Manufacturing scientific mystery

While I thoroughly enjoy questioning assumptions and engaging in conversations at the edge of scientific discovery, the quality of programming on supposedly reputable TV channels is terribly sad nowadays.
 
For example, the History Channel has the series, "UFO Hunters" where, based on the episode I watched, they assume everything is a mysterious unidentified object if they can't explain it clearly within a few moments, with little substantial research. I base this observation on a case where a man took a bunch of video of lights descending, and they plotted out where he was located and the direction he was facing in the various videos. They showed the following map with the location of major airports and discussed the one sight line to the west-southwest where there were no airports located. Their conclusion was that the objects were "unidentified" because there were no airports in the direction which the man saw the lights.

Problem #1 -- their standards for identifying an object or declaring it "unidentified" are very low. The very reason the objects were "unidentified" in this case was due to their lack of effort in identifying them.
 
Problem #2 -- 30 seconds of searching online would have revealed that there are no less than 3 airports in that general direction: Westchester County Airport, Teterboro Airport, and Caldwell Wright Airport.
 
There is certainly plenty of mystery in the world around us. Too bad there's not more time dedicated to exploring the real mysteries instead of the manufactured ones.

Side note: I am perfectly willing to believe in extraterrestrial life -- in fact, it seems statistically likely that we're not the only life in the universe.  This post is a complaint about shoddy scientific inquiry (perhaps better described as non-scientific inquiry).

50 things we know now (we didn't know this time last year)

An excellent list, well worth the read.  I'm particular to #9: "brain reorganizes to make room for math", and #14: "Tai Chi may help control asthma"

Broccoli compound targets key enzyme In late-stage cancer

ScienceDaily notes, "An anti-cancer compound found in broccoli and cabbage works by lowering the activity of an enzyme associated with rapidly advancing breast cancer, according to a University of California, Berkeley, study appearing Dec 3 in the online early edition of the journal Proceedings of the National Academy of Sciences."

Device could filter cancer cells from blood

From PhysOrg: "In a new tactic in the fight against cancer, Cornell researcher Michael King has developed what he calls a lethal 'lint brush' for the blood -- a tiny, implantable device that captures and kills cancer cells in the bloodstream before they spread through the body."

Watching your dreams on a screen

I doubt the word "soon" in this article is accurate, but nevertheless this is both intriguing and a bit scary:

Fractal forest modelling

Not long ago I watched a Nova episode about fractals, titled "Hunting the Hidden Dimension".  The part of the show that I found most fascinating was the use of ratios to calculate the tree density in a forest by looking at just one tree.  It turns out that, at least in the study highlighted by this program, the ratio of limb sizes on a single tree strongly mirrored the ratio of tree sizes in any given section of the forest in which the tree was taken.

I find this quite fascinating, and since then have wondered if this ratio would hold at a smaller level.  Specifically, would the ratio of the vein lengths on the leaf correlate with the ratio of limb lengths on the tree and, thus, the tree sizes in the forest?
