  • Oops: Chief Climategate investigator failed to declare eco directorship by Andrew Orlowski, The Register

    Article Tags: Andrew Orlowski

    ‘Dracula’s in charge of the blood bank’

    Exclusive The peer leading the second Climategate enquiry at the University of East Anglia serves as a director of one of the most powerful environmental networks in the world, according to Companies House documents – and has failed to declare it.

    Lord Oxburgh, a geologist by training and the former scientific advisor to the Ministry of Defence, was appointed to lead the enquiry into the scientific aspects of the Climategate scandal on Monday. But Oxburgh is also a director of GLOBE, the Global Legislators Organisation for a Balanced Environment.

    GLOBE may be too obscure to merit its own Wikipedia entry, but that belies its wealth and influence. It funds meetings for parliamentarians worldwide with an interest in climate change, and prior to the Copenhagen Summit GLOBE issued guidelines (pdf) for legislators. Little expense is spared: in one year alone, one peer – Lord Michael Jay of Ewelme – enjoyed seven club class flights and hotel accommodation, at GLOBE’s expense. There’s no greater love a Parliamentarian can give to the global warming cause. And in return, Globe lists Oxburgh as one of 23 key legislators.

  • Mysterious Stone Spheres in Costa Rica Investigated





    A lot has been made of the stone balls down in Costa Rica.  This item blows away the cobwebs and idle speculation surrounding these cultural objects.
    Yes, they could have been made anytime by the Stone Age cultures in which they are embedded.  That they were made by them is fairly certain because the method is pure stone age.  They were kept in their cultural settings with the usual surrounding trash.
    It is easy to imagine a cultural imperative driving their production.  It is as easy to imagine competition between villages that led to larger and larger stone balls.  The small ones may have been movable, but the large ones would never have been moved much distance at all.
    The obvious source rock to use is any convenient erratic dragged out of the mountains by flash floods.  Most are located in a delta region and that somewhat supports that idea.
    This welcome article clearly puts the known facts on the table and allows us to forget the speculation floating around this tale.
    Mysterious Stone Spheres in Costa Rica Investigated

    ScienceDaily (Mar. 23, 2010) — The ancient stone spheres of Costa Rica were made world-famous by the opening sequence of “Raiders of the Lost Ark,” when a mockup of one of the mysterious relics nearly crushed Indiana Jones.

    John Hoopes, University of Kansas associate professor of anthropology and director of the Global Indigenous Nations Studies Program, recently returned from a trip to Costa Rica where he and colleagues evaluated ancient stone spheres for UNESCO, the United Nations cultural organization that might grant the spheres World Heritage Status.

    So perhaps John Hoopes is the closest thing at the University of Kansas to the movie action hero.
    Hoopes, associate professor of anthropology and director of the Global Indigenous Nations Studies Program, recently returned from a trip to Costa Rica where he and colleagues evaluated the stone balls for UNESCO, the United Nations cultural organization that might grant the spheres World Heritage Status.
    His report will help determine if sites linked to the massive orbs will be designated for preservation and promotion because of their “outstanding value to humanity.”
    Hoopes, who researches ancient cultures of Central and South America, is one of the world’s foremost experts on the Costa Rican spheres. He explained that although the stone spheres are very old, international interest in them is still growing.
    “The earliest reports of the stones come from the late 19th century, but they weren’t really reported scientifically until the 1930s — so they’re a relatively recent discovery,” Hoopes said. “They remained unknown until the United Fruit Company began clearing land for banana plantations in southern Costa Rica.”
    According to Hoopes, around 300 balls are known to exist, with the largest weighing 16 tons and measuring eight feet in diameter. Many of these are clustered in Costa Rica‘s Diquis Delta region. Some remain pristine in the original places of discovery, but many others have been relocated or damaged due to erosion, fires and vandalism.
    The KU researcher said that scientists believe the stones were first created around 600 A.D., with most dating to after 1,000 A.D. but before the Spanish conquest.
    “We date the spheres by pottery styles and radiocarbon dates associated with archeological deposits found with the stone spheres,” Hoopes said. “One of the problems with this methodology is that it tells you the latest use of the sphere but it doesn’t tell you when it was made. These objects can be used for centuries and are still sitting where they are after a thousand years. So it’s very difficult to say exactly when they were made.”
    Speculation and pseudoscience have plagued general understanding of the stone spheres. For instance, publications have claimed that the balls are associated with the “lost” continent of Atlantis. Others have asserted that the balls are navigational aids or relics related to Stonehenge or the massive heads on Easter Island.
    “Myths are really based on a lot of very rampant speculation about imaginary ancient civilizations or visits from extraterrestrials,” Hoopes said.
    In reality, archaeological excavations in the 1940s found the stone balls to be linked with pottery and materials typical of pre-Columbian cultures of southern Costa Rica.
    “We really don’t know why they were made,” Hoopes said. “The people who made them didn’t leave any written records. We’re left to archeological data to try to reconstruct the context. The culture of the people who made them became extinct shortly after the Spanish conquest. So, there are no myths or legends or other stories that are told by the indigenous people of Costa Rica about why they made these spheres.”
    Hoopes has a created a popular Web page to knock down some of the misconceptions about the spheres. He said the stones’ creation, while vague, certainly had nothing to do with lost cities or space ships.
    “We think the main technique that was used was pecking and grinding and hammering with stones,” said Hoopes. “There are some spheres that have been found that still have the marks of the blows on them from hammer stones. We think that that’s how they were formed, by hammering on big rocks and sculpting them into a spherical shape.”
  • Fructose Battle Warms Up




