Pretty much all of those advantages used to tout BTC are better achieved through a specie currency like gold.

I've been using a skype text conference as an invite-only chat room for some of my online friends. Why not IRC? Because skype keeps track of all history and logs so you don't have to idle in the room 24/7 to see what people said when you were away. I have found nothing as convenient and suitable to our purposes. Now, I'm starting to worry about the future. Does anyone have a suggestion for a different system?

Their existing high speed rail lines are racking up serious debt. This plan to expand it is difficult to believe.

Googling the researcher's name and his institution only brings up this story. Looks like you someone successfully trolled slashdot.

One thing that I never got was how an volcano in Antartica actively emitting hydrogen chlorine cannot contribute to stratospheric chlorine. Anywhere else, HCl would just stick to a water droplet and rain down, but we are talking about the most arid continent on earth, with very little precipitation.

Wrong. The specific technology in question: http://en.wikipedia.org/wiki/Backscatter_X-ray

Climate change?

The cartridge is called .45 ACP, Automatic Colt Pistol. It is understood by gun people that an automatic pistol is not full, but semi-automatic.

Sounds like the first step towards Asimov's future of being educated by tape, because some people's brain patterns are suited to different professions.

They had to pay people to use their search engine?

Could someone tell me if there is anything wrong with using a light gas cannon as the first two stages of a rocket as John Hunter proposes? Is the amount of propellant needed to fire the gun more than would be required by a traditional kerosene/LOX motor? It sounds to me like a space cannon would be an inexpensive way to launch non-living cargo mass. Has nobody invested in this sort of project because the space gun people all went to work for Saddam Hussein?

It is not new at all that quantum tunneling is an important mechanism in the electron transport chain. The iron-sulfur centers are optimally positioned to optimize the tunneling rate of electrons between them. They knew about this several years ago, when I learned this in an undergrad biophysics class.

The FDA is an affront to medical freedom in the US. Like all regulatory agencies, it has formed a cartel with the businesses it was implemented to regulate. We are left with mainstream medical knowledge subject to lobbyists. The FDA pushes flawed studies as irrefutable science, dangerous drugs, and a diet not suited to humans.

Private, voluntary certification companies like Underwriters Laboratories have an incentive to be honest, because they will go out of business if discredited. Likewise, pharmaceutical companies need the certification of an outside party to gain and keep the trust of consumers. The FDA should not be that party. Unlike the UL, it is a government bureaucracy that does not need to maintain a good reputation to stay in power.
