Hawking: Humans may lose to machines in a hundred years or so without even knowing it.






Excerpt from esbtrib.com


Stephen Hawking, the scientist and not Stephen King, the novelist has made some dire predictions about the coming conquest of humans by their own creations, robots. King can write something about this in effect but he will have a hard time surpassing the number one robot movie of all time, the terminator.
Humans’ dependence on electronic technology to make their life comfortable and much easier may one day backfire on them. The scientist said that humans have become so complacent that they may not survive in the future.
In a conference held just recently, Hawking noted that robots and artificial intelligence could take over the world and conquer mankind in the next 10 decades. By 2115, the world will cease to exist as we know it today. While speaking at the Zeitgeist conference held in London, Hawking explained that humans need to come to terms with how they should go forward and not fall into complacency with how robotics and artificial intelligence are taking over without them even knowing it.
“One can imagine such technology outsmarting financial markets, out-inventing human researchers, out-manipulating human leaders, and developing weapons we cannot even understand. Whereas the short-term impact of AI depends on who controls it, the long-term impact depends on whether it can be controlled at all”, he continued.
(Hawking continued to explain3ed that technology advancements that outsmarts financial markets, creating more and better inventions than humans, putting world leaders  under its influence and coming up with advanced weaponry are slowly putting humans at a disadvantage. Researches should be made considering what AI would mean for humans.
.Creation of Ai would be in no doubt the greatest achievement of what humans can do if they can do it. It might also their last act if they’re not careful about it.
Humans’ have notoriously slow biological evolution and their ability to challenge the AI is almost none existent compared to what the machines can muster. Elon Musk agrees with Hawking about the dangers posed by AIs.

How to make oxygen on Mars: Nasa plans to use oxygen cocktail to support human colony

An Indiana firm is developing a method to make oxygen on Mars for Nasa. Bacteria and algae will use Martian soil as fuel to pump out oxygen. Mars could be scattered with biodomes containing the organisms. And future astronauts could use this oxygen to survive on the surface (artist's illustration shown)

  • An Indiana firm is developing a method to make oxygen on Mars for Nasa
  • Bacteria and algae will use Martian soil as fuel to pump out oxygen
  • Mars could be scattered with biodomes containing the organisms
  • And future astronauts could use this oxygen to survive on the surface

If humans land on Mars in the 2030s as planned, one thing that will be essential to their survival will be self-sufficiency, as they won’t be able to take too much cargo with them.

With this in mind Nasa is testing whether oxygen can be created from Martian soil, without having to carry it all the way from Earth.

The innovative method would see bacteria or algae use the soil as fuel, pumping out usable oxygen in the process for astronauts on the surface.

Nasa has been working with Techshot Inc of Greenville, Indiana to develop this method in a so-called ‘Mars room’, which mimics the conditions on the red planet.
It is able to simulate the atmospheric pressure on the planet, in addition to the day-night temperature changes and the solar radiation that hits the surface.

In experiments, certain organisms were capable of producing oxygen from Martian soil - known as regolith - and they also removed nitrogen from it. 

‘This is a possible way to support a human mission to Mars, producing oxygen without having to send heavy gas canisters,’ said Eugene Boland, chief scientist at Techshot.

‘Let’s send microbes and let them do the heavy-lifting for us.’
The research is part of the Nasa Innovative Advanced Concepts (NIAC) Programme.

It’s envisioned that biodomes could be scattered across the surface to produce the oxygen needed for humans to survive.

The oxygen produced could also be stored for later use.

But while experiments on Earth are all well and good, the scientists want to test their method actually on Mars in the near future.

To do so, an upcoming rover - such as the 2020 Mars rover - could carry small container-like devices with Earth organisms inside.

The containers would be buried a few inches underground in certain locations, to see how successful they are at producing oxygen.

Sensors inside the container would detect how much oxygen was made, and report the findings back to a satellite in Mars orbit.

The scientists note that the container would be sealed tightly, to prevent the organisms being exposed to - and possibly contaminating - the Martian surface.

But if proven successful, future explorers on Mars may use multiple biodomes like this to produce the oxygen they need to survive.

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.

