Although we can directly weigh modern birds, we can’t do this with extinct birds–and we need to know body mass to understand their biology! The previous post on this blog reviewed a newly published PLoS ONE paper on how to accurately …
“How heavy was it?” Body mass is not just an intuitive way to compare the size of animals, but it’s also critical for understanding their biology. Numerous scientifically interesting attributes can be related to body mass, such as growth rate, …
Fossils are part of our planet’s natural heritage. These traces of organisms that lived long before the founding of any nation are essentially the only record of how we came to be. As such, the past few weeks have seen …
It has been one year since our inaugural post, and time has indeed flown by. In honor of this milestone, each blogger highlighted a favorite post from the last 12 months.
Sarah Werning picked her post on …
Yesterday I wrote about how rocks layers are aged. After rock layers are lined up and put in relative order, they are dated radiometrically to get their age in years. Terrestrial rocks are difficult to date using relative ages …
Tomorrow I’ll post an interview with Dr. Randall Irmis, a geologist and paleobiologist working on the Colorado Plateau Coring Project. Today, I offer some background information on the geologic time scale and why it is so hard to …
You probably noticed a few things about TheEGG: a recent decrease in blog post frequency and an overall focus on the algorithmic lens — especially its view of biology. You might also be surprised by the lack of discussion of quantum information processing: the most successful on-going application of the algorithmic lens. I actually first […]

The patients experienced better

"We just found one of our Kingsnakes doing something really cool."
It was 2006 and we had recently started radio-tracking about a dozen Kingsnakes (Lampropeltis getula) in a big chunk of longleaf pine forest in southwestern Georgia. Kingsnakes were fascinating to me because they were a big, recognizable species for which we knew next to nothing. In fact, this was

“But, right now, do you think I made you stronger or weaker?” “I felt the flash and as we talked through it… it made me stronger.” I can trace my interest in neuroscience quite directly to when I was nine and my teacher showed us a video of the famous Penfield Experiments (see above, I’m pretty sure […]

Many organisms, such as fungi and plants without seeds, produce spores as a dispersal mechanism. Spores are usually microscopic propagules, many of them are able […] Read moreThe post How spores get their boarding passes appeared first on Mapping Ignorance.
