Who makes the longest sperm on Earth?

The drive to reproduce has led to many of the flashiest traits observed in nature. For instance, male deer use antlers to fight one another for access to female mates, while male peacocks display their extravagant tails to impress peahens. These are examples of sexually selected traits, or traits that increase reproductive success. Sexually selected traits evolve because they increase “fitness”…

Fieldwork codes-of-conduct

Field scientists often work in isolated, unsupervised, or otherwise dangerous locations. For instance, I used to work along remote streams with limited access and communication with my institution. These secluded environments can create conditions that exacerbate sexual harassment and bullying, from fellow field scientists or other people encountered in the field. This can lead to unsafe situations, particularly for non-male students and those belonging to marginalized groups. As a striking example of these hostilities, approximately 70% of women scientists have experienced harassment while doing fieldwork and one in four have been assaulted. Scientists at remote field sites can also experience hate symbols, threats of violence, or verbal abuse about a disability from people they encounter…

Do extreme floods and droughts cause more extreme floods and droughts?

Extreme floods and droughts are considered to be one of the greatest challenges to society in the 21st century. Historically, they have led to the collapse of civilizations, fatalities, and economic losses. In Indiana, recent droughts, such as the drought of 2012, have affected agriculture and water supplies. Recent flooding, such as summer 2021’s disasters in downtown Bloomington, have damaged businesses and homes. Now, the prevalence of these extreme events is increasing around the world; heavy rainstorms are increasing the severity and frequency of floods, while warming temperatures and a thirsty atmosphere are making droughts more severe…

Do scientists get bad grades?

I wasn’t accepted into grad school when I first applied during my final year of college. The emails beginning with “We’re sorry to inform you” trickled one by one into my inbox, and I spent time frantically trying to figure out my post-graduation plans, since they were previously just ‘grad school.’ Fortunately, most of these emails had good suggestions about actions to take over the next couple of years, but one piece of feedback stung a little more than the rest. One program noted that while I had spent time doing research, my science grades were ‘quite poor.’ Honestly, they weren’t wrong…

Rain-on-snow: I’m melting!

In mid-February 2021, Bloomington, Indiana was hit by a winter snowstorm that dropped several inches of white, fluffy snow around town. Schools and businesses closed. However, as other people were wondering “How will I get my car out of the driveway?”, I caught myself wondering “Will it rain soon?” What? Why? Rain-on-snow melt events have been receiving a lot of attention in scientific articles I have been reading. Aptly named, these events occur when a warm rain falls on an existing snowpack…

Work-life balance

I am writing about work-life balance, the subjective idea of basically having a life outside of our job or schoolwork. Experts say that a healthy work life balance is when we are able to fulfil our responsibilities to our jobs, families, and other parts of life that are important to us. It has been the buzz on social media lately. Why? It seems at times there is almost an expectation to constantly be working, known as “hustle culture.” This can be fed by many things including changes in job demand, a fast-paced work environment, and the inability to escape work because of that darn internet. People early in their careers have not been satisfied with this and are pushing to discuss better balance…

Particle physics goes virtual through pandemic difficulties

Phineas and Ferb (in the funny Disney cartoon) had it right when they wondered what could be done over a 104-day summer vacation. There is a lot to do, such as go on a trip, get ice cream, spend weeks on end floating in a pool, or doing particle physics research. However, the COVID-19 pandemic has shifted everything in life, resulting in many of these plans being canceled this past summer. Wait! Go back! Why would any student want to spend their summer, their solitary free time during the year, doing particle physics research? Moreover, how would that work during a pandemic, when the university is completely shut down?

Five skincare ingredients for fall and winter

Making sure your skin is properly hydrated and moisturized is essential for healthy skin. However, with Fall and Winter upon us, this weather can throw us off balance! We have all experienced that uncomfortable feeling when our lips are chapped, our cheeks are red, and our face feels tight or dry when walking through the blustery cold. With so many products on the market, it can be impossible to know what ingredients to look for. Depending on your skin’s needs, you may benefit more from certain ingredients over others. Some people suffer from dryness whereas others experience dehydration…

Science with Nemo: Ethics of Care in Animal Research

We are all familiar with the plot of Finding Nemo: a scuba-diving dentist takes a small clownfish, Nemo, from a reef, keeps him in a fish tank in his office, and Marlin (Nemo’s father) goes on a whirlwind adventure to rescue his son. Obviously, Disney’s creative fiction is just that — fiction. However, many millions of fish are kept in tanks in the real world, for both recreation and research. Although we cannot know the fate of home-kept fish, for fish used in scientific research, there are specific rules for ethical treatment and proper care for fish of all kinds. How and why do scientists use fish in research anyways? 

Cancer cells and their invisibility cloak

I remember being mind blown when I first read about how Harry Potter was able to disappear into alleys by wearing his invisibility cloak. The idea that someone could hide in plain sight always fascinated me as a child. What if I said that this happens right in the human body, where certain cells are able to use an invisibility cloak to camouflage themselves? You read it right: cancer cells have this extraordinary ability to hide in plain sight in the body. But, scientists are working on ways to get cancer cells to come out of hiding and to target them for destruction…
