00:00:00team was on sight, but no need, the operation went without a
00:00:03hitch. the patient diagnosed with early
00:00:07stage prostate cancer is something of a trail
00:00:10blazer.
00:00:16it's a real honor for me to
00:00:19be the first Angolan operated on via remote
00:00:23surgery. for the pool
00:00:27patel, the possibilities are immense. as long as the hospital
00:00:31can afford the equipment, procedures could even be performed without
00:00:34on-side personnel. now you can help people all over the
00:00:38world at the click of a button. right now this robot is connected to Sao
00:00:42Paulo, Brazil, it's connected to Kuwait,
00:00:45Morocco,
00:00:47of Shanghai, of Angola, and it's about to be connected to multiple
00:00:51other cities, so imagine from one place, now
00:00:55you can help people around the globe, doctor operating
00:00:58across continents. is incredible, digital healthcare can save
00:01:02lives all around the world, but technology alone can't solve
00:01:06everything, navigating issues like trust, cultural differences
00:01:10and access is the
00:01:35of Did I do the right
00:01:38thing? Should
00:01:40in I go see doctor? What should I cook for
00:01:43dinner? People are turning to artificial intelligence as a
00:01:47constant companion, chatting with it almost like it's
00:01:52a a close friend. But what is AI actually good
00:01:55at? When should we trust it, and when should we be more
00:01:59skeptic?
00:02:13decisions, replacing psychotherapist, or even a
00:02:16in friend, whatever the problem, artificial intelligence always seems to have the
00:02:20right answer, but hamburg-based AI researcher
00:02:23Maximilion Keena encourages his students to think critically about
00:02:27AI responses.
00:02:33in handle
00:02:36your
00:02:48of i could emails, your reports, even this interview, and honestly do a pretty good
00:02:51job, yeah, maybe emails, that's just
00:02:54optimization, but talking to students, interacting, showing
00:02:58empathy, taking
00:02:59of responsibility,
00:03:01of
00:03:24of
00:03:56Which of career path should I choose? The law, medicine, something else.
00:04:00of
00:04:30a
00:04:46Asking follow-up questions leads to more balanced responses
00:04:49of and helps build trust, especially among professionals. A
00:04:53study found that doctors, for example, often remain cautious about
00:04:57AI. That's because experts can sometimes. underestimate what
00:05:01the technology is actually able to do:
00:05:05the 83
00:05:05at duesberg has been closed after an Antonov aircraft made emergency landing,
00:05:09fortunately no one was injured. AI deep fakes like
00:05:13these have become very convincing in recent years and as computing power
00:05:17continues to grow, they're getting even more realistic. the same goes for
00:05:21deep fakes circulating on the dark web, but is that really
00:05:24innovation? just because something's new doesn't make it
00:05:28innovation, there has to be value in it. for example, find
00:05:32it very difficult to see deep fake sexualized images of children as
00:05:36innovation, it may be technically new, but it's not an
00:06:12we ask AI a question: behind every answer is vast
00:06:16network of computers housed in massive, highly secure
00:06:20facilities protected from dust and
00:06:23heat, and nowhere has more them than northern Virginia
00:06:27in the U.S., just next to Washington DC. They
00:06:30take up enormous amounts of space, consume huge amounts of
00:06:34electricity, and they're not just an eyesore,
00:06:38they're pretty noisy too.
00:06:44"when Greg Pirio first stepped outside the home he just bought in
00:06:482012, he was surrounded by greenery, but where there was
00:06:52once a forest, there's now data
00:06:54center. It's really frustrating, we you
00:06:58know uh, how they how they could have voted to change the
00:07:02zoning to allow this so close to a neighborhood is beyond my
00:07:06uh comprehension. It's not just the view that's
00:07:09changed, the soundscape has too.
