Thanks for the second link. I've read Li's and Yin's article and have posted about it further up in this thread but the Sciencenews bit is an easier read than a paper from an academic journal. Btw here is the link to the article: http://www.sustainlv.org/wp-content/uploads/Mercury-from-Broken-CFLs.pdf
If you clean up the broken CFL immediately and you air out the room properly, there is no real danger. Less than 0.1 mg of mercury should be released. Even less if you break an old CFL. Source: http://www.sustainlv.org/wp-content/uploads/Mercury-from-Broken-CFLs.pdf specifically page 4 and figure 2
Some mercury will get into the air, especially over long time periods. However, studies show that the level of mercury released especially if the CFL has been used for a long time before it is discarded, is low. Notwithstanding, it is always a good idea to recycle CFLs. Lots of stores take them back, like Lowe's or Home Depot.

Overvoltages at the point of connection are not an issue if the inverter is at least somewhat recent and has a minimum of intelligence built in. Nowadays inverters measure the voltage and use reactive power to enable the injection of real power without causing overvoltages.
Voltage control with reactive power - In order to keep line voltage constant, SMA inverters supply lagging or leading reactive power to the grid. The grid operator specifies whether the reactive power value is fixed or dynamic. The SMA Power Plant Controller is used to analyze and manage the process. The reactive power, or displacement factor, can also be controlled along a characteristic curve in relation to the supplied active power, the line voltage or an absolute value.
Very little of the contained mercury is actually released since most is bound to the tube. Modern CFLs contain often less than 1 mg of mercury. It takes weeks to release a sizable amount. Nobody will wait that long to clean up a broken CFL.
2) Stop prescribing antibiotics in novel classes for routine things like ear infections and sinus infections. Studies show that most of those will clear up on their own without antibiotic treatment, but nobody wants to be the guy who feels miserable but doesn't get a Z-Pak or some fluroquinolones as treatment.
Recurring sinus and ear infections can lead to permanent hearing loss. Source: http://www.asha.org/public/hearing/disorders/causes.htm That's actually a good example when the usage of antibiotics is appropriate. Not for the first infection or for a mild one. However, a grandmother of mine lost her hearing after an ear-infection on one side which hampered her for the rest of her life. That infection occurred in the time before antibiotics were invented.
Handguns wreak havoc on a suppressor. Look at Iraq. You cannot win a war with a handgun but a sizable portion of the population will make life living hell for any kind of government if the government decide to play against the rules.
Batteries are expensive but just having enough power during the day to recharge and keep at least some level of refrigeration would be nice. In Japan it is mandatory for inverters to provide a power outlet for emergencies.
SMA Solar Technology AG (ETR:S92) will begin limited shipments of the transformerless Sunny Boy 3000/4000/5000TL-US-22 inverter series for 3 to 5 kiloWatt rated AC power PV systems in 4Q12. The TL-US series has added a unique Emergency Power Supply feature providing daytime power to a dedicated power socket in the event of a grid power outage. The power socket is isolated from the grid during the outage and supplies up to 12 Amps so long as the PV system is generating. Grid tied inverters without battery storage support are supposed to shutdown during grid power outages to prevent islanding. SMA developed the feature in accordance with solar inverter specifications required to enter the Japanese market after the Fukushima Daiichi nuclear disaster.
The system you probably saw is based on a Wacom digitizer added to a normal capacitive touchscreen. So the stylus is not using the touchscreen but a Wacom digitizer while switching of the touchscreen gesture recognition while being in use. No need to ape a human finger and thus more precise and smaller.
There are also bugfixes available in newer versions. Don't forget about that.
Stock Gingerbread 2.3.7 ran flawlessly on my mytouch 4G slide (aka HTC Doubleshot). However, the unsupported Cyanogenmod 9.0/1 based on IceCreamSandwich 4.0 both had huge problems with wifi - WPA Enterprise not remembering credentials and the sleep mode during screen-off disconnecting my phone from my wifi network at home. Very annoying especially with a limited data plan. An alpha from the XDA forums for Cyanogenmod 10 which means Jelly Bean 4.1 fixed these problems completely. Now my phone is stable. On an alpha. Granted, I only encountered problems with an unsupported version but other people might not be so lucky. They could be stuck with a stock ICS that does not work with WPA Enterprise without the possibility to upgrade to Jelly Bean. There are open bug reports about WPA Enterprise not working on ICS.
I have to admit that I'm just back to the previous level of functionality compared to Gingerbread but I also got a better GMail App with Jelly Bean and a smoother UI. Not essential but still nice.
Persistent cannabis use was associated with neuropsychological decline broadly across domains of functioning, even after controlling for years of education. Informants also reported noticing more cognitive problems for persistent cannabis users. Impairment was concentrated among adolescent-onset cannabis users, with more persistent use associated with greater decline. Further, cessation of cannabis use did not fully restore neuropsychological functioning among adolescent-onset cannabis users. Findings are suggestive of a neurotoxic effect of cannabis on the adolescent brain and highlight the importance of prevention and policy efforts targeting adolescents.
How about the Netherlands? That should make for a nice location for such a study with pot being legal over there. Btw over 1000 participants.

The French have a great tradition of comic books together with the Belgian school which brought us masterpieces like Tintin. Being a son to a German intellectual, American comics were a no-no and I grew up with the European comics. When I was older and in high school I discovered an interesting series of comic books in the math section of my father's book shelves that I had not seen before which are also from France.
The comics are done by the French scientist Jean Pierre Petit. The books are available for free as PDFs and have been translated to various languages. Most of them are more concerned with Physics but the first link will bring you immediately to the one I found and enjoyed. It is about topology and, if I recall correctly, starts out on a weirdly shaped planet which resembles a Moebius strip.

That is correct, however, the era of cheap energy is ending and along comes the merit order effect. The last quantity of energy that fulfills the worlds need will be more important to the price than the first quantity. If oil prices continue to rise, other sources of energy will follow, since oil is the highest value source of energy. It is highest value because of being ease of storage, ease of trade, and high density.
Who in their right mind would sell energy for cheap if the market is willing to pay much more?

But a vasectomy is pretty much permanent. Don't you think that a temporal prevention of pregnancy also warrants some merit?

But you are saying all laws are?

Why would it be considered a drawback? There is hardly any maintenance associated with owning solar panels.
