+ - Fish raised on land give clues to how early animals left the seas->

Submitted by sciencehabit
sciencehabit (1205606) writes "When raised on land, a primitive, air-breathing fish walks much better than its water-raised comrades, according to a new study. The landlubbers even undergo skeletal changes that improve their locomotion. The work may provide clues to how the first swimmers adapted to terrestrial life. The study suggests that the ability of a developing organism to adjust to new conditions—its so-called developmental plasticity—may have played a role in the transition from sea to land."

You think your argument is strong with Sun containing 98% of the Solar system's total mass? It is actually something like 99.8%!!

Yep. Here's a good source for the relative masses of the solar system object: It does not include the Oort Cloud, which is though to contain about 5 Earth masses of material.

Might it be one of the most expensive movies ever?

Asks an ignorant troll...

Considering it was made with 25 year old footage, it was probably one of the cheapest movies ever made.

The U.S. spends $324 billion dollars a year on entertainment*. tThe cost of the Voyager II program ($865 million dollars*) over 40 years is equal to about 22 millon dollars per year. A drop in the bucket. The Pioneer and Voyager missions have spawned an entire cottage industry of "science-based edutainment shows" on TV like "Through the Wormhole" and "Cosmos". That program has paid for itself many, many times over.

How do we determine how much to spend on stuff with little or no payback?

I have no idea. But the Voyager mission has certainly paid for itself many times over.

Just wait until the AI has to keep track of liability awards so that it can make the correct decision regarding minimizing liability. At some point you are going to have a stupid jury award and all the cars are just going to refuse to go anywhere because the AI's cost benefit analysis says "just stay in park".

Reading comprehension is such a lost art these days. It was the H1N1 virus that caused the pandemic, which the Chinese scientists used in their research; not the results of the Chinese research that caused the pandemic.

From the cited article:

a team of Chinese scientists to create a hybrid viral strain between the H5N1 avian influenza virus and the H1N1 human flu virus that triggered a pandemic in 2009 and claimed several thousand lives.

For those challenged individuals, this sentence fragment should be parsed as:

(a team of Chinese scientists) ... (create a hybrid viral strain) (BETWEEN) (the H5N1 avian influenza virus) AND (the H1N1 human flu virus that triggered a pandemic in 2009 and claimed several thousand lives).

As a developer in the industry here I can honestly say nobody in our industry would be dumb enough to use this tool.

Bullshit. As a (former) developer in the industry (still a developer; no longer in the industry) I can honestly say plenty of people in your industry would be dumb enough to use this tool. Especially when some wide-eyed "Oracle DBA(sm)" tells them "I heard about it at Oracle World -- of course it's secure." Seriously -- it is not like retailers hire the best and the brightest. And virtually every online retailer I deal with keeps my CC information on file. Most of them are hard-working, understaffed developers just trying to get the job done and do the bare minimum to meet PCI compliance -- because that is what management wants.

The surgeon knows his job and does it with great freedom. He/She 'just do' brain surgery

Nobody would survive a brain surgery if a physician would have to go through the same hurdles as a professional programmer

Very true. By the same token, by the time your average programmer was done with your brain surgery, you'd have toenails growing out of your asshole for some inexplicable reason. "Oh, we'll fix that in the next surgery." *That* is why we have "clueless" administrators pre-approving their shit.

The brain surgeon has to be worried about malpractice lawsuits; the programmer does not. The brain surgeon requires board certification; the programmer does not. The brain surgeon requires twice the education and years of formal, on the job training before he is ever allowed to operate; your average programmer thinks he/she can write shit-hot code before they even graduate.

The bigger injustice is that mathematics has become an elite: a vocation requiring rare talents, grueling training, and total dedication. The way things are today if you want to be a mathematician you had best be someone like me on the autism spectrum who has spent their entire life mastering vast realms of arcane knowledge — and enjoys it. Normal humans are effectively excluded from contributing to the field of mathematics. The real injustice of mathematics inequality is that it doesn’t have to be this way.

Yeah... that feels about right.
