Photograph: Simon Payne&lt;br&gt;&lt;br&gt;A race is on against the fast pace of technological change as &lt;br&gt;scientists search for ways to preserve today's most innovative artworks.&lt;br&gt;&lt;br&gt;A team of experts is warning that some of Britain's contemporary &lt;br&gt;artistic landmarks will be no more than memories within a decade &lt;br&gt;unless conservationists can effectively archive digital works and &lt;br&gt;stop them degrading.&lt;br&gt;&lt;br&gt;"The threat is very real that, unless we do something, we will have a &lt;br&gt;'lost generation' in terms of our cultural heritage," said Dr David &lt;br&gt;Anderson, who, together with his colleague Dr Janet Delve at the &lt;br&gt;School of Creative Technologies at the University of Portsmouth, is &lt;br&gt;leading efforts to save the more complex artworks of the digital age &lt;br&gt;from oblivion.&lt;br&gt;&lt;br&gt;"Past generations captured who they were and what they did via &lt;br&gt;museums and books," Anderson said, "but the pace of technological &lt;br&gt;development in the digital age has now outstripped our capacity for &lt;br&gt;preservation."&lt;br&gt;&lt;br&gt;At the same time as the visual artist &lt;br&gt;Hilary Lloyd is &lt;br&gt;nominated for this year's Turner Prize for her inventive work in film &lt;br&gt;and video, "digital preservationists" are campaigning for more shared &lt;br&gt;research and have organized the first of a series of symposiums to be &lt;br&gt;held at King's College London and Cambridge next month.&lt;br&gt;&lt;br&gt;The fast pace by which technology changes means that many of the &lt;br&gt;earliest works of art created on computer are in danger of being &lt;br&gt;lost, or are already impossible to read, while new interactive &lt;br&gt;digital artworks, such as visualizations and video games, are so &lt;br&gt;complex that scientists are not yet capable of faithfully preserving them.&lt;br&gt;&lt;br&gt;"Digital preservation is desperately important," said Anderson. "In &lt;br&gt;technology little things change all the time. Over the course of a &lt;br&gt;20- or 30-year working life, the software we use is updated or made &lt;br&gt;obsolete all the time, but most of us aren't really bothered by the &lt;br&gt;changes. But in terms of science and art, digital preservation is &lt;br&gt;increasingly important."&lt;br&gt;&lt;br&gt;Preserving today's works of art poses more of a challenge to science &lt;br&gt;than continued efforts to restore and conserve the great oil &lt;br&gt;paintings and sculptures of the past, Anderson and Delve argue.&lt;br&gt;&lt;br&gt;It is a problem already faced by collectors and contemporary art &lt;br&gt;galleries, as formats are updated and CDs, DVDs and digital recordings degrade.&lt;br&gt;&lt;br&gt;Lloyd, 48, from Halifax, creates innovative work that poses typical &lt;br&gt;problems for conservators. Her recent film and video footage, &lt;br&gt;previously on display at the Raven Row gallery in London, was put &lt;br&gt;together in a way that subverts expectations of art. A piece that &lt;br&gt;initially appeared to be a still life, for example, turned out to be &lt;br&gt;in perpetual motion. Projectors and monitors formed a part of the work itself.&lt;br&gt;&lt;br&gt;"In digital art, the key is to find ways of preserving the colour and &lt;br&gt;visual aspects of a piece of art. If we don't preserve the digital &lt;br&gt;art made today, it could be like walking into a world-famous gallery &lt;br&gt;and seeing nothing on the walls, that no art has survived some global &lt;br&gt;meltdown," said Anderson.