'Vortex lattices' may help explain material defects
12-22-2006 · EurekAlert!By combining two cutting-edge laboratory creations -- optical lattices and atoms in a Bose-Einstein condensate spinning in a trap -- physicists from NIST and the University of Colorado have developed a method of visualizing defects in rotating patterns, a new method that could be used to simulate why and how defects arise in superconductors and other important materials that are difficult to study directly.

- Scientists reveal secrets of Homer's Cyclops to help people with Holoprosencephaly
01-17-2007 · EurekAlert!
Scientists from Cleveland, Ohio, and Paris, France, reached an important milestone in understanding a molecular cause of a rare, but serious birth defect, Holoprosencephaly. In this February's FASEB Journal, researchers explain why and how some fetal brains fail to develop two lobes, as well as why and how the related skull and facial defects occur. Information from this study will enable researchers to pursue better approaches toward detecting, preventing, and treating this serious disorder.

- Technology helps predict outcome of pediatric heart surgery
11-28-2006 · EurekAlert!
Georgia Tech and Emory University researchers have developed an innovative new technology that will help pediatric cardiac surgeons design and test a customized surgical procedure before they ever pick up a scalpel. With a better understanding of each child's unique heart defect, surgeons could greatly improve the likelihood that children with complex defects requiring multiple surgeries over a period of several years could have smoother recoveries and an improved quality of life after their operations.

- SSRI antidepressants do not pose major birth defect risk
06-27-2007 · EurekAlert!
Researchers from Boston University's Slone Epidemiology Center have found that certain selective serotonin reuptake inhibitors antidepressants do not appear to increase the risk for most kinds of birth defects. The findings, to be published in the June 28 issue of the New England Journal of Medicine, suggest that individual SSRIs may increase the risk for some specific defects, but these are rare and the absolute risks are small.

- University of Pennsylvania engineers discover natural 'workbench' for nanoscale construction
07-17-2007 · EurekAlert!
Engineers at the University of Pennsylvania have taken a step toward simplifying the creation of nanostructures by identifying the first inorganic material to phase separate with near-perfect order at the nanometer scale. The finding provides an atomically tuneable nanocomposite "workbench" that is cheap and easy to produce and provides a super-lattice foundation potentially suitable for building nanostructures.

- Monell researchers find metabolic defect in liver that can lead to obesity
07-24-2007 · EurekAlert!
Researchers at the Monell Center have identified a genetically-transmitted metabolic defect that can lead to obesity. The defect involves decreased production of liver enzymes needed to burn fat and may help to explain why some people become obese while others remain thin. The findings could open the door to the development of new obesity drugs.

- Severe heart defect likely caused by genetic factors
10-10-2007 · EurekAlert!
Hypoplastic Left Heart Syndrome, a severe cardiovascular malformation that is difficult to treat and often lethal, is caused primarily by genetic factors, according to a new study by researchers at Cincinnati Children's Hospital Medical Center. Families having children with HLHS carry a significant recurrence risk of HLHS or related heart defects.

- Gene involved in common birth defect also regulates skin biology
10-15-2006 · EurekAlert!
Following up on an earlier discovery that a gene called IRF6 is involved in the common birth defect cleft lip and palate, University of Iowa researchers and their colleagues have identified the function of the gene. Their latest findings, published online Oct. 15 in Nature Genetics, reveal an unexpected role for IRF6 in the growth and development of skin cells, a discovery that may have implications for wound healing and cancer research.
