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".
“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.
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.
Mike joined ELO in 1972 and the band hit the big time with a version of Roll Over Beethoven.
Mike - known for his bizarre costumes and eccentric style which included plucking his strings with fruit - left in January 1975 to become a Buddhist.
He later changed his name to Deva Pramada and is thought to have remained single. Police are trying to trace his family.
"There seems to be an axis through the cosmos. In one direction, the universe seems to be getting bigger, while in the opposite direction it's getting smaller, not by very much, but it seems to do so significantly."
He found that a steady 63-mile-per-hour (100-kilometer-per-hour) wind over a digitally reconstructed east-west running lake at the Mediterranean end of the Nile, near today's Port Said, would push the water west to the far end of the lake as well as south up the river
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.
"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."
If correct, the discovery could mean only our part of the Universe may be capable of supporting life.
If true, this would violate what most cosmology texts call the Cosmological Principle (or the Copernican Principle)
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.
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!"
The news in here isn't meant to pick apart really.
For the layman, strength and force would be interchangable. A scientist might be more careful.
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!

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 only have to look up at the sky on a clear night and see the countless stars. Numerator or denominator, which is bigger? Probabilities.

We were talking about the "fine-tuned universe" idea, right? Not about life on other planets but life in (areas in) universes which are differently tuned.