&lt;br&gt;&lt;br&gt;A new digital art gallery is to launch on Monday in the centre of &lt;br&gt;Cambridge. The vaulted section, set up by Anglia Ruskin University &lt;br&gt;inside the Ruskin Gallery, which was opened by the art critic John &lt;br&gt;Ruskin in 1858, has been fitted with cutting-edge  plasma screens &lt;br&gt;to enable digital artists to experiment.&lt;br&gt;&lt;br&gt;But the preservation of this kind of work, in contrast, is still a &lt;br&gt;work in progress.&lt;br&gt;&lt;br&gt;Dr Simon Payne, a &lt;br&gt;digital video &lt;br&gt;artist and senior lecturer in film and media at Anglia Ruskin &lt;br&gt;University, who will be exhibiting at the gallery, points out that &lt;br&gt;many contemporary artists are happy for their work to have a short &lt;br&gt;lifespan, or at least can accept that its temporary nature is a key &lt;br&gt;part of the experience for viewers.&lt;br&gt;&lt;br&gt;"Some artists who make digital art that is ephemeral, who are almost &lt;br&gt;like performance artists, are dedicated to the idea that it will not last.&lt;br&gt;&lt;br&gt;"But from an academic point of view, of course, you want to be able &lt;br&gt;to recreate the culture of the past and to show it to students."&lt;br&gt;&lt;br&gt;Payne's own work is what he describes as "perceptual", playing with &lt;br&gt;what the viewer can see, such as the Op Art movement of the 60s and 70s.&lt;br&gt;&lt;br&gt;"It is designed with the idea of creating a discrete physical effect &lt;br&gt;on the viewer and for me, ideally, it should be shown in the context &lt;br&gt;of a cinema, so I don't know how you would ever preserve it effectively."&lt;br&gt;&lt;br&gt;Ironically, an artwork made or recorded on celluloid, or even on &lt;br&gt;videotape, is more likely to survive the test of time than more &lt;br&gt;recent work created or archived digitally, Payne added.&lt;br&gt;&lt;img src="http://images.quickblogcast.com/2/5/5/3/1/121623-113552/44ccf4f.jpg" alt=""&gt;</description><category>FYI</category><comments>http://blog.barclaye.net/2011/05/09/race-to-save-digital-art-from-the-rapid-pace-of-technological-change.aspx#Comments</comments><guid isPermaLink="false">81d4a915-8f12-47b3-a70a-d84d476ea243</guid><pubDate>Mon, 09 May 2011 20:02:00 GMT</pubDate></item><item><title>Albert Einstein was right, say scientists, 100 years on</title><link>http://blog.barclaye.net/2011/05/09/albert-einstein-was-right-say-scientists-100-years-on.aspx?ref=rss</link><author>j06martinbrown@gmail.com (J deBruin)</author><description>&lt;br&gt;&lt;br&gt;Albert Einstein was right, say scientists, 100 years on&lt;br&gt;&lt;br&gt;The theory of general relativity is as relevant &lt;br&gt;to us today as it was when it was formulated, as &lt;br&gt;a discovery about space-time reveals&lt;br&gt;&lt;br&gt;&lt;br&gt;After working for half a century and spending &lt;br&gt;Â£500m, scientists last week revealed that they &lt;br&gt;have detected strange fluctuations in Earth's &lt;br&gt;orbit. &lt;br&gt;Space-time &lt;br&gt;is bent and then twisted round our planet as it &lt;br&gt;rotates, announced researchers with Nasa's Gravity Probe B project.&lt;br&gt;&lt;br&gt;The effect is tiny but crucial, they added Â– and &lt;br&gt;was predicted almost 100 years ago by &lt;br&gt;Albert &lt;br&gt;Einstein in his great theory of gravity, general &lt;br&gt;relativity. According to Einstein, an apple falls &lt;br&gt;to the ground not because it feels the force of &lt;br&gt;Earth's gravity but because the apple is &lt;br&gt;responding to the curvature of space-time near &lt;br&gt;the Earth's surface caused by the planet's huge &lt;br&gt;mass. In the same way, the Sun bends space in a &lt;br&gt;manner that allows Earth to revolve around it.