00:07:14'It's just such annoying sound
00:07:18of angry because
00:07:21uh uh it will reduce the prop the value of our properties
00:07:24here uh angry because uh it's chased the
00:07:28wild life away from us. The
00:07:31area in northern Virginia has become a global hub for data centers where the
00:07:35information that powers giant companies such as Uber, Netflix and
00:07:39Amazon as well as from AI applications is stored'. and
00:07:42processed. AI data centers in particular, require
00:07:46enormous amounts of electricity. These are
00:07:50data centers, look that direction, that direction, behind us, all
00:07:54three sides. Elena Schlussberg is also
00:07:57frustrated. At Virginia's more than 600 data
00:08:01centers, 260 are concentrated in just two residential
00:08:04communities. In the 1990s, the area was home to
00:08:08AOL, America's first major internet service provider.
00:08:12Today it's at the heart the AI boom. Look, see another
00:08:16American flag. We're all a part of American when we're building
00:08:19out uh, the wealthiest industry in the world and paying for their
00:08:23infrastructure. Northern Virginia leads the world in data
00:08:27center concentration, accounting for 14% of all data
00:08:31centers globally. Running those facilities
00:08:34doesn't require many workers, but it does consume vast amounts of
00:08:38electricity. And that's having an impact on.
00:08:42residents communities are in direct
00:08:45competition with industry that has
00:08:48an unprecedented need for power and water, and
00:08:52so those things that you normally rely on your affordable, clean
00:08:55energy is now being consumed by
00:08:59this one customer, and that's why you see
00:09:03your utility bills increasing. electricity prices here have
00:09:07risen by 30% in just 5 years. the enormous
00:09:10demand for energy is one. downside the AI
00:09:13boom, so it looked as though it was a matter of economic
00:09:17development and a good thing for the community, but they did not think
00:09:21through the implications for the ordinary rate payer.
00:09:25industry often needs a certain amount of power, but it
00:09:29tends to be distributed and the increases are
00:09:32predictable and measurable. there's almost nothing
00:09:36that compares to this in the past, but there are locals
00:09:40who are benefiting, some residents. have joined forces to sell
00:09:43farmland for the construction of data centers and power
00:09:46plants. mine has been the family
00:09:50farm for generations and
00:09:53unfortunately my kids and grandchildren have
00:09:57absolutely no interest in and we came up with a win win
00:10:00solution, the county's going to make money, the
00:10:04um, which helps them pay other people, all their employees,
00:10:08more money, get better parks, get better schools for everyone, and yes we're going to...
00:10:12money: data centers generate more than 1 billion dollars in
00:10:16tax revenue every year and construction continues around the
00:10:20clock, but that growth comes a cost, depending its
00:10:24capacity, single AI data center can consume as much
00:10:27electricity as an entire
00:10:29city. keeping
00:10:33buildings cool already accounts for more than 10% of
00:10:36global electricity consumption and demand is only expected to
00:10:40rise. researchers think they may have found a way to
00:10:44dramatically reduce the energy needs for air conditioners. they're
00:10:48developing new cooling technology that uses special metals
00:10:52that heat up when stretched and cool down again when...
00:10:55least: only enough room for a single
00:10:59soda can, but this mini refrigerator is packed with innovative
00:11:02technology. researchers at Zarland University in
00:11:06Southwest Germany have built it to demonstrate a new calling method that could
00:11:10be more energy efficient and
00:11:12climate-friendly.
00:11:19That means lower energy consumption overall, which ultimately means lower
00:11:23CO2 emissions globally. This
00:11:26cooling system uses very little electricity and doesn't require
00:11:30environmentally harmful or flammable refrigerants, but
00:11:33how? The key lies in bundles of fine
00:11:37wires, a bit like artificial muscles that rotate around the cooling
00:11:40chamber. They're made from a shape memory alloy,
00:11:44material engineered to return to a preset shape after being
00:11:48deformed.
