NASA Telescope Reveals Largest Batch of Earth-Size, Habitable-Zone Planets Around Single Star

This illustration shows the possible surface of TRAPPIST-1f, one of the newly discovered planets in the TRAPPIST-1 system.
This illustration shows the possible surface of TRAPPIST-1f, one of the newly discovered planets in the TRAPPIST-1 system. Scientists using the Spitzer Space Telescope and ground-based telescopes have discovered that there are seven Earth-size planets in the system.


NASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.


The TRAPPIST-1 star, an ultra-cool dwarf, has seven Earth-size planets orbiting it.

The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water – key to life as we know it – under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”



At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets.

This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile. In May 2016, researchers using TRAPPIST announced they had discovered three planets in the system. Assisted by several ground-based telescopes, including the European Southern Observatory's Very Large Telescope, Spitzer confirmed the existence of two of these planets and discovered five additional ones, increasing the number of known planets in the system to seven. The new results were published Wednesday in the journal Nature, and announced at a news briefing at NASA Headquarters in Washington.

Using Spitzer data, the team precisely measured the sizes of the seven planets and developed first estimates of the masses of six of them, allowing their density to be estimated.

Based on their densities, all of the TRAPPIST-1 planets are likely to be rocky. Further observations will not only help determine whether they are rich in water, but also possibly reveal whether any could have liquid water on their surfaces. The mass of the seventh and farthest exoplanet has not yet been estimated – scientists believe it could be an icy, "snowball-like" world, but further observations are needed.

"The seven wonders of TRAPPIST-1 are the first Earth-size planets that have been found orbiting this kind of star," said Michael Gillon, lead author of the paper and the principal investigator of the TRAPPIST exoplanet survey at the University of Liege, Belgium. "It is also the best target yet for studying the atmospheres of potentially habitable, Earth-size worlds."


In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky.

The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes.

Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. In the fall of 2016, Spitzer observed TRAPPIST-1 nearly continuously for 500 hours. Spitzer is uniquely positioned in its orbit to observe enough crossing – transits – of the planets in front of the host star to reveal the complex architecture of the system. Engineers optimized Spitzer’s ability to observe transiting planets during Spitzer’s “warm mission,” which began after the spacecraft’s coolant ran out as planned after the first five years of operations.

"This is the most exciting result I have seen in the 14 years of Spitzer operations," said Sean Carey, manager of NASA's Spitzer Science Center at Caltech/IPAC in Pasadena, California. "Spitzer will follow up in the fall to further refine our understanding of these planets so that the James Webb Space Telescope can follow up. More observations of the system are sure to reveal more secrets.”

Following up on the Spitzer discovery, NASA's Hubble Space Telescope has initiated the screening of four of the planets, including the three inside the habitable zone. These observations aim at assessing the presence of puffy, hydrogen-dominated atmospheres, typical for gaseous worlds like Neptune, around these planets.

In May 2016, the Hubble team observed the two innermost planets, and found no evidence for such puffy atmospheres. This strengthened the case that the planets closest to the star are rocky in nature.

"The TRAPPIST-1 system provides one of the best opportunities in the next decade to study the atmospheres around Earth-size planets," said Nikole Lewis, co-leader of the Hubble study and astronomer at the Space Telescope Science Institute in Baltimore, Maryland. NASA's planet-hunting Kepler space telescope also is studying the TRAPPIST-1 system, making measurements of the star's minuscule changes in brightness due to transiting planets. Operating as the K2 mission, the spacecraft's observations will allow astronomers to refine the properties of the known planets, as well as search for additional planets in the system.

Ancient Aliens ??



Here is a photo of what looks like an astronaut on a pillar at Salamanca Cathedral Church, Spain. The church took nearly two centuries to build (1600s-1800s), but why then would they have carved such a figure into stone? What else could it possibly represent? An alien? Yikes!