&lt;br&gt;&lt;br&gt;Crucially, the theory raised a host of other &lt;br&gt;predictions that scientists have been confirming &lt;br&gt;for the past century. The findings of Gravity &lt;br&gt;Probe B are the latest in a long list of these &lt;br&gt;many vindications of Einstein's genius and reveal &lt;br&gt;how his great theory touches our lives in unexpected ways.&lt;br&gt;&lt;br&gt;"We have completed this landmark experiment of &lt;br&gt;testing Einstein's universe," said project leader &lt;br&gt;Francis Everitt, of Stanford University. "And Einstein survives."&lt;br&gt;&lt;br&gt;Everitt began work on Gravity Probe B in 1962 and &lt;br&gt;has worked on nothing else since, although he had &lt;br&gt;many close shaves, with the satellite being &lt;br&gt;cancelled and then revived on seven occasions &lt;br&gt;before it was eventually launched in 2004. Then, &lt;br&gt;after the probe reached orbit, spurious &lt;br&gt;electrical signals were found to be distorting &lt;br&gt;data that it had sent back. It took five years' &lt;br&gt;study before scientists found how to extract clean data from it.&lt;br&gt;&lt;br&gt;Results of the analyses of this data were &lt;br&gt;revealed last week. They showed that Earth does &lt;br&gt;indeed bend space-time. It was also found that, &lt;br&gt;as our planet rotates, it drags space-time with &lt;br&gt;it Â– a phenomenon known as frame-dragging. The &lt;br&gt;effect is like spinning a spoon in a cup of tea, &lt;br&gt;causing the liquid to start swirling round inside the cup.&lt;br&gt;&lt;br&gt;These phenomena are tiny, it should be noted. In &lt;br&gt;the case of frame-dragging, space around Earth &lt;br&gt;turns at a rate of 37 one-thousandths of a second &lt;br&gt;every year because our planet pulls it round as &lt;br&gt;it revolves Â– a rate predicted by Einstein.&lt;br&gt;&lt;br&gt;"The probe's results are a great achievement, but &lt;br&gt;we should not think of them as a new proof that &lt;br&gt;general relativity is right," said Graham &lt;br&gt;Farmelo, physicist and author. "Einstein was &lt;br&gt;shown to be correct long ago, only a few years &lt;br&gt;after he came up with the theory. However, we are &lt;br&gt;still testing out all its predictions. The &lt;br&gt;results from Gravity Probe B are just the most recent, successful outcomes."&lt;br&gt;&lt;br&gt;In fact, the premise of Einstein's theory of &lt;br&gt;general relativity was proved within three years &lt;br&gt;of its publication in 1916. British astronomer &lt;br&gt;Arthur Eddington was involved in an expedition to &lt;br&gt;PrÃ­ncipe island in west Africa, where he &lt;br&gt;photographed the total solar eclipse of 1919. The &lt;br&gt;photographs showed that the positions of stars &lt;br&gt;whose light rays passed near the Sun appeared to &lt;br&gt;have been slightly shifted because their light &lt;br&gt;had been curved by the Sun's huge gravitational &lt;br&gt;field. This was noticeable only during an eclipse &lt;br&gt;because the Sun's brightness would otherwise obscure the affected stars.&lt;br&gt;&lt;br&gt;"Eddington presented these as a triumph for &lt;br&gt;general relativity, and Einstein, who was known &lt;br&gt;to physicists but not the public, became a star overnight," said Farmelo.&lt;br&gt;&lt;br&gt;For his part, Einstein never had any doubts that &lt;br&gt;he was right. When asked how he would have &lt;br&gt;reacted if Eddington's observations had disproved &lt;br&gt;his theory, he replied: "I would have felt sorry &lt;br&gt;for the dear Lord. The theory is correct."