear Vision Unveiled: How Do Contact Lenses Work?

by with No Comment Blog

At least 2.2 billion people around the globe have impaired vision, and of these people, 140 million wear contact lenses. There are two general categories of contact lenses: soft and hard (also known as rigid gas permeable or RGP). Soft contacts are made of flexible plastics that offer more comfort and stability than hard contacts but are more difficult to insert and remove. On the other hand, hard contacts have a longer lifespan and lower risk of infection, but it’s easier to dislodge them from the eye.

How Do Contact Lenses Work?

No matter if they’re soft or RGP, contact lenses have a fascinating science behind them. They sit on top of the cornea, the eye’s transparent outer layer. There, they correct the refraction of light. Refractive errors make it challenging for the eye to focus light how it usually does, which results in blurry vision, and eyewear (glasses and contacts) fixes this issue.

Figure 2: Diagram of the cornea

For example, myopia, commonly known as nearsightedness, is the eye focusing light in front of the retina instead of directly onto it. Contact lenses help you see clearly by adjusting the light rays to angle further back into your eye, right onto the retina.

Glasses Vs. Contact Lenses

Of course, glasses are another option for blurry vision. However, many prefer contact lenses because they move with the eye, meaning you can look around a space with perfect vision. Glasses often leave room at the edges that they can’t correct. Also, contacts are handy with outdoor sports as they won’t fog up or get wet, unlike glasses.

While it can take some time to get used to the feeling of weight on your eye, contacts are a fan favorite for various reasons. They’ve come a long way since being invented in 1888 and are so technologically advanced that only 1 out of 500 wearers get severe eye infections! Whether you wear them or are simply intrigued by the innovation behind them, contact lenses promise a clearer and brighter future for all.

Planet Nine: A Scientific Odyssey into the Solar System’s Hidden Giant

by with One Comment Blog

In the expansive reaches of our solar system, a captivating scientific conundrum has surfaced, beckoning the keen minds of astronomers to embark on an intellectual odyssey.

What is “Planet X”?

The concept of a ninth planet, occasionally referred to as “Planet X,” is not new. Its historical roots are entwined with previous astronomical speculations. The upsurge of interest in this idea, however, can be attributed to the groundbreaking research of astronomers Konstantin Batygin and Mike Brown, whose 2016 work laid the groundwork for Planet Nine’s resurgence into the scientific forefront.

The Kuiper Belt, a celestial hinterland residing beyond Neptune, serves as the epicenter of the Planet Nine conundrum. It is a region inhabited by icy objects, among which Pluto and Eris – one of the largest known dwarf planets of our solar system – are renowned inhabitants. Yet, within this remote realm, subtle gravitational tugs on Kuiper Belt Objects (KBOs) provide the first clues to the presence of a hidden planetary body.

Planet Nine defies direct visual recognition, lending it an enigmatic character that contributes to its allure. Its existence is deduced from the disturbances it causes in the orbits of KBOs, which lend distinctive properties to their elliptical paths.

“Planet X” Characteristics

Estimates suggest that Planet Nine could possess a mass ten times that of Earth, positioning it as a super-Earth-sized entity on the outskirts of our solar system. Presuming its existence, Planet Nine follows an elliptical orbit of remarkable eccentricity. It navigates a protracted journey, spanning thousands of terrestrial years to complete a single solar orbit. Given its staggering distance from the Sun, Planet Nine is expected to be a world shrouded in ice, with a substantial atmosphere to withstand the profound chill of its extraterrestrial habitat.

The scientific community continues its tireless quest to pinpoint Planet Nine. This relentless pursuit employs advanced telescopes and sophisticated data analysis techniques to survey the night sky, in the hopes of discerning the faint traces of this concealed celestial body.

The discovery of Planet Nine carries profound implications for the field of planetary science. It may elucidate the enigmatic deviations in the orbits of neighboring celestial bodies, shedding light on the intricacies of celestial mechanics and planetary formation. It may even shed light on undiscovered parts of theories we still know little about – gravity. Furthermore, the study of this ninth planet serves as a bridge between our solar system and the exoplanetary realm, permitting insights into the commonalities and distinctions between our planetary family and those found orbiting distant stars.

