Robot Muscle, Plant Tattoos and more — Mind Blow #116


An 11,500-year old infant has been unearthed
in Alaska — and “Sunrise Girl-Child’s” DNA suggests that rather than several migratory
waves over time, all Native American ancestry traces back to one massive migration. And to breed plants that use water more efficiently,
researchers at Iowa State University are measuring exactly how long it takes for corn plants
to move water from their roots to their leaves using graphene plant tattoos. Vsauce! Kevin here. This is Mind Blow. The world’s first photovoltaic expressway
has debuted in China. Qilu Transportation Development Group has
built a 1-kilometer stretch of road that has a bottom layer of insulation, a middle layer
of solar-powered batteries, and a top layer of transparent concrete. The electricity will power highway lights,
cameras, and signs — but the developers are hoping that it will power electric cars and
melt snow in the future. But the cost is high — it’s $458 per square
meter compared to $5 for a standard asphalt road — and the 1 kilometer stretch will only
create enough electricity to power 93 homes for one year. So this has a long way to go before it becomes
like a thing. Shrimp claws took 150 million years to develop. A study of 114 species of shrimp has revealed
how they’re able to snap their claws. Researchers at the University of Alberta found
what they call ‘extreme biology’ — shrimp evolving to make use of an air vacuum that
stores and expends energy… in a snap. Shrimp use the snapping motion to communicate,
attack prey, and defend themselves. So that 150 million years was totally worth
it. And shrimp are delicious. Millions of diabetics could benefit from a
skin-like surface. Currently, diabetics have to prick their skin
to monitor blood sugar levels — not only is it painful, but it can result in infections
and other complications. But researchers at in Beijing have found that
ultra-thin, skin-like biosensors can reliably monitor glucose levels in a non-invasive way
— which means more comfort and better monitoring. 20 years ago, Apopo started training “Hero
Rats” to detect landmines and diagnose tuberculosis — and they’re getting more efficient. It takes 4 days for a lab technician to evaluate
100 samples of sputum or for a minesweeper to cover an area the size of a tennis court. A Hero Rat can do either job in just 30 minutes. Research and development includes teaching
rats to indicate the presence of mines by flipping a collar switch and identifying the
presence of new diseases. So thanks, rats. We tend to think of robots as rigid, metal
creations — for now. The Keplinger Research Group at the University
of Colorado is developing ‘soft’ robots that mirror the makeup and movements of biological
muscle tissue. Soft robotics allows machines to be as forceful
or gentle as they need to be, and researchers say the muscle-like electrical actuators that
make industrial and commercial applications possible can be produced now for about 10
cents. Humanity has milked its first platypus. The male platypus has a venomous spur on its
hind feet that it uses to compete with other males for mates, but until now, no one has
extracted the venom. Tim Faulkner of the Australian Reptile Park
successfully took a sample of venom which includes a hormone that may be useful in treating
diabetics. The world’s first DJ robot is spinning in
the Czech Republic. A club in Prague challenged robotics manufacturer
KUKA to make a robotic arm that controls the action and can respond to the crowd. And the challenge was accepted. But the robot music revolution isn’t happening
quite yet — the club is alternating between human and robot DJs every hour. Do tiny sea turtles that hatch on the beach
get tired when they don’t make it to the water quickly enough? Researchers at Florida Atlantic University
put them on a treadmill to find out. Sea turtles crawl toward the light, which
means urban glows can disorient them. FAU researchers found that the turtles crawl,
rest, and keep crawling even after hours of effort. They’re little crawling machines and as
a wise zombie child once said, “I like turtles.” At Columbia University’s Robotics and Rehabilitation
Lab, exoskeletons are helping train people to walk again…. The goal is to be able to build and design
lightweight, wearable exoskeletons. An exoskeleton that doesn’t have explicit
joints that can either assist them in their movement or train them so that they can eventually
walk without these exoskeletons. To come up with novel inventions in science
and technology, we need to develop our own toolkits and frameworks for understanding,
instead of blindly memorizing formulas. Brilliant’s interactive problems are a great
way for you to really understand math and science. They have everything from Number Theory, to
Mastering Casino Blackjack, or this one I really like that explains Solar Energy from
the ground up – we all know that solar panels absorb the Sun’s energy, but what is it that
they actually do? So click the link at the top of the description

  1. I loved the part where he stopped to explain that the electric roads have a lot of flaws and are still a very early technology. Makes the video less Top 10-y and more interesting.