&lt;br&gt;&lt;br&gt;Since then, scientists have produced many other &lt;br&gt;confirmations. One example was provided by US &lt;br&gt;astronomers Russell Hulse and John Taylor, who &lt;br&gt;discovered two dense collapsed stars, known as &lt;br&gt;neutron stars, that were in orbit around each &lt;br&gt;other and that were losing energy that could only &lt;br&gt;be explained through the gravitational radiation, &lt;br&gt;another phenomenon predicted by Einstein. In 1993 &lt;br&gt;Hulse and Taylor were awarded that year's Nobel &lt;br&gt;prize for physics.&lt;br&gt;&lt;br&gt;"General relativity touches our lives in many &lt;br&gt;unexpected ways," added physicist Dr Charles &lt;br&gt;Wang, of Aberdeen University. "Another effect &lt;br&gt;that is predicted by general relativity is the &lt;br&gt;phenomenon known as gravitational time dilation. &lt;br&gt;This states that time slows down as gravitational &lt;br&gt;strength increases, a fact that has been &lt;br&gt;confirmed by GPS satellites. These carry atomic &lt;br&gt;clocks that have to run at a different speed to &lt;br&gt;those on the ground because gravity is greater &lt;br&gt;there. If you didn't, the world's GPS system would break down."&lt;br&gt;&lt;br&gt;"Einstein's theory of general relativity is one &lt;br&gt;of the most beautiful pieces of scientific work &lt;br&gt;in history," added Farmelo. "But it is not the &lt;br&gt;whole story. It explains how massive objects &lt;br&gt;affect space and time, but it tells us little &lt;br&gt;about how very small sub-atomic particles behave."&lt;br&gt;&lt;br&gt;This point was acknowledged by Wang. "We still &lt;br&gt;have to test how gravity behaves at a sub-atomic, &lt;br&gt;quantum level," he said. "We hope to do that with &lt;br&gt;a project called the Space-Time Explorer Quest, &lt;br&gt;which the European Space Agency is now studying."&lt;br&gt;&lt;br&gt;Together with Wang's group, scientists at &lt;br&gt;Birmingham, the Rutherford-Appleton Laboratory &lt;br&gt;and the National Physical Laboratory, along with &lt;br&gt;German researchers, have proposed building a &lt;br&gt;probe that would use caesium or rubidium atoms, &lt;br&gt;cooled close to absolute zero, to test the effect &lt;br&gt;of gravity at the sub-atomic level and, they &lt;br&gt;hope, provide data that could reconcile relativity and quantum theory.&lt;br&gt;&lt;br&gt;"That won't be for another 10 years or more," &lt;br&gt;said Wang. "That means we are going to have a lot &lt;br&gt;of work to do on general relativity for quite some time."&lt;br&gt;&lt;br&gt;    * guardian.co.uk Â© Guardian News and Media Limited 2011&lt;br&gt;</description><category>FYI</category><comments>http://blog.barclaye.net/2011/05/09/albert-einstein-was-right-say-scientists-100-years-on.aspx#Comments</comments><guid isPermaLink="false">6e742db6-1450-4360-8ceb-6dc0ac8cd482</guid><pubDate>Mon, 09 May 2011 20:01:00 GMT</pubDate></item><item><title>Saturn's Moon Titan May Have Been Planetary Punching Bag</title><link>http://blog.barclaye.net/2011/05/09/saturns-moon-titan-may-have-been-planetary-punching-bag.aspx?ref=rss</link><author>j06martinbrown@gmail.com (J deBruin)</author><description>&lt;br&gt;&lt;br&gt;Saturn's Moon Titan May Have Been Planetary Punching Bag&lt;br&gt;&lt;br&gt;Charles Q.

