#433474 How to Feed Global Demand for ...
“You really can’t justify tuna in Chicago as a source of sustenance.” That’s according to Dr. Sylvia Earle, a National Geographic Society Explorer who was the first female chief scientist at NOAA. She came to the Good Food Institute’s Good Food Conference to deliver a call to action around global food security, agriculture, environmental protection, and the future of consumer choice.
It seems like all options should be on the table to feed an exploding population threatened by climate change. But Dr. Earle, who is faculty at Singularity University, drew a sharp distinction between seafood for sustenance versus seafood as a choice. “There is this widespread claim that we must take large numbers of wildlife from the sea in order to have food security.”
A few minutes later, Dr. Earle directly addressed those of us in the audience. “We know the value of a dead fish,” she said. That’s market price. “But what is the value of a live fish in the ocean?”
That’s when my mind blew open. What is the value—or put another way, the cost—of using the ocean as a major source of protein for humans? How do you put a number on that? Are we talking about dollars and cents, or about something far larger?
Dr. Liz Specht of the Good Food Institute drew the audience’s attention to a strange imbalance. Currently, about half of the yearly global catch of seafood comes from aquaculture. That means that the other half is wild caught. It’s hard to imagine half of your meat coming directly from the forests and the plains, isn’t it? And yet half of the world’s seafood comes from direct harvesting of the oceans, by way of massive overfishing, a terrible toll from bycatch, a widespread lack of regulation and enforcement, and even human rights violations such as slavery.
The search for solutions is on, from both within the fishing industry and from external agencies such as governments and philanthropists. Could there be another way?
Makers of plant-based seafood and clean seafood think they know how to feed the global demand for seafood without harming the ocean. These companies are part of a larger movement harnessing technology to reduce our reliance on wild and domesticated animals—and all the environmental, economic, and ethical issues that come with it.
Producers of plant-based seafood (20 or so currently) are working to capture the taste, texture, and nutrition of conventional seafood without the limitations of geography or the health of a local marine population. Like with plant-based meat, makers of plant-based seafood are harnessing food science and advances in chemistry, biology, and engineering to make great food. The industry’s strategy? Start with what the consumer wants, and then figure out how to achieve that great taste through technology.
So how does plant-based seafood taste? Pretty good, as it turns out. (The biggest benefit of a food-oriented conference is that your mouth is always full!)
I sampled “tuna” salad made from Good Catch Food’s fish-free tuna, which is sourced from legumes; the texture was nearly indistinguishable from that of flaked albacore tuna, and there was no lingering fishy taste to overpower my next bite. In a blind taste test, I probably wouldn’t have known that I was eating a plant-based seafood alternative. Next I reached for Ocean Hugger Food’s Ahimi, a tomato-based alternative to raw tuna. I adore Hawaiian poke, so I was pleasantly surprised when my Ahimi-based poke captured the bite of ahi tuna. It wasn’t quite as delightfully fatty as raw tuna, but with wild tuna populations struggling to recover from a 97% decline in numbers from 40 years ago, Ahimi is a giant stride in the right direction.
These plant-based alternatives aren’t the only game in town, however.
The clean meat industry, which has also been called “cultured meat” or “cellular agriculture,” isn’t seeking to lure consumers away from animal protein. Instead, cells are sampled from live animals and grown in bioreactors—meaning that no animal is slaughtered to produce real meat.
Clean seafood is poised to piggyback off platforms developed for clean meat; growing fish cells in the lab should rely on the same processes as growing meat cells. I know of four companies currently focusing on seafood (Finless Foods, Wild Type, BlueNalu, and Seafuture Sustainable Biotech), and a few more are likely to emerge from stealth mode soon.
Importantly, there’s likely not much difference between growing clean seafood from the top or the bottom of the food chain. Tuna, for example, are top predators that must grow for at least 10 years before they’re suitable as food. Each year, a tuna consumes thousands of pounds of other fish, shellfish, and plankton. That “long tail of groceries,” said Dr. Earle, “is a pretty expensive choice.” Excitingly, clean tuna would “level the trophic playing field,” as Dr. Specht pointed out.
