Leave it to Berlin to breed the coolest of tech-related gatherings. At this interdisciplinary ‘unconference’, industry leaders and tech enthusiasts rubbed shoulders as they sipped chia seed smoothies among the sun-kissed gardens of an abandoned carpet factory.
While exploring which biological processes might predict successful in centenarians, a team from Newcastle and Tokyo have identified two prominent factors that facilitate health longevity — low level inflammation and telomere length.
“Centenarians and supercentenarians are different — put simply, they age slower. They can ward off diseases for much longer than the general population.”
After measuring a number of health markers in 1,554 people including: those over 105, between 100 and 105 and a group near their 100th birthday along with their offspring, these two elements emerged as consistent longevity predictors.

Scientists say they have cracked the secret of why some people live a healthy and physically independent life over the age of 100: keeping inflammation down and telomeres long.
Newcastle University’s Institute for Ageing in the U.K. and Keio University School of Medicine note that severe inflammation is part of many diseases in the old, such as diabetes or diseases attacking the bones or the body’s joints, and chronic inflammation can develop from any of them.

The Millennium Project released today its annual “2015–16 State of the Future” report, listing global trends on 28 indicators of progress and regress, new insights into 15 Global Challenges, and impacts of artificial intelligence, synthetic biology, nanotechnology and other advanced technologies on employment over the next 35 years.
“Another 2.3 billion people are expected to be added to the planet in just 35 years,” the report notes. “By 2050, new systems for food, water, energy, education, health, economics, and global governance will be needed to prevent massive and complex human and environmental disasters.”
Once again telomeres are shown to be key players in aging.
The secret to living long, healthy lives and ageing beyond 100 has finally been cracked, according to a new study.
Scientists at Newcastle University say they have identified the key to longevity and good health amongst centenarians and how they pass that gift onto their offspring.

Death still enjoys a steady paycheck, but being the Grim Reaper isn’t the cushy job that it used to be.
A newly developed vaccine against the deadly Ebola virus being trialled in Guinea is “highly effective,” the World Health Organization said Friday.
Not long ago, schoolchildren chose what they wanted to be when they grew up, and later selected the best college they could gain admission to, spent years gaining proficiency in their fields, and joined a company that had a need for their skills. Careers lasted lifetimes.
Now, by my estimates, the half-life of a career is about 10 years. I expect that it will decrease, within a decade, to five years. Advancing technologies will cause so much disruption to almost every industry that entire professions will disappear. And then, in about 15–20 years from now, we will be facing a jobless future, in which most jobs are done by machines and the cost of basic necessities such as food, energy and health care is negligible — just as the costs of cellphone communications and information are today. We will be entering an era of abundance in which we no longer have to work to have our basic needs met. And we will gain the freedom to pursue creative endeavors and do the things that we really like.

OK. In scientific terms, it is only a ‘hypothesis’ — the reverse of the ‘Disposable Soma’ theory of ageing. Here how it goes.
For the past several decades, the Disposable Soma theory of ageing has been enjoying good publicity and a lively interest from both academics and the public alike. It stands up to scientific scrutiny, makes conceptual sense and fits well within an evolutionary framework of ageing. The theory basically suggests that, due to energy resource constraints, there is a trade-off between somatic cell and germ cell repair. As a result, germ cells are being repaired effectively and so the survival of the species is assured, at a cost of individual somatic (bodily) ageing and death. To put it very simply, we are disposable, we age and die because all the effective repair mechanisms have been diverted to our germ cell DNA in order to guarantee the survival of our species.
The theory accounts for many repair pathways and mechanisms converging upon the germ cell, and also for many of those mechanisms being driven away from somatic cell repair just to ensure germ cell survival. In the past two or three years however, it is increasingly being realised that this process is not unidirectional (from soma to germ), but it is bi-directional: under certain circumstances, somatic cells may initiate damage that affects germ cells, and also that germ cells may initiate repairs that benefit somatic cells!
I can’t even begin to describe how important this bi-directionality is. Taking this in a wider and more speculative sense, it is, in fact, the basis for the cure of ageing. The discovery that germ cells can (or are forced to) relinquish their repair priorities, and that resources can then be re-allocated for somatic repairs instead, means that we may be able to avoid age-related damage (because this would be repaired with greater fidelity) and, at the same time, avoid overpopulation (as our now damaged genetic material would be unsuitable for reproduction).
