United Airlines has announced what it says is its largest transatlantic expansion in its history. The airline will launch five new destinations and 10 new routes by spring 2022. United says the destinations are not served by any other carrier in North America.

Here’s the full list of totally new destinations that you can hop to on a United flight to come next year. These will begin in spring 2022:

• Amman, Jordan
• Bergen, Norway
• Azores, Portugal
• Palma de Mallorca, Spain
• Tenerife, Spanish Canary Islands

And here’s the list of new routes United is adding come next spring from select U.S. cities:

• Berlin
• Dublin
• Frankfurt
• Milan
• Munich
• Nice, France
• Rome
• Zurich
• Bangalore, India
• Tokyo

United’s expansion in transatlantic flights shows a healthy dose of optimism that international travel will pick up next year after being destroyed in 2020 by the pandemic and seeing relatively sparse activity compared to historical trends in 2021.

Announcing the transatlantic expansion, Patrick Quayle, senior vice president of international network and alliances at United, said, “given our big expectations for a rebound in travel to Europe for summer, this is the right time to leverage our leading global network in new, exciting ways. Our expansion offers the widest range of destinations to discover—introducing new, trendy locales that our customers will love, as well as adding more flights to iconic, popular cities.”

Each of its carbon-sucking units is the size of a shipping container, yet the world’s largest direct air capture machine—the Orca plant in Iceland—captures and stores only about 4,000 tonnes of CO₂ a year. That’s about three seconds’ worth of global emissions.

Still, the Intergovernmental Panel on Climate Change reports that technologies that remove CO₂ from the air like this will be needed alongside deep cuts in emissions to reduce global warming. In fact, climate scientists modeling pathways for stabilizing warming at 1.5°C (the goal of the Paris agreement) assume that a carbon removal industry based around one method may need to be around 40% the size of the current fossil fuel industry.

There are several ways to remove carbon from the atmosphere. One is called bioenergy with carbon capture and storage, or Beccs. Here, vast acres of fast-growing plants are grown and then harvested and burned to generate electricity or make biofuel for vehicles. Beccs can even use waste from farms or timber plantations. The carbon normally released during the burning or fermentation stage is instead captured and pumped underground in old oil and gas wells or deep rock formations called saline aquifers. These storage sites can be beneath land (which is common in the U.S.) or the seabed. There are more than 20 years of experience in storing CO₂ under the Norwegian North Sea, for instance.

Attempts to calculate how much carbon removal is possible often address how much it will cost, or how much carbon can realistically be extracted from the atmosphere. This can be done by assessing the land area available to produce biomass crops, or the size of underground reservoirs for storing the gas.

But what scientists often overlook when predicting the future capacity of these technologies is how society will need to change to accommodate them. For instance, what will a sudden change to how land is used mean for communities and livelihoods? How can increasing demand for land to grow food or restore habitat be reconciled with the need to produce lots of biomass for Beccs? And who should even be able to make these decisions for them to be considered fair and ethical?

If world leaders at the UN climate summit in Glasgow fail to address these questions, they run the risk of making overly optimistic judgments about how much CO₂ it’s possible to remove. If it transpires that the international community cannot rely on these technologies as much as climate modeling suggests we need to, then society will need to decarbonize even faster to prevent catastrophic climate change.

Social and political issues matter

There is only one demonstration Beccs project operating in the world today, in Illinois. Alongside other researchers, we talked to experts working in sectors like forestry and energy to understand what’s needed to bring this new industry to life.

These experts are aware of large-scale bioenergy projects, such as those cultivating sugar cane ethanol in Brazil, which have deprived local people of land and destroyed native habitat. Many of them worry that a global Beccs industry that developed from these practices would exacerbate inequality by, for example, reducing access to food and ultimately fail to remove carbon from the atmosphere by actually increasing deforestation. The U.K.’s largest power plant for generating energy from biomass, Drax, mostly imports wood chips from North America, while U.K. farmers grow grass for use in a handful of smaller-scale power plants. But as the U.K. develops a Beccs industry, rising demand for bioenergy could mean the cheapest and most exploitative sources win out.

