[00:00:26] run on campus, it drives in
[00:00:35] no endless scrolling, no mindless violence,
[00:00:39] no porn. In late 2025, Australia
[00:00:42] introduced the world's first age limit for social media. If you're
[00:00:46] under 16, the likes of Instagram, YouTube and TikTok
[00:00:50] are off limits, but more than 80% of teenagers still
[00:00:54] industry, but as more of use them, thanks also to the platforms making it child's play to circumvent the
[00:00:58] ban.
[00:01:01] It's hardly difficult when the age check is just one question: are you
[00:01:05] over 16? yes or
[00:01:07] no.
[00:01:10] However old you are, welcome to DW Science Show.
[00:01:14] Tomorrow's a
[00:01:14] day.
[00:01:20] A few hand gestures and
[00:01:23] analyzes the data for every lap of moments later you know whether someone is over or under 18.
[00:01:27] The French startup needmand launched the border. service in December
[00:01:31] 2025,
[00:01:35] it sounds a little crazy, how does it work? it might sound
[00:01:39] hard to believe, but it's science, not
[00:01:41] magic. to take the test, users need a
[00:01:45] camera and must copy several hand movements, an AI
[00:01:50] Fungi. They come in system then analyzes them. the company says the technology is based on medical
[00:01:54] research.
[00:02:00] changes almost daily because it
[00:02:02] controls our movements, medicine has found a very precise
[00:02:05] link between a person's age and certain features of their hand
[00:02:09] movements.
[00:02:15] Drispan and his team began researching this age
[00:02:18] estimation method nine years ago. The product was
[00:02:22] commercialized only
[00:02:23] recently.
[00:02:31] It's the most important test of in three sectors, social media, adult websites and dating platforms
[00:02:34] Automobilion on Fridays on and we're in contact with Google, TikTok and
[00:02:36] Meta.
[00:02:39] Needman system is currently calibrated for age
[00:02:42] 18, the startup also plans to adapt the product to the
[00:02:46] thresholds of 15 and
[00:02:47] 16.
[00:02:50] What makes the method appealing is that users do not have to disclose
[00:02:54] personal
[00:02:54] data.
[00:02:58] The idea is fundamentally interesting. the idea is interesting because other age
[00:03:02] checks require you to show your face to camera, that
[00:03:05] also means your face is stored somewhere, raising privacy
[00:03:09] concerns, a hand is less revealing, so
[00:03:13] using this biometric feature instead of the face is an interesting
[00:03:16] idea, try biometrical features instead of the
[00:03:19] face, however a system like this cannot
[00:03:23] provide complete
[00:03:24] certainty,
[00:03:27] especially when it comes to social media. That's exactly
[00:03:31] what it would have to do, be precise.
[00:03:34] It's difficult to judge from outside.
[00:03:55] 100% certainty in borderline
[00:03:57] cases.
[00:04:07] We want to prove to the world that solutions exist for completely
[00:04:10] anonymous age verification
[00:04:14] and I deliberately say solutions in the
[00:04:17] The prototype generates only a plural.
[00:04:20] Whether border age will succeed remains to be seen, but it speaks to a
[00:04:23] growing demand for both privacy and child
[00:04:26] protection.
[00:04:30] What are Germany's inventors typically working on these
[00:04:33] days? Transport and engineering are strong,
[00:04:37] but it's the auto industry that, according to the German patent office is the
[00:04:41] top driver of
[00:04:42] innovation.
[00:04:45] Potholes after winter, they're everywhere. That means more
[00:04:49] road works and more traffic jams. Overweight
[00:04:52] trucks are particularly hard on
[00:04:54] roads.
[00:04:57] That's why the police carry out spot checks. Often they
[00:05:01] find that overloaded trucks also have brake defects,
[00:05:05] but this truck can inspect itself in real-time. Mechanical
[00:05:09] engineers at Dortmund University of Applied Sciences and their...
[00:06:12] water jets: the truck's performance is tested again and
[00:06:16] again.
[00:06:21] the sensors I showed you earlier record the secondary effects on the
[00:06:24] suspension. we can then analyze those effects using
[00:06:28] various modeling methods.
[00:06:31] the sensors beneath the trailer record everything and the software
[00:06:36] the test track. and for them it's more than just a
[00:06:39] job.
[00:07:14] everything remains in the safe
[00:07:16] range,
[00:07:18] previously he had to weigh his truck before and after
[00:07:21] loading,
[00:07:26] we no longer have to weigh the truck before and after because the system displays the
[00:07:30] weight, that saves us 10 to 20 minutes each time, by
[00:07:34] the end of the day that means at least one extra trip so I can transport another full
[00:07:38] load
[00:07:39] person
[00:07:42] also help truck drivers avoid fines for overweight
[00:07:45] loads. the system should soon be available to interested
[00:07:49] buyers.
