Are you suggesting a privatized National Weather Service and toll bridges would be better? If so, I have a nice bear-ridden town in New Hampshire you might like to move to.
Regulations are exactly how you deal with negative externalities.The EPA makes corporations pay for reducing pollution and cleanup. Why do you think corporations target EPA so much? Because EPA costs them money. Never hear any corporations whining about that free taxpayer-funded geological data coming out of USGS
Oh, we have lots of those! There are some drugs that we use to treat high blood pressure work by causing vasodilation.
What's really interesting about this new drug is:
"...iloprost is not only a vasodilator but also reduces oxidative stress, suggesting this dual mechanism of action could help explain its impressive potential as a frostbite treatment."
It not only dilates blood vessels, it also directly treats reperfusion injury, which is really neat.
