A Krishanu Saha, assistant professor, biomedical engineering and medical history and bioethics, University of Wisconsin-Madison:
Editing genes involves changing the sequence of letters in the DNA. Researchers like to edit genes so they can understand the function of them, particularly genes that relate to various types of disorders that physicians have seen in the clinic. We can use this information to generate new hypotheses of how genes influence diseases.
Historically, editing the genome has been difficult. Several editing technologies go into cells and essentially use “genetic scissors” to cut up the DNA. Once you introduce a cut into the genome, repair processes will try to repair that break. This repair often occurs in imprecise ways that could potentially cause errors and mutations.
Instead, you could take advantage of those repair processes to have the genome incorporate a foreign piece of DNA that has the letters that you want to be inserted.
Such editing has been done in human cells for the last 15-20 years using a set of proteins called nucleases. Nucleases are engineered proteins that cut DNA.

Recently, the Cas9 nuclease, part of the CRISPR system, has really accelerated the pace of editing throughout biology and engineering.
To give you a frame of reference, about 10 years ago it cost about $50,000 to make only one precise cut in the genome. Attaining high precision was challenging: essentially finding a needle in a haystack, meaning editing one stretch of letters among 3 billion letters in the human genome. Understandably that was hard, and it took a lot of work to engineer the nucleases.
In the years since then, with the advent of the CRISPR system, a component called a guide RNA is used to attain precise editing. It’s easy to make the guide RNA, and this enables us to easily go after multiple parts of the genome at once. These components can be made very quickly on the order of a few dollars rather than thousands of dollars, making the technology more accessible for research.

(CNN)A new US government report delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars — or, in the worst-case scenario, more than 10% of its GDP — by the end of the century.
The federally mandated study was supposed to come out in December but was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping.
David Easterling, director of the Technical Support Unit at the NOAA National Centers for Environmental Information, emphasized that there was “no external interference in the report’s development.” He added that the climate change the Earth is experiencing is unlike any other.
“The global average temperature is much higher and is rising more rapidly than anything modern civilization has experienced, and this warming trend can only be explained by human activities,” Easterling said.
It’s the second of two volumes. The first, released in November 2017, concluded that there is “no convincing alternative explanation” for the changing climate other than “human activities, especially emissions of greenhouse gases.”
But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it’s demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history. Even if the best-case scenario were to happen and greenhouse gas emissions were to drop to nothing, the world is on track to warm 1.1 degrees Fahrenheit.
Without significant reductions in greenhouse emissions, the annual average global temperature could increase 9 degrees Fahrenheit (5 Celsius) or more by the end of this century, compared with preindustrial temperatures, the report says.
The costs of climate change could reach hundreds of billions of dollars annually, according to the report. The Southeast alone will probably lose over a half a billion labor hours by 2100 due to extreme heat.
Farmers will face extremely tough times. The quality and quantity of their crops will decline across the country due to higher temperatures, drought and flooding. In parts of the Midwest, farms will be able to produce less than 75% of the corn they produce today, and the southern part of the region could lose more than 25% of its soybean yield.
Heat stress could cause average dairy production to fall between 0.60% and 1.35% over the next 12 years — having already cost the industry $1.2 billion from heat stress in 2010.
When it comes to shellfish there will be a $230 million loss by the end of the century due to ocean acidification, which is already killing off shellfish and corals.Red tides,or algae bloom that deplete oxygen in the water and can kill sea life — like those that triggered a state of emergency in Florida in August — will become more frequent.
Impacts on our health
Higher temperatures will also kill more people, the report says. The Midwest alone, which is predicted to have the largest increase in extreme temperature, will see an additional 2,000 premature deaths per year by 2090.
There will be more mosquito- and tick borne diseases like Zika, dengue and chikungunya.West Nile cases are expected to more than double by 2050 due to increasing temperatures.
No one’s health is immune from climate change, the report concludes. People will be exposed to more foodborne and waterborne diseases.Particularly vulnerable to higher temperatures in the summer, children, the elderly, the poor and communities of color will be at a much greater risk for illness and death.
Heat and flooding
Wildfire seasons — already longer and more destructive than before — could burn up to six times more forest area annually by 2050 in parts of the United States. Burned areas in Southwestern California alone could double by 2050.
Dependable and safe water for the Hawaii, the Caribbean and others are threatened by these rising temperatures.
Along the US coasts, public infrastructure and $1 trillion in national wealth held in real estate are threatened by rising sea levels, flooding and storm surges.
Energy systems will be taxed, meaning more blackouts and power failures, and the potential loss in some sectors could reach hundreds of billions of dollars per year by the end of the century, the report said.
