General interest

I have recently posted a new video presentation on my YouTube channel. In the video I talk about some of the reasons why I think the debate over Intelligent Design and biological origins is of great significance. Aside from just being a fascinating area, it has many implications in several areas of life. This video, while far from perfect, is a big step up from my last few videos. I’ve done a fair amount of editing on this one, and took time to make it a little more professional, with music, slides, and photos. I hope you enjoy it, and it gets you thinking a little about why this topic is of importance to you also. Why the Question of Read More ›

Here is a model of the top 15 “countries” across the span from the Agricultural Revolution onwards: Food for thought on trends and implications. Notice, the principle that trends (like pie-crusts) are made to be broken. To truly predict, we need dynamics and some reasonable idea of contingencies. Don’t forget to take reconstructions of the deep unrecorded past and future projections with a grain of salt. END

Let’s read the Nature abstract: Nature (2019) Article | Published: 15 May 2019 Total synthesis of Escherichia coli with a recoded genome Julius Fredens, Kaihang Wang, Daniel de la Torre, Louise F. H. Funke, Wesley E. Robertson, Yonka Christova, Tiongsun Chia, Wolfgang H. Schmied, Daniel L. Dunkelmann, Václav Beránek, Chayasith Uttamapinant, Andres Gonzalez Llamazares, Thomas S. Elliott & Jason W. Chin AbstractNature uses 64 codons to encode the synthesis of proteins from the genome, and chooses 1 sense codon—out of up to 6 synonyms—to encode each amino acid. Synonymous codon choice has diverse and important roles, and many synonymous substitutions are detrimental. Here we demonstrate that the number of codons used to encode the canonical amino acids can be reduced, Read More ›

Of course, any high intensity light source is potentially damaging to the retina; that’s why we should not look directly at the sun or try to view a solar eclipse directly. Electric arc welding and lasers — including laser pointers — are also hazardous. Retinal burns are painless and permanent. It is believed that that is how Galileo went blind, looking at the sun too much. So, obviously LED’s that are high intensity come with the automatic warning about any high intensity light source. However, white light LED technology is based on a blue or UV LED with a phosphor that fluoresces with the missing colours to make white, i.e. red and green. Under addition of light, red and green Read More ›

According to news reports, already over US$ 1 billion has been pledged towards rebuilding Notre Dame: BTW: after the fire, a video tour: In today’s ever so polarised age [currently awaiting the infamous redacted Mueller Report on a two-year investigation into US President Trump], it is unsurprising that we see for example in Rolling Stone: . . . for some people in France, Notre Dame has also served as a deep-seated symbol of resentment, a monument to a deeply flawed institution and an idealized Christian European France that arguably never existed in the first place. “The building was so overburdened with meaning that its burning feels like an act of liberation,” says Patricio del Real, an architecture historian at Harvard Read More ›

The ID issue has long been a focal point for intense, often deeply polarised debate on our origins and world roots as informed by science. Science, being a major source of knowledge and understanding about our world, which also energises technological innovation and economic growth. Science is often treated as though it is the grounds for seeing evolutionary materialism as effectively self evidently true but crucially depends on our being responsibly and rationally sufficiently free to think logically, establish mathematics as a domain of rationally grounded truth about abstract structures and quantities that are necessary for any possible world, and more. Such already deeply challenges the world-picture painted by the magisterium of lab coat-clad atheists. That is only a gateway Read More ›

Here’s a new paper form Nature Communications describing a discovery of a new geometric shape that is apparently found only in curved epithelial cells. I find it intriguing that this shape is entirely new, not found elsewhere in nature, but now coined “scutoids” by the authors, and is proposed as making “possible the minimization of the tissue energy and stabilize three-dimensional packing.” From the abstract: “The detailed analysis of diverse tissues confirms that generation of apico-basal intercalations between cells is a common feature during morphogenesis. Using biophysical arguments, we propose that scutoids make possible the minimization of the tissue energy and stabilize three-dimensional packing. Hence, we conclude that scutoids are one of nature’s solutions to achieve epithelial bending. Our findings Read More ›

The Meltdown-Spectre processor architectural flaw crisis we have been monitoring has deepened as Intel has to patch its initial patch: . . . and as a first wave of the inevitable lawsuits hits. Here, we clip one in San Francisco:   NB: Comment 3 below links and clips documentation AMD has been sued over its response to Spectre. Where also, The Register further reports that there are problems with embedded systems using microprocessors and microcontrollers: >>Patches for the Meltdown vulnerability are causing stability issues in industrial control systems. SCADA vendor Wonderware admitted that Redmond’s Meltdown patch made its Historian product wobble. “Microsoft update KB4056896 (or parallel patches for other Operating System) causes instability for Wonderware Historian and the inability to Read More ›

Let’s follow up our earlier Sci-Tech Newswatch on the Meltdown-Spectre MPU architecture flaw issue. (We see here just how hard it is to create a robust, complex design that can readily be adapted to changes in the environment. Besides, a heads up on a big but under-reported story is helpful.) In a new Jan 15, 2018 report on Meltdown in The UK’s The Register, we may read: >>Patches for the Meltdown vulnerability are causing stability issues in industrial control systems. SCADA vendor Wonderware admitted that Redmond’s Meltdown patch made its Historian product wobble. “Microsoft update KB4056896 (or parallel patches for other Operating System) causes instability for Wonderware Historian and the inability to access DA/OI Servers through the SMC,” an advisory Read More ›
