    Benefits of Quality Sleep

    • Sleep is where the mind and body reset and process the information of the day, so with better sleep, individuals can have improved cognitive performance, memory, and executive functioning (Dewald et al., 2010).
    • Getting quality sleep results in better emotional regulation, improved cardiovascular and immune health, as well as reduces the risk of behavior problems and disorders (Kohyama, 2021).
    • Improved mental health and executive functioning (Kohyama, 2021).

    Tips to Get Better Sleep

    • Prioritize and value sleep i.e., think of it as something you need, rather than a luxury or privilege (Espie, 2022)
    • Sleep is personal. Find your routine that works for you and stay consistent (Espie, 2022).
    • Allow enough time to relax before bedtime and relax with a routine that works for you; it’s difficult to tailor sleep advice for every individual, so it’s best for an individual to determine a routine that is effective for them through trial and error (Hauri, 1991, p. 65-66).

    From The Moon to Mars! (Artemis Mission Timeline)

    To revive human exploration into deep space, it’s only natural that we learn more about our Moon before we venture further out of our Solar System. It’s been 50 years since we’ve sent astronauts into deep space, so these Moon missions will help scientists and engineers to develop and improve current infrastructures and systems for deep space travel (Creech et al., 2022). By studying geology and collecting samples from the Moon’s surface, we can learn more about “planetary processes, the impact history of our Earth-Moon system, and the history of our Sun” (Creech et al., 2022).

    I attached an infographic that I made for the Artemis mission. All the information on this infographic can be found on NASA’s website!

  • Color, Emotions, and Filmmaking

    Color, Emotions, and Filmmaking

    I’m making a short film! I’m taking Video Production (LMC3406) this semester, and it’s been an absolute blast! To be completely honest, it was the class I looked forward to the most every week. I love how human the filmmaking process is, and I found a lot of fulfillment working with my classmates and bringing our individual visions to life with one short film each lab (class).

    The final project for the class is to write, produce, and direct a short film about whatever we want (minimum 2 mins, maximum 10 mins). Since pre-production, I’ve wanted to write a story that’s relatable, whimsical, and simple/practical to execute, because I wasn’t sure I would be able to recruit enough people and/or schedule/organize filming around several people’s schedules. My short film is based on my own story. It follows two characters, my boyfriend and I, on an aquarium date! Even though I was more interested in cinematography than writing a complex story, I felt my short film could use a bit more substance, so towards the end, the two characters share this conversation about the fear of the future and living life fully. 

    For this film, I wanted it to feel nostalgic, wholesome, heartwarming, and bittersweet. I wanted the viewer to feel comforted and hopeful. While I’m not done editing my short film, I can show a comparison with stills and how color can change the mood of a scene. 

    These are some screenshots from Davinci Resolve, the video-editing software I’m using to film my project, and what you see here is the log footage and two color-graded versions of the log footage. 

    Screenshot of log footage from my short film
    Colograde Ver 1
    Colorgrade Ver 2

    In the first color-graded version, the scene is more warm-toned. The colors are vibrant, the yellows and oranges are strong and visible, whereas with the second color-graded version, the scene is more cool-toned. The colors there lean more blue, the skin appears pale, and the scene is less saturated and devoid of color. 

    Two researchers conducted a comprehensive systematic review of the results from 132 empirical articles on color-emotion connections. For instance, warm colors such as yellow and orange were “linked to positive and high arousal emotions (e.g., happiness, pleasure, fun, excitement, surprise)” (Jonauskaite & Mohr, 2025). In some studies, blue was found to be linked to positive (“comfort, happiness, relaxation”) and negative (“sadness”) emotions (Jonauskaite & Mohr, 2025). According to a different study, brighter and more saturated colors were found to be more pleasant than desaturated colors (Pazda et al., 2024).

    The colors of a scene can greatly affect the mood and evoke certain emotions. The next time you watch a show or movie, pay attention to the choice of colors and the possible intentions behind it!

  • The Einstein’s Ghost Tour Video!

    The Einstein’s Ghost Tour Video!

    This semester, I had the opportunity to film and edit a video for our event w/ the Atlanta Science Festival! We hosted the Einstein’s Ghost Tour, where attendees walk through a tour and learn about the research and the untimely demise of four scientists throughout time: Archimedes, Carl Wilhelm Scheele, Joseph Crocé-Spinelli & Théodore Sivel, and Marie Curie. I don’t get the chance to do media for an event often, so I’m really glad I got the chance to. Videography is one of my favorite hobbies, and I wanted to challenge myself for this event! 

    With this video, I learned a lot of new techniques and skills. I’ve been learning to edit with Black Magic’s Davinci Resolve, which is one of the video-editing software that the film industry uses typically for color-grading. I wanted to practice and learn color grading, so I recorded in Log format, a camera setting that captures footage in a flat, desaturated way to preserve maximum dynamic color range and information. There are so many tutorials on color grading on YouTube! Because of that, there are also several ways to color grade, and it got really overwhelming for a newbie like me.