The number of days over 100 degrees Fahrenheit will multiply; Chicago, where these days are rare, could start to resemble Phoenix or Las Vegas, with up to two months worth of these scorching-hot days.
Sea levels have already gone up 7 to 8 inches since 1900. Almost half that rise has been since 1993, a rate of rise greater than during any century in the past 2,800 years. Some countries are already seeing land underwater.
By midcentury, it’s likely that the Arctic will lose all sea ice in late summer, and that could lead to more permafrost thaw, according to the report. As the permafrost thaws, more carbon dioxide and methane would be released, amplifying human-induced warming, “possibly significantly.”
What can be done
The report was created to inform policy-makers and makes no specific recommendations on how to remedy the problem. However, it suggests that if the United States immediately reduced its fossil fuel use and greenhouse gas emissions, it could save thousands of lives and generate billions of dollars in benefits for the country.
The Defense Department is trying to understand what risk climate change poses to security.But the Trump administration has signaled that the country will pull out of international initiatives like the Paris climate accord, aimed at lowering global temperatures, claiming that these treaties have been unfair for the US economy.
A report from the UN in October urged all governments to take “rapid, far-reaching and unprecedented changes in all aspects of society” to avoid disaster from climate change. That report predicted that the Earth will reach the crucial threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels by as early as 2030. It also suggested the world faces a risk of extreme drought, wildfires, floods and food shortages for hundreds of millions of people.
Time for action
Reactions to the new report have been strong across the scientific community.
“If we’re going to run this country like a business, it’s time to address climate as the threat multiplier we know it is before more lives are lost,” said Robert Bullard, an environmental scientist at Texas Southern University.
“In Houston, communities of color have endured back to back major weather events without the acknowledgment from Washington that climate change is the cause. We’ve known for years that it’s true and it’s important to our organizing and our local policy efforts that information like this is not only considered, but believed and acted upon.”
Scientists who have been raising the alarm about the negative consequences of climate change for years welcomed the findings.
“The findings in the Trump administration’s NCA report show how the health and daily lives of Americans are becoming more and more interrupted because of climate change,” said Beverly Wright, founding director of the Deep South Center for Environmental Justice and a professor at Dillard University. “We challenge the administration to finally begin using this information to rebuild and strengthen the communities in the direct path of the atrocities wrought by the fossil fuel industry and decades of poor policies that have neglected our concerns. The science is undeniable, let’s fix it.”
CNN’s Brandon Miller, Gregory Wallace, Kevin Flower and Rene Marsh contributed to this report.

DON’T JUST TAKE OUR WORD FOR IT, READ WHAT A MASTER BREEDER HAS TO SAY ABOUT SPECTRUM KING LED
Article by Mr. Spliff of Cannabis
I have well over a decade of growing the absolute finest cannabis.
I personally consume a lot of cannabis as well. I know cannabis very well. I know the industry and its struggles very well. Cannabis is my life. I have used every kind of plant food, grown in every kind of medium, run every size or room, tried every trade secret and use every available form of lighting technology.
There are so many critical variables when operating a successful garden. As that garden becomes the centerpiece of a growing business it is extremely important to control these variables. Some variables outweigh others, but it is a perfectly functioning system we wish to achieve.
In my experience the most critical variable is lighting. Everything in gardening is about maximizing photosynthesis. environment, plant food, medium and so many other like variables are designed to maximize photosynthesis. As this is the case it is imperative to have a lighting program that really drives the plants to their full potential.
I have used many different forms of indoor lighting. Metal Halide and HPS HID lighting, both single ended lamps and double ended lamps. CHM/LEC 315w lamps in various reflector setups. Many forms of fluorescent and induction lighting. I have used many different builds of LED lighting as well. Companies make claims left and right about better power usage or cooler operating temps or cheaper initial costs and sometimes even government rebates/reimbursement… at the end of the day it comes down to 1 thing and 1 thing alone. Performance.
The SPECTRUM KING Low Pro Veg LED is hands down the most effective and high-performance lighting system I have ever used. It is the way the plants react to the spectrum. Their increased rate of growth and structure of that growth. The way the light drives the plants to build a massive and dense root system. Absolutely perfect and luscious plant tissue. Huge stalks and stems that developed quickly.
