Comet contains glycine, but so what?

From Phys.org: An important amino acid called glycine has been detected in a comet for the first time, supporting the theory that these cosmic bodies delivered the ingredients for life on Earth, researchers said Friday. Glycine, an organic compound contained in proteins, was found in the cloud around Comet 67P/Churyumov-Gerasimenko by the European Space Agency’s probe, Rosetta, said the study in the journal Science Advances. That said, Previous data from Rosetta has shown that water on Comet 67P/C-G is significantly different from water on Earth, suggesting that comets did not play as big a role in delivering water as once thought.More. Our favourite physicist Rob Sheldon thinks comets played a role, and that sounds reasonable. The big problem is that Read More ›

Nature on the reproducibility “crisis”

It’s real. From Nature: Survey sheds light on the ‘crisis’ rocking research. More than 70% of researchers have tried and failed to reproduce another scientist’s experiments, and more than half have failed to reproduce their own experiments. Those are some of the telling figures that emerged from Nature’s survey of 1,576 researchers who took a brief online questionnaire on reproducibility in research. The data reveal sometimes-contradictory attitudes towards reproducibility. Although 52% of those surveyed agree that there is a significant ‘crisis’ of reproducibility, less than 31% think that failure to reproduce published results means that the result is probably wrong, and most say that they still trust the published literature.More. Excuse me. In community medicine, this is called “denial.” 1. Read More ›

Junk DNA a successor to Piltdown Man?

Not that you’d ever guess from the story at Scienmag, but It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns, non-coding sequences of DNA located within genes, multiply in a genome. The results, published today in the Proceedings of the National Academy of Sciences, address fundamental questions about the evolution of new species and could expand our understanding of gene expression and the causes of diseases such as cancer. … For a long time, scientists have known that much of the DNA within any given organism’s genome does not code for functional molecules or protein. However, recent research has found that Read More ›

Cornelius Hunter’s response to Dennis Venema

Here: It does not seem that the evidence supports evolutionary theory as Venema concludes. In fact, there seem to be several significant problems with this claim, as I will explain. First, as we saw in my previous article, the genetic data from the different species do not fall into the expected evolutionary pattern. Here Venema focuses on the high genetic similarity between the primates, claiming it confirms evolution. But if this is what is required to confirm evolutionary relationships, then the substantial genetic differences that are so often found between otherwise similar species must falsify evolutionary relationships in those cases. But evolutionists have never entertained any such doubts. Those evolutionary relationships are intact, according to evolutionists, and this suggests that Read More ›

Fake peer reviews: Missing fairly obvious clues

From Retraction Watch: The editors of a journal that recently retracted a paper after the peer-review process was “compromised” have published the fake reviews, along with additional details about the case. In the editorial titled “Organised crime against the academic peer review system,” Adam Cohen and other editors at the British Journal of Clinical Pharmacology say they missed “several fairly obvious clues that should have set alarm bells ringing.” For instance, the glowing reviews from supposed high-profile researchers at Ivy League institutions were returned within a few days, were riddled with grammar problems, and the authors had no previous publications. The case is one of many we’ve recently seen in which papers are pulled due to actions of a third Read More ›

Animal minds: Do animals grieve?

Anyone who has ever lived with animals knows that they do. So what’s with all the pop science fluff about how monkeys grieve, as if it is supposed to prove something? A friend offers some vids: Penguin mourns the death of her chick Mourning doves care for deceased mates Chickens also. Birds make monkey mourning look average. One wishes the zeal did something for animals, instead of crackpots. But nope. There’s no money in that. See also: Claim: Monkeys understand irreversibility of death No. and Are apes entering the Stone Age?

Cranky young sun kickstarted life? No.

Unless you believe New Scientist: Giant flare-ups from the young sun might have kept early Earth warm – and any life nicely fertilised. By splitting inert nitrogen molecules in the atmosphere, charged particles from the sun could have sparked chemical reactions that heated the planet and could be the precursor for life. This suggestion is the latest attempt to solve a famous paradox known as the “faint young sun” problem. About 4 billion years ago, the sun was only 70 per cent as bright as it is today, which should have made the Earth a frozen snowball. But geological evidence shows that ancient Earth was warm enough for liquid water. The same holds true for Mars. Now, Vladimir Airapetian of NASA’s Read More ›

Being Green Means Never Saying You’re Sorry for Killing Millions

Robert Tracinski tells us why the greenies will never admit that they were dead wrong (pun intended) about DDT, even though their mistakes have led to the death of millions: So why not just admit that the hysteria whipped up over DDT was wrong? Because this was the founding issue of the environmentalist movement. Rachel Carson’s “Silent Spring” was the first book to convince the common man that “chemicals” are scary and that modern industry and technology were going to destroy us. Banning DDT was the first triumph of the environmentalist movement in using political pressure to override scientific skepticism and impose its agenda by force. http://thefederalist.com/2016/05/27/yes-you-can-blame-the-ddt-ban-for-zika/  

