…in the 21st century we need teachers who teach math and science to have expertise in math and science. So there needs to be an upgrade there, and refocus on how much we value those teachers. As you know, in this country, we don’t pay our teachers all that well. We need to rethink that.
The problem isn’t that we don’t pay teachers well, at least on average. The problem is that we don’t pay the valuable ones enough, and we pay the worthless ones far too much, thanks to the unions. We need to be able to adequately compensate the teachers who have actual useful knowledge to impart, and get rid of the ones who don’t. This would all start by eliminating the worthless, or to be more accurate, negative-value, “education” major.
Such is the state of Obama’s America that a dismaying number of people think that banning ATMs would be good for the economy. It’s the new Luddism, led by the Ignoramus-in-Chief.
Optical imaging labels can report on the molecular workings of tissues and cells in the body. Fluorescent protein tags that emit visible or infrared light are now common tools for studying cell biology in test tubes. But getting such light in and out of the body is difficult because light diffuses as it passes through biological tissues. Living lasers, if they’re made into practical systems, have the potential to change that. One can imagine having a hybrid living-nonliving medical implant under the skin that would beam out a stream of information about biomarkers in the blood, for example.
I’ve commented in the past that I’m much more selective about whom I friend on Facebook than a lot of people seem to be. I will never respond to a friend request from someone who I don’t know, in the sense of having met them either on line or in meatspace, with the exception of those who actually introduce themselves and explain why they want me to friend them. This is just one reason why.

More bipartisan stupidity (or crony capitalism, take your pick): the hidden costs of the ethanol subsidy. If you wonder why food prices are going up, this is one of the big factors.