The experts were also unsure about whether there is even enough free land to accommodate expanding bioenergy crops. Many voiced concerns about the consequences for the rights of people living in and working on land that is earmarked for Beccs.

Some experts doubted there was sufficient political support—capable of transcending short-term electoral cycles—to pull off the necessary innovation to build carbon capture and storage capacity in the U.K. This technology is needed not just for Beccs but also to decarbonize heavy industry, including steel manufacturing and chemicals.

We found that these social and political obstacles were rarely represented, if at all, in models of the global potential for carbon removal. Of course, some of these things can’t be modeled. Models aren’t usually designed to incorporate the nuances of decision-making at national, regional, and local levels, or the importance of cultural and spiritual values that people endow landscapes.

World leaders need a more complete picture of the complexity we know exists in the real world before embarking on the construction of a global carbon removal industry. Making this happen is as much a question of who pays to remove the carbon and who has a say in how the land is managed, as details about technology. If the political and social limitations are not better understood, then it is hard to imagine how these carbon removal pipe dreams will get off the ground.

Facebook says it’s designing a pair of augmented reality glasses that can add digital content to the world in front of us. They might be years away from shipping. And to be useful to us—to walk us through a pizza recipe or help us find the car keys—they need to offer a built-in assistant with some serious AI smarts. The challenge is getting enough video footage—shot from the perspective of the user—to train the assistant to make inferences about the world as seen through the lenses of the glasses.

That kind of first-person training video is scarce. So Facebook partnered with 13 universities to create a large new data set of “egocentric” training video called Ego4D. The universities recruited a total of 855 people in nine countries to strap on GoPro cameras to collect the video. In all, participants captured 3,025 hours of first-person video from their everyday lives.

The new data set will help Facebook researchers begin the process of creating and training an AI assistant to understand how users interact with other people, objects, and the environment around them. The AI, Facebook says, will be trained to recall things a user has seen or heard in the past to help with present activities, and to anticipate things the user might need in the future.

Facebook has boiled those general concepts down into five more-specific AI tasks, which hint at how the company sees its future AR glasses being useful. Facebook’s lead researcher on the Ego4D project, Kristen Grauman, told me the tasks were chosen based on how well they “span the fundamentals needed to build any or many applications.”

[Image: courtesy of Facebook]“Episodic memory” simply allows an assistant to recall something recorded by the glasses in the past. For instance, the AI assistant might recall and display the location of a lost item such as a set of keys. It might even display within the glasses the actual footage of the user placing the item in a certain location.

[Image: courtesy of Facebook]“Forecasting” analyzes a present activity and then suggests what the user might or should do next. It might suggest the next step in a recipe, for example.

[Image: courtesy of Facebook]“Object manipulation” might analyze how a user is handling an object, and make suggestions on how to do it better. For instance, the AI assistant might teach a percussion student how to hold drumsticks properly.

“Audio-visual conversation transcription” listens to social conversations the user has, and records them or transcribes them into text that could be recalled later. If you’re following a recipe, you might call up something your grandmother said in the past about a secret cooking tip, for example.

“Social interaction” adds a layer onto the audio-visual conversation transcription task, Grauman says, by detecting “who is looking at me and when, who’s paying attention to me, and who’s talking to me.”

Grauman says that the data set created by Facebook and its university partners contains anywhere from 50 to 800 hours of video footage for each of the use cases. Figuring out what it showed involved plenty of human labor: “Someone watched the video and every time something happened, [they] paused and wrote a sentence about it,” she says. The process yielded about 13 sentences per minute.

In all, the annotation job took a quarter of a million hours of work by professional labelers. But these annotations are vital for teaching the AI models to make inferences and recall things. “It’s really cool because it gives us the language-vision connection and it gives us a way to index the data from the get-go,” Grauman says.