In fact, the surface pressure on Titan is &lt;br&gt;50 percent greater than the pressure on Earth. &lt;br&gt;[Photos: &lt;br&gt;The Rings and Moons of Saturn]&lt;br&gt;&lt;br&gt;The main ingredient of &lt;br&gt;Titan's &lt;br&gt;atmosphere is nitrogen, just as it is on Earth. Where this nitrogen &lt;br&gt;came from has long been debated. For instance, it could be &lt;br&gt;primordial, accumulating as Titan formed, or it could have originated later.&lt;br&gt;&lt;br&gt;&lt;br&gt;Weighing the options&lt;br&gt;&lt;br&gt;In 2005, the Huygens probe carried by &lt;br&gt;NASA's &lt;br&gt;Cassini spacecraft to Saturn ruled out a primordial origin for this &lt;br&gt;nitrogen. Titan's atmosphere apparently has extremely low levels of &lt;br&gt;the isotope argon-36, while high amounts are expected in an &lt;br&gt;atmosphere rich in primordial nitrogen.&lt;br&gt;&lt;br&gt;There are a number of other explanations for how this atmospheric &lt;br&gt;nitrogen might have formed after Titan's birth. For instance, &lt;br&gt;sunlight in Titan's atmosphere might have broken apart ammonia, a &lt;br&gt;molecule made of nitrogen and hydrogen.&lt;br&gt;&lt;br&gt;However, nearly all these suggestions require that Titan formed at &lt;br&gt;relatively high temperatures, which would have led the moon to &lt;br&gt;differentiate into a rocky core and an icy mantle layer, and &lt;br&gt;Cassini's radar scans suggested that Titan is not fully &lt;br&gt;differentiated. Comets loaded with nitrogen might have delivered it &lt;br&gt;to Titan, but that would have also led to higher levels of argon-36 &lt;br&gt;than currently seen.&lt;br&gt;&lt;br&gt;Now scientists in Japan suggest that countless numbers of &lt;br&gt;asteroids &lt;br&gt;and comets slamming into ammonia ice on Titan could have converted it &lt;br&gt;to nitrogen gas several hundred million years after the moon's formation.&lt;br&gt;&lt;br&gt;"Our results suggest that hypervelocity impacts have played a key &lt;br&gt;role," researcher Yasuhito Sekine, a planetary scientist at the &lt;br&gt;University of Tokyo, told SPACE.com.&lt;br&gt;&lt;br&gt;Solar system dodgeball&lt;br&gt;&lt;br&gt;During an era known as the Late Heavy Bombardment about four billion &lt;br&gt;years ago, the solar system was very much like a shooting gallery, &lt;br&gt;with cosmic impacts regularly blasting planets and moons. To see if &lt;br&gt;such impacts would deliver enough energy to convert ammonia ice to &lt;br&gt;nitrogen, researchers used laser guns and "bullets" made of gold, &lt;br&gt;platinum or copper foil. The beams vaporized the back of these &lt;br&gt;bullets, propelling them at high speeds at targets made of ammonia &lt;br&gt;and water ice.&lt;br&gt;&lt;br&gt;The researchers found "ammonia is very easily converted to nitrogen &lt;br&gt;molecule by impacts," Sekine said.&lt;br&gt;&lt;br&gt;They calculated that 330 million billion tons (300 million billion &lt;br&gt;metric tons) worth of impactors could have produced the current &lt;br&gt;amount of nitrogen seen on Titan, "a plausible mass of impactors &lt;br&gt;during the Late Heavy Bombardment," noted planetary scientist &lt;br&gt;Catherine Neish at Johns Hopkins University, who did not take part in &lt;br&gt;this research.&lt;br&gt;&lt;br&gt;"It's an interesting new hypothesis," Neish told SPACE.com. &lt;br&gt;"Differentiating between the different hypotheses will require a more &lt;br&gt;detailed understanding of Titan's internal structure, and the &lt;br&gt;composition of comets and-or other Saturnian satellites." She &lt;br&gt;suggested that a future mission to a comet would very likely provide &lt;br&gt;key evidence to help confirm or refute the idea.&lt;br&gt;&lt;br&gt;One question would be where all the craters from such impacts might &lt;br&gt;be. Titan has only about 50 recognized craters, Neish said. "Does &lt;br&gt;this imply that Titan's surface is very young?" she asked, suggesting &lt;br&gt;a young surface could have covered up most of the &lt;br&gt;craters &lt;br&gt;on Titan.&lt;br&gt;&lt;br&gt;The scientists detailed their findings online May 8 in the journal &lt;br&gt;Nature Geoscience.&lt;br&gt;&lt;br&gt;Follow SPACE.com contributor Charles Q.

