Climate scientist Judith Curry is a TENURED professor.  But she has had enough.  She announced her resignation last week, citing the literal craziness of the climate science authoritarianism.  She writes: A deciding factor was that I no longer know what to say to students and postdocs regarding how to navigate the CRAZINESS in the field of climate science. Research and other professional activities are professionally rewarded only if they are channeled in certain directions approved by a politicized academic establishment — funding, ease of getting your papers published, getting hired in prestigious positions, appointments to prestigious committees and boards, professional recognition, etc. How young scientists are to navigate all this is beyond me, and it often becomes a battle of scientific integrity versus Read More ›

From the editors of Nature: The article by Mark Lilla, a researcher at Columbia University in New York City who specializes in the history of Western intellectual, political and religious thought, called for an end to what he described as an overemphasis by liberals on racial, gender and sexual identity politics. He believes that this focus distracts from core fundamental concepts of democracy and so weakens social cohesion and civic responsibility. In short, he asserted that many progressives live in bubbles; that they are educationally programmed to be attuned to diversity issues, yet have “shockingly little to say” about political and democratic fundamentals such as class, economics, war and policy issues affecting the common good. Of direct relevance to the Read More ›

Pot. Kettle. Rusty. From Michael Shermer at Scientific American: Have you ever noticed that when you present people with facts that are contrary to their deepest held beliefs they always change their minds? Me neither. In fact, people seem to double down on their beliefs in the teeth of overwhelming evidence against them. The reason is related to the worldview perceived to be under threat by the conflicting data. Creationists, for example, dispute the evidence for evolution in fossils and DNA because they are concerned about secular forces encroaching on religious faith. Anti-vaxxers distrust big pharma and think that money corrupts medicine, which leads them to believe that vaccines cause autism despite the inconvenient truth that the one and only Read More ›

From Wayne State biologist Wayne Rossiter at his blog: A critique of Plantinga’s argument for the compatibility of Darwinian evolution and Christianity. Plantinga’s principle concern (stated in the first line of his first essay) is “Are science and religion compatible?” After some meandering, he refines the search a bit, offering, “Theistic religion endorses special divine action in the world—miracles, for example—but such action would contravene the laws promulgated by science. There is such a thing as the scientific worldview, and it is incompatible with theistic religion.” If it were true that “science” as a practice rightly conforms to this “scientific worldview” (read: naturalism), then I suppose we could stop here (on page two of the essay) and say that Plantinga Read More ›

From astronomer Chris Impey at Nautilus: Interdependence and impermanence. The words have different meanings to a scientist and a Buddhist, but they provide a common ground for a discussion of the interactions and transformations that pervade the physical universe. To a Buddhist, impermanence means there is no permanent and fixed reality; everything is subject to alteration and change. The Buddha said that life is a series of different moments, joining to give the impression of continuous flow, like a river. The scientific view is similar, from a human as a persistent biological pattern even as the cells are continuously living and dying, to the processes in the universe that continuously exchange and transform matter and energy. Buddhist interdependence means that Read More ›

And birds still fly forwards too, no less. From Jesse Singal at New York Magazine: a paper published last month in Current Psychology by Christopher Ferguson of Stetson University and Jeffrey Brown and Amanda Torres of Texas A&M, the authors evaluated a bunch of psychology textbooks to see how rigorously they covered a bunch of controversial or frequently misrepresented subjects. The results weren’t great. In spring of 2012, Ferguson and his colleagues solicited and received 24 popular introductory textbooks, and then got to work evaluating them. Specifically, they evaluated those textbooks’ coverage of seven “controversial ideas in psychology” — ideas where there’s genuine mainstream disagreement among researchers — and also checked for the presence of five well-known scientific urban legends Read More ›

From Marcelo Gleiser at Nautilus: The modern version of the unifying quest is string theory, which supposes that the fundamental entities in nature are vibrating tubes of energy instead of point-like particles of matter. Different vibrating modes correspond to the different particles we observe, just as different vibrating frequencies of a violin string correspond to different sounds. When I joined theoretical physics in the mid-1980s, the grand task was to find the unique solution to string theory: our universe with all its particles and forces. We believed success was just around the corner, that nature was indeed a mathematical code in a 10-dimensional spacetime, nine for space, one for time. … Alas, it wasn’t meant to be. Fast-forward three decades, Read More ›