The data set will lay the groundwork from which researchers can push the AI to understand a variety of everyday tasks the user might need help with. But training an AI model to classify and predict the universe of things, people, and situations a user might encounter during their day is a very big challenge, and Facebook has a long way to go toward producing a helpful and versatile assistant.

“The first real barrier is the data, so we’re taking a good crack at that through this contribution,” Grauman says. “But even with the data, now the fun begins in earnest as far as the core research challenges.”

When it comes to pregnancy and childbirth, the focus tends to be on the baby’s health. As a result, women don’t often get the support they need, as they experience radical physical and psychological changes during and after delivery. That’s partly why maternal mortality rates have been on the rise in the United States, increasing more than 15% in 2019 alone. And Black women are three times more likely than their white counterparts to die of pregnancy-related causes. Yet, nearly two-thirds of pregnancy-related deaths are preventable.

Four years ago, Kate Westervelt founded a startup called Mombox to give women tools and products that would help them as they recovered from labor and delivery. Now, she’s launching a new subscription kit that gives women science-backed support as they recover in the year after childbirth. Westervelt was inspired by a growing body of academic research about the intense transformation that women experience after giving birth.

Westervelt came up with the concept of Mombox after her own pregnancy, when she noticed that the medical system, and society more broadly, tended to focus on the needs of the baby rather than those of the mother. Companies now sell products like belly bands, which help with C-section recovery, and more comfortable mesh underwear. But products like this are often hard to find and come from a range of small brands. Westervelt’s idea was to scour the market for labor and delivery products and test and curate them, in order to spare women the time and effort required to do it themselves.

But Westervelt realized that a woman’s recovery from pregnancy takes far longer than her hospital stay or even the few weeks after she’s home with her newborn. “It’s a misconception that maternal mortality refers to dying during childbirth,” she says. “When a woman dies within a year of giving birth, that is counted toward the maternal mortality rate. And yet, women get hardly any support during this first year, besides a final checkup with their OBGYN six weeks after delivering.”

[Screenshot: Mombox]With the new offering, Westervelt wants to provide tools for each month post-delivery to help with the physical recovery. For $99, customers can buy a single month’s box to focus on a problem like mood shifts or sleep. Or for $69 a month, they can sign up for the yearlong program, which will deliver boxed kits every month at the right postpartum stage. (There are also 3- and 6-month subscriptions.) Still, the subscription boxes aren’t cheap and will likely be out of reach for many lower-income women who would especially benefit from these kinds of products and resources.

Each box contains educational materials to help new mothers identify what’s considered “normal” and what might need medical attention. They also can include wellness and fitness products for help with common issues, such as the separation of abdominal muscles or weakening of the pelvic floor. Westervelt worked with a panel of researchers and practitioners to develop this content and curate products, including lactation consultants and perinatal physical therapists. And when possible, she sources products from small businesses owned by women and people of color. “Our priority is picking the best products on the market,” says Westervelt. “We’re also helping to support brands that specialize in creating these products by connecting with the women who need them.”

As she was developing these boxes, Westervelt was influenced by the research on “matrescence,” an anthropological term that refers to how a woman’s identity changes when she becomes a mother. It was coined in the 1970s by medical anthropologist Dana Raphael, but never really became widely known in mainstream culture. Over the last decade, Aurélie Athan, a reproductive psychologist at Columbia University, has been working to bring it back into the public consciousness. “It’s a concept that has parallels in adolescence, which is something that is widely understood in our culture,” says Westervelt. “We accept that when a child becomes an adult, their bodies change but so does their entire relationship to the world, and it’s a process of transformation that takes years. The same is actually true when a person gives birth. And yet we don’t seem to recognize that.”

