"It may seem the stuff of gothic horror novels, but transfusions of young blood could reverse the ageing process and even cure Alzheimer's Disease, scientists believe." -- This the lead item in an article by Sarah Knapton in London's Daily Telegraph. (I used the spelling 'ageing' there, as such is the British way.)
By the way, I misspelled Sarah Knapton's name in a previous version of this post. Sorry.
Now, before going on, let me say that the experiments so far have only been done on mice, not humans.
Also, these experiments havebeen done, not in a spooky castle in Transylvania, but rather at Harvard and Stanford. (Does that make the idea less spooky?)
The research, primarily reported in the journal Science, involved eight blood transfusions over a three-week period.
Now what they are doing with this finding in the (fictional) Hauenfelder Clinic in the remote mounntains of a certain Eastern European dictatorship I have no idea. (FYI: that Hauenfelder Clinic is the setting for my science technothriller, A REMEDY FOR DEATH. Not to worry, this is not a plot spoiler: I can tell you they don't use Vampire Therapy there . . . at least not yet! But they do lots of other thing that push the limits of medical ethics under the guise of questing for eternal youth and human immortality for the chosen few! The Hauenfelder Clinic is, one might say, a Jurassic Park for rich old guys who want to stick around . . . forever.)