All this is only the beginning of what might be possible.
Combining synthetic biology with clean meat and seafood means that future products could be personalized for individual taste preferences or health needs, by reprogramming the DNA of the cells in the lab. Industries such as bioremediation and biofuels likely have a lot to teach us about sourcing new ingredients and flavors from algae and marine plants. By harnessing rapid advances in automation, robotics, sensors, machine vision, and other big-data analytics, the manufacturing and supply chains for clean seafood could be remarkably safe and robust. Clean seafood would be just that: clean, without pathogens, parasites, or the plastic threatening to fill our oceans, meaning that you could enjoy it raw.
What about price? Dr. Mark Post, a pioneer in clean meat who is also faculty at Singularity University, estimated that 80% of clean-meat production costs come from the expensive medium in which cells are grown—and some ingredients in the medium are themselves sourced from animals, which misses the point of clean meat. Plus, to grow a whole cut of food, like a fish fillet, the cells need to be coaxed into a complex 3D structure with various cell types like muscle cells and fat cells. These two technical challenges must be solved before clean meat and seafood give consumers the experience they want, at the price they want.
In this respect clean seafood has an unusual edge. Most of what we know about growing animal cells in the lab comes from the research and biomedical industries (from tissue engineering, for example)—but growing cells to replace an organ has different constraints than growing cells for food. The link between clean seafood and biomedicine is less direct, empowering innovators to throw out dogma and find novel reagents, protocols, and equipment to grow seafood that captures the tastes, textures, smells, and overall experience of dining by the ocean.
Asked to predict when we’ll be seeing clean seafood in the grocery store, Lou Cooperhouse the CEO of BlueNalu, explained that the challenges aren’t only in the lab: marketing, sales, distribution, and communication with consumers are all critical. As Niya Gupta, the founder of Fork & Goode, said, “The question isn’t ‘can we do it’, but ‘can we sell it’?”
The good news is that the clean meat and seafood industry is highly collaborative; there are at least two dozen companies in the space, and they’re all talking to each other. “This is an ecosystem,” said Dr. Uma Valeti, the co-founder of Memphis Meats. “We’re not competing with each other.” It will likely be at least a decade before science, business, and regulation enable clean meat and seafood to routinely appear on restaurant menus, let alone market shelves.
Until then, think carefully about your food choices. Meditate on Dr. Earle’s question: “What is the real cost of that piece of halibut?” Or chew on this from Dr. Ricardo San Martin, of the Sutardja Center at the University of California, Berkeley: “Food is a system of meanings, not an object.” What are you saying when you choose your food, about your priorities and your values and how you want the future to look? Do you think about animal welfare? Most ethical regulations don’t extend to marine life, and if you don’t think that ocean creatures feel pain, consider the lobster.
Seafood is largely an acquired taste, since most of us don’t live near the water. Imagine a future in which children grow up loving the taste of delicious seafood but without hurting a living animal, the ocean, or the global environment.
Do more than imagine. As Dr. Earle urged us, “Convince the public at large that this is a really cool idea.”

#433301 ‘Happiness Tech’ Is On the Rise. Is ...
We often get so fixated on technological progress that we forget it’s merely one component of the entirety of human progress. Technological advancement does not necessarily correlate with increases in human mental well-being.
While cleaner energy, access to education, and higher employment rates can improve quality of life, they do not guarantee happiness and inner peace. Amid what appears to be an increasing abundance of resources and ongoing human progress, we are experiencing a mental health epidemic, with high anxiety and depression rates. This is especially true in the developed world, where we have access to luxuries our ancestors couldn’t even dream of—all the world’s information contained in a device we hold in the palm of our hands, for example.
But as you may have realized through your own experience, technology can make us feel worse instead of better. Social media can become a tool for comparison and a source of debilitating status anxiety. Increased access to goods and services, along with the rise of consumerism, can lead people to choose “stuff” over true sources of meaning and get trapped in a hedonistic treadmill of materialism. Tools like artificial intelligence and big data could lead to violation of our privacy and autonomy. The digital world can take us away from the beauty of the present moment.
