A lot more goes into creating a book than just writing. Book designers work relentlessly perusing a variety of typography palettes and experimenting with different typesetting formats to make the book appeal just right. All of this is done not only to set the perfect mood for the reading experience but also to balance the toll that the aesthetics of the book might take on the enviornment.

HarperCollins Publishers, one of the leading publishing houses in the industry has ventured on a mission to save trees. Their design team conducted extensive research to curate a collection of eco-friendly fonts that use less ink, improving opacity and readability. With thoughtful layouts and design tweaks to conserve paper usage, their eco-friendly font project has saved more than 200 million pages so far, which is equivalent to preserving 5,618 trees.
This project started when HarperCollins’ Christian Publishing developed NIV Comfort Print® typeface in 2017. Changing to a compact typeface helped the company save over 100 million pages. If stacked up, these pages would be four times the height of the Empire State Building. This Christian publishing division is called “Zondervan Bibles,” according to FastCompany.
Tracey Menzies, the VP of creative operations and production at HarperCollins wanted to see if they could extend these fonts to other kinds of books apart from Bibles, including novels and nonfiction. “When we first started thinking about this, it was a bit of an upheaval,” she says. “You’re taking something that people have done for their entire careers and telling them to think about it in an entirely new way.”

The team started testing different fonts on the books with more than 600 pages in their catalog. They created fifty different versions by using different fonts. In the end, they curated a list of 15 fonts they found the most compact and, therefore, eco-friendly. The usage of these fonts, with slight tweaks in the layouts could save a lot of white space. For instance, the same text set to Garamond Pro resulted in many more words on the page compared to Bembo. “The goal is to make these changes without the reader even seeing the difference,” says Menzies.
But the goal of saving trees didn’t have to be on the cost of compromising on the reading appeal. The readability still had to be neat and clear. Whether it is plain-old serif font “Centaur” for a novel, or the lunchbox-nostalgia style “Schoolbell” required for a comic storybook. “It was simply a different approach that didn’t sacrifice aesthetics. Now, our designers are constantly questioning how we do things and thinking about ways to make things more sustainable,” says Menzies.

“Ultimately, this ended up with finding fonts that used less ink, in addition to less paper, which is also better for the planet,” said Leah Carlson-Stanisic, associate director of design at HarperCollins. This is not the first time HarperCollins has shown its utmost awareness and responsibility toward sustainability. In June 2023, according to PRNewswire, HarperCollins Publishers India partnered with Vedanta Ltd. to launch a nationwide plantation drive, “Plant a Tree; Grow a Future” on the occasion of World Environment Day.
Through this initiative, they planted 10,000 saplings in school premises, taking a pledge for a greener Earth. Ananth Padmanabhan, Chief Executive Officer at HarperCollins Publishers India, said, “Trees are an investment for future generations, providing cleaner air and natural shade. At HarperCollins, we promote sustainability through various practices and initiatives, be it the paper we use or the drives we organize.”

But it wasn’t until the 1960s that methodical research into dolphin communication began. Scientists like John Lilly and the husband-and-wife team of Melba and David Caldwell tried various experiments to decipher the sounds dolphins can make.
The Caldwells figured out a way to record isolated animals in human care. They discovered that each individual dolphin communicated mostly with one unique whistle, which they called the “signature whistle.” Researchers now know that these whistles convey identities much like human names do. Dolphins use them to stay in touch with each other in their murky habitat, where vision is limited. It’s like announcing “I’m over here!” when someone can’t see you.
This collaborative study, led by Randall Wells of Brookfield Zoo Chicago’s Sarasota Dolphin Research Program, involves numerous researchers from a variety of institutions, who study different aspects of dolphin biology, health