Scientists discover infinite decay and rebirth in quantum particles
O.o!
A team of scientists recently determined certain quantum particles can regenerate after they’ve decayed. This has grand implications for the future of humanity, quantum computing, and intergalactic graffiti.
Theoretical physicists from the Technical University of Munich and the Max Planck Institute conducted simulation experiments to determine that certain quasiparticles are essentially immortal. Per the second law of thermodynamics nothing lasts forever, but these quantum particle fields can reassemble themselves after decaying – just like the phoenix from Greek mythology.
Rejuvenation Roundup July 2019
Last month was arguably the busiest of all for everybody on the LEAF team, given that our second NYC conference was taking place—and, by the way, it was a great success! Today, we’re offering a detailed account of the conference as well as all that has been going on with us in July, including, of course, a recap of the latest news from the aging research and rejuvenation community.
LEAF News
Keith Comito at Ending Age-Related Diseases 2019
As promised, we’re releasing videos from Ending Age-Related Diseases 2019, our highly successful two-day conference that featured talks from leading researchers and investors, bringing them together to discuss the future of aging and rejuvenation biotechnology.
To open the proceedings, our president, Keith Comito, welcomed attendees, introduced the event’s speakers and sponsors, discussed the staff, goals, and projects of LEAF, talked about the advances in rejuvenation biotechnology, and brought forward many more topics in the world of healthy longevity.
Years and Years’ transhumanist character Bethany shows the conundrum of merging human and machine
In the premiere of the HBO/BBC miniseries Years and Years, two parents are worried. Their teenage daughter Bethany has been hiding behind a 3D animated emoji mask and has scheduled a talk with them. Trying to figure out what they’re up against, they sneak a peek at her internet searches. When they discover that she’s been searching for information about being trans, they’re relieved; they can handle a transgender child.
Except when it comes time for their talk, Bethany tells her parents she’s transhuman and that she wants to “live forever as information.” The show represents transhumanist technology and aspirations, many of which revolve around upgrading and digitizing the human body, as a movement that will bring positive, negative, and downright confusing implications, ultimately changing the human race. The real question is what exactly that means. Humans opened the Pandora’s box of merging technology and biology a long time ago, and we’re now speeding head-on into the consequences, despite not knowing what humanity will become.
Bethany’s “coming out” scene hinges on the fact that the changes she desires are far more dangerous—and, for her parents, far more difficult to stomach—than gender reassignment. Bethany’s excitement at escaping the mortal coil brims with typical teenage naïveté: “Transhumans are not male or female, but better,” she tells her parents. For Bethany, that means no longer being human. “I will be data!” she enthuses.

The journal club hosted by Dr. Oliver Medvedik returns for July and takes a look at the new SIRT6 evolutionary biology paper by Dr. Vera Gorbunova and collaborators
The journal club hosted by Dr. Oliver Medvedik returns for July and takes a look at the new SIRT6 evolutionary biology paper by Dr. Vera Gorbunova and collaborators, showing a relationship between enhanced SIRT6 function and longevity.
Abstract DNA repair has been hypothesized to be a longevity determinant, but the evidence for it is based largely on accelerated aging phenotypes of DNA repair mutants. Here, using a panel of 18 rodent species with diverse lifespans, we show that more robust DNA double-strand break (DSB) repair, but not nucleotide excision repair (NER), coevolves with longevity. Evolution of NER, unlike DSB, is shaped primarily by sunlight exposure. We further show that the capacity of the SIRT6 protein to promote DSB repair accounts for a major part of the variation in DSB repair efficacy between short- and long-lived species. We dissected the molecular differences between a weak (mouse) and a strong (beaver) SIRT6 protein and identified five amino acid residues that are fully responsible for their differential activities. Our findings demonstrate that DSB repair and SIRT6 have been optimized during the evolution of longevity, which provides new targets for anti-aging interventions.

Celebrating Our Second Conference
Ending Age-Related Diseases 2019 is over, and the dust is starting to settle after what can only be described as a hugely successful event for our organization. This was our second year of running a conference, and once more, we focused on the research and investment areas of rejuvenation biotechnology.
Totally sold out
This year, our venue at the Frederick P. Rose Auditorium at the Cooper Union in New York City was so popular that we totally sold out of tickets this year and had to turn people away! Our advice for next year is definitely to book early to avoid disappointment and take advantage of the lower prices that early booking offers.