Planet Nine, the tantalizing cosmic mystery, exemplifies the scientific spirit’s relentless pursuit of knowledge. Its elusiveness, while complex, serves as a testament to the dedication of astronomers and their enduring quest to unearth the secrets of the solar system. As our technological prowess and understanding of the universe advance, we move ever closer to the resolution of this hypothetical ninth planet’s mystery. Until that moment arrives, the allure of the unknown, the thrill of scientific discovery, and the potential to redefine our comprehension of the solar system’s intricate dance continue to inspire the gaze of astronomers, directing us toward the realization of Planet Nine’s secrets and the recalibration of our cosmic narrative.

Perfume : A Scent-sational and Fascinating World

by with One Comment Blog

Have you ever wondered how perfumes work? Or why some scents make you feel happy while others make you feel sad? From the comforting aroma of freshly baked cookies to the invigorating scent of a pine forest, we often find that certain smells can remarkably transport us through time and space, awakening a cascade of feelings and memories. But really, how does it all come into play?

The History of Perfumes

Although France comes to mind when we think of perfume or fragrances, the ancient art of perfumery arose in ancient Mesopotamia. The world’s very first recorded chemist was a perfume maker named Tapputi, whose existence was recorded in 1200 BC in Babylonian Mesopotamia. Flowers, oils, seeds, leaves, and other plant parts were common ingredients in early perfumes.

Once mixed with water and other solvents, it would be distilled and filtered. Later on, perfume would reach Rome, the Middle East, and other European nations.
The reason perfumery is most associated with France is that in the 14th century, the French started the cultivation of flowers for perfume in the subprefecture of Grasse, which continues until this day. Grasse is now considered to be the world capital of perfume.

The Road to Make a Perfume

Most perfumes obtain their smell through the extraction of fragrant oils from natural sources like plants, fruits, and wood. Some even use substances from animals, like musk from male deer. However, scents that don’t occur naturally may be created by synthetic chemicals. The methods employed to extract essential oils include steam distillation, expression, and enfleurage.

These oils are later blended to produce a unique scent. Ingredients like alcohol, coal, and tar may be added to adjust or alter the strength of the scent. If the perfume contains a higher concentration of essential oil, it will be more fragrant and generally more costly. This is what differentiates fragrances from one another. 

The Emotional Ties to Scents

Perfumes work by releasing molecules into the air that we can smell. When we inhale them, these molecules bind to the highly specialised olfactory receptors in our nose, which can are able to detect thousands of different molecules. This binding will trigger a signal being sent to the brain, which will later correlate to a response.
Signals from sensory organs pass through the brain’s limbic system, which handles behaviours, emotions, and emotion-related memories.

The amygdala, a part of the limbic system, is responsible for emotional processing. It is also the part that connects emotions to memories. This is why certain scents can trigger strong emotions or memories.

So next time you wear a perfume, take a moment to appreciate the science behind it. And remember, the right scent can have a powerful effect on your mood and your memories.

The Grave Effects of Marijuana Consumption

by with No Comment Blog

Introduction:

Imagine you are at a social gathering and someone offers you a joint. You may have heard about the effects of marijuana from science classes and the media, but you may still be uncertain about what to expect. What happens to your brain and body when you embark on this journey? From the euphoric highs to the pitfalls of this green plant, in this exploration, we will dive deep into the intricate tapestry of marijuana’s effects on the brain and body, shedding light on both its allure and potential consequences, and examining the scientific side of this drug.

The Origins of Marijuana

Marijuana, also known as cannabis, has been a part of human culture for centuries. From traditional customs to modern recreational use, it has played a significant role in various cultures worldwide. While originally used for medicinal purposes, the use of this plant spread from Asia to Africa, Europe, and the Americas. In America, hemp, a variety of cannabis, was widely cultivated in the colonies of Virginia, Massachusetts, and Connecticut as a versatile resource for textiles, paper, and more. It is surprising to know that the early hemp plants had very low levels of the psychoactive compound THC. There are hints that ancient civilizations may have recognized the psychoactive potential of certain strains of the plant, potentially cultivating them for ceremonial or medicinal purposes. Evidence found in the graves of ancient shamans, including charred cannabis seeds, dates back to 500 BC and sheds light on the journey of cannabis through time.

