Britain, Norway and the United States join forces with businesses to protect tropical forests.

Britain, Norway and the United States said Thursday they would join forces with some of the world’s biggest companies in an effort to rally more than $1 billion for countries that can show they are lowering emissions by protecting tropical forests. The goal is to make intact forests more economically valuable than they would be if the land were cleared for timber and agriculture.

The initiative comes as the world loses acre after acre of forests to feed global demand for soy, palm oil, timber and cattle. Those forests, from Brazil to Indonesia, are essential to limiting the linked crises of climate change and a global biodiversity collapse. They are also home to Indigenous and other forest communities. Amazon, Nestlé, Unilever, GlaxoSmithKline and Salesforce are among the companies promising money for the new initiative, known as the LEAF Coalition.

Last year, despite the global downturn triggered by the pandemic, tropical deforestation was up 12 percent from 2019, collectively wiping out an area about the size of Switzerland. That destruction released about twice as much carbon dioxide into the atmosphere as cars in the United States emit annually.

“The LEAF Coalition is a groundbreaking example of the scale and type of collaboration that is needed to fight the climate crisis and achieve net-zero emissions globally by 2050,” John Kerry, President Biden’s senior climate envoy, said in a statement. “Bringing together government and privatesector resources is a necessary step in supporting the large-scale efforts that must be mobilized to halt deforestation and begin to restore tropical and subtropical forests.”

An existing global effort called REDD+ has struggled to attract sufficient investment and gotten mired in bureaucratic slowdowns. This initiative builds on it, bringing private capital to the table at the country or state level. Until now, companies have invested in forests more informally, sometimes supporting questionable projects that prompted accusations of corruption and “greenwashing,” when a company or brand portrays itself as an environmental steward but its true actions don’t support the claim.

The new initiative will use satellite imagery to verify results across wide areas to guard against those problems. Monitoring entire jurisdictions would, in theory, prevent governments from saving forestland in one place only to let it be cut down elsewhere.

Under the plan, countries, states or provinces with tropical forests would commit to reducing deforestation and degradation. Each year or two, they would submit their results, calculating the number of tons of carbon dioxide reduced by their efforts. An independent monitor would verify their claims using satellite images and other measures. Companies and governments would contribute to a pool of money that would pay the national or regional government at least $10 per ton of reduced carbon dioxide.

Companies will not be allowed to participate unless they have a scientifically sound plan to reach net zero emissions, according to Nigel Purvis, the chief executive of Climate Advisers, a group affiliated with the initiative. “Their number one obligation to the world from a climate standpoint is to reduce their own emissions across their supply chains, across their products, everything,” Mr. Purvis said. He also emphasized that the coalition’s plans would respect the rights of Indigenous and forest communities.

I Used to Fear Being a Nobody. Then I Left

Social Media.

By Bianca Brooks

“What’s happening?”

I stare blankly at the little box as I try to think of something clever for my first tweet. I settle on what’s at the top of my mind: “My only #fear is being a nobody.” How could I know this exchange would begin a dialogue that would continue nearly every day for the next nine years of my life?

I began using Twitter in 2010 as a newly minted high school freshman. Though it began as a hub for my quirky adolescent thoughts, over the years it became an archive of my emotional and intellectual voice — a kind of virtual display for the evolution of my politics and artistic identity. Butafter nine years, it was time to close the archive. My wanting to share my every waking thought became eclipsed by a desire for an increasingly rare commodity — a private life.

Though I thought disappearing from social media would be as simple as logging off, my refusal to post anything caused a bit of a stir among my small but loyal following. I began to receive emails from strangers asking me where I had gone and when I would return. One message read: “Not to be over familiar, but you have to come back eventually. You’re a writer after all. How will we read your writing?” Another follower inquired, “Where will you go?”

The truth is I have not gone anywhere. I am, in fact, more present than ever

Over time, I have begun to sense these messages reveal more than a lack of respect for privacy. I realize that to many millennials, a life without a social media presence is not simply a private life; it is no life at all: We possess a widespread, genuine fear of obscurity.

