He calls it a "very sexy curve on a graph" and it will be a game changer.  Highly recommended article on the economics of energy from +Mark Bruce and +David Fuchs

When we think of the huge role our concentrated energy sources play in politics, war, and the economy, it's amazing. Adequate levels of distributed energy really will change everything.

I am not sure I grasp the conclusion; if the petroleum industry devalues long-term reserves, what effect will this have on their business practices? In fact, petroleum is useful for more than just energy production but the value over business cycle time horizons must decline if other forms of energy production are competing.

First, make it right. Then, make it fast.  Obscuring code to make it run faster isn't always necessary or desirable, but when it matters - like creating Burrows-Wheeler transforms from billion-base pair genomes - Pearls of Functional Algorithm Design looks like it would be an interesting reference. 

Thanks +Claudia Doppioslash for sharing. :)

Imagine a world without hate.   Humans are capable of such wonderful things, but there remains a side to us that too easily distances ourselves from others.  Efforts to dehumanize and marginalize some of us, reduce us all. 

Our thoughts are with the family and friends of those hurt and killed in Overland Park and with all those consumed with anger and tortured by hatred.

Happiness Science. Practical suggestions for how to quiet our inner critics and saboteurs - and activate our innate Jedi sage superpowers. Great talk by Professor +Shirzad Chamine on "Positive Intelligence" and the science of increasing happiness and performance.

The talk includes simple, actionable strategies for making a positive difference.  No equipment needed - you can start with just 10 seconds! (On your own - or with a friend.)  :) 

It's hard enough to fight enemies with outposts in our brains, harder still, when we can't see them.  The website includes a quick quiz to find out what we might be dealing with.

Stanford Professor Shirzad Chamine is author of the New York Times bestseller Positive Intelligence. His work exposes 10 well-disguised mental saboteurs and shares how to defeat them. According to Chamine, "positive intelligence" measures the percentage of time our mind serves us as opposed to sabotaging us.

Might be time to update 4-digit pin codes, too. :)

The chart shows the relative frequency of various 4-digit pin codes. Sequences, 4-digit years, and 4-digit day-month combinations are obvious favorites. :)

Beautiful abstract art?

Rather this is a graphical representation of the frequency of four digit PIN codes. On the x-axes we have the first two PIN digits from 00.. to 99.., on the y-axes we have the last two digits from ..00 to ..99. Popular PIN codes include the yellow diagonal, PIN codes of the form XYXY, and even more bright XXXX. The vertical yellow line are PIN codes marking a year, mostly between the years 1930-2010. The yellow blob on the lower left are US formatted calendar days from 01/01 to 12/31 (you can even see how many days each month has). Also singleton yellow dots can be explained.

Anyway, it is beautiful, in my opinion.

Great catch  +Bill DeWitt -  8068 got the disproportionately least amount of  love:
 
"In my dataset the answer is  8068  with just 25 occurrences in 3.4 million (this equates to 0.000744%, far, far fewer than random distribution would predict, and five orders of magnitude behind the most popular choice)."

No idea why though...what's so bad about 8068?  

8080 is on the popular diagonal since it repeats... nothing especially good or bad about Intel's notable 8086. :)

Earth-size and habitable-zone. :) A good candidate for liquid water and rocky terrain.  We don't know yet what the composition is - but we've seen that combination before - and it's given rise to some of the most complex, beautiful, insightful, and curious parts of the known Universe.

NASA's Kepler Mission Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star!
April 17, 2014: This artist's concept depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone. Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone"—the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth.
"The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth," said Paul Hertz, NASA's Astrophysics Division director at the agency's headquarters in Washington. "Future NASA missions, like the Transiting Exoplanet Survey Satellite and the James Webb Space Telescope, will discover the nearest rocky exoplanets and determine their composition and atmospheric conditions, continuing humankind's quest to find truly Earth-like worlds."

Although the size of Kepler-186f is known, its mass and composition are not. Previous research, however, suggests that a planet the size of Kepler-186f is likely to be rocky.

"We know of just one planet where life exists -- Earth. When we search for life outside our solar system we focus on finding planets with characteristics that mimic that of Earth," said Elisa Quintana, research scientist at the SETI Institute at NASA's Ames Research Center in Moffett Field, Calif., and lead author of the paper published today in the journal Science. "Finding a habitable zone planet comparable to Earth in size is a major step forward."

Kepler-186f resides in the Kepler-186 system, about 500 light-years from Earth in the constellation Cygnus. The system is also home to four companion planets, which orbit a star half the size and mass of our sun. The star is classified as an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy.
"M dwarfs are the most numerous stars," said Quintana. "The first signs of other life in the galaxy may well come from planets orbiting an M dwarf."