    This is early days, but all the ingredients are in place for a national public relations battle aimed at ending the general use of common sugar and high fructose products in the North American diet.  The first shots have been fired and it is a good bet that school kids will shortly be forced to either bring soda pop to school or to buy it outside the school.
    I anticipate that this campaign will be as big as the fight against cigarettes.
    The core science has been with us forever and we have just been provided with the experiments that will break the logjam.  It is a good bet that this test was fended off in many other venues and finally slipped by under a smoke screen.
    Most important we have known for decades that expanding use of sugar was statistically linked to obesity.  The only source of contention was the actual mechanism and there was little contention there.  This work disposes of even that.  Now we know that fructose is the actual driver of obesity.
    I have already argued in earlier post for a general conversion to glucose protocols in the entire food production system.  If sweeteners are the issue we have natural stevia to fix it.  Stevia was finally approved by the FDA just last year after decades of delay.  Stevia provides 5% of sweeteners in Japan which is not a small number.
    I have posted that stevia and glucose should be a safe energy drink that will not produce the damage produced by fructose.  At least it should be much safer and there is reason to think it will be a good answer.
    In the meantime, it is proper to consider a mandatory conversion for all food stuffs.  This needs federal regulation to establish properly.  Let me explain why.  If I am producing any food stuff whatsoever, the best way that I have for making my product taste better than the competition is to add sugar.  That is why it must be regulated out.
    Folks will still get plenty of sugar.  The difference will be that they will do it as their choice.
    Researchers: HFCS is much worse than table sugar 
    22 MAR 2010 12:00 PM
    No refined sugar is good for you–but HFCS seems to be significantly worse. The long-running, contentious debate over the dangers of high fructose corn syrup (HFCS) may be approaching a conclusive end — one not likely to please those sensitive souls over at the Corn Refiners Association.
    While there has been extensive evidence that fructose is harmful to human health and associated with metabolic diseases like diabetes and liver problems, the fact is that plain old table sugar is itself 50 percent fructose. HFCS does have a higher concentration of fructose at 55 percent but it’s close enough to table sugar that most experts continue to dismiss claims that HFCS is on its own more dangerous. And certainly the claim that the introduction of HFCS in the ’80s directly led to the current obesity epidemic continues to be a highly controversial view.
    A massive missing piece in this debate has been an absence of research directly comparing the effects of HFCS and table sugar (as opposed to pure fructose and glucose sugars, which is typically how the research has been conducted). Thanks to a group of researchers at Princeton, however, that missing piece may just have been found (via Science Daily):
    A Princeton University research team has demonstrated that all sweeteners are not equal when it comes to weight gain: Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.
    In addition to causing significant weight gain in lab animals, long-term consumption of high-fructose corn syrup also led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides. The researchers say the work sheds light on the factors contributing to obesity trends in the United States.
    “Some people have claimed that high-fructose corn syrup is no different than other sweeteners when it comes to weight gain and obesity, but our results make it clear that this just isn’t true, at least under the conditions of our tests,” said psychology professor Bart Hoebel, who specializes in the neuroscience of appetite, weight and sugar addiction. “When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they’re becoming obese — every single one, across the board. Even when rats are fed a high-fat diet, you don’t see this; they don’t all gain extra weight.” [Emphasis added.]
    It may not seem like it at first blush, but this is blockbuster stuff. It appears to be a carefully conducted study–note Dr. Hoebel’s point that they fed the rats HFCS at “levels well below those in soda pop”–and one that should give anyone who has been dismissing previous evidence regarding HFCS serious pause (and not the kind that refreshes).
    For all the talk about similarities between HFCS and sugar, there are differences. The researchers note that the fructose in HFCS, though present at only slightly higher levels than in table sugar, is chemically unbound and thus more freely available to the body. Perhaps this aspect of the sweetener is what is causing the now documented metabolic reactions. This revelation is a shoe that I have been predicting might drop, if only someone would get around to it.
    Still, this study doesn’t change the fact that we still eat way too much sugar in all forms. But we now have at least some scientific evidence to suggest that without having pumped ourselves full of HFCS over the last 30 years, the American waistline (and its liver and blood chemistry) would look very very different. It also suggests that the food industry’s insistence in putting HFCS and other corn-based sweeteners in virtually every food product on supermarket shelves was deeply misguided.
    As an added bonus, I’ll direct your attention to this recent Nightline segment on the dangers of fructose. It features UCSF Pediatric Endocrinologist Dr. Robert Lustig, whose [in]famous hour and a half lecture on fructose and its role in obesity has rather surprisingly and thanks to Youtube become a bit of an Internet sensation. And just to be clear, Lustig is no fan of fructose. In fact, he expresses his support to the somewhat skeptical Nightline correspondent for an age limit on soda purchases. Take a look.
  • Micro Desalination Developed




