While it raises concerns, a few things to note:
It is one primary study that has just been released and is undergoing further peer-review. Results need to be replicated by other researchers with better controls and varied methods. Why was the control group (92) so much smaller than the cannabis group (982)? This is unusual for this type of study.
Possible selection bias, this was heavy current use of cannabis by people who managed to be diagnosed with "cannabis use disorder".
Reduced blood flow is a pharmacological effect of cannabinoids. They can constrict blood vessels. The researcher may simply be observing something that for the most part wears off with abstinence (it can take days/weeks for the heaviest of users to clear the system).
Other research has suggested cannabinoids may help treat and prevent Alzheimer's.
Great, China and the rest of the world are catching up and will soon surpass us in space technology and capability and what do we do? Reduce NASA's relatively tiny 0.5% of the Federal budget even more.
Why down vote this? The core cooling is one of the leading theories on how Mars lost it's magnetic field. Without a magnetic field, radiation and energized particles from the sun and deep space were able to blast most of the atmosphere away.
So no point in taking the console on vacation if you have no internet, also if you're internet is down for more than 24hrs you're screwed. The 10 person limit on playing your own games is laughable. No thanks M$, I'd would actually like to control the things I own.
I've played fps's, including the Unreal Tournament series, for years using a keyboard and mouse. I love the responsiveness of the aiming and the ability to put the crosshair exactly wherever I need to and as quickly as I need to. I gave this a try using a keyboard and mouse for UT3 on the PS3 and was greatly disappointed. The mouse was not nearly responsive enough. There seemed to be many frames of lag between moving the mouse and seeing the result on screen. It was like aiming with a wet noodle. I've tried a few different mice and settings to no avail. At least with the PC there was usually some work around for this situation, such as turning down max pre-rendered frames to 1 or 0. Unless this issue is fixed I would honestly rather use a gamepad for FPS's on the PS3. I believe this is part of the reason the keyboard + mouse controls never caught on for the PS3.
I think some comments were left out:
"Upon investigation, we were [not at all] stunned to find that the formula [if (bars=2) then DisplayBars(4)] we use to calculate how many bars of signal strength to display is totally wrong [and unethical since it unfairly makes our product seem as if it has better reception than the others]"
My concern is not so much for known or theorized particles being created, it is for the unknown particles that may be created. The potential discovery of previously unknown particles is part of the purpose of this experiment. I still believe the probability is low that any harm will come from this experiment...at least not on the global scale, but how low is low enough when the potential to destroy everything we are could exist.
These collisions have likely occurred on earth for a long time but never anywhere near the density which they will in the LHC. The natural collisions are spread out over a much larger area and much longer time. Also with natural collisions only one particle is moving at high velocity which might cause any harmful particle or black hole to move through the earth very quickly. In the LHC two particles of about the same velocity collide. This could cause any potentially harmful particles to linger by some or all of the momentum being canceled by the collision. The natural bombardment of cosmic rays into the Earth cannot prove the safety of so many of these collisions in the same place at nearly the
I agree the prefix should be changed since kilo as been established for years to mean 1000, mega 1000000, etc. Apparently there was a standard established in 1998 for a binary kilo called the kibi (kilobinary)
covered here.
Maybe they should have used something more distinct like the Engelbyte (EB) after computing pioneer Douglas Engelbart (60's inventor of the mouse, windows and more);)
"This would be bad. If you where to make 1K = 1000 bytes you would have a remainder when dealing with a word of 32 or 64 bits for instance. The fact that our word sizes are powers of 2 means that our larger unit size has to be powers of 2."
More specifically why would this be bad? Why does a larger unit have to be a power of 2? I am a C++ programmer and have never had much use of a 1024 unit of measurement. If a 1024 based unit of measure is required for some reason it would be very easy for a computer to calculate and convert to base 10. Anyway, when the os reports the size of a drive, memory, or just about anything else it is usually reported as bytes in a long integer. The most convenient sized chunk be it 1024, 1000, 8357, or any random number would depend on the situation.
Hydrogen needs to react with plenty of oxygen to explode. There won't be nearly enough oxygen getting to the hydrogen molecules to cause much of an explosion. A canister of gun powder would be more explosive since oxygen is included in the mixture.
If the world fuel "economy" switches to hydrogen, what happens to the countries which sole income is provided by oil and fossil fuels?
The same thing that will happen when their resources are depleted. They need to change with the times. We shouldn't let a foreign country's lack of progress stand in the way of ours.
Hydrogen power is an amazing thing, but it'd be something like suddenly replacing the staple foods in the world with chemical products
There will be nothing sudden about it. Fuel cells were invented decades ago. We're only beggining to see commercial models now. Our economy will have time to adjust. Granted, it might not be a smooth transition.
"I think a lot of people are bringing their computer to the home theater in the family or media room and converging it that way."
Most people use their computer for business and/or games. For business, concentration is especially important. A family room is an unlikely place in a home to concentrate effectively.
While the computer would be in use in the family room, other family members could not use their main entertainment center. In addition, why tie up a machine capable of so many other things by watching a movie when TVs are designed for that specific purpose?
What will we do when there is more copper, gold, iron, coal, etc. in our landfills then there is in the ground, as the temperature keeps rising higher and higher, when there are less than 100 billion trees left in the whole world? Are we to pin all our hopes on a few scientists enabeling us to mine asteroids and distant planets and colonizing space?
Science gave us the ability to recycle. Recycling is vital to any long term space mission. It is likely more recycling technologies will be developed from the space program.
Technology only trades one problem for another. Because in our society of specialists you do not see people mining coal and transporting to power stations to burn for your electricity, it is easy to forget this.
Alternative power sources are also vital to space missions. Solar Energy was pioneered by NASA.
Social improvements can make life more enjoyable for humanity than technological advancements under capitalism, that the people in affluent nations can only enjoy. Would you want to live in a brutal dictatorship with high technology, where the technology would be used to make telescreens to spy on you, or a more human society that is less advanced?
I would rather live in a society where I won't die of a broken limb from a simple infection. I would rather live in a society where dictatorship is obsolete. Technology provides communication that allows the masses, the true power in this world, to unite against any such form of government. We've existed for millions of years without science and got nowhere, socially or otherwise. It was technology that changed us from club-swinging apes to who we are today. The space program is a driving force of technology.

The theory still implies something was there before...otherwise what were these quantum fluctuations "in" ?
"... these gadgets are really destroying their ability to learn." Or maybe kids just learn differently with these "gadgets".

Microsoft has become excessively greedy, even for them.

The figures only include people who actually paid income tax.
Actually it's less than $9 per year for an average income American ( http://nasacost.com/ ).
This article is misleading. Most sites will lock you out after so many failed attempts.

How about they just uncheck 'accept cookies' if they don't want them?
This is just one more reason we need a massive effort to develop Thorium reactors. It can't meltdown. http://en.wikipedia.org/wiki/Thorium
