Arsenic. Hearing the word in America usually brings up black and white mental images of the film "Arsenic and Old Lace." Yet, it is not an old issue. People around the world are exposed to dangerous levels of arsenic in their water.
Speaking today at the American Geophysical Union, Lex van Green discussed the issue of arsenic in well water in the Asian sub-continent, primarily in Bangladesh and Bihar, India. His concern is that even though people are aware of the problem, very little is being done to address it.
People continue to drill new wells without determining their safety (safe levels are set at less than 10 micrograms per liter of water). Van Green's data, collected from 2012-13, show that 50% of people in the area assessed drink water containing arsenic at unsafe levels. However, 100% of people live near safe wells. Additionally, only about a third of people who become aware that their wells are contaminated switch to new wells by either drilling new wells or using their neighbor's wells.
The difference between a safe well and an arsenic contaminated well is depth. Sedimentation by ancient arsenic rich waters along river deltas left layers of arsenic containing soil near the surface of the Earth. To get past the arsenic to clean aquifers, one has only to drill deeper than 100 meters down. However, wells are expensive to drill, and the deeper the well, the more expensive it will be.
So, the problem in these areas where there is no infrastructure to deliver treated water to people boils down one of inequality. Read the rest
A newspaper photographer reporting on a TGI Friday's flying "Mobile Mistletoe" drone had her face sliced open by the 23" drone's six bare rotors, and Friday's blamed her for the injury, saying she flinched when the restaurant's drone pilot landed a smaller copter on her outstretched hand.

In his Sunday Observer column, John Naughton makes an important point that's hammered home by the escape of the NSA/GCHQ Regin cyberweapon into the wild: spies who make war on the Internet can't be trusted with its security. Read the rest
An exquisitely researched and endlessly fascinating long article tells the history of Brazil's centuries-old baloeiro craft, whereby painstakingly handmade paper balloons are lofted trailing ladders of pyrotechnics and long banners, powered by melted-down candle-stubs from churches and graveyards, cheered on by sometimes violent gangs who labor over them for months before releasing them.

In British-ruled, cobra-infested India, a bounty was offered for cobra-skins, so enterprising folks started breeding cobras, leading to the program's cancellation, whereupon all those farmed cobras were released into the wild, a net increase in cobra population. That's not the only example, either.
On Crooked Timber, Ingrid Robeyns presents a tough moral calculus: if you can save 50% of a group of trapped miners with 100% certainty, knowing the remainder will die; or you can try to rescue all the miners, with a 50% chance that they'll all die, which would you choose (And then: what if they were babies, not miners?)

Volkswagen and ad agency Ogilvy Beijing created this powerful and sneaky PSA for moviegoers in China, to warn of the dangers of being distracted by your smartphone while driving. We don't know that the footage is genuine, but even it not--it's a powerful concept. More at Ads of the World.
The respected Crimes Against Children Research Center reports that one in seven children is sexually exploited online. This figure is both credible and alarming. But the context is vital: as danah boyd writes, the average predator isn't a twisted older man trawling for kids; rather, "most children are sexually solicited by their classmates, peers, or young adults just a few years older than they are."
Now, it's absolutely possible for a child to sexually exploit another child, so this isn't to minimize the potential harm to kids. But for so long as we model the threat to kids as being weird, strange grownups, rather than the young people they know and see every day, we will fail to prepare them to comport themselves wisely and safely.