Astronomers Giddy Over What They Call A Cosmic ‘Dinosaur Egg’ About To Hatch



cosmic dinosaur egg
The Antennae galaxies, shown in visible light in a Hubble image (upper image), were studied with ALMA, revealing extensive clouds of molecular gas (center right image). One cloud (bottom image) is incredibly dense and massive, yet apparently star free, suggesting it is the first example of a prenatal globular cluster ever identified.


Excerpt from huffingtonpost.com

A dense cloud of gas 50 million light-years away has astronomers buzzing, and they're using all sorts of strange metaphors to get the rest of us to pay attention.

They've discovered what they think may be a globular cluster -- a big ball of up to one million stars -- on the verge of being born.

“This remarkable object looks like it was plucked straight out of the very early universe," Dr. Kelsey Johnson, an astronomer at the University of Virginia in Charlottesville and lead author on a paper about the research, said in a written statement. "To discover something that has all the characteristics of a globular cluster, yet has not begun making stars, is like finding a dinosaur egg that’s about to hatch.”

Johnson and her colleagues spotted the bizarre object, which they call the "Firecracker," using the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama desert in Chile. It's located inside a pair of interacting galaxies known to scientists as NGC 4038/NGC 4039, or The Antennae Galaxies.

The Firecracker has a mass that's 50 times that of our sun, and is under an enormous amount of pressure -- roughly 10,000 times greater than the average pressure in interstellar space. According to the researchers, this makes it a good candidate for collapsing into a globular cluster within the next million years.

What do other scientists make of the discovery? Dr. Alison Peck, ALMA scientist at the National Radio Astronomy Observatory, who was not involved in the new research, called it "important" and said she was "really excited to hear about these results."
She told The Huffington Post in an email:
"One of the things that we all yearn to understand is how our surroundings formed, how our galaxy and our solar system came to be. To do this, since we can’t actually watch things change over time, (it just takes too long), we need to find similar objects at different stages of development and compare them. What Dr. Johnson’s team have found here is an analog of an object that we look for in the very early universe, but they’ve found it so close by that we’ll be able to make extremely detailed observations and find out much more about the physical conditions in this exciting region."
The research is set to be published in the Astrophysical Journal.

What astronomers learned when Messenger space probe crashed into Mercury



Excerpt from statecolumn.com


On April 30, NASA concluded an historic voyage known as the Mercury Surface, Space Environment, Geochemistry and Ranging mission. The mission came to an end when the spacecraft carrying analytical instruments, Messenger, crashed into the planet’s surface after consuming all of its fuel.
The mission was far from a waste, however, as NASA rarely expects to see the majority of the spacecraft they launch ever again. According to Discovery, The probe sent back a spectacular photo of the surface of Mercury, using the craft’s Narrow Angle Camera in tandem with the Mercury Dual Imaging System. The photo shows a mile-wide view of the nearby planet’s surface in 2.1 meters per pixel resolution.
Right after the probe delivered the photo to NASA’s Deep Space Network, which is a collection of global radio antennae that tracks data on the agency’s robotic missions around the solar system, the signal was lost in what scientists assume was the craft’s final contact with the closest planet to the sun.
The four-year mission came to an end when the craft could no longer maintain its orbit around the solar system’s innermost planet due to lack of fuel. Mercury is just 36 miles from the sun, compared to Earth, which is 93 million miles away from the center of the solar system. Mercury is a peculiar world, with both frigid and extremely hot temperatures. Messenger also revealed that Mercury has a magnetic field similar to that of Earth’s, created by the motion of metallic fluids within the planet’s core.
The main challenge the Messenger mission faced was getting the space probe into orbit around Mercury. Due to the planet’s proximity to the sun, it was extremely difficult for flight engineers to avoid its gravitational pull. In addition to the challenge of catching Mercury’s comparatively weak gravitational force, high temperatures also made things tricky. Messenger was equipped with a sunshield designed to protect the spaceship cool on the side that faced the sun. NASA engineers also attempted to chart a long, elliptical orbit around Mercury, giving Messenger time to cool off as it rounded the backside of the planet.
Messenger made over 4,000 orbits around Mercury between 2011 and 2015, many more than the originally planned one-year mission would allow.
With the close-up shots of Mercury’s surface provided by Messenger, NASA scientists were able to detect trace signals of magnetic activity in Mercury’s crust. Using clues from the number of impact craters on the surface, scientists figured that Mercury’s magnetized regions could be as old as 3.7 billion years. Astronomers count the craters on a planet in order to estimate its age – the logic being that younger surfaces should have fewer impact sites than older surfaces.
The data sent back by Messenger has caused astronomers to reconsider their understanding of Mercury’s magnetic history. They now date the beginning of magnetism on Mercury to about 700 million years after the planet was formed. They cannot say for sure, however, if the magnetic field has been consistently active over this timeframe.
According to Messenger guest investigator Catherine Johnson, geophysicist at the University of British Columbia in Vancouver, that it was possible the magnetic field has been active under constant conditions, though she suspects it might also oscillate over time, like Earth’s. Information for the time period between 4 billion years ago and present day is sparse, though Johnson added that additional research is in the pipeline.
Johnson was pleased, however, with the insight offered into Mercury’s formation provided by these new magnetic clues. Magnetism on a planetary scale typically indicates a liquid metal interior. Since Mercury is so tiny, scientists originally believed that its center would be solid, due to the rate of cooling. The presence of liquid in the planet’s center suggests other materials’ presence, which would lower the freezing point. This suggests that a totally solid core would be unlikely.
Mercury’s magnetic field offers valuable insight into the formation of the planet, the solar system, and even the universe. Magnetism on Mercury indicates that it has a liquid iron core, according to Messenger lead scientist Sean Solomon of Columbia University.