Most modern lighting systems are no bigger than a shoe box. This creates a centralized source of light that leaves a lot to be desired when lighting larger spaces of plants. This can lead to non-uniform structure in the plants. The SPECTRUM KING Low Pro Veg is a 4’ x 4’ lighting deck that is so powerful, so consistent and uniform in its broadcast of light. This translates directly to the uniformity and consistency of the plants. I have never seen a lighting system that delivers like Low Pro Veg. I have seen at least a 20% increased growth rate, better plant structure and stronger plant presence with the Low Pro Veg than any other lighting system. The Low Pro Veg being a dimmable unit allows vegetative plants to stay in the same space for the term of their cycle as you can dim the output as the plants get closer to the lighting unit keeping them from light toxicity and fouled plant tissue and form. These lighting fixtures also require little to no environmental control to maintain ideal temperatures in the grow space. The SPECTRUM KING Low Pro Veg LED has so many advantages. Truly professional grade lighting for the modern indoor Commercial/Recreational/Medical cultivator!
Product shot of the SPECTRUM KING Low Pro Veg LED
If a garden is the business and LIGHT drives the garden then it is of the highest importance that your lighting equipment is powerful and consistent. In this ever-growing industry the only businesses that will survive is those with a consistent result and powerful presence. The SPECTRUM KING Low Pro Veg LED is the only light I recommend for vegetative cycle lighting.
It should be noted that I have observed 100+ strains/varieties under the Low Pro Veg. Exceptional results across the board.

This image of a dusty, gas-rich nebula looks pretty, but appearances can be deceiving. Known as a Wolf-Rayet star system, it’s poised to unleash a catastrophic gamma-ray burst when it finally goes supernova. What’s remarkable about this particular Wolf-Rayet system, however, is that it’s the first to be discovered in our own galaxy. Cue the ominous music…
This Wolf-Rayet star system is formally known as 2XMM J160050.7-514245, but to the researchers who recently investigated this enigmatic object, it’s simply “Apep”—an exotic object named for the serpentine ancient Egyptian god of chaos. In a press release, Joseph Callingham, the lead author of the new study and an astronomer at the Netherlands Institute for Radio Astronomy (ASTRON), said “it’s the first such system to be discovered in our own galaxy”—a system he never expected to find “in our own backyard.” The details of this research were published today in Nature Astronomy.
Indeed, astronomers have observed Wolf-Rayet stars before, but only in other galaxies. These massive star systems are on the verge of entering into their death throes, at which time they’ll generate a type of supernova that emits an extremely powerful and narrow jet of plasma—the dreaded gamma-ray burst.
Apep is one such gamma-ray progenitor system, featuring a massive triple star system at its core—a binary pair and a lone star—and vast spiral arms composed of gas and dust. The system is located around 8,000 light-years from Earth, which is uncomfortably close given its explosive potential.
“This was a very fun project to do in some ways, in the sense that Joe found this object and first showed it to me in 2012 when we were officemates as undergrads in Sydney—and it took us six years to gather all the data to reveal this surprising story,” Benjamin Pope, a NASA Sagan fellow at New York University’s Center for Cosmology and Particle Physics and a co-author of the new study, told Gizmodo. “Sometimes science is slow! But I remember when last year, the day before my PhD defense in Oxford, he was visiting and showed me the picture of the Apep spiral—I literally gasped, it was so shocking. There’s really nothing quite like this.”
Using the VISIR mid-infrared camera on the European Southern Observatory’s Very Large Telescope, Pope, Callingham, and their colleagues measured the velocity of the dust within the spiral arms. At this end-stage of their brief life cycle (these systems only last a few hundred thousand years—a blink of the eye in cosmological terms), stars within Wolf-Rayet systems spin rapidly, producing stellar winds that move at horrendous speeds. These winds carry significant portions of stellar material into space, and they’re responsible for forming the majestic plumes of dust particles. In the case of Apep, its spiral arms measure several light-years across.
By measuring the rotational speeds within this nebula, the researchers concluded that at least one of the three stars within the system is spinning fast enough such that it’ll trigger a long-duration gamma-ray burst when it finally explodes as supernova (the exact timing is still impossible to predict). The speed of gas within the nebula was clocked at 12 million kilometers per hour, but the dust is moving at “just” 570 million kilometers per hour. The researchers say this discrepancy is indicative of a star approaching near-critical rotation.
“Apep’s dust pinwheel moves much slower than the wind in the system,” said Callingham. “One way this can occur is if one of the massive stars is rotating so quickly that it is nearly tearing itself apart. Such a rotation means that when it runs out of fuel and begins to explode as a supernova, it will collapse at the poles before the equator, producing a gamma-ray burst.”
The significance of this finding, said Pope, is that nobody had observed rapidly rotating Wolf-Rayet systems in our galaxy before. Moreover, many astronomers assumed these objects couldn’t even exist in a galaxy like ours; the Milky Way is old and metal-rich, containing an abundance of heavy stars that should spin down quickly. The new result suggests our understanding of how massive stars die is still incomplete.
