Beyond batteries: Storing power in a sheet of paper
...itors have potential as power supplies for devices implanted in the body. The team printed paper batteries without adding any electrolytes, and demonstrated that naturally occurring electrolytes in human sweat, blood, and urine can be used to activate the battery device. Its a way to power a small device su...OHSU turns mouse into factory for human liver cells
...ts for multiple generations, and each mouse can be implanted with human liver cells at least four times. Grompe estimates that each round of implantation can generate more than 20 million viable human liver cells. "We think we will have a real edge in terms of quality and availability of cells," Grompe said....Not all embryonic stem cell lines are created equal

To the best of my knowledge, until now there have been few functional studies of the neurons derived from embryonic stem cells, said Sdhof.

The adult stem cells obtained are implanted in the damaged eye and the limb is regenerated, this leading to the recovery of the corneal epithelium and, thereby, the transparency of the cornea.

... It is far worse to kill embryos after they have implanted in a womans womb, than it is to take embryos before implantation, when they are no more than a collection of cells, freeze any surplus embryos and transfer no more than one or two embryos at one time. It is best that only those with the highest impla...Cloning the male genome may help infertile men

Since this work aims at preserving the contribution of both parents to the generation of embryos, I feel that, when it is further developed and refined, it should elicit a favourable response from those involved in ethical issues, said ...Researchers use adult stem cells to create soft tissue

Because the implants can be molded into any size or shape, they could also be used for breast reconstruction. ...WPI professor to represent American Mathematical Society at exhibition on science funding