Understanding Happiness
How we use technology can significantly impact our happiness. In this context, “happiness” refers to a general sense of well-being, gratitude, and inner peace. Even with such a simple definition, it is a state of mind many people will admit they lack.
Eastern philosophies have told us for thousands of years that the problem of human suffering begins with our thoughts and perceptions of the circumstances we are in, as opposed to beginning with the circumstances themselves. As Derren Brown brilliantly points out in Happy: Why More or Less Everything Is Absolutely Fine, “The problem with the modern conception of happiness is that it is seen as some kind of commodity. There is this fantasy that simply by believing in yourself and setting goals you can have anything. But that simply isn’t how life works. The ancients had a much better view of it. They offered an approach of not trying to control things you can’t control, and of lessening your desires and your expectations so you achieve a harmony between what you desire and what you have.”
A core part of feeling more happy is about re-wiring our minds to adjust our expectations, exercise gratitude, escape negative narratives, and live in the present moment.
But can technology help us do that?
Applications for Mental Well-Being
Many doers are asking themselves how they can leverage digital tools to contribute to human happiness.
Meditation and mindfulness are examples of practices we can use to escape the often overwhelming burden of our thoughts and ground our minds into the present. They have become increasingly democratized with the rise of meditation mobile apps, such as Headspace, Gaia, and Calm, that allow millions of people globally to use their phones to learn from experts at a very low cost.
These companies have also partnered with hospitals, airlines, athletic teams, and others that could benefit from increased access to mindfulness and meditation. The popularity of these apps continues to rise as more people recognize their necessity. The combination of mass technology and ancient wisdom is one that can lead to a transformation of the collective consciousness.
Sometimes merely reflecting on the sources of joy in our lives and practicing gratitude can contribute to better well-being. Apps such as Happier encourage users to reflect upon and share pleasant everyday moments in their daily lives. Such exercises are based on the understanding that being happy is a “skill” one can build though practice and through scientifically-proven activities, such as writing down a nice thought and sharing your positivity with the world. Many other tools such as Track Your Happiness and Happstr allow users to track their happiness, which often serves as a valuable source of data to researchers.
There is also a growing body of knowledge that tells us we can achieve happiness by helping others. This “helper’s high” is a result of our brains producing endorphins after having a positive impact on the lives of others. In many shapes and forms, technology has made it easier now more than ever to help other people no matter where they are located. From charitable donations to the rise of social impact organizations, there is an abundance of projects that leverage technology to positively impact individual lives. Platforms like GoVolunteer connect nonprofits with individuals from a variety of skill sets who are looking to gift their abilities to those in need. Kiva allows for fundraising loans that can change lives. These are just a handful of examples of a much wider positive paradigm shift.
The Future of Technology for Well-Being
There is no denying that increasingly powerful and immersive technology can be used to better or worsen the human condition. Today’s leaders will not only have to focus on their ability to use technology to solve a problem or generate greater revenue; they will have to ask themselves if their tech solutions are beneficial or detrimental to human well-being. They will also have to remember that more powerful technology does not always translate to happier users. It is also crucial that future generations be equipped with the values required to use increasingly powerful tools responsibly and ethically.
In the Education 2030 report, the Millennium Project envisions a world wherein portable intelligent devices combined with integrated systems for lifelong learning contribute to better well-being. In this vision, “continuous evaluation of individual learning processes designed to prevent people from growing unstable and/or becoming mentally ill, along with programs aimed at eliminating prejudice and hate, could bring about a more beautiful, loving world.”
There is exciting potential for technology to be leveraged to contribute to human happiness at a massive scale. Yet, technology shouldn’t consume every aspect of our lives, since a life worth living is often about balance. Sometimes, even if just for a few moments, what would make us feel happier is we disconnected from technology to begin with.

#433288 The New AI Tech Turning Heads in Video ...
A new technique using artificial intelligence to manipulate video content gives new meaning to the expression “talking head.”
An international team of researchers showcased the latest advancement in synthesizing facial expressions—including mouth, eyes, eyebrows, and even head position—in video at this month’s 2018 SIGGRAPH, a conference on innovations in computer graphics, animation, virtual reality, and other forms of digital wizardry.
