Dr. Lesley Weaver, an alum of IU’s Department of Biology, has returned to campus as an Assistant Professor after her finishing her postdoctoral research at Johns Hopkins University. This past September, I had the opportunity to interview her about her experience as an early career researcher, setting up her lab, navigating IU in her new role as an Assistant Professor, and how the COVID-19 pandemic shift to online has simultaneously highlighted issues with and solutions to accessibility and diversity in academia.

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…
Are you sure you should eat that?
Amid this pandemic, you may be having conversations with family members similar to my own. I was talking to my brother about going to the grocery store and buying some eggs for baking when I was pretty strictly told that “no, you shouldn’t because the virus can be transmitted through food.” As a scientist myself, this was intriguing advice. So, I asked him to show me where he had read it. Sadly, nowadays when we are bombarded with news at every corner we turn, we were unable to backtrack his source…
Science, Eugenics, and Twitter
![[Picture of a flat-faced dog (a pug) sitting gracelessly and panting]](https://blogs.iu.edu/sciu/files/2020/02/fawn-pug-resting-on-floor-1289557.jpg)
On Saturday, February 16th, biologist and noted public intellectual Richard Dawkins tweeted about eugenics. Dawkins provided no context. No ongoing dispute he was inserting himself into. No obvious interlocutor. And certainly not anything as convenient as a few previous tweets to set the stage for this surprising announcement. As someone interested in science communication, genetics, and ethics, I find it worth exploring how he screwed up, how he didn’t screw up, and what any of this means for science…

The early bird gets the worm, part II: How behavioral ecology is connecting the dots between early-life stress and aging
This is the second post of a two-part series on a day in the life of a behavioral ecologist, which features the stories and research of members of Dr. Kim Rosvall’s laboratory in the Department of Biology. Click here to read the first post of the series! In Part I of this series, I discussed… Read more »
The cycle of life… and death… below your feet
As an ecosystem ecologist, I study how the cycle of life and death influences forest structure and changes over time. A walk in the woods might illuminate the forest’s dynamism as you observe squirrels tending to their buried acorn caches and listen to woodpeckers feasting on grubs. In contrast, the plant community may appear more… 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 »
Stellar psychology part II: what does signaling theory tell us about communicating with other life in the universe?
This is the second part of a series on extraterrestrial psychology. Read part 1 here! 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 »
The early bird gets the worm, part I: What can behavioral ecology tell us about female aggression and its underlying mechanisms?
This post is the first of a two-part series on a day in the life of a behavioral ecologist, which features the stories and research of members of Dr. Kim Rosvall’s laboratory in the Department of Biology. When most people imagine a scientist, they picture a person wearing a stark white lab coat and thick-rimmed… Read more »
