Inverse Daily: Sleeping fewer than 7 hours may be shortening your telomeres

Shorter telomeres are considered a biomarker for premature aging, suggesting a link between sleep and biological age.

As we approach the end of the decade, we crane our necks toward the 2020s. We squint at the future to see that it’s everything between good and bad. There are inane Elon Musk tweets. There are cures. There is another Star Wars movie. There are wars. Facebook still exists. There are better treatments for mental health. And that’s what you’ll get in today’s edition of Inverse Daily. We have stories about the problems and solutions with hydroelectric power, global hunger, artificial intelligence, and more.

I’m Nick Lucchesi, executive editor at Inverse. Let’s dive into what the future looks like today.

“People who are bankers are not particularly dishonest.”

— Michel Maréchal, whose 2014 study on the honesty of bankers contrasts with a new one released this week.

How do you sleep at night?

Did you know that sleeping fewer than seven hours a night — a “magic number” that’s recommended by the National Sleep Foundation — could be linked to premature aging in the body?

Research released by scientists in Singapore found that when people slept for fewer than five hours per night, there were markers of premature aging in their bodies.

Specifically, their telomeres — chains of nucleotides at the ends of chromosomes — were shorter than those seen in people who slept at least seven hours. Telomere length is a sign of biological aging; the shorter they are, the “older” the body is, no matter how many years, hours, or days you’ve been on this planet.

A neat thing about this study is that they found this pattern using FitBit wearables. Basically, the scientists were encouraged by the fact that FitBits were extremely good at tracking sleep.

He’s got the bill

While some in the Western world can stop by CVS to pick up a bottle of 90 multivitamins, getting nutrients in the developing world isn’t that easy. Micronutrient deficiency is a huge yet hidden problem, as almost a third of the global population misses out on key vitamins and minerals every day. The results come in the form of impaired growth, cognitive disorders, blindness, and even death. A new invention may have solved a key stumbling block in the effort to deliver optimal nutrition.

Scientists have created a microparticle-based shield that can keep micronutrients protected until they reach the mouths of malnourished people across the globe.

Like a bullet train, the new microparticle platform can preserve the nutritional quality of foods like fortified bread and maize on their journey.

Developing the microparticle shield was a game of trial and error, spurred by the insight, funding, and encouragement of Bill and Melinda Gates and their foundation. (Bill even tried the fortified bread and couldn’t tell the difference from regular non-fortified bread, says Ana Jaklenec, senior author of the study.)

The computer wore tennis shoes

Beyond cortical and limbic systems, Elon Musk’s Neuralink could add a third layer of digital superintelligence to humans and avoid artificial intelligence enslavement, Musk claimed Tuesday.

The brain-computer linkup firm is working to treat medical conditions using its implanted chip as early as next year, but during a podcast appearance, Musk reiterated his belief that the technology could avoid some of the worst consequences of advanced machines.

“It’s important that Neuralink solves this problem sooner rather than later, because the point at which we have digital superintelligence, that’s when we pass the singularity and things become just very uncertain,” Musk said during an interview with MIT professor Lex Fridman.

Melt with you

Vast, rapidly melting glaciers pose enormous risks to humans — the water they generate leads to sea level rise, epic flooding, and a loss of water sources.

As ice continues to disappear apace, new research suggests there may be two beneficial opportunities.

Once-frozen glacier basins could provide humans with both a huge amount of energy — in the form of hydropower — and a reservoir for storing clean water. (The counterintuitive findings were published this week in the journal Nature.)

But before you get too excited at the idea of there being a small positive among the devastating effects of climate change, a separate study suggests that hydropower — commonly considered to be as green as other renewable energy sources, like wind and solar — emits more greenhouse gases than we thought.

Programmed to … kill

If we don’t adopt legislation to stop killer robots from proliferating soon, they could become commonplace. That’s the message of a new report from the peace advocacy nonprofit PAX.

The report claims weapons manufacturers and countries are moving toward producing autonomous weapons systems. These systems, the report warns, could cascade into immoral and unethical use.

They’re coming sooner than you think →

Meanwhile …

  • Automation could kill 800 million jobs within about 15 years, according to a new study.
  • Some diehard Pokémon fans are threatening to revolt against Sword and Shield.
  • The Mandalorian trailers may have already revealed what happens in Episode 2.
