Fetal exposure to PVC plastic chemical linked to obesity in offspring
Jan. 15, 2013 Exposing pregnant mice to low doses of the chemical tributyltin — which is used in marine hull paint and PVC plastic — can lead to obesity for multiple generations without subsequent exposure, a UC Irvine study has found.
3-D mapping of lipid orientation in biological tissues such as skin
Jan. 15, 2013 A non-invasive method that makes it possible to observe in situ how assemblies of lipids are oriented in biological tissues, and which does not require any labeling or preparation, has been developed by physicists from the Laboratoire d’Optique et Biosciences (CNRS / Inserm / École Polytechnique). This work, published on the 14 January 2013 in the online journal Physical Review X , should enable the detection and characterization of certain pathologies associated with molecular disorders in the skin or in the nervous tissue.
Designer bacteria may lead to better vaccines
Jan. 15, 2013 Researchers at The University of Texas at Austin have developed a menu of 61 new strains of genetically engineered bacteria that may improve the efficacy of vaccines for diseases such as flu, pertussis, cholera and HPV. The strains of E.

Some children lose autism diagnosis: Small group with confirmed autism now on par with mainstream peers
Jan. 15, 2013 Some children who are accurately diagnosed in early childhood with autism lose the symptoms and the diagnosis as they grow older, a study supported by the National Institutes of Health has confirmed
Flexible, nanoscale ‘bed of nails’ created for possible drug delivery
Jan. 15, 2013 Researchers at North Carolina State University have come up with a technique to embed needle-like carbon nanofibers in an elastic membrane, creating a flexible “bed of nails” on the nanoscale that opens the door to development of new drug-delivery systems. The research community is interested in finding new ways to deliver precise doses of drugs to specific targets, such as regions of the brain.
Drug overdose now the leading cause of death among homeless adults in Boston
Jan. 14, 2013 Drug overdose was the leading cause of death among homeless adults in Boston from 2003 to 2008 and accounted for one-third of deaths among those ages 25 to 44. A study by investigators from Massachusetts General Hospital (MGH) and the Boston Health Care for the Homeless Program (BHCHP) compared rates and causes of death among those served by BHCHP with data from a similar 1997 study and found that, while drug overdose had replaced HIV as the leading cause of death, overall mortality rates had not changed.
Surprising twist to protein misfolding discovered
Jan. 14, 2013 An effort to develop software that unravels the complexities of how proteins fold is paying dividends in new findings on how they misfold, according to researchers at Rice University. The study published this week in the Proceedings of the National Academy of Sciences by chemist Peter Wolynes and his team at Rice’s BioScience Research Collaborative should be of particular interest to those who probe the roots of degenerative diseases associated with the aggregation of amyloid fibers in the body
