"Nothing much is going to happen in the next 10 years. Of course, that’s not counting the diesel-excreting bacteria, the sequencing of your entire genome for $1,000, massive banks of frozen human eggs, space tourism, the identification of dark matter, widespread sterilisation of young adults, telepathy, supercomputer models of our brains, the discovery of life’s origins, maybe the disappearance of Bangladesh and certainly the loss of 247m acres of tropical forest. As I said, just another decade really. These days, “just another decade” always means 10 years of future shock. Science, technology and the contemporary mania for change combine to stun the imagination. It is the way we live now, in a condition of permanent technological revolution."

"It’s known as the golden hour. After a bullet wound or other massive trauma, soldiers in the field have about one hour to get intense medical attention. After that time, the chances of survival drop drastically. The research arm of US armed forces, DARPA, has long been interested in extending that golden window of opportunity to five or six hours, enough time to medevac someone from a remote location to a hospital. Earlier in December, DARPA announced that the Texas A&M Institute for Preclinical Studies (TIPS) would be receiving $9.9 million in funding to determine if previously successful suspended animation programs for rodents could work with pigs. According to Wired, the 15 person team lead by Dr. Matthew Miller hopes to have positive results in just 18 months. That sort of quick paced research could soon pave the way to preserve trauma victims the world over as they make their way to help."

"A newly-discovered planet orbiting a small, nearby star appears to be a "water world," with a surface that might be covered with liquid water. "This is certainly the first planet around another star which we think is mostly made of water," says David Charbonneau of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who led the research team that found the new planet, named GJ 1214b."

"A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time. According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second. However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory. The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of prisms that had been moved up to 3ft apart. Being able to travel faster than the speed of light would lead to a wide variety of bizarre consequences. For instance, an astronaut moving faster than it would theoretically arrive at a destination before leaving. The scientists were investigating a phenomenon called quantum tunnelling, which allows sub-atomic particles to break apparently unbreakable...

"Or so says Australian psychologist, Joe Forgas, who seems to think a case of the “grumps” can, in fact, make us think more clearly. The University of New South Wales researcher says grumpy people, rather than happy types, are better at coping with demanding situations because of the way the brain “promotes information processing strategies.” ... Professor Forgas said: ‘Whereas positive mood seems to promote creativity, flexibility, co-operation and reliance on mental shortcuts, negative moods trigger more attentive, careful thinking, paying greater attention to the external world.’"

"Coffee contains caffeine, and as everyone knows, caffeine is a stimulant. We all know how a good cup of coffee wakes you up, makes you more alert, and helps you concentrate - thanks to caffeine. Or does it? Are the benefits of coffee really due to the caffeine, or are there placebo effects at work? Numerous experiments have tried to answer this question, but a paper published today goes into more detail than most.."

"This isn't just another Branson lark, like the ocean crossings via hot air balloon. Virgin Galactic plans to capitalize on the fact that 90 percent of people, in Branson's estimation, would like to go into space "if we can guarantee a return ticket." Plus, the company hopes to become a private launcher of commercial satellites, putting some of the burgeoning number of orbiting machines into space for a fraction of the going rate."

"Using their approach to “write directly to memory,” scientists can now obtain a level of evidence about brain function that was impossible before, Miesenböck said. He notes that neuroscience for a long time depended primarily on recording brain activity and attempting to correlate it to perceptions, actions, and cognition. But “it’s more powerful to seize control of the relevant brain circuits and produce these states directly,” he said."

Roger Penrose Says Physics Is Wrong, From String Theory to Quantum Mechanics | Discover Interview: Cosmology | DISCOVER Magazine - http://discovermagazine.com/2009...
"Roger Penrose could easily be excused for having a big ego. A theorist whose name will be forever linked with such giants as Hawking and Einstein, Penrose has made fundamental contributions to physics, mathematics, and geometry. He reinterpreted general relativity to prove that black holes can form from dying stars. He invented twistor theory—a novel way to look at the structure of space-time—and so led us to a deeper understanding of the nature of gravity. He discovered a remarkable family of geometric forms that came to be known as Penrose tiles. He even moonlighted as a brain researcher, coming up with a provocative theory that consciousness arises from quantum-mechanical processes. And he wrote a series of incredibly readable, best-selling science books to boot. And yet the 78-year-old Penrose—now an emeritus professor at the Mathematical Institute, University of Oxford—seems to live the humble life of a researcher just getting started in his career. His small office is cramped...

The artist M. C. Escher was influenced by your geometric inventions. What was the story there?

You have called the real-world implications of quantum physics nonsensical. What is your objection? Quantum mechanics is an incredible theory that explains all sorts of things that couldn’t be explained before, starting with the stability of atoms.

Correct me if I am wrong, but he doesn't have a "theory" (collection of evidence by positive observations of predictions made by a hypothesis) of consciousness but merely an assumption or rather a desire that there has to be more to it than most people think.

No (well yes), you are not wrong. However Penrose has to a very large extent exposed certain new and quite novel understandings of the workings of math and physics (though I read yrs a go his "emperors new mind" I was not impressed. having said that, he is a thinker that should not be taken lightly. I do think that he intuits towards a more coherent view of entanglement and...

I think everybody is aware that we do not yet have a TOE. I also do not think that we have to take everything serious people with decades of experience and contributions to science say. If he said he was abducted by aliens to meet the first lady of Japan on Venus, I doubt people would just investigate it because it is Penrose who said so. Supposedly as rational acting individuums we should seek substantiation that is on par with a thesis.

the point is not that Penrose is wrong (he most likely is) like Searle, it is the kind of attack on strong AI that he mounts, that demands a thorough (consistent and coherent) theory of mind which we lack at present but we can use some of his arguments (for refutation purposes) to advance our understanding

"Briefly, here is the path of Penrose's proposed revolution. If the brain is a computer, its powers are circumscribed by the limits on all computation uncovered by Turing and Gödel. Turing showed that each possible mechanical computation can be precisely specified by a recipe consisting of a sequence of dead-simple mechanical steps. Such a recipe is called an algorithm; all computer...

The brain is not a a computer. computers are like the brain, in the direction of the brain, (after all they come from applied mind, but developed minds are both rare, and incomplete in their abilities yet) but the brain is merely the physical correlate for the location of consciousness, and that is soooooooo much more subtle than brain, and soooooo much more subtle than any computer metaphor could ever point to ... science has light-years to go

I hate consciousness, leave me alone with it. It's all way too loaded because people create stupid concepts and then look for phenomena that might fit these loose obsessions and if they can't find them they mystify the whole matter for that surely there must be a phenomena that resembles anything someone can conceive.
- Alexander Kruel
And at the end of time if still nobody has found consciousness and free will, it's not that they might simply be bogus desires, it's that we looked in the wrong place. Or it's all much easier than thought because some smart ass redefines consciousness or whatever to mean banana juice.