“Wolf-Rayet star systems are thought to be the progenitors of long gamma-ray bursts, so if there’s one in our galaxy that’s an exciting find,” Pope told Gizmodo. “Even if not—something deeply weird is happening to this star system and this is the best explanation we have.”
As noted, gamma-ray bursts are among the most powerful explosions known to astronomers. Lasting from between two seconds and a few hours, long-duration gamma-ray bursts release as much energy as the Sun does over the course of its entire lifetime. Disturbingly, some scientists theorize that the Ordovician-Silurian extinction—a mass extinction event that happened on Earth some 440 million years ago—was caused by a gamma-ray burst within our own galaxy. Physicist Adrian Melott from the University of Kansas speculates that a “dangerously near GRB should occur on average two or more times per billion years.”
Pope said it would be “pretty bad” if one were to go off nearby, but he’s not particularly concerned.
“In terms of why we have nothing to worry about, the best I can offer is that it’s highly uncertain whether Apep will go off as a gamma-ray burst at all, and if it does, it is unlikely to be in the very near future.”
As another point of encouragement, gamma-ray bursters are highly directional, spewing their concentrated, high-energy rays in a specific direction. So for Apep to pose a threat, it would not only have to go supernova, it would also have to be pointed in our general direction.
Regardless, there’s nothing we can really do about it except to learn more about Wolf-Rayet systems. It might also be useful to speak the ancient Egyptian incantation to rid the world of Apep’s destructive powers:
Spitting upon Apep, Defiling Apep with the left foot, Taking a lance to smite Apep,Fettering Apep, Taking a knife to smite Apep, Putting fire upon Apep…

JERUSALEM (AP) — More than a decade before the Nazis seized power in Germany, Albert Einstein was on the run and already fearful for his country’s future, according to a newly revealed handwritten letter.
His longtime friend and fellow Jew, German Foreign Minister Walther Rathenau, had just been assassinated by right-wing extremists and police had warned the noted physicist that his life could be in danger too.
So Einstein fled Berlin and went into hiding in northern Germany. It was during this hiatus that he penned a handwritten letter to his beloved younger sister, Maja, warning of the dangers of growing nationalism and anti-Semitism years before the Nazis ultimately rose to power, forcing Einstein to flee his native Germany for good.
“Out here, nobody knows where I am, and I’m believed to be missing,” he wrote in August 1922. “Here are brewing economically and politically dark times, so I’m happy to be able to get away from everything.”
The previously unknown letter, brought forward by an anonymous collector, is set to go on auction next week in Jerusalem with an opening asking price of $12,000.
As the most influential scientist of the 20th century, Einstein’s life and writings have been thoroughly researched. The Hebrew University in Jerusalem, of which Einstein was a founder, houses the world’s largest collection of Einstein material. Together with the California Institute of Technology it runs the Einstein Papers Project. Individual auctions of his personal letters have brought in substantial sums in recent years.

The 1922 letter shows he was concerned about Germany’s future a full year before the Nazis even attempted their first coup — the failed Munich Beer Hall Putsch to seize power in Bavaria.
“This letter reveals to us the thoughts that were running through Einstein’s mind and heart at a very preliminary stage of Nazi terror,” said Meron Eren, co-owner of the Kedem Auction House in Jerusalem, which obtained the letter and offered The Associated Press a glimpse before the public sale. “The relationship between Albert and Maja was very special and close, which adds another dimension to Einstein the man and greater authenticity to his writings.”
The letter, which bears no return address, is presumed to have been written while he was staying in the port city of Kiel before embarking on a lengthy speaking tour across Asia.
“I’m doing pretty well, despite all the anti-Semites among the German colleagues. I’m very reclusive here, without noise and without unpleasant feelings, and am earning my money mainly independent of the state, so that I’m really a free man,” he wrote. “You see, I am about to become some kind of itinerant preacher. That is, firstly, pleasant and, secondly, necessary.”
Addressing his sister’s concerns, Einstein writes: “Don’t worry about me, I myself don’t worry either, even if it’s not quite kosher, people are very upset. In Italy, it seems to be at least as bad.”
Later in 1922, Einstein was awarded the Nobel Prize in physics.

Ze’ev Rosenkrantz, the assistant director of the Einstein Papers Project at Caltech, said the letter wasn’t the first time Einstein warned about German anti-Semitism, but it captured his state of mind at this important junction after Rathenau’s killing and the “internal exile” he imposed on himself shortly after it.
“Einstein’s initial reaction was one of panic and a desire to leave Germany for good. Within a week, he had changed his mind,” he said. “The letter reveals a mindset rather typical of Einstein in which he claims to be impervious to external pressures. One reason may be to assuage his sister’s concerns. Another is that he didn’t like to admit that he was stressed about external factors.”
