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!”

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.

The head of the Russian space center that built the upper stage that failed on two recent Proton launches has been fired.

The head of the Russian space center that built the upper stage that failed on two recent Proton launches has been fired.

Putin’s action here suggests the Russians are taking these problems seriously. especially with the looming competition from SpaceX. At the same time, the boss doesn’t actually build anything, and firing him won’t fix anything if there aren’t also changes on the factory floor.

“Healthy Ridicule.”

“Healthy ridicule.”

It is healthy for America that the president be criticized and even mocked. Deference to a Dear Leader has no place in a democracy. It’s healthy for race relations, too, that he be judged on his record rather than held to a lower standard in the name of racial progress. When a black politician is treated just like any other politician, that’s genuine progress.

And then there’s this:

Obama’s journalistic supporters live in a bizarre alternate reality in which a politician’s actual words mean nothing. When the president says something foolish and offensive, he didn’t say that. Meanwhile every comment from a Republican can be translated, through a process of free association, to: “We don’t like black people.”

Taranto’s second point above suggests to me that there are a lot of people on the left whose recent behavior is making them ripe targets for some very healthy ridicule.

New Horizons — on its way to Pluto — will take a look at a different Kuiper Belt object in January 2015.

New Horizons — on its way to Pluto — will take a look at a different Kuiper Belt object in January 2015.

The encounter will take place at a range of about 75 million km, a distance somewhat subject to change depending on how the probe makes its course correction. At such a great distance, New Horizons will not be able to discern features on the surface of the KBO, nor will it be able to make spectroscopic observations to try to determine the composition of the surface material.

However, New Horizons will be in an excellent position to look for small, close-in moons around the object. It will also be in a position to observe the object’s phase curve, which is a measure of how the reflectivity of the surface changes as a function of viewing angle. This will reveal a great deal about the fluffiness of the surface material (note – fluffiness is a technical term meaning, roughly, “the opposite of dense”). These two observations cannot be made from Earth, even with the most powerful telescopes available.
