Social Media Becomes the New Front In Mexico's Drug War

Wed, 02/04/2014 - 07:09
An anonymous reader writes "The drug cartels operating in Mexico have often been compared to large corporations, with their own codified leadership hierarchy, recruitment methods, and accounting practices. But part of any big corporation's playbook is a marketing/PR plan. The cartels have long operated a version of those, too, by threatening journalists and killing civilians who speak up. Like any corporation these days, the drug cartels have recognized the power of social media, and they're using it more and more to propagate their messages of intimidation and violence. Quoting: 'Six days after Beltran Leyva's death, gunmen murdered family members of the only Mexican marine killed in the apartment complex siege — including the marine's mother. That same day, a fire was set at a nearby school where a banner was flown, warning that more killings would follow if the federal government made any further attempts to interfere in cartel actions. Photos of the school were then tweeted and shared in status updates — a reply to images of Beltran Leyva's corpse being shared on social media.'"

Should Patients Have the Option To Not Know Their DNA?

Wed, 02/04/2014 - 05:04
An anonymous reader writes "Genome sequencing is getting faster and cheaper every year. This article points out that in the not-too-distant future, a DNA test will be a common diagnostic tool for doctors. It's a good thing for figuring out what's wrong with you — but there will unintended consequences. The test will also return information about conditions and diseases you're likely to get, which will spur more frequent testing — which can be extremely uncomfortable and/or expensive — as well as more frequent worrying. Should people be able to opt-out of this knowledge? Even if they do, should the information go into the patient's medical record? It likely will, and then the next doctor may be in the difficult position of not knowing what she can discuss with the patient. A new decision from the American College of Medical Genetics has recommended giving patients the option of not having the information gathered at all. It can get more complicated, too: '[G]eneticists and bioethicists are already discussing scenarios where patients may approach such decisions more like a menu, saying they want to know about increased risk of heart disease but not cancer, for example.'"

8.2 Earthquake Off the Coast of Chile, Tsunami Triggered

Wed, 02/04/2014 - 02:37
An 8.2-magnitude earthquake has struck roughly 60km off the cost of Chile. Its depth was approximately 20.1km. A tsunami has been generated, and evacuations have been ordered along the coast near the strike. Tsunami warnings were also issued for Peru and Ecuador. According to the Associated Press, "Coastal residents of northern Chile evacuated calmly as waves measuring almost 2 meters (6 1/2 feet) struck ahead of a tsunami that was expected to come ashore later. ... Chile's emergency service reported some roads blocked by landslides caused by the quake, but said no injuries had been reported so far."

How a 'Seismic Cloak' Could Slow Down an Earthquake

Tue, 01/04/2014 - 20:31
Daniel_Stuckey writes "The United States is currently gripped in a bout of earthquake mania, following a series of significant tremors in the West. And any time Yellowstone, LA, or San Francisco shakes, people start to wonder if it's a sign of The Big One to come. Yet even after decades of research, earthquake prediction remains notoriously hard, and not every building in quake-prone areas has an earthquake-resistant design. What if, instead of quaking in our boots, we could stop quakes in their tracks? Theoretically, it's not a crazy idea. Earthquakes propagate in waves, and if noise-canceling headphones have taught us anything, it's that waves can be absorbed, reflected, or canceled out. Today, a paper published in Physical Review Letters suggests how that might be done. It's the result of French research into the use of metamaterials—broadly, materials with properties not found in nature—to modify seismic waves, like a seismic cloaking device."

PortWineBoy writes: "The Beeb is reporting that OkCupid is prompting Mozilla Firefox users to switch browsers over Brendan Eich's support of Prop 8 in California in 2008. Users are met with a message stating that OKCupid would prefer no one access their site with Mozilla software. Eich is the new CEO of Mozilla."

Creating "Homo Minutus" — a Benchtop Human To Test Drugs

Tue, 01/04/2014 - 10:07
Science_afficionado (932920) writes "Vanderbilt University scientists reported significant progress toward creating 'homo minutus' — a benchtop human — at the Society of Toxicology meeting on Mar. 26 in Phoenix. The advance is the successful development and analysis of a human liver construct//organ-on-a-chip that responds to exposure to a toxic chemical much like a real liver. The achievement is the first result from a five-year, $19 million multi-institutional effort led by Los Alamos National Laboratory (LANL), to develop four interconnected human organ constructs — liver, heart, lung and kidney — that are based on a highly miniaturized platform nicknamed ATHENA (Advanced Tissue-engineered Human Ectypal Network Analyzer). The project is supported by the Defense Threat Reduction Agency. Similar programs to create smaller-scale organs-on-chips are underway at the Defense Advanced Research Projects Agency and the National Institutes of Health."
