No mention in the article of the strength of the new material. How would this compare to regular concrete?
Not only no mention of the strengths, or the weight of absorption, but also no mention of the huge body of knowledge of cement that the building industry has amassed over time.
There is a cement for every purpose, using formulas worked out over hundreds of years, virtually every aspect of it is well understood.
Who knows about the new stuff?
Who builds the first bridge, or sky scraper that will get heavier (by 2/3rds according to the article) as it ages?
And what about the fossil fuels used to make the cement? Do they remain the same?
People are going nuts looking for CO2 emission sources in all the wrong places. Look at the chart of CO2 emission sources. Soda Ash production (the category that includes cement) is WAY down the list. Microscopic. http://www.epa.gov/climatechange/emissions/co2_human.html
The effort would be better spent building Nuclear generation plants and figuring out what to do with spent nuclear fuels, because a 10% reduction in CO2 emission from fossil fuels would totally swamp any reduction due to cement manufacturing.
Of course the same scare tacticians who see the CO2 boogie man under every bed also won't let us build Nukes. So we cast our hopes in cement, literally and figuratively.

It costs $0.25/hour to run a mid-20" tv. How much do you think it will cost to charge a freaking car every night?
Well if you believe Chevy:
At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for electricity to travel 100 miles, or less than 3 cents per mile.
> Utility officials have already stated that even during peak hours they have the capacity to cope with even several years worth of increases...
Several years worth of increases at what level?
All of these estimates are based on the current level of plug in vehicle growth, which has been approximately ZERO per year.
In 2006 7,667,066 passenger vehicles were produced in JUST the US.
Assuming the Volt and imitators are wildly popular and garners 1 million sales:
1 million vehicles 25KWH per 100 miles (chevy's press release in TFA) 12000 miles per year (epa estimates) 12000 / 100 * 25kwh = 3,000,000,000 KWh / year
Or 3000 Gigawatts per million vehicles per year.
Since the US DOE says we have about 1087 Gigawatt total production capacity this suggest we will be short by 2 thirds.
Actually it strongly suggests they hand waived the electrical generation issues away.
The check the odometer, compared it to the gas pump. End of story.
That is the definition of Miles Per Gallon.
GMs goes on to say in their news release:
"Applying EPA's methodology, GM expects the Volt to consume as little as 25 kilowatt hours per 100 miles in city driving. At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for electricity to travel 100 miles, or less than 3 cents per mile."
However that says nothing about the carbon/emmissions equivalent of Coal fired plants vs gas fire engines. Nor does it address where 25KWH times X million vehicles.
Also glossed over is the fact that the production costs of the vehicle: "the cost of building a Volt will be expensive, about $40,000 per vehicle. "
That's production costs. Crank in a typical profit margin and you are at 60,000 showroom cost.
You are also going to see metered parking lot outlets. (These are already used in places like Fairbanks Alaska for headbolt heaters).
There is no free lunch, and there is no work place recharging stations for 99.9999% of workers. The fact that NetworkBoy found one is 1) a miracle, 2) short lived, 3) bound to be usurped by his boss.
So NetworkBoy will end up paying the full recharge bill and will have to charge at home. Still not so bad.
But, IF this vehicle ever became popular we will have another crisis on our hands. The electrical grid probably can't handle the load, even in off peak hours, let alone in high-demand hours. And while you wait 15 years to get another nuclear power station permitted you will be keeping the coal fired plant up all night.
Just about all coal generation plants are Clean Coal plants these days, but the definition of "clean" keeps changing. The juice has to come from somewhere, and scrubbed coal plants may be cleaner than the exhaust of millions of vehicles, but it is by no means a Free Lunch.
So advocates need to temper their glee with a little reality check until they can hang enough solar panels on their roofs to charge their cars.
People are choosing to buy the tunes they like, (and occasionally the Albums they like), but not the usual trash foisted on them to fill the album.
Music sales are doing well.
Paying 15 bucks for 2 good songs and 9 garbage songs is what is failing.
The DRM issue is is a serious one, just as the GP mentioned. The ability to repossess your music purchases at any time in the future is theft, pure and simple.
Buggy whips were doing well for a hundred years too.
I think its entirely possible the reason for the absence of response is in the first seven words of the original post.
Code quality counts. Its hard enough to write clear and maintainable C code, (once described as a language where your entire code base becomes obsolete when your programmer walks out the door), without having to rewrite huge sections into the format compatible with the rest of the project.
Junk DNA is one of the greatest misnomers in genetics. It basically arose because people didn't understand the purpose of a particular gene, or they found (as in this case) that a sequence was prematurely terminated due to an encoding error, which could only be detected via comparison to another working copy from another source.
This opens up a new field of bug detection: looking for broken code, figuring out what patch is needed and then figuring out what you could do with the repaired gene. This is going to call for vast amounts of computer simulations.
In this case we were led to a solution to the breakage by a similar gene in another species. But there must be millions of broken genes laying about that might re-enable some traits, anything from gills to the ability to smell tyrannosaur breath. (Pedants: Look, its a joke, please don't bother pointing out the time line here, Ok?).
There seems a tendency to assume all "lost things", (genes, knowledge, secrets of the universe, methods of building pyramids, etc) are of immense value, and far superior to knowledge we have today. (Slashdotters will surely have a term for this.) Not everything lost is desirable. This is one example that may well be.
Many species might be expected to genetically re-energize, by natural means, any lost protection in the face of a re-appearing threat. That might take eons. If this discovery leads to a treatment, it will be signal the dawn of genetic dumpster diving on a huge scale.
One need not have reasoning. One need not show ones work.
Correlations are useful all by themselves, even in the absence of reasoning.
Causation need not be present for correlations to be useful. Secondary or tertiary causations need not be known, proven, or even speculated upon.
Yes, failure to investigate causation is the source of superstition. But superstition is generally harmless. Failing to heed correlations can be fatal.
With the successful campaign to free up breathalyser source code how long before this is challenged and the science behind it questioned? Before or after multiple convictions?
Can being at the party and kissing the babe with the razor blade be sufficient to get traces in your saliva?
It seems like this goes way beyond Free, in that this will deliver a working virtual machine, Live CD, or installation CD already with the additional repositories attached, and packages installed.
When it gets enhanced so you can select hardware of interest simply by clicking machine make/model from a list it will be sweeter yet.

Proper behavior is to show a static page saying it can't be found.

Why not TRY it in Firefox and compare results to IE like everybody else is doing?

Not everywhere uses coal when nuclear isn't available. Tons of places use hydroelectric which is comparatively MUCH cleaner than coal.
Tons of places?
Sadly, Hydro rates a distant 4th place, producing less no more than 7% of US power.
See http://www.eia.doe.gov/cneaf/electricity/epa/epat2p2.html for current US electrical capacity by source.

just sayin....
Traits are selected FOR, more than they are selected against. When this amunity was no longer needed it fell into disrepair.
Natural selection expends no energy suppressing traits that are not harmfull, nor maintaining those that offer no advantage.

Sure it does. You just said it does.
You said they correlate.
Therefore, if ice cream sales are increasing you can expect shark attacks to increase.
Because they correlate.
You have forgotten what you set out to prove. Causation need not be present for correlation to be useful.
