00:00Just imagine, you don't have to spend money on tickets, you won't be queuing up at the airport,

00:05you don't need to fly in a plane for several hours.

00:08Imagine that a long journey from your home to some exotic country takes a couple of seconds.

00:15Yep, we're talking about teleportation.

00:18For sure, it'll be a very long time before we see a teleporter at home appliances stores

00:22next to a TV and a microwave.

00:24But we have already got potential developments that could make teleportation real in the future.

00:31Researchers in Potsdam have created an actual teleporter system

00:35that can scan an object and kind of send it to a different location.

00:39But this is not teleportation per se.

00:42This technology is based on a method of destructive scanning combined with 3D printing.

00:48So how does it work?

00:50The process begins when an object is placed in the sender unit.

00:54It's meticulously milled down layer by layer, generating detailed scans at every step.

01:01These scans are then transmitted through a secure encrypted channel to a 3D printer at the destination.

01:07The printer faithfully recreates the original item layer by layer,

01:12effectively achieving a form of teleportation.

01:15This way, scientists have a compact, self-contained device

01:18that can relocate inanimate objects over distances.

01:21You can put an item in the sender unit, enter the address, and press the button.

01:27Abracadabra.

01:28The system is called Scotty, you know, like the engineer in Star Trek.

01:32And it can be useful for companies selling products through home 3D printers.

01:38Scotty would create a sort of digital rights management for 3D printed goods,

01:42ensuring that each purchase results in a unique copy.

01:46For those hoping to teleport themselves straight to the beach,

01:50it looks like we'll have to wait at least another decade or two or way more than that.

01:55But if the teleportation of people was based on the Scotty technology,

02:00the machine would have to completely copy the human body.

02:03Not just the skeleton, muscle tissue, skin, and hair, but also the brain.

02:09Billions of neurons of the most complex computer on the planet would have to be copied exactly.

02:15The machine would split you into molecules and atoms,

02:17and then scan and copy them at another point.

02:20But if this ever happened,

02:22could you be sure that it was you who teleported and not your exact twin?

02:27Would you agree to such an experiment?

02:30Not me, baby.

02:31So, let's consider a simpler but still awesome technology.

02:36Like a technology that protects houses from earthquakes by raising them above ground.

02:42Japan is on the cutting edge of earthquake safety

02:44with a groundbreaking technology that lets homes float just above the ground,

02:50ready to ride out tremors.

02:52A house gets support from a wide airbag that holds the building steady during an earthquake.

02:57The system uses compressed air for a sleek, high-tech solution.

03:02Each home comes with a special foundation, a smart sensor, and an air compressor.

03:07The sensor is like the house's watchdog, constantly monitoring for seismic activity.

03:13When it detects shaking, it sends an alert to the air compressor outside.

03:16In seconds, the house can lift up to 1.2 inches, hovering safely above the ground while the earth rumbles beneath.

03:25Once the shaking stops, the air is released, and the home gently settles back down.

03:30It's like a dance of safety and innovation, ensuring peace of mind during even the fiercest quakes.

03:36We all know about airbags in cars, but what about a motorcycle or bicycle?

03:43Yes, people wear a helmet, and it's safe, but one Swedish company has invented a bicycle airbag.

03:49And the tests of this airbag showed better results than the tests of protective helmets.

03:55When a crash happens, the airbag pops up and immediately turns into a one-time superhero,

04:01ready to save the day but not be used again.

04:04Thanks to some fancy sensors and a snazzy algorithm, it's got your back, literally,

04:10by monitoring your moves and springing into action in just one-tenth of a second to cushion that unexpected tumble.

04:18Testing has shown that this nifty safety system scores a fantastic four-and-a-half stars for protection,

04:24outshining many other helmets that can barely manage four.

04:28Plus, it's designed to fend off those pesky side impacts and twisting forces.

04:32But here's the twist.

04:35While this tech is pretty amazing, it's still got some room for improvement.