When the Nazis came to power and began enacting legislation against Jews, they also aimed to purge Jewish scientists. The Nazis dismissed Einstein’s groundbreaking work, including his Law of Relativity, as “Jewish Physics.”
Einstein renounced his German citizenship in 1933 after Hitler became chancellor. The physicist settled in the United States, where he would remain until his death in 1955.
Einstein declined an invitation to serve as the first president of the newly established state of Israel but left behind his literary estate and personal papers to the Hebrew University.

A new discovery is strengthening the idea that a large, mysterious planet — known as Planet 9 or Planet X — may be lurking unseen at the Solar System’s edge. Astronomers say they have found a tiny object orbiting far out from the Sun that fits with the Planet X theory. In fact, the object may have even been pushed onto the path it takes now by this hidden planet’s gravity.
The tiny rock — eloquently named TG387 and nicknamed “The Goblin” — was spotted by astronomers at the Carnegie Institution of Science using a giant Japanese observatory in Hawaii called Subaru. The Carnegie team first spotted the object in 2015 and then followed it on its journey around the Sun for the last four years. Those observations revealed an incredibly distant target. TG387 takes a whopping 40,000 years to complete just one orbit around the Sun. And it’s on a very elliptical path far from the inner Solar System; the closest it ever gets to the Sun is 65 Astronomical Units (AU), or 65 times the distance between the Sun and the Earth. For reference, Pluto only gets as far as 49 AU’s from the Sun.
This orbit is particularly enticing since it puts TG387 in a select group of distant Solar System objects that all point to the possible existence of Planet X. Right now, there are 14 far-out space rocks that all share similar orbit patterns, suggesting that this planet is out there. Their paths are all super elongated, and they all cluster together in the same area when they approach the Sun. Plus, their orbits are all tilted alike, and they point in the same general direction, as if something big has pushed them into similar places. These objects are the strongest lines of evidence astronomers have for Planet X, and finding a new one that matches this pattern reinforces that idea that this planet is more than just a theory.
Plus, each new find helps astronomers narrow down where to look for Planet X. “Each time we find another one of these smaller objects, it will lead us to constrain where the bigger planet could be,” Scott Sheppard, an astronomer at Carnegie Science and the lead author of a study in The Astronomical Journal detailing the discovery, tells The Verge. “They’re all on very similar orbits, but their orbits are all slightly different, which [limits] where the planet could be.”
The idea that a giant planet is lurking beyond Neptune is an idea that astronomers have speculated for the last century. However, the hunt for this planet turned much more serious in 2012, when Sheppard and his team found a far-flung object that was truly unique. It was an object called VP113, and it currently holds the record for the most distant object orbiting the Sun. The closest it ever gets to the star is 80 AU’s, or 80 times the Earth-Sun distance. Sheppard noticed that this object also followed a path similar to those of a few other distant space rocks, as well as a far-off dwarf planet called Sedna. “They all have this clustering, and so that suggested that something was pushing them into similar types of orbits,” says Sheppard.
Then, in 2016, a pair of researchers from Cal Tech, Mike Brown and Konstantin Batygin, did the math. Based on the orbits of six of these objects, they estimated that there’s a planet roughly 10 times the mass of Earth orbiting far beyond Neptune. Their calculations showed that it possibly takes 10,000 to 20,000 years to orbit the Sun. Brown and Batygin dubbed the phantom planet “Planet 9,” though others had been calling it Planet X years before.
Since then, more and more objects have been found that fit this orbit pattern. The idea is that these objects are in just the right orbits needed to survive Planet X’s gravitational wrath. If they followed any other path, they would likely collide with the big planet or the planet’s gravity would send them hurtling out of the Solar System. However, all of these very distant extreme objects orbit in such a way that they never get close to Planet X when it crosses their orbits. “Whenever the planet is crossing the orbit of one of these objects, these objects are on the other side of the Solar System. So they never get close to each other,” says Sheppard.
But not all of these objects are as reliable narrators as they could be. “Among these 14 objects, some tell a more precise story than others,” Batygin, who was not involved with today’s study, tells The Verge. For one thing, some of the objects cross the orbit of Neptune, and that planet’s gravity might have some influence on the objects and warp their routes. “Neptune has the effect of muddying things up, even if you have an orbit carefully sculpted by Planet 9.” That makes it hard to know whether or not the object is truly pushed about by this unseen planet.