    One thing I found to be challenging was working with footage from a low-light setting. I can’t really color-grade too much or really fix the dark video in post-production. I think it’s hard for me to reach my fullest potential with the kind of footage I had to work with. Another challenge I faced was not getting any footage of the guests’ faces, which I think takes away from the recap video, because we couldn’t see their reactions or expressions to our actors’ lines. Hopefully, the final video is still good!

    I really enjoyed the trial-and-error of the entire experience: figuring out which colors to bring out, how to bring out certain colors without sacrificing others, which footage to keep and which to scrap, etc. I enjoy the creativity and open-ended aspect of video editing! It’s so much fun putting together various video footage to evoke emotions and tell a story. I hope I achieved that with my video!

     

  • The Art of Boredom

    The Art of Boredom

    Introduction

    Recently, I found myself unable to do nothing, even for a few minutes. It’s like my body itches to be occupied. I think it feels uncomfortable to do nothing, which feels weird to admit. We live in a digital age where we have access to all kinds of information at our fingertips in a matter of seconds, probably more now than ever before. Things feel fast-paced, and we’re already moving on to the next big thing. After some introspection, I thought that it’s been a while since I’ve intentionally felt bored—whenever I’m bored, it’s so easy to find something for me to do. I ran into this video on YouTube, and it got me thinking, “Maybe I really should be bored sometimes!” I ended up doing my Final Speech for my public-speaking class on boredom. It’s time to be bored!

    Benefits of Boredom

    Boredom comes with several benefits! Here, I’ll discuss some of my favorite reasons to be bored.

    Boredom often signals when a situation isn’t working for us. Think of it like a redirection. Our urge to fight boredom can lead to positive change (An et al., 2023b). An example is when we’re doing something boring to us, say, sitting in a meeting that we don’t want to be in. As our mind wanders, we start thinking of better things we could be doing instead, or how we could better manage our time. As a result, another benefit of boredom is increased creativity (Mann & Cadman, 2014). This increase in creativity is often linked to daydreaming, which occurs when bored individuals cannot physically escape their situation, and their attention shifts from external to internal focus on their inner thoughts and feelings (Mann & Cadman, 2014). In Mann and Cadmen’s study, participants who completed a boring, mundane activity performed better on creative challenges than those who didn’t. Boredom facilitates exploration and opportunity because, using our desire for change, we explore alternate goals or information in our environment that we may have missed otherwise (Bench and Lench, 2013). 

    Boredom also serves as an opportunity for our minds to rest and reset. When we’re not actively doing anything, our brains can disengage. This causes the default mode network in our brain to kick in, prompting reflection and introspection, which helps us understand ourselves and the world around us (UniSC Youth Mental Health Researcher,  M. K. and P. of Y. M. H. & N. 2025). Boredom also “rebalances the nervous system and reduces sensory input to help calm anxiety” (UniSC Youth Mental Health Researcher,  M. K. and P. of Y. M. H. & N. 2025). You might feel anxious or restless from boredom, so we reach for something for the quick dopamine hit, but it has been found that constant stimulation, especially for our nervous system, can result in increased anxiety; this is because, our sympathetic nervous system regulates our fight-or-flight response, so keeping it on overdrive results in more anxiety (UniSC Youth Mental Health Researcher,  M. K. and P. of Y. M. H. & N. 2025). Simply, we’re better off embracing the boredom from time to time to allow our sympathetic nervous system to reset and recuperate.  

    Ways You Can Be Bored

    Say on your next walk to somewhere, e.g., class, put your phone away and take in your surroundings. Try doing this without any music, too! After completing a task, take 30 seconds to a minute to do absolutely nothing. Seriously! Turn your brain off just for a minute (or however long you like). It might feel weird in the moment, but I promise, it will be so refreshing and worth it! Try doing everyday tasks without external stimuli, such as no music in the shower or screens when eating. Or, take the mindfulness route by taking a few minutes at the end of each day to think of three things you’re grateful for. These are my recommendations, so I strongly encourage you to find practices that work best for you. The point is to remove external stimulus and to be present in the moment.

    Conclusion

    Now that you’ve read about the benefits and the ways to be bored, I must clarify that it’s not bad to alleviate your boredom. It’s not bad to want to be productive or reach for something when you feel bored. Know that choosing to be bored sometimes is part of intentional, healthy living. You are worthy of a break. Choosing boredom is choosing you!

  • Nature’s Architect and Engineer: Beavers!

    Nature’s Architect and Engineer: Beavers!