The Compounds of Cannabis 

At the heart of marijuana’s enigmatic effects are over 500 distinct compounds in this green plant. The scent of this plant is due to the compound terpenoids which are responsible for the aroma of cannabis and other flowering plants. Studies show that terpenoids have diverse physiological effects, and they may contribute to the effects of cannabis. Moreover, cannabis contains unique compounds known as cannabinoids, with over 100 different types identified. The most well-known cannabinoid, delta-9-tetrahydrocannabinol (THC), is responsible for the psychoactive effects of cannabis, including changes in perception, mood, emotion, cognition, and motor function. CBD has been receiving increasing attention due to its potential therapeutic properties.  These intricate compounds work together by interacting with the endocannabinoid system within our bodies, a sophisticated web of receptors that control a collection of physiological processes. The fascinating part is how various strains of marijuana contain different concentrations of THC, CBD, and other cannabinoids and terpenes. The chemical makeup of these drugs affects the body and mind in outlandish ways and understanding these compounds is essential for unraveling the mysteries of marijuana’s influence on our lives.

Short Term Effects

Even though the consumption of cannabis has long-term effects, it also has short-term effects that are striking and immediate. Those who consume edibles, smoke, or vape often find themselves embarking on a unique journey. In the presence of euphoria and an altered perception of this drug, colors appear more vivid, music becomes a symphony of sensations, and even food tastes different. However, this altered state always comes

with a price: impaired coordination and reflexes, an increased heart rate, dry mouth, and bloodshot eyes are frequent sidekicks of the cannabis experience. After taking cannabis, daily tasks that require concentration and focus may also be adversely affected temporarily when taking marijuana. When high doses or individual predispositions are present, this journey can unexpectedly turn into anxiety and paranoia. As a result, your heart rate can increase, making you more likely to suffer a heart attack, panic attack, or stroke.

Long Term Effects:

Through many years of debate and extensive scientific research, the effects of marijuana on the brain and body come with many long-term effects that might alter your mind about the narcotic. Cannabis use has been linked to various adverse health outcomes. Studies have shown that prolonged marijuana use can impair cognitive functions such as attention, memory, and learning (short-term memory), especially in adolescents. Furthermore, research shows that the usage of marijuana can raise the desire for alcohol,

increase the risk of bleeding, increase appetite, reduce the effectiveness of antiviral drugs, and lead to addiction. Moreover, addiction can lead to a lack of motivation and a decrease in educational and occupational achievements. There is a growing body of evidence linking cannabis use with mental health problems, psychosis (which can mimic the symptoms of schizophrenia), and more harmful substances. 

Conclusion:

In conclusion, our journey into the world of marijuana has revealed a complex and intricate landscape that requires a deep understanding of its nuances. While this green plant has deep historical and cultural roots, it also carries a myriad of compounds that interact with the human body and mind in unique ways. From the euphoric highs to the potential pitfalls, marijuana’s effects are both captivating and consequential through the various compounds that are within this potent green plant.

Bioremediation: Hope in a Polluted World

by with One Comment Blog

In a world beset by pollution and environmental damage, bioremediation shines as a beacon of hope. This cutting-edge biotechnology harnesses the innate capabilities of living organisms, like fungi, to combat environmental crises. It presents an eco-friendly, cost-effective solution for cleansing soil, water, and ecosystems plagued by pollutants and toxins. In this article, we’ll explore the fascinating world of bioremediation, delving into its mechanisms, varied methods, and real-world applications.

Understanding Bioremediation

Bioremediation stands as a pioneering technique that leverages living organisms to restore balance to tainted environments. This innovative approach proves to be invaluable in addressing a spectrum of environmental challenges, from polluted groundwater to catastrophic oil spills. Be it the rejuvenation of a pristine forest or the rehabilitation of an industrial site, bioremediation promises an ecologically sustainable solution.

