Bioethicist At National Institutes of Health: "Why I Hope To Die At 75"
On the other hand, 75 is an arbitrary number. I'm 53, and will match wits with any of you.
OK, but I am not falling for that iocaine trick.
New Data Center Protects Against Solar Storm and Nuclear EMPs
A "Carrington-level" event nowadays would most likely be much less disruptive, as back then all the early radio and spark gap stuff was well under 50 MHz, which is where almost all of the natural noise winds up in the spectrum. Ever notice, for example you can hear your shaver motor on an AM radio but not an FM one. This is not due to AM vs. FM, (well, it is a little) but mostly due to the fact that AM is about 1 MHz and FM is about 100 MHz, well above the "static line" around 50 MHz.
It would take a much stronger signal than back then to cause the same level of disruption. Not saying that can't happen, but modern radio communications are quite a bit more robust than they were back over 100 years ago.
The concern is not so much about the disruption of radio communications, but the power grid. Our society might not survive a massive, long-term (months or even years) blackout (a huge number of transformers might be destroyed all at once by the induced EMF).
Liquid Sponges Extract Hydrogen From Water
You still need very pure water or you poison the process. Where's that water coming from? How do you collect the gaseous hydrogen? You still need to liquify it and all the emrittlement and cryogenic issues are still there.
Even if hydrogen gas is free, it makes no sense as an energy carrier for cars.
They don't collect the gaseous hydrogen in the electrolyzer; they soak it up with a "liquid sponge" ("a recyclable redox mediator (silicotungstic acid) " according to the article's abstract. In principle at least, hydrogen could be stored and transported in this form (a liquid sponge soaked with hydrogen).; the hydrogen can be catalytically released (wrung out of the liquid sponge) when needed. Whether such a system could be built with a practical size, weight, and cost for use in vehicles is another matter.

Geneticists Decry Book On Race and Evolution
In order for a Northern European to evolve fair skin and hair, there has to be something that will kill a human of dark skin and hair. Since people with dark skin can survive in Northern Europe, it is not through evolution.
The "something" doesn't have to kill, just reduce the probability of reproductive success. Vitamin D deficiency fills the bill.
Group Demonstrates 3,000 Km Electric Car Battery
What I'm wondering is why I want to carry around 2 months worth of fuel in my car and be sitting on top of that amount of potential energy in a crash?
Maybe because of the unlikelihood that all of that energy would be released rapidly enough to cause a safety concern?
The Sci-Fi Myth of Robotic Competence
Lin and Sofge advocate that the programmers should use strict utilitarian philosophy when deciding what to hit. I don't think that is going to fly, either from a legal or a sales perspective; the least damaging choice is just to try to stop the vehicle even if there is no time, rather than trying to "select" a crash for the least possible damage.
I agree--the results of collisions are simply too unpredictable. The idea of "knowing" the outcomes and choosing the one that leads to the fewest deaths (greatest utility) is preposterous. If a collision is unavoidable, simply remove as much kinetic energy as possible in order to minimize damage to the vehicle and its occupants.
As NASA Seeks Next Mission, Russia Holds the Trump Card
So much of the budget is off-limits (social security and medicare) that the only areas left vulnerable to cutting are things like NASA.
The USA has locked itself into forced spending in some areas and it's squeezing other areas.
We could double NASA's budget and pay for it with a 3% cut to the military.

Talking To the Public: the Biggest Enemy To Reducing Greenhouse Emissions
And by easily I mean it has to be as cheap and effective as the dirtier power sources like coal and oil. Otherwise countries will never go towards it as it's too much of a hassle.
The problem with this reasoning is that coal and oil are only cheap if you don't count the cost of building seawalls, moving people inland, loss of arable land, and so forth. There will be longer growing seasons, open Arctic sea lanes, and other positive effects as well, but the consensus is that the net effect will be negative. Factor that in and wind and solar become cost competitive with fossil fuels.
The Koch Brothers Attack On Solar Energy
Solar panel creation uses many toxic products, chemicals and dangerous gases, including Sulfur Hexaflouride, the MOST POTENT GREENHOUSE GAS... Is it really about the planet, or is it about money?
From Wikipedia - "According to the Intergovernmental Panel on Climate Change, SF6 is the most potent greenhouse gas that it has evaluated, with a global warming potential of 23,900 times that of CO2 when compared over a 100-year period."
2002 was the last year I could find a quick worldwide sales number for SF6, 5096 metric tons. Using your factor of 23,900 and rounding up, that's the equivalent of 122 million tons of CO2 assuming every molecule of SF6 was dumped directly into the atmosphere. By comparison, in 2012, an estimated 9700 million tons of CO2 were emitted. Of course, only about 7% of SF6 production is used in semiconductor manufacturing, and only a fraction of that is solar cell production and of that fraction not all is released into the atmosphere. Cradle-to-grave estimates for all greenhouse gas emissions in grams of CO2 equivalent per kWh came in at 1001 for coal, 500 for natural gas, and 45 for solar cells.
Capture and sequestration of CO2 from burning coal would have large capital costs and increase coal usage by about 30%, putting the cost of electricity from coal right in the same ballpark as unsubsidized wind and solar.
Please do a little research and thought before you shout "ZOMG SF6 MOST POTENT GREENHOUSE GAS!"
Pollution In China Could Be Driving Freak Weather In US
Americans constitute 5% of the worlds population, yet we consume 24% of its energy.
Please stop using this bogus comparison to imply that Americans use more than "their share" of the world's energy. The correct comparison is between inputs and outputs. The USA produces nearly 20% of the world's GDP. If your 24% is correct, we have room for improvements in energy efficiency, but we're not nearly the energy gluttons that you're suggesting. The low ratio of population to energy use is largely due to our high productivity.
Climate Scientist: Climate Engineering Might Be the Answer To Warming
Shesh, nope. First, what tax subsidies are you talking about? There is no way Coal is subsidized, nor is oil and gas.
Do a little research. Here's a starting point.
It's going to be cheaper to make electricity by natural gas for a LONG time, especially over solar.
That depends on how bad the fracking earthquakes get.

GM Names Names, Suspends Two Engineers Over Ignition-Switch Safety
I have long held the belief that software can be life critical at times and software engineers should be held to the same professionalism as any other form of engineering.
It is a matter of fact, not belief, that software can be life critical. For the majority of software, though, cost and time-to-market considerations far outweigh coding to the highest professional standard. "Good enough" wins.
GM Names Names, Suspends Two Engineers Over Ignition-Switch Safety
In most places "Software Engineers" meet no accreditation requirements, have no requirement to belong to any society which regulates ethics, experience or training.
I've worked with real engineers, ethics was more important than their education.
There is no requirement to belong, but at least there is a society that promulgates ethics.