    Unironically, beavers are genuinely one of my favorite animals! With their chunky bodies, fluffy fur, five-toed webbed hind feet, five-finger hands, orange bucked teeth, and paddle-shaped tail, what’s not to love about them? They’re so cute! I recently watched Zootopia 2 in theaters, and there was a beaver character named Nibbles! I was THRILLED to say the least! I’ve never seen one in real life, so it’s on my bucket list to meet one someday. 

    Here’s a picture of my beaver squishmallows and bidoof plush! The beavers even have a paddle tail if you look closely. Bidoof is a Pokémon inspired by the beaver, and it evolves into Bibarel!

    Beaver Stuffed Animals and the Pokemon Bidoof
    Pictured are two beaver squishmallows and a Pokémon inspired by the beaver, Bidoof! I was not joking when I said I love beavers.

    Intro to Beavers

    Beavers are large, semi-aquatic rodents of the Northern Hemisphere (Brazier et al., 2020). There are two existing Beaver species: the North American beaver (Castor canadensis) and the Eurasian beaver (Castor fiber) (Brazier et al., 2020). We’re able to tell the difference between the two species based on the number of chromosome pairs: the Eurasian beaver has 48 pairs while the North American beaver has 40 pairs (Lavrov, 1983). Their distinctive features, such as the flat, paddle tail, webbed hind feet, constantly growing teeth, and dense fur, allow them to perform specialized behaviors: damming and tree felling that can transform landscapes, habitat, and water management (Brazier et al., 2020). Beavers use their construction ability to protect themselves from predators; they use their teeth to collect branches and trees to build their dams (“Beavers work to improve habitat”). 

    Beavers as Ecosystem Engineers

    Beavers are considered ecosystem engineers because their construction capabilities can alter, maintain, or create habitats by redistributing biotic and abiotic resources for themselves and other species (Rosell et al., 2005). There are three main types of lodge structures that beavers can build, and they select their lodge location based on water depth and bank characteristics (Rosell and Campbell, 2022). These lodges are where beavers take shelter, and beavers create underwater entrances to get to the dry living space, often called the chamber, which is where they rest, raise their young, and stay safe from predators (Rosell and Campbell, 2022). The three types are island lodge, bank lodge, and stick lodge (Rosell and Campbell, 2022). The island lodge is more commonly found in North America, and beavers build this type of lodge when the bank is low (Rosell and Campbell, 2022). Because the bank is low, beavers can’t dig a burrow into a bank, so they build upwards (Rosell and Campbell, 2022). “Bank lodges are found on the water’s edge and built around a burrow dug into the bank” (Rosell and Campbell, 2022). Finally, stick lodges are built from material extending from the shoreline (Rosell and Campbell, 2022). To create a more efficient access to food and building resources, beavers dig shallow channels, canals, which extend from beaver ponds (Brazier et al., 2020). Beavers build dams to raise the water level: ”habitats with deep, slow-flowing water keep them safe from predators” (Brazier et al., 2020). There are two types of dams that beavers may build: the primary and secondary dams (Brazier et al., 2020). The primary dam maintains the main lodge pond, which is much larger than the secondary dams; the secondary dams improve mobility and serve to move woody materials (Brazier et al., 2020). 

    Beavers are keystone species (Brazier et al., 2020). They literally change their habitat with their engineering instincts for their survival and needs, thus directly changing their habitat’s ecology. If you like to learn more about beavers in a more entertaining format, I highly recommend checking out Lindsay Nikole’s video about beavers! She’s one of my favorite animal content creators!

  • I love sharks, maybe you should too!

    I love sharks, maybe you should too!

    “Fish are friends, not food.” – Bruce from Finding Nemo. When I watched Disney’s Finding Nemo (2003) as a child, I was absolutely horrified by Bruce the Great White Shark. I was so afraid that when I went on family vacations to the beach, I would be wary of sharks patrolling. I would watch out for the triangular fin and didn’t want to stray too far away from the shore. Ironically, I’ve never seen the iconic Jaws (1975) movie. The director, Steven Spielberg, has said he “truly regrets” his portrayal of great white sharks and the movie’s contribution to the animal’s population decline. Even the author of the 1974 book Jaws, which inspired Spielberg’s movie, Peter Benchley, has apologized for the impact his book had on sharks and dedicated the rest of his life to shark conservation! Check out Benchley’s website–it’s awesome!

    I’m not sure when I became a big fan of sharks, but I think it might’ve been because I watched a YouTube or TikTok video about them, and since then, I love sharks!