Jane Goodall Says SeaWorld ‘Should Be Closed Down’

Jane Goodall


Excerpt from huffingtonpost.com

NEW YORK -- Jane Goodall wants to see SeaWorld go extinct.
The 81-year-old primatologist said whales and dolphins should never be held in captivity, and that the entertainment company known for its orca shows should be shuttered.

“They definitely should be closed down,” Goodall said in an interview with The Huffington Post earlier this month. 

She’s not alone. SeaWorld’s stock price has been plummeting since July 2013, when CNN released the documentary “Blackfish." The film exposed the misery endured by SeaWorld's trained orca and the dangers posed to trainers working with stressed-out carnivorous whales. 

seaworld stock
SeaWorld's stock price has declined precipitously since the 2013 release of "Blackfish."

One of the problems highlighted in "Blackfish" is that cetacea, the family of aquatic mammals that includes whales, dolphins and porpoises, communicate with sonar-like sound waves. When confined to tanks, Goodall noted, those waves echo back and create a hellish cacophony for the animals.

“When they are contained in these tanks … that is acoustical hell,” said Goodall, adding that her nonprofit organization, the Jane Goodall Institute, is urging aquariums across the country to free their whales. “The sounds bounce back from the walls of the tank.”

SeaWorld aggressively refuted many of the film's claims, including allegations that its whales were unhealthy and that the company tried to cover up details surrounding the 2010 death of trainer Dawn Brancheau, who was mauled by an orca. 

After the release of "Blackfish," SeaWorld saw a rapid decline in visitors, and with that, in the price of shares. But on Monday, Goldman Sachs upgraded the stock, optimistic that the company can retool its image as consumers start forgetting about the blockbuster documentary.

"Jane Goodall is a respected scientist and advocate for the world’s primates, but we couldn’t disagree more with her on this," Becca Bides, a SeaWorld spokeswoman, said in an emailed statement. 

"Zoos and marine mammal parks like SeaWorld allow people to experience animals in a way that is inspiring and educational."
Asked about the allegation that SeaWorld's tanks are detrimental to whales, Bides denied the claim, arguing that they are specially crafted to keep underwater noise levels quieter than the ambient ocean.

As of last December, SeaWorld held 22 orcas in its three U.S. marine parks, five of which were caught in the wild, according to the nonprofit advocacy group Whale and Dolphin Conservation. A total of 57 orcas are held in captivity around the world, the group notes. At least 160 orcas have died in captivity since 1961, and an additional 30 pregnant whales have miscarried or had stillborn calves.

Goodall said she remains hopeful that humans are gaining a greater sense of empathy for animals and losing interest in watching them perform for entertainment.

