Comment Alternative chat rooms (Score 1) 250

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?

Comment Light gas space cannon? (Score 1) 190

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?

New Food-Growth Product a Bit Hairy 243

MeatBag PussRocket writes "An article from reports, 'A Florida company has developed an all-natural product that it says could revolutionize how food is grown in the US. It's called Smart Grow, but it might be a tough sell. It's inexpensive. It eliminates the need for pesticides, so it's environmentally friendly, but it's human hair. Plant pathologists at the University of Florida have found the mats eliminate weeds better than leading herbicides and can also make plants grow up to 30 percent larger.'"

Comment Quantum Tunneling (Score 2, Informative) 137

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.