In some ways, it’s not particularly surprising that matrescence hasn’t been rigorously studied. Researchers have documented a persistent gender bias in health care, in which doctors don’t treat women’s pain as seriously as men’s, and women’s health issues aren’t researched as thoroughly as men’s—including how pregnant women would respond to the COVID-19 vaccine. But Athan says things are slowly beginning to change. “There’s been growing awareness about postpartum depression and maternal mental health screening,” she says. “Then there was the #MeToo movement, where women insisted that people take their voices seriously.”

Athan believes that simply educating women—and society—about matrescence can be an important first step toward helping new mothers through this transition. “So much of the discourse about new mothers is about how they can bounce back physically or ‘return’ to work,” she says. “The concept of matrescence is that you don’t ever go back to who you were before. But with the right tools, women can adapt to their new identities and lives.”

And that’s become Westervelt’s goal as she’s developed these monthly offerings. In addition to addressing women’s physical health, the boxes include resources to help mothers negotiate tricky things like reestablishing sexual intimacy with their partner and understanding postpartum brain shifts as they return to work. “The goal is to empower new moms with the research, so they can take control of their lives after they have a baby,” she says. “They might not be able to return to who they were before, but with support, their new lives could be even better.”

I haven’t had a reason to yell in the morning since my boys were little. Those occurrences were more of this variety: “You’re going to be late for school!” “Get in the car!” or “Where are your shoes?” So, when I heard about a class that encourages you to start your day screaming, I was curious.

The platform, called Open, is an in-person and online mindfulness studio that includes breathwork, meditation, and yoga instruction. Some of the breathwork classes include screaming. I’ll admit, the classes weren’t what I expected—which is a good thing. I envisioned jumping right into a scream. Instead, you build up to it with several minutes of active breathing, crescendoing with a guttural yell.

While there are several options, the class I took lasts 20 minutes and includes rounds of breathing exercises. You take two quick inhale breaths in through your mouth—the first to fill air near your belly, and the second to the top of your chest near your heart. Then you release the air with one exhale, also through your mouth. The exercise is done in quick succession, which after a while made me feel tingly and lightheaded.

A round lasts about five minutes. At the end, you take a deep breath in and hold it for 10 seconds. Then you exhale and hold empty lungs for another 10 seconds. After the second round, the breath-holding lasts 20 seconds, and after the third round, you hold your breath for 30 seconds.

The screaming comes in after the last round of active breathing exercises. You take a deep inhale and then let out a scream. Repeat as many times as you want.

The class I took is led by Open breathworks instructor Ally Maz. “This type of class is what we call upregulating,” says Maz. “It lifts the heart rate and works on endurance for performance and mental clarity. It’s similar to [Dutch fitness guru] Wim Hof breathing exercises.”

Active breathwork can help you release stress at the beginning of your day and connect to your body. After the third morning taking the class, I started to feel more in control of my day.

But why the screaming?

Active upregulating breathwork is energizing. Screaming can help you get out emotions you may not know you’re holding.

“When we hold the classes in person, people will scream, and then they’ll either cry or laugh because it’s like, ‘Oh my God, I’ve been holding on to that thing,'” says Maz. “There’s a transformational moment. It can be scary to hear your voice, especially as a female because we’re not always in touch with our rage or have a lot of ways to use our voice in the world. We can be hard on ourselves and may be holding onto guilt or shame. Stuff starts bubbling up, and screaming is an energy release.”

I didn’t cry or laugh, but I did feel lighter after the scream. Eventually, I increased the number of times I screamed because it felt empowering.

Other forms of breathwork

Breathing—without the screaming—can also circumvent stress. I also used the platform to do quick classes that are designed to help calm you. “Downregulated breathwork practices slow the heart rate and help you recover, rest, and sleep better, which is also helpful for anyone struggling with anxiety or panic,” says Maz. “It’s all how you manipulate the breath. Different patterns have different outcomes.”