The Inner Workings of Bioremediation

At the core of bioremediation lies the stimulation of specific microorganisms, orchestrating nature’s own purification process. This method revolves around optimizing the conditions for these microorganisms to thrive, thus expediting the breakdown of contaminants. To achieve this, bioremediation employs various additives like molasses, vegetable oil, or even simple aeration. These additives serve as catalysts, invigorating microbial activity and creating a more hospitable environment for their growth.

Bioremediation can be implemented through two primary approaches: “in situ” and “ex-situ.” In situ bioremediation transpires directly at the site of contamination, while ex-situ bioremediation takes place elsewhere. The choice between the two hinges on factors such as climate, soil density, and the extent of contamination. Ex situ bioremediation may involve soil excavation and above-ground cleansing, potentially adding substantial costs to the process.

Advantages of Bioremediation

Bioremediation presents a range of compelling advantages as an environmentally friendly approach to tackling pollution and contamination challenges. By harnessing the natural abilities of microorganisms and minimizing disruption to ecosystems, it offers a cost-effective and sustainable solution. Bioremediation is versatile, capable of addressing various contaminants, and it generates fewer wastes, transforming pollutants into harmless byproducts. It boasts long-term effectiveness, adapts to site-specific conditions, and enjoys regulatory support in many regions. Moreover, this method promotes energy conservation and reduces the risks of accidents.

A Remarkable Bioremediation Case

A striking example of bioremediation’s success unfolded in the aftermath of the 1989 Exxon Valdez oil spill. This catastrophic incident saw the Exxon Valdez oil tanker run aground off Alaska’s coast, resulting in the release of approximately 11 million gallons of oil. As the world grappled with the enormity of the spill, bioremediation emerged as a promising solution.

Both the Environmental Protection Agency (EPA) and Exxon Mobil Corporation initiated experiments with various compounds to mitigate the disaster. Initial tests with bioremediation yielded promising results. Between 1989 and 1990, over 100,000 pounds of fertilizer were applied through more than 2,000 applications to the affected areas. By mid-1992, the cleanup was declared complete, with the fertilizer successfully breaking down nearly all the oil compounds.

Easiest Example of Bioremediation

Composting can be perceived as a variant of bioremediation known as biodegradation. It transforms food waste into fertile soil, reducing the strain on landfills and contributing to a more sustainable environment.

Conclusion

Bioremediation stands as a powerful fusion of science and nature, furnishing humanity with a formidable tool to combat environmental pollution. Its reliance on natural processes, minimal disruption to ecosystems, and cost-effectiveness position it as an exemplary solution for a world in urgent need of environmental healing. As we confront the challenges of pollution, bioremediation serves as a testament to our capacity to harness nature’s forces to mend the damage we’ve inflicted upon the Earth.

Unlocking the Brain’s Response: Exploring the Impact of Social Media

by with One Comment Blog

The influence of social media on our brains is intricate and far-reaching. From the exhilarating ping of a notification to the insidious erosion of our attention spans, the digital realm weaves a complex tapestry of effects that can awaken pleasure centers, rewire our focus, and even cast shadows on our self-perception. In a world where tweets and posts hold immense power, examining the multifaceted impact of social media unveils a captivating story that reveals the inner workings of our minds. In today’s world, social media has become a pervasive platform for human interaction, with both beneficial and detrimental impacts on the mind. This article delves into the complex landscape of how social media usage affects the brain, examining the cognitive and emotional aspects that underlie its impact.

Neurotransmitters and dopamine release:
Social media usage triggers and releases dopamine, a neurotransmitter associated with it. This creates a pleasurable sensation similar to accomplishing a task. This pleasurable sensation can be addicting, leading to an increased reliance on social media. Thus, it reinforces the brain’s desire for rewards and can lead to addictive behavior that is identical to substance abuse. Users who receive likes, comments, and positive feedback may become compulsive about checking social media platforms to maintain the pleasurable sensation.