Perched on a façade over the northern entrance of a 300-year-old cathedral in Salamanca, Spain, is a carved figure remarkably reminiscent of a modern astronaut. Construction of the cathedral was started in 1513 and completed in 1733.
Instantly, the mind questions what the eyes see. Theories of ancient aliens, time travel, or perhaps the sculptor had the supernormal power of foresight. And, although the world today still holds many mysteries, the mystery of the Salamanca Cathedral Astronaut has a much more down-to-earth explanation.
Salamanca, Spain, is home to two cathedrals. The “Old Cathedral,” simply known as “Catedral Vieja,” which was constructed in about the mid-12th century. As such, it may be one of the oldest cathedrals in Europe.
The other cathedral, known as the “Catedral Nueva” or “New Cathedral,” which is no longer new by today’s standards but was new when it was first called such.



It’s on the New Cathedral’s entrance that the astronaut appears, running laterally, parallel to the entrance. He sits perched on a stalk complete with boots, helmet, and what appears to be a breathing apparatus on his chest with tubes stretching to a pack on the rear of his suit. He is grasping with his right hand what appears to be a vine acting as a harness of sorts running across his waist. His left hand is grasping a nearby leaf for support. His face reflects a rather bewildered expression.
But, how could this be? Astronauts didn’t exist when the cathedral was constructed. It would appear that the carving is actually part of restoration that was done to the cathedral in 1992. At that time, the “Puerta de Ramos” (this is the name of the New Cathedral’s entrance) had seen significant damage over the past few centuries. The addition was purportedly added by stonemason Miguel Romero and possibly overseen by Jerónimo García de Quiñones, according to Ancient Code: Deciphering History Together. Following tradition, restoration on cathedrals often includes something from modern times, in this case, the restorers chose the figure of an astronaut.
But look at this:

Canadian military aircraft are once again over the skies of Syria



PERSIAN GULF — Canadian military aircraft are once again over the skies of Syria, doing necessary reconnaissance, identifying targets in the fight against the Islamic State of Iraq and the Levant months after the Liberals pulled fighter jets from the mission.
It has been one year since Canadian CF-18 fighter jets flew their last mission over Syria after the Liberals withdrew the planes in favor of a mission to train local Syrian forces and help rebuild areas affected by fighting. But responding to what the Canadian military saw as a need for more armed forces back-up, the Trudeau government is sending reinforcements back into the country.
While the revamped mission against ISIL includes a mandate to operate over Syria, military officials have been reluctant to confirm the scope of the new mission.
Canadian surveillance planes have flown hundreds of sorties to identify potential targets for coalition airstrikes, the majority of which have been in Iraq.
On Sunday, a senior Canadian commander revealed that the aircraft have also quietly flown dozens of times over Syria in recent months.
"We have done good  work in Syria," Brig.-Gen. Shane Brennan, commander of Canada's Joint Task Force-Iraq, told reporters during a media tour of the mission, though he added: "There's lots of work to do in Iraq. We are looking at all of the areas."
Brennan spoke at an airfield, the location of which the military didn't want revealed for security reasons, where reporters were given an exclusive tour of one the surveillance planes.
The CP140 Aurora was originally designed during the Cold War to detect Soviet submarines, but the design has since been upgraded to provide enhanced photos and other imagery of ground targets as well.

Canadian military intelligence officers at the base carefully review the images for targets, as well as schools, hospitals, mosques and other structures considered too sensitive to hit. When officers identify a target, they pass the information to coalition forces for additional verification before a strike mission is assigned.
The increased Canadian military activity over Syria, which Brennan described as between 20 and 30 missions in the past couple of months, is one indication that the war against ISIL is shifting into a new phase.

As Brennan heaped praise on the work of Canadian and Iraqi troops, Iraqi forces were launching their long-awaited assault on western Mosul.
The battle, which comes about a month after Iraqi forces declared the eastern part of the city free of ISIL, has been billed as a defining moment in eventually freeing Iraq from the extremist group's grip.
While the fight for the city's western half is expected to be much harder than what came before, Brennan was adamant that victory was a certainty
"There is a battle that is ongoing and will be won," Brennan said. "It's an inevitable event."

Less certain is what role Canadian troops will play when the current mandate, which also includes a military hospital, special forces troops and a helicopter detachment in northern Iraq, expires in March.
Military commanders are drawing up options based on a number of factors, including the expectation that ISIL will become a traditional insurgency in Iraq, which would require more police and counter-terrorism forces.
Canadian Brig.-Gen. David Anderson, who is leading an international team of military advisers in Iraq's defence ministry, said his group recently submitted a two-year plan focused on exactly that.