Kepler-186f orbits its star once every 130-days and receives one-third the energy from its star that Earth gets from the sun, placing it nearer the outer edge of the habitable zone. On the surface of Kepler-186f, the brightness of its star at high noon is only as bright as our sun appears to us about an hour before sunset.

"Being in the habitable zone does not mean we know this planet is habitable. The temperature on the planet is strongly dependent on what kind of atmosphere the planet has," said Thomas Barclay, research scientist at the Bay Area Environmental Research Institute at Ames, and co-author of the paper. "Kepler-186f can be thought of as an Earth-cousin rather than an Earth-twin. It has many properties that resemble Earth."

The four companion planets, Kepler-186b, Kepler-186c, Kepler-186d, and Kepler-186e, whiz around their sun every four, seven, 13, and 22 days, respectively, making them too hot for life as we know it. These four inner planets all measure less than 1.5 times the size of Earth.
The next steps in the search for distant life include looking for true Earth-twins -- Earth-size planets orbiting within the habitable zone of a sun-like star -- and measuring the their chemical compositions. The Kepler Space Telescope, which simultaneously and continuously measured the brightness of more than 150,000 stars, is NASA's first mission capable of detecting Earth-size planets around stars like our sun.

Ames is responsible for Kepler's ground system development, mission operations, and science data analysis. NASA's Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development. Ball Aerospace & Technologies Corp. in Boulder, Colo., developed the Kepler flight system and supports mission operations with the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. The Space Telescope Science Institute in Baltimore archives, hosts and distributes Kepler science data. Kepler is NASA's 10th Discovery Mission and was funded by the agency's Science Mission Directorate.

The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach.  The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.

For a long-term view, better to attach our loyalty to DNA-based life, rather than to humanity.  Having said which, computational life forms might stand a much better chance - it can readily sit out long journeys, and it can fork exact copies (if that's advantageous)

Literally eating people alive : No kidding. We have heard of Naeglaria fowleri, the brain eating amoeba found in water. Now there is new research that shows that the parasite Entamoeba histolytica , which was earlier thought to kill human cells by toxins, actually eats them while they are still alive.

Article Extract: It used to be thought that the parasite Entamoeba histolytica killed human cells with toxins and only ate them once they were dead--and that during its meals, it would eat cells by engulfing them whole, like other amoebas. But a new study shows that these parasites instead chomp on human cells while they are still alive, taking little bites until the cells die and then moving on.

“This process of nibbling of cells went unrecognized by everyone in this field, including me, for over a hundred years,” study co-author and infectious disease specialist William Petri of the University of Virginia in Charlottesville told Science. This habit of chewing bits of live cells in this way and moving on is remarkably strange, and basically unprecedented. "The ingestion of live cell material and the rejection of corpses illuminate a stark contrast to the established model of dead cell clearance in multicellular organisms."

Mostly Microbe. Our microbes may be essential to our health - and our happiness.  For every human gene in our genome, there are 100 bacterial genes in our microbiome; in many ways we are "more microbe than human."

(+Michael Pollan May 15, 2013)

Excerpt 1: Gut microbes may have a powerful influence on metabolism:

Justin Sonnenburg, a microbiologist at Stanford, suggests that we would do well to begin regarding the human body as “an elaborate vessel optimized for the growth and spread of our microbial inhabitants.” This humbling new way of thinking about the self has large implications for human and microbial health, which turn out to be inextricably linked. Disorders in our internal ecosystem — a loss of diversity, say, or a proliferation of the “wrong” kind of microbes — may predispose us to obesity and a whole range of chronic diseases, as well as some infections. “Fecal transplants,” which involve installing a healthy person’s microbiota into a sick person’s gut, have been shown to effectively treat an antibiotic-resistant intestinal pathogen named C. difficile, which kills 14,000 Americans each year. (Researchers use the word “microbiota” to refer to all the microbes in a community and “microbiome” to refer to their collective genes.) ... A similar experiment was performed recently on humans by researchers in the Netherlands: when the contents of a lean donor’s microbiota were transferred to the guts of male patients with metabolic syndrome, the researchers found striking improvements in the recipients’ sensitivity to insulin, an important marker for metabolic health. Somehow, the gut microbes were influencing the patients’ metabolisms.

Excerpt 2:  Thinking with your gut (microbes) :)

Our gut bacteria also play a role in the manufacture of substances like neurotransmitters (including serotonin); enzymes and vitamins (notably Bs and K) and other essential nutrients (including important amino acid and short-chain fatty acids); and a suite of other signaling molecules that talk to, and influence, the immune and the metabolic systems. Some of these compounds may play a role in regulating our stress levels and even temperament: when gut microbes from easygoing, adventurous mice are transplanted into the guts of anxious and timid mice, they become more adventurous. The expression “thinking with your gut” may contain a larger kernel of truth than we thought.
