Ghost Heart
In late 2005, cardiac researcher Doris Taylor revived the dead. She rinsed rat hearts with detergent until the cells washed away and all that remained was a skeleton of tissue translucent as wax paper—a ghost heart, as Taylor calls it. She injected the scaffold with fresh heart cells from newborn rats. Then she waited.

Meanwhile this procedure is just using the existing heart. This procedure wud probably get rid the probability of organ rejection after the transplant and most likely be able to aid in the post-transplant treatment.

The Stinkiest Fuel on Earth
Will Brinton, the founder of Woods End Laboratories, a bioenergy consultancy, predicts a future without landfills. Instead we’ll use table scraps and sewage to power our homes. Just dump the waste into a household digester, and bacteria will break it down and release the natural gas methane. Farms could sell their copious poop-based energy supplies back to the grid. But how much energy do animals yield? We ran the numbers and found that you might want to consider a pet elephant.
9.24.2008 at 05:40pm - Comment by xharmthe biogas from the poop was produced in an enclosed tank,bioreactor.Bio-methanation (an aerobic process of organic materials decomposition) occurs in there which then produced carbon dioxide n methane as the final product of the biochemical process. This renewable source of energy had been used in ages by the rural indian comity.
