New Brain Theory Required To date, there hasn't been an overarching theory of how the human brain really works, Jeff Hawkins argues in this compelling talk. That's because we still haven't defined intelligence accurately. But one thing's for sure, he says: The brain isn't like a powerful computer processor. It's more like a memory system that records everything we experience and helps us predict, intelligently, what will happen next. Jeff Hawkins - 20 min

An Atheist's Call To Arms The session was titled "The Design of Life," and the TED audience was probably expecting remarks about evolution's role in our history from biologist Richard Dawkins. Instead, he launched into a full-on appeal for atheists to make public their beliefs and to aggressively fight the incursion of religion into politics and education. Richard Dawkins - 30 min

Global Warming Hokum? These people [the IPCC - the International Panel on Climate Change] are openly declaring that they are going to commit scientific misconduct that will be paid for by the United Nations. If they find an error in the summary, they won’t fix it. Instead, they will ‘adjust’ the technical report so that it looks consistent. Melanie Phillips

George Bush's Stem Cell Fiasco When George Bush banned funding he effectively put researchers into quarantine. Ed Pilkington

The Strangeness Of Science - Video Lecture By Richard Dawkins Richard Dawkins is Oxford University's "Professor for the Public Understanding of Science" suggests that the true nature of the universe eludes us, because the human mind evolved only to understand the "middle-sized" world we can observe.

The Goldilocks Enigma Professor Paul Davies' The Goldilocks Enigma tackles fundamental questions about the nature of the universe and our attempts to understand it. Scientific breakthroughs, he argues, have brought us to the brink of comprehending the underlying structure of nature or "a final 'theory of everything'".

Climate Change Deniers Demonised ‘The beauty of science is that no issue is ever “settled”, that no question is beyond being more fully understood, that no conclusion is immune to further experimentation. And yet for the first time in history, the Royal Society is shamelessly using the media to say emphatically: “case closed” on all issues related to climate change.’ Brendan O'Neill - 5 min

The God Delusion In The God Delusion, the scientist Richard Dawkins sets out to attack God "in all his forms". - with 10-minute video of Jeremy Paxman interviewing Richard Dawkins.

Evolution Is Losing? Evolution is losing the battle, says Ruse, and it's the fault of Dawkins and Dennett with their aggressive atheism: they are the creationists' best recruiting sergeants. Madeleine Bunting

Future Science Science will continue to surprise us with what it discovers and creates; then it will astound us by devising new methods to surprises us. At the core of science's self-modification is technology. New tools enable new structures of knowledge and new ways of discovery. The achievement of science is to know new things; the evolution of science is to know them in new ways. What evolves is less the body of what we know and more the nature of our knowing. Kevin Kelly - 9 min

The Most Beautiful Experiments Robert P. Crease, a member of the philosophy department at the State University of New York at Stony Brook and the historian at Brookhaven National Laboratory, recently asked physicists to nominate the most beautiful experiment of all time. 

Beware Design Accepting 'intelligent design' in science classrooms would have disastrous consequences. Richard Dawkins and Jerry Coyne - 6 min

In Defence Of Common Sense Scientists' contempt for common sense has two unfortunate implications. One is that preposterousness, far from being a problem for a theory, is a measure of its profundity; hence the appeal, perhaps, of dubious propositions like multiple-personality disorders and multiple-universe theories. The other, even more insidious implication is that only scientists are really qualified to judge the work of other scientists. John Horgan - with comments from others - 9 min

Biocomputation Biologist J. Craig Venter once raced the U.S. government to complete the decoding of the human genome. Now, after a maverick career studying the code of life, Dr. Venter has a new goal: life itself. J. Craig Venter, Ray Kurzweil, Rodney Brooks - 40 min

Along with two veteran collaborators, Dr. Venter hopes to become the first to whip up a made-to-order bacterium. Normally, new life is created via reproduction, with each generation passing its genes on to the next. But Dr. Venter aims to bypass that process by manufacturing a complete set of genes, or genome, of a single-cell bacterium in his laboratory. This man-made genome would be installed inside a bacterium whose own genes have been removed.

By creating such a life form, Dr. Venter's researchers think they may come closer to understanding what life is and how scientists can manipulate it for the benefit of humankind. New artificial species could open avenues for industrial production of drugs, chemicals or clean energy.

