Art and Physics

By on April 8, 2013 in News 0

Via orwellwasright:

It’s well known that many of the great breakthroughs in science seem to occur both independently and near-simultaneously: Isaac Newton, Gottfried Leibniz and the development of calculus; Nikola Tesla, Guglielmo Marconi and the invention of the radio; Alfred Russel Wallace, Charles Darwin and the theory of evolution are just three famous examples of radical new theories and inventions appearing in apparent isolation from one another. But what if scientific developments are prefigured by artists, who elucidate new concepts and manners of expressing space, light and time which capture the essence of radical new approaches to theoretical physics years before they actually occur? This is the subject for Leonard Shlain’s fascinating book, Art and Physics.

Shlain takes the reader on a journey through history, from the classical art of the Greco-Roman world through the spiritual mosaics of the medieval era and the Age of Reason up to the present day; from Euclidean geometry to Galileo, Newton and the discoveries of Einstein.… Read the rest

The Universe Does Not Exist: Conspiratorial Cosmology – the Case Against the Universe

By on April 5, 2013 in News 0

From Modern Mythology:

German physicists Jörg P. Rachen and Ute G. Gahlings have recently discovered evidence of a Universal Conspiracy and have just published their results in a brilliant exposé published in the highly esteemed Journal of Comparative Irrelevance:

Abstract: “Based on the cosmological results of the Planck Mission, we show that all parameters describing our Universe within the ΛCDM model can be constructed from a small set of numbers known from conspiracy theory. Our finding is confirmed by recent data from high energy particle physics. This clearly demonstrates that our Universe is a plot initiated an unknown interest group or lodge. We analyse possible scenarios for this conspiracy, and conclude that the belief in the existence of our Universe is an illusion, as previously assumed by ancient philosophers, 20th century science fiction authors and contemporary film makers.

Are Men Doomed To Go Extinct?

By on April 4, 2013 in News 0

The Sydney Morning Herald on evolutionary scientists’ assertion that biological males as we know them are on the way out, due to the inherent flawed nature of the Y chromosome:

The poorly designed Y chromosome that makes men is degrading rapidly and will disappear, even if humans are still around.

Evolutionary geneticist Jenny Graves says that while the process is likely to happen within the next five million years, it could have begun in some isolated groups. Professor Groves, who first made the prediction some years ago, gave a public lecture on the subject for the Australian Academy of Science.

If humans don’t become extinct, new sex-determining genes and chromosomes will evolve, maybe leading to the evolution of new hominid species. “As long as something came along in its stead, we would not even suspect without checking the chromosomes,” she said on Tuesday. This had happened in the Japanese spiny rat, which had survived the loss of its Y.

Can We Patent Life?

By on April 2, 2013 in News 0

An interesting question posed by Michael Specter in The New Yorker‘s new Science & Tech section:

On April 12, 1955, Jonas Salk, who had recently invented the polio vaccine, appeared on the television news show “See It Now” to discuss its impact on American society. Before the vaccine became available, dread of polio was almost as widespread as the disease itself. Hundreds of thousands fell ill, most of them children, many of whom died or were permanently disabled.

The vaccine changed all that, and Edward R. Murrow, the show’s host, asked Salk what seemed to be a reasonable question about such a valuable commodity: “Who owns the patent on this vaccine?” Salk was taken aback. “Well, the people,” he said. “There is no patent. Could you patent the sun?”

The very idea, to Salk, seemed absurd. But that was more than fifty years ago, before the race to mine the human genome turned into the biological Klondike rush of the twenty-first century.

NASA Wants $100 Million To Catch An Asteroid

By on April 1, 2013 in News 0

2007wd5And just what do you think they’ll do with the damn thing if they actually catch it? From Aviation Week:

NASA’s fiscal 2014 budget request will include $100 million for a new mission to find a small asteroid, capture it with a robotic spacecraft and bring it into range of human explorers somewhere in the vicinity of the Moon.