  2. 0:39
    Didn't Thunderf00t make it clear that that's never going to work?
    Why put the panels on the road anyway? Why not to its side so they generate more electricity?

  3. SOLAR FRICKIN' ROADWAYS
    edit: i know this won't help, since the people behind the project prolly won't read this, but i like sharing ideas: what if they put piezo (spelled correctly?) electric crystals into the road, to get just slightly more power with every car that drives over them?

  4. Solar roadways won't ever be as costeffective as solarpanels on Roofs. Just watch EEVBlog on YouTube. There is everything explained why solar roadways aren't the future.
    EDIT: link: https://www.youtube.com/watch?v=HOZBrHqTJk4

  5. That disappointed you fell when Kevin makes a reference you like so you go to like the video but you’ve already liked it and can’t like it again.

  6. Comparing the costs of photovoltaic roads to just regular asphalt is really strange. It's not like they're trying to just make an asphalt road…. The correct comparison should be to combined costs of regular solar panels and an asphalt road. In which case the separate elements are still way cheaper. Soon, once the so called inventors have received their fat funding, someone with an actual brain will suggest to just build asphalt roads with a couple of solar plants wherever they need them, which will be a tenfold cheaper. (Which is what China has been doing for years now: Building massive solar plants, while the West sits on their ass and waits for the oil to run out before getting into action).

  7. Lots of diabetes treatment in this one. Gel packs and platypus venom. Definitely a mix of new tech and old school.

  8. Hey V Sauce!!!! Thanks so much for covering our work on soft robotics. For anyone that is interested please make sure to check out our other videos that explain how the HASEL actuators work! And feel free to drop me a line with any questions. – Tim, Keplinger Research Group

  9. The chinese solar road failed epic.It got totally smashed by traffic in just a few days.Also it has no batteries,it's just solar panels.

  10. For all the enthusiasts or anyone who cares to check it out really, I would like to introduce you to what I believe to be the most ambitious project of all time.

    Please leave a like so vsauce can see it if you would like him to make a video about it.

  11. 1:15 wait what? How is "one year" a thing there? Do you mean in the complete lifespan of the roadway? Or what timeperiod?

  12. Ouch! $345 in 1971 what a lot of money. The minimum wage was $1.60. My parents paid $75 for the rent on a 2 bedroom apartment in NYC. in 1971. But then Nixon took America off the gold standard and inflation ran like a cat on fire. $16.37 in 1970 = $100 today 2018 Thanks, Nixon I have a dollar that is worth 8 cents.

  13. Pleas tell me I wasn't the only person reminded of the Animals Clearing Mine Fields in Africa video from years ago: https://www.youtube.com/watch?v=CiTO81XF15c – Yes I know it was fake, but it's still hilarious.

  14. Photovoltaic roads are not useful, sense trucks very heavy and roads break very fast.
    Diabetes doesn't exist in nature
    A delusion made in the minds of the humans created by the devil intended to be used against man kind as usual more lies from Bios

  15. You do realize like 90% of so called "companies" are owed by the CCP right? So then the information they give out is incredibly distorted? You DO know this right?
    STOP COVERING BS CHINA DOES; ITS JUST THAT. BULL SHEIT.

  16. I LOVE the old tech videos at the end. It's mind boggling how much we advanced and changed even within one life time.

  17. How can that calculator be $345 when a ti84 nowadays costs only around $200? I guess with further development of technology, it can become much more affordable, so it's not unlikely these awesome innovations will be put into the hands of consumers sometime in the future.

  18. damn…great find…new here…one of the best channels ive found so far on youtube…cracking stuff fellow!…(only been watching youtube 2 years what do you want?) hahhahaha #WorldsFinest #nkyc33

  19. Hi Science Community!!! CHECK OUT my science competition video https://www.youtube.com/watch?v=yT44MfGOaf4 I'm a Canadian doing really cool cutting-edge research, any support would be really appreciated, I'm trying to find science lovers out there 🙂

  20. 0:47 yes. putting solar panels on roads is tottaly a good idea.
    not like cars will drive over them with gravel and other material.
    damaging the panels. not like poeple will steal them.
    not like them being faced flat instead of being angled will produce little to no power.

    do some research before talking about things. just because some millionar said "im going to do (blank)" does not mean its a good idea.

    and guess what! you can just place those solar panels, on the roofs of houses. and angle them towards the suns arc in the sky. and generate alot more power.
    and you dont need to repair them, because cars arent running over them 24/7.
