A service of the American Association for the Advancement of Science.60webmaster@eurekalert.org (EurekAlert!)(<i>World Vision</i>) Major progress in tackling child undernutrition in some of the world's toughest countries is under threat as military and security funding takes precedence, a new report from aid agency World Vision warns.http://www.eurekalert.org/pub_releases/2013-07/wv-ctg071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/wv-ctg071713.php(<i>University of Texas Medical Branch at Galveston</i>) The ubiquity of the endocrine-disrupting chemical bisphenol A led researchers to ask what it might be doing in publicly supplied, chlorinated drinking water. The answer: Chlorinated BPA has different, but no less profound effects on cell-signaling networks than unmodified BPA.http://www.eurekalert.org/pub_releases/2013-07/uotm-bc071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/uotm-bc071713.php(<i>Washington University in St. Louis</i>) With the help of modern genetic technology and the resources of the International Rice GeneBank, which contains more than 112,000 different types of rice, evolutionary biologist Kenneth Olsen has been able to look back in time at the double domestication of rice (in Asia and in Africa) and its double "de-domestication" to form two weedy strains. Olsen predicts the introduction of pesticide-resistant rice will drive ever faster adaptation in weedy rice.http://www.eurekalert.org/pub_releases/2013-07/wuis-hrt071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/wuis-hrt071713.php(<i>American Friends of Tel Aviv University</i>) Dr. Tal Dvir of Tel Aviv University has integrated cardiac cells with nanofibers made of real gold particles to create functional engineered cardiac tissues. With the gold particles, these tissues contract much faster and stronger as a whole, he reports, making them more viable for transplants and post-heart-attack therapies.http://www.eurekalert.org/pub_releases/2013-07/afot-aho071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/afot-aho071713.php(<i>Kansas State University</i>) Kansas State University researchers are defeating persistent bacteria known for causing infections in hospitals.

The compound, known as PAC-1, has so far proven safe and has promising anti-cancer effects in cell culture, in mouse models of cancer and in pet dogs with spontaneously occurring lymphomas and osteosarcomas.http://www.eurekalert.org/pub_releases/2013-07/uoia-cdt071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/uoia-cdt071713.php(<i>Technical University of Denmark</i>) In general, Danes have no reason to worry about unwanted chemical compounds in the food they put on their table -- especially if they eat a varied diet. However, a monitoring survey puts focus on certain compounds -- e.g. inorganic arsenic and acrylamide, the intake of which should be reduced due to health risk. These findings are presented in the latest report on chemical contaminants in food prepared by the National Food Institute, Technical University of Denmark.http://www.eurekalert.org/pub_releases/2013-07/tuod-dse071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/tuod-dse071713.php(<i>University of Southampton</i>) Research from the University of Southampton has shown that young adults, who are more outgoing or more emotionally stable, are happier in later life than their more introverted or less emotionally stable peers.http://www.eurekalert.org/pub_releases/2013-07/uos-opl071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/uos-opl071713.php(<i>North Carolina State University</i>) Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core.

The technique could also be used for targeted drug delivery to cancer cells.http://www.eurekalert.org/pub_releases/2013-07/ncsu-is071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/ncsu-is071713.php(<i>European Molecular Biology Organization</i>) Predisposition to cancer and other diseases, genetic testing, infectious proteins and ubiquitin signalling -- these are some of the topics internationally renowned speakers will tackle at The EMBO Meeting 2013 to be held in Amsterdam, the Netherlands, from 21-24 September 2013.http://www.eurekalert.org/pub_releases/2013-07/embo-aga071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/embo-aga071713.php(<i>University of Bonn</i>) Scientists at Bonn University Hospital and at the Max Planck Institute for neurological research in Cologne have developed a method with which the chances of success of a surgical procedure for temporal lobe epilepsy can be accurately predicted. The rate of accurate predictions is more than 90%. The results are now being presented in the scientific journal "NeuroImage: Clinical."http://www.eurekalert.org/pub_releases/2013-07/uob-apf071713.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/uob-apf071713.php(<i>Springer</i>) Our contemporary understanding of the human heart and its workings is at the cutting edge of modern medical and biological research.

But surprisingly, the cancer survivors fare better psychologically and report a better quality of life than the women without cancer and have about the same levels of sexual activity and function.http://www.eurekalert.org/pub_releases/2013-07/tnam-csh071613.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/tnam-csh071613.php(<i>Scripps Research Institute</i>) An international team led by scientists at The Scripps Research Institute has determined and analyzed the three-dimensional atomic structure of the human glucagon receptor. The receptor, found mainly on liver and kidney cells, helps regulate glucose levels in the bloodstream and is the target of potential therapeutic agents for type 2 diabetes.http://www.eurekalert.org/pub_releases/2013-07/sri-sri071613.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/sri-sri071613.php(<i>Massachusetts Institute of Technology</i>) A team led by MIT researchers has now developed a way to grow liver tissue that can support the liver stage of the life cycle of the two most common species of malaria, Plasmodium falciparum and Plasmodium vivax.http://www.eurekalert.org/pub_releases/2013-07/miot-nwt071613.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/miot-nwt071613.php(<i>University of Massachusetts Medical School</i>) Scientists at the University of Massachusetts Medical School are the first to establish that a naturally occurring X chromosome "off switch" can be rerouted to neutralize the extra chromosome responsible for trisomy 21, also known as Down syndrome, a genetic disorder characterized by cognitive impairment. The discovery provides the first evidence that the underlying genetic defect responsible for Down syndrome can be suppressed in cells in culture.http://www.eurekalert.org/pub_releases/2013-07/uomm-uss071513.php Wed, 17 Jul 2013 00:00:00 EDThttp://www.eurekalert.org/pub_releases/2013-07/uomm-uss071513.php(<i>Bert L. and N.
