Dietary and lifestyle recommendations for patients at risk of macular degeneration
(Dove Medical Press) Age-related macular degeneration (AMD) is a major cause of severe visual impairment in older populations and is characterized by progressive destruction of the retinal pigment epithelial cells and photoreceptors due to low-grade inflammation, ischemia and oxidative stress. Studies show evidence that carotenoids and antioxidants derived either from the diet or from supplements may significantly reduce the risk of visual loss in these patients.

Existing drugs could benefit patients with bone cancer, genetic study suggests
(Wellcome Trust Sanger Institute) A subgroup of patients with osteosarcoma -- a form of bone cancer -- could be helped by an existing drug, suggest scientists from the Wellcome Trust Sanger Institute and their collaborators. In the largest genetic sequencing study of osteosarcoma to date, scientists discovered that 10 percent of patients with a genetic mutation in particular growth factor signalling genes may benefit from existing drugs, known as IGF1R inhibitors.

Seafood poisoning bug thwarts a key host defense by attacking the cell's cytoskeleton
(UT Southwestern Medical Center) The leading cause of acute gastroenteritis linked to eating raw seafood disarms a key host defense system in a novel way: It paralyzes a cell's skeleton, or cytoskeleton.

Bacterial organizational complexities revealed
(Michigan State University) For the first time, scientists have visualized the fine details of bacterial microcompartment shells -- the organisms' submicroscopic nanoreactors, which are comprised completely of protein.

Research suggests sexual appeals in ads don't sell brands, products
(University of Illinois at Urbana-Champaign) Ads with sexual appeals are more likely to be remembered but don't sell the brand or product, according to a meta-analysis of nearly 80 advertising studies, published online this week by the International Journal of Advertising. Researchers found no positive effect on study participants' ability to remember the brands featured in such ads or on their intention to buy the product. The research was led by University of Illinois advertising professor John Wirtz.

Mouse study suggests how hearing a warning sound turns into fearing it over time
(Emory Health Sciences) An adult mouse model reveals that changes in lattice-like structures in the brain known as perineuronal nets are necessary to 'capture' an auditory fear association and 'haul' it in as a longer-term memory.

A rising star
(University of California - Santa Barbara) It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.

How do genes get new jobs? Wasp venom offers new insights
(University of Rochester) In a study published in Current Biology on June 22, the lab of Professor John Werren at the University of Rochester describes how four closely related species of parasitic wasps change their venoms rapidly in order to adapt to new hosts, and proposes that co-option of single copy genes may be a common but relatively understudied mechanism of evolution for new gene functions, particularly under conditions of rapid evolutionary change.

New biomarker assay detects neuroblastoma with greater sensitivity
(Children's Hospital Los Angeles) Investigators at The Saban Research Institute of Children's Hospital Los Angeles have developed and tested a new biomarker assay for quantifying disease and detecting the presence of neuroblastoma even when standard evaluations yield negative results for the disease. Researchers provide the first systematic comparison of standard imaging evaluations versus the new assay that screens for five different neuroblastoma-associated genes and determine that the new assay improves disease assessment and provides prediction of disease progression.

Crohn's disease, a type of inflammatory bowel syndrome, causes debilitating intestinal swelling, cramping, and diarrhea. The disease affects half a million people in the United States, but its cause is yet unclear.

How eggs got their shapes
(Harvard John A. Paulson School of Engineering and Applied Sciences) The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery. Now, an international team of scientists took a quantitative approach to that question and found that adaptations for flight may have been critical drivers of egg-shape variation in birds.
