When artists are on the frontlines – of peaceAfter seven decades of separation and frequent conflicts, the people of North and South Korea have grown so far apart that many observers say they can never reunite. Kang Chun-hyok, a well-known hip hop artist, thinks otherwise. A defector from North Korea who now lives in Seoul, he writes songs that show the common bonds of Koreans. His latest rap single, "For the Freedom," is the kind of artistic expression he hopes will prepare Koreans for reunification – despite the current saber-rattling around the divided peninsula.

Erdogan: Turkey's pugnacious 'chief' wins againIf there were a global contest for winning elections, Turkey's President Recep Tayyip Erdogan would see himself as the undisputed -- and undefeated -- heavyweight champion of the world. In the 15 years since his ruling party came to power, Erdogan has taken part in 11 elections -- five legislative polls, two referenda, three local elections and a presidential vote -- and won them all. On Sunday, Erdogan claimed victory in his 12t and arguably biggest ballot-box challenge since his ruling Justice and Development Party (AKP) came to power in 2002: a referendum on expanding his powers.

"Many illegal acts are being carried out in favor of the government right now, but 'No' will win in the end," Erdal Aksunger told reporters at his party headquarters, referring to an election board decision to accept unstamped ballots. A statement on the High Electoral Board's (YSK) website hours before polls closed said it would count ballots that had not been stamped by its officials as valid unless they could be proved fraudulent, citing a high number of complaints that YSK officials at polling stations had failed to stamp them.


Facebook shareholders propose reports on 'fake news', pay equality

Posted: 14 Apr 2017 08:30 PM PDT

Facebook shareholders propose reports on 'fake news', pay equalityShareholders have proposed that Facebook Inc prepare a report on the threat to democracy and free speech from so-called fake news spread on the social media forum, and the dangers it may pose to the company itself, according to a proxy filing made on Friday. The proposal, which said Facebook had provided "a financial mechanism supporting fabricated content" on the internet, suggests the company review the issue broadly, including the extent to which it blocks fake posts, how its strategies impact free speech and how it evaluates claims in posts. "Facebook is highly vulnerable, as fake news promoters are spamming their way to visibility for fake news through strategically gaming Facebook's algorithms and publishing platform," the proposal states.

Science proves that training AI to be ‘human’ makes it sexist and racist, too

Science proves that training AI to be 'human' makes it sexist and racist, too

As we get closer and closer to create artificial intelligence that can think and reason in ways that mimic a human brain it's becoming increasingly clear that allowing a machine mind to learn from humans is a very bad idea. We've seen examples of it in the past, but a new study on AI biases reveals that not only does training an artificial brain create biases, but those leanings reinforce many societal issues regarding race and gender that plague humanity today. 

The study, which was conducted by scientists at Princeton University and published in the journal Science, sought to determine not just if the behavior of an AI exhibited specific biases, but whether the machine learning systems that determine the outcome inherently lean one way or the other. To do this, the team trained an AI using standard datasets that are popular choices for machine learning. These kinds of sets include millions of words and are often gathered from many sources, including the internet.

The AI studies the words, how their used, and what words they're used in association with, in order to provide natural language responses and answers in a way that we can understand. It also, as it turns out, learns some of our more unfortunate quirks.

After training the AI, scientists tested how it associates various words with others. For example, "flower" is more likely to be associated with "pleasant" than "weapon" is. That, of course, makes perfect sense. However, the trained AI also had a habit of associating typically caucasian-sounding names with other things that it considered to be "pleasant," rather than African-American names. The AI also shied away from pairing female pronouns with mathematics, and instead often associated them with artistic terms.

This is obviously a huge issue since, in the name of creating AI that sound and behave more human, some of the standard training materials being used carry with them some of the worst parts of us. It's a very interesting problem, and one that you can bet will get a lot of attention now that evidence seems to be mounting.

