Apparently, Peter Thiel Is Very, Very Interested in Young People's Blood

According to the article, ...

More than anything, Peter Thiel, the billionaire technology investor and Donald Trump supporter, wants to find a way to escape death. ... if there's one thing that really excites Thiel, it's the prospect of having younger people's blood transfused into his own veins. ... according to Thiel, it's a potential biological Fountain of Youth - the closest thing science has discovered to an anti-ageing panacea.

[...] After decades languishing on the fringes, it's recently started getting attention from mainstream researchers, with multiple clinical trials underway in humans in the U.S. and even more advanced studies in China and Korea.

[...] In Monterey, California, about 120 miles from San Francisco, a company called Ambrosia recently commenced one of the trials. Titled "Young Donor Plasma Transfusion and Age-Related Biomarkers," it has a simple protocol: Healthy participants aged 35 and older get a transfusion of blood plasma from donors under 25, and researchers monitor their blood over the next two years for molecular indicators of health and ageing. The study is patient-funded; participants, who range in age from late 30s through 80s, must pay $8,000 to take part, and live in or travel to Monterey for treatments and follow-up assessments.

I thought I would bring this development to the attention of the Soylent News community. I also have a question. The article claims that the practice is known as parabiosis. But Wikipedia says "parabiosis is a class of techniques in which two living organisms are joined together surgically and develop single, shared physiological systems, such as a shared circulatory system." This definition seems to include the relevant 1950s rat experiments. But I believe it does not cover the Monterey experiment, nor the kinds of human treatment that Thiel and others are seeking. Am I right about this? And if so, is there better word to use?

Also, feel free to comment any fictional examples you know of. Did Montgomery Burns ever partake, for example?

Want to stay/get younger? Inject plasma from a younger person...

Now a startup has launched a "clinical trial" to test the antiaging benefits of such treatment...but it's pay-per-view. Writing in Science today, Jocelyn Kaiser reports on the ethical, and other, aspects of this project. From her article, "Young blood antiaging trial raises questions":

[...] The company, Ambrosia in Monterey, California, plans to charge participants $8000 for lab tests and a one-time treatment with young plasma. The volunteers don't have to be sick or even particularly aged--the trial is open to anyone 35 and older. Karmazin notes that the study passed ethical review and argues that it's not that unusual to charge people to participate in clinical trials.

To some ethicists and researchers, however, the trial raises red flags, both for its cost to participants and for a design that they say is unlikely to deliver much science. "There's just no clinical evidence [that the treatment will be beneficial], and you're basically abusing people's trust and the public excitement around this," says neuroscientist Tony Wyss-Coray of Stanford University in Palo Alto, California, who led the 2014 young plasma study in mice. [In which injecting old mice with the plasma portion of blood from young mice seemed to improve the elderly rodents' memory and ability to learn.]

[...]

To bioethicist Leigh Turner at the University of Minnesota, Twin Cities, the study brings to mind a growing number of scientifically dubious trials registered in ClinicalTrials.gov by private, for-profit stem cell clinics. The presence of such trials in the database confers "undeserved legitimacy," he says.

The scientific design of the trial is drawing concerns as well. "I don't see how it will be in any way informative or convincing," says aging biologist Matt Kaeberlein of the University of Washington, Seattle. The participants won't necessarily be elderly, making it hard to see any effects, and there are no well-accepted biomarkers of aging in blood, he says. "If you're interested in science," Wyss-Coray adds, why doesn't such a large trial include a placebo arm? Karmazin says he can't expect people to pay knowing they may get a placebo. With physiological measurements taken before and after treatment, each person will serve as their own control, he explains.
