Stephen Hawking Says Artificial Intelligence Will Take over Humanity in the Near Future





Excerpt from regaltribune.com

Technology has advanced so much that some scientists fear that one day robots will take over the world and humans will not be able to do anything about it.  
One of those scientists is Stephen Hawking, the most famous physicist and cosmologist in the world.
Hawking stated during a recent conference that robots and artificial intelligence in particular, could conquer humanity in the next 100 years.
The renowned scientist spoke at the Zeitgeist conference held in London, saying that computers will one day overtake us humans with their artificial intelligence and this could happen in less than 100 years.
Hawking added that if this happens, humans need to be sure that the robots have similar goals, or else.
But this is not the first time the author of “A Brief History of Time” made this kind of “doomy” statements about the future of humanity at the robotic hands of artificial intelligence.

At the beginning of this year, Stephen Hawking expressed his opinions on this matter, saying that artificial intelligence will advance so much that it could bring the end of human race.
Also, in an interview for BBC Hawking said that even though A.I. is not a threat to us humans at the present time, in the future the robots would get more intelligent, bigger and much stronger than their makers, the humans.
The scientist added that robots would start to redesign themselves and will evolve at an increasing rate that humans will not be able to keep the pace.
Hawking added that:
“Humans, who are limited by slow biological evolution, couldn’t compete, and would be superseded.”
And Hawking is not the only famous scientist who has a gloomy vision regarding our future.
Ellon Musk, Tesla Motors CEO, said that artificial intelligence poses a real threat to human race.

According to Musk, humans must be extremely careful about artificial intelligence, because it could turn out to be our “biggest existential threat”. Musk even compared A.I. with a “demon”.
However, not every scientist envisions a dark future for human race. While many think of artificial intelligence as the driving force behind robots, A.I. is also used to power many devices, such as smartphones, tablets, laptops and apps.
Artificial intelligence is also used to protect emails from receiving spam.
Giant companies like Google and Facebook are currently working on developing new systems, which will one day lead to advanced artificial intelligence.

Why the U.S. Gave Up on the Moon

Moon nearside



Excerpt from spacenews.com


Recently, several space advocacy groups joined forces to form the Alliance for Space Development. Their published objectives include a mention of obvious near-term goals such as supporting the commercial crew program, transitioning from use of the International Space Station to future private space stations and finding ways to reduce the cost of access to space.  What is notably missing from these objectives and those of many other space agencies, companies and advocacy groups is any mention of building a permanent settlement on the moon. It’s as if the lunar surface has become our crazy uncle that we all acknowledge exists but we’d prefer not to mention (or visit).  What made the next logical step in mankind’s progression beyond the bounds of Earth such a taboo subject?  If, as the Alliance for Space Development suggests, our nation wishes to move toward a path of permanent space settlements, the most logical step is our own planet’s satellite.

A base on the lunar surface is a better place to study space settlement than a space station or Mars for many reasons. Unlike a space station, the base does not have to contend with aerodynamic drag, attitude control issues or contamination and impingement from its own thrusters. Unlike a space station, which exists in a total vacuum and resource void, a lunar base has access to at least some surface resources in the forms of minerals, albeit fewer than might be available on Mars.  Many people naturally want to go directly to Mars as our next step. Even SpaceX has publicly stated this as its ultimate goal, with SpaceX President Gwynne Shotwell noting that “we’re not moon people.” However, Mars makes sense only if we think the technology is ready to safely support humans on another surface for long periods of time. Furthermore, budget restrictions make an ambitious goal like going immediately to Mars an unlikely prospect. Why are we afraid to take the seemingly necessary baby steps of developing the technology for a long-term base on a surface that can be reached in mere days instead of months?  The tendency to want to skip a lunar settlement is not a new phenomenon. Even before the first landing on the moon, U.S. and NASA political leadership was contemplating the future of manned space, and few of the visions involved a lunar base. The early space program was driven by Cold War competition with Moscow, and the kinds of ideas that circulated at the time involved milestones that seemed novel such as reusable spaceplanes, nuclear-powered rockets, space stations and missions to Mars.

If we are to have a program of manned space exploration, we must decide what the long-term goals of such a program should be, and we should align our actions with those goals.

And the next likely stop on that road is a permanent home just above our heads, on the surface of the brightest light in the night sky.

