From ScienceDaily: Paleontologists at the University of Toronto (U of T) and the Royal Ontario Museum (ROM) in Toronto have entirely revisited a tiny yet exceptionally fierce ancient sea creature called Habelia optata that has confounded scientists since it was first discovered more than a century ago. In those days, we had it all sewn up except for a few outliers. Then… The researchers argue that this difference in anatomy allowed Habelia to evolve an especially complex head that makes this fossil species even more peculiar compared to known chelicerates. The head of Habelia contained a series of five appendages made of a large plate with teeth for mastication, a leg-like branch with stiff bristle-like spines for grasping, and an Read More ›

Not always how we think. Forewarned is forearmed. From Emerging Technology at MIT Review: How easy is it for malicious actors to distort the public perception of science? Today we get an answer thanks to the work of James Owen Weatherall, Cailin O’Connor at the University of California, Irvine, and Justin Bruner at the Australian National University in Canberra, who have created a computer model of the way scientific consensus forms and how this influences the opinion of policy makers. The team studied how easily these views can be distorted and determined that today it is straightforward to distort the perception of science with techniques that are even more subtle than those used by the tobacco industry. … Indeed, the Read More ›

From Rebecca Boyle at Quanta: From a seam in one of these hills, a jumble of ancient, orange-Creamsicle rock spills forth: a deposit called the Apex Chert. Within this rock, viewable only through a microscope, there are tiny tubes. Some look like petroglyphs depicting a tornado; others resemble flattened worms. They are among the most controversial rock samples ever collected on this planet, and they might represent some of the oldest forms of life ever found. Last month, researchers lobbed another salvo in the decades-long debate about the nature of these forms. They are indeed fossil life, and they date to 3.465 billion years ago, according to John Valley, a geochemist at the University of Wisconsin. If Valley and his Read More ›

From Christian Scientific Society: The meeting will take place January 26-27 at Biola University. On Friday night, we will have a debate between David Snoke (me) and Mike Keas on “Are predatory animals a result of the Fall?” (Mike: yes; David: no). This question lies at the core of much of the debate about science and Christianity: could God have had a hand in what we consider to be natural evils? Are they the result of people’s sin, or random forces, not God? Saturday afternoon, we will have four speakers addressing issues on the general topic of natural evil More. Christian Scientific Society also notes, Save the date for the April meeting in Pittsburgh Dates are April 6-7, at the Read More ›

I recently cited a paper on the evolution of embryonic development and how the evidence contradicts evolutionary theory and common descent. Even the evolutionists, though in understated terms, admitted there were problems. Evolutionary analyses are “reaching their limits,” it is difficult to “conclude anything about evolutionary origins,” genetic similarities “do not necessarily imply common ancestry,” and “conserved regulatory networks can become unrecognizably divergent.” In other words, like all other disciplines within the life sciences, embryonic development is not working. The science contradicts the theory.  Read more

From Sabine Hossenfelder, author of the forthcoming Lost in Math: How Beauty Leads Physics Astray (June, 2018), at NPR: For centuries, progress in the foundations of physics has been characterized by simplification. Complex processes — such as the multitude of chemical reactions — turned out to arise from stunningly simple underlying equations. And simplicity carried us a long way. According to physicists’ best theories today, everything in our universe emerges from merely 25 elementary particles and four types of forces. So, yes, simplicity — often in the form of unification — has been extremely successful. For this reason, many physicists want to further simplify the existing theories. But you can always simplify a theory by removing an assumption. Like the assumption that Read More ›

From ScienceDaily: Researchers at the Royal Ontario Museum and the University of Toronto have described an exceptionally well-preserved new fossil species of bristle worm called Kootenayscolex barbarensis. Discovered from the 508-million-year-old Marble Canyon fossil site in the Burgess Shale in Kootenay National Park, British Columbia, the new species helps rewrite our understanding of the origin of the head in annelids, a highly diverse group of animals which includes today’s leeches and earthworms. This research was published today in the journal Current Biology in the article “A New Burgess Shale Polychaete and the Origin of the Annelid Head Revisited.” … One key feature of the new Burgess Shale worm Kootenayscolex barbarensis is the presence of hair-sized bristles called chaetae on the Read More ›

From Dan Garisto at ScienceNews: Storms of powdery Martian soil are contributing to the loss of the planet’s remaining water. This newly proposed mechanism for water loss, reported January 22 in Nature Astronomy, might also hint at how Mars originally became dehydrated. Researchers used over a decade of imaging data taken by NASA’s Mars Reconnaissance Orbiter to investigate the composition of the Red Planet’s frequent dust storms, some of which are vast enough to circle the planet for months. During one massive dust storm in 2006 and 2007, signs of water vapor were found at unusually high altitudes in the atmosphere, nearly 80 kilometers up. That water vapor rose within “rocket dust storms” — storms with rapid vertical movement — Read More ›

