Test Tube DNA Brain Gets Quiz Questions Right

Neuron-SEM-2A step closer to artificial intelligence? Discovery News reports:

A team of researchers lead by Lulu Qian from the California Institute of Technology (Caltech) have for the first developed an artificial neural network — that is, the beginnings of a brain — out of DNA molecules. And when quizzed, the brain answered the questions correctly.

They turned to molecules because they knew that before the neural-based brain evolved, single-celled organisms showed limited forms of intelligence. These microorganisms did not have brains, but instead had molecules that interacted with each other and spurred the creatures to search for food and avoid toxins. The bottom line is that molecules can act like circuits, processing and transmitting information and computing data.

The Caltech used DNA molecules specifically for the experiment, because these molecules interact in specific ways determined by the sequence of their four bases: adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T).

Can AI-Powered Games Create Super-Intelligent Humans?

EinsteinA technology CEO sees game artificial intelligence as the key to a revolution in education, predicting a synergy where games create smarter humans who then create smarter games.

Citing lessons drawn from Neal Stephenson’s The Diamond Age, Alex Peake, founder of Primer Labs, sees the possibility of a self-fueling feedback loop which creates “a Moore’s law for artificial intelligence,” with accelerating returns ultimately generating the best possible education outcomes.

“What the computer taught me was that there was real muggle magic …” writes Peake. And he reaches a startling conclusion.

“Once we begin relying on AI mentors for our children and we get those mentors increasing in sophistication at an exponential rate, we’re dipping our toe into symbiosis between humans and the AI that shape them.

Secret of NIMH? Memory Implant Boosts Brain Function in Rats

Secret of NIMHThis article reminds me a bit of The Secret of NIMH. Yes, my first awareness of animal experimentation was likely from a(n) Disney animated movie. Benedict Carey writes in the New York Times:

Though still a long way from being tested in humans, the implant demonstrates for the first time that a cognitive function can be improved with a device that mimics the firing patterns of neurons. In recent years neuroscientists have developed implants that allow paralyzed people to move prosthetic limbs or a computer cursor, using their thoughts to activate the machines.

In the new work, being published Friday, researchers at Wake Forest University and the University of Southern California used some of the same techniques to read neural activity. But they translated those signals internally, to improve brain function rather than to activate outside appendages.

“It’s technically very impressive to pull something like this off, given our current level of technology,” said Daryl Kipke, a professor of bioengineering at the University of Michigan who was not involved in the experiment.

Even If You Are an Atheist, You Worship Something …

From the late great David Foster Wallace:

Because here’s something else that’s true. In the day-to-day trenches of adult life, there is actually no such thing as atheism. There is no such thing as not worshiping. Everybody worships.

The only choice we get is what to worship. And an outstanding reason for choosing some sort of God or spiritual-type thing to worship — be it J.C. or Allah, be it Yahweh or the Wiccan mother-goddess or the Four Noble Truths or some in-frangible set of ethical principles — is that pretty much anything else you worship will eat you alive.

If you worship money and things — if they are where you tap real meaning in life — then you will never have enough. Never feel you have enough. It’s the truth.

Worship your own body and beauty and sexual allure and you will always feel ugly, and when time and age start showing, you will die a million deaths before they finally plant you.

Translation Machine To Make Human-Dolphin Conversations Possible

flipperWhat secrets of the sea have dolphins been waiting to tell us? We may soon find out (hopefully not just tuna jokes). New Scientist reports:

A diver carrying a computer that tries to recognize dolphin sounds and generate responses in real time will soon attempt to communicate with wild dolphins off the coast of Florida. If the bid is successful, it will be a big step towards two-way communication between humans and dolphins.

Since the 1960s, captive dolphins have been communicating via pictures and sounds. In the 1990s, Louis Herman of the Kewalo Basin Marine Mammal Laboratory in Honolulu, Hawaii, found that bottlenose dolphins can keep track of over 100 different words. They can also respond appropriately to commands in which the same words appear in a different order, understanding the difference between “bring the surfboard to the man” and “bring the man to the surfboard”, for example.

But communication in most of these early experiments was one-way, says Denise Herzing, founder of the Wild Dolphin Project in Jupiter, Florida.

UK Court Bans Man With Low IQ From Having Sex

No SexMartin Beckford writes in the Telegraph:

A man with a low IQ has been banned from having sex by a High Court judge who admitted the case raised questions about “civil liberties and personal autonomy”.

The 41 year-old had been in a relationship with a man whom he lived with and told officials “it would make me feel happy” for it to continue. But his local council decided his “vigorous sex drive” was inappropriate and that with an IQ of 48 and a “moderate” learning disability, he did not understand what he was doing.

A psychiatrist involved in the case even tried to prevent the man being given sex education, on the grounds that it would leave him “confused”. Mr Justice Mostyn said the case was “legally, intellectually and morally” complex as sex is “one of the most basic human functions” and the court must “tread especially carefully” when the state tries to curtail it.

Why Rich Parents Don’t Matter

Annie& Daddy WarbucksInteresting article from Jonah Lehrer in the Wall Street Journal:

How much do the decisions of parents matter? Most parents believe that even the most mundane acts of parenting — from their choice of day care to their policy on videogames — can profoundly influence the success of their children. Kids are like wet clay, in this view, and we are the sculptors.

Yet in tests measuring many traits, from intelligence to self-control, the power of the home environment pales in comparison to the power of genes and peer groups. We may think we’re sculptors, but the clay is mostly set.

A new paper suggests that both metaphors can be true. Which one is relevant depends, it turns out, on the economic status of families.

For a paper in Psychological Science, researchers at the University of Texas at Austin and the University of Virginia looked at 750 pairs of American twins who were given a test of mental ability at the age of 10 months and then again at the age of 2.

Ex-Intelligence Officers, Others See Plusses in WikiLeaks Disclosures

WikiLeaks has teased the genie of transparency out of a very opaque bottle, and powerful forces in America, who thrive on secrecy, are trying desperately to stuff the genie back in. The people listed below this release would be pleased to shed light on these exciting new developments.

How far down the U.S. has slid can be seen, ironically enough, in a recent commentary in Pravda (that’s right, Russia’s Pravda): “What WikiLeaks has done is make people understand why so many Americans are politically apathetic … After all, the evils committed by those in power can be suffocating, and the sense of powerlessness that erupts can be paralyzing, especially when … government evildoers almost always get away with their crimes. …”

So shame on Barack Obama, Eric Holder, and all those who spew platitudes about integrity, justice and accountability while allowing war criminals and torturers to walk freely upon the earth.