Biologists fear DNA editing procedure can alter human DNA




Excerpt from themarketbusiness.com

A group of biologists was alarmed with the use a new genome-editing technique to modify human DNA in a way that it can become hereditary.
The biologists worry that the new technique is so effective and easy to use that some physicians may push ahead with it before its safety can be weigh up. They also want the public to understand the ethical issues surrounding the technique, which could be used to cure genetic diseases, but also to enhance qualities like beauty or intelligence. The latter is a path that many ethicists believe should never be taken.


“You could exert control over human heredity with this technique, and that is why we are raising the issue,” said David Baltimore, a former president of the California Institute of Technology and a member of the group whose paper on the topic was published in the journal Science.

Ethicists have been concerned for decades about the dangers of altering the human germ line — meaning to make changes to human sperm, eggs or embryos that will last through the life of the individual and be passed on to future generations. Until now, these worries have been theoretical. But a technique invented in 2012 makes it possible to edit the genome precisely and with much greater ease. The technique has already been used to edit the genomes of mice, rats and monkeys, and few doubt that it would work the same way in people.

The new genome-editing technique holds the power to repair or enhance any human gene. “It raises the most fundamental of issues about how we are going to view our humanity in the future and whether we are going to take the dramatic step of modifying our own germline and in a sense take control of our genetic destiny, which raises enormous peril for humanity,” said George Daley, a stem cell expert at Boston Children’s Hospital and a member of the group.

The biologists writing in Science support continuing laboratory research with the technique, and few if any scientists believe it is ready for clinical use. Any such use is tightly regulated in the United States and Europe. American scientists, for instance, would have to present a plan to treat genetic diseases in the human germline to the Food and Drug Administration.

The paper’s authors, however, are concerned about countries that have less regulation in science. They urge that “scientists should avoid even attempting, in lax jurisdictions, germ line genome modification for clinical application in humans” until the full implications “are discussed among scientific and governmental organizations.”

Though such a moratorium would not be legally enforceable and might seem unlikely to exert global sway, there is a precedent. In 1975, scientists worldwide were asked to refrain from using a method for manipulating genes, the recombinant DNA technique, until rules had been established.

“We asked at that time that nobody do certain experiments, and in fact nobody did, to my knowledge,” said Baltimore, who was a member of the 1975 group. “So there is a moral authority you can assert from the U.S., and that is what we hope to do.”

Recombinant DNA was the first in a series of ever-improving steps for manipulating genetic material. The chief problem has always been one of accuracy, of editing the DNA at precisely the intended site, since any off-target change could be lethal. Two recent methods, known as zinc fingers and TAL effectors, came close to the goal of accurate genome editing, but both are hard to use. The new genome-editing approach was invented by Jennifer Doudna of the University of California, Berkeley, and Emmanuelle Charpentier of Umea University in Sweden.

Their method, known by the acronym Crispr-Cas9, co-opts the natural immune system with which bacteria remember the DNA of the viruses that attack them so they are ready the next time those same invaders appear. Researchers can simply prime the defense system with a guide sequence of their choice and it will then destroy the matching DNA sequence in any genome presented to it. Doudna is the lead author of the Science article calling for control of the technique and organized the meeting at which the statement was developed.

Though highly efficient, the technique occasionally cuts the genome at unintended sites. The issue of how much mistargeting could be tolerated in a clinical setting is one that Doudna’s group wants to see thoroughly explored before any human genome is edited.

Scientists also say that replacing a defective gene with a normal one may seem entirely harmless but perhaps would not be.
“We worry about people making changes without the knowledge of what those changes mean in terms of the overall genome,” Baltimore said. “I personally think we are just not smart enough — and won’t be for a very long time — to feel comfortable about the consequences of changing heredity, even in a single individual.”
Many ethicists have accepted the idea of gene therapy, changes that die with the patient, but draw a clear line at altering the germline, since these will extend to future generations. The British Parliament in February approved the transfer of mitochondria, small DNA-containing organelles, to human eggs whose own mitochondria are defective. But that technique is less far-reaching because no genes are edited.

There are two broad schools of thought on modifying the human germline, said R. Alta Charo, a bioethicist at the University of Wisconsin and a member of the Doudna group. One is pragmatic and seeks to balance benefit and risk. The other “sets up inherent limits on how much humankind should alter nature,” she said. 
Some Christian doctrines oppose the idea of playing God, whereas in Judaism and Islam there is the notion “that humankind is supposed to improve the world.” She described herself as more of a pragmatist, saying, “I would try to regulate such things rather than shut a new technology down at its beginning.”

