1:20 PM | Special Issue: Functional-Structural Plant Modelling
A number of research groups in various areas of plant biology as well as computer science and applied mathematics have addressed modelling the spatiotemporal dynamics of growth and development of plants. This has resulted in development of functional–structural plant models (FSPMs). In FSPMs, the plant structure is always explicitly represented in terms of a network of elementary units. In this respect, FSPMs are different from more abstract models in which a simplified representation of […]

9:16 AM | Eva’s endeavours: a professional path in plant science inspired by Norman Borlaug
“…I wanted to contribute in a similar way” – Eva Weltzien   Learning about the work of Nobel laureate, Norman Borlaug, in high school inspired Eva Weltzien to become a plant breeder so she too could contribute to improving the living conditions in the developing world. Today, Eva is a Principal Scientist in sorghum breeding and genetic resources at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in Mali. “Not only did […]

1:39 AM | First Class in the Books
The state fair is over indicating the end of summer and the beginning of a new semester. I taught my first class today, which of course means I basically met the students and introduced them to the course. In other words, we went over the syllabus…kind of. The course I am talking about is Eukaryotic Microbiology, an upper division course that focuses/uses the primary literature to teach students about eukaryotic microbes, scientific thinking, argument, etc.The third slide in this lecture […]

10:31 PM | President Obama: We Will “Degrade and Destroy” the Islamic State
Following confirmation today of the authenticity of a video that surfaced yesterday showing the beheading of American journalist Steven Sotloff, a number of U.S. officials took the opportunity to sound off. Primary amongst these figures was, of course, President Obama, who spoke about the video and the threat of the Islamic State at a news conference earlier today. “The bottom line is this, our objective is clear and that is to degrade and destroy (Islamic State) so that […]

8:42 PM | The Company Put In Charge of Restoring Egypt’s Oldest Pyramid Is Destroying It
4,600 years ago, the ancient Egyptians built the Saqarra Pyramid as a tomb and monument for Pharaoh Djoser, who ruled from 2686–2613 BC. The Pyramid is composed of 6 limestone “steps”, reaching a total height of just over 200 feet. The inside of the pyramid is a complex system of corridors, culminating in an elaborate granite and marble burial chamber. But the sands of time took their toll on the pyramid, and during the 20th century, restoration […]

5:16 PM | Did You Know… The First Video of Earth from Space Was Captured In 1946?
Most people have heard of the Space Race, a period of about 20 years from the mid-1950s to the early 1970s when the United States and Russia feverishly developed their space programs in a constant attempt to one up each other. The race was kicked off in earnest by the Russians when they launched Sputnik (the world’s first artificial satellite) on the evening of October 4, 1957. What many people don’t know, however, is that nearly 11 years before Sputnik, a team of

11:24 PM | The Physics Behind Why Cats Always Land On Their Feet (Video)
Almost everyone knows that cats have an extraordinary ability to land on their feet, even if they start out upside down. But how are they actually able to do this? Destin, founder of the popular youtube channel SmarterEveryDay, recently broke down the science behind how cats are seemingly able to always land on their feet. He posed the following question: How does a cat go from feet up to feet down in a falling reference frame without violating the conservation of angular […]

8:32 PM | The Islamic State Just Beheaded A Second American Journalist
Last month, the Islamic State released a video in which one of their fighters beheaded American journalist James Foley. At the end of that video, the militant group showed images of Steven Sotloff (another kidnapped American journalist), warning that he would meet the same fate if the United States refused to concede to the terms being by the extremist state. Now, it would seem that they have followed through on that threat. Earlier today, an Islamic State video surfaced that […]

6:33 PM | More Than A Third of Germany’s Wild Boars Are Highly Radioactive
On April 26, 1986, an explosion and fire at the Chernobyl Nuclear Power Plant in Ukraine (which was part of the Soviet Union at the time) released massive amounts of radioactive particles into the atmosphere. Helped along by wind and rain, these particles quickly spread all across Europe, reaching as far west as Spain and France. Now, 28 years later, the lasting effects of this nuclear disaster are still very evident. Wild boars are fairly common throughout Germany, and are […]

5:31 PM | Multiscale digital Arabidopsis predicts individual organ and whole-organism growth
How do you model a plant? By modeling pieces and assembling them in a meaningful way. Here's a multiscale model that works. From the abstract:"Our model brings together gene dynamics, carbon partitioning, organ growth, shoot architecture, and development in response to environmental signals. It predicted the biomass of each leaf in independent data, demonstrated flexible control of photosynthesis across photoperiods, and predicted the pleiotropic phenotype of a developmentally misregulated […]

12:03 AM | Forget Everything You Thought You Knew About “Horsepower”
Every time the newest model of truck or car comes out, the car manufacturers loves to tell you how much “horsepower” the vehicle has, conjuring up visions of muscular stallions galloping through the countryside. But I put the term “horsepower” in quotes because these visions are misleading. See, in our modern world, horsepower is simply a scientific unit that we accept as a standard. But to understand what it actually means, you have to understand where it actually […]

8:53 PM | Salamander Snapchats
With the school year starting up again, it means that the undergraduate crew that I work with in the laboratory at Ohio State are back on campus. They are great to work with. Really great. One of my favorite things about them, aside from their work ethic and trustworthiness, is that they have a fantastic collective sense of humor. Because levity is a big part of my own personal work environment, I encourage joking around extensively while doing scientific work. One of our salamander […]

7:59 PM | The Controversial Origins of Labor Day
On the first Monday of every September, we take a day off to honor the social and economic achievements of American workers and pay tribute to the contributions they make towards the prosperity of our great country. There are conflicting reports, however, as to who actually proposed the original idea for Labor Day. For many years, it was believed that the holiday was proposed in 1882 by Peter J. McGuire, general secretary of the Brotherhood of Carpenters and Joiners (one of the

7:18 AM | Breakthrough in the understanding of plant growth and development
Plants grow through cell division, cell elongation and differentiation of cells within tissues. These processes provide the structure of the plant. At the same time, plants can react very quickly to stimuli: the shoot bends towards light, and roots respond to gravity. “For the first time, we begin to understand how those quick responses can combine with the processes that preserve the structure of the plant, in an interplay between the hormone auxin and regulatory proteins”, says […]