Maz calls this type of breathing a sigh of relief. Inhale through your nose, and exhale through your mouth. “That stimulates the vagus nerve, and it sets off a neurotransmitter that essentially goes to your heart and says, ‘Hey, heart, slow down,'” she says. “The breath shifts us from the fight or flight state back into parasympathetic, which is the rest and digest part of the nervous system. It helps open the lungs and reset the body. So many of us are sitting on our computers, typing, and not focusing on our breath.”

Breathwork is one of Open’s most popular types of classes, says founder Raed Khawaja. “You can actually discover a lot when you start to pay attention to how you breathe,” he says.

The more breathwork practice you do, the more you remember to take a deeper inhale, adds Maz. “I feel more at ease being in traffic, or when the stress response comes in,” she says. “I know if I can slow my breath down, I’ll slow my heart rate down, and stimulate my vagus nerve.”

I tend to be a breath holder, either when I’m feeling stressed or in deep focus with work. I don’t realize I’m doing it until I release the breath. Getting in tune with my breathing felt very foreign at first, but it’s definitely a valuable tool I can use on demand when I start to feel tension.

So, after taking classes for a week, will I keep up the screaming? Probably not every day. Maz screams weekly and says it helps her feel calmer in her life. This seems like a cadence I’ll try.

“I would call it a safe avenue to get that emotion out of your body,” says Maz. “Then it’s not coming out in road rage or at your partner or being suppressed with alcohol or numbed out through binge watching TV. It’s a really healthy way to get some of that emotion out of your body.”

Without much effort, you can find news every day that confirms—over and over—that we are in a climate emergency. Droughts, fires, floods, hurricanes, and heat waves are now happening with such frequency, it can be hard to remember which tragedy happened last, while the political reaction is, at best, muted—entirely incommensurate to the challenge at hand.

In the absence of a grand political solution, we are forced to nibble around the edges and hope that science and technology can make enough advances to mitigate the problem, to give more time for world governments to act on broad de-carbonization. There is no cause for techno-optimism: We will not invent a perpetual motion machine that can somehow eliminate all the carbon in a way that allows life to continue as is, all without pushing political and business leaders. At the same time, you don’t need to surrender to complete techno-pessimism because scientists, inventors, and entrepreneurs are making slow but steady advances in ways to replace the vital carbon in our economy with clean alternatives.

Forty years ago, solar and wind power were considered by some to be expensive boondoggles, only for the wealthy hobbyists, that would never make a difference at scale. Now—after decades of research and development—they’re the cheapest source of power we have. This list contains just a few of the recent advances that could be the next technology that can grow into part of a future, clean economy. Some of the items on this list will turn out to be too expensive, too hard to scale, too small in impact to matter. But others could become part of the solution. No one piece of technology will save us, but together many of them can be the building blocks that undergird the political solution we need. —Morgan Clendaniel

• Austin, Texas, just voted to spend $7 billion on a transportation revolution. The Texas capital will build a 31-station rail system, rapid bus routes, and bike lanes to get more people out of cars.

Solving food shortages and waste

• Everything you need to know about the booming business of fighting food waste. A new wave of companies is figuring out how to make new products from food that used to end up in the trash, from pulp popsicles to beer bread. Here are 20 to watch.

Cleaning the planet

• These drones will plant 40,000 trees in a month. By 2028, they’ll have planted 1 billion. We need to massively reforest the planet, in a very short period of time. Flash Forest’s drones can plant trees a lot faster than humans.
• This beach-cleaning robot sifts sand for the tiny plastics that humans miss. It’s hard to pick up all the plastic trash on beaches by hand. BeBot, a solar-powered robot, speeds up the process.
• This “sustainable infrastructure company” just raised $2 billion to build more clean tech. Generate Capital makes the often-costly upfront investments in sustainable projects—from solar panels to electric vehicles to food waste digesters—and then sells the services to other companies.
• Microplastics are in everything. What if they were biodegradable? Microplastics are used everywhere from laundry detergent to agriculture. Biotech startup Calyxia is making a new version of the tiny capsules that dissolve in nature.