[00:07:51] The goal is definitely to put it into practical use and get it
[00:07:55] onto the road, instead of letting the research disappear into a
[00:07:58] drawer. We're currently working with partners to industrialize
[00:08:02] the system by the end of
[00:08:03] 2026.
[00:08:07] The researchers estimate that the system will cost a few hundred
[00:08:10] euros.
[00:08:12] At any time, truck drivers could use a phone to view load
[00:08:15] distribution, tire wear and brake
[00:08:18] defects. Sensors beneath the trailer would
[00:08:22] also gather data on road
[00:08:23] conditions.
[00:08:28] As we drive along the road, an oscillating movement develops
[00:08:32] here, that allows us to assess the condition of the road
[00:08:35] surface.
[00:08:38] AI would continuously analyze the road condition
[00:08:41] data. As more trucks adopt the system, road
[00:08:45] crews would know far more precisely which routes need to be repaired
[00:08:49] first.
[00:08:53] Leaving the road for the field, we keep rolling with an
[00:08:57] AI powered tractor that operates completely on its own without a
[00:09:00] driver.
[00:09:04] Here it is, robot tractor programmed to
[00:09:07] detect and avoid any obstacle all on its own,
[00:09:11] but will it work?
[00:09:13] At the Technical University of Kaiserslautern-Landau, the
[00:09:17] robot tractor is already driving safely from the barn to
[00:09:21] the field, at least in a computer simulation.
[00:09:24] Mechanical engineer Ika Gasson helped develop it,
[00:09:27] now he and his colleagues are ready to test it outdoors.
[00:09:31] Over the past few months, Costton Banns and his team have
[00:09:35] packed the machine with AI systems. The goal is to build
[00:09:39] a tractor robot that can independently monitor, so...
[00:10:25] That's why we've installed all these red emergency buttons. When I
[00:10:28] press it, everything shuts down, the emergency
[00:10:32] brake kicks in and the vehicle stops immediately.
[00:10:35] The safety system around the vehicle can also be activated
[00:10:39] via radio and laser
[00:10:41] scanner.
[00:10:43] The robot tractor can even decide on its own to hit the emergency
[00:10:47] brake. During this test
[00:10:51] a loop, spotting obstacles like trees, lamps.
[00:11:25] we can see a silver and black sensor, that's another point
[00:11:28] cloud sensor that provides a full 360 degree view
[00:11:32] around the tractor of the tractor.
[00:11:34] To operate without help, the robot
[00:11:38] tractor has to process several gigabytes of data every
[00:11:42] second. the team has developed programs to make that
[00:11:45] possible. the data volume is
[00:11:49] overwhelming. there's all the point cloud data, the stereo camera
[00:11:53] data, the GPS data, too much for the robot to handle
[00:11:56] directly, so we have to extract the essential
[00:12:00] parts, which is what the tractor uses to drive, in simple terms,
[00:12:04] it's what it sees and what it thinks is
[00:12:06] there.
[00:12:09] initial test run showed the robot tractor is able to
[00:12:12] steer around obstacles like trees and lamp
[00:12:15] posts all on its own, until
[00:12:18] suddenly it isn't, and the team has to slam on the
[00:12:22] brakes, a pretty close call.
[00:12:29] The test will be carefully reviewed later to help the
[00:12:32] tractor become more autonomous. It's a
[00:12:35] step-by-step process of trial and
[00:12:38] error.
[00:12:41] For the next test, computer scientist Jacob will
[00:12:45] stand directly in the tractor's
[00:12:46] path.
[00:12:49] I programmed it, so if anyone has to suffer, it should be
[00:12:52] me.
[00:12:56] the day, this time the robot tractor
[00:12:59] recognizes its programmer and avoids
[00:13:02] him. for the team, the initial
[00:13:05] results are good
[00:13:06] news.
[00:13:11] as we saw, what works well is that it avoids people,
[00:13:14] it recognizes important obstacles and buildings, and that's absolutely
[00:13:18] essential, and so is the emergency stop system,
[00:13:22] which also has to work, without that, you can't use it at
[00:13:26] all. real world experiences feed
[00:13:30] back into simulations, making the tractor more
[00:13:32] independent. in just a few years, it could be
[00:13:36] working the fields all on its
[00:13:38] own.