Can it create a new generation of conservationists?&lt;br&gt;Leo Blog : leafsnap mobile phone app&lt;br&gt;&lt;br&gt;Screengrab of Leafsnap mobile phone app. Photograph: leafsnap.com&lt;br&gt;&lt;br&gt;To date, the world of mobile phone apps has &lt;br&gt;largely left me cold. Yes, I can see how you can &lt;br&gt;easily lose an hour of your life Â– or more Â– to &lt;br&gt;Angry &lt;br&gt;Birds. But the most interesting and potentially &lt;br&gt;useful developments I have seen so far are apps &lt;br&gt;such as Shazam and &lt;br&gt;RedLaser. The power to &lt;br&gt;identify and recognise non-text based things such &lt;br&gt;as images and music points to just how potent and &lt;br&gt;useful &lt;br&gt;mobile phones are becoming.&lt;br&gt;&lt;br&gt;It now appears that we could be about to reach a &lt;br&gt;significant new landmark. An app has just been &lt;br&gt;launched that can identify a species of tree from &lt;br&gt;a photograph of its leaf. Apps exist already that &lt;br&gt;help you identify flora and fauna Â– the Forestry &lt;br&gt;Commission recently launched an app called &lt;br&gt;ForestXplorer &lt;br&gt;for identifying trees Â– but they have &lt;br&gt;traditionally relied on the user deducing the &lt;br&gt;species from a list of possible characteristics.&lt;br&gt;&lt;br&gt;Leafsnap promises something &lt;br&gt;different: a joint effort by &lt;br&gt;Columbia &lt;br&gt;University, the &lt;br&gt;University of &lt;br&gt;Maryland, and the &lt;br&gt;Smithsonian &lt;br&gt;Institution in the US, it uses the same &lt;br&gt;technology as face-recognition software to identity the species itself:&lt;br&gt;&lt;br&gt;This free mobile app helps identify tree species &lt;br&gt;from photographs of their leaves and contains &lt;br&gt;beautiful high-resolution images of their &lt;br&gt;flowers, fruit, petiole, seeds, and bark. &lt;br&gt;Leafsnap currently includes the trees of New York &lt;br&gt;City and Washington, D.C., and will soon grow to &lt;br&gt;cover the trees of the entire continental United States.&lt;br&gt;Leafsnap turns users into citizen scientists, &lt;br&gt;automatically sharing images, species &lt;br&gt;identifications, and geo-coded stamps of species &lt;br&gt;locations with a community of scientists who will &lt;br&gt;use the stream of data to map and monitor the ebb and flow of flora nationwide.&lt;br&gt;The Leafsnap family of electronic field guides &lt;br&gt;aims to leverage digital applications and mobile &lt;br&gt;devices to build an ever-greater awareness of and &lt;br&gt;appreciation for biodiversity.&lt;br&gt;&lt;br&gt;Personally, I think this is a tremendously &lt;br&gt;exciting development. Just think what species &lt;br&gt;recognition software could be next: edible fungi; &lt;br&gt;rock-pool inhabitants; butterflies; wild flowers; &lt;br&gt;the list is endless. Couple this with the app's &lt;br&gt;"geo-coding" potential and it could help to &lt;br&gt;generate some very powerful data. (Please do &lt;br&gt;share below any "nature-spotting" apps you have found particularly useful.)&lt;br&gt;&lt;br&gt;There is a slight lament to note, though. As a &lt;br&gt;child, I used to enjoy flicking through &lt;br&gt;wildlife &lt;br&gt;pocket guides trying to identify species when out &lt;br&gt;on long walks, or on the beach. I wonder what &lt;br&gt;impact this software will have on children today &lt;br&gt;when they know they can identify something within &lt;br&gt;a matter of a few seconds without any real effort &lt;br&gt;or engagement? Will that help to educate and &lt;br&gt;inspire them? Or, conversely, will it tune them &lt;br&gt;into things they might have otherwise simply ignored?&lt;br&gt;    *&lt;br&gt;    * guardian.co.uk Â© Guardian News and Media Limited 2011&lt;br&gt;&lt;img src="http://images.quickblogcast.com/2/5/5/3/1/121623-113552/46ececd.jpg" alt=""&gt;&lt;img src="http://images.quickblogcast.com/2/5/5/3/1/121623-113552/46ecebe.jpg" alt=""&gt;</description><category>FYI</category><comments>http://blog.barclaye.net/2011/05/09/the-mobile-phone-app-that-can-identify-a-tree-by-its-leaf.aspx#Comments</comments><guid isPermaLink="false">123215a0-c6ce-421e-a01d-d6554515c4ea</guid><pubDate>Mon, 09 May 2011 19:58:00 GMT</pubDate></item><item><title>Beamer's Conservation Area</title><link>http://blog.barclaye.net/2011/04/16/beamers-conservation-area.aspx?ref=rss</link><author>j06martinbrown@gmail.com (J deBruin)</author><description>&lt;font style="font-size: 14px;"&gt;&lt;br&gt;    The following is a picture of the protective barrier at upper Beamer's falls.

&lt;b&gt;Beamer's Memorial Conservation Area&lt;/b&gt; is located in Grimsby Ontario, Canada. It is home to many wildlife, especially birds. The following pictures are those of turkey vultures. The birds ride on the updrafts, that are created from the Valley below along the Niagara escarpment.&lt;br&gt;&lt;br&gt;&lt;br&gt;
