Teaching needs an ecosystem that supports evidence-based practice. It will need better systems to disseminate the results of research more widely, but also a better understanding of research, so that teachers can be critical consumers of evidence.

The value of a scientific publication goes beyond this simple benefit, of all relevant information appearing, unambiguously, in one place. It's also a way to communicate your ideas to your scientific peers, and invite them to express an informed view.

If a scientist sidesteps their scientific peers, and chooses to take an apparently changeable, frightening and technical scientific case directly to the public, then that is a deliberate decision, and one that can't realistically go unnoticed.

I've never cared for the idea of a career path, or where a film might 'take me.' My love is for acting not money, so I only take on roles that I find challenging, in stories I find interesting.

There is no tax policy that better describes how out of touch America's liberals are with the rest of the country than the estate tax. According to the Left, government seizure of a large share of the wealth of an American taxpayer is a moral imperative that serves social justice. Most Americans disagree, big time.

So we in Congress have a very clear choice. We can take largely symbolic action and sit back and fiddle while Americans burn more gasoline. Or we can pass concrete, effective legislation that will save consumers money while significantly reducing U.S. oil consumption.