04:39Sadly, the company behind this brilliant invention hit a bump in the road and went belly up.

04:45News says they haven't aced all of their crash tests.

04:48So while the airbag is a fantastic idea, it looks like there's still some work to be done.

04:53Now, meet a technology that will give you a reason to start making videos about birds.

05:01This gadget gives you a front-row seat to the avian action right from your phone.

05:07With its super-smart AI bird recognition tech,

05:10this feeder automatically captures stunning videos of your feathered friends.

05:14The feeder comes packed with a sharp 1080p camera, complete with night vision.

05:20So whether it's dawn or dusk, you'll never miss a beat.

05:24Or a beak.

05:25Rain or shine, this bird feeder is tough enough to handle it all.

05:29It's waterproof and dustproof.

05:31Plus, with two solar panels on the roof, it soaks up sunshine all day long.

05:36So you won't have to mess with batteries.

05:38Meanwhile, have you ever heard of Google Jaccard technology?

05:44The company has recently shut down this project, but it was still a pretty impressive innovation.

05:50Jaccard inserted touch sensors and haptic feedback right into your clothes.

05:55Yep, that meant you could rock smart jackets and backpacks

05:58that let you control your phone without even touching it.

06:02Wait, are we becoming that lazy?

06:05Well, imagine this.

06:06A quick double-tap plays or pauses your music.

06:10A gentle brush on the smart fabric changes the track.

06:14And if you cover a sensor for a second, boom!

06:17You mute those pesky notifications.

06:19How cool is that?

06:21It's like having a personal assistant right in your wardrobe.

06:24Hey, get out of my pants!

06:26Meanwhile, picture a train gliding on a cushion of air.

06:30Or a sleek capsule zipping along at 760 mph inside a vacuum tube.

06:36It's not sci-fi.

06:37It's something called hyperloop.

06:40Inside, it feels like you're in a spaceship.

06:42You can kick back in a comfy chair, strap on your seat belt, and get ready for an incredible ride.

06:48As you zoom through at almost the speed of sound, you won't even feel a thing.

06:53If you were watching from the side, this train would whiz past you faster than you can blink.

06:58It's all about that sleek design.

07:01You can think of it like air hockey, where the puck glides effortlessly over a field thanks to a thin layer of air.

07:08The puck floats above the surface, moving freely without fiction.

07:12That's how the hyperloop rolls, too.

07:15Instead of air coming from the tube, it's coming from the capsule itself, creating a tiny gap between the capsule and the tunnel.

07:22An electric motor then sends the train flying.

07:26Now, you might wonder about air resistance.

07:29At super high speeds, dense air can really slow big objects down.

07:33To avoid this, the hyperloop travels inside a tube where the air density is lower.

07:38Special pumps will suck out some of the air along the route, but it won't be a perfect vacuum.

07:43Getting that just right takes a ton of energy.

07:46And here's a neat trick.

07:48A fan on the front of the capsule will push any incoming air underneath it.

07:53It's kind of like how pneumatic mail works, where parcels zoom through pipes thanks to air pressure.

08:00Solar panels on the tube's roof will help power this whole thing.

08:04Elon Musk dreamed this up a while back, but there are some challenges to tackle.

08:09Keeping that air cushion just right over long distances is key.

08:14Any cracks, bumps, or even a little earthquake could throw a wrench in the works.

08:19The technology is not quite ready for prime time, but if engineers nail it, we could travel from Los Angeles to New York, arriving two hours faster than a commercial jet.

08:32Now, air taxis and self-driving cars are great for flying high or cruising on smooth roads.

08:38But what happens when you need to navigate through rough terrain like mountains, mud, or swamps?

08:44Enter Hyundai's incredible innovation, a futuristic car that's ready for any challenge.

08:50Instead of wheels, this amazing vehicle has legs.

08:54This walking vehicle can tackle tough landscapes with ease and comfort.