00:11:50Paul Motski is a professor of smart material systems at Zarland
00:11:53University. He us is infrared camera to show us what's
00:11:57happening. the thermal image reveals the hidden superpower
00:12:00the nickel titanium wires under tension. it's the same
00:12:04phenomenon seen a balloon, a phase
00:12:06transformation. the atoms arrange themselves
00:12:10differently depending on the temperature and the mechanical stress in the
00:12:13material. so when i stretch this bundle of wires, i force it into
00:12:17different phase. the atoms reorganize
00:12:20themselves. that creates a different energy state, heat is
00:12:23released and the material. warms up, when i release the tension,
00:12:27the atoms rearrange themselves again, we get different energy state,
00:12:31heat is absorbed and the bundle cools down again. this is known as an
00:12:35elastocaloric effect. it can create temperature differences of up
00:12:39to 40 degrees celsius within the material. the phenomenon
00:12:43is well known, but only recently have researchers tried to harness it for
00:12:47use in refrigerators and heat
00:12:48pumps.
00:12:53how do we transfer the heat? and cold that we generate to where it's actually
00:12:57needed. a fridge we need to bring the cooling into the interior and
00:13:01release the heat into the surroundings.
00:13:05here circulating air passes over the cooled wires, then flows
00:13:08round the cooling chamber circled in blue, causing the contents inside to
00:13:12cool down too. the team from Zarbrukan demonstrates the
00:13:16technology with this mini refrigerator at trade shows and
00:13:19conferences. however, its compact design limits its cooling
00:13:23performance, drinks and... can only be cooled to about 12 degrees
00:13:27celsius. The team has also developed more powerful
00:13:31prototypes with cooling capacities of up to 250 watts,
00:13:35roughly what an average fridge needs. But in computer
00:13:38simulations, electricity consumption is about half that of
00:13:42comparable conventional systems. The technology is
00:13:46slowly gaining momentum. Startups around the world are
00:13:49developing caloric heat pumps and refrigerators. Both the European
00:13:53commission and the
00:13:54US department. of energy see enormous potential, air
00:13:58conditioners are becoming more common in households around the world,
00:14:01in India for example, and they consume huge
00:14:05amounts of energy. the world's roughly 1.6 billion air
00:14:09conditioning units account for around 30% of global electricity
00:14:13consumption, according to estimates from the international energy
00:14:16agency. that figure has at least tripled since
00:14:191990. researchers at the center for
00:14:23mechatronics and automation
00:14:24klimaerwärmung
00:14:55different weiter voranschreiten zu lassen,
00:14:56but that goal is
00:14:58still a long way off. for now, the latest prototype
00:15:03challenge: tackling the is nickel titanium wire bundles wear out over
00:15:07time. depending on the alloy and the amount of force applied,
00:15:11they can withstand anywhere from tens of thousands to hundreds of thousands of
00:15:14cycles. the new replacement cartridge makes swapping them out
00:15:18relatively easy. in this case, just 28 grams of nickel
00:15:22titanium wire provide roughly 100 watts.
00:15:37and releases into the room without causing any
00:15:39problems. The Zarbrook team believes its cooling
00:15:43systems could find a market in niche applications such as lab
00:15:47equipment. They believe the technology could be ready within two to
00:15:51three years, but they estimate
00:15:53it will be at least another decade before consumers can start replacing
00:15:57conventional refrigerators with elasto-caloric
00:16:00systems. As
00:16:03temperatures rise around the world, so does the risk of wild fire?
00:16:37narrations and I hope I make the right
00:16:39decisions.
00:16:44If the decision is wrong, I have to make expensive changes, rebuild and basically
00:16:48start all over again. To create the forest the
00:16:51future, you first need a lot of information about its current
00:16:54condition. A research team at Anhalt University of Applied
00:16:58Sciences and Central Germany is developing an app that allows
00:17:02anyone walking in the woods to share their
00:17:04observations. Da wird einem
00:17:08hier angezeigt, the app tells you to hold your smartphone horizontally, and then you
00:17:11take three photos. First, it says here, take
00:17:15picture angled up into the tree canopy, then it tells
00:17:19me to take a second photo straight ahead into the forest, and a third
00:17:23one angled down towards the ground. After that, I can share
00:17:27my location and upload the images. Photos
00:17:31taken by forest visitors are a real treasure trove of data, say the
00:17:35researchers. Every
00:17:38measurement, every piece of information helps.
00:17:42They've discovered a medium-sized fallen deadwood log, heavily
00:17:45decomposed, even that will be recorded.
