Overeager Investors Seeking Snap Buy Snap Interactive Instead (cnet.com) 55

Posted by msmash from the weird-story-of-the-day dept.
Stephen Shankland, writing for CNET: Investors eager to cash in on the initial public offering of Snap, makers of the popular Snapchat app, have instead been buying shares of Snap Interactive, maker of the Paltalk video chat app and FirstMet dating app. Snap Interactive stock, traded over the counter and not on major exchanges like Nasdaq, has slid below $6 per share in recent years, according to Google Finance. On Monday, after Snap detailed its IPO plans, though, its stock surged to $15 and remained between $8 and $10 per share Wednesday.

Injecting Liquid Metal Into Blood Vessels Could Help Kill Tumors 111

Posted by Unknown Lamer from the accidentally-colossus dept.
KentuckyFC (1144503) writes One of the most interesting emerging treatments for certain types of cancer aims to starve the tumor to death. The strategy involves destroying or blocking the blood vessels that supply a tumor with oxygen and nutrients. Without its lifeblood, the unwanted growth shrivels up and dies. This can be done by physically blocking the vessels with blood clots, gels, balloons, glue, nanoparticles and so on. However, these techniques have never been entirely successful because the blockages can be washed away by the blood flow and the materials do not always fill blood vessels entirely, allowing blood to flow round them. Now Chinese researchers say they've solved the problem by filling blood vessels with an indium-gallium alloy that is liquid at body temperature. They've tested the idea in the lab on mice and rabbits. Their experiments show that the alloy is relatively benign but really does fill the vessels, blocks the blood flow entirely and starves the surrounding tissue of oxygen and nutrients. The team has also identified some problems such as the possibility of blobs of metal being washed into the heart and lungs. Nevertheless, they say their approach is a promising injectable tumor treatment.

Submission + - NSA broke privacy rules thousands of times per year, audit finds" (washingtonpost.com)

NettiWelho writes: The Washington Post: The National Security Agency has broken privacy rules or overstepped its legal authority thousands of times each year since Congress granted the agency broad new powers in 2008, according to an internal audit and other top-secret documents.
Most of the infractions involve unauthorized surveillance of Americans or foreign intelligence targets in the United States, both of which are restricted by law and executive order. They range from significant violations of law to typographical errors that resulted in unintended interception of U.S. e-mails and telephone calls.

Falcon 9 Prepares For High Stakes Launch 190

Posted by Soulskill from the take-us-out-of-the-world dept.
happylunarnewyear writes "The first new rocket to be launched from the Cape since 2002 is assembled and upright on Launch Complex 40. Falcon 9 will undergo fueling testing and live firing tests before the launch occurs as soon as next month. The stakes couldn't be higher, either. The much politicized proposal for a change in direction for NASA, which includes scrapping the Constellation program in toto in favor of privatization and a new heavy lift vehicle, veritably rides on this rocket. If the launch goes well, the plan for increased reliance on privatized cargo missions and eventually privatized manned missions will soar with it. However if something goes wrong, those plans will come crashing to Earth along with Falcon 9. Given the stakes, this launch is one of the most important in recent history. From the article, 'President Obama's proposal to shift transport of US astronauts to the space station from government launchers to privatized ones could suffer politically if there's a high-profile problem with the first mission of the Falcon 9, by far the most talked-about newcomer vying for the opportunity.'" Reader FleaPlus contributes related news about NASA's proposed funding for scientific payloads on commercial space flights, which would be a huge boon to researchers.

All Humans Are Mutants, Say Scientists 309

Posted by timothy from the must-scramble-some-eggs dept.
Hugh Pickens writes "In 1935, JBS Haldane, one of the founders of modern genetics, studied a group of men with the blood disease hemophilia and speculated that there would be about 150 new mutations in each human being. Now BBC reports that scientists have used next generation sequencing technology to produce a far more direct and reliable estimate of the number of mutations by looking at thousands of genes belonging to two Chinese men who are distantly related, having shared a common ancestor who was born in 1805. To establish the rate of mutation, the team examined an area of the Y chromosome which is unique because, apart from rare mutations, the Y chromosome is passed unchanged from father to son so mutations accumulate slowly over the generations. Despite many generations of separation, researchers found only 12 differences among all the DNA letters examined. The two Y chromosomes were still identical at 10,149,073 of the 10,149,085 letters examined."
