Water is essential to life on Earth. So, if we are searching for life off-world, it would make sense to look for signs of water. Astronomers have been doing exactly that: employing different methods to find the first signs of life outside of our own world. Until recently, it wasn’t known whether there is water… Read more »

Can science be value-free? The “gap” argument
If scientists are in the business of facts, is there still space for human values? Like many other scientists-in-training, I used to think of the sciences as ideally free from societal values, such as environmentalism and feminism. Sure, our ethical or political biases might guide what scientists study or how others use that knowledge. But,… Read more »
What music does to your brain: A neuroscientist’s perspective
Why do we like music? Music is interwoven into almost every aspect of our lives. We hear it at the grocery store and in every single video we watch. We listen to it when we exercise, and we pay boatloads of money to go see our favorite artists in concert. We love all kinds of… Read more »

Deceiving with doubt: How industry denies scientific evidence on the dangers of pesticides
The bias of industry-funded research is pervasive and well-documented. When industry funds a study, it is more likely to produce pro-industry conclusions than is a non-industry funded study. Companies regularly use this pro-industry science to cast doubt on research that hurts their bottom line. Classic cases come from the tobacco and fossil-fuel industries, challenging evidence about the… Read more »
Winter makes me SAD: The biological story behind seasonal affective disorder and its potential treatments
As fall transitions into winter, all animals, including humans, must acclimate to colder weather, shorter days, and less sunlight. In many northern latitudinal regions across the globe, winter is often characterized by overcast skies and snowy days, in which little to no sunlight reaches life on the ground. Colloquially, some people report having the “winter… Read more »
Kissing, hand holding, and somatotopic organization in the brain
Have you ever wondered why humans express affection by kissing and hand holding? As with most things in life, the more you think about it, the weirder that it seems. Here’s an interesting insight from neuroscience that is fun to think about next time you decide that you want to over-analyze your love life even… Read more »
Stellar psychology part II: what does signaling theory tell us about communicating with other life in the universe?

In Part 1 of this series, I discussed how the interdisciplinary field of evolutionary psychology can help us explore similarities between the human mind and possible extraterrestrial ones. One common potential feature is how we search for resources, which often… Read more »
Seeds, Cyanide, And Medicinal properties (SCAM)
This post was written by IU undergraduate student Yiling Dong. It is the third in a series of featured stories written for a ScIU in the Classroom collaboration with Dr. Cathrine Reck in the Department of Chemistry. “Good source of B17” sounds legit, right? A quick internet search will lead you to thousands of results touting the anti-cancer benefits… Read more »
The Research Domain Criteria (RDoC) initiative: A brief look
Even for non-researchers, it is important to be informed about the various initiatives that change the way we do science and, ultimately, the way scientists choose to spend government dollars. In the wake of the 10-year anniversary of RDoC’s inception [1], I would like to unpack this commonly misunderstood acronym that is popping up in… Read more »
