Researchers have discovered the skull of a 29 million-year-old animal that could be a common ancestor of Old World monkeys and apes, including humans.
"If we knew something about the time period and the condition this animal was living in, we might be able to discover what brought about the changes that led to [the evolution of] apes and humans".

"The overall working hypothesis of this proposal is that the magnitude of the sexual response depends on several cocaine preexposure parameters including dose, amount of exposure, time between exposures, and the withdrawl period before sexual behavior testing," says the grant description
The Web site also said, "Finally quail provide a convenient and interesting alternative to standard laboratory rats and pigeons."

Romantic Breakup Similar to Overcoming Addiction
“This brain imaging study of individuals who were still ‘in love’ with their rejecter supplies further evidence that the passion of ‘romantic love’ is a goal-oriented motivation state rather than a specific emotion,” the researchers concluded, noting that brain imaging showed some similarities between romantic rejection and cocaine craving.
Spacequakes Rumble Near Earth

Spacequakes Rumble Near Earth (see movie)
Researchers using NASA's fleet of five THEMIS spacecraft have discovered a form of space weather that packs the punch of an earthquake and plays a key role in sparking bright Northern Lights. They call it "the spacequake."
"We've long suspected something like this was happening," says Sibeck. "By observing the process in situ, however, THEMIS has discovered something new and surprising."
The surprise is plasma vortices, huge whirls of magnetized gas as wide as Earth itself, spinning on the verge of the quaking magnetic field.

Aha, the real reason of all the immodest stressing of masculine thinking here!
The idea that a modern man who is modest and metrosexual has features women find attractive appears to be a myth, according to a new study published in the peer-reviewed journal Psychology of Men and Masculinity. Researchers found that females see modesty and men's feminine side as a big turn-off.

From Primitive Parts, A Highly Evolved Human Brain
- We're still using a communication system developed 600 million years ago by jellyfish. "If our neurons weren't such lousy processors and we didn't need 100 billion of them massively interconnected in order to make a clever brain out of such lousy parts, then we wouldn't have such a long childhood," Linden says.
And without that long childhood, he says, evolution wouldn't have equipped us with the force that bonds parents together to protect their children.

new fabrication technique
Xiangfeng Duan and colleagues the University of California at Los Angeles have developed a new fabrication technique that involves employing alumina-coated nanowires as the gate electrode in a graphene transistor. The device's source and drain electrodes are then made using a self-aligning process using the nanowires as "masks" – a process that also minimizes resistance in the transistor, so improving its performance even further.

Re: In the News
Hi Diebert - I took a look at your first link above.
I think one should take this article with a few grains of salt. In it, Stuart Gray writes:
The research points to this:
This would indeed be big news!
However, the article swiftly speculates:
Remember, this is a slight difference in a dimensionless ratio (roughly 1/137). I can still recall a university cosmology physics lecture where the professor was making a mathematical argument on the board and ended by ignoring a factor of 2pi. "We don't worry about things like two times or three times when we are talking about outer space. We just pay attention to orders of magnitude to see whether we are on the right track!"
I think one should take this article with a few grains of salt. In it, Stuart Gray writes:
The fine-structure constant is a dimensionless ratio associated with the electromagnetic field. It is not a force of any kind.Australian scientists have detected a spatial variation in the fine structure constant, one of the fundamental forces of nature that binds electrons to the nuclei of the atom.
The research points to this:
If true, this would violate what most cosmology texts call the Cosmological Principle (or the Copernican Principle): "The Universe is homogeneous and isotropic in three-dimensional space, has always been so, and will always remain so." (Introduction to Cosmology, Roos, 2003)"This means in one direction, the fine structure constant was once smaller and in exactly the opposite direction, it was once bigger. And here we are in the middle, where the constant is about 1/137."
This would indeed be big news!
However, the article swiftly speculates:
How quickly it becomes fodder for anthropological debate. If true, the discovery "means" no such thing. Because if it weren't true, we would still have no idea if there is life in any other "part" of the universe, only that we had no a priori reason to suspect that there may not be, since we would have physical laws the same everywhere. If it is true, we have no reason to suppose a differential fine structure constant would preclude life rather than make it more probable.If correct, the discovery could mean only our part of the Universe may be capable of supporting life.

Re: In the News
The news in here isn't meant to pick apart really. I mean, where to start? :-)
It's a bit nitpicking though, the FSC can be said to measure a specific strength in a couple of interpretations. For the layman, strength and force would be interchangable. A scientist might be more careful.

