Public debate on the effects of violent video games can become especially contentious in the wake of a rampage shooting, such as the recent killing of nine people in Munich. If it is later discovered the perpetrator was a fan of violent video games, as was the Munich killer, it is tempting to think that perhaps violent games'caused' the rampage shooting. But rampage shootings are rare and complex events caused by multiple factors acting together. One can't accurately predict a rampage shooting based on exposure to violent video games or any other single factor. Laboratory experiments are used to make firm and causal conclusions about violent video game effects.

DRUGS that change the chemistry and structure of the brain could boost the intelligence of people with Down's syndrome. Several compounds have improved memory and learning in a mouse version of the condition, suggesting that its cognitive effects can be changed. Until recently, this idea was unthinkable, says Mara Dierssen at the Centre for Genomic Regulation in Barcelona, Spain. Such efforts to improve brain function are controversial, with some activists saying people should be valued as they are. But some families have decided to give their children drugs like Prozac that have not yet been thoroughly tested for Down's syndrome.

Apps like Tinder were designed to make the process of dating quicker and more efficient, by only matching people with other who are interested in them to save people from rejection. But new evidence suggests the apps have created a different kind of problem – men play Tinder like a game, swiping right to everyone just to see who has'liked' them. This can be frustrating for women, who are pickier about who they match with, since men they are paired with are less likely to reply to their messages, a new study has found. Evidence shows people on Tinder are not motivated enough to speak to someone they match with. Both men and women are unlikely to message even after mutually liking another profile, a new study has found.

Business is booming at Google's parent company, Alphabet, even as it loses billions of dollars on kooky-sounding projects that may never produce any revenue. Most of the losses are concentrated in Alphabet's'X'' lab, a wellspring of far-out ideas that has become known as a'moonshot factory' since Google co-founder Sergey Brin launched it about six years ago. The lab is responsible for some once-zany projects, such as Google's self-driving cars, that matured into potentially revolutionary technology. FILE - In this Monday, Feb. 1, 2016, file photo, electronic screens post prices of Alphabet stock at the Nasdaq MarketSite in New York. Business is booming at Google¿s parent company, Alphabet Inc., even as it loses billions of dollars on risky projects that may never produce any revenue.

There was a primitive ocean on Mars that held more water than our Artic Sea and alien hunters believe to have spotted signs that life once inhabited the ancient sea. Nestled in the dust of the Gusev crater, appears to be a round broken sea shell that could be'evidence of Mars having an ocean with living creatures'. This is the second sighting of a sea shell this week and, combined with the fossilized fish seen in the dust, conspiracy theorists believe this is proof life did in face exist on the red planet. Nestled in the Gusev crater appears to be a round broken shell that could be'evidence of Mars having an ocean with living creatures' seen in images from the Nasa Curiosity Rover. Pareidolia is the psychological response to seeing faces and other significant and everyday items in random stimulus.

Online giant Amazon said it profit in the second quarter surged ninefold to 857 million, lifted by cloud services as the tech giant expanded its offerings. Revenues jumped 31 percent to 30.4 billion, Amazon said in stronger-than-expected results. While Amazon developed a reputation for delivering little or no profit in its retail operations, its earnings have been growing over the past year as it expands into video and new delivery services and boosts its cloud computing unit, Amazon Web Services (AWS). Revenues jumped 31 percent to 30.4 billion, Amazon said in stronger-than-expected results The second annual Prime Day was the biggest day ever for Amazon, and was also a record day for Amazon devices globally. Compared to Prime Day 2015, worldwide orders grew by more than 60%, orders from third-party sellers with Prime Day deals nearly tripled, and Prime members saved over twice as much on deals.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

Migratory birds use warm, rising currents of air to gain height using little energy to fly over long distances. But just how they navigate the height-boosting currents was a mystery, until now. Now, biologists have used mathematical models to demonstrate birds use'torque and vertical wind' to help them pick the most efficient soaring path through thermals. High fliers: Biologists have used mathematical models to demonstrate birds such as eagles (stock image) use'torque and vertical wind' to help them pick the most efficient soaring path through thermals Most migrating birds fly between 656 and 3,937 feet (200 to 1,200 metres) above sea level. When the wind s against them, they stay closer to Earth when obstacles like trees slow the wind down.

The combination of big data and machine learning is a revolutionary technology that can make a great impact on any industry if used in a proper way. In the field of healthcare it has great usage in cases like early disease detection, finding signs of early breakouts of epidemics, using clustering to figure out regions of epidemics (e.g. In this article, I have tried to explore the prediction of the existence of heart disease by using standard machine learning algorithms, and the big data toolset like Apache Spark, parquet, Spark mllib, and Spark SQL. The source code of this article is available on GitHub here. Also, you can check out the entire eclipse project from here.
