People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

In the Future, Spider Silk May Help Grow Your Replacement Heart

RATE THIS! +45
Posted in Science on 12th Apr, 2015 07:51 PM by AlexMuller

There’s been a lot of talk lately about how spider silk is this crazy wonder material that may soon find its way into everything from electronics to ultra-strong fabrics. Now, there’s another reason to be excited about spider silk: doctors might one day use the stuff to grow you a new heart.

 
Growing new organs and tissues outside the body is the bleeding edge of biomedical research. Just imagine: if doctors could grow replacement hearts or kidneys from a patient’s own stem cells, that patient would no longer have to face the agonising prospect of waiting to find a suitable donor.
 
The risk of organ rejection would become nil. But there’s a lot of R&D to be done before we get there. One initial challenge has been finding a scaffold material to grow organ tissues on, something that’s non-toxic, will not impede cell growth, and will not, itself, be rejected by the body. That, it turns out, is a pretty tall order.
 
But, as described in a study published recently in PLOS ONE, genetically engineered fibers of spidroin, the protein that builds cobweb strands, might just fit the bill when it comes to human heart tissue. Spidroin fibers have already proven themselves a useful substrate for growing tendons and cartilages.
 
Researchers at the Moscow Institute for Physics and Technology decided to see whether spidroin grown in the lab via genetically modified yeast cells can also be used to grow cardiomycetes, the cells that form heart tissue.

Compatible donors are a big limitation in organ transplantation and lives of millions can be saved by overcoming such obstacles - great work Reply