But this new discovery, TG387, is special because its orbit is so distant. When it’s farthest from the Sun, the rock will be at an extreme 2,300 AU’s away. In fact, it’s remarkable that astronomers found it all since it’s about seven times smaller than Pluto and so far off. But because of its extreme distance, TG387 is not influenced in any way by the large objects in the inner Solar System. Jupiter, Saturn, Uranus, and Neptune don’t have any effect on its orbit. That means if this object was truly batted around by Planet X, it might hold more information about the planet’s orbit than other objects do. And when the team ran simulations of the Solar System with a Planet X in it, they found that this object’s orbit isn’t subject to change. “This one joins an elite group of six objects that are stable,” says Batygin.
Of course, Planet X is nowhere near a done deal. There are only 14 objects that potentially support its existence. That’s a super low number by statistical standards. “We don’t have tens of these objects,” Michele Bannister, an astronomer studying distant small bodies at Queen’s University Belfast, who was not involved with this research, tells The Verge. “I’d be very happy if we had tens, but there’s barely even a handful.” Additionally, Bannister says it’s important to remember that astronomers still don’t have a comprehensive snapshot of the distant Solar System. The time of year, the weather, and the part of the sky a telescope observes all influence the kind of objects that are discovered out there, adding bias to the sample.
Plus, the objects that we find are typically on their closest approaches to the Sun on their super distant orbits, and that skews our discoveries a bit. For instance, TG387 was found when it was around 80 AU’s away, not thousands of AU’s away. That means we may not have a good idea of what all is out there because we can’t see the objects that are super far out on their orbits. “Each of these objects we detect is the tip of an iceberg for a larger population,” says Bannister. For every new discovery made, there must be hundreds of thousands of more objects that astronomers can’t see. And those objects could tell a different story than the Planet X one.
However, Bannister, who predicted that an object like TG387 could exist in the Solar System, does say this discovery is instrumental in helping to shape our understanding of the distant Solar System. We still don’t understand why there are objects like this one that are completely detached from the rest of the planets. “They’ve made a great discovery,” she says. “These are exactly the objects we need to be finding to understand the formation and history of our Solar System.”
Meanwhile, our best hope in the search for Planet X is to find more objects that corroborate its existence. “We don’t expect every object we find to fit this pattern, though that is what is happening right now,” says Sheppard. Better yet, finding Planet X would be pretty convincing, too. The problem is that there’s a lot of sky to scour and our telescopes don’t cover that much area at a time. The Subaru telescope in Hawaii is perhaps the best tool since it can observe the area of about six full Moons at a time. But it’s still tough to pinpoint the exact location of such a faraway, faint planet. “It’s a lot like looking for your target with a sniper rifle,” says Batygin. “You have to know where to look.”
But TG387 does help point astronomers in a slightly better direction. Before this discovery, there were about 30 orbits that Sheppard and his team thought Planet X could be on. Now, there are only 25 or so, he says. And the astronomers will be back at Subaru in mid-October to pick up the search. “We’ve covered about 30 percent of the prime area, and we hope by the end of this year, we’ll have covered 60 to 70 percent of that prime area,” says Sheppard.
If Planet X is found, then a whole new crop of questions will arise. Perhaps the biggest one of all is where did it come from? Most don’t think it’s possible for this planet to have formed where it is now. It likely formed in the inner Solar System and got flung outward, perhaps by Jupiter or Saturn. “That would suggest a lot of big things formed in our Solar System, and it was a very chaotic place in the formation era,” says Sheppard.
But before those questions can be answered, Planet X must be found. And those on the hunt are sure it will happen. “I’m really quite confident — about a 99 percent level of confidence — that Planet 9 is really out there,” says Batygin. “It might take on the order of a decade to find, but I’m quite confident it’s there.”

Creationism AND Evolution: There Is Truth In Both Of Them
I am a devout life long Christian yet I have for most of my adult life debated how Christians (for the most part) are so oblivious to reality and to the Truths that are shown us in the Bible. So many people who believe in the Bible as the Holy Spirit Inspired Word Of God (as I also do) tend to read the Bible with ‘Church Doctrine’ blinders on. Back in the time of the Apostles and the time that Jesus walked the Earth when they taught in the Synagogues the people studied the Scriptures to see if what they were being taught was the truth or not. Just because your Preacher or a Church Elder, Bishop, or if you are Catholic, even the Pope, tells you something it is your Christian obligation to search out the Scriptures to see if what you are being told is Biblical truth.
