Be Boring.

No! Say it ain’t so! The Overcoming Bias blog has this study from the Journal of Experimental Psychology that shows that interesting details interfere with learning:

In both experiments, as the interestingness of details was increased, student understanding decreased (as measured by transfer). Results are consistent with a cognitive theory of multimedia learning, in which highly interesting details sap processing capacity away from deeper cognitive processing of the core material during learning.

I reject this. As a parakeet-style “Oh, pretty!” learner and collector of shiny trivia, I feel like my brain has just come under attack! What about context, man? What about the human element? Don’t take my bizarre connections away!

Charles R. Knight is a scientific illustrator more people need to know about. A paleoartist, even.

He brought dinosaurs (and other things) to life.

Future: 2008 Energy Breakthroughs

The Memebox FutureBlogger rings in the New Year with the top 10 energy breakthroughs from 2008:

There is still a lot we do not know about the basics of energy systems dealing with photons, carbon, hydrogen, oxygen, enzymes and metals. Our current first phase efforts to design nanoscale materials used in energy production, conversion and storage are certain to yield systems that will change how we live in the world in the decades ahead.

Remember, only a century ago, coal and wood were king, magical ‘electric’ light intimidated the general public, only a few could see the potential of oil, rockets and nuclear science were beyond our imagination, and the vision of a tens of millions of ‘horseless carriages’ reshaping the urban landscape was a ridiculous proposition.

So what seemingly novel ideas could shape the next century?

The list runs from hydrinos (very small) to planetary fusion (very big). There are a few surprising things along the way.

Cell Phone Blood Scanner

Bet your iPhone can’t do this…. UCLA scientists have found a way to rig an ordinary cell phone, an LED, a light filter and some wiring together, Wired reports, into a cheap and easy blood scanner that can detect HIV and malaria, among other diseases:

UCLA researcher Dr. Aydogan Ozcan images thousands of blood cells instantly by placing them on an off-the-shelf camera sensor and lighting them with a filtered-light source (coherent light, for you science buffs). The filtered light exposes distinctive qualities of the cells, which are then interpreted by Ozcan’s custom software.

Future By Colani.

Here, something pretty for your Yule: How Luigi Colani designed the future.

^{A Colani-designed semi-trailer.}

From steam trains to flying boats.

Spacecraft like ginger flowers and orange peels.

You can see more of Colani’s biodesign on his Swiss web site (warning: the main page launches a flurry of pop-ups) or the German one, or just read about him here or here.

from www.colani.ch:
“Whenever we talk about biodesign we should simply bear in mind just how amazingly superior a spider’s web is to any load-bearing structure man has made – and then derive from this insight that we should look to the superiority of nature for the solutions. If we want to tackle a new task in the studio, then it’s best to go outside first and look at what millenia-old answers there may already be to the problem.”

ARTIST: grant.

SOURCE: “Antarctica Has More Species than Galapagos”, LiveScience, 2 Dec 2008, as used in the post “Life On Ice.”

ABSTRACT:
I remain amazed at how many different things thrive deep under the ice.

There are no polychaetes
and isopods
in my aquarium today

The bryozoans and
the isopods
are probably happier that way.

Given more time to work on this song, I’d simply layer on more vocal tracks. Many more.

Smart Soldiers Die First.

Sounds grim, but New Scientist says it’s true. The more intelligent soldiers were the most likely to die in combat:

The unprecedented demands of the second world war – fought more with brains than with brawn compared with previous wars - might account for the skew, says Ian Deary, a psychologist at the University of Edinburgh, who led the study. Dozens of other studies have shown that smart people normally live longer than their less intelligent peers.

“We wonder whether more skilled men were required at the front line, as warfare became more technical,” Dear says.

His team’s study melds records from Scottish army units with results of national tests performed by all 11-year-olds in 1932. The tests assessed verbal reasoning, mathematics and spatial skills.

“No other country has ever done such a whole-population test of the mental ability of its population,” Deary says.

It may be that higher IQs translated to better speaking ability - which led to battlefield promotions. Or, it could be that intelligent soldiers tried to do everything just right, which meant they were likelier to wind up in dangerous situations.

I can easily picture the kind of obsessed problem solver who aces IQ tests sitting in a bunker frantically assembling a detonator exactly right without realizing the tanks are only 10 feet away and everyone else has split.

There’s more on the study at the journal Intelligence.

Electric Plonk.

New Scientist gives us a recipe for converting cheap wine to the good stuff:

It is backed by a decade of research, the results have been published in a peer-reviewed journal and the end product has passed the ultimate test- blind tasting by a panel of wine experts. No fewer than five wineries have now invested in the technology.

The secret this time is an electric field. Pass an undrinkable, raw red wine between a set of high-voltage electrodes and it becomes pleasantly quaffable. “Using an electric field to accelerate ageing is a feasible way to shorten maturation times and improve the quality of young wine,” says Hervé Alexandre, professor of oenology at the University of Burgundy, close to some of France’s finest vineyards.

…

During ageing, wine becomes less acid as the ethanol reacts with organic acids to produce a plethora of the fragrant compounds known as esters. Unpleasant components precipitate out and the wine becomes clearer and more stable. Red wines mellow as bitter, mouth-puckering tannin molecules combine with each other and with pigment molecules to form larger polymers, at the same time releasing their grip on volatile molecules that contribute to the wine’s aroma.

…

The results were striking. With the gentlest treatment, the harsh, astringent wine grew softer. Longer exposure saw some of the hallmarks of ageing emerge- a more mature “nose”, better balance and greater complexity. The improvements reached their peak after 3minutes at 600 volts per centimetre: this left the wine well balanced and harmonious, with a nose of an aged wine and, importantly, still recognisably a cabernet sauvignon.