From Salk Institute: “Our research shows that, despite having exactly the same genes and neurons as adults, adolescent roundworms have completely different food-seeking preferences and abilities,” says Sreekanth Chalasani, associate professor in Salk’s Molecular Neurobiology Laboratory and senior author of the paper published in eNeuro in January 2017. “It is in adulthood that we finally see the worms become more efficient and competent at finding food.” The microscopic Caenorhabditis elegans worm may seem like an odd source of insight into human brain development. With only 302 neurons to humans’ almost 100 billion, C. elegans is a vastly simpler organism but its basic neurological circuitry has many similarities to ours. And, since scientists have already mapped the adult roundworms’ neurons anatomically Read More ›

For years we have been deluged with science news stories about how this or that datum might finally be the breakthrough demonstrating that earth is not unique in the universe for harboring life.  Why are some scientists so obsessed with ET?  I was thinking about this the other day and it occurred to me that this phenomenon is essentially religious in nature. Suppose you are a scientist with a strong faith commitment in atheistic materialism.  Maintaining any faith commitment can sometimes be hard even for true believers.  This is especially the case for materialists, who must grit their teeth and hang on to their faith in the face of overwhelming evidence that materialism is false.  Consider their origin of life Read More ›

From ScienceDaily: Delicate fossil remains of tomatillos found in Patagonia, Argentina, show that this branch of the economically important family that also includes potatoes, peppers, tobacco, petunias and tomatoes existed 52 million years ago, long before the dates previously ascribed to these species, according to an international team of scientists. … “Paleobotanical discoveries in Patagonia are probably destined to revolutionize some traditional views on the origin and evolution of the plant kingdom,” said N. Rubén Cúneo, CONICET, Museo Palentológico Egidio Feruglio. Paper. (paywall) – Peter Wilf, Mónica R. Carvalho, María A. Gandolfo, N. Rubén Cúneo.

From U Minnesota: About 4.6 billion years ago, a cloud of gas and dust that eventually formed our solar system was disturbed. The ensuing gravitational collapse formed the proto-Sun with a surrounding disc where the planets were born. A supernova—a star exploding at the end of its life-cycle—would have enough energy to compress such a gas cloud. Yet there was no conclusive evidence to support this theory. In addition, the nature of the triggering supernova remained elusive. Qian and his collaborators decided to focus on short-lived nuclei present in the early solar system. Due to their short lifetimes, these nuclei could only have come from the triggering supernova. Their abundances in the early solar system have been inferred from their Read More ›

From PNAS: Recent developments in synthetic biology enable one-step implementation of entire metabolic pathways in industrial microorganisms. A similarly radical remodelling of central metabolism could greatly accelerate fundamental and applied research, but is impeded by the mosaic organization of microbial genomes. To eliminate this limitation, we propose and explore the concept of “pathway swapping,” using yeast glycolysis as the experimental model. Construction of a “single-locus glycolysis” Saccharomyces cerevisiae platform enabled quick and easy replacement of this yeast’s entire complement of 26 glycolytic isoenzymes by any alternative, functional glycolytic pathway configuration. The potential of this approach was demonstrated by the construction and characterization of S. cerevisiae strains whose growth depended on two nonnative glycolytic pathways: a complete glycolysis from the related Read More ›

From Science: Abstract: Differentiated cells in a culture dish can assume a new identity when manipulated to express four transcription factors. This “reprogramming” process has sparked interest because conceivably it could be harnessed as a therapeutic strategy for tissue regeneration. Mosteiro et al. used a mouse model to study the signals that promote cell reprogramming in vivo. They found that the factors that trigger reprogramming in vitro do the same in vivo; however, they also inflict cell damage. The damaged cells enter a state of senescence and begin secreting certain factors that promote reprogramming, including an inflammatory cytokine called interleukin-6. Thus, in the physiological setting, cell senescence may create a tissue context that favors reprogramming of neighboring cells. (paywall) – Read More ›

From Tasneem Zehra Husain at Nautilus: It’s not the immensity or even the inscrutability, but that it reduces physical law to happenstance. Not just a feature, a benefit. I am not alone in my ambivalence. The multiverse has been hotly debated and continues to be a source of polarization among some of the most prominent scientists of the day. The debate over the multiverse is not a conversation about the particulars of a theory. It is a fight about identity and consequence, about what constitutes an explanation, what proof consists of, how we define science, and whether there is a point to it all. … The multiverse is less like a closed door and more like a key. To me, Read More ›
