Man Modifies His Own Genes

ProPublica has been documenting the many ways health care dollars are being wasted. We’ve shown how hospitals throw out brand new supplies, nursing homes flush tons of unexpired medication and drug companies concoct costly combinations of cheap medication. Recently we described how arbitrary drug expiration dates cause us to toss safe and potent medicine.
Often, large swaths of the medical and pharmaceutical communities know about this waste — even about solutions to it — but do nothing. Those who end up paying the bill, in one way or another, are consumers.
The makers of cancer drugs also make vials with too much medication for many patients. The excess drugs are tossed in the trash — another reason health care costs are so high.

Can the process of aging be delayed or even reversed? Research led by specially appointed Professor Jun-Ichi Hayashi from the University of Tsukuba in Japan has shown that, in human cell lines at least, it can. They also found that the regulation of two genes involved with the production of glycine, the smallest and simplest amino acid, is partly responsible for some of the characteristics of aging.

Last year, Dr. Sergio Canavero created quite the ruckus (to put it mildly) when he vowed to be the first person to transplant a human head onto a deceased donor’s body. Yes, he is planning on attempting the world’s first human head transplant (or body transplant, depending on how you look at it).
In fact, it has been about a year since his initial proclamation, and the Italian neurosurgeon still stands firm on his declaration, despite claims from other experts that it is nothing but a PR Stunt (at best) or a hoax. Some have even hypothesized it’s all just a plot meant to promote Metal Gear Solid.

LEF has access to blood tests from its customers who take the product. That means data should be available in less than a year. If it works, we can expect other DNN-developed geroprotectors.
In 2011, scientists made one of the most important discoveries in the history of AI development. They found that graphics processing units (GPUs) are far better at simulating biological learning than central processing units (CPUs).

Why our metabolism slows down as we age and the diseases it contributes to.
Researchers discover reasons for our age-related metabolic slowdown and show that metabolic changes lead to disease and aging.

If scientists could precisely regulate gene expression, they could turn off the genes responsible for illness and disease and turn on those that enhance health and the immune system.
“This is why controlling gene expression is so fundamental,” said Northwestern University’s Julius Lucks. “Once you get a good handle on it, you can do anything.”
For Lucks, having a “good” handle on gene expression might be an understatement. He and his team have developed a powerful and versatile tool that achieves gene activation thousands of times better than nature.

The benefits of rejuvenation biotechnology to end age-related diseases could go beyond just the individual.
As I wrote in a different article, rejuvenation biotechnology promises a range of benefits for individuals. Lest anyone thinks that’s all rejuvenation has to offer, I reckon it’s worth discussing other ways that this technology would benefit larger groups of people—namely, your friends and family. If you are rejuvenated, that’s all good for you, but is there anything good coming out of it for your dear ones? Oh, yes.
Two burdens relieved with a single shot
The ill health of old age is a formidable sword of Damocles looming over us all, and when it falls down, it typically does not hit just us; the elderly are certainly the primary victims, but their family are collateral casualties. When people lose their health and independence to aging, their families have to go through the pain of seeing their loved ones becoming more and more fragile, sick, dependent, perhaps even demented. Adding insult to injury, the troubles caused by aging don’t stop here, because a sick and dependent person needs looking after. Thus, the family of an elderly person needs to step in themselves to take care of their relative; if this is not possible, a nursing home is likely going to be the only option left.
