Twins different DNA sparks parents divorce

Posted by Xeno on February 2, 2010

http://www.damninteresting.net/content/heteropaternal_superfecundation.jpgA Turkish man decided to divorce his wife after DNA tests showed he was the father of only one of their twin boys, the mass-circulation Sabah newspaper has reported. Suspicious that his wife had been unfaithful the security guard from Istanbul identified only as AK, had DNA tests performed on the three-year-olds. The tests established with a 99.99 per cent certainty that he was the father of only one of the boys, Sabah reported, adding that the result was CONFIRMed by a forensic medicine institute upon the request of the court handling the ongoing divorce case. The mother, identified as CK, had maintained a relationship with a lover she had dated before her family forced her to marry AK, the daily said. The phenomenon of twins with different fathers, known scientifically as heteropaternal superfecundation, is very rare in humans, though more common in animals such as cats and dogs. It becomes possible in rare circumstances when a woman produces two ova in one menstrual cycle, explained Professor Rusen Aytac, head of the gynaecology department at Ankara University s medical faculty. And if this woman has sexual intercourse with two different men at short intervals, this can result in a twin pregnancy, with each egg carrying a different genetic material, he said. AK kept the boy he had fathered and disowned the other one, which ended up in a state care institution, Sabah said. CK, for her part, has received death threats both from her own and her husband s family and secured a court order preventing relatives from coming within 500 metres of her, it added.

Corporations are not people and money is not speech

Posted by Xeno on February 2, 2010

Regarding the recent really bad decision by the Supreme Court to allow corporations to bribe politicians as never before in our country’s history, I liked these comments on the WRH web site:

http://www.opensecrets.org/news/us_supreme_court.jpgIn Citizens United v. Federal Election Commission, the U.S. Supreme Court overturned century-old restrictions on corporate spending in elections under the guise of protecting First Amendment free speech rights. …

Corporations, however, are inherently not the same as individuals and thus cannot have the same protections as individuals. There are a slew of laws that protect corporations and their interests in the arena for which they are by definition formed—namely the marketplace. The laws that govern corporations and the rights enjoyed by them are distinct from the laws and rights of individuals. A corporation, for example, can enter into contracts like an individual, but unlike an individual, a corporation’s members can be protected by limited liability so their personal assets are not at stake.

Webmaster’s Commentary:

If a corporation is a legal person, then under the 13th Amendment they may not be owned by, nor may they own, other persons (corporations).

If the 13th Amendment does not apply to a corporate person, then neither does the 1st.

A corporation is not engaging in free speech. Corporations are not sentient. At best they are immortal imbeciles unable to speak much less vote under the total control of their owners/guardians. The owner/guardians are normal human beings, and while they may spend as much of their own personal fortunes as they wish to exercise their right of free speech, spending the assets of the non-sentient creature in their charge may be misappropriation.

Toyota issues public apology, details plan to fix pedals

Posted by Xeno on February 2, 2010

http://i.usatoday.net/communitymanager/_photos/drive-on/2010/02/01/pedalx-wide-community.jpg… Toyota chief executive Akio Toyoda addressed the issue on Friday with Japanese broadcaster NHK at the World Economic Forum in Davos, Switzerland, saying:

“I am very sorry that we are making our customers feel concerned. . . . People can feel safe driving in the current situation.” But the statement by Lentz was the first apology aimed at a U.S. audience by a senior Toyota official.The problem involves a friction device that is supposed to provide the proper “feel” in the pedal by adding resistance and making it steady and stable, the automaker said.

Over time, however, parts of the friction device have begun to stick instead of operating smoothly.The solution is a steel reinforcement bar, which, when installed into the assembly, will eliminate the excess friction.

“The company has confirmed the effectiveness of the newly reinforced pedals through rigorous testing on pedal assemblies that had previously shown a tendency to stick,” the company said in a statement Monday.

“Toyota has done the right thing by providing a remedy for this serious safety issue,” Transportation Secretary Ray LaHood said in a conference call with reporters.