From ScienceDaily: The team studied the transparent roundworm (C. elegans), which shares about 60-80% of the same genes as humans, to shed light on the importance of mechanisms regulating the frequency of gene mutations in different cells and organs. “C. elegans and humans share very similar mitochondria, and it is a useful organism as we can genetically tease apart the mechanisms of what is happening at a cellular level,” he said. The researchers developed an exceptionally pure method of isolating mitochondria from specific cells in the body to study them in detail. “We now suspect that there is a mechanism in all animals that can filter out these mutations before they are passed to future offspring, which could otherwise cause Read More ›

From molecular biologist Jonathan Wells at Salvo: In 2005, Douglas Futuyma published a textbook about evolution claiming that “no intelligent engineer would be expected to design” the “functionally nonsensical arrangement” of cells in the human retina. That same year, geneticist Jerry Coyne wrote that the human eye is “certainly not the sort of eye an engineer would create from scratch.” Instead, “the whole system is like a car in which all the wires to the dashboard hang inside the driver’s compartment instead of being tucked safely out of sight.” Like Dawkins, Williams, Miller, and Futuyma, Coyne attributed this arrangement to unguided evolution, which “yields fitter types that often have flaws. These flaws violate reasonable principles of intelligent design.” We can be Read More ›

Extinct species’ DNA suggests so, according to researchers. From Ewen Callaway at Nature: Scientists had assumed from fossil evidence that an ancient predecessor called the straight-tusked elephant (Paleoloxodon antiquus), which lived in European forests until around 100,000 years ago, was a close relative of Asian elephants. In fact, this ancient species is most closely related to African forest elephants, a genetic analysis now reveals. Even more surprising, living forest elephants in the Congo Basin are closer kin to the extinct species than they are to today’s African savannah-dwellers. And, together with newly announced genomes from ancient mammoths, the analysis also reveals that many different elephant and mammoth species interbred in the past. More. Speciation ain’t what it used to be. Read More ›

Retired linguist Noel Rude writes to offer further thoughts on language and agency*: –0– English is, of course, quite capable of describing random and deterministic states and events. It is because the origin of life and its history are neither random nor deterministic that the materialists have such trouble. As for ambitransitive verbs, languages do differ. At one extreme is a Liberian language, Loma, that I once worked with. All its verbs are ambitransitive. In English, not all verbs are. Consider ‘eat’, for example. The Loma, however, can say (I don’t remember the words), He ate the food The food ate Where 2) is best translated by our passive: ‘the food was eaten’. At the other extreme are languages like Read More ›

From Sarah Gibbens at National Geographic: The appearance of the 18-year-old woman, whom researchers named named Avgi, or ‘Dawn,’ is based on a female skull excavated from a cave occupied in 7,000 B.C. … Facial features have “smoothed out” over millennia, and humans look less masculine today, says reconstructor Oscar Nilsson. More. Now if we could just get a group reconstruction we would know whether she looked typical for her era. Or whether the facial expression is usual.

From ScienceDaily: In this study the authors were able to identify how a protein called p62 is activated to induce autophagy. They found that p62 can be activated by reactive oxygen species (ROS). ROS are by-products of our metabolism that can cause damage in the cell. This ability of p62 to sense ROS allows the cell to remove the damage and to survive this stress. In lower organisms, such as fruit flies, p62 is not able to do this. The team identified the part of the human p62 protein which allows it to sense ROS and created genetically modified fruit flies with ‘humanised’ p62. These ‘humanised’ flies survived longer in conditions of stress. Dr Korolchuk adds: “This tells us that Read More ›

At Evolution News & Science Today, various reflections are offered on Dennis Venema and Scot McKnight’s Adam and the Genome: Genomic science indicates that humans descend not from an individual pair but from a large population. What does this mean for the basic claim of many Christians: that humans descend from Adam and Eve? Leading evangelical geneticist Dennis Venema and popular New Testament scholar Scot McKnight combine their expertise to offer informed guidance and answers to questions pertaining to evolution, genomic science, and the historical Adam. (jacket copy) From ENST: Much of Dennis Venema’s Adam and the Genome Isn’t About Adam and the Genome: While Discovery Institute takes no view on Adam and Eve, the book does offer an opportunity Read More ›