When I consider the near-decade I have spent on social media, this worry makes sense. As with many in my generation, Twitter was my entry into conversations happening on a global scale; long before my byline graced any publication, tweeting was how I felt a part of the world. Twitter functions much like an echo chamber dependent on likes and retweets, and gaining notoriety is as easy as finding someone to agree with you. For years I poured my opinions, musings and outrage onto my timeline, believing I held an indispensable place in a vital sociopolitical experiment.

But these passionate, public observations were born of more than just a desire to speak my mind — I was measuring my individual worth in constant visibility. Implicit in my follower’s question “Where will you go?” is the resounding question “How will we know where you’ve gone?” Privacy is considered a small exchange for the security of being well known and well liked.

After all, a private life boasts no location markers or story updates. The idea that the happenings of our lives would be constrained to our immediate families, friends and real-life communities is akin to social death in a world measured by followers, views, likes and shares.

I grow weary when I think of this as the new normal for what is considered to be a fruitful personal life. Social media is no longer a mere public extension of our private socialization; it has become a replacement for it. What happens to our humanity when we relegate our real lives to props for the performance of our virtual ones?

For one, a predominantly online existence can lull us into a dubious sense of having enacted concrete change, simply because of a tweet or Instagram post. As “hashtag activism” has obscured longstanding traditions of assembly and protest, there’s concern that a failure to transition from the keyboard to in-person organization will effectively stall or kill the momentum of political movements. (See: Occupy Wall Street.)

The sanctity of our most intimate experiences is also diminished. My grandfather Charles Shaw — a notable musician whose wisdoms and jazz scene tales I often shared on Twitter — passed away last year. Rather than take adequate time to privately mourn the loss of his giant influence in my life alongside those who loved him most, I quickly posted a lengthy tribute to him to my followers. At the time I thought, “How will they remember him if I don’t acknowledge his passing?”

Perhaps at the root of this anxiety over being forgotten is an urgent question of how one ought to form a legacy; with the rise of automation, a widening wealth gap and an unstable political climate, it is easy to feel unimportant. It is almost as if the world is too big and we are much too small to excel in it in any meaningful way. We feel we need as many people as possible to witness our lives, so as not to be left out of a story that is being written too fast by people much more significant than ourselves.

“The secret of a full life is to live and relate to others as if they might not be there tomorrow, as if you might not be there tomorrow,” the writer Anais Nin said. “This feeling has become a rarity, and rarer every day now that we have reached a hastier and more superficial rhythm, now that we believe we are in touch with a greater amount of people. This is the illusion which might cheat us of being in touch deeply with the one breathing next to us.”

I think of those words and at once any fear of obscurity is eclipsed by much deeper ones — the fear of forgoing the sacred moments of life, of never learning to be completely alone, of not bearing witness to the incredible lives of those who surround me.

I observe the world around me. It is big and moving fast. “What’s happening?” I think to myself.

I’m just beginning to find out.

Can you learn in your sleep?

Sleep is known to be crucial for learning and memory formation. What's more, scientists have even managed to pick out specific memories and consolidate them during sleep. However, the exact mechanisms behind this were unknown — until now.

Those among us who grew up with the popular cartoon "Dexter's Laboratory" might remember the famous episode wherein Dexter's trying to learn French overnight. He creates a device that helps him to learn in his sleep by playing French phrases to him. Of course, since the show is a comedy, Dexter's record gets stuck on the phrase "Omelette du fromage" and the next day he's incapable of saying anything else. This is, of course, a problem that puts him through a series of hilarious situations.

The idea that we can learn in our sleep has captivated the minds of artists and scientists alike; the possibility that one day we could all drastically improve our productivity by learning in our sleep is very appealing. But could such a scenario ever become a reality?

New research seems to suggest so, and scientists in general are moving closer to understanding precisely what goes on in the brain when we sleep and how the restful state affects learning and memory formation.

