5:07 AM | An Abnormal Perspective To Climate Change
I consider myself an environmentalist, I’ve always been deeply concerned with the protection of our planet. By starting a garden, signing all of Green Peace’s petitions, and co-leading an environmental club at school, I’ve come to be mistaken for a green-thumbed-hippy. In fact, so much of my life has revolved around ways to build a […]

Before I really get into this piece, I just want to warn you that after reading it, you may never look at some of history’s most honored figures the same way ever again. That being said, let’s start off in the present. Next Tuesday, November 4th, Americans will vote in the midterm elections to decide the political fate of the American Congress. As usual, underhanded, and just downright offensive mud-slinging tactics have been being used for political gains all over the

4:06 PM | How An Abandoned Walmart Became America’s Biggest 1-Floor Library
It’s no secret that Walmart stores are big. Really big. The average Walmart takes up about as much space as two-and-a-half football fields. According to international supply chain consultant MWPVL, Walmart stores covered a whopping 721 million square feet of retail space in the United States in 2013. That’s an area almost 10% larger than the entire city of Manhattan (661 million sq. feet). And when a Walmart location closes, it often remains vacant for long […]

9:15 AM | An Optical Clearing Technique for Plant Tissues Allowing Deep Imaging and Compatible with Fluorescence Microscopy
In this new article in Plant Physiology, an effective new tissue clearing method is used in plants with impressive results. I think this could be easily incorporated for use by undergraduate students. Previously developed as "Scale" method for use in animal tissues, the results were similarly effective (http://www.nature.com/neuro/journal/v14/n11/full/nn.2928.html).
