New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction holds promise for fast and efficient electronic circuits, though engineers must contend with the fact that the interiors of such materials are effectively wasted space.

Breaking the 'stalemate' in the most common soft tissue sarcoma in children

A phase 2 clinical trial has found that combining a molecular targeted drug called temsirolimus with chemotherapy shows promise in the treatment of rhabdomyosarcoma, the most common soft tissue sarcoma in childhood.

Few people with peanut allergy tolerate peanut after stopping oral immunotherapy

Allergy to peanut, which is often severe, is one of the most common food allergies in the United States. Although previous studies have shown that peanut oral immunotherapy (OIT)—ingesting small, controlled amounts of peanut protein—can desensitize adults and children and prevent life-threatening allergic reactions, the optimal duration and dose is unknown. In a study that followed participants after OIT successfully desensitized them to peanut, discontinuing OIT or continuing OIT at a reduced dose led to a decline in its protective effects. The study, published online today in The Lancet, also found that several blood tests administered before OIT could predict the success of therapy. The Phase 2 study was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, and may inform who may benefit from peanut OIT and what changes in this experimental treatment should be implemented.

It takes a 'consortium': Researchers develop metabolic engineering technique

For years, scientists have explored ways to alter the cells of microorganisms in efforts to improve how a wide range of products are made—including medicines, fuels, and even beer. By tapping into the world of metabolic engineering, researchers have also developed techniques to create "smart" bacteria capable of carrying out a multitude of functions that impact processes involved in drug delivery, digestion, and even water decontamination.

Gene therapy helps functional recovery after stroke

A new gene therapy turns glial cells—abundant support cells in the brain—into neurons, repairing damage that results from stroke and significantly improving motor function in mice. A paper describing the new therapy, which uses the NeuroD1 gene, appears online in the journal Molecular Therapy. Once further developed, this NeuroD1-based gene therapy could potentially be used to treat stroke, which is a leading cause of disability in the U.S., with 800,000 new stroke patients every year.

Study finds genetic analysis can aid treatment of eosinophilic Esophagitis

Personalized medicine—where the proper medicine and proper dose are used for the individual patient—moved a step closer to reality for children suffering from eosinophilic esophagitis (EoE), an inflammation of the food pipe often caused by an allergic reaction to certain foods. The study, led by researchers from Nemours Children's Health System and published today in the Journal of Pediatric Gastroenterology & Nutrition, suggests that a simple genetic test from a saliva sample may greatly boost response rates in children with eosinophilic esophagitis who are treated with a class of medications called proton pump inhibitors (PPIs), which are commonly prescribed to treat acid-related conditions.
