A website, ScienceDebate.org, submitted a wide range of questions to Barack Obama and Mitt Romney about their plans for science and technology, and the answers, shown in a side-by-side comparison, are interesting, though in general they demonstrate the ability of politicians to speak for a long time without saying much.
This ability to blather is especially apparent to their answers to the question 12: “What should America’s space exploration and utilization goals be in the 21st century and what steps should the government take to help achieve them?” Neither candidate adds much to what was said in the Republican and Democratic party platforms, making it obvious that neither really cares or knows that much about this subject.
Overall, however, the answers do reveal the basic and fundamental differences between the two candidates, which can be seen in their answers to the very first question about encouraging innovation:

Another planet has been found in the habitable zone
Planets without end: Another planet has been found in the habitable zone.
Gliese 163c could have a size between 1.8 to 2.4 Earth radii, depending if it is composed mostly of rock or water, respectively. It receives on average 40% more light from its parent star than Earth from the Sun, making it hotter. In comparison, Venus receives 90% more light from the Sun than Earth. We do not know the properties of the atmosphere of Gliese 163c but, if we assume that it is a scaled up version of Earth’s atmosphere, then its surface temperature might be around 60°C [140°F]. Most complex life on Earth (plants, animals, and even humans) are not able to survive at temperatures above 50°C [122°F], however, plenty of extremophilic microbial life forms can thrive at those temperatures or higher.

A new study of the Earth’s past climates has revealed that during warming periods the number of species multiplied.
A new study of the Earth’s past climates has revealed that during warming periods the number of species multiplied.
The article spends a lot of time explaining that just because global warming in the past was beneficial for life does not mean that global warming today will be a good thing. Or to put it another way: “Absolutely not! We mustn’t think that! It can’t be! Never!!!! My fingers are in my ears! La-la-la-la-la-la-la-la-la-la!”
And they call this a maximum?

The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.
The Forest Products Laboratory of the U.S. Forest Service has opened a $1.7 million pilot plant for the production of cellulose nanocrystals, which have the potential to be stronger, stiffer, and lighter than Kevlar or carbon fibers.
It appears that the lab has been researching the useful properties of these nanocrystals, which is a good thing. However, I can’t help wondering why they are now building a production plant. Shouldn’t this be left to the private sector? What business is it of the Forest Service to be a producer of this product? It could be that the plant is aimed not at production but at figuring out how to make it affordable and practical, a goal that might make sense for a government agency to pursue. If not, however, it seems inappropriate for a government agency to use taxpayer dollars to run a facility aimed at selling a product to the private sector.
The article, as well as the lab’s webpage, do not make this clear.
