6 Ways NASA Technology Makes You Healthier

An important part of our mission is keeping astronauts strong and healthy during stays in space, but did you know that our technology also helps keep you healthy? And the origins of these space innovations aren’t always what you’d expect.

As we release the latest edition of NASA Spinoff, our yearly publication that celebrates all the ways NASA technology benefits us here on Earth, let’s look at some ways NASA is improving wellness for astronauts—and everyone else.

1.      Weightless weight-lifting

Without gravity to work against, astronauts lose bone and muscle mass in space. To fight it, they work out regularly. But to get them a good burn, we had to get creative. After all, pumping iron doesn’t do much good when the weights float.

The solution? Elastic resistance. Inventor Paul Francis was already working on a portable home gym that relied on spiral-shaped springs made of an elastic material. He thought the same idea would work on the space station and after additional development and extensive testing, we agreed.

Our Interim Resistive Exercise Device launched in 2000 to help keep astronauts fit. And Francis’ original plan took off too. The technology perfected for NASA is at the heart of the Bowflex Revolution as well as a new line of handheld devices called OYO DoubleFlex, both of which enable an intensive—and extensive—workout, right at home.

2.      Polymer coating keeps hearts beating

A key ingredient in a lifesaving treatment for many patients with congestive heart failure is made from a material a NASA researcher stumbled upon while working on a supersonic jet in the 1990s.

Today, a special kind of pacemaker that helps synchronize the left and right sides of the heart utilizes the unique substance known as LaRC-SI. The strong material can be cast extremely thin, which makes it easier to insert in the tightly twisted veins of the heart, and because it insulates so well, the pacemaker’s electric pulses go exactly where they should.

Since it was approved by the FDA in 2009, the device has been implanted hundreds of thousands of times.

 3.  Sutures strong enough for interplanetary transport

Many people mistakenly think we created Teflon. Not true: DuPont invented the unique polymer in 1938. But an innovative new way to use the material was developed to help us transport samples back from Mars and now aids in stitching up surgery patients.

Our scientists would love to get pristine Martian samples into our labs for more advanced testing. One complicating factor? The red dust makes it hard to get a clean seal on the sample container. That means the sample could get contaminated on its way back to Earth.

The team building the cannister had an idea, but they needed a material with very specific properties to make it work. They decided to use Polytetrafluoroethylene (that’s the scientific name for Teflon), which works really well in space.

The material we commonly recognize as Teflon starts as a powder, and to transform it into a nonstick coating, the powder gets processed a certain way. But process it differently, and you can get all kinds of different results.

For our Mars sample return cannister prototype, the powder was compressed at high pressures into a block, which was then forced through an extruder. (Imagine pressing playdough through a mold). It had never been done before, but the end result was durable, flexible and extremely thin: exactly what we needed.

And since the material can be implanted safely in the human body—it was also perfect as super strong sutures for after surgery.

4.      Plant pots that clean the air

It may surprise you, but the most polluted air you breathe is likely the air inside your home and office. That’s especially true these days with energy-efficient insulation: the hot air gets sealed in, but so do any toxins coming off the paint, furniture, cooking gas, etc.

This was a problem NASA began worrying about decades ago, when we started planning for long duration space missions. After all, there’s no environment more insulated than a spaceship flying through the vacuum of space.

On Earth, plants are a big part of the “life support” system cleaning our air, so we wondered if they could do the same indoors or in space.

The results from extensive research surprised us: we learned the most important air scrubbing happens not through a plant’s leaves, but around its roots. And now you can get the cleanest air out of your houseplants by using a special plant pot, available online, developed with that finding in mind: it maximizes air flow through the soil, multiplying the plant’s ability to clean your air.

5.      Gas sensor detects pollution from overhead

Although this next innovation wasn’t created with pollution in mind, it’s now helping keep an eye on one of the biggest greenhouse gasses: methane.

We created this tiny methane “sniffer” to help us look for signs of life on Mars. On Earth, the biggest source of methane is actually bacteria, so when one of our telescopes on the ground caught a glimpse of the gas on Mars, we knew we needed to take a closer look.

We sent this new, extremely sensitive sensor on the Curiosity Rover, but we knew it could also be put to good use here on our home planet.  We adapted it, and today it gets mounted on drones and cars to quickly and accurately detect gas leaks and methane emissions from pipelines, oil wells and more.

The sensor can also be used to better study emissions from swamps and other natural sources, to better understand and perhaps mitigate their effects on climate change.