08:58Each leg is designed with joints that bend, allowing it to conquer everything from steep hills to the summit of a volcano, hopefully not when it's erupting.

09:08So, you're at a festival and it's getting really rowdy.

09:16Your friend has gone to grab some drinks, and you've lost sight of him.

09:20Suddenly, his voice sounds loud and clear in your ears, asking what drink he should get for you.

09:26Now, are we in a sci-fi movie or what?

09:29No, apparently that's what scientists can do now.

09:32They've made a sound that can travel through space and reach just your ears in the crowd.

09:37Researchers conducted a new study and found a way to make tiny pockets of sound stay in one place.

09:45These pockets don't spread around like normal sound, and it means we can now create sound exactly where we want it,

09:53like sending it only to one person in a room.

09:56This discovery might totally change the way we enjoy music, talk to people, or experience sound in games and virtual spaces.

10:03You see, sound is just vibration moving through the air in waves.

10:08When something moves back and forth, it pushes and pulls the air.

10:12That movement creates sound waves.

10:15The speed of these waves is called frequency.

10:18If this frequency is low, we hear a deep sound, like a bass drum.

10:22When the frequency is high, it produces a sharp sound, like a whistle.

10:26Now, at the same time, it's hard to control where sound goes, because of something called diffraction.

10:34This just means that sound waves like to spread out as they move.

10:38This is even worse with low-deep sounds, which have long waves and are harder to keep in one place.

10:44Some devices, like parametric speakers, can send sound in one direction, like a beam.

10:49Even then, the sound is still heard along the whole path.

10:53It doesn't stay in one spot.

10:55But now, researchers have actually figured out how to do that using something called ultrasound

11:01and a special trick called non-linear acoustics.

11:06Now, ultrasound is a sound that's too high-pitched for people to hear.

11:10Anything above 20,000 hertz or 20 kilohertz.

11:14Even though we can't hear it, it still travels through the air like a regular sound.

11:18It's used in things like medical scans, for example, ultrasound imaging, and in some industrial tools.

11:25So, in their research, scientists use ultrasound to carry normal sound.

11:30They made ultrasound waves move through the air quietly,

11:33and the actual sound only became audible right where they wanted it to.

11:38Now, usually, sound waves just add up when they meet.

11:41That's called linear behavior.

11:43Nothing special happens, the sounds just mix together.

11:46But when sound waves are strong enough, they can act differently.

11:50They combine in a non-linear way, which can create new sounds that weren't there before.

11:56Using this knowledge, the researchers took two ultrasound beams, each at a different high frequency.

12:02By themselves, these beams were totally silent.

12:05But when they met in space, they mixed in this non-linear way and created a brand-new sound wave that we could hear.

12:13And that sound only appears in the spot where the beams cross.

12:18Normally, sound travels in straight lines, unless it bounces off of something.

12:22But researchers used special materials called acoustic metasurfaces.

12:27It allowed them to bend those ultrasound beams as they moved.

12:31Kind of like how glasses bend light.

12:33By changing the timing of the waves really precisely,

12:38they can curve the sound around objects and make it reach an exact point.

12:43Like sending it around a corner and having it land right by your ear.

12:47Now, let's say they use one beam at 40 kHz and the other at 39.5 kHz.

12:53When these beams meet, they create a sound at the difference between those two.

12:580.5 kHz or 500 Hz, which is a frequency we can hear.

13:04But again, you only hear it right where those beams intersect.

13:08Everywhere else, silence.

13:10Even so, you could send sounds straight to one person without headphones and not disturb anyone around them.

13:18Imagine walking through a museum and hearing an audio guide just for you.

13:22No headphones needed.

13:24Other people nearby could be listening to totally different information without any sound overlapping.

13:29In a library, students could listen to lessons without bothering the person next to them.

13:35In a car, this tech could let passengers listen to music while the driver hears only the GPS directions.

13:42Aw, man!