[00:13:42] What does it take to become an inventor? First,
[00:13:44] learning to live with failure. Inventors like Thomas Edison needed
[00:13:48] incredible patience and persistence, the American
[00:13:51] declaring that genius is 1% inspiration and 99%
[00:13:55] perspiration. You also need to question existing
[00:13:59] conventions.
[00:14:04] That's what Ignat Zemorvice did when he introduced hand disinfection
[00:14:07] before and after medical examinations.
[00:14:11] In 19th century Europe, the many women dying from infections after
[00:14:14] childbirth had previously been seen as an unavoidable
[00:14:17] tragedy.
[00:14:20] But here's something inventors don't necessarily need: above average
[00:14:23] intelligence. And what does that even mean? Our viewer of
[00:14:27] Ormina from Peru had a question about
[00:14:29] that. How is IQ
[00:14:33] measured? IQ stands for intelligence
[00:14:37] quotient, but an IQ test doesn't actually measure how smart
[00:14:41] or educated someone is. The first IQ
[00:14:44] test was developed in the early 20th century by psychologist Alfred
[00:14:48] Binne. His goal was simple: he wanted to identify
[00:14:51] children who might need extra support in school. Today,
[00:14:55] IQ score mainly reflects how well someone can solve complex
[00:14:59] problems, recognize patterns and process information
[00:15:02] quickly.
[00:15:04] There are many different kinds of IQ tests. A common
[00:15:08] task involves completing a sequence of words or
[00:15:11] numbers. Here, the goal is to spot the
[00:15:15] pattern and think analytically.
[00:15:18] Another task uses geometric shapes that must be arranged or
[00:15:22] completed. These tasks measure abstract
[00:15:25] thinking, the faster and more accurately someone solves them,
[00:15:29] the more points they earn. The final number at the end is their
[00:15:33] IQ score.
[00:15:36] Most people score somewhere around 100, but a score
[00:15:40] of 130 doesn't automatically make someone a genius and
[00:15:43] 70 doesn't mean someone's unintelligent.
[00:15:47] the result may point to learning difficulties or simply show
[00:15:50] that a person is especially strong at solving logic
[00:15:53] problems. today, IQ tests are used in
[00:15:57] job applications and in scientific research. they can show how
[00:16:01] well someone recognizes patterns, navigates
[00:16:04] spatial problems, or works with logic.
[00:16:10] but there's a lot they don't measure:
[00:16:13] creativity, social and emotional
[00:16:17] intelligence, or hands-on practical
[00:16:20] skills.
[00:16:23] That's why IQ tests face ongoing criticism,
[00:16:27] especially since many of them are based on Western academic
[00:16:30] norms. And a single number can never
[00:16:34] capture who a person truly is.
[00:16:39] What are stars made of? How many
[00:16:42] colors can butterflies see? Could
[00:16:45] robots have babies one day? Do you
[00:16:48] have a science question? Then send it to us as a video, text or voice
[00:16:52] message. If we answer it in the show, then we'll send you a little
[00:16:56] gift as a thank you. So, just
[00:16:58] ask.
[00:17:03] Scientists sometimes borrow clever ideas from plants
[00:17:07] and animals and turn them into new inventions. That's exactly what researchers in
[00:17:11] Switzerland did. The result is a battery made from fungi that
[00:17:14] produces electricity. And once its job is done,
[00:17:18] biodegrades almost completely. Mushrooms and
[00:17:21] electricity. How does that
[00:17:23] work?
[00:17:27] a huge variety of species. In
[00:17:31] almost every shape and color
[00:17:34] and flourish in some very unlikely places.
[00:17:38] Some can even generate electricity.
[00:17:41] Working with researchers at Empa, Switzerland's Material Science
[00:17:45] Institute, Carolina Rayas developed a fungal fuel
[00:17:48] cell or fungal battery. Getting two different fungi to work
[00:17:52] together took years of experimentation.
[00:17:55] This is breaking down nutrients that we give it on
[00:17:58] one side, and it generates uh charged
[00:18:02] particles called electrons, and this
[00:18:05] is what goes from one side called the anode to the
[00:18:08] other side uh called the cathode and on the other side we have
[00:18:12] this different kind of fungus called white
[00:18:14] rot. the team spent three years developing the
[00:18:18] fungal fuel cell. it was a delicate balancing
[00:18:21] act. Fungi are living organisms
[00:18:25] and need exactly the right conditions: not too
[00:18:28] warm, not too cold, not too
[00:18:31] moist and not too dry.
