Snakebites can be deadly, but their poisons could be a lifesaver.

Eastern green mamba

Don’t be fooled by its lack of flashy red stripes or other visual warnings: its bites are highly poisonous. While you would want to avoid venomous snakes like the green mamba out in the wild, they are a treasure trove for some medical researchers. Continue reading –>

Think heart failure is incurable? Think again. Regenerative medicine could restore an injured heart – just by an injection to the heart.

Regenerative medicine is an increasingly popular field in the health sciences. Whereas traditional regenerative medicine looked at embryonic stem cells, more and more researchers are investigating adult pluripotent stem cells (stem cells deriving from adult cells). One of the advantages of using adult pluripotent stem cells is that complications arising from rejection after transplant can be avoided if a person’s own cells are used. Furthermore, some researchers are interested in reprogramming adult cells directly into another cell type without the cells having to go through stem cell stage; this prevents the unwanted possibility of stem cells forming into tumors at the site of transplant.
