Pulling out an interesting little option from the 2008 Farm bill, the USDA is considering re-directing US produced sugar to ethanol production to drive up sugar prices. From what I understand, the US sugar industry is completely supported by farm … Continue reading →
A new report from the CRS reveals the sad state of what many believe is an impossible venture – “clean coal” that involves capturing the CO2 released as the coal is burned: http://thehill.com/blogs/e2-wire/e2-wire/293655-report-federal-clean-coal-power-project-faces-uncertain-future
IMF presents some new analysis of energy subsidies which I have previously wondered about. It is worth looking over: http://www.washingtonpost.com/blogs/wonkblog/wp/2013/03/27/imf-want-to-fight-climate-change-get-rid-of-1-9-trillion-in-energy-subsidies/ $25/ton as the cost of carbon seems low to me. $502 billion in US energy subsidies including this carbon tax..

For those who are confused about RFS, RINs, and other acronyms in my last post, I found a great summary on a new blog that we’ll add to our blogroll. Seems like he is making some nice posts of the … Continue reading →
As we’ve hinted at before, some interesting things are starting to happen with high corn prices, high RIN prices, the blend wall and ever compounding RFS requirements! We all know that corn prices have been high – so high in … Continue reading →

An interesting paradox: as we conserve more energy, we use more. We pointed out some research in the past on this effect, and some debate about the potential impact of this effect has surfaced in a couple places. First, there … Continue reading →
While we’ve discussed production issues with cellulosic a bit on this site (here and here), if John is right and we do scale up in the next couple years, whatever are we going to do with it all? http://farmdocdaily.illinois.edu/2013/02/ethanol-blend-wall-biodiesel-RFS.html They … Continue reading →

And is the land that is being converted from grassland to corn and soy the “marginal land” that people take about growing dedicated bioenergy crops? A new article in PNAS this week seems to answer “yes” to both these questions. … Continue reading →

I like how this post by Judy Endres explains the recent court ruling “overturning part of the RFS”. The devil is in the details: Although the court rejected EPA’s approach favoring overestimation of projected cellulosic biofuel production, the RFS itself, … Continue reading →
Today the EPA released revised mandated amounts of biofuel to be blended under the RFS legislation. To put these numbers in perspective I have taken the original requirements for cellulosic in the 2007 law and compared to the revised amounts … Continue reading →

Says a new report from the IEA.. What does this mean for alternative and renewable energy and climate change? Renewables become the world’s second-largest source of power generation by 2015 and close in on coal as the primary source by 2035. … Continue reading →
For biofuels to be economical, we will need some technology breakthroughs. In the US, the RFS is driving us to produce liquid fuel, usually with enzymes that convert sugars and starches in the biomass to ethanol or other liquid molecules … Continue reading →

With the development of statistical mechanics, physicists became the first agent-based modellers. Since the scientists of the 19th century didn’t have super-computers, they couldn’t succumb to the curse of computing and had to come up with analytic treatments of their “agent-based models”. These analytic treatments were often not rigorous, and only a heuristic correspondence was […]

Hey Julie,I hope you've had a fun week. I saw a new in-press publication with your name on it - "Smelling more or less: Investigating the olfactory experience of the domestic dog" - looks like a really great study, and so timely after my last post about dogs and olfactory enrichment! Looking forward to reading it (and all those other cool Learning and Motivation articles) over the weekend. So did you do your homework? Did you watch this clip from the Sydney Opera

Epigenetic analysis is one of the hottest areas in all of biological research. Covalent modifications to DNA, proteins, and RNA, without changing the primary sequence of these molecules, are known to epigenetically regulate numerous cellular processes and contribute to many important human disease phenotypes. One of the most intensely studied epigenetic modifications is DNA methylation ...
