"It's life and life only"–B. Dylan

This team published two papers in Nature stating that they were able to take mature, adult, mouse cells, and subject them to stress “almost to the point of death”, by exposing them to various events including trauma, low oxygen levels and acidic environments. After a few days they would check on the cells and by putting the adult cells through this they were able to create embryonic-type stem cells. These stimulus triggered acquisition of pluripotency or STAP cells were created without the use of embryonic cells and would offer a new cheap alternative to current methods used to create stem cells.

If these cells could be used in humans, it would represent a game changer in the type of cell therapies that could be done, with the patients cells as the starting material. If only it were that easy. So now what everyone supposed to think. ... Welcome to Nualgi.com ... File:Quartz, Tibet.jpg. Komen Surveying Supporters On Next Moves, Image. Has Susan G.

Komen for the Cure kicked up another hornet’s nest? If the reaction on Twitter and Facebook is any indication, you might say yes. After what seemed like a quiet couple of weeks on social media for Komen, some users again were lambasting the Irving, Texas-based organization on Friday after The Huffington Post reported that Komen had hired a consulting firm to survey donors in the wake of the controversy over funding to Planned Parenthood. The survey asks donors whether the Komen still owes them an apology, followed by a list of potential apologies, and potential new spokespeople.

Among the 20 spokespeople listed are former elected officials, celebrities (some who have or had breast cancer such as Guiliana Rancic and Melissa Etheridge), medical professionals and Komen officials. It’s not uncommon for organizations to test platforms and messaging through surveys, but it is unusual that they become public, said Rebecca Devine, co-founder and principal of Philadelphia, Pa. Quartz. Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar.

Quartz

It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2. There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings. Etymology[edit] The word "quartz" is derived from the German word "Quarz" and its Middle High German ancestor "twarc", which probably originated in Slavic (cf.