Other scientists agree with the Doudna group’s message.
“It is very clear that people will try to do gene editing in humans,” said Rudolf Jaenisch, a stem cell biologist at the Whitehead Institute in Cambridge, Massachusetts, who was not a member of the Doudna group. “This paper calls for a moratorium on any clinical application, which I believe is the right thing to do.”
Writing in Nature last week, Edward Lanphier and other scientists involved in developing the rival zinc finger technique for genome editing also called for a moratorium on human germline modification, saying that use of current technologies would be “dangerous and ethically unacceptable.”

The International Society for Stem Cell Research said Thursday that it supported the proposed moratorium.

The Doudna group calls for public discussion but is also working to develop some more formal process, such as an international meeting convened by the National Academy of Sciences, to establish guidelines for human use of the genome-editing technique.

“We need some principled agreement that we want to enhance humans in this way or we don’t,” Jaenisch said. “You have to have this discussion because people are gearing up to do this.”

A Complete Guide to the March 20th Total Solar Eclipse

Excerpt from universetoday.com



The first of two eclipse seasons for the year is upon us this month, and kicks off with the only total solar eclipse for 2015 on Friday, March 20th.

And what a bizarre eclipse it is. Not only does this eclipse begin just 15 hours prior to the March equinox marking the beginning of astronomical spring in the northern hemisphere, but the shadow of totality also beats path through the high Arctic and ends over the North Pole.

Already, umbraphiles — those who chase eclipses — are converging on the two small tracts of terra firma where the umbra of the Moon makes landfall: the Faroe and Svalbard islands. All of Europe, the northern swath of the African continent, north-central Asia and the Middle East will see a partial solar eclipse, and the eclipse will be deeper percentage-wise the farther north you are .
2015 features four eclipses in all: two total lunars and two solars, with one total solar and one partial solar eclipse. Four is the minimum number of eclipses that can occur in a calendar year, and although North America misses out on the solar eclipse action this time ’round, most of the continent gets a front row seat to the two final total lunar eclipses of the ongoing tetrad on April 4th and September 28th.

How rare is a total solar eclipse on the vernal equinox? Well, the last total solar eclipse on the March equinox occurred back in 1662 on March 20th. There was also a hybrid eclipse — an eclipse which was annular along a portion of the track, and total along another — on March 20th, 1681. But you won’t have to wait that long for the next, as another eclipse falls on the northward equinox on March 20th, 2034.

Note that in the 21st century, the March equinox falls on March 20th, and will start occasionally falling on March 19th in 2044. We’re also in that wacky time of year where North America has shifted back to ye ‘ole Daylight Saving (or Summer) Time, while Europe makes the change after the eclipse on March 29th. It really can wreak havoc with those cross-time zone plans, we know…
The March 20th eclipse also occurs only a day after lunar perigee, which falls on March 19th at 19:39 UT. This is also one of the closer lunar perigees for 2015 at 357,583 kilometres distant, though the maximum duration of totality for this eclipse is only 2 minutes and 47 seconds just northeast of the Faroe Islands.

This eclipse is number 61 of 71 in solar saros series 120, which runs from 933 to 2754 AD. It’s also the second to last total in the series, with the final total solar eclipse for the saros cycle occurring one saros later on March 30th, 2033.



What would it look like to sit at the North Pole and watch a total solar eclipse on the first day of Spring? It would be a remarkable sight, as the disk of the Sun skims just above the horizon for the first time since the September 2014 equinox. Does this eclipse occur at sunrise or sunset as seen from the pole? It would be a rare spectacle indeed!

Safety is paramount when observing the Sun and a solar eclipse. Eye protection is mandatory during all partial phases across Europe, northern Asia, North Africa and the Middle East. A proper solar filter mask constructed of Baader safety film is easy to construct, and should fit snugly over the front aperture of a telescope. No. 14 welder’s goggles are also dense enough to look at the Sun, as are safety glasses specifically designed for eclipse viewing. Observing the Sun via projection or by using a pinhole projector is safe and easy to do.

Weather is always the big variable in the days leading up to any eclipse. Unfortunately, March in the North Atlantic typically hosts stormy skies, and the low elevation of the eclipse in the sky may hamper observations as well. From the Faroe Islands, the Sun sits 18 degrees above the horizon during totality, while from the Svalbard Islands it’s even lower at 12 degrees in elevation. Much of Svalbard is also mountainous, making for sunless pockets of terrain that will be masked in shadow on eclipse day. Mean cloud amounts for both locales run in the 70% range, and the Eclipser website hosts a great in-depth climatology discussion for this and every eclipse.

But don’t despair: you only need a clear view of the Sun to witness an eclipse!

