If humans are just animals, why should a ban on eating meat apply to humans but not cats?

Should the consumption of animal products be banned? Here. In this book, Jan Deckers addresses the most crucial question that people must deliberate in relation to how we should treat other animals: whether we should eat animal products. Many people object to the consumption of animal products from the conviction that it inflicts pain, suffering, and death upon animals. This book argues that a convincing ethical theory cannot be based on these important concerns: rather, it must focus on our interest in human health. Tending to this interest demands not only that we extend speciesism-the attribution of special significance to members of our own species merely because they belong to the same species as ourself-towards nonhuman animals, but also that Read More ›

Journalist on fine-tuning of the universe

From David Warren at the Catholic Thing: Thirty years have now passed since the publication of an extraordinary book, by a respectable publisher (the Oxford University Press). This was, The Anthropic Cosmological Principle, by the witty British astronomer, John Barrow, and the brilliant American mathematical physicist, Frank Tipler. It included a laudatory preface by John Wheeler, co-inventor or discoverer of “black holes.” It was an attempt to overturn the Copernican Revolution: to put man back at the centre of a miraculously conceived universe, and make his fate the whole meaning of it. This universe, from its Alpha Point in what is popularly called the “Big Bang,” to an Omega Point that is darkly foreseeable, could be described in no sense Read More ›

Popper wrong on falsification?

From Alex Berezow at American Council on Science and Health: In other words, only one out of 70 papers fully met Popper’s criteria of falsification. This suggests that while Popper’s idea of falsification is a good one, it is far too difficult for scientists to implement regularly in practice. Science plods along just fine without adhering to Popper’s overly burdensome guidelines. Though he would surely dispute Dr. Hansson’s conclusion that falsification has been falsified, hopefully Popper would have at least found it amusingly ironic.More. Berezow is (perhaps ironically) missing the point here, of course. Falsification is a standard, adherence to which need not be perfect. But it provides a basis for discussion of claims. Among the people to whom that Read More ›

Fire nature and hire a different one

Fracking edition. From Hot Air: The draft report on hydraulic fracturing (“fracking”) from the EPA is nearing the end of its more than five year journey and the findings were a major blow to the green energy crowd. Try as they might, there simply was no evidence of systemic contamination to ground water or other resources and the report essentially gives the practice a qualified thumbs up. More.

Why Einstein was considered daring

From JStor Daily: As late as 1923, a British physicist despaired his coevals were still “ignorant of Einstein’s work and not very much interested in it.” British physicists Ebenezer Cunningham and Norman R. Campbell were at first quite lonely introducing Einstein to their countrymen and challenging the “ethereal” view. Campbell seems to have been the only anti-ether voice from 1905 to 1911.More. Of course, in its day, ether was a reasonable belief as—in its day—was the belief that Earth was the point of the universe down to which all things fell (geocentric system). As anthropologist J. G. Frazer put it The views of natural causation embraced by the savage magician no doubt appear to us manifestly false and absurd; yet Read More ›

Physicist: “T violation” could be origin of time

From ScienceDaily: Associate Professor Dr Joan Vaccaro, of Griffith’s Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called ‘T violation’ could be the origin of time evolution and conservation laws. “I begin by breaking the rules of physics, which is rather bold I have to admit, but I wanted to understand time better and conventional physics can’t do that,” Dr Vaccaro says. “I do get conventional physics in the end though. This means that the rules I break are not fundamental. It also means that I can see why the universe has those rules. And I can also see why the universe advances in time.” Paper. (public access) More. – Joan Read More ›

Zircons as earliest evidence of life on Earth?

Zircons. From Ross Pomeroy at RealClearScience: The oldest-known zircons, discovered in the Jack Hills of Western Australia, originally crystalized 4.4 billion years ago! It was within one of these zircons that geochemist Elizabeth Bell and her team discovered the carbon they think was produced by life. Life that old, whatever it was, would not have bones, or even a clearly-defined shape, so a true fossil find will probably never be unearthed. Instead, whatever carbon-based life existed back in the Hadean would simply leave traces of itself in the form of carbon itself. Bell’s co-author, Mark Harrison, referred to the stuff as “the gooey remains of biotic life.” More. See also: Earth’s crust cooled only 160 million years after solar system Read More ›

Plasticity tampers with jaw fossil record?

From ScienceDaily: Scientists use the fossil record to make judgments on the physiology and behavior of species. But are those interpretations correct? New research puts into question how we interpret the behavior of extinct organisms from their fossil remains, and the greater role of plasticity in determining evolution diversity.More. Paper.