    It is good to see some progress been made on the problem of desalination.  Present tech  works but at great energy cost.  It also works by sharply increasing a portion of the input stream giving the operator a disposal headache in most cases.   Few clever options are conveniently available as we have with the proposal to use water from the Red Sea as input and the Dead Sea for waste output.
    A decade ago I became involved with a physicist who had a cleverer approach but died before it matured.
    This chap has something working at the micron level that does the trick but promises to also be costly.  We shall see.
    The payoff has always been obvious.  Even astoundingly successful Eden Machines (earlier posts) extracting water from the air would benefit from coastal desalination plant supporting coastal growing strips.
    So far this chap’s ambition seems to be a small device convenient to retail users.
    Device to convert seawater offers hope to parched lands
    PARIS (AFP) – Scientists said on Sunday they had made a nanotech device to strip salt from seawater, paving the way to small-scale or even battery-powered desalination for drought-hit regions and disaster zones.
    The tiny prototype is reported on the eve of the UN’s World Water Day, which aims to highlight the worsening problems of access to clean water.
    Conventional desalination works by forcing water through a membrane to remove molecules of salt.
    But this process is an energy-gobbler and the membrane is prone to clogging, which means that de-sal plants are inevitably big, expensive, fixed pieces of kit.
    The new gadget has been given a proof-of-principle test by Jongyoon Han and colleagues of the Department of Electrical Engineering and Computer Science at Massachusetts Institute of Technology (MIT).
    It works through so-called ion concentration polarisation, which occurs when a current of charged ions is passed through an ion-selective membrane.
    The idea is to create a force that moves charged ions and particles in the water away from the membrane.
    When the water passes through the system, salt ions — as well as cells, viruses and micro-organisms — get pushed to the side. This saltier water is then drawn off, leaving only de-salted water to pass through the main microchannel.
    The tiny device had a recovery rate of 50 percent, meaning that half of the water used at the start was desalinated. Ninety-nine percent of the salt in this water was removed.
    Energy efficiency was similar to or better than state-of-the-art large-scale desalination plants.
    “Rather than competing with larger desalination plants, the methods could be used to make small- or medium-scale systems, with the possibility of battery-powered operation,” their paper, published by the journal Nature Nanotechnology, suggests.
    In an email to AFP, Han said the experiment entailed a tiny microfluidic chip, just a few millimetres (fraction of an inch) square, that desalted just 10 microlitres per minute.
    “The idea toward the real-world application is that we would make many of these devices, thousands or tens of thousands of them, on a plate, and operate them in parallel, in the same way semiconductor manufacturers are building many small electronic chips on a single large wafer,” explained Han.
    “That would bring the flow rate up to around 100 millilitres (three fluid ounces) per minute level, which is comparable to typical household water purifiers and therefore useful in many applications.”
    A patent has been filed for the device. However, it may be a matter of years before the invention reaches a commercial scale.
    At such early days, the costs of the future system are unknown.
    But, said Han, overheads may be significantly reduced because gravity can be used to put the water through the device, as opposed to forced it through by pumps, and there is less of a problem of membrane fouling.
    The theme of Monday’s World Water Day is “Clean Water for a Healthy World,” touching on the growing problem of water contamination in countries grappling with water stress and fast-rising populations.