There are also concerns that the group will try to spread outside Iraq and Syria, which is why Canada is helping to strengthen border security in Jordan and Lebanon.
The military will present three options for the government to choose from in the coming weeks in deciding the future of the mission.

Yet one big wild card is what direction the U.S. military will go after President Donald Trump blasted the slow progress of the fight against ISIL and ordered a 30-day review to consider new options.
U.S. Defence Secretary James Mattis is expected to visit Iraq in the next week or so before presenting his recommendations later this month.
Exactly what Mattis will recommend, both in Iraq and Syria, is wide open for speculation.
Brennan said the results could have a big impact on what Canada decides to do given the need to ensure a unified and co-ordinated international effort in the fight against ISIL.
"It does depend what happens," Brennan said. "We are waiting as well. I think the question is: What else needs to be done, or could be done?"

Trump puppets defend his media paranoia - Look out first ammendment




[Amendment I: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.]

Definition of 'Freedom of the Press' : The right to circulate opinions in print without censorship by the government. Americans enjoy freedom of the press under the First Amendment to the constitution.

While most Trump clones are dancing to his tune and a couple are balancing on the fence, one or two are politely disagreeing with his paranoid attacks on the press.
Don't be surprised if he tries to legislate some kind of state control over the media like his beloved Putin.
Donald Trump's defense secretary has distanced himself from the president's war on media, calling journalists a constituency of the democratic process.
James Mattis' comments came after his commander-in-chief declared the fifth estate the "enemy of the American people" and vowed to "expose them for what they are".
"The press, as far as I'm concerned, are a constituency that we deal with," Mr Mattis said. "And I don't have any issues with the press, myself."

Mr Trump often mocked the "dishonest" media in his presidential campaign.  But since taking office, this denigration has morphed from crowd pleasing rhetoric into a strategy seemingly intended to discredit journalists reporting unflattering revelations of dysfunction and divisions in his White House.
Reince Priebus, the White House chief of staff warned yesterday that Trump's comments, which often come in the form of missives fired on Twitter, should be taken "seriously". He described political reporting on Mr Trump's first month -  the most drama-riven of perhaps any presidency - as a "feeding frenzy" of "bogus" stories.
Mr Priebus attacked as "total garbage" the media coverage of allegations that the Trump campaign may have colluded with Moscow's alleged interference in the US election, despite this also being the subject in of a senate intelligence committee investigation.
He said journalists should report that Mr Trump "has accomplished more in the first 30 days in this presidency than people can remember in a long time", ( more what? ) a claim that, when  these first weeks are compared to those of Barack Obama's, his predecessor, does not stand up to scrutiny. ( keep dancing Mr Priebus)
On CBS' 'Face the Nation' Mr Preibus dogged focus on the dishonesty of the press, prompted anchor John Dickerson to say: "So in every answer, you've turned it back to the media. So I guess the question is: Is the strategy now to answer any question by just turning it back on the media and using a fight with the media as a way to try to control the storyline?" ( keep in step Mr Priebus)
The president has taken  to collectively dismissing major US television networks and newspapers as the "fake news media", describing them as "lying", "corrupt" and "failing", the "enemy" and the "opposition".

These attacks have drawn scathing criticism from US politicians,  a few, even within Republican ranks. Lindsey Graham, a prominent conservative senator from South Carolina said on CBS that a free press and independent judiciary "is worth fighting and dying for".
He said he believed US media had become a little "hysterical" in its reporting of Mr Trump, but that: "The enemies of the democracy at the end of the day are not the press. It's Russia. It's Iran and radical Islam."
His comments came a day after John McCain, the veteran Republican senator from Arizona, echoed the warnings being made by Democrats in congress that Mr Trump's is taking a strong man approach to the Oval office.
"If you want to preserve democracy as we know it, you have to have a free and many times adversarial press," he said. "And without it, I am afraid that we would lose so much of our individual liberties over time. That's how dictators get started."

Marco Rubio, the Florida senator who ran against Mr Trump for the Republican nomination in the election, but who has since been careful not to criticize the president answered a question about whether Mr Trump was damaging America's image abroad by saying "a country's more than one person". But there is only one out there on center stage in the world's spotlight and he is the standard by which America is judged.

