Does it count as climate change-related when these fires are starting due to human activity? It seems part of the problem is that one fire starts, either by accident or on purpose, and then several more pop up as fire bugs start lighting fires all over (as was the case in San Diego). FD resources get strained and it just takes longer to put them out because efforts are spread thin. My guess is that large fires would be just as infrequent if you removed us from the equation.
>>Mildly interesting to see what's happened to Apple and Creative's stock since the two announcements (looks like Apple's lost ~4% & Creative ~2.5%).
Sorry to be a bit OT, but this statement isn't necessarily correct.
Actually the drops in stock price is more likely related to the overall drops in the stock market. The ratios of losers to winners this week was over 4:1 or 5:1. Dow-Jones is down about 500 points in the last week and a half on a number of outside factors, so it's not unlikely that both Creative's and Apple's losses are part of greater market downturn in the last several days.

Warm-blooded Fish?
·
· Score: 3, Informative
These sharks, along with makos, tunas and thresher sharks have countercurrent heat exchange vasculature that allows them to maintain elevated body temperatures, so this finding isn't necessarily new. The ability to maintain elevated temperatures often allow these animals to make deep foraging dives into cold water, or, in the case of the salmon shark, live in colder waters. The consequence of cold muscles is that you also move slowly (think of how your hands feel when you forget to wear gloves when it's really cold out). It's also thought that by maintaining elevated brain temperatures these fish are better at processing visual information, among other things (who knows - foraging behaviors?).

This wouldn't be so much of a problem if the scientists simply castrated the thing before the experiment. It would have at least eliminated the shrinkage factor in that cold ocean water.
The university where I work already incorporates this tactic, and it works quite well. The only way to get your computer back on the network is to prove you've installed virus software + firewall, and have completely rid your machine of the malicious software. It really gets users to shape-up quick. They also run a daily scan of the network for certain open ports and vulnerabilities that are commonly used by worms. "Punishment" is still the same - fix it or remain cut off.
Rent a DVD for $0.99, buy one for $15-20, or spend $12 on a pass to watch junk in the theater? Is it really that hard to figure out why less and less people are watching movies? Theater passes cost less than $5 five to ten years ago, so how they can justify more than doubling the cost in such a short period of time is beyond me.
Funny thing about bats in the kitchen. At work I found a small tupperware of bat heads in the "biological samples only" refrigerator. Must belong to some other lab that use our facilities. Either way, I'd have to say that's the most random thing I've come across yet in my time there.
PS: Mod -1 off topic. I just thought I'd share something random from my otherwise uneventful job.
For the most part you probably would have been ok. The chain would have ruined the data, but the MR tech would have caught that during setup. At worst the metal could heat up and burn you (no joke), though it doesn't happen most times.
Speaking of MRIs gone wild, so many women who come in for (research) scans make some joke about how the magnet might be so strong it'll rip their bras off.
Certainly. It just so happens that the engineers who actually develop MRI equipment used linux. I didn't RTA but no matter. The GE scanners we have in our research center use a special version of Linux: GEHC Linux (GE Health Care) running on the console. At least as of a few years ago Varian scanners were running on Solaris. Take it for what it's worth, but at least in GE's case, it's much easier to take a FOSS OS and tweak it to do exactly as they need it to make sure it will run to certain specs.
Well, if you've ever spent time considering why more expensive cuts of meats are just that - expensive, you'll realize it's typically not just because it's more tender. Most of that oh-so-good flavor comes from a good marbling of the meat, which is none other than fat. Try a tri-tip versus a good top sirloin (tri-tip being relatively lean, and sirloin much more marbled).
Also, if it's an MRI made by General Electric (the current Signa Excite branded 1.5 and 3.0T series especially), you don't have to worry much anyway... since most of them are defective heaps!
Heh. It's the nature of MRI to be extremely sensitive. Considering you're measuring the bulk magnetization of a very small number of protons, it's amazing the technology even works! So far I've been pretty happy with the performance of the Excite 3T, though it doesn't mean we didn't have any problems getting there. One thing for sure, though, it beats the pants off the Varian scanners I've ever used, and by "used" i mean it very loosely. It's one thing to use a Varian, and another thing to use it and get even halfway decent results. As far as I'm concerned, GE may be as good as it gets.
Tinfoil would help because any metal will cause magnetic field (and signal) inhomogineities, which manifest themselves as pretty big artifacts in the image. MRI is dependent on both magnetism and RF.
It's one thing actually figuring out how to solve a "novel" math problem, and it's another to say you've memorized all the tricks and shortcuts to get the right answer on a test without doing any actually solving. Though I suppose I'm wrong in the first place to equiate intelligence to IQ (but where does one draw the line?). However, knowing about the Myers-Briggs Type Indicator (MBTI) will tell you that people with the iNtuition (N) typically do better on tests than those with the Sensing (S). Either way, it's neither here nor there.
... and anyone who thinks SAT scores are indicators of intelligence clearly knows NOTHING about the test. Even minimal amounts of studying for the test can raise your score considerably.
First of all, this should not be that big a deal. His biggest problem is the way in which he's asking.
has requested raw data and personal financial information on three scientists
Secrecy only makes the research appear to be more questionable. The personal financial information is nothing more than conflict of interest information, trying to determine if they were paid by any special interest groups or not.