  • Chicken Domestication Revelation




    What is fascinating here is that the two key genes associated with two streams of chicken specialization have been outright isolated and their universality established in present populations.
    It is revealing in that the driving mechanisms of species alteration through domestication is much clearer and progress can be how made with far less controversy.
    Domestication is a powerful process that appears to release a wide range of characteristics never seen in the wild, allowing the derivative breeding we are accustomed to.
     This works assists us in understanding the process much better.
    Scientific Breakthrough In Genetic Studies Of Animal Domestication
    by Staff Writers

    Uppsala, Sweden (SPX) Mar 17, 2010
    A selective sweep takes place when a favorable mutation becomes fixed in a population. This happens in all species during the course of evolution and it happens in domestic animals as a consequence of human-driven selection for favored traits. One of the most interesting findings in this study was a striking selective sweep at the TSHR gene that codes for the thyroid-stimulating hormone receptor.

    The domestication of animals and plants is the most important technological innovation during human history. This genetic transformation of wild species has occurred as humans have used individuals carrying favorable gene variants for breeding purposes. In the current issue of Nature an international team led by researchers at Uppsala University has revealed some of the secrets underlying the remarkable development of the domestic chicken.

    The domestic chicken has in recent years become the most important and cost-effective source of animal protein world-wide. In the beginning of the 20th century specialized layer (egg-producing) and broiler (meat-producing) chickens were developed. The approach has been remarkably successful and has led to huge improvements in productivity.

    “The strategy to study four different populations of layer chickens as well as four broiler populations allowed us to reveal genetic changes of crucial importance for chicken domestication in general as well as changes that were essential for the development of layers or broilers”, says Leif Andersson who coordinated the study.

    In 2004, a draft genome sequence of the chicken was established by sequencing a single female red junglefowl, the wild ancestor of chickens. The task required a major economic investment (millions of US dollars) and a large international team of scientists. In the current study the researchers have used new sequencing technologies and a modest budget to analyze pools of individuals representing eight different populations of the domestic chicken and a red junglefowl population.

    “This is the first study ever where the genetic diversity within and between populations are examined across the whole genome”, says Michael Zody, who did his PhD partially on this project and is now a researcher at the Broad Institute. “The new sequencing technologies allow us to address important biological questions that were impossible to study just a few years ago”.

    A selective sweep takes place when a favorable mutation becomes fixed in a population. This happens in all species during the course of evolution and it happens in domestic animals as a consequence of human-driven selection for favored traits. One of the most interesting findings in this study was a striking selective sweep at the TSHR gene that codes for the thyroid-stimulating hormone receptor.

    In vertebrates, this protein has a key role in metabolic regulation but also in determining the timing of reproduction as a response to changes in day length, a trait that is strictly controlled in most wild animals but which is drastically altered in domestic chickens that can reproduce all year around.

    “Our discovery that every domestic chicken that we have studied representing populations from Sweden to China carry a mutant form of the TSHR protein strongly suggests that this genetic change was an important step in the evolution of the domestic chicken”, says Leif Andersson.

    Another very convincing selective sweep was observed in broiler chickens and involved the TBC1D1 gene, a gene that has previously been associated with obesity in humans and the TBC1D1 protein is involved in the regulation of glucose uptake in muscle cells.

    “Our study shows that billions of broiler chickens worldwide carry a mutant form of the TBC1D1 gene and we are now very eager to identify the causative mutation at this locus and to reveal the molecular mechanism by which it impacts growth”, says Carl-Johan Rubin who was responsible for the bioinformatic analysis of selective sweeps.

    The study is a breakthrough as regards genetic studies of domestic animals.

    “Our study has direct implications for animal breeding and enhances the importance of the domestic chicken as a model organism for biomedical research since we can so effectively reveal genes associated with changes in phenotypic traits”, concludes Leif Andersson.

  • AUTOMATIC ARMATURE BALANCING MACHINE

    Completely automatic operation. Operator simply has to place the jobs at the input station and remove them from the output station. The OK jobs and the OUT OF TOLERANCE jobs are separately stacked.

    4 cutters are provided at the correction station to simultaneously mill on LHS and RHS. This ensures fast correction.

    Correction in 90o components is ideal for jobs having high initial unbalance as compared to polar corrections. Higher depth of milling means more unbalance can be corrected. Secondly, the 90o correction method means that second run balancing is possible.