Separately, reports emerged that Mr Trump plans to issue an executive order enacting a new version of his controversial immigration and travel ban on Tuesday. A draft seen by the Wall Street Journal, shows that the administration would try to keep the temporary travel ban from seven Muslim-majority countries. Green-cards will be exempted.
A state department official suggested that the controversial policy would be dropped, but two White House officials denied the claims. Most people believe Mr Trump will bring it to pass somehow.

Utah Republican argues against equal pay for women: It’s ‘bad for families’ and society

Snow rests on the sign on the Utah state Capitol on the opening day of the 2017 session in Salt Lake City, Jan. 23.





In a letter criticizing a bill that addresses pay gap in the workforce, a Utah Republican said that men have traditionally earned more than women and, citing “simple economics,” argued that things should stay that way.
James Green’s letter to the editor, published in two local publications earlier this week, immediately prompted such outrage that within two days, Green had written an apology and resigned from his post as vice chair of the Wasatch County Republican Party.
Green said in his letter, published Wednesday by the Park Record and the Wasatch Wave, that men make more than women because they’re “the primary breadwinners” of their families, and paying women equally would somehow ruin the makeup of a traditional family where “the Mother” remains at home raising children.
“If businesses are forced to pay women the same as male earnings, that means they will have to reduce the pay for the men they employ, simple economics,” Green wrote. “If that happens, then men will have an even more difficult time earning enough to support their families, which will mean more Mothers will be forced to leave the home (where they may prefer to be) to join the workforce to make up the difference.”

And having more women in the workforce would create competition for jobs, “even men’s jobs,” Green wrote. That will, in turn, lower the pay for all jobs and force “more and more Mothers” into the workforce, he argued.
That’s “bad for families and thus for all of society,” Green wrote. “It’s a vicious cycle that only gets worse the more equality of pay is forced upon us. It’s a situation of well-meaning intentions, but negative unintended consequences.”


Green’s comments were directed at Senate Bill 210, which would make changes to laws related to employee pay in the state. The bill, authored by state Sen. Jacob Anderegg, a fellow Utah Republican, would commission a study on whether there’s a pay gap between male and female workers in the state. It would require certain employers to adopt a uniform criteria that will be used to determine whether someone should get a raise based on performance, and would create a pay index that states the average pay range for each occupation based on years of experience.
SB 210 was introduced on Monday.


Shortly after its publication, Green’s letter was met with a sharp response.
State Rep. Tim Quinn, a Republican who represents Utah’s 54th district, which includes Wasatch County, denounced the comments and distanced himself from Green. Wasatch County, with a population of a little more than 29,000, is located about 100 miles outside of Salt Lake City.
“I am shocked and appalled to learn how James Green feels about equal pay for women. I don’t know where this belief came from,” Quinn said in a statement, according to Fox affiliate KSTU. “I do not subscribe publicly or privately to the words or the spirit behind these words, thoughts or ideas. Of course, the Wasatch County Republican Party and I are for equal pay and rights for all people.”
The Utah Women’s Coalition, which supports SB 210, took to social media with its criticism of Green’s comments.
“Are we really having this conversation in 2017?” asked a Facebook post sharing a local story about Green.


The coalition’s Stephanie Pitcher told Fox affiliate KSTU that the bluntness of Green’s remarks were “very disappointing” and contradicts the federal Fair Labor Standards Act, as well as anti-discrimination provisions in state law.
“He was very straightforward and blunt about his thoughts on women in the workforce and that was really surprising, but the first thing I noticed was a very open recognition that there is a pay disparity between men and women,” Pitcher told KSTU of Green.
Green did not return a call from The Washington Post on Saturday. But he told KSTU that he has been in “hot water” since his letter was published.
“You wouldn’t believe the hateful, vile comments and messages I’ve received," adding that he decided to resign from his position as vice chair of the Wasatch County GOP because he “didn’t want to hurt the party,” which he said was getting blamed for his comments.