    Background

    Sharks belong to the class Chondrichthyes, or cartilaginous fish, meaning their skeletons are made of cartilage, rather than bone like other fish (Chapman, 2017). Fossil records have shown that members of this class have been around since 400-450 million years ago, which also means that sharks are older than trees and some dinosaurs (Chapman, 2017)! Chondrichthyans represent “one of the most species-rich lineages of predators on Earth and they continue to play important functional roles in coastal and oceanic ecosystem structure and function” (Chapman, 2017). The Chondrichthyes class has two groups: Holocephali and Elasmobranchii (“Shark Species”). The Elasmobranchii group has 8 orders of sharks, so each order classifies the “biology, physical characteristics, and behavior of sharks in that order” (“Shark Species”). Check out the Shark Research Institute’s website to learn more about sharks from different orders (you can also click on a shark to learn more about them). 

    Sharks are typically found in marine habitats (although bull sharks, Carcharhinus leucas, may be found in estuaries and rivers in tropical/warm temperate regions), from shallow coastal waters and the continental shelf and slope to the deep ocean (Bennet, 2005). Sharks are highly diverse, with species ranging in size from about 20cm to over 18m (Dedman et al., 2024).

    Here are some fun facts! Whale sharks are the largest fish in the sea—they can grow more than 12m long and can weigh over 21 tonnes (Chapman, 2017). You can visit Yushan, the whale shark, at the Georgia Aquarium (the only US aquarium with a whale shark). I visited the aquarium two summers ago, and whale sharks are really just gentle giants. Greenland sharks are the “longest-lived vertebrate known, with recent studies estimating a lifespan of about 390 years, give or take 120 years” (Nielson et al. 2016). Isn’t it crazy to think a species of shark could outlive three human family generations? 

    Ecological Roles of Sharks

    It’s actually a misconception that all sharks are apex predators (Chapman, 2017). Their exact role in the ecosystem depends on the “species, region, age/size, behavior, and/or sex” (Chapman, 2017). Chapman explains that apex predators must occupy the highest trophic level, control the ecosystem from the top down, and influence the productivity of the entire system (2015). In addition, “macropredatory and large mesopredatory sharks often induce behavioral shifts in their potential prey through predation risk and possibly competitive interactions with other predators” (Dedman et al., 2024). This means that sharks can impact how prey feed, hide, or move. Most sharks do not uphold these behaviors and would be classified as mesopredators (mid-level predators); only a select few sharks are considered apex predators, i.e., “great sharks” (Chapman, 2017). Sharks are not simply large predators: they can fill ecological roles at varying trophic levels (Dedman et al., 2024). Their diets range from filter feeding (like whale sharks) to parasites to small crustaceans to classic big predators that eat fish, turtles, seals, and other sharks (Dedman et al., 2024). However, it is challenging to create a comprehensive “understanding of ecological roles and the importance of sharks because of the inherent difficulties of studying their interactions and the mechanisms through which sharks may–or may not–affect ecosystems” (Dedman et al., 2024).

    Sharks also have a bottom-up and/or facilitation role in ecosystems. Though research here is currently limited, we know that sharks move nutrients across great distances: “from pelagic environments to coral reefs, shallow to deep mesophotic coral reefs and vice versa, coastal oceans to estuarine waters, and across latitudinal gradients” (Dedman et al., 2024). These nutrients are deposited via “egestion and excretion or carcasses of sharks that die” (Dedman et al., 2024). It is worth noting that the ecological importance of this deposition needs to be further studied, as it remains unknown. 

    Threats to Sharks

    According to Dulvy et al.,”24% of shark, skate, and ray species are considered Threatened with extinction by the IUCN Red List’s Shark Specialist Group (2014). Targeted overfishing and bycatch (unintentional catches) contribute to the shark population decline (Shiffman and Hammerschlag, 2016). Shark fishing involves the sale of meat (for consumption), jaws (as tourist trinkets), cartilage and liver oil (as alternative medicine); the major reason for shark fishing is for shark fin soup (Shiffman and Hammerschlag, 2016). According to the Fisheries and Aquaculture Department (FAO), trade in shark parts is worth approximately US $1 billion annually worldwide (2010). Unfortunately, because of sharks’ slow growth, late maturity, and low reproductive rate, sharks are especially vulnerable to overfishing (Friedrich et al., 2014).

    Conservation Efforts 

    Raising awareness about shark issues and the destructive impacts human activities have on shark populations has been found to improve attitudes towards shark conservation (Friedrich et al., 2014). At a consumer level, we can consider purchasing sustainably sourced seafood or engage with campaigning for policy change (Friedrich et al., 2014). The image of sharks as fearsome predators greatly limits public engagement and support for shark conservation, which is due to cultural representations in media, such as Jaws and sensationalized media reports of shark attacks (Friedrich et al., 2014). Effective shark protection is rooted in “international strategy, changes to fisheries regulations, and tailored conservation tools (Friedrich et al., 2014). To determine effective conservation strategies, we must study ecological communities, species’ roles, and “the context of pervasive human presence in the oceans” (Dedman et al., 2024).