00:17:49The data is meant to provide the foundation for a completely new
00:17:53approach. We're developing an AI
00:17:56model and investigating whether AI can assess the condition of a forest
00:18:00based on photograph. What
00:18:04special is that anyone can take part? As
00:18:07citizen scientists, volunteers use the app to take photos on
00:18:11their walks. The project is called
00:18:15Minervalt car E, meaning my forest
00:18:18AI. The
00:18:21researchers trained the AI model behind the app, using more than
00:18:256,00 their own photos from two
00:18:27forests. The next step is to
00:18:31encourage enough citizen scientists to take
00:18:33part. The first version the...
00:18:37my Forest AI app is already available for Android. It should
00:18:41provide invaluable insights about the forest's current
00:18:44conditions. But many forest owners need to make changes
00:18:48now, like here in Munich. They need to know which tree species can
00:18:52best withstand heat, drought and pests. And these are big
00:18:55decisions: replacing the ecological benefits of a single mature
00:18:59tree, like water storage and carbon capture can require up to
00:19:03400 young trees a cost of up to €25,00 euros per
00:19:07hectare.
00:19:37is one of two and a half million forest owners without a dedicated
00:19:40forester. That's why he founded a startup called Arbero.
00:19:44Using software and AI, he calculates which tree species can best
00:19:48survive in specific locations. To do that, he purchases
00:19:52data, including from the European space
00:19:54agency. The app
00:19:58combines factors from a wide range of data: how
00:20:01acidic is the soil? Is location expected to receive lot
00:20:05of rainfall or very little? how
00:20:09much sunshine and frost is there, how are
00:20:12temperatures changing, and is the terrain flat or
00:20:16mountainous? all of this is mapped with precision down to just
00:20:20few square meters, using data from the year 2000, up to
00:20:23now. the platform shows which the existing
00:20:27tree species is most suitable, both today and in projections
00:20:31extending to the year 2100. i can also change the mix
00:20:35of tree species and see exactly.
00:20:50After the outbreak, many beetle-infested trees had to be felled and
00:20:53removed, leaving large stretches almost empty of
00:20:56trees. The
00:21:00losses were substantial. In the future, the digital forester he
00:21:04created will hopefully reduce that risk. But these
00:21:08AI supported systems won't make decisions for people, nor will they
00:21:11replace forsters. Instead, they provide information to support
00:21:15reforestation planning, and that's becoming increasingly
00:21:19important. "if you have
00:21:23dry spell in spring and go six weeks without rain, what you've
00:21:27planted for the season goes to waste, then we have to replant
00:21:30in those situations we have losses of up to 50 to
00:21:3460%. the forest the future will
00:21:38look different to those we know today. experts envision something like
00:21:42this: uniform monocultures such as spruce
00:21:46forests will be replaced by mixed forests made up of deciduous and..."
00:21:50forest trees of different ages and heights. This creates
00:21:53distinct forest layers, the canopy, middle layer and
00:21:56undergrowth. Light and shade alternate across the forest floor,
00:22:00encouraging different layers of growth. Sustainability will also play
00:22:04a role: only individual trees will be removed, a process
00:22:08known as group selection harvesting. The
00:22:11gaps allow the forest to regenerate without losing its cool,
00:22:15moist microclimate. Ganz am Anfang
00:22:19steht. with a single decision, which tree and where, which
00:22:23species i putting my faith in? it's difficult, but we have
00:22:27access to huge amount of data and we should make use of it, and man
00:22:31sollte das eben auch. in the future, data will also
00:22:34come from citizen scientists, and everyone who contributes gets a
00:22:38little something in
00:22:39return.
00:22:44immer dann, when someone uploads a contribution, they receive
00:22:48a thank you message. because we're grateful for every submission from the
00:22:52public, they also receive some information about the
00:22:55forests. building the forest the future
00:22:59means making decisions today that will affect generations to
00:23:02come. no one knows exactly what these forests will look like a
00:23:06hundred years, but the process of creating them has already
00:23:10begun.
