"All a surgeon has to do is move the pen's tip along the cut, strengthening and sealing the weld with a solder of water-soluble protein."
It looks a lot like very controlled cooking and I suspect the protein used to connect the tissue denatures in the process. It's not welding, it's hot-melt glue.
Halon works by giving up chlorine and bromine radicals which bind to and inhibit the free radicals (H, OH and O) involved in the chemical mechanisms of the flame. It doesn't react with molecular oxygen in the air.

Lead is a neurotoxin; children exposed to lead are at risk of developmental delays, reduced IQ, learning disabilities, hearing loss, reduced height and hyperactivity. Levels above 10 mcg/dL (about 100 ppb) are considered to be a health risk to children. Adults are at risk of anemia, nervous system dysfunction, kidney problems, hypertension, decreased fertility, and increased level of miscarriages.
It used to be that the biggest source of environmental lead was automobile exhaust, followed by lead paint. In the late 1970's 14.9 million children in the US had elevated blood lead levels. This figure declined to about 300,000 in the US CDC's 99-00 survey. Banning lead paint in 1978 and leaded gasoline's phase out starting in 1975 removed the sources of exposure.
In adults, levels above 24 mcg/dL are considered elevated and mostly come from workplace exposures, such as demolition, recycling and manufacturing. The number of adults with elevated blood lead levels has also been declining.
The problem with adult exposure is that without proper industrial hygiene, the lead comes home with them, providing a route of exposure to their children. 2-3% of children with elevated blood lead levels are exposed in this way.
Lead in manufacturing is an expense since exposure has to be managed. But, if you don't control it at the source, then you have to try and manage it in the waste stream which is much more expensive and difficult. Given the population density and the emphasis on recycling in the EU, lead exposure through this route is a decreasingly acceptable risk to the population.
P.S. The EU is the largest economy in the world so you tell your directors that you don't need that market anymore!
The propellant mixture in each SRB motor consists of an ammonium perchlorate (oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide (a catalyst, 0.4 percent), a polymer (a binder that holds the mixture together, 12.04 percent), and an epoxy curing agent (1.96 percent).
The significant difference from thermite and the Hindenberg paint is the ammonium perchlorate oxidizer, a much stronger oxidizing agent than the iron oxide. BTW, a perchlorate production plant in Utah was destroyed in an explosion in 1988 when a welding torch ignited more than 100,000 lbs of the stuff.
Furthermore, the substance used to coat the cotton skin -- a process known as "doping" which makes the fabric taut and more durable -- was extremely flammable. A combination of iron oxide, cellulose acetate and aluminum powder, "the total mixture might well serve as a respectable rocket propellant," Van Vorst said.
Iron oxide and aluminum powder are commonly referred to as thermite and are used for producing molten iron at temperatures well in excess of aluminum's 660 C melting point. However, there is a rebuttal to this argument which indicates that the paint lacked the requisite proportions for the thermite reaction.
Agree with parent, the intro screen is hideous and not obvious. The site fails in Firefox on Win32 and Linux platforms. Curioulsy, it works in konqueror 3.14, if you're running KDE.
From the Gulf of Maine Aquarium website: "Jason Jr. is a remote-controlled underwater robot that explored the interior of the sunken Titanic on Ballard's second expedition. It was operated by a remote control "joy stick" to probe inside the Titanic to take still and video images. It went into the grand ballroom, captain's stateroom, and down several flights of stairs. It was tethered to Alvin via a long cable."
Therefore, it was not autonomous.
Neil Postman's pointless drivel drives me nuts and I'm not the only one.
"It is hard to square Postman's appeals to authority on behalf of an insipid deism with the definition of the Enlightenment with which he begins his book: ''A philosophical movement of the 18th century focusing on the criticism of previously accepted doctrines and institutions from the point of view of rationalism.'' Invoking Voltaire, Postman all too often resembles Dr. Pangloss."

Oh for crying out loud. This is what passes for news at lame wannabe Tucker Carlson's attempt to mimic Politico? The guidance letter was published in October 2010 and you can read it here: http://www2.ed.gov/about/offices/list/ocr/letters/colleague-201010.html

Still very cool.

It's Dr. Evil, I didn't spend six years in Evil Medical School to be called "mister," thank you very much.
Get the quote right: "Attempted murder, now honestly, what is that? Do they give a Nobel Prize for attempted chemistry?"

OK, I'll feed the troll.