Natural selection hard to measure?

You mean the same way that  ghosts in the barn loft are hard to find? From Evolution News & Views: Charles Darwin’s idea that an unguided natural process led to all the beauty and diversity of the world, including its Undeniable appearance of design, guides scientific thinking to this day. But what if his signature mechanism — natural selection — cannot be measured? Without measurement, a theory reduces to anecdote. A recent paper in the Proceedings of the National Academy of Sciences threatens to do that, at least in regard to “the evolution of human body form.” The implications go far beyond human physiology. Consider limb length. Say you want to deduce how natural selection has affected the dimensions of Read More ›

Darwin-in-the-schools vs. Reason to Believe’s Fuz Rana

From Fuz Rana at Poached Egg: Generally speaking, the reaction to my book The Cell’s Design has been positive. But there have been a few reviews that were less than stellar. Perhaps the most critical of all was a review written by microbiologist Frank Steiner for the Reports of the National Center for Science Education. After careful reflection, I have come to conclude that many of the issues Steiner has with The Cell’s Design are unsubstantial and largely unfounded. Nevertheless, one point he raised has some merit. Fortunately, a recent discovery by researchers from Germany about the structure of the enzyme F1-F0-ATPase helps address Steiner’s point—and in doing so, actually strengthens my argument for the intelligent design of biochemical systems.

Universe’s abundance of lithium still a mystery

From Kelsey Houston-Edwards at PBS: The difference between Lithium-6 and Lithium-7 might not seem like much, but it is poking holes in our understanding of how atoms formed during the Big Bang. … Fortunately, there’s one possible explanation for the discrepancy that hasn’t been ruled out yet—lithium is created and destroyed inside stars. It’s possible that scientists accurately predicted how much 6Li was produced during the Big Bang, and the rest was created later in stars. But for now, lithium is challenging our understanding of the Big Bang, big time. More: See also: National Geographic on the Big Bang “lithium shortage” Follow UD News at Twitter!

New Scientist: Life got started many times

From Penny Sarchet at New Scientist: Rather than springing into existence just once in some chemically blessed primordial pond, life may have had many origins. It could have got going over and over again in many different forms for hundreds of thousands of years, only becoming what we see today when everything else was wiped out it in Earth’s first ever mass extinction. In its earliest days on the planet, life as we know it might not have been alone. More. And it is not happening all around us now because … Oh wait! That is a Boltzmann brain floating above the inkjet printer… Is the Boltzmann brain a protected species? I better find out. Note: One could subscribe to Read More ›

Whale ultrasonics surprisingly old

From ScienceDaily: “Our study suggests that high-frequency hearing may have preceded the emergence of echolocation,” says Morgan Churchill of New York Institute of Technology in Old Westbury, New York. Churchill and his colleagues made their discovery in studies of a new fossil whale species (Echovenator sandersi) found in a drainage ditch in South Carolina. The researchers CT scanned the ancient whale’s remarkably complete fossilized ear and compared it to those of two hippos and 23 fossil and living whales. Those analyses uncovered many features found today in dolphins, which can hear at ultrasonic frequencies.More. Paper. (paywall) – Churchill et al. The Origin of High-Frequency Hearing in Whales.

Kirk Durston: Earth most special planet after all?

From Kirk Durston, in response to Ethan Siegel at Forbes, “Humanity May Be Alone In The Universe” (an unusual commonsensical approach to the question of extraterrestrial civilizations) at Contemplations: From a materialistic, evolutionary perspective, our technologically advanced civilization is almost certainly unique in the universe. Indeed, if the origin of life is so improbable that we should not even be here, then it seems we are faced with an interesting choice. The first option is to grant Koonin’s theory that we won a lottery against mind-staggering odds, requiring a near infinite number of unseen, untestable universes. The second option arises out of our observation that the universe and this particular planet seem to be incredibly fine-tuned to support life. It Read More ›

Schizophrenia arose only after Neanderthals?

From ScienceDaily: Schizophrenia poses an evolutionary enigma. The disorder has existed throughout recorded human history and persists despite its severe effects on thought and behavior, and its reduced rates of producing offspring. A new study may help explain why-comparing genetic information of Neanderthals to modern humans, the researchers found evidence for an association between genetic risk for schizophrenia and markers of human evolution.… “Our findings suggest that schizophrenia vulnerability rose after the divergence of modern humans from Neanderthals,” said Andreassen, “and thus support the hypothesis that schizophrenia is a by-product of the complex evolution of the human brain.” More.
