Peeking Inside the Chrysalis: Metamorphosis in 3-D

Emerging monarch

Metamorphosis. In the case of butterflies, it is nature’s version of the great makeover. A plump and slow caterpillar transforms itself into a chrysalis and, tucked snuggly away from the curious prying eyes of the world, metamorphoses into a colorful, graceful butterfly.

Growing up in Iowa, my sister and I had a summer tradition of stalking the milkweed plants in search of Monarch caterpillars. Once we captured our prey, we brought our new acquisitions home and placed them in lovingly crated Mason jar containers filled with milkweed leaves and sticks.  Over the next few days these lucky caterpillars lived in the lap of luxury with a constant supply of milkweed leaves. Once the time came for the caterpillar to transform into a chrysalis, we waited with baited breath for the butterfly to emerge.

As a child, those ten or so days I spent watching the unchanging chrysalis were filled with breathless speculation about what must be happening inside. Years later in biology class I learned all about the stages of butterfly development and what was really happening inside the shell of the chrysalis. This knowledge came with a little kernel of sadness though, because there was only one way for science to have figured out what was happening inside the chrysalis, and that way did not end well for the butterfly-to-be.

Wouldn’t it have been nice if we could take pictures of what was happening inside the chrysalis without disturbing nature’s makeover mid cycle?

Vegetable Gardening for Beginners

raised bedYou may have read several posts on this blog relating to the non-spring-like weather we have been experiencing here in the Midwest. Well, it’s still cold, but the weather has to break sooner or later and that concept has me so excited to get my garden going! Have you ever considered gardening? Are you new to gardening? You may have considered it and gotten overwhelmed by the details- What class should I take? What books should I read? What do I do?

I am here to tell you to Just Do It! There is nothing like watching your own food grow and then eating it. Things have been growing in the dirt since the beginning of time with no help from humans, so if you approach your garden project with this in mind and just aim to take it lightly, gardening can be really fun! I got started about four years ago only because someone at work left a flat full of different seedlings and a sign that said help yourself. I waited until the end of the day and only a few disappeared, so I carried the whole flat home on the bus and got started with just a 4´ × 4´ plot. Here are some beginner tips; just things I’ve learned over the last few years, that may help you get started. All these tips will be from a Madison, WI, perspective, but should be applicable anywhere in the midwest. Continue reading “Vegetable Gardening for Beginners”

Rats to the Rescue! From Landmines to Tuberculosis, These Rats Have a Nose to Help

treat3A little over a year ago, I wrote about many of the characteristics of the domestic rat that made them an unexpectedly good choice for a family pet. Since I wrote that blog, my family has welcomed three very personable rats into our home.

To my family, rats are funny, playful, treat-stealing companions. However, in other areas of the world, some distant cousins to our mischievous threesome have become real-world heroes. These rats help clear fields of landmines and, as if that were not heroic enough, significantly increase the number of diagnosed tuberculosis infections. Continue reading “Rats to the Rescue!

Science in the Service of Art

Three artists who use science as their starting point.

Galapagos Rice-Rat from 'The Zoology of the Voyage of H.M.S. Beagle'. This media file is in the public domain in the United States. This applies to U.S. works where the copyright has expired, often because its first publication occurred prior to January 1, 1923.

My recent blog conversation (blogversation?) with Michele about the book The Where, The Why and The How stirred me up to think some more about the topic of science-flavored art. That book was full of delightful examples of artists using science as their inspiration; however no matter the topic or style of art, the illustrations never strayed from _illustrating_ the science they referenced. Some were more fanciful than others, but none questioned their basic intent.

Now, in literature there’s an entire genre dedicated to “science flavored” writing that ultimately doesn’t serve to illustrate any actual science concepts. I’m speaking of Science Fiction, of course, and while some early entries in the SF canon erred on the side of scientific accuracy, later practitioners of the genre took great liberties with the science, always ensuring that it served their literary goal and not vice versa. I was raised on a steady diet of Stanisław Lem books, and probably as a result tend not to demand much realism from my fiction.

On thinking about it, I’m rather surprised that the same is in general not true of art.

Chuckle, It Is Friday

It is Friday. Maybe you have had a great week, a bad week, or maybe it was just average. No matter what kind of a week you have had, on Friday everyone should have something to chuckle about to end the week. Below are a few cartoons from our Cartoon Lab. I hope that you find one that tickles your funny bone.

The Where, The Why and The How: A science writer and a graphic designer have a conversation

0the-where-the-why-and-the-how-75-artists-illustrate-wondrous-mysteries-of-scienceWhen I first learned that I had won a copy of The Where, The Why and The How in the book lottery at ScienceOnline 2013, I couldn’t believe my luck. I never win anything, at least not anything that I actually want. And I wanted a copy of this book.

The book is beautiful to hold. The linen binding is beautiful, reminiscent of bygone days when book binding was a practiced art. The paper is thick and smooth, a tactile pleasure as you turn each page; the pages themselves sound substantial as you flip through the book. Even the smell of the book is delightful—bringing to mind the stacks of old books filling a great library, even though what you hold in your hand is a new work. The science paisley inside covers of the book are a delight to look at, comprising various science icons intricately woven into an astounding tapestry.

I was expectant when I opened the book for the first chance for a serious read. Continue reading “The Where, The Why and The How: A science writer and a graphic designer have a conversation”

Copper Containing Surfaces and Their Potential for Reducing the Spread of Infection and Antibiotic Resistant Gene Transfer

As a scientist and a jewelry artist, there are not that many occasions when my two passions overlap. As a geneticist, I find the evolution and spread of antibiotic resistant microbes to be fascinating in a “this is really cool and utterly terrifying” sort of way. As a jewelry artist, I love experimenting with new and different metals. Some of my current favorites are stainless steel, copper and bronze, which is an alloy of copper and tin. So you might be able to imagine my excitement when I came across an article in mBio discussing the public health implications of horizontal gene transfer (HGT) of antibiotic resistance genes on clinical and public touch surfaces made from copper alloys compared to those made of stainless steel (1).

Stainless steel: The unexpected, gene-transferring truth

Polishing stainless steelStainless steel is often used in clinical and public settings as work surfaces as well as other surfaces that are touched and cleaned often. Stainless steel is used in these applications for many of the same reasons I like it for jewelry: it is strong, resilient, relatively inexpensive, stain- and corrosion-resistant and will weather regular cleaning/exposure to moisture well. There is something about a gleaming stainless steel work surface that looks, well, sterile. But is it?

Uniquely Buried in a Wisconsin

WinterIt is winter in Wisconsin, and it has arrived with a blizzardy vengeance. My family and I are snowed in for the second day, and as I write this I am trying not to think of the twelve plus inches of snow that covers my driveway. I am afraid to measure the height of the drifts.

The world outside my window is beautiful. Tree limbs and fence posts are frosted in white. There is a LOT of snow out there, and that made me stop and think, there is an awful lot of uniqueness out there. IF every snowflake is unique. And according to a local Wisconsin snowflake expert, University of Wisconsin, Madison, meteorology professor Pao Wang, they aren’t. Continue reading “Uniquely Buried in a Wisconsin”
