Human Eggs Can Develop From Ovarian Surface Cells In Vitro
Research has shown for the first time that human eggs may develop directly from cultured ovarian surface epithelium (OSE) cells derived from adult human ovaries. Oocytes derived from the culture of OSE cells developed in vitro into mature eggs suitable for fertilization and development into an embryo. These findings, published today in the Open Access journal Reproductive Biology and Endocrinolog...Hopkins scientists uncover 'tags' that force proteins to cell surface
Discovery likely to streamline drug and vaccine development Johns Hopkins scientists have discovered internal "shipping labels" that allow -- and perhaps force -- hundreds if not thousands of proteins to get to the surface of cells and stay there. Two natural proteins that use one of these "tags" are the ion channel that lets heart cells contract on cue, and the docking point that allows...Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic according to a new study to be published in the Sept. 22, 2005, issue of Science Express. The resulting atmospheric heating in the region of northern Alaska is equivalent to...Shampoo detergent added to paint makes surfaces self-sterilizing
Adding a common ingredient in shampoo to paints and varnishes can create self-sanitizing coatings for frequently touched surfaces in public buildings that continue killing germs for months, according to research conducted by a multi-state consortium of high school students and retirees. Working through the website science-projects.com, 10 students from New York, Texas and Virginia joined t...Bacteria can survive for weeks on hospital surfaces
A major cause of hospital-acquired infections can persist for days and even weeks on environmental surfaces found in healthcare settings, including bed linens, computer keyboard covers and acrylic fingernails, according to research presented today at the 105th General Meeting of the American Society for Microbiology. Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of ho...BD Falcon Roller Bottle, smooth surface from BD Biosciences - Discovery Labware

Lunar forces may be causing the surface of the earth to slip westward, according to a study by Italian and American scientists, which has been published by the Bulletin of the Geological Society of America.// Carlo Doglioni of Rome's La Sapienza University and his team of Italian and US scientists argue that the westward motion is due to the tidal attraction of the moon. The earth's...Controversy Over The Fee Structure In Private Medical Colleges Surfaces Yet Again
The controversy around the fee structure in private medical & paramedical colleges was hoped to end in Karnataka with the governor of the state T.N. Chaturvedi having signed the CET bill//. But it has only flared up a conflict between the management of the private medical colleges and the state government has surfaced yet again. Caught in the crossfire are the students who are now looking at the...Banking (T)issues : cloning issue surfaces
Recently, a survey was conducted in Australia to study the attitudes of people towards “tissue banking”. The results show that a number of Australians are concerned about the// outcome of storage of tissue samples at hospitals. Researchers from the University of Sydney found that ,most people were wary about biopsy tissue being stashed away by hospitals. Many fear that these tissues co...Meningitis C Surfaces in Toronto:Public Alerted
