In his fascinating new book, “21 Lessons for the 21st Century,” the historian Yuval Noah Harari creates a useful framework for confronting these fears. While his previous best sellers, “Sapiens” and “Homo Deus,” covered the past and future respectively, his new book is all about the present. The trick for putting an end to our anxieties, he suggests, is not to stop worrying. It’s to know which things to worry about, and how much to worry about them.

An interview with Methuselah Foundation’s founder David Gobel.


David Gobel is an inventor, philanthropist, futurist, and passionate rejuvenation advocate and supporter; he’s known for co-founding Methuselah Foundation with Dr. Aubrey de Grey and for proposing the intriguing concept of “longevity escape velocity”, but his achievements and successes extend far beyond that. David has kindly granted LEAF a most interesting and detailed interview.

If you’re not familiar with the Methuselah Foundation, it is possibly the oldest organization active in the field of rejuvenation advocacy and support; it also works as an incubator for startups working in rejuvenation research and has helped kickstart many of the projects we talk so much about on our website. If you like, you can find more information on Methuselah Foundation in our older article.

We hope you enjoy Dave’s replies as much as we did!

Space is all the rage, so it seems. The number of small spacecraft – including satellites – being manufactured has rocketed in recent years, and future forecasts are equally explosive. The first-ever internationally agreed requirements have just been published, enabling the industry to cruise even higher.

The small satellites industry is taking off. According to a recent report by SpaceWorks1), an aerospace company focused on delivering cutting-edge flight and space technologies, 2017 showed a 205 % increase in small satellite launches compared to 2016, with a record number still awaiting launch. What’s more, forecasts for future spacecraft production, often by new entrants to the industry, look equally celestial.

But producing these spacecraft involves some very specific requirements that newcomers to the market may not be aware of. To help harmonize the sector, ISO has just published the first-ever international technical specification for small spacecraft, which states the minimum requirements that every small spacecraft needs to comply with regardless of its mission.
