Great Discoveries Channel: Sci, Space, Tech
In Episode Seven, The Clean Room, Neil deGrasse Tyson starts our journey traveling to the shallow seas that formed what we now know as the Grand Canyon a billion years ago in what then was the Precambrian Epoch to find the only kind of life on the planet: blue-green bacteria. Oxygen, one of the by-products of photosynthesis by microbes such as cyanobacteria and their descendants -including algae and higher plants, transformed the Precambrian Earth and made possible the evolution of more complex organisms. Continue reading "'Cosmos: A Spacetime Odyssey' (Sunday's Episode 7) --Preview & Background for "The Clean Room"" » Continue reading "Kepler-Mission Update -- NASA's Scientists' Insights on Discovery of 1st Earth-Sized Planet in Habitable Zone" » Five years ago today, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies to find planets around other stars within a field of view 1/400th the size of the Milky Way in search of potentially habitable worlds.

528Hz Frequency healing the Gulf Perdido Bay, Alabama—A series of sounds played to oil polluted water from the Gulf of Mexico has “miraculously” cleared test samples of the deadly petrochemicals, says a well known Canadian researcher. According to John Hutchinson, an electro-magnetic energy expert from Vancouver, B.C., Canada, a selection of “music” has helped purify poisoned water. The frequencies included the “sound of Jupiter,” recently recorded by NASA, vibrating close to 528Hz frequency. That sound energy has been determined to match the color greenish-yellow–the heart of the rainbow, the electromagnetic color spectrum, celebrated by the botanical world, according to Dr. Leonard Horowitz, who has published most on that pure tone.

Scientists Reveal How We'd Really Die If A Meteor Hit Earth In the event that a meteor were to hit our planet, most of us would probably assume we’d die from the sheer impact of the huge rock, or the intense pressure caused by such an event. Nah. While those things would certainly kill a considerable amount of people, what we really need to be worried about are the high-intensity winds. Huh? Giphy Yeah. OMG Facts When you repeat a word continuously and it loses meaning, it’s called “jamais vu.” Jamais vu means “never seen” and is considered the opposite or reverse of déjà vu. It means the sense of unfamiliarity in the presence of very familiar things, situations or words. It’s been observed and estimated that 60% of people have experienced jamais vu before. Jamais vu was first recognized about 100 years ago and musicians are prone to getting it while playing a familiar passage.

Singularity The term “Singularity” had a much narrower meaning back when the Machine Intelligence Research Institute was founded. Since then the term has acquired all sorts of unsavory connotations. The kind of Singularity I work on has little to do with Moore’s Law. So forget the word; here’s the issue:

Previous What's New in Cosmology's Herschel out of Helium 29 April 2013 - The European Space Agency's Herschel Space Observatory has run out of liquid helium coolant, nearly 4 years after its launch . This means that there are currently no space infrared telescopes operating at wavelengths longer than the 4.5 μm channel of the Spitzer Space Telescope . First Cosmology Results from Planck 31 March 2013 - Planck released its first cosmology results today. Technical preprints are available here .

Q&A on Bright Light Therapy What is light therapy for winter symptoms, and how is it delivered? Light therapy involves exposure to intense levels of light under controlled conditions. The recommended light therapy system consists of a set of fluorescent bulbs installed in a box with a diffusing screen, and set up on a table or desk top at which one can sit comfortably for the treatment session. Treatment consists simply of sitting close to the light box, with lights on and eyes open. Hissing-Meteor Mystery May Finally Be Solved The bizarre hissing and rustling noises that some fireballs make may finally have an explanation. These faint sounds are probably created when bright pulses of light from the meteors heat up certain objects on the ground below, a new study reports. These objects — for example, leaves or hair — radiate thermal energy into the nearby air, producing pressure waves that generate a variety of sounds. "I think our answer is pretty solid," said study co-author William Sweatt, a researcher at Sandia National Laboratories in New Mexico. [Listen to the Spooky Meteor Sounds! (Video)]

Severe nuclear reactor accidents likely every 10 to 20 years, European study suggests Western Europe has the worldwide highest risk of radioactive contamination caused by major reactor accidents. Catastrophic nuclear accidents such as the core meltdowns in Chernobyl and Fukushima are more likely to happen than previously assumed. Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred, scientists at the Max Planck Institute for Chemistry in Mainz have calculated that such events may occur once every 10 to 20 years (based on the current number of reactors) -- some 200 times more often than estimated in the past. The researchers also determined that, in the event of such a major accident, half of the radioactive caesium-137 would be spread over an area of more than 1,000 kilometres away from the nuclear reactor. Their results show that Western Europe is likely to be contaminated about once in 50 years by more than 40 kilobecquerel of caesium-137 per square meter.

Rationality Over the last several decades, science has developed a new picture of how we succeed or fail to seek true beliefs and achieve our goals. The heuristics and biases program in cognitive psychology has exposed dozens of major flaws in human reasoning, and along with them, insight into the mental processes that produce these flaws. Bayesian probability theory and decision theory have been used in increasingly powerful statistical methods and machine learning algorithms; I believe that they also provide a lens through which to view everyday life. Evolutionary psychology and social psychology are also telling us new and disturbing things about human nature – can we, now knowing, do any better? The vast bulk of my writings on rationality are contained on the Less Wrong community blog – follow the link to see some of my recommended posts. {*style:<ul>*} {*style:<li>*}{*style:<h3>*}{*style:<a href=' Virtues of Rationality{*style:</a>*}{*style:</h3>*} {*style:<br>*}The first virtue is curiosity.

Jonathan McDowell's Home Page In addition to my day job I carry out research into the history of the space program and write an email-distributed newsletter, Jonathan's Space Report . From 1993 to 2010 I wrote a monthly column for Sky and Telescope Magazine which I still recommend as a great source of astronomy info. I've also appeared on TV around the world pontificating on the latest goings-on in space and have now ventured into the podcastosphere.

Seasonal Affective Disorder and Light Therapy “Mehr Licht!” cried out Goethe, the great German writer, as he was dying, “More light!” In these two words he encapsulated (albeit inadvertently) the essential principle underlying the major treatment for seasonal affective disorder (SAD). Alien Abductee Draws Exact Star Map Of The Alien's Home Constellation: Zeta Reticuli Claims of having been abducted by extraterrestrials are often scoffed at due to the lack of evidence presented. However, some claims of alien abduction do involve actual evidence of the abductee's claims. In the early 1960s, a woman who claimed to have experienced an alien abduction drew a map of a star system and showed it to scientists. 'Life' gene missing on volcanoes 11 June 2012Last updated at 19:50 ET A gene thought previously to be present in all life on earth is missing in microbes in volcanoes A gene thought previously to be present in all life on earth is missing in microbes living in boiling acid near the summits of volcanoes. The protein, thought to be one of the fundamental building-blocks of life, is not present in certain volcanic single cell organisms. St Andrews university scientists studied archaea, which are similar to bacteria but have a separate origin.

02002-02029 (27 years): By 2029 no computer - or &machine intelligence& - will have passed the Turing Test. - Long Bets - StumbleUpon The Significance of the Turing Test. The implicit, and in my view brilliant, insight in Turing's eponymous test is the ability of written human language to represent human-level thinking. The basis of the Turing test is that if the human Turing test judge is competent, then an entity requires human-level intelligence in order to pass the test.
