Interesting Findings And World Unfolding Through My Eyes.

Happy World

I rest my head on this frightful earth,
my mind drifting without worry or hate.
I stand alone in this field
surrounded by golden dandelions.
They open themselves wide
spotting the green ocean.
They look for the sun
their hero, their savior.
So easy is this world, this field
no problems, no worries.
My field set before me
my world complete.
Important to the end:
the sun, me and you.
By Moore, who is one of my favourite poet

Few Most Annoying Things About Future

No self-driving cars, no virtual-reality PCs. For all the promise of futuristic technology, it ends up entering our lives as a series of annoyances: spam, impossible-to-open plastic packaging, those pagers you hold while waiting for your table at Applebee's. Laptop users invade our cafes. Cell phone rings interrupt our conversations. And the future will just make it worse.

1. Cell phones on planes: Airbus just got approved to enable onboard cell phone use in Europe. Though plane crews can enable a voice-off mode, don't bet on that being enforced during flights as airlines try to offer more convenience to business passengers. Imagine being stuck for seven hours with one half of a conversation. You'll want to grab the thing out of your neighbor's hand and flush it down the tiny airplane toilet.

2. Animated billboards: American cities are increasingly asked to legislate electronic billboards. Des Moines just decided that billboards can change images every eight seconds. The state of Arkansas set the same limit three weeks ago when it approved electronic billboards. (California may soon affirm the right to erect electronic billboards.) Expect advertising firms to push for lower minimums as the public gets used to the flashier advertising. If supporters can argue that the signs haven't caused accidents, it'll be harder to fight them with complaints of mere annoyance.

3. Aggressive in-car GPS: Triple-digit growth in GPS navigation units (over 3 million could be sold this year) means a huge number of drivers are dealing with the little gadgets that usually help them find their way -- but occasionally cause accidents and often just bug the hell out of them. Every time a GPS-using driver takes an unprogrammed exit from the highway to gas up, the navigation system recalibrates and announces the changes in that ubiquitous female voice. It'll sound eerily like this.

4. Camera-wearing freaks: Sure, the Justin.tv lifestream network now hosts streams from a dozen cameras, most attached to or pointing at one exhibitionist asshat (me, for example). But the real freaks to worry about are the camera-phone carriers that rapper Mike Skinner lamented in his latest album ("How the hell am I supposed to be able to do a line in front of complete strangers when I know they've all got cameras?"). Still-shot cameras are already standard-issue on phones, and mid-range phones now come with video cameras. Every digital camera takes thirty-second videos, and proper camcorders are pocket-sized and under 500 bucks. So if you don't want to end up on YouTube where a million children and losers will say "omg that was gay," just don't do anything stupid for the rest of your life, mmkay?

5. Even more iPods: Not to be a downer, but isn't it a bit depressing when everyone walks around with earphones in? iPods aren't just for rich folks, now that they cost as little as 80 bucks. Last Christmas put Apple over 20 million iPods sold in Q4. (Half that many were sold the quarter after -- the iPod's third-best quarter ever.) And who's buying them? The trendy cute members of the opposite sex that you wanted to talk to on the train. Or, of course, the annoying prick blocking your way in the mall.

6. Traffic cameras: Despite fights from driver advocacy groups, red-light cameras are still on the rise, and several states may reverse their bans on speed-violation cameras. Better wireless technology means quicker processing and more efficient systems that will replace traffic cops (who know that hey, you really tried to obey that light) with unmerciful computers. Will you bother going to court to fight the tickets, or will you just pay up?

7. Energy-saving wonks: Thanks liberals, for getting everyone riled up about energy consumption without any proper knowledge of the metrics. Under the inevitable Democratic regime to come, expect climate change to replace the war on terror as America's biggest fear. Also expect the public to get it just as wrong.

Just remember this: A full 17% of the nation's energy consumption -- including industrial, transportation, commercial and residential uses -- is from gasoline use. Another 6% is from diesel fuel. Replacing a daily car trip by biking or walking does more than all the unplugging of little electronic device chargers you learned about on some eager efficiency blog.

How To Control Tree Height

Forest scientists at Oregon State University have used genetic modification to successfully manipulate the growth in height of trees, showing that it’s possible to create miniature trees that look similar to normal trees – but after several years of growth may range anywhere from 50 feet tall to a few inches.