13:43In offices, it could create small zones where people could have private conversations without being overheard.

13:49It could also work the other way around, by cancelling noise in a certain spot to make things quieter.

13:55This could help people concentrate better at work or even reduce noise in busy cities.

14:01Now, this isn't something you'll be able to buy just yet.

14:04There are still some challenges.

14:06For one thing, the sound quality can get a bit distorted because of how the ultrasound waves interact.

14:13Also, turning ultrasound into sound you can hear takes a lot of energy,

14:17which makes it less efficient right now.

14:20Still, the idea of creating audio bubbles is absolutely fantastic.

14:25It's not the only recent invention that explores sound.

14:29How about AI headphones that allow you to focus on just one voice?

14:34You might say that these days, we already have noise-canceling headphones that can block out sound,

14:39but you really don't get to choose what to focus on or when.

14:43But researchers from the University of Washington have come up with a smart solution.

14:49They've built a system called Target Speech Hearing that works with AI and headphones.

14:55You just look at the person you want to hear for about 3 to 5 seconds,

14:59and the headphones will lock on to their voice.

15:02After that, the headphones block out all the other sounds around you

15:06and play only that person's voice in real time.

15:09And even if you're in a loud place or you walk around and aren't facing them anymore, it still works.

15:15The headphones aren't for sale yet, but the code is out there, and others can experiment with it.

15:21Let's dive deeper into how it all works.

15:24You wear regular headphones that have built-in microphones.

15:28When you want to hear someone, you just press a button and look at them while they're speaking.

15:32The system figures out who you want to hear by measuring when their voice hits both microphones at the same time.

15:40There's a small margin of error, but it works pretty well.

15:43That sound is then sent to a small computer built into the headset.

15:47The AI software listens and learns the voice you've chosen.

15:51From that point on, the system keeps picking out that person's voice and playing it clearly to you,

15:57even if you're both moving around.

15:58The more that person talks, the better the system gets at recognizing and focusing on them.

16:05They tested this on 21 people, and on average, the sound of the selected voice

16:09was rated nearly twice as clear as the normal unfiltered sound.

16:15Now, right now, the system can only focus on one speaker at a time,

16:19and it has trouble if another loud voice is coming from the same direction.

16:23But if the sound isn't clear enough, you can just do another enrollment to help it improve.

16:29They're now working on making the text small enough to fit into earbuds and hearing aids.

16:35Scientists have also found that the human ear itself has hidden modes.

16:40Researchers at Yale University were just trying to figure out how our ears can pick up super quiet sounds.

16:45And in the process, they discovered a hidden way that the ear might handle low-frequency sounds.

16:52You know, those deep, rumbling ones?

16:54It helps us hear better without getting overwhelmed by noise.

16:58Scientists think that the cochlea, which is the spiral-shaped part of the inner ear,

17:03might be using a whole set of low-frequency mechanical modes.

17:07Basically, when sound comes into your ear, it creates tiny vibrations that travel through the cochlea.

17:13Inside, little hairs on a membrane detect those vibrations and send signals to your brain so you can hear.

17:21The problem is that these vibrations can weaken as they travel, making sounds dull or quiet.

17:27Now, we already knew that certain parts of these hair cells can boost those signals with a well-timed kick

17:33to make the sounds clearer, kind of like a built-in amplifier.

17:37But now, it looks like the ear has another trick up its sleeve.

17:41It can also tune and boost sound more broadly, especially for low-frequency sounds.

17:47And it does this without making up fake sounds or overreacting.

17:52New models show that the hair cells can work not just individually, but also in larger groups all at once.

17:58This lets the ear adapt and control how it processes vibrations.

18:03For lower-pitched sounds, even big sections of the membrane in the cochlea can work together

18:08to keep the sound clear and avoid overwhelm in the system.

18:13This discovery might explain how we're able to hear such quiet low sounds in the first place.

18:18That's it for today.