“It’s not only that they’re really big, highly intelligent and social animals so that the capture and confinement in itself is cruel,” she said of the captive orcas, but also that “they have emotions like ours.”
She welcomed the decision by Ringling Bros. and Barnum & Bailey Circus to eliminate elephants in its shows by 2018.

“If you see what happens to those baby elephants, the way they’re trained, it’s absolutely chilling,” said Goodall, who had a pendant in the shape of Africa hanging from her necklace. “They lose all of their young elephant playfulness, and then they can be trained.”

Lab for genetic modification of human embryos just $2,000 away – report


Reuters / Christian Charisius



Reuters

With the right expertise in molecular biology, one could start a basic laboratory to modify human embryos using a genome-editing computer technique all for a couple thousand dollars, according to a new report.

Genetic modification has received heightened scrutiny recently following last week’s announcement that Chinese researchers had, for the first time, successfully edited human embryos’ genomes. 
The team at Sun Yat-Sen University in Guangzhou, China, used CRISPR (clustered regularly interspaced palindromic repeats), a technique that relies on “cellular machinery” used by bacteria in defense against viruses. 

This machinery is copied and altered to create specific gene-editing complexes, which include the wonder enzyme Cas9. The enzyme works its way into the DNA and can be used to alter the molecule from the inside. The combination is attached to an RNA guide that takes the gene-editing complex to its target, telling Cas9 where to operate. 

Use of the CRISPR technique is not necessarily relegated to the likes of cash-flush university research operations, according to a report by Business Insider. 


Geneticist George Church, who runs a top CRISPR research program at the Harvard Medical School, said the technique could be employed with expert knowledge and about half of the money needed to pay for an average annual federal healthcare plan in 2014 -- not to mention access to human embryos. 

"You could conceivably set up a CRISPR lab for $2,000,” he said, according to Business Insider. 

Other top researchers have echoed this sentiment. 

"Any scientist with molecular biology skills and knowledge of how to work with [embryos] is going to be able to do this,” Jennifer Doudna, a biologist at the University of California, Berkeley, recently told MIT Tech Review, which reported that Doudna co-discovered how to edit genetic code using CRISPR in 2012. 

Last week, the Sun Yat-Sen University research team said it attempted to cure a gene defect that causes beta-thalassemia (a genetic blood disorder that could lead to severe anemia, poor growth, skeletal abnormalities and even death) by editing the germ line. For that purpose they used a gene-editing technique based on injecting non-viable embryos with a complex, which consists of a protective DNA element obtained from bacteria and a specific protein. 

"I suspect this week will go down as a pivotal moment in the history of medicine," wrote science journalist Carl Zimmer for National Geographic.


Response to the new research has been mixed. Some experts say the gene editing could help defeat genetic diseases even before birth. Others expressed concern. 

“At present, the potential safety and efficacy issues arising from the use of this technology must be thoroughly investigated and understood before any attempts at human engineering are sanctioned, if ever, for clinical testing,” a group of scientists, including some who had worked to develop CRISPR, warned in Science magazine. 

Meanwhile, the director of the US National Institutes for Health (NIH) said the agency would not fund such editing of human embryo genes. 

“Research using genomic editing technologies can and are being funded by NIH,” Francis Collins said Wednesday. “However, NIH will not fund any use of gene-editing technologies in human embryos. The concept of altering the human germline in embryos for clinical purposes ... has been viewed almost universally as a line that should not be crossed.”

Although the discovery of CRISPR sequences dates back to 1987 – when it was first used to cure bacteria of viruses – its successes in higher animals and humans were only achieved in 2012-13, when scientists achieved a revolution by combining the resulting treatment system with Cas9 for the first time. 


On April 17, the MIT’s Broad Institute announced that has been awarded the first-ever patent for working with the Crisp-Cas9 system. 

The institute’s director, Eric Lander, sees the combination as “an extraordinary, powerful tool. The ability to edit a genome makes it possible to discover the biological mechanisms underlying human biology.”

The system’s advantage over other methods is in that it can also target several genes at the same time, working its way through tens of thousands of so-called 'guide' RNA sequences that lead them to the weapon to its DNA targets. 