Paul Davies: Maybe life is rare after all

From physicist Paul Davies (who was on a committee(2009) to discuss what to do if aliens landed) Scientific American: Another common argument is that the universe is so vast there just has to be life out there somewhere. But what does that statement mean? If we restrict attention to the observable universe there are probably 1023 planets. Yes, that’s a big number. But it is dwarfed by the odds against forming even simple organic molecules by random chance alone. If the pathway from chemistry to biology is long and complicated, it may well be that less than one in a trillion trillion planets ever spawns life. Affirmations that life is widespread are founded on a tacit assumption that biology is not Read More ›

Time capsules now officially non-PC

Even icon Carl Sagan doesn’t get a pass these days. From Cara Giaimo at Atlas Obscura: Throughout human history, people have struggled with two competing impulses: the desire to make a mark for future generations, and a deep confusion about what, exactly, that mark should be. The Golden Records, though probably the most extreme manifestation of this impulse, are far from the first. “There have been time-capsule type experiences ever since humans have measured time,” writes librarian William Jarvis in Time Capsules: A Cultural History. It’s easy to make fun of time capsules, but, as Jarvis details, it’s much harder to fill them with the kind of material that will actually stand the test of time. Often, the things we Read More ›

Why Deny Objective Morality?

In another thread, after a lengthy debate about whether or not we treat morality like it is a subejctive preference or an objective commodity, Zeroseven graciously admits: Fair enough. I don’t disagree with most of what you say. I agree we behave as if morals are objective. But I don’t agree that this is because they are objective. … I see the argument of objective morals in the same way. Its a nice way to look at a human process for making decisions about the world. But of course its a pure fiction. First, I’d like to thank Zeroseven for having the courage to admit what few moral subjetivists will; all sane people act as if morality refers to an Read More ›

Neanderthals built “mysterious” stone circles

From National Geographic: The strange rings are crafted from stalagmites and are roughly 176,000 years old, scientists report today in Nature. And if the rings were built by a bipedal species, as archaeologists suspect, then they could only be the work of Neanderthals, ancient human relatives that are proving to be much more “human” than anticipated. “This discovery provides clear evidence that Neanderthals had fully human capabilities in the planning and the construction of ‘stone’ structures, and that some of them penetrated deep into caves, where artificial lighting would have been essential,” says paleoanthropologist Chris Stringer of the Natural History Museum in London.More. And, from Nature, no one knows why they did it: “The big question is why they made Read More ›

Jon Garvey on Michael Denton’s Evolution Still a Theory in Crisis

At Hump of the Camel: Not that Denton’s thesis is entirely new. Perhaps the simplest summary is that it is a re-affirmation of his first book questioning the Neodarwinian Synthesis thirty years ago, now strengthened by much work in biology since, combined with a new structuralist viewpoint which he inherits from Richard Owen before and during Darwin’s time. I might add (because Denton doesn’t stress it) that structuralism – the idea that much of biological form depends on lawlike constraints, rather than adaptive contingency – was the prevalent theory of evolution, in the form of orthogenesis, at the time when Darwinism was found wanting in explanatory power at the beginning of the twentieth century. It was only the Neodarwinian Synthesis Read More ›

Dawkins: Social justice warriors are dim, just dim …

Every so often, Richard Dawkins hits the target. Here’s his take on the junior jackboots of Asshat U Washington Times: “There seems to be a tendency among some students – perhaps the less intelligent – to suppress free speech,” Mr. Dawkins said in an interview with the Australian on Monday. “I hope it doesn’t last long.” More. There are two reasonable opinions about whether the SJWs are dim. Some would say they know how to get on very well after the collapse of the traditional humanities, and aim at careers in enforcement of Correctness of some kind. Of course, one hardly need be a genius for that. In fact, a lack of genuine curiosity is a great asset. But what’s this Read More ›

Less science, more crackdowns!

The global warming hype, unlike the nutrition freakout or the far side of Darwinism, could actually be true. But the behaviour of the proponents tells against that. From Willie Soon and István Markó at : Increasingly, we are seeing more and more outrageous and aggressive anti-scientific claims that anyone who is not willing to embrace the dangerous global warming bandwagon and to condemn its culprit, CO2, is actually the equivalent of a Holocaust Denier. This sort of name-calling, loud self-promotion and fact twisting actions, closer to political rodeo than to healthy scientific debates, are simply telling us that our opponents have already lost their fallacious arguments and are getting short on any real scientific facts. Professor Albert Einstein had it Read More ›