Green then wrote a second letter saying his comments are not representative of the Wasatch County GOP or the Republican Party in general and apologizing to those who have been offended.
“I want to clarify that the main focus of my letter was to express that I don’t feel the government should be dictating to private establishments what they must do in regard to employment, hiring, or wages,” Green wrote. “There was no offense intended toward Women, whatsoever. And yet some took it that way. To those who were offended, I profusely apologize. I sincerely did not mean to do that.”
He also said he values women’s contributions in the workforce, and that he was only pointing out the “historical reasons for pay disparity.”
“While I worked my fingers to the bone (with numerous extra side jobs) so my Wife could say in the home and raise our two Sons, who are now both Physician/Surgeons (plus one also has a Law Degree), I realize not everyone is so fortunate,” Green wrote.
A spokeswoman for the Utah GOP said on Friday afternoon that Green had resigned. Efforts to reach the Utah GOP on Saturday were unsuccessful.


Women in Utah make 71 cents for every dollar paid to men for the same occupation, according to the National Women’s Law Center. That’s lower than the national average, which is 80 cents for every dollar paid to men.
Black and Latina women in the state make 56 cents and 47 cents for every dollar paid to white men, respectively, according to the center. Both numbers are below the national averages: 63 cents for black women and 54 cents for Latina women.
Politicians have repeatedly pointed out that women make less than men. But as The Post’s Glenn Kessler pointed out last year, the specific number on the pay difference is an overused “factoid” that has become a major talking point for Democrats but fails to capture some of the nuances in the workforce.
Although few experts dispute the existence of a pay gap, that number does not take into account differences in life choices between men and women — such as women tending to leave the workforce when they have children, Kessler wrote.

Woolly mammoth on the verge of resurrection, scientists say


 
Woolly mammoth (Mammuthus primigenius), a model of an extinct Ice Age mammoth. Scientists are aiming to produce a hybrid elephant-mammoth embryo.
 


The woolly mammoth vanished from the Earth 4,000 years ago, but now scientists say they are on the brink of resurrecting the ancient beast in a revised form, through an ambitious feat of genetic engineering.
Speaking ahead of the American Association for the Advancement of Science (AAAS) annual meeting in Boston this week, the scientist leading the “de-extinction” effort said the Harvard team is just two years away from creating a hybrid embryo, in which mammoth traits would be programmed into an Asian elephant.
“Our aim is to produce a hybrid elephant-mammoth embryo,” said Prof George Church. “Actually, it would be more like an elephant with a number of mammoth traits. We’re not there yet, but it could happen in a couple of years.”
The creature, sometimes referred to as a “mammophant”, would be partly elephant, but with features such as small ears, subcutaneous fat, long shaggy hair and cold-adapted blood. The mammoth genes for these traits are spliced into the elephant DNA using the powerful gene-editing tool, Crispr.

Until now, the team have stopped at the cell stage, but are now moving towards creating embryos – although, they said that it would be many years before any serious attempt at producing a living creature.
“We’re working on ways to evaluate the impact of all these edits and basically trying to establish embryogenesis in the lab,” said Church.

Since starting the project in 2015 the researchers have increased the number of “edits” where mammoth DNA has been spliced into the elephant genome from 15 to 45.
“We already know about ones to do with small ears, sub-cutaneous fat, hair and blood, but there are others that seem to be positively selected,” he said.
The eminent geneticist also outlined plans to grow the hybrid animal within an artificial womb rather than recruit a female elephant as a surrogate mother.

The woolly mammoth roamed across Europe, Asia, Africa and North America during the last Ice Age and vanished some 4,000 years ago, probably due to a combination of climate change and hunting by humans. Their closest living relative is the Asian, not the African, elephant.

“De-extincting” the mammoth has become a realistic prospect because of revolutionary gene editing techniques that allow the precise selection and insertion of DNA from specimens frozen over millennia in Siberian ice. Church helped develop the most widely used technique, known as Crispr/Cas9, that has transformed genetic engineering since it was first demonstrated in 2012.

Derived from a defence system bacteria use to fend off viruses, it allows the “cut and paste” manipulation of strands of DNA with a precision not seen before.
Gene editing and its ethical implications is one of the key topics under discussion at the Boston conference.

