Higher levels of carbon in the ocean are causing oysters to grow slower, and their predators — such as blue crabs — to grow faster
versus
Under conditions with lower levels of carbon, two mud crabs polished off 20 oysters in six hours. But in the aquariums with higher levels of carbon, the mud crabs seemed confused. They went over to the oysters, but they didn’t eat as many — sometimes fewer than half of what other crabs ate under normal conditions.
Voyager has no need for power to continue its journey; running out of power will have no effect on its velocity.
You're forgetting drag. Just like flying through air, flying through parts of the solar system results in drag from dust. The dust density is expected to increase when the probe reaches the inner Oort cloud, unless Voyager 1's path has angled enough above the ecliptic that it manages to miss it (I thought 35 degrees was high enough, my colleague disagrees.) If dust density increases, the drag will provide a small but continuous slowing effect. Once past the inner Oort cloud dust density will likely decrease, though no one I've worked with has a great guess of the dust density in the outer Oort cloud. It will still be non-zero though, and Voyager can't avoid the outer Oort. Added to the small but still present force of gravity from the sun (which is what keeps the Oort objects from drifting away), you have continuous drag on the craft.
We can't calculate the effect of that drag without knowing the dust density, and our estimates of the size of the Oort clouds are still rough (on the order of +-100AU last paper I read), which is why that NASA paper estimated crossing the outer edge of the Oort cloud in a range from 14K to 28K years. 14K if the Oort cloud is small and fairly dust-free, twice that long if our worst-case estimates of the density and size are correct.
the linked stories don't mention how big a change in radiation was experienced. Are we talking 10%, or a factor of 10?
Yes they did, from TFA:
"Anomalous cosmic rays, which are cosmic rays trapped in the outer heliosphere, all but vanished, dropping to less than 1 percent of previous amounts."
and also
"galactic cosmic rays – cosmic radiation from outside of the solar system – spiked to levels not seen since Voyager's launch, with intensities as much as twice previous levels"
Its already pasted the ort cloud
No, according to NASA's Voyager project page, Voyager 1 won't escape the Oort cloud (really the outer Oort cloud) for another 14,000 - 28,000 years. (Probably due to running out of power in the next 10 to 15 years.)
If your pages are not connected via links to any extern sites, then by definitionem, they are not part of the World Wide Web.
Do search engines count? Two of my sites are only linked from Google - a Google search for "link:sitename.com" yields no results, but Googling "sitename", "sitename.com" or some of the other variations returns all the pages. So they are reachable by people who know about them, and also to people who don't know the URL or IP address but know what to search for, but the site fail the "19 clicks" test unless someone has linked to a Google search that returns this site in the results. (Hasn't happened as far as I can tell.)
And how do you determine the age of some random rocky mass that you can't even image?
According to the BBC article, they simply guessed the age. The sub-brown dwarf or rogue planet seems to be travelling with a group of stars, and they've estimated the age of the stars to be 50 - 120 million years. It's a form of extra-solar profiling: That thing over there isn't a star, but it's hanging out with those other stars, so it must the same age as them. (Which is apparently OK to do for stars, but not people?)
Or perhaps you've heard the saying about 75% of people think they're above average? I'm sure there's a real study behind that, somewhere, but it strikes a chord for all of us, either way.
It's easy for most of us to be above average, if the people at the bottom are far from the mean. Take five students writing a test: four of them score 50/100, one falls asleep and scores 0/100. The average score is therefore 40/100, and so 80% of the students scored above average. When you were thinking up the saying, you must have meant the mean not the average?
Getting Windows 7 from a shop is surprisingly expensive
He didn't even look. NewEgg is selling it for $99. A 30 day WoW subscription is listed on the Blizzard store for $15. So your OS costs less than 7 months of playing just one of the games you listed - tell me again what's expensive?
by making constant but weak measurements of a quantum system, physicists have managed to probe a delicate quantum state without destroying it – the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it. The result should make it easier to handle systems such as quantum computers that exploit the exotic properties of the quantum world.
So, hot on the heals of a Slashdot story about Australia moving to fibre so they can push VOIP, we now get a story that states that they want to:
force all Australian telcos and internet service providers to store the online data of all Australians for up to two years
Yeah, don't worry - they're not related though. Really, we just think VOIP will improve everyone's lives.