For instance, previous studies have shown that non-rapid eye movement (non-REM) sleep — or dreamless sleep — is crucial for consolidating memories. It has also been shown that sleep spindles, or sudden spikes in oscillatory brain activity that canbe seen on an electroencephalogram (EEG) during the second stage of non-REM sleep, are key for this memory consolidation. Scientists were also able to specifically target certain memories and reactivate, or strengthen, them by using auditory cues.

However, the mechanism behind such achievements remained mysterious until now. Researchers were also unaware if such mechanisms would help with memorizing new information.

Therefore, a team of researchers set out to investigate. Scott Cairney, from the University of York in the United Kingdom, co-led the research with Bernhard Staresina, who works at the University of Birmingham, also in the U.K. Their findings were published in the journal Current Biology.

Cairney explains the motivation for the research, saying, "We are quite certain that memories are reactivated in the brain during sleep, but we don't know the neural processes that underpin this phenomenon." "Sleep spindles," he continues, "have been linked to the benefits of sleep for memory in previous research, so we wanted to investigate whether these brain waves mediate reactivation. If they support memory reactivation, we further reasoned that it could be possible to decipher memory signals at the time that these spindles took place."

To test their hypotheses, Cairney and his colleagues asked 46 participants "to learn associations between words and pictures of objects or scenes before a nap." Afterward, some of the participants took a 90-minute nap, whereas others stayed awake. To those who napped, "Half of the words were [...] replayed during the nap to trigger the reactivation of the newly learned picture memories," explains Cairney.

"When the participants woke after a good period of sleep," he says, "we presented them again with the words and asked them to recall the object and scene pictures. We found that their memory was better for the pictures that were connected to the words that were presented in sleep, compared to those words that weren't," Cairney reports.

Using an EEG machine, the researchers were also able to see that playing the associated words to reactivate memories triggered sleep spindles in the participants' brains. More specifically, the EEG sleep spindle patterns "told" the researchers whether the participants were processing memories related to objects or memories related to scenes.

"Our data suggest that spindles facilitate processing of relevant memory features during sleep and that this process boosts memory consolidation," says Staresina. "While it has been shown previously," he continues, "that targeted memory reactivation can boost memory consolidation during sleep, we now show that sleep spindles might represent the key underlying mechanism."

Cairney adds, "When you are awake you learn new things, but when you are asleep you refine them, making it easier to retrieve them and apply them correctly when you need them the most. This is important for how we learn but also for how we might help retain healthy brain functions."

Staresina suggests that this newly gained knowledge could lead to effective strategies for boosting memory while sleeping.

So, though learning things from scratch à la "Dexter's Lab" may take a while to become a reality, we can safely say that our brains continue to learn while we sleep, and that researchers just got a lot closer to understanding why this happens.

How a Canadian Chain Is Reinventing Book Selling

By Alexandra Alter

About a decade ago, Heather Reisman, the chief executive of Canada’s largest bookstore chain, was having tea with the novelist Margaret Atwood when Ms. Atwood inadvertently gave her an idea for a new product. Ms. Atwood announced that she planned to go home, put on a pair of cozy socks and curl up with a book. Ms. Reisman thought about how appealing that sounded. Not long after, her company, Indigo, developed its own brand of plush “reading socks.” They quickly became one of Indigo’s signature gift items.

“Last year, all my friends got reading socks,” said Arianna Huffington, the HuffPost cofounder and a friend of Ms. Reisman’s, who also gave the socks as gifts to employees at her organization Thrive. “Most people don’t have reading socks — not like Heather’s reading socks.”

Over the last few years, Indigo has designed dozens of other products, including beach mats, scented candles, inspirational wall art, Mason jars, crystal pillars, bento lunchboxes, herb growing kits, copper cheese knife sets, stemless champagne flutes, throw pillows and scarves.

It may seem strange for a bookstore chain to be developing and selling artisanal soup bowls and organic cotton baby onesies. But Indigo’s approach seems not only novel but crucial to its success and longevity. The superstore concept, with hulking retail spaces stocking 100,000 titles, has become increasingly hard to sustain in the era of online retail, when it’s impossible to match Amazon’s vast selection.