Reality is that the ignorance of Christians/Churches have convinced millions if not billions of people throughout history to turn their backs on the Jewish and the Christian faith. Right from the very first book of the Bible (Genesis) Christians and Jews do not understand what we are so plainly being told. Yes the world and all in it were created in six days, but those six days are not, were not, human days, they were God’s days. I nor any other human knows what one of God’s days represent compared to a human day but Scripture tells us over and over again that God’s days are not our days yet humans keep trying to make that be so anyway. Even in our own solar system every single planet that circles the sun has a different amount of our hours in one of their days. Some will, through their ego’s say, well why didn’t Moses just lay it all our for us so we could know exactly everything? Folks, almost all of the humans that were alive about 3,600-3,700 human years ago calculated time through their own ancestors which normally only traversed back 3, 4, or 5 generations at best. Do you honestly think if Moses had started teaching them of thinks that happened 3 or 4 billion years ago that these people would have listened to him? What if Moses had started laying out the lineage of Dinosaurs, what do you think they would have done? My guess is that the people would have shunned him for being a crazy man.
Most all of us know some about the story of Adam and Eve from the first two chapters of Genesis but my question to everyone is, just how well have you read it? Have you just taken the word of the Church you attend as to what the Scripture actually is telling us all? Please reread the first two chapters. If you will notice in the first chapter Adam was created but before His creation God created ‘men and women, and, God created He them’. After God had created multiple ‘men and women’ God created Adam. Now in the first chapter, after God did all of His creating of those ‘Six Days’, God rested from His work on the 7th day. Then after all His work was done and He had created the first group of people (the Gentiles) and Adam, then in chapter #2 God then created Eve to be a help mate for Adam. Folks, the ‘promised one, the Messiah, Jesus The Christ’ lineage is traced back through the ‘Royal Blood Line’ to Adam, actually to Eve. There were two human creations, the gentiles, and the Royal Blood Line of Adam. Adam and Eve were about 5,500 human years ago yet humans were on this planet many thousands of years before this time. Jesus Himself referred to us Gentiles as “people before this time whom were not a people”. Jesus was pointing out that before His time here on Earth, before His Resurrection that salvation was only to the Jews and to no one else. So, people who were not a people, Gentiles! These are simple truths laid out in writing for us all to see yet we choose to remain blind. Think about a few things we are told here in the beginning of Genesis. After Cain had murdered his brother Able God banished Cain to the East of Eden in the land of Nod. God put a mark on the forehead of Cain so that “all who find him would not kill him”, folks, all of who? There were only 3 people left on the planet right, just Cain, his Mom Eve and his Dad Adam, so all of whom? Then after Cain had been banished he took a wife, wait a minute, where did she come from? Moses wrote the first five books of the Bible/Torah through the guidance of God’s Spirit, whom we tend to call the Holy Spirit from the New Testament. The Truth of the Scriptures are right before our eyes, but we have been trained not to see the real Truth. We have been taught Church doctrines instead which has run many millions of people away from God’s teachings.
If Moses had told the people of his time that the world was about 4-5 billion years old and that the planet we call Earth had started with a big interstellar bang what do you think the people would have done to him? At the very least they would have thought him to be crazy and no one would have paid him any mind. To my Christian and Jewish brothers, yes there were such things as dinosaurs and there has been life on this planet for several hundred millions of human years. I did not say that there has been human life here on Earth for hundreds of millions of our years, just life itself. God does not want us to be ignorant for ignorance begets death, physical and spiritual. Science has pretty much discovered/proven that human life has been on this planet for hundreds of thousands of years, not just the 5,000-5,500 years since Adam and Eve. I am not an archaeologist even though I am a huge fan of history. I know that science has been looking for the so-called ‘missing link’ between Primates and Humans for longer than I have been alive. This is like trying to find that pot of gold at the end of a rainbow, it doesn’t exist folks.
Evolution, is there such a thing? Of course there is folks. As an example I would like to use the people science calls Neanderthals. For most of my life time scientist have wondered what happened to them, why did they go extinct? Just like the people before them who bred with them the same thing happened to them, they were bred out of existence. You can breed cattle with buffalo and you get what is called beefalo. You can take oranges and breed them with tangerines and you get a product called tangelos. In Scripture the ‘House of Israel’ was forbidden to mix blood with any of the Gentiles, if they did then they were counted as not being pure. Humans did not crawl up out of the oceans and even though we have many of the same molecules of other creatures we did not derive from them and they did not derive from us. Today science can create a form of a human being through cloning and some would call this evolution, that we have evolved into a more pure condition but they are ignorant of reality. Science can play God, but they are not God. Just as if I could make an android and give it a human name like George, George is still not a human. The difference in these two creations of science and a real human being is that science can not create ‘a Soul’. It is the Soul that makes the conscientiousness that makes one human and only God can create the Soul. Is there such a thing as evolution, of course there is, just not to the extent that some scientist believe and or are trying to find or create.
