From msmash at Slashdot: Wikipedia, the vast online crowdsourced encyclopedia, has a high court. It is a panel called the Arbitration Committee, largely unknown to anyone other than Wiki aficionados, which hears disputes that arise after all other means of conflict resolution have failed. The 15 elected jurists on the English-language Wikipedia’s Arbitration Committee — among them a former staffer for presidential candidate John Kerry, an information-technology consultant in a tiny British village and a retired college librarian — have clerks, write binding decisions and hear appeals. They even issue preliminary injunctions. Referencing the Wall Street Journal: Wikipedia editors got locked in a dispute several months ago about the biographical summary boxes that sit atop some pages of the online Read More ›

Readers may remember Henry Kissinger, a 70s-era American diplomat (“U.S. secretary of state under Richard Nixon, winning the 1973 Nobel Peace Prize for the Vietnam War accords”). From Kissinger at The Atlantic: How the Enlightenment Ends: Philosophically, intellectually—in every way—human society is unprepared for the rise of artificial intelligence. As the internet and increased computing power have facilitated the accumulation and analysis of vast data, unprecedented vistas for human understanding have emerged. Perhaps most significant is the project of producing artificial intelligence—a technology capable of inventing and solving complex, seemingly abstract problems by processes that seem to replicate those of the human mind. This goes far beyond automation as we have known it. Automation deals with means; it achieves prescribed Read More ›

From Emily Conover at Science News: Quantum entanglement has left the realm of the utterly minuscule, and crossed over to the just plain small. Two teams of researchers report that they have generated ethereal quantum linkages, or entanglement, between pairs of jiggling objects visible with a magnifying glass or even the naked eye — if you have keen vision. Physicist Mika Sillanpää and colleagues entangled the motion of two vibrating aluminum sheets, each 15 micrometers in diameter — a few times the thickness of spider silk. And physicist Sungkun Hong and colleagues performed a similar feat with 15-micrometer-long beams made of silicon, which expand and contract in width in a section of the beam. Both teams report their results in Read More ›

From Cornelius Hunter at ENST: Who is the author of the following statement? In contrast [to trait loss], the gain of genetically complex traits appears harder, in that it requires the deployment of multiple gene products in a coordinated spatial and temporal manner. Obviously, this is unlikely to happen in a single step, because it requires potentially numerous changes at multiple loci. If you guessed this was written by an advocate of intelligent design, such as Michael Behe describing irreducibly complex structures, you were wrong. It was evolutionist Sean Carroll and co-workers in a 2007 PNAS paper. When a design person says it, it is heresy. When an evolutionist says it, it is the stuff of good solid scientific research.

From ScienceDaily: In the past decade, scientists have watched protein and RNA molecules condensing into droplets, or membrane-free condensates, in many kinds of cells, from bacterial to human. They have also noted that the same proteins that form liquid droplets in healthy cells can “solidfy” in the context of disease, such as neurodegenerative disorders. But what makes certain molecules come together in the same droplet, while others are excluded, has been unexplained. This week in Science, a team shows for the first time that RNA molecules recognize one another to condense into the same droplet due to specific 3D shapes that the molecules assume. The study’s senior author, Amy S. Gladfelter of University of North Carolina, Chapel Hill, began this Read More ›

From Andrew Jones at ENST: One of the most fundamental and useful ideas that has come out of the intelligent design movement is the insight expressed by Bill Dembski as the Law of Conservation of Information. Put simply, the idea is that information does not appear out of nowhere, but can always be traced to a prior source, analogous to conservation of energy or momentum in physics. It has been used to argue that evolution cannot create information, and I think that is true, so long as you properly understand what we are saying. But a lot of critics have not understood it yet. It has been critiqued from a number of directions; a suspiciously large number of directions in Read More ›

From ScienceDaily: In recent years, researchers have searched for ways to make computers more neuromorphic, or brain-like, in order to perform increasingly complicated tasks with high efficiency. Now Hersam, a Walter P. Murphy Professor of Materials Science and Engineering in Northwestern’s McCormick School of Engineering, and his team are bringing the world closer to realizing this goal. The research team has developed a novel device called a “memtransistor,” which operates much like a neuron by performing both memory and information processing. With combined characteristics of a memristor and transistor, the memtransistor also encompasses multiple terminals that operate more similarly to a neural network. … Typical transistors and Hersam’s previously developed memristor each have three terminals. In their new paper, however, Read More ›

