  • Not so science fiction after all, the internet could out-evolve humanity
    we do not necessarily feel that we are the mere flesh bots of our digital overlords the merging of humans with the digital world has now passed the point of no return In biological terms fusions like these between two unrelated organisms are called symbioses In nature all symbioses have the potential to turn into a parasitic relationship where one organism fares much better than the other We need to start thinking about the internet as an organism that can evolve Whether it cooperates or competes with us is cause for considerable concern Explore further Scientists show how social interaction and teamwork lead to human intelligence Source The Conversation 93 shares feedback to editors This article was originally published on The Conversation Read the original article Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 Physicists create first photonic Maxwell s demon 14 hours ago 3 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 more Phys org on facebook Relevant PhysicsForums posts Should I take an extra year as an undergade student Jul 13 2015 Poincaré s Space Dilemma Jul 13 2015 Newbie question The Big Bang The Observable Universe and time Jul 13 2015 Force on a body due to pressure of a fluid Jul 13 2015 Computer Engineering Electrical Eng Computer Science Jul 13 2015 Does 1 mole of all gas exert equal pressure Jul 13 2015 More from Physics Forums The Fusion of Science and Community Related Stories Scientists show how social interaction and teamwork lead to human intelligence April 19 2012 Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation and teamwork shedding new light on the origins of what it means to be human The study appears online Long term storage of digital information in DNA is possible February 9 2015 It is evident from samples from mammoths bears and other fossils sequenceable DNA can last up to several hundred thousand years But one does not necessarily need fossil bones as capsules of silica glass spheres can do Digital rights group alleges Google invades student privacy December 2 2015 Google is being accused of invading the privacy of students using laptop computers powered by the Internet company s Chrome operating system Hello Kitty owner Sanrio says fan site security leak fixed December 23 2015 The Japanese company that owns the Hello Kitty brand said it has fixed a security leak in an online fan site for the famous character that compromised the personal information of 3 3 million users Governments urged to support scrambling digital data January 11 2016 An open letter posted on Monday by Internet freedom advocates called on governments to back tough encryption of digital data to keep people s information private Could the

  • All five bright planets come together in the morning sky
    all the way across to the eastern horizon As early February comes around I also highly recommend checking out the flight path of the International Space Station via websites such as Heavens Above or NASA s Spot the Station The Station will be flying morning passes over Australia during that time and current predictions for each capital city have it travelling right through or near the line of planets for example Darwin February 3 Brisbane February 5 Perth February 6 Sydney February 7 Canberra February 7 Adelaide February 8 Melbourne February 9 and Hobart February 11 The predictions can change slightly so best to check the websites closer to the date and be sure to enter your precise location to obtain the most accurate timing for the pass Finally there s still more to come This August the five planets will be together again visible in the evening sky so stay tuned for more planet watching in 2016 Explore further STAR TRAK for February 2012 Source The Conversation 5941 shares feedback to editors This article was originally published on The Conversation Read the original article Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 Physicists create first photonic Maxwell s demon 14 hours ago 3 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 more Phys org on facebook Relevant PhysicsForums posts Green shift for Andromeda 3 hours ago Survival on Mars 4 hours ago How far outward can we rule out intelligent life 7 hours ago Sound of GW150914 10 hours ago How exactly do SMBHs in the center of galaxies form 10 hours ago Our Beautiful Universe 11 hours ago More from Astronomy and Astrophysics Related Stories STAR TRAK for February 2012 February 2 2012 As evening twilight fades during February the two brightest planets Venus and Jupiter will highlight the sky as they come into view in the southwest Dance of the planets in the evening sky February 19 2015 Armagh Observatory reports that the next two weeks provide a rare opportunity to observe the planets Venus Mars and Uranus in the western evening sky after sunset and the bright planet Jupiter rising high in the East about Close approach of Venus and Jupiter visible in evening sky June 15 2015 Armagh Observatory reports that the next two weeks will provide an interesting opportunity to observe the brightest planet Venus and the largest planet Jupiter as they move towards one another in the evening twilight Jupiter Venus and Mars stand proud in the morning sky October 14 2015 Armagh Observatory reports that the next three weeks from mid October to the first week of November will provide an interesting opportunity to observe a dance of the brightest planets Venus Jupiter and Mars in the morning Dawn triangle of planets