Solar activity is also another big variable. Witnesses to the October 23rd, 2014 partial solar eclipse over the U.S. southwest will recall that we had a massive and very photogenic sunspot turned Earthward at the time. The Sun has been remarkably calm as of late, though active sunspot region 2297 is developing nicely. It will have rotated to the solar limb come eclipse day, and we should have a good grasp on what solar activity during the eclipse will look like come early next week.

And speaking of which: could an auroral display be in the cards for those brief few minutes of totality? It’s not out of the question, assuming the Sun cooperates.  Of course, the pearly white corona of the Sun still gives off a considerable amount of light during totality, equal to about half the brightness of a Full Moon. Still, witnessing two of nature’s grandest spectacles — a total solar eclipse and the aurora borealis — simultaneously would be an unforgettable sight, and to our knowledge, has never been documented!

We also put together some simulations of the eclipse as seen from Earth and space:




Note that an area of southern Spain may witness a transit of the International Space Station during the partial phase of the eclipse. This projection is tentative, as the orbit of the ISS evolves over time. Be sure to check CALSky for accurate predictions in the days leading up to the eclipse.

Let’s go back to the moon. No, Mars. No, the moon. The debate continues.




Excerpt from washingtonpost.com
By Christian Davenport 

To the moon again? Or Mars?
The questions have hung over NASA for years, and emerged again at a Senate committee hearing Tuesday.

Under President George W. Bush, the target was the moon. Under Obama, who said “we’ve been there before,” Mars became the mission.

But now as his term nears its end, there is some increasingly vocal criticism of that decision, saying there isn’t the funding or political will to get to Mars.

Focusing on Mars is a “flawed policy direction,” Scott Pace, the director of the Space Policy Institute at George Washington University testified on Tuesday. The shift in goals “blindsided” the international space community, he said. The moon “is the next logical target for all of our potential international partners.”

Russia has endorsed sending astronauts there, he said. China sent an unmanned rover to the moon, and unveiled designs for a new heavy rocket for deep space exploration. It even has plans to build its own space station. “Growing space powers such as the Republic of Korea and India have their own unmanned lunar ambitions,” Pace said, while adding that the private sector has also made huge advancements.

To regain its prominence in space, the United States should “lead a multinational program to explore the moon," Pace said.

If it doesn’t, he could imagine a “post-American space world, with a full range of manned and unmanned space activities, but without American leadership or even, in many cases, an American presence.”

Testifying before the same committee, Buzz Aldrin, the Apollo 11 pilot who was the second man to walk on the moon, said NASA is right to focus on going beyond the moon. "American leadership is more than simply getting one step ahead of our global competitors," he said. "American leadership is inspiring the world by consistently doing what no other nation is capable of doing."

Aldrin said he's working on a plan to get to Mars, and the next president should press ahead with the mission.

“I believe that early in the next administration, the nation must commit to developing a permanent presence on Mars,” he said.
With much fanfare, NASA has trumpeted its “Journey to Mars” campaign. And it has highlighted the unmanned test flight of the Orion capsule last year as evidence of its progress toward reaching the Red Planet. It is also developing a new heavy rocket, known as the Space Launch System, designed to go to Mars and deep space.

But critics have maintained that without the funding to support such an endeavor, the attempt is a little more than a public relations stunt. And while Sen. Ted Cruz (R-Texas) and other members the committee on Tuesday said they were committed to the new rocket, others have been less supportive.

“We made a wrong decision when we went down this road,” Rep. Dana Rohrabacher (R-Calif.) said at a hearing late last year.

A ‘bionic leaf’ that turns sunlight into fuel


Excerpt from cnbc.com

By Robert Ferris



The invention could pave the way for numerous innovations—by converting solar power into biofuels, it may help solve the vexing difficulty of storing unused solar energy, which is one of the most common criticisms of solar power as a viable energy source.
The process could also help make plastics and other chemicals and substances useful to industry and research.


The current experiment builds on previous research led by Harvard engineer Daniel Nocera, who in 2011 demonstrated an "artificial leaf" device that uses solar power to generate usable energy. 

Nocera's original invention was a wafer-like electrode suspended in water. When a current runs through the electrode from a power source such as a solar panel, for example, it causes the water to break down into its two components: hydrogen and oxygen. 

Nocera's device garnered a lot of attention for opening up the possibility of using sunlight to create hydrogen fuel—once considered a possible alternative to gasoline. 