Science has some things wrong, yet they do have many things correct. Churches have many things correct, yet they have many things wrong. It is the job of the Churches to teach the whole Truth but first the Churches must open their eyes to what the Scriptures actually say and to forget about ‘Church doctrines’. The Earth is a special place for it is designated to be “God’s Footstool”. Earth is where Jesus will reign from once the New Jerusalem comes down from Heaven to replace the current city of Jerusalem once it has been totally destroyed after the Second Advent. Now, Christians, wake up to reality about other planets. Do you honestly think that if God is the Creator of all things in the Heavens and on the Earth that He created billions of planets for no purpose or reason at all? To the best of my knowledge I have never seen an alien yet I totally believe that they exist, it would be difficult to honestly believe other wise. Then again there is the issue of, what does an alien actually look like? Personally I have no idea, but I do doubt that they look like humans. Personally I believe in the existence of Angels, I also believe that I have seen and spoken with at least two in my lifetime. I also believe in the existence of Satan and of His Angels, to me, to not believe in both is Biblical ignorance. I personally do not know if I have ever spoken directly with any Demons but I think that there is a very good chance that I have several times. I know that I have experienced being in places and in the presence of a few people where the feeling of pure evil was like a stench in the air, you could feel it, you could almost taste it. Remember, if you spend your life trying to be good and trying your best to be the best follower of Christ that you know how to be, you make yourself a target for the hate of evil ones, humans and otherwise.

“In two years, China will be ahead of the United States in AI (artificial intelligence),” states Denis Barrier, CEO of global venture firm Cathay Innovation. Others say the same. If so, China will largely determine how this technology transforms the world. Today’s contest is more than a race for dominance in a new technology — it’s one between authoritarianism and democracy.
“AI is the world’s next big inflection point,” says Ajeet Singh, CEO of Thought Spot in Palo Alto. Artificial intelligence is machine learning, which self-learns programmed tasks, using data, and the more it gets, the more learned it becomes. It drives cars, recognizes individuals, diagnoses diseases and more. Like past informational technologies, artificial intelligence will convey advantages to the nation that leads its use — accelerating research, increasing productivity and enabling dominant military capabilities.
Hence, China’s race to dominate the technology.
In the United States, companies and agencies are pursuing artificial intelligence development in a decentralized manner. In China, the government has a focused national effort, following Google’s Deep Mind artificial intelligence defeating the world’s top Go players in 2016-17. That defeat was China’s “Sputnik moment,” (the moment that a technological achievement by a rival galvanized American political resolve to invest in space technology) — one the U.S. has yet to have with artificial intelligence. And, unlike the United States, China has a national strategy for artificial intelligence, setting milestones, accelerating China’s pursuit of the technology: 2020: Be equal to the United States 2025: Surpass the United States 2030: Lead the world as an artificial-intelligence innovation center
“Research institutes, universities, private companies and the government all working together … I haven’t seen anything like it,” said Steven White, an associate professor at Tsinghua University, China’s MIT. In the race for artificial intelligence dominance, “the U.S. will lose because they don’t have the resources,” said White.
But, needs are driving China, too. It’s artificial intelligence strategy addresses: Its shrinking labor force — A “national crisis,” says the National Committee of Chinese People’s Political Consultative Conference, which predicts China’s working population will drop from 631 million in 2020, to 523 million in 2035, and 424 million in 2050. China must also care for a growing elderly population. The United Nations estimates China’s over-65-age group will increase from about 160 million in 2020, to 360 million in 2050. How to remain an economic power — China seeks to operate almost a million robots and produce 150,000 industrial ones in 2020.
Growing health care needs — China seeks a “rapid, accurate intelligent medical system,” including artificial intelligence-scanning imagery for cancer, robots providing medical references for doctors, and artificial intelligence-powered online consultations. Military dominance of the East and South China seas, which allows access for China’s export-driven economy. China’s government seeks a civil-military fusion of artificial intelligence, enabling faster military decision-making, robotic submarines and large drone swarms that could overwhelm opposing forces. Control by the Communist Party over China’s population. Internal unrest — coastal rich vs. interior poor; ethnically different regions like Tibet; an anxious middle class; and pro-democracy efforts — has long concerned authorities. China is using artificial intelligence to build an Orwellian state. Smart cities track peoples’ movements. China, netted with millions of cameras and facial and vehicle recognition systems, can rapidly identify individuals. Police wear facial recognition glasses that do the same. Bio-metric data provide even better identification. And people get social credit scores, which determine eligibility for loans, travel and more. This artificial-intelligence-enabled system enables political repression and strengthens autocratic rule.
Today, a divided America needs to “get [its] act together as a country” regarding artificial intelligence said former Alphabet CEO Eric Schmidt. If it doesn’t, America’s greatness will pass, and so will hope for a free world order.