Suggested last year by the Keck Institute for Space Studies at the California Institute of Technology, the idea has attracted favor at NASA and the White House Office of Science and Technology Policy. President Obama’s goal of sending astronauts to a near-Earth asteroid by 2025 can’t be done with foreseeable civil-space spending, the thinking goes. But by moving an asteroid to cislunar space — a high lunar orbit or the second Earth-Moon Lagrangian Point (EML2), above the Moon’s far side — it is conceivable that technically the deadline could be met.

Trees Used to Create Recyclable, Efficient Solar Cell

By on March 31, 2013 in News 0

Via ScienceDaily:

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.The technology is published in the journal Scientific Reports, the latest open-access journal from the Nature Publishing Group.

The researchers report that the organic solar cells reach a power conversion efficiency of 2.7 percent, an unprecedented figure for cells on substrates derived from renewable raw materials. The CNC substrates on which the solar cells are fabricated are optically transparent, enabling light to pass through them before being absorbed by a very thin layer of an organic semiconductor. During the recycling process, the solar cells are simply immersed in water at room temperature. Within only minutes, the CNC substrate dissolves and the solar cell can be separated easily into its major components.

DMT Discovered in Marine Sponges

By on March 29, 2013 in News 0

Some people have all the luck. Some people get excited when they win a free order of fries and that’s the best they get. Not my pal, Hamilton Morris. No, he gets things like newly discovered variations of DMT. Before some of you get all huffy with your hours of arguments, just remember that this is scientific work on the cutting edge. Though it is controversial to some, an understanding of what we call consciousness is serious business to people like Hamilton.

That said, check out this astonishing article at Vice.com.

Modest though it may be, what we have contained in this letter is possible evidence of the first psychedelic drug of marine origin.1 In 1997 Alexander Shulgin wrote of marine tryptamines, “5-Bromo-DMT and 5,6-dibromo-DMT are found in the sponges Smenospongia aurea and S. echina resp. I have no idea if they are active by smoking (the 5-Br-DMT just might be)… I had the fantasy of trying to scotch the rumor I’m about to start, that all the hippies of the San Francisco Bay Area were heading to the Caribbean with packets of Zig-Zag papers, to hit the sponge trade with a psychedelic fervor.

The Postmortem Portraits of Phineas Gage

By on March 24, 2013 in News 0

Picture: John Darrell Van Horn (C)

Vaughan Bell writes at Mind Hacks:

A new artform has emerged – the post-mortem neuroportrait. Its finest subject, Phineas Gage.

Gage was a worker extending the tracks of the great railways and suffered the most spectacular injury. As he was setting a gunpowder charge in a rock with a large tamping iron, the powder was lit by an accidental spark. The iron was launched through his skull.

He became famous in neuroscience because he lived – rare for the time – and had psychological changes as a result of his neurological damage.

His story has been better told elsewhere but the interest has not died – studies on Gage’s injury have continued to the present day.

There is a scientific veneer, of course, but it’s clear that the fascination with the freak Phineas has its own morbid undercurrents.

The image is key.

The first such picture was constructed with nothing more than pen and ink.

The Dark Secrets of Medicine–Revealed in a New Series!

By on March 24, 2013 in News 0

Imagine, if you will, a low stone slab. Upon it, dimly lit and un-preserved, is a three-day-old corpse going slowing rancid in warm the summer night. This, young surgeon, is your textbook. If you are lucky. For many a medical student, the remains were less fresh, less available (and occasionally less human) than the one I have described. In the 16th century, Andreas Vesalius–the father of anatomy–had to steal half-rotten bodies from the gibbet after hanging. Not what you expect, perhaps, of the profession that has since risen to be one of the most well-respected and well-paid in medicine; long years were spent in the dark before surgeons (and surgery) entered the light.

What happened in this shadowy period is the subject of myth, mystery, mayhem and history–and all of it is rendered in fascinating detail by a new documentary project: Medicine’s Dark Secrets, brought to you by the indefatigable Chirurgeon’s Apprentice: Dr.… Read the rest