But hydrogen has not taken off as a fuel source, even as other alternative energy sources survive and grow amid historically low oil prices. Hydrogen is expensive to transport, and the costs of adopting and distributing hydrogen are high. A gas station owner could more easily switch a pump from gasoline to biofuel, for example.


Now, Nocera and a team of Harvard researchers figured out how to use the bionic leaf to make a burnable biofuel, according to a study published Monday in the journal PNAS. The biologists on the team genetically modified a strain of bacteria that consumes hydrogen and produces isopropanol—the active ingredient in rubbing alcohol. In doing so, they successfully mimicked the natural process of photosynthesis—the way plants use energy from the sun to survive and grow.

This makes two things possible that have always been serious challenges for alternative energy space—solar energy can be converted into a storable form of energy, and the hydrogen can generate a more easily used fuel.


To be sure, the bionic leaf developments are highly unlikely to replace fossil fuels such as oil and natural gas any time soon—especially as the prices of both are currently so low. But it could be a good supplemental source. 

"One idea Dan [Nocera] and I share, which might seem a little wacky, is personalized energy" that doesn't rely on the power grid, biochemist Pamela Silver, who participated in the study, told CNBC in a telephone interview. 


Typically, people's energy needs are met by central energy production facilities—they get their electricity from the power grid, which is fed by coal- or gas-burning power plants, or solar farms, for example. Silver said locally produced energy could be feasible in developing countries that lack stable energy infrastructure, or could even appeal to people who choose to live off the grid.

"Instead of having to buy and store fuel, you can have your bucket of bacteria in your backyard," Silver said. 

Besides, the experiment was an attempt at proof-of-concept—the scientists wanted to demonstrate what could be done, Silver said. Now that they have mastered this process, further possibilities can be explored.  

"No insult to chemists, but biology is the best chemist there is, so we don't even know what we can make," said Silver. "We can make drugs, materials—we are just at the tip of the iceberg." 

The team hopes to develop many different kinds of bacteria that can produce all sorts of substances. That would mean, potentially at least, setting up the bionic leaf device and then plugging in whatever kind of bacteria might be needed at the moment.

For now, they want to increase the efficiency of the device, which is already much more efficient at photosynthesizing than plants are. Then they will focus on developing other kinds of bacteria to plug into the device.

"The uber goal, which is probably 20 years out," Silver said, "is converting the commodity industry away from petroleum."

Striking Similarities Between Brain Cells and Our Universe



The two pictures below illustrate the similarities. The top picture shows the neural network of a brain cell; the bottom picture shows the distribution of dark matter in the universe as simulated by Millennium Simulation.

The structures of the universe and the human brain are strikingly similar.

In the Eastern spiritual discipline of Daoism, the human body has long been viewed as a small universe, as a microcosm. As billion-dollar investments are made in the United States and Europe to research brain functioning, the correlations between the brain and the universe continue to emerge.

The two pictures below illustrate the similarities. The top picture shows the neural network of a brain cell; the bottom picture shows the distribution of dark matter in the universe as simulated by Millennium Simulation.

The pictures show a structural similarity in terms of connections and distribution of matter in the brain and in the universe. The photo on the left is a microscopic view, the one on the right is a macroscopic view.

The brain is like a microcosm.

A study conducted by Dmitri Krioukov of the University of California and a team of researchers published in Nature last year shows striking similarities between neural networks in the brain and network connections between galaxies.

Krioukov’s team created a computer simulation that broke the known universe down into tiny, subatomic units of space-time, explained Live Science. The simulation added more space-time units as the history of the universe progressed. The developing interactions between matter in galaxies was similar to the interactions that comprise neural networks in the human brain.
Physicist Kevin Bassler of the University of Houston, who was not involved in the study, told Live Science that the study suggests a fundamental law governing these networks.

In May 2011, Seyed Hadi Anjamrooz of the Kerman University of Medical Sciences and other Iranian medical scientists published an article in the International Journal of the Physical Sciences on the similarities between cells and the universe. They explain that a black hole resembles the cell nucleus. A black hole’s event horizon—a sort of point of no return where the gravitational pull will suck objects into the black hole—also resembles the nuclear membrane.

The event horizon is double-layered, as is the nuclear membrane. Much like the event horizon, which prevents anything that enters from leaving, the nuclear membrane separates cell fluids, preventing mixing, and regulates the exchange of matter between the inside and outside of the nucleus. Black holes and living cells also both emit pockets of electromagnetic radiation, among other similarities.

The researchers wrote: “Nearly all that exists in the macrouniverse is mirrored in a biological cell as a microuniverse. Simply put, the universe can be pictured as a cell.”