From Oxford University Press, Everything Flows: Towards a Processual Philosophy of Biology, edited by Daniel J. Nicholson and John Dupre, – A radical new conception of biology and the metaphysics of the living world – Offers a new kind of process philosophy with a naturalistic grounding – The Introduction provides a state-of-the-art survey to orient readers new to the topic Here’s the abstract from a chapter by Daniel J. Nicholson, “Reconceptualizing the Organism: From Complex Machine to Flowing Stream,” This chapter draws on insights from non-equilibrium thermodynamics to demonstrate the ontological inadequacy of the machine conception of the organism. The thermodynamic character of living systems underlies the importance of metabolism and calls for the adoption of a processual view, exemplified Read More ›

From Elise Crull at Aeon: The problem is that entanglement violates how the world ought to work. Information can’t travel faster than the speed of light, for one. But in a 1935 paper, Einstein and his co-authors showed how entanglement leads to what’s now called quantum nonlocality, the eerie link that appears to exist between entangled particles. If two quantum systems meet and then separate, even across a distance of thousands of lightyears, it becomes impossible to measure the features of one system (such as its position, momentum and polarity) without instantly steering the other into a corresponding state. Up to today, most experiments have tested entanglement over spatial gaps. The assumption is that the ‘nonlocal’ part of quantum nonlocality Read More ›

as in “your last question, the question for which you will be remembered.” Some interesting answers (in the form of questions) emerge: Can we program a computer to find a 10,000-bit string that encodes more actionable wisdom than any human has ever expressed? – Scott Aronson Are complex biological neural systems fundamentally unpredictable? – Anthony Aguirre Are the simplest bits of information in the brain stored at the level of the neuron? – Dorsa Amir and many more. Everyone seems to be trying their hand on the 20th anniversary. See also: CSICOP’s ridiculously out-of-date questions and answers on evolution show how far naturalism has fallen They don’t even keep up.

From Brian Miller at Evolution News & Views: The first issue relates to the comparison of the sequencing of amino acids in proteins to the letters in a sentence. This analogy is generally disliked by design critics since it so clearly reveals the powerful evidence for intelligence from the information contained in life. It also helps lay audiences see past the technobabble and misdirection often used to mislead the public, albeit unintentionally. … The challenge for nucleotide based enzymes (ribozymes) is equally daunting. Stumbling across a random sequence that could perform even one of the most basic reactions also requires a search library in the trillions. So, any multistage process would also be beyond the reach of chance. A glimmer Read More ›

From O’Leary for News at Evolution News & Views: Philosopher of consciousness John Searle identified this underlying theme of post-modernism in Mind, Language and Society: Philosophy in the Real World (2008): “[I]t satisfies a basic urge to power. It just seems too disgusting, somehow, that we should have to be at the mercy of the ‘real world.’” If consciousness is an illusion, the comfort is that there is no “real world” anyway, just the one we insist on. Science may not survive this. For one thing, science opinion leaders are themselves putting failing claims beyond the reach of disconfirmation by evidence. If design proponents did nothing but confront that fact, in the face of tenured nihilists and Wikipedian trolls, it Read More ›

From philosopher Laura Ruggles at Aeon: What does it even mean to say that a mallow can learn and remember the location of the sunrise? The idea that plants can behave intelligently, let alone learn or form memories, was a fringe notion until quite recently. Memories are thought to be so fundamentally cognitive that some theorists argue that they’re a necessary and sufficient marker of whether an organism can do the most basic kinds of thinking. Surely memory requires a brain, and plants lack even the rudimentary nervous systems of bugs and worms. However, over the past decade or so this view has been forcefully challenged. The mallow isn’t an anomaly. Plants are not simply organic, passive automata. We now Read More ›

Dr E. Selensky occasionally requests that UD posts an article on his behalf. What follows is his latest: ______________ Arguably, the RNA world model is excessively complex: it operates too complex structures and involves too complex interactions. The origin of life, some researchers believe, must have been simpler.In an attempt to close the gap between chemistry and life by naturalistic means a new model has been proposed recently, yet another one of many, that seeks to explain the rise of RNAs. This model is called template-assisted ligation. It has been proposed by Alexey Tkachenko and Sergei Maslov at American Institute of Physics. They hope it can help shed light on what could have preceded the RNA world.The crux of the Read More ›

Information, of course, is notoriously a concept that has many senses of meaning. As it is central to the design inference, let us look (again) at defining it. We can dispose of one sense right off, Shannon was not directly interested in information but in information-carrying capacity; that is why his metric will peak for a truly random signal, which has as a result minimal redundancy. And, we can also see that the bit measure commonly seen in ICT circles or in our PC memories etc, is actually this measure, 1 k bit is 1,024 = 2^10 binary digits of storage or transmission capacity. One binary digit or bit being a unit of information storing one choice between a pair Read More ›
