In 1824, John James Audubon (1785-1851), the eminent American artist, created a drawing of a running grouse for use in the design for a New Jersey bank note. Although the artist mentions the drawing and the resulting engraved paper money in two separate diary entries, no one has ever been able to locate or identify such an illustration. Until now.

Astronomers have imaged a very young brown dwarf, or failed star, in a tight orbit around a young nearby sun-like star. The discovery is expected to shed light on the early stages of solar system formation.

Cell-of-origin for human prostate cancer identified for first time

admin — Fri, 30 Jul 2010 02:43:28 +0000

Scientists have identified for the first time a cell-of-origin for human prostate cancer, a discovery that could result in better predictive and diagnostics tools and the development of new and more effective targeted treatments for the disease.

Fluorescent biosensor to aid in drug development

admin — Fri, 30 Jul 2010 02:43:27 +0000

Scientists have developed a new fluorescent biosensor that could aid in the development of an important class of drugs that target a crucial class of proteins called G protein-coupled receptors (GPCRs). GPCRs are popular drug targets because of the pivotal role they play in cells’ communication circuits responsible for regulating functions critical to health, including circuits involved in heart and lung function, mood, cognition and memory, digestion and the inflammatory response.

Vascular-targeted photodynamic therapy for localized prostate cancer

admin — Fri, 30 Jul 2010 02:43:27 +0000

NYU Langone Medical Center has begun a clinical trial offering vascular-targeted photodynamic therapy to patients with localized prostate cancer. This novel, minimally invasive procedure uses a light-activated drug to deliver light energy waves by way of laser fibers in order to destroy prostate cancer cells.
