Stem cells obtained from urine could allow us to regrow lost teeth, according to scientists.

In mice, a new system of tissue culture has allowed researchers to grow the cells into tiny structures resembling teeth, and they hope one day the technology could permit them to build the real thing in human patients.

The stem cells are generated from urine, based on previous studies which have shown discarded cells in human waste can be coaxed into becoming pluripotent stem cells (iPSCs).

These can then themselves generate many different cell types, including neurons and heart muscle cells.

But researchers had yet to generate solid organs or tissues from iPSCs – until now, reported Cell Regeneration Journal.

Dr Duanqing Pei, of the Chinese Academy of Sciences, created the tooth-like structures by forcing iPSCs to mimic two different cell types; epithelial cells, which give rise to enamel, and mesenchymal cells, which give…

The Daily Post

Recently, photographer Wenjie Zhang introduced us to the fundamentals of light. Let’s continue our journey through the Photography 101 series and move on to composition. For the next few installments, photographer (and active Daily Post participant) Jeff Sinon takes the reins. Here in part one, he introduces some of the “rules” and elements of composition, and in part two, he’ll offer insights and tips on how to find the best shot.

Jeff illustrates his points with stunning landscapes and nature scenes he’s captured, taken mainly with his Canon 7D, but you can apply his techniques to your own images, no matter your camera or subject matter. Let’s go!

The WordPress.com Blog

iTheme2 was originally conceived as a tech blog theme, paying homage to the sleek design of Apple websites. The three blogs we showcase here are proof of its remarkable versatility: not one of them covers technology.

Whether it’s the natural splendors on view on Yosemite Park Blog, the romance-heavy book reviews on Have Book Will Reador the cutting-edge beats swirling through webzine Electronic Rumors, these blogs are brimming each with their own quirky personality. All three harness the nifty features built into iTheme2 to their specific needs. Time to compare, contrast, and admire.