Church, a guest speaker at the meeting, said the mammoth project had two goals: securing an alternative future for the endangered Asian elephant and helping to combat global warming.
Woolly mammoths could help prevent tundra permafrost from melting and releasing huge amounts of greenhouse gas into the atmosphere.
“They keep the tundra from thawing by punching through snow and allowing cold air to come in,” said Church. “In the summer they knock down trees and help the grass grow.”

A simulated ecosystem study has indicated that mammoths in Siberia could cause local temperatures to drop by up to 20C.
The scientists intend to engineer elephant skin cells to produce the embryo, or multiple embryos, using cloning techniques. Nuclei from the reprogrammed cells would be placed into elephant egg cells whose own genetic material has been removed. The eggs would then be artificially stimulated to develop into embryos.

Referring to the artificial womb, Church said: “We hope to do the entire procedure ex-vivo (outside a living body). It would be unreasonable to put female reproduction at risk in an endangered species.
“We’re testing the growth of mice ex-vivo. There are experiments in the literature from the 1980s but there hasn’t been much interest for a while.
“Today we’ve got a whole new set of technology and we’re taking a fresh look at it.”

Church predicts that age-reversal will become a reality within 10 years as a result of the new developments in genetic engineering. Just imagine that.

Blame social media, video games for behavior problems in school, educators say




Growing up in the social media age is doing more harm than good, according to a school counsellor on the northeast Avalon. Boyd Perry said having access to a limitless world of information can be beneficial to learning, but many young kids are not equipped to handle the flood of information they are getting through their screens.
"Young people have more access and more information. We automatically think that's a good thing," said Perry.
"They aren't yet ready … to develop a critical way of analyzing the information they are getting."

During CBC's education forum, Inside the Classroom, featuring 30 educators from across the province, several teachers and counsellors raised issues about social media, video games, and their impact on student behaviors.
"A lot of the problems we have in school are because of social media," said Joe Santos, a high school teacher on the northeast Avalon.
"There's very few students now in schools that don't have some kind of device they can communicate with."

Students are speaking behind each other's backs and sometimes making sinister plans in total silence — out of earshot from intervening teachers.
Santos said some of the issues they've encountered range from settling scores with violence, to making drug deals, all arranged quietly through the use of cell phones in school.

Technology raised concerns with other teachers as well, who spoke of students coming to class zonked after long nights of video gaming.
"They're too tired to learn," said Kimberly Fifield, an elementary school teacher on the northeast Avalon.
"They could fall asleep in class, they could become agitated, they're more irritable. They're just unable to focus on what you're trying to teach them in the run of a day."

According to Santos, attendance rates go down after the release of a highly anticipated video game, as his students stay up all night to finish the game. The long hours spent playing video games, sometimes graphic and violent, can have an impact over time, said Angela Wilmott, a school counsellor in central Newfoundland.
"If you're role playing war games for hours every day, it has an impact in how your brain is working and how you're dealing with stress and anxiety," she said.

While there is some scientific debate over the impact of video game addiction, several studies have linked playing for excessive hours with issues like depression, anxiety, and attention deficit disorder. Whether gaming is causing the disorders, or is simply an outlet for kids with those disorders, is unproven.

Video games could also be partially responsible for the language kids are using, Wilmott said. Kids play interactive games like Call of Duty or Grand Theft Auto, where their online teammates and opponents could be adults. Wilmott said she worries about the kids being exposed to vulgar language through those interactions.
"That's becoming much more common," she said. 
"To see that now in primary, elementary… Where are those kids going to be in Grade 11?"

It's a question Perry also ponders, as he sees students at his school being consumed by technology.
"We see that shift [to the social media age] and think they are so much more exposed to things, but they are not ready to handle the sorts of things they are exposed to," he said.
 I think many parents are in agreement that the information and technology over-load our kids are subject to has as many negative as positive influences. It may confuse them and skew children's judgement when they don't have the time necessary to process and absorb information at their own pace.  Most of the video games are too mature or violent and take children too far away from reality while they play. I think they can confuse or mingle the real world with the cyber world. I also feel we are stealing some of their childhood by not letting them just be kids for the brief time they are allotted. By flooding their minds with adult information are we not stealing the wonder and magic of being a child and the wonder of self discovery???
