Why Worry about James Webb?

Posted December 25, 2021 by Jennifer Sieben

If everything has gone according to schedule, the James Webb Space Telescope (JWST) launched on December 22 and is currently on its way to its final orbit. JWST is designed to be a revolutionary telescope, building on the accomplishments of both the Hubble and Spitzer Space Telescopes. With its infrared instruments, it will enable us to see stars that were previously hidden by dust and to even detect water in the atmospheres of exoplanets. Its huge mirrors will help us collect more light to study the very earliest galaxies and uncover more information about how our universe was formed. Yet, the JWST will still give us gorgeous images of the universe, like Hubble does…

Primates: Nature’s grounds keepers

Over the past few years, the iconic video below has become the face of orangutan conservation efforts: a young male orangutan confronting a bulldozer as it destroys the forest around him. Orangutan populations once stretched from the islands of Indonesia through Vietnam and into the south Asian continent. Fossils of orangutan ancestors have even been found all the way up into northern India! Today, wild orangutans can only be found in Sumatra and Borneo, two islands in Indonesia…

The Nobel Prize in Physiology or Medicine 2021

The question of how we sense the environment around us has fascinated humans for centuries. The first attempts at a theoretical understanding of the senses were discovered in the writings of early Greek thinkers in the sixth and fifth centuries BCE. However, the gap between our theories and our understanding of how our senses work is continuing to shrink. This year, the Nobel Prize in Physiology or Medicine was awarded jointly to Dr. David Julius and Dr. Ardem Patapoutian, two scientists who independently discovered mechanisms of how we sense temperature and touch…

Viral variants: What are they, and how do they form?

Because the COVID-19 pandemic has been raging for almost 2 years now, most people have heard of the different viral variants that threaten the effectiveness of full protection with vaccines. This topic can be confusing to anyone who is not familiar with viruses or virology. This article will: 1) help you understand what viral variants are, and 2) explain where they come from. Viruses rely on host organisms (e.g., people and/or animals) to make more copies of themselves so that they can infect more hosts. However, hosts typically mount an immune response to clear a virus, which creates a challenge for viruses to overcome…

Cicada mania at IU

If you’ve walked around Indiana University (or frankly, any woodsy area in Indiana) recently, you’ve probably seen the 17-year Brood X adult cicadas on sidewalks, long grass, trees, and buildings. If you are reading this post and you’ve been in Bloomington for a while, you may also remember the time this happened 17 years ago. Or, you might be like me, and this invasion has sparked a curiosity of wanting to learn more about cicadas…

The Origins of 420

This Tuesday is April 20th, otherwise known as 420. For some it’s just another day in the week, but for others it’s a much-anticipated and beloved holiday. However, have you ever stopped to consider how this pseudo-holiday came to be? A quick google search will provide a number of varying and amusing theories. Some of the most popular 420 stories include 420 as a police dispatch code for cannabis use, as the number of chemical compounds in cannabis (actually there are over 500), or the day of Bob Marley’s death (actually May 11th). However…

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?

A quick summary of the immune system and the COVID-19 vaccine

There are many strategies when it comes to developing a vaccine, but the idea behind all of them is similar. Vaccines are designed to pose a foreign invader, such as a virus or bacterium, to your adaptive immune system without causing you to be sick. Our immune systems are quite amazing, which also makes them quite complex. Here, we will focus only on a few aspects that are important for understanding vaccine development…

Against “the study”

Posted November 7, 2020 by Evan Arnet

[An image of gloved hands working with test tubes. The image has a large red X over it.]

Science journalists are always announcing the results of the latest study. The more bizarre and controversial, the better. A recent study is, almost by definition, cutting-edge research — what better way to tap into the pulse of science? Except, the latest and greatest research is just as often wrong. The concern is not simply with hype. Rather, the problem is the “study.” As a unit of scientific research, it leaves much to be desired, and for those who are unfamiliar with the practices of the scientific community, how to interpret a lone study can be deeply confusing.

A 70% chance to win? The tricky math of election forecasting

Posted October 24, 2020 by Evan Arnet

[two red and blue carton human figures are climbing a normal distribution curve that is decorated with the American flag.]

The election is almost here and the election forecasters are in full swing. As of October 23rd, the Economist gives Biden a 92% chance of winning, and FiveThirtyEight has him winning 88 out of 100 “simulated” elections. How should we interpret these claims? If you have a coin and you flip it a thousand times, and it lands on heads 500 times and tails 500 times then you may infer it has a 50% probability of landing on heads and a 50% probability tails. Sounds simple, except, we’re not going to run this election thousands of times, we’re only going to run it once.
