The topic of healthspan is increasingly being raised in the popular media, but what does it really mean? Simply put, healthspan means the period of your life in which you remain healthy and free from age-related diseases. The Roman poet Virgil once said “The greatest wealth is health”, so the concept of healthspan was something valued as far back in time as then.

Today, we are going to take a look at how we have been trying to increase human healthspan in the past and what science is doing now to take us to new frontiers of health through a new approach to medicine called rejuvenation biotechnology.

So, why is healthspan becoming such a popular saying, and why is it appearing frequently in articles and in other media now? Quite simply, the advances in our understanding of the aging processes and our ability to do something about them has reached the point at which taking measures to increase healthspan is now plausible.

The Canadian Space Agency (CSA) has awarded $1.85M contract to the University of Waterloo for the Quantum Encryption and Science Satellite (QEYSSat) mission.

The QEYSSat mission was one of two projects cited in the 2017 budget when it was unveiled in March of this year. In April, the government sent Innovation Science and Economic Development (ISED) Minister Navdeep Bains to the CSA’s headquarters to formally announce the funding for the QEYSSat mission along with funding for a radar instrument that will be developed for a future orbiter mission to Mars and to announce the Canadian CubeSat Project. The $80.9M of funding would be over five years.

A short history of the QEYSSat mission.

The internet may be an international system of interconnecting networks sharing a rough global consensus about the technical details of communicating through them – but each country manages its own internet environment independently. As the U.S. debate about the role of government in overseeing and regulating the internet continues, it’s worth looking at how other countries handle the issue.


As the U.S. weakens its protections for internet users, it risks falling behind the rest of the world.

Scientists have identified a mysterious genetic mutation that effectively negates the sensation of pain, enabling people with the rare anomaly to persevere effortlessly through extreme physical discomfort.

The gene variant – identified in an Italian family who feels almost no pain even when seriously injured – could help scientists find new treatments for chronic pain that mimic the family’s unusual gift.

“We have spent several years trying to identify the gene that is the cause of this,” molecular biologist James Cox from University College London told The Independent.

The flip side is there’s only a tiny storage density improvement in play here; Toshiba is using 1.56TB platters, while its competitors are back on ~1.5TB. Shoving more platters into a drive while retaining a 3.5-inch form factor is mechanically impossible after a certain point. And while hydrogen gas is only about half as dense as helium, that’s still a much smaller improvement than what helium offered compared with Earth’s atmosphere.

The MG07ACA14TE (14TB) and the MG07ACA12TE (12TB) are both 7200 RPM drives with SATA 6G support. The 14TB drive is rated for 260MB/s of sequential read performance, while the 12TB drive is rated for 250MB/s. Toshiba has talked about a 16TB drive, according to Anandtech, but that much space would require roughly 1.8TB platters, a significant jump over what the company is using today.

Seagate has pledged to bring the next leap in recording technology, Heat-Assisted Magnetic Recording (HAMR) to market, alongside helium-filled drives of at least 18TB. Those drives could be on the market as soon as 2018. Western Digital is backing a technology known as MAMR (Microwave-Assisted Magnetic Recording), in which microwave fields emitted by a spin-torque oscillator allows drives to use weaker magnetic fields when writing data. This is supposed to boost densities up to 4.5Tbits/inch over time, which would theoretically enable 40TB hard drives, eventually. MAMR may be ready by 2019, though all timelines should be taken provisionally; some of these technologies have been in the works for a decade or more.

The genetic atlas revealed new information about health risks, ancient political borders, and the influence of Vikings.

Learn how your family history is connected to the human journey with National Geographic’s Geno 2.0 DNA ancestry kit.

A new “DNA atlas” of Ireland is revealing some of the surprising ways historic kingdoms have influenced populations on the island—and it offers the first genetic evidence that Vikings intermingled with ancient Irish peoples.

Bitcoin has many characteristics of a currency. It is portable, fungible, divisible, resistant to forgery, and it clearly has value. Today, that value came close to $20,000 per coin. Whether it has ‘intrinsic value’ is somewhat of a moot question, because the US dollar hasn’t exhibited this trait since 1972. Today, economists don’t even recognize the intrinsic value of gold—beyond a robust, international, supply-demand network.

Lately, Bitcoin is failing as a viable currency, at least for everyday consumer transactions. The settlement of each transaction is bogged down with long delays and a very high cost. The situation has become critical because of squabbling between miners, users and developers over how to offer speed transactions or lower the cost of settlement. Bitcoin forks and altcoins such as Dash and Bitcoin Cash demonstrate that these technical issues have solutions. Since Bitcoin is adaptable, I believe that these issues are temporary.

But an interesting question is not whether Bitcoin will eventually become a consumer currency. it is whether Bitcoin can distinguish itself as a store of value, rather than just an instrument for payment or debt settlement. After all, a Visa credit card, a traveler’s check and an Amazon gift card can all be used in retail payments, but none of them have value unless backed by someone or something. US Dollars on the other hand are perceived as inherently valuable. They carry the clout and gravitas of institutions and populations, without users questioning from where value arises. (This is changing, but bear with me)…

What about Bitcoin? Does owning some bitcoin represent a store of value? Yes: It absolutely does!

Bitcoin is a rapidly maturing two-sided network. Despite a meteoric rise in exchange value and wild fluctuations during the ride, it is the epitome of a stored value commodity. Regardless of government regulation, adoption as a consumer payment instrument, or the cost and speed of transactions, it has demonstrated stored value since May 22 2010, when Laszlo, a Bitcoin code developer, persuaded a restaurant to accept 10,000 BTC for 2 pizzas.

The “currency” accepted by the pizza parlor wasn’t a gift card. It was not backed by a government, a prior deposit, dollars, gold, the promise of redemption, or by threat of force or blackmail. When a large community of individuals value, exchange, and can easily authenticate something that has none of those underpinnings, that thing clearly has stored value.

In this case, value arises from its scarcity and a robust supply-demand-network. Because its value is not tied to a government or to other commodities, its exchange rate with other things will be bumpy, at first. But as it is recognized, traded and adopted as a stored value token, the wild spikes will smooth out.

A tipping point will precipitate rapid adoption when…

  • when some vendors begin to quote prices in Bitcoin (rather than national currency)
  • when some of these vendors retain a fraction of their bitcoin-revenue for future purchases, payments or debt settlements—rather than converting revenue to fiat/national currency with each sale

Bitcoin is clearly a store of value, and it is beginning to displace gold and the US dollar as the recognized reserve currency (it is gradually becoming the new gold standard). But before Bitcoin can serve as a widely adopted everyday currency (i.e. as a payment instrument—with or without the stored value of a currency unto itself), it must first incorporate technical improvements that speed transactions and lower cost.

This is taking longer than many enthusiasts would have liked. But, that’s OK with anyone who keeps their eye on the big picture. Democracy is sometimes very sloppy.