Indigo is experimenting with a new model, positioning itself as a “cultural department store” where customers who wander in to browse through books often end up lingering as they impulsively shop for cashmere slippers and crystal facial rollers, or a knife set to go with a new Paleo cookbook. Over the past few years, Ms. Reisman has reinvented Indigo as a Goop-like, curated lifestyle brand, with sections devoted to food, health and wellness, and home décor.

Ms. Reisman is now importing Indigo’s approach to the United States. Last year, Indigo opened its first American outpost, at a luxury mall in Millburn, N.J., and she eventually plans to open a cluster of Indigos in the Northeast. Indigo’s ascendance is all the more notable given the challenges that big bookstore chains have faced in the United States. Borders, which once had more than 650 locations, filed for bankruptcy in 2011. Barnes & Noble now operates 627 stores, down from 720 in 2010, and the company put itself up for sale last year. Lately, it has been opening smaller stores, including an 8,300-square-foot outlet in Fairfax County, Va.

“Cross-merchandising is Retail 101, and it’s hard to do in a typical bookstore,” said Peter Hildick-Smith, president of the Codex Group, which analyzes the book industry. “Indigo found a way to create an extra aura around the bookbuying experience, by creating a physical extension of what you’re reading about.”

The atmosphere is unabashedly intimate, cozy and feminine — an aesthetic choice that also makes commercial sense, given that women account for some 60 percent of book buyers. A section called “The Joy of the Table” stocks Indigobrand ceramics, glassware and acacia wood serving platters with the cookbooks. The home décor section has pillows and throws, woven baskets, vases and scented candles. There’s a subsection called “In Her Words,” which features idea-driven books and memoirs by women. An area labeled “A Room of Her Own” looks like a lushdressing room, with vegan leather purses, soft gray shawls, a velvet chair, scarves and journals alongside art, design and fashion books.

Books still account for just over 50 percent of Indigo’s sales and remain the central draw; the New Jersey store stocks around 55,000 titles. But they also serve another purpose: providing a window into consumers’ interests, hobbies, desires and anxieties, which makes it easier to develop and sell related products.

Publishing executives, who have watched with growing alarm as Barnes & Noble has struggled, have responded enthusiastically to Ms. Reisman’s strategy. “Heather pioneered and perfected the art of integrating books and nonbook products,” Markus Dohle, the chief executive of Penguin Random House, said in an email.

Ms. Reisman has made herself and her own tastes and interests central to the brand. The front of the New Jersey store features a section labeled “Heather’s Picks,” with a display table covered with dozens of titles. A sign identifies her as the chain’s “founder, C.E.O., Chief Booklover and the Heather in Heather’s Picks.” She appears regularly at author signings and store events, and has interviewed prominent authors like Malcolm Gladwell, James Comey, Sally Field, Bill Clinton and Nora Ephron.

When Ms. Reisman opened the first Indigo store in Burlington, Ontario, in 1997, she had already run her own consulting firm and later served as president of a soft drink and beverage company, Cott. Still, bookselling is an idiosyncratic industry, and many questioned whether Indigo could compete with Canada’s biggest bookseller, Chapters. Skepticism dissolved a few years later when Indigo merged with Chapters, inheriting its fleet of national stores. The company now has more than 200 outlets across Canada, including 89 “superstores.” Indigo opened its first revamped concept store in 2016.

The new approach has proved lucrative: In its 2017 fiscal year, the company’s revenue exceeded $1 billion Canadian for the first time. In its 2018 fiscal year, Indigo reported a revenue increase of nearly $60 million Canadian over the previous year, making it the most profitable year in the chain’s history.

The company’s dominance in Canada doesn’t guarantee it will thrive in the United States, where it has to compete not only with Amazon and Barnes & Noble, but with a resurgent wave of independent booksellers. After years of decline, independent stores have rebounded, with some 2,470 locations, up from 1,651 a decade ago, according to the American Booksellers Association. And Amazon has expanded into the physical retail market, with around 20 bookstores across the United States.

Ms. Reisman acknowledges that the company faces challenges as it expands southward. Still, she’s optimistic, and is already scouting locations for a second store near New York.