[00:18:35] One of the biggest challenges was
[00:18:37] to try and make the electrode material and
[00:18:41] not kill the fungus in the mechanical process of
[00:18:45] mixing. The fungal cells are mixed into
[00:18:48] cellulose-based inks made conductive by carbon
[00:18:51] particles. A 3D printer then forms the two
[00:18:54] living electrodes at the heart of the fuel
[00:18:56] cell.
[00:19:00] A beeswax casing holds the cell
[00:19:02] together, add water and nutrients and the
[00:19:06] dormant fungi spring into action, the
[00:19:09] cell now begins producing electricity, apart from
[00:19:12] its removable copper contacts, it's made from biodegradable
[00:19:16] materials, conventional batteries by
[00:19:19] contrast need special collection and
[00:19:21] recycling, but many still end up in household
[00:19:24] waste,
[00:19:28] they end up in the trash, contributing to the growing problem of electronic
[00:19:32] waste, this is where batteries like ours could perhaps play
[00:19:36] a part,
[00:19:40] One possible application is environmental
[00:19:42] monitoring, powering sensors that track
[00:19:46] temperature, soil moisture or water
[00:19:49] quality.
[00:19:54] tiny current, making it suitable only for very low energy
[00:19:58] sensors.
[00:20:05] University of applied sciences, also studies
[00:20:07] materials he says that for now fungal fuel
[00:20:11] cells can't compete with conventional batteries or rechargeable
[00:20:15] cells.
[00:20:17] Fungal batteries are still at the basic research stage, it will take years
[00:20:21] before they become commercially available. but they could
[00:20:24] eventually be useful for environmental sensors in places where recovering the
[00:20:28] devices is difficult, especially if the power source can biodegrade
[00:20:31] after use, that would be a major market. and it can certainly be served in
[00:20:35] the future. The
[00:20:37] idea may hold promise for the future,
[00:20:41] but for this particular cell, the end has already
[00:20:44] begun.
[00:20:46] And as you can see, this one has already...
[00:20:50] yeah, started to fall
[00:20:52] apart.
[00:20:57] the fungal battery gradually biodegrades, leaving behind
[00:21:00] little more than a tiny lump of
[00:21:02] compost.
[00:21:08] Where can new discovery lead? often, even the
[00:21:11] scientists behind it don't know where the journey will take
[00:21:14] them. open, independent research with
[00:21:17] no fixed outcome in mind has sparked
[00:21:20] innovations,
[00:21:23] but what happens when a breakthrough isn't just useful in civilian
[00:21:26] life, but could also be used by the
[00:21:28] military.
[00:21:33] a wind tunnel in central Germany. researchers
[00:21:37] here are putting drones to the test. drones are
[00:21:40] widely used in farming, conservation and
[00:21:44] them take to the skies, there's a growing
[00:21:46] problem.
[00:21:49] The drone doesn't just fly, it also produces
[00:21:52] electromagnetic interference, that can
[00:21:55] affect mobile networks, radio communications and airports and
[00:21:59] aircraft navigation systems, and of
[00:22:02] course drones can interfere with each other too,
[00:22:06] but other drones are not the only factor, wind and movement
[00:22:10] also change signal patterns. in this wind
[00:22:12] tunnel, researchers work under controlled conditions. the goal
[00:22:16] is to make drones safer, but the research could also back fire.
[00:23:20] under attack from within our own societies and
[00:23:22] abroad, enemies of our free democratic order are
[00:23:26] challenging the freedom and independence of science. At home, the
[00:23:30] threat comes from political extremists. Abroad, we
[00:23:33] see risks from Russia, China and Iran. Even in the United
[00:23:37] States, academic freedom is under pressure. The
[00:23:40] security debate is also reshaping medical research. At Hanover
[00:23:44] Medical School, doctors use portable profusion systems to transport
[00:23:48] donor organs.
[00:24:06] can preserve organs for longer and buy us more time, that's especially important in heart
[00:24:10] transplantation,
[00:24:12] emergency almost begins to look like a planned operation,
[00:24:16] there's less pressure on surgical teams, we're no longer racing.
[00:25:50] The research itself can make you a target for people seeking knowledge you
[00:25:53] don't want to share.
[00:25:57] Research is seeking a new balance between innovation, openness and
[00:26:00] responsibility. Cooperation must continue in a
[00:26:04] world that's become much harder to
[00:26:06] navigate.
[00:26:10] Now it's your turn to get inventive. Who knows what
[00:26:13] you'll come up with. We might just make our next story about

[00:27:24] algorithms to technologies that are shaping our
[00:27:28] future today. Who leads the race, who lags behind, and
