  1. Hi GeeKay, maybe I can help you with this. From what you are describing the movie content is defaulted to a high-res audio codec (with this move it is DTS HD Master Audio), while the other parts are not (they would be in standard PCM or DTS/Dolby). So your player or decoder (the Audio Video Receiver or the TV) cannot decode this codec. There are a couple of things that you can do: Set your Blu-ray player's audio output to PCM (aka LPCM) not bit stream. This *should* resolve the issue as it then outputs in a digital format that your AVR or TV can decode; But if your Blu-ray player can
  2. Thanks again Mike. The first page that you published is readable (together with the intro that I found), but the second one not. Don't worry too much as I think I got the gist of it. Also, the New Scientist Facebook page has a very good diagram/image relating to this article (plus the same intro) where they summarised their findings.
  3. Thanks Mike. I would love to read the rest of this.
  4. The next bit of news seems to fit nicely with the above:
  5. Source: Cosmos 23 October 2017. It seems like a pretty sensational claim...and title for the article..?
  6. Just a quick comment/question. It was initially predicted that Asteroid 2012 TC4, which is estimated to be 30m in size, will pass Earth at a distance of approx. 6,800kms (which is mighty close). They have since, only in July, recalculated and adjusted that estimate (based on more recent observations) to approx. 50,000kms. This asteroid will pass Earth this Thursday, merely 3 months after its orbit has been more accurately assessed. So, in theory, it could have been the other way around, no? If it was miscalculated the first time and we only find out that this asteroid was actually on route to
  7. I stand corrected, but afaik the RNA world hypothesis has been more theory and less evidential. This study claims to have demonstrated how small non-living molecules may have given rise to larger molecules that were capable of reproducing themselves, which according to them would have been a key event for life to take hold...in short: life from non-life (which probably would have been a more attention-grabbing title). Furthermore, apparently the size matters....the smallest molecule that exhibited self-ligation activity was a 40-nucleotide RNA. This very basic form of RNA also demonstrated the
  8. As reported on the Wits University website: Complex life evolved out of the chance coupling of small molecules “Life was a chance event, there is no doubt about that,” says Dr Pierre Durand from the Evolution of Complexity Laboratory in the Evolutionary Studies Institute at Wits University, who led a project to find out how exactly these molecules linked up with each other. Their results are published today in the journal Royal Society OS, in a paper entitled "Molecular trade-offs in RNA ligases affected the modular emergence of complex ribozymes at the origin of life”. Very simple
  9. Hi studiot, Thank you for the kind compliment. This article published by nature.com gives a more detailed overview of the findings, how it fits other evidence and the implications thereof: Oldest Homo sapiens fossil claim rewrites our species' history. Note that these were not new findings per se, but rather a more detailed gathering and processing of existing and additional evidence including more accurate dating of some of the remains. I do agree with you that the claim about a continental wide early dispersion of Homo sapiens based on similar types of stone tools found elsewhere, se
  10. June 1, 2017: The Laser Interferometer Gravitational-wave Observatory has made a third detection of gravitational waves, ripples in space and time, demonstrating that a new window in astronomy has been firmly opened. As was the case with the first two detections, the waves were generated when two black holes collided to form a larger black hole. Source