  • Rapid, affordable energy transformation possible, study says
    new paper suggests the United States could cut total CO2 emissions 31 percent below 2005 levels by 2030 by making changes only within the electric sector even though the electrical sector represents just 38 percent of the national CO2 budget These changes would include rapidly expanding renewable energy generation and improving transmission infrastructure We are doing it And we can do it without nukes KBK 3 7 5 9 Jan 25 2016 Fixing the economy fixing the environment fixing the social structure and any other fixing has always been highly viable The problem is elite oligarchy in the political military police and financial systems Those are the stumbling blocks None of those groups or associations will work to fix the US or the planet unless they remain as top dog They have shown over centuries that they are willing to sacrifice and malign anyone s life in the pursuit of power and in inter relational wars they have among themselves all at the expense of the population of the world and earth habitat Complete control top dog at any price If one does not come at the problem with an integral understanding of the push from elite hidden power groups who commit to various forms of war at the drop of a hat to maintain power then this situation will never be solved and most of us will be dead Your target therefore first and foremost is hidden elite power structure david king 1 8 5 5 Jan 25 2016 Actually we could probably meet those goals in the western US almost entirely through energy conservation without doing one more wind or solar farm It s all a matter of putting the incentives in the right place Take the grid down for a couple of hours and see how folks scramble to figure out ways to charge their cell phones and power up their furnaces Cut natural gas supplies for a week and see how many start piling in insulation and tightening up air gaps Lord jag 5 5 5 Jan 25 2016 That sounds like the Northeast Blackout of 2003 It really didn t change much When the power came back on everyone resumed their carbon consuming lives Its becoming quite obvious that renewable is new cheaper and getting cheaper every year while non renewables are more expensive every year It s not about price it s about controlling power jeffensley 2 3 5 3 Jan 25 2016 The problem is elite oligarchy in the political military police and financial systems I disagree The issue is inertia It s simpler to work with what we already have than do a complete transition and we re humans we like simple Interesting study though Once it s shown to be economically viable it s only a matter of time And it s easy to say Yeah we ll just put HVDC lines across the country but models don t account for public backlash when they discover one of these ugly things is coming across their property and the government wants to acquire it or have them lease it out for the public good gkam 4 5 4 Jan 25 2016 It really didn t change much When the power came back on everyone resumed their carbon consuming lives True but we had very few alternatives then and even less knowledge of their advantages Eikka 3 4 5 5 Jan 25 2016 We are doing it And we can do it without nukes So who exactly is doing it Who s building the new cross continent HVDC grid Who is this we Answer nobody Especially not you Besides you also forgot that this system would be exactly the kind of big energy solution that you re always arguing against on the point of local energy independence You re applying double standards Please do build it don t just pretend and take credit for what you haven t actually done Eikka 3 5 5 6 Jan 25 2016 Yeah we ll just put HVDC lines across the country but models don t account for public backlash when they discover one of these ugly things is coming across their property That s the practical problem The theoretical cost is low assuming you don t have to pay people to move their house out of the way Of course you can confiscate property by the power of the state but that ll be a political suicide That s the same reason why the North South power corridor in Germany is a decade late and still under planning It s NIMBY all the way down from Denmark to Austria It s easy for politicians to promise yet more subsidies to the green power industry for votes but when it comes to the actual infrastructure to make use of it nobody wants to put their foot down because it makes a lot of people angry That s why evolution works better than revolution gkam 2 2 5 6 Jan 25 2016 The world must look REALLY scary from under your bed Yes WE the folk in the energy business where I used to work are doing it I do my part with an electric vehicle and PV on the roof being retired Do you operate a coal powerplant Run your car on coal What BTW this is a revolution only to those unaware of the decades of studies and work which has been going into it It is only the initial actualization which is now apparent Eikka 4 5 4 Jan 25 2016 There s a parallel to this study in the European DESERTEC project where a HVDC supergrid would extend all the way from North Africa to Norway https en wikipe Desertec Problem is almost all the shareholders in the project have bailed out The problem is political North Africa is too unstable for Europe to rely on Eikka 4 5 4 Jan 25 2016 Yes WE the folk in the energy business where I used