Neuroplasticity and Attentional Change:
Our brains have the incredible ability to adapt and change in response to our experiences. Since social media is constantly changing content, it stimulates our brains to reorganize the neural pathways related to our attention. This is known as neuroplasticity, and it allows us to quickly adapt to our environment. This adaptation is constantly challenging our brains to rewire themselves and can lead to a preference for processing short, visually appealing information. This may alter the neural circuits connected to our ability to concentrate for extended periods. As a result, we may become accustomed to brief engagements, which could make it difficult to focus on tasks that demand deep contemplation.

Social Comparison and the Brain’s Social Circuitry:
Social media can sometimes lead to negative emotions due to the constant comparison of one’s life to the curated online personas of others. This can trigger negative feelings as the brain detects disparities between reality and idealized virtual representations. As a result, the brain can activate regions linked to harmful effects, contributing to feelings of inadequacy, envy, and compromised self-esteem.

Cortisol Response:
Frequent use of social media, particularly in negative situations or comparing yourself to others, causes the brain to respond to stress. This reaction involves the hypothalamic-pituitary-adrenal (HPA) axis to activate, which results in the release of stress hormones such as cortisol. This constant release of stress hormones can have detrimental effects on memory, learning, and emotional regulation. Continual exposure to upsetting content, such as unsettling news or online conflicts, can worsen stress levels and negatively impact overall well-being.

Impact on Adolescent Brain Development:
Adolescence is a crucial period for the ongoing development of the brain, especially in areas related to decision-making, impulse control, and emotional regulation. Overuse of social media during this developmental phase can interfere with the brain’s structural and functional connectivity. Heavy social media use among adolescents may result in changes to brain regions that are responsible for self-regulation and social cognition, which could potentially influence their socio-emotional development.
The fusion of social media and the brain underlines a complex connection that shapes cognitive, emotional, and developmental processes. Grasping the interplay between neurotransmitter modulation, neuroplasticity, social comparison, and stress response. In a time where social media is the norm, understanding the brain’s response to social media empowers individuals to better understand.

Tinnitus: Never-ending Noise

by with No Comment Blog

Hearing is one of our five senses, making our ears a vital part of our body. The ear consists of three parts: the outer ear, the middle ear, and the inner ear. When the outer ear picks up a sound, it travels through the external auditory canal and hits the eardrum, which then vibrates. These vibrations travel to three bones in the middle ear, known as the ossicles, where the sound gets amplified. Finally, the waves reach the cochlea in the inner ear and get converted into electrical impulses, which the brain translates into sound.  

This process is necessary for everyday life. Unfortunately, due to the delicate nature of the ear, this process can easily be disrupted. For example, exposure to loud sounds can damage the ears’ nerves, causing hearing loss. However, this can also cause something else: tinnitus. 

Tinnitus is the result of damage to the inner ear. Repetitive exposure to loud noise damages the tiny hair cells in the cochlea, which are responsible for sending electrical impulses to the brain. When the cells are bent or broken, they transmit random, spontaneous signals to the brain. The brain receives them and creates phantom noises – sounds only in the head with no external source.

Most cases of tinnitus are caused by hearing loss, which often happens as people age. 24% of people aged 65 and above have tinnitus. However, hearing loss can be accelerated by frequently being in an environment with loud sounds. These environments range from construction sites to blasting music through headphones. 18 – 29% of youth worldwide subject themselves to dangerous volume levels daily. 

Tinnitus can cause different kinds of phantom noises: ringing, buzzing, roaring, clicking, hissing, and humming in the ears. It can be present all the time or come and go. It can be in one ear or both. It can be loud or soft. 

Tinnitus may vary from person to person, but no matter how it presents, it proves to be unpleasant.

About 750 million people around the world have tinnitus. Most people with it lament that they can’t have silence anymore. The constant sound in their ears can even cause anxiety and depression. Some use background noise, such as TV or music, to drown out the noise. Tinnitus can be ignored sometimes, but the cold, hard truth is that tinnitus is permanent. There is no cure. 

So, the best method of protection is prevention. Tone down the volume of your music when you use headphones. Wear earplugs when you’re in a loud environment like a concert. Regularly exercise and eat healthy to prevent tinnitus caused by obesity or blood vessel disorders.

The world has gotten louder. Noise surrounds us constantly, and it can be hard to get a moment of silence. By protecting your ears, you protect your peace as well.