Meanwhile, last month in the UK, a healthy baby was born from an embryo screened for genetic diseases, using karyomapping, a breakthrough testing method that allows doctors to identify about 60 debilitating hereditary disorders.

IBM advances bring quantum computing closer to reality

Excerpt from computerworld.com
By Sharon Gaudin

IBM scientists say they have made two critical advances in an industrywide effort to build a practical quantum computer, shaving years off the time expected to have a working system.

"This is critical," said Jay Gambetta, IBM's manager of theory of quantum computing. "The field has got a lot more competitive. You could say the [quantum computing] race is just starting to begin… This is a small step on the journey but it's an important one."

Gambetta told Computerworld that IBM's scientists have created a square quantum bit circuit design, which could be scaled to much larger dimensions. This new two-dimensional design also helped the researchers figure out a way to detect and measure errors.
Quantum computing is a fragile process and can be easily thrown off by vibrations, light and temperature variations. Computer scientists doubt they'll ever get the error rate down to that in a classical computer.


Because of the complexity and sensitivity of quantum computing, scientists need to be able to detect errors, figure out where and why they're happening and prevent them from recurring.

IBM says its advancement takes the first step in that process.
"It tells us what errors are happening," Gambetta said. "As you make the square [circuit design] bigger, you'll get more information so you can see where the error was and you can correct for it. We're showing now that we have the ability to detect, and we're working toward the next step, which would allow you to see where and why the problem is happening so you can stop it from happening."

Quantum computing is widely thought to be the next great step in the field of computing, potentially surpassing classical supercomputers in large-scale, complex calculations. 

Quantum computing would be used to cull big data, searching for patterns. It's hoped that these computers will take on questions that would lead to finding cures for cancer or discovering distant planets – jobs that might take today's supercomputers hundreds of years to calculate.

IBM's announcement is significant in the worlds of both computing and physics, where quantum theory first found a foothold.

Quantum computing, still a rather mysterious technology, combines both computing and quantum mechanics, which is one of the most complex, and baffling, areas of physics. This branch of physics evolved out of an effort to explain things that traditional physics is unable to.

With quantum mechanics, something can be in two states at the same time. It can be simultaneously positive and negative, which isn't possible in the world as we commonly know it. 

For instance, each bit, also known as a qubit, in a quantum machine can be a one and a zero at the same time. When a qubit is built, it can't be predicted whether it will be a one or a zero. A qubit has the possibility of being positive in one calculation and negative in another. Each qubit changes based on its interaction with other qubits.

Because of all of these possibilities, quantum computers don't work like classical computers, which are linear in their calculations. A classical computer performs one step and then another. A quantum machine can calculate all of the possibilities at one time, dramatically speeding up the calculation.

However, that speed will be irrelevant if users can't be sure that the calculations are accurate.

That's where IBM's advances come into play.

"This is absolutely key," said Jim Tully, an analyst with Gartner. "You do the computation but then you need to read the results and know they're accurate. If you can't do that, it's kind of meaningless. Without being able to detect errors, they have no way of knowing if the calculations have any validity."

If scientists can first detect and then correct these errors, it's a major step in the right direction to building a working quantum computing system capable of doing enormous calculations. 

"Quantum computing is a hard concept for most to understand, but it holds great promise," said Dan Olds, an analyst with The Gabriel Consulting Group. "If we can tame it, it can compute certain problems orders of magnitude more quickly than existing computers. The more organizations that are working on unlocking the potential of quantum computing, the better. It means that we'll see something real that much sooner."
However, there's still debate over whether a quantum computer already exists.

A year ago, D-Wave Systems Inc. announced that it had built a quantum system, and that NASA, Google and Lockheed Martin had been testing them.

Many in the computer and physics communities doubt that D-Wave has built a real quantum computer. Vern Brownell, CEO of the company, avows that they have.

"I think that quantum computing shows promise, but it's going to be quite a while before we see systems for sale," said Olds.
IBM's Gambetta declined to speculate on whether D-Wave has built a quantum computing but said the industry is still years away from building a viable quantum system.

"Quantum computing could be potentially transformative, enabling us to solve problems that are impossible or impractical to solve today," said Arvind Krishna, senior vice president and director of IBM Research, in a statement.

IBM's research was published in Wednesday's issue of the journal Nature Communications.