NASA photos capture a strange new crack in a massive Greenland glacier and we're all probably doomed

Posted: 16 Apr 2017 06:52 AM PDT

NASA photos capture a strange new crack in a massive Greenland glacier and we're all probably doomedA mysterious crack has been spreading across a giant Greenland glacier, and it's raising concerns that part of the floating ice shelf could splinter off into the ocean.  That's bad.  Scientists with the NASA field campaign Operation IceBridge recently captured the first photographs of the growing rift while flying over Petermann Glacier, a structure that connects the Greenland ice sheet to the Arctic Ocean. SEE ALSO: NASA photo reveals a startling 300-foot-wide rift in Antarctic Ice Shelf The new chasm appears in the center of the glacier's floating ice shelf — the tongue of ice that extends into the water from the grounded glacier on land.  In the photos, the crack appears relatively close to a larger rift spreading toward the shelf's center. Should the two intersect, part of the ice shelf in northwest Greenland could potentially break off. A portion of the new rift on Petermann Glacier's floating ice shelf is shown near the bottom center. The older rift appears near top center. The shaded feature, near the bottom center, is the "medial flowline."Image: NASA/Kelly BruntThere may be a savior for the shelf. A "medial flowline" in the ice could have a "stagnating effect" on the newer rift, helping to slow or halt its advance toward the older chasm, scientists with Operation IceBridge said on Facebook. Stef Lhermitte, a professor at Delft University of Technology in the Netherlands, first alerted the NASA team to the crack's coordinates after spotting it in satellite images, Washington Post reported. Polar-orbiting satellites showed the chasm for the first time in July 2016, and "it has been growing since then," Lhermitte said on Twitter.  .@Petermann_Ice @AndreasMuenchow @glacier_doc @CopernicusEU @ESA_EO The internal crack growth is clearly visible in this Sentinel-1 time series, also during polar night. 3/5 pic.twitter.com/AKY2czWFtR — Stef Lhermitte (@StefLhermitte) April 12, 2017 While scientists still aren't sure what caused the crack to form, Lhermitte said a possible culprit might be "ocean forcing," a phenomenon that happens when warm ocean waters melt the ice from underneath. Ocean forcing might have been a culprit in creating cracks in another part of the world. Researchers believe it caused deep subsurface cracks to form in Antarctica's Pine Island Glacier, a recent study found. There a 20-mile-long rift eventually split the ice from the inside out and cleaved off a 225-square-mile iceberg in July 2015. Many of the glaciers in Greenland and Antarctica that end in floating ice shelves have been shrinking due to warming ocean and air temperatures. Petermann Glacier's east wall near the terminus of the floating ice shelf.Image: NASA/John SonntagWhen ice shelves break off into icebergs it doesn't directly increase sea levels, because the ice is already floating in the ocean, like an ice cube in a glass. However, because the ice shelves act like doorstops to the land-based ice behind them, if the shelves disappear, the glaciers can start moving into the sea. This would add new water to the ocean and therefore raise sea levels. In the case of Antarctica's Pine Island Glacier, researchers said that warming waters causing cracks to form beneath "provides another mechanism for rapid retreat of these glaciers, adding to the probability that we may see significant collapse of West Antarctica in our lifetimes." Greenland, Antarctica, the message is we're all probably doomed.  WATCH: Watch how global warming heats up the world from 1880-2016

Police in Sarasota County, Florida, shared photos Wednesday of a rogue alligator that, while wandering a neighborhood, trudged right up to the front door of a house. It later tried its luck at the garage door, too, but no one let it in. Imagine! SEE ALSO: Fisherman finds a terrifying surprise at the end of his line We do not think it was invited.

Stay safe out there, Floridians," the post from the sheriff's office read.  While non-Floridian commenters were largely horrified, others — including Florida residents — didn't seem too surprised by the photos. "I'd rather open my door and see this out as opposed to a [water moccasin]!" one commenter wrote. Still, if this gator was going to stop by uninvited, it could have at least brought flowers.