Separately, the company has recently recalled cars in which floor mats can cause the accelerator pedal to become stuck in the depressed position. About 2.1 million vehicles are affected by both the pedal and floor-mat recalls, Toyota said. With the new fix, the company hopes that both problems will be resolved. “Between these two things, this should be under control,” Lentz said.

So, come on… was there really ever any actual problem with floor mats?  According to the story I heard and posted, this happened in a new Prius during a test drive at a dealership. That doesn’t sound like a candidate for parts being worn down over time, so I wonder if the Prius still has some electronic problem. Time will tell.

A brain perspective: Why is it so difficult to learn absolute pitch?

Posted by Xeno on February 2, 2010

I’m home sick with a nasty cough. After sleeping as much as possible, I took a steamy bath to help my lungs and played with an iPhone app called “Perfect Pitch Lite” by Steven Elliott. I made about zero progress in the course of an hour.

Then I gave up and watched a TED talk from 2007 by Jeff Hawkins on how brain science will change computing. This got me thinking in a new direction about acquiring absolute pitch.

Treo creator Jeff Hawkins urges us to take a new look at the brain — to see it not as a fast processor, but as a memory system that stores and plays back experiences to help us predict, intelligently, what will happen next.

The memory-prediction framework is a theory of brain function that was created by Jeff Hawkins and described in his 2004 book On Intelligence. This theory concerns the role of the mammalian neocortex and its associations with the hippocampus and the thalamus in matching sensory inputs to stored memory patterns and how this process leads to predictions of what will happen in the future.

According to Jeff, my brain is good at learning sequences because the primary function of my neo-cortex is to predict things. This explains why my brain never bothered to store exact pitches. It was more adaptive and intelligent to have good relative pitch. That way, I could sing in tune with an out of tune group and “fit in” socially and musically.

As a musician, I’ve spent most of my life playing and singing in tune with whatever instrument is at hand, not caring about absolute pitch as long as the instrument I played was tuned to itself.

Still, I’m driven by challenges.

Can I learn a fundamentally new way of hearing after twenty years?

Can the memory-prediction framework help me learn absolute pitch? I’m going to sleep on that and see if my subconscious can tell me the answer to how to program my brain.

A bit more reading show another interesting theory, that absolute pitch may not require any new learning. This is why I can’t seem to learn it. It may instead require blocking something I have already learned.

Absolute pitch accessible to everyone by turning off part of the brain?

TERRY BOSSOMAIER and ALLAN SNYDER

The authors argue that infants are all born with absolute pitch and that this is suppressed in most people as we learn language. Some people who are exposed to musical instruments when they are learning language are tricked into developing special language centers for musical tones.
Perhaps brain stimulation, the authors argue, can unleash absolute pitch ability. They base this idea on the fact that TMS (Transcranial Magnetic Stimulation) applied
“to the left frontotemporal lobe enabled normal individuals to exhibit savant-like skills in drawing and in proofreading. Such magnetic stimulation is known to inhibit the normal functioning of localised regions of the brain…”
As yet no area in the brain has been identified which could be suppressed and would then unleash absolute pitch skills.
This brings me back to a point I’ve considered in the past. To what degree can we consciously disable our own memories?
I know it is possible, with hypnosis, and perhaps with self-hypnosis to have a negative visual hallucination, where you can not see something that is really in your environment. This kind of control would help with my supposedly incurable tinnitus.
I looked up “conscious forgetting” and found these tidbits:
Conscious forgetting means willfully dropping the practice of obsessing, intentionally outdistancing and losing sight of it, not looking back, thereby living in a new landscape, creating new life and new experiences to think about instead of the old ones. This kind of forgetting does not erase memory, it lays the emotion surrounding the memory to rest.”
Anderson and Gabrieli discovered that when people consciously determine not to think about something they do not want to remember, their ability to recall that memory gradually weakens. – link
“If you consistently expose people to a reminder of a memory that they don’t want to think about, and they try not to think about it, they actually don’t remember it as well as memories where they were not presented with any reminders at all.”- link
Great, so I just have to figure out what it is that I want to forget that will let me recall pitches.