That would be the stunning implication indeed.If true, this would violate what most cosmology texts call the Cosmological Principle (or the Copernican Principle)
It's not a question of probability. The whole mathematical and theoretical framework needed to even speculate about formation of matter, organic molecules and such while using other constants is just not there. So there's good reason to suppose preclusion. But the preclusion doesn't have to become a cosmological absolute constant itself. It remains current understanding with firm conclusions being part of that - all relatively!Because if it weren't true, we would still have no idea if there is life in any other "part" of the universe, only that we had no a priori reason to suspect that there may not be, since we would have physical laws the same everywhere.

The difference is that there's no mathematical path to the number. It's "just there" when there's stuff like electrons and photons around.Remember, this is a slight difference in a dimensionless ratio (roughly 1/137).

Where to start?
Says who? A forum is where one discusses things. You posted a link. I respect you by following that link and reading the article. Then what? Wait for you to post another link and follow that one? I am commenting on a link you posted!
I personally see no reason to assume or preclude the possibility of life elsewhere in in the universe. If conditions were just so that life began spontaneously here on earth at one point in time and I believe that such highly unlikely conditions are a prerequisite for life to start itself, I only have to look up at the sky on a clear night and see the countless stars. Numerator or denominator, which is bigger? Probabilities.

Well maybe I think that is just not good enough for a "genius" forum. I do not purport to be either a genius or a scientist, and this error in the author's writing was the first thing I noticed. I assume most geniuses and or scientists would notice it as well.For the layman, strength and force would be interchangable. A scientist might be more careful.
Of course it is a question of probability! If this finding pans out, I am pretty sure most physicists would not discard the "whole mathematical and theoretical framework" that exists concerning the formation of matter as a result. When something uncertain is under consideration, one considers how likely competing scenarios are to be true, given the empirical information. Since we do not know and can only speculate about life elsewhere in the universe, we are speaking of likelihoods and not certainties.It's not a question of probability. The whole mathematical and theoretical framework needed to even speculate about formation of matter, organic molecules and such while using other constants is just not there.
What good reason does this specific finding offer? We can just as well suppose preclusion because we only know that life exists on this planet. If the FSC were different in another part of the universe, presumably some of the laws of physics we know to date would not apply to that part. Is that the same as saying no laws would apply? I think we can assume some perhaps modified laws would hold. Why would one then assume these modified laws would be less conducive to life existing in that part of the universe? Because life is so evidently abundant in this part? All we know for sure is that there is life on this planet, and we are speaking in cosmological terms. That is a huge difference.So there's good reason to suppose preclusion.
What firm conclusions and whose current understanding?But the preclusion doesn't have to become a cosmological absolute constant itself. It remains current understanding with firm conclusions being part of that - all relatively!

Well, with small variations the laws of physics wouldn't allow for heavy elements to bind. That would mean no planets, for starters.If the FSC were different in another part of the universe, presumably some of the laws of physics we know to date would not apply to that part. Is that the same as saying no laws would apply?
If you want to speculate about non-carbon based lifeforms or intelligent blue clouds drifting between planets, I'm all for it! But that isn't science as you found so important to point out before.I only have to look up at the sky on a clear night and see the countless stars. Numerator or denominator, which is bigger?

Re: In the News
You might be all for such speculation, but I wouldn't share the enthusiasm. You are bringing up intelligent blue clouds, whatever that is supposed to be, and NCLFs, and I suppose you are doing so for a reason, but the reason escapes me, which is fine with me. All I was saying is that no matter how unlikely the outcome life is, we do know it has happened once. That means it is not impossible. Repeat a trial enough times when an outcome has a nonzero probability of occurring and eventually you get that outcome. How many trials? How many suitable stars are there and have there been? I think it is folly to suppose this one planet contains all the life in the entire universe, but it is a common one for an egocentric outlook.Diebert wrote:If you want to speculate about non-carbon based lifeforms or intelligent blue clouds drifting between planets, I'm all for it!

Re: In the News
What the article referred to here was the idea of the fine-tuned Universe. Then you somehow tried to make the phrase "could mean" found in a popular science article into some absolute position which you then started to attack. Of course the fine-tuning argument is heavily debated but in my view the scientific consensus is that things certainly look tuned toward development of life as we know it and many calculated models still support it. Therefore it remains a reasonable statement in the context of the discovery to suggest life might be only possible in certain pockets in the Universe because of its varying structure. It certainly isn't fodder for "anthropological debate", perhaps you meant anthropocentric?cousinbasil wrote: The article itself brought up life in other parts of the universe.
