Scientists at Albert Einstein College of Medicine have found that stem cells in the brain’s hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan. The paper was published online today in Nature.

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult neural stem cells, which were known to be responsible for forming new brain neurons.

“Our research shows that the number of hypothalamic neural stem cells naturally declines over the life of the animal, and this decline accelerates aging,” says senior author Dongsheng Cai, M.D., Ph.D., (professor of molecular pharmacology at Einstein. “But we also found that the effects of this loss are not irreversible. By replenishing these stem cells or the molecules they produce, it’s possible to slow and even reverse various aspects of aging throughout the body.”

What if there was one thing that you could do today to delay or improve the natural aging process in your body and mind?

At Emerge we are constantly seeking collaboration with the best minds in the world for helpful and practical advice on how to stay physically, mentally and financially healthy. Today we explore the concept of what it would be like to totally reimagine aging.

We’ve spent weeks rounding-up the top experts from around the world in various aging (also referred to as senescence) fields and asked them one question for our highly health conscious audience:

Gene editing aims to make precise changes to the target DNA whilst avoiding altering other parts of the DNA. The objective of this is to remove undesirable genetic traits and introduce desirable changes in both plants and animals. For example, it could be used to make crops more drought resistant, prevent or cure inherited genetic disorders or even treat age-related diseases.

As some of you may recall, back in May a study was published which claimed that the groundbreaking gene editing technique CRISPR caused thousands of off target and potentially dangerous mutations[1]. The authors of the paper called for regulators to investigate the safety of the technique, a move that could potentially set back research years if not decades.

This publication has been widely blasted by the research community due to serious questions about the study design being raised. One of the problems with this original paper was that it involved only three mice, this is an extremely poor number to make the kind of conclusions the paper did. There have been calls for the paper to be withdrawn and critical responses to the study.

When British billionaire Jim Mellon wants to map out an investment strategy, he likes to write a book first. Out of that process came his most recent work — Juvenescence: Investing in the Age of Longevity. Now he and some close associates with some of the best connections in biotech are using the book as inspiration to launch a new company — also named Juvenescence — with plans to make a big splash in anti-aging research.

There is a persistent view that life extension advocacy is something that does not require any investments and can be done in your spare time. Fundraising for overheads is like an elephant in the room: it is hard not to notice it is there, but people try to avoid talking about it.

The truth is, it all depends on how ambitious the goal of that advocacy is. Without a doubt, talking to friends about the promise of rejuvenation technologies or reposting research news on your Facebook feed is useful and it can be done for free.

But what if the goal is more ambitious – to change local legislation to make it more longevity-friendly, to convert decisionmakers of the state grant system to allocate more money to rejuvenation research, or to reach out to wealthy individuals able to fund more studies? These activities require money. In this article we will help you become more familiar with the notion of advocacy and the expenditures behind it.

The immune system plays a key role in tissue regeneration and the various types of immune cells such as macrophages, can help or hinder that repair process.

Inflammation is part of the immune response but with aging that immune response becomes deregulated and the inflammation becomes excessive. Excessive levels of inflammation generally speaking inhibit tissue regeneration and when that inflammation is continual, as it often is in aging, this leads to a breakdown in the ability to heal injuries.

As well as a deregulated and dysfunctional immune system aging also sees rising numbers of senescent cells accumulate which also cause inflammation. The immune system fails as we age and stops clearing away these cells leading to a downward spiral of inflammation and increasingly poor tissue repair.

Cory Doctorow has made several careers out of thinking about the future, as a journalist and co-editor of Boing Boing, an activist with strong ties to the Creative Commons movement and the right-to-privacy movement, and an author of novels that largely revolve around the ways changing technology changes society. From his debut novel, Down And Out In The Magic Kingdom (about rival groups of Walt Disney World designers in a post-scarcity society where social currency determines personal value), to his most acclaimed, Little Brother (about a teenage gamer fighting the Department of Homeland Security), his books tend to be high-tech and high-concept, but more about how people interface with technologies that feel just a few years into the future.

But they also tend to address current social issues head-on. Doctorow’s latest novel, Walkaway, is largely about people who respond to the financial disparity between the ultra-rich and the 99 percent by walking away and building their own networked micro-societies in abandoned areas. Frightened of losing control over society, the 1 percent wages full-on war against the “walkaways,” especially after they develop a process that can digitize individual human brains, essentially uploading them to machines and making them immortal. When I talked to Doctorow about the book and the technology behind it, we started with how feasible any of this might be someday, but wound up getting deep into the questions of how to change society, whether people are fundamentally good, and the balance between fighting a surveillance state and streaming everything to protect ourselves from government overreach.