The project is called Deep Video Portraits. It relies on a type of AI called generative adversarial networks (GANs) to modify a “target” actor based on the facial and head movement of a “source” actor. As the name implies, GANs pit two opposing neural networks against one another to create a realistic talking head, right down to the sneer or raised eyebrow.
In this case, the adversaries are actually working together: One neural network generates content, while the other rejects or approves each effort. The back-and-forth interplay between the two eventually produces a realistic result that can easily fool the human eye, including reproducing a static scene behind the head as it bobs back and forth.
The researchers say the technique can be used by the film industry for a variety of purposes, from editing facial expressions of actors for matching dubbed voices to repositioning an actor’s head in post-production. AI can not only produce highly realistic results, but much quicker ones compared to the manual processes used today, according to the researchers. You can read the full paper of their work here.
“Deep Video Portraits shows how such a visual effect could be created with less effort in the future,” said Christian Richardt, from the University of Bath’s motion capture research center CAMERA, in a press release. “With our approach, even the positioning of an actor’s head and their facial expression could be easily edited to change camera angles or subtly change the framing of a scene to tell the story better.”
AI Tech Different Than So-Called “Deepfakes”
The work is far from the first to employ AI to manipulate video and audio. At last year’s SIGGRAPH conference, researchers from the University of Washington showcased their work using algorithms that inserted audio recordings from a person in one instance into a separate video of the same person in a different context.
In this case, they “faked” a video using a speech from former President Barack Obama addressing a mass shooting incident during his presidency. The AI-doctored video injects the audio into an unrelated video of the president while also blending the facial and mouth movements, creating a pretty credible job of lip synching.
A previous paper by many of the same scientists on the Deep Video Portraits project detailed how they were first able to manipulate a video in real time of a talking head (in this case, actor and former California governor Arnold Schwarzenegger). The Face2Face system pulled off this bit of digital trickery using a depth-sensing camera that tracked the facial expressions of an Asian female source actor.
A less sophisticated method of swapping faces using a machine learning software dubbed FakeApp emerged earlier this year. Predictably, the tech—requiring numerous photos of the source actor in order to train the neural network—was used for more juvenile pursuits, such as injecting a person’s face onto a porn star.
The application gave rise to the term “deepfakes,” which is now used somewhat ubiquitously to describe all such instances of AI-manipulated video—much to the chagrin of some of the researchers involved in more legitimate uses.
Fighting AI-Created Video Forgeries
However, the researchers are keenly aware that their work—intended for benign uses such as in the film industry or even to correct gaze and head positions for more natural interactions through video teleconferencing—could be used for nefarious purposes. Fake news is the most obvious concern.
“With ever-improving video editing technology, we must also start being more critical about the video content we consume every day, especially if there is no proof of origin,” said Michael Zollhöfer, a visiting assistant professor at Stanford University and member of the Deep Video Portraits team, in the press release.
Toward that end, the research team is training the same adversarial neural networks to spot video forgeries. They also strongly recommend that developers clearly watermark videos that are edited through AI or otherwise, and denote clearly what part and element of the scene was modified.
To catch less ethical users, the US Department of Defense, through the Defense Advanced Research Projects Agency (DARPA), is supporting a program called Media Forensics. This latest DARPA challenge enlists researchers to develop technologies to automatically assess the integrity of an image or video, as part of an end-to-end media forensics platform.
The DARPA official in charge of the program, Matthew Turek, did tell MIT Technology Review that so far the program has “discovered subtle cues in current GAN-manipulated images and videos that allow us to detect the presence of alterations.” In one reported example, researchers have targeted eyes, which rarely blink in the case of “deepfakes” like those created by FakeApp, because the AI is trained on still pictures. That method would seem to be less effective to spot the sort of forgeries created by Deep Video Portraits, which appears to flawlessly match the entire facial and head movements between the source and target actors.
“We believe that the field of digital forensics should and will receive a lot more attention in the future to develop approaches that can automatically prove the authenticity of a video clip,” Zollhöfer said. “This will lead to ever-better approaches that can spot such modifications even if we humans might not be able to spot them with our own eyes.