Good Reasons To Shrink The Size Of The Moon We all love the large, pale moon that hangs in our nighttime sky. A half-sized blue and green one will definitely take some getting used to, especially when its dark side starts lighting up with cities. Still, the prospect of a new world—large enough to house the entire United States, accessible enough to serve as the airline hub for an entire solar system, and yet safe enough to survive a technological collapse—may be too good to pass up. Wil McCarthy - 6 min

Psychic Hotlines Those corporations were making millions and millions of dollars. They had more than 1,000 psychics working for them. The psychics were paid 15 cents for every minute they were on the phone, while callers were being charged $3.95 a minute. Dougall Fraser - 5 min

Are We Alone? Science has helped answer some of the fundamental questions of our existence. Yet, as Paul Davies reminds us, we are still a long way from solving perhaps the most intriguing mystery of all: Are we alone in the universe? Marianna Krejci-Papa interviews Paul Davies - 7 min

Argument From Improbability Carl Sagan said: "Extraordinary claims require extraordinary evidence. Dr. Craig has made the extraordinary claim that certain empirical facts require supernatural explanations. Vic Stenger

Mind And Medicine A third test involved telling subjects they would be tested with two types of cream: one would reduce pain and the other would not. The test subjects reported that the cream worked as promised and this was confirmed by scans of their brains. Of course, the “two” creams were the same. Michael LaBossiere - 4 min

String Theory I find myself spending most of my time staring out the window. I see blocks of equations dancing in my head, and I spend hours trying to fit them together. These blocks are as familiar to me as the back of my hand, and I spend much of my waking time turning them inside out in my head. Michio Kaku - 8 min

The Fossil Fallacy We know evolution happened because of the convergence of evidence from such diverse fields as geology, paleontology, biogeography, comparative anatomy and physiology, molecular biology, genetics, and many more. Michael Shermer  

Human Intelligence Might Be Unique Despite the lack of evidence to support the existence of extraterrestrial intelligence, many people firmly believe in it. If you are skeptical on this matter you are likely to be accused of being arrogant, anthropocentric or even a religious fanatic. However, to consider the possibility that we might be alone in the universe doesn’t necessarily make you any of those things. You can believe both that humans are rare or unique and at the same time that they are a purposeless arrangement of matter or a curious accident in space-time. Paula Bourges-Waldegg - 5 min

We Are All Mutants These days anthropologists and geneticists overwhelmingly emphasise the similarities among people from different parts of the world at the expense of the differences. From a political point of view I have no doubt that's a fine thing. But I suggest that it's time that we grew up. I would like to suggest that actually by emphasizing the similarities but ignoring the differences, we are turning away from one of the most beautiful problems that modern biology has left: namely, what is the genetic basis of the normal variety of differences between us? Armand Leroi - followed by responses from various learned folk - 30 min

Limit To Size Of Stars? Unlike humans, stars are born with all the weight they will ever have. Although astronomers know that stars come in a variety of masses, they are still stumped when it comes to figuring out if stars have a weight limit at birth. 5 min

Synaesthesia When Ingrid Carey says she feels colors, she does not mean she sees red, or feels blue, or is green with envy. She really does feel them. 

Cut Out The Bio-Hype A common and disturbing feature of the ubiquitous bioethical commentaries is the short shrift—often, complete inattention—given to the feasibility of the technologies under discussion. ... What is especially disturbing is that, on occasion, even when the failure of the procedure or technology is known and clearly documented, commentators have continued to talk on about ethical issues as though the science will still, somehow, inexorably succeed. Ruth Levy Guyer and Jonathan Moreno - 10 min 

Interview With Sir Martin Rees Some people imagine that there will be humans watching the sun's demise six billion years from now, but any creatures that exist then will be as different from us now as we are from bacteria or amoebae. Part I - out of three Parts - 10 min in total

Human Animal Hybrids Let's say you need a new liver. Zanjani would take some of your bone marrow stem cells, and inject them into a fetal sheep at the proper moment. A few weeks later the lamb would be born with a liver made up chiefly of your cells. The lamb would be sacrificed and your new liver installed. Once installed, your immune system would eliminate the lamb's liver cells, leaving behind a brand new organ perfectly matched to your body. Ronald Bailey