6.      DNA “paint” highlights cellular damage

There’s been a lot of news lately about DNA editing: can genes be changed safely to make people healthier? Should they be?

As scientists and ethicists tackle these big questions, they need to be sure they know exactly what’s changing in the genome when they use the editing tools that already exist.

Well, thanks to a tool NASA helped create, we can actually highlight any abnormalities in the genetic code with special fluorescent “paint.”

But that’s not all the “paint” can do. We actually created it to better understand any genetic damage our astronauts incurred during their time in space, where radiation levels are far higher than on Earth. Down here, it could help do the same. For example, it can help doctors select the right cancer treatment by identifying the exact mutation in cancer cells.

You can learn more about all these innovations, and dozens more, in the 2019 edition of NASA Spinoff. Read it online or request a limited quantity print copy and we’ll mail it to you!

so on the subject of stolen property, i’ve seen various arguments on this point but it is in fact true that inheriting something from a relative, when you know full well that it was stolen, does not make it yours.

this clearly goes doubly so for powerful magical artifacts, and especially for artifacts which are strongly implied to contain part of their creator’s soul!

you can talk about consequences - maybe the artifact in question has benefits for you, maybe you’re not convinced its rightful owners would use it responsibly - but talking about the consequences doesn’t erase the fact that whatever benefits you think you’re getting are achieved through wrongful means.

which is why i, too, think Frodo should have given the One Ring back to Sauron. thief.

Okay I’m currently furious that migraines are often so blindly easy to treat and I had to find this out myself at the age of 26 when I’ve been to a neurologist since I was 11 lol so I’m about to teach you two neat and fast little tricks to deal with pain!

The first is the sternocleidomastoid muscle, or the SCM muscle.

This big red section is responsible for pain around the eye, cheekbone, and jaw, as well as some temple pain. Literally all you have to do is angle your head down a little, angle it away from the side that hurts, and then you can gently pinch and rub that muscle. I find it best to start at the bottom and travel upwards. The relief is so immediate! You can increase pressure as you feel comfortable doing so.

Here is a short and easy video showing this in action

The second is a fast and easy stretch that soothes your vagus nerve, which is the nerve responsible for calming you down. The vagus nerve, for those unfamiliar, is stimulated by deep breathing such as yawning, sighing, singing, or taking a deep breath to calm your anger in a tense situation.

You can stretch this out by sitting up as straight as possible (this does not have to be perfect to work) and interlacing your fingers. Put your hands on the back of your head with your thumbs going down the sides of your neck and, while keeping your face forward, look all the way to one side with just your eyes. Hold that until you feel the urge to breathe deeply or yawn, or until you can tell there’s a change. Then do the same thing on the other side. When you put your arms down, you should clearly be able to turn your head farther in both directions. If the first session doesn’t get rid of your migraine, rest and repeat as many times as necessary. I even get a little fancy with it and roll my eyes up and down along the outer edge sometimes to stretch as much as I can.

If you need a visual here’s a good video on it. I know some of the language they use seems questionable but this is real and simple science and should not be discarded because it’s been adopted by the trendy wellness crowd!

I seriously cannot believe I didn’t hear a word of this from any doctor in my life. Additionally, if you get frequent recurring migraines, you may want to see a dietician. Migraines can be caused by foods containing histamines, lectin, etc. and can also be caused by high blood pressure in specific situations such as exercise, stress, and even sex.

If any of this information helps you I’d love to hear it btw! It’s so so fast and easy to do. Good luck!

Wtf!!!!!!!

Faking a major event would require thousands of people. Try managing a project. getting twelve people to do what they are supposed to, on time, without blabbing early, is nearly impossible.

So as a continuation of this post I made in frustration about how anglo-centric most “must-read” book lists are, I went and found a few lists with a focus on non-English speaking authors (sorted by number of books listed):

8 Must-Read Foreign Books Translated Into English (Babbel)

The non-western books that every student should read (The Guardian)

10 best translated fiction (Independent - has suggestions regarding editions + prices)

49 Incredible Books From 49 Different Countries (Huffpost - has amazon links to all the books, which is great to find the editions but please please please support your local bookstores!!!!)

100 Must-Read Classics in Translation (BookRead - Amazon links again. Most bookstores will offer to order books for you if they don’t have them, please utilise their services and support local shops whenever possible!)

All these lists have reviews and feature books from a wide range of countries. I haven’t read every single review but I browsed the lists to make sure they wouldn’t all just name the same books and they don’t!!

I hope you’ll find inspiring new reads on those lists! :)
