Videos on Immortality

The following are some of the available videos on video sharing sites such as Youtube about the subjects of longevity and regenerative medicine. Most of these videos contain individual insights and footages from lectures and academic forums.

Researchers at a Scottish university say the technology will speed up progress towards the creation of artificial human organs.Scientists have taken a step closer to creating artificial human organs and using them for transplants after 3D printing produced clusters of stem cells. In the short term, the technique could be used to generate tissue for drug-testing currently carried out on animals.

Planarians have attracted the attention of generations of biologists. It is not hard to see why: cut a worm into two fragments and each fragment regenerates a complete organism. Cut it into 8 fragments and each individual fragment will go on to regenerate a complete animal. In this second part of the lecture, I will briefly review the rich history of planarian research, followed by a summary of the central principles of planarian regeneration that have been derived from this extensive, often fascinating body of experimental work.

It may seem premature to be discussing approaches to the effective elimination of human aging as a cause of death at a time when essentially no progress has yet been made in even postponing it. However, two aspects of human aging combine to undermine this assessment. The first is that aging is happening to us throughout our lives but only results in appreciable functional decline after four or more decades of life: this shows that we can postpone the functional decline caused by aging arbitrarily well without knowing how to prevent aging completely, but instead by increasingly thorough molecular and cellular repair. The second is that the typical rate of refinement of dramatic technological breakthroughs is rather reliable (so long as public enthusiasm for them is abundant) and is fast enough to change such technologies (be they in medicine, transport, or computing) almost beyond recognition within a natural human lifespan. In this talk I will explain, first, why (presuming adequate funding for the initial preclinical work) therapies that can add 30 healthy years to the remaining lifespan of healthy 55-year-olds may arrive within the next few decades, and, second, why those who benefit from those therapies will very probably continue to benefit from progressively improved therapies indefinitely and thus avoid debilitation or death from age-related causes at any age.

Recognizing that the root of disease is often at the nanoscale, the question arises if medical diagnosis and therapy would not also work best at the nanoscale. Patrick Hunziker from the University Hospital Basel exemplifies how nanoscience methods, materials and tools can be used to advance medicine.

Nir Barzilai, M.D., discusses the Longevity Genes Project and his quest to find ways to delay the aging process. Dr. Barzilai is director of the Institute for Aging Research at Albert Einstein College of Medicine of Yeshiva University and an attending physician at Montefiore Medical Center.

A number of neuroscientists, working today with simple model organisms, are investigating the hypothesis that chemical brain preservation may inexpensively preserve the organism's memories and mental states after death. Chemically preserved brains can be stored at room temperature in cemeteries, contract storage, even private homes.

Hank introduces us to another amazing organism - the "immortal jellyfish," Turritopsis dohrnii - and explains how it can extend its life cycle indefinitely through a process known as transdifferentiation.

Telomerase, a specialized ribonucleprotein reverse transcriptase, is important for long-term eukaryotic cell proliferation and genomic stability, because it replenishes the DNA at telomeres. Thus depending on cell type telomerase partially or completely (depending on cell type) counteracts the progressive shortening of telomeres that otherwise occurs. Telomerase is highly active in many human malignancies, and a potential target for anti-cancer approaches. Furthermore, recent collaborative studies have shown the relationship between accelerated telomere shortening and life stress and that low telomerase levels are associated with six prominent risk factors for cardiovascular disease.

What controls aging? Biochemist Cynthia Kenyon has found a simple genetic mutation that can double the lifespan of a simple worm, C. Elegans. The lessons from that discovery, and others, are pointing to how we might one day significantly extend youthful human life.

Cryonics involves the cryopreservation of humans as soon as possible after legal and clinical "death". Legal and clinical death differ importantly from biological death or true (irreversible) cessation of function. It is therefore a mistake to portray cryonics as an alternative to cremation or burial. It is true that cryopreserved people are not alive but neither are they dead. Cryonics should be seen as part of the field of life extension. Cryonics enables the transport of critically ill people through time in an unchanging state to a time when more advanced medical and repair technologies are available. Even after "longevity escape velocity" has been attained and aging has been largely tamed, cryonics will continue to be needed for people who die of accidents or diseases for which there is no cure at the time.

Research results from the UNM-UCSB Tsimane Health and Life History Project--a joint health and anthropology project aimed at understanding the impacts of ecology and evolution on the shaping of the human life course. Focus on health, growth and development, aging, economics and biodemography of small-scale populations of hunter-gatherers and horticulturalists. Also biomedical and anthropological research with medical attention among Tsimane, an indigenous forager-farming group living in central lowland Bolivia in the Beni Department.

Interview

In the third and last part of this lecture, I will introduce the model system we have developed to study animal regeneration, the planarian Schmidtea mediterranea. I will review its anatomy, and the biological attributes that make these animals extraordinarily well suited to dissect the molecular and cellular basis of regeneration. I will also discuss recent work from my laboratory aimed at identifying molecules associated with regenerative capacities.

Regeneration has fascinated philosophers and scientists since the beginning of history. The wide but uneven distribution of regenerative capacities among multicellular organisms is puzzling, and the permissive/inhibitory mechanisms regulating this attribute in animals remain a mystery. In the first part of this lecture, I will provide a general history of regeneration research from ancient Greece to the beginning of the 20th century. Key concepts will be introduced in their appropriate historical context, and many of the unanswered questions put forward by the problem of regeneration will be discussed

This holiday season give yourself the gift of good health and check out the latest breakthroughs in Russian medical science. Russia's leading cardiovascular center tests out a brand new artificial heart valve that combines the best of the biological and mechanical worlds. Dental surgery is no longer such a headache with the latest laser scalpel developed in St. Petersburg. Fancy living forever?
