Data from unique gene function studies show Rb is required for proliferation of retinal cells and development of the light-sensitive rods and gives hints for improving treatment of retinoblastoma
The finding that a tumor-suppressor protein called Rb is required for proper development of the mouse retina is a major step toward understanding why some children develop the devastating eye cancer called retinoblastoma. This discovery should eventually help scientists design a better treatment for this disease, according to investigators at St. Jude Childrens Research Hospital. An article about this research is published in the Feb. 29 issue of Nature Genetics.
The St. Jude team showed that Rb limits the proliferation of immature retinal cells so the retina develops to a normal size. The Rb protein also prompts specific cells to develop into light-sensitive cells called rods.

Researchers in the Cockrell School of Engineering at The University of Texas at Austin are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission, as described in two new research papers.
By allowing indoor occupants to more precisely control the energy and sunlight passing through a window, the new materials could significantly reduce costs for...
Argonne scientists used Mira to identify and improve a new mechanism for eliminating friction, which fed into the development of a hybrid material that exhibited superlubricity at the macroscale for the first time. Argonne Leadership Computing Facility (ALCF) researchers helped enable the groundbreaking simulations by overcoming a performance bottleneck that doubled the speed of the team's code.
While reviewing the simulation results of a promising new lubricant material, Argonne researcher Sanket Deshmukh stumbled upon a phenomenon that had never been...
