The decline of the thymus, responsible for the upkeep of our adaptive immune system, might be due to oxidative damage and insufficient antioxidant mechanisms to combat it.
What if “life in prison” could mean 100 or 200 or 400 years? Does that change the way that sentences are doled out? What happens when a person gets out of prison?
For all of you who’ve written in asking me to do an episode about longevity, this episode is for you. But instead of looking at the usual living forever stuff, we’re specifically going to talk about what happens when it gets applied to the prison system.
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.
This is an interesting story in one of Italy’s top 3 papers/sites about life extension science and millennials living beyond 100 years of age. It also features transhumanism: http://numerus.corriere.it/2015/08/06/i-millennials-camperan…ermettere/ and the English: https://translate.google.com/translate?hl=en&sl=it&u=http://…rev=search
Le tendenze della statistica ci dicono che chi oggi ha vent’anni ha ottime probabilità di arrivare ai cento in buona salute. Forse anche molto di più, se avranno successo le battaglie del Partito Transumanista che si presenta alle elezioni americane del 2016 con l’obiettivo di puntare più risorse sulla lotta all’invecchiamento. Ma come si configura un mondo di persone tanto longeve? L’allungamento della vita potrà beneficiare tutte le popolazioni o soltanto una fascia di privilegiati? Già oggi la speranza di vita nei Paesi più poveri è mediamente inferiore di 18 anni rispetto ai Paesi più ricchi e anche in Italia ci sono tre anni di differenza tra Milano e Napoli. E come si ridisegna un sistema sociale nel quale le persone vivranno venti o trent’anni più di oggi?
Un autobus rosso a forma di bara, con tanto di fiori finti sul tetto, percorre le strade degli Stati Uniti. Lo ha voluto il leader del Partito transumanista Zoltan Istvan, candidato alle elezioni presidenziali del 2016. Istvan non diventerà presidente, ma il suo messaggio non è banale: con il suo tour elettorale, vuole attirare l’attenzione sulla battaglia contro l’invecchiamento. Chiede più fondi per la ricerca e per le cure sanitarie, più carriere nelle attività tecnologiche, nell’intelligenza artificiale e nella medicina.

Eating a group of specific foods — known as the MIND diet — may slow cognitive decline among aging adults, even when the person is not at risk of developing Alzheimer’s disease, according to researchers at Rush University Medical Center.
This finding supplements a previous study by the research team, reported by KurzweiliAI in March, that found that the MIND diet may reduce a person’s risk in developing Alzheimer’s disease.
The researchers’ new study shows that older adults who followed the MIND diet more rigorously showed an equivalent of being 7.5 years younger cognitively than those who followed the diet least. Results of the study were recently published online in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
As the brain ages, it becomes less efficient at recycling and eliminating build up of waste; ‘removal vans’ fail to do the rounds, and accumulation starts to overtake removal.
“We found that people in their 30s typically take about four hours to clear half the amyloid beta 42 from the brain,” says Randall J. Bateman. “In this new study, we show that at over 80 years old, it takes more than 10 hours.”
Research has uncovered that a protein called amyloid beta 42 (a natural byproduct of neural activity), is normally removed effectively in youth but the rate of clearance was found to slow progressively with age. Accumulation of amyloid beta 42 can lead to aggregation and consequent plaque formation and a slowdown in removal was tied to symptoms of dysfunction including memory loss and personality change. The study found that the brain disposes of this protein through a number of channels, and more work could uncover ways of boosting waste mangement in ailing brains, thus avoiding this toxic accumulation.

On my tour called the “Immortality Bus,” I’m hoping to share with others that we should support a society and culture that is strongly pro-science and pro-longevity. My team and I plan to have embedded journalists aboard the bus, documenting our trip and enlivening the conversation.
Unfortunately, many people in America and around the world — especially those who believe in afterlives — are neutral or even oppose stopping biological death and aging with science. They feel it challenges what is natural in the human species. Transhumanists call these people “deathists,” those who believe and accept that death is a desirable fate.
It can be all too easy to drift through life on automatic, forever putting things off, but statistics and data can give a physicality to things we barely notice or consider most of the time. These diagrams might just give you an entirely new perspective on your life.

Peter Thiel, Larry Page, Sergey Brin, Bill Maris, Mark Zuckerberg…investment in biotech by leading figures in the world of technology is reaching new heights, with the regenerative medicine market projected to reach $20 billion by 2025 and the overall anti-aging market $345.8 billion by 2018.
These forecasts combined with a recent biotech boom mean that the economic reasons for investing are becoming clear and rising demand is virtually inevitable as the proportion of older individuals continues to grow to unparalleled levels. Bill Gates may have labelled anti-aging efforts as ‘egocentric’, but the investment doesn’t appear to be due to economic reasons alone; there is also a strong humanitarian and aspirational aspect that links some of these individuals together — the desire to utilise technology to create a better society.
‘With all being from a scientific background, Page, Brin and Maris particularly are clear in their belief that science holds the key to radically improving both the human condition and the world we live in — the pinnacle of this being radically prolonging human lifespan. In a recent Bloomberg interview Maris points out we live in an era where science can make all the tools available for any audacious vision out there…To these tech billionaires, evolution is meant to be transcended, and the resources put into organ regeneration, drugs that control ageing, or reprogramming DNA reflects their conviction that people have the right to lead better lives.’
Misfolding proteins and aggregates are a serious problem for a cell; a great range of research has been able to link poor protein ‘quality control’ with a whole range of diseases, perhaps most famously Alzheimer’s disease. Recent work also suggests that the ‘heat shock’ response, a mechanism that protects against misfolding and corrects badly made proteins, may also become impaired with aging. This gradual deterioration could turn out to be one of the most significant drivers of both aging and age-related disease.
In research that support this theory, a recent paper provides evidence that the endoplasmic reticulum (ER), a cellular compartment which is responsible for creating and correctly forming protein structures, loses its oxidative power with age. This means that it loses the ability to form a type of bond called a disulphide bridge, a strong chemical bond which normally stabilises protein structures and holds them in particular shapes. The chemical environment within the ER was shown to change with age, disrupting the delicate equilibrium in the cell and leading to increased oxidative damage in other areas. Proteins moving through the ER on a production line often require disulphide linkages to mature correctly and stabilise their structure, but without this step they’re unable to do so and remain unstable.