    Milling system does out to in milling ensuring that the stack is not damaged during milling due to flaring. It also means milling can be done at the ends which reduces the total unbalance correction required.

    An automatic linear transfer system ensures minimum space for operator movement. A rotary transfer system is provided when space limitations are not there.

    Zero clearance ‘slides’ and electronic depth measuring with resolution of 0.05mm helps achieve good correction ratio.

    Brief Description Of Machine.

    Measuring Station.

    This is the heart of the machine where unbalance of the armature is measured. This consists of a main body which houses the pedestal assembly, an electric motor fitted with brake gives drive to the motor. The body also houses force transducers and photo electric module for measurement of unbalance. The machine has an automatic measuring circle. The job has only to be placed on the machine and the start button has to be pressed. Machine starts, measures reading and steps automatically. The readings transfer to the correction station when this job is undergoing correction.

    Correction Station.

    Armatures are corrected for their unbalance on this station automatically. This station is housed with four milling cutters and quick clamping arrangement. The readings from measuring station get transferred to this station and the correction is done automatically by the milling cutters.

This is a big problem, because bogus takedowns are regularly sent for a variety of reasons, including attempts to silence speech and because a copyright holder is taking a machine gun approach to dealing with infringing content. The case that’s received the most attention on this has been the Lenz vs. Universal Music case, involving Universal Music’s failure to take fair use into account in taking down a short video of a baby dancing to music.

    However, Michael Scott points us to Marty Schwimmer’s blog post detailing a content creator’s attempt to claim a bogus DMCA takedown was both copyright infringement itself as well as libel, two rather interesting legal claims… both of which got dismissed pretty quickly. The case involved Actors’ Equity Association (AEA) which apparently has some sort of setup where it has the right to alert YouTube to any videos that violate the copyright of its members. How it knows whether those videos are authorized or not is not at all clear — and, in this case, AEA screwed up. It issued a takedown on a video that was posted by the copyright holder who was pretty pissed off. AEA apologized, but the guy sued, and beyond just using the DMCA’s 512(f) clause on dealing with bogus takedowns, tried some other claims as well — including the copyright infringement and libel claims mentioned above.

    The claim of copyright infringement claim is quite creative. It was based on the fact that copyright gives you the exclusive right to distribute and display your works, and the bogus takedown interfered with those exclusive rights. Of course, there’s a pretty big problem with this theory, which the court was quick to point out: just because copyright law gives you that exclusive right, it doesn’t mean that everyone has to automatically let you distribute or display your works, which is effectively what the guy was claiming. If this theory won out, then no one could stop someone else from displaying their works or it would be considered copyright infringement. So it’s good that the court rejected this. Related to this, the court also rejected the 512(f) claim, by noting that only applies to situations where the takedown issuer had actual knowledge of the fact that the takedown was bogus, which greatly limits its applicability.

    The libel claim stems from the idea that he was falsely labeled for infringing copyrights when he had not done so — and the court ties that to the same 512(f) claim, pointing out that this would only apply if there were actual knowledge that the takedown notice was bogus.

    The ruling here certainly makes sense, but still highlights a massive problem with the DMCA — which is that those issuing takedowns have absolutely no incentive to determine if those takedown notices are valid. This would seem to seriously violate what’s supposed to be a fine balance between copyright law and the First Amendment, in that it allows individuals or companies to stifle the speech of others, using the law, even if they’re doing so incorrectly. This seems like a massive problem in how the DMCA is constructed.

  • Public scepticism prompts Science Museum to rename climate exhibition by Ben Webster, Environment Editor, The Times

    The Science Museum is revising the contents of its new climate science gallery to reflect the wave of scepticism that has engulfed the issue in recent months.

    The decision by the 100-year-old London museum reveals how deeply scientific institutions have been shaken by the public’s reaction to revelations of malpractice by climate scientists.

    The museum is abandoning its previous practice of trying to persuade visitors of the dangers of global warming. It is instead adopting a neutral position, acknowledging that there are legitimate doubts about the impact of man-made emissions on the climate.

    Even the title of the £4 million gallery has been changed to reflect the museum’s more circumspect approach. The museum had intended to call it the Climate Change Gallery, but has decided to change this to Climate Science Gallery to avoid being accused of presuming that emissions would change the temperature.

    Click source to read more, and well done to the Science Museum for putting the “Science” back into the Museum , may it continue to spread into the main stream media.