This is a “proof of concept” that tree height can be readily controlled by genetic engineering techniques. It opens the door to a wide variety of new products for the ornamental and nursery industries, experts say, if regulatory hurdles can be overcome – a big “if.”

The findings were recently published in the journal Landscape Plant News.

“From a science perspective, this is a very interesting accomplishment and there’s no doubt it could be made to work,” said Steven Strauss, a professor of forest science at OSU.

“But further development may be precluded by social, legal and regulatory obstacles,” he said. “Clearly there would be concerns whether the market for specialty tree products such as this would be strong enough to make it worth the large investments of time, money and testing that current regulation of genetically modified organisms would require, at least in the U.S.”

That aside, he said, it appears that with further research and development programs, it would indeed be possible to create an elm tree – which ordinarily would grow to 100 feet or more – that is only five feet tall at maturity, a charming addition that would fit nicely on a backyard deck. Or a 30-foot version that might be a better fit on urban streets. Or, in fact, just about any height in between. Other changes can also affect foliage shapes or color in very attractive ways, and some might have value in cleaning up environmental pollution.

In their studies, OSU scientists were able to create young poplar trees, which grow rapidly and can reach a mature height of 150 feet or more, that were anywhere from about 15 feet to a few inches tall after two years of growth. The smallest of them could be difficult to even find, tiny little “shrublets” among the flowers in the field site.

The manipulation of height growth was achieved by insertion of certain genes, mostly taken from the model plant Arabidopsis, which inhibited the action of a class of plant-specific hormones known as gibberellic acids. These compounds are also used as sprays to control the size and fruiting of orchard trees. In trees, the compounds promote the elongation of plant cells – when they are inhibited, the cells do not fully elongate, and plants remain short and stocky.

“It’s really interesting that these genes from Arabidopsis, which is a small plant in the mustard family, have been conserved through 50-100 million years of evolution and can perform more or less the same function in poplar trees,” Strauss said. “The modified trees themselves look pretty much normal, just a lot smaller, and a little more compact or bushy.”

Altogether, the researchers used seven distinct kinds of genes and more than 160 different types of genetic insertions to create about 600 genetically modified trees. All caused decreased signaling by gibberellic acids. They were grown in the field with USDA approval, and assessed several times for variation in size and appearance.

Other than reduced size, there appeared to be striking variation in foliage color and leaf shape, some of which might have significant ornamental value. Root development also appeared to be very strong, which might provide increased stress tolerance and have value where extensive root development is needed, such as in bioremediation of polluted soils or in very windy, limited soil moisture situations.

From an environmental viewpoint, the researchers said, dwarfed trees such as this are unlikely to be any kind of threat to spread,

Power Napping

The trick is the use sleep MP3’s such as these. They are essentially MP3’s that play white noise for the duration of the nap, and then slowly wake you up by playing a variety of sounds. Whats great is that you can play them on your computer speakers, or make them portable by putting them on your iPod or cell phone.


They are so helpful (and far superior to a traditional alarm clock) for a few reasons.

It’s too easy to make mistakes when setting an alarm for a nap. Alarm clocks are designed to be changed rarely, and used over and over at the same time each day. The math that is required to count x minutes ahead and get all the buttons right, while being sleep deprived, is just asking for errors.
Napping is not dependent on the time of day, it’s dependent on the length. The length of the mp3 never changes, so it is as simple as pressing play to get it right.
These mp3’s use white noise to block out other sounds and and soothe you to sleep. When I first heard it, I found it a little bit annoying, but I quickly grew to enjoy the sound, and it works better than earplugs to block out unwanted noises.
They wake you up gradually. Some start with relaxing clucking of chickens or a rooster, then play some music, and end with loud explosions and a human voice letting you know it’s time to get up if you still haven’t gotten up. This is much more effective (and pleasant) than a single tone that you will angrily turn off.
They are portable. I have one of these MP3’s on my blackberry so if I need to fall asleep, I just put in my standard headphones and I’m out. You can also carry them on your iPod.
Some finals tips for the perfect nap:

If you are sensitive to light, you may want to combine this with a sleep mask which will block out the light.

Make sure you are as warm as possible, since just having cold feet or hands can be enough to prevent sleep.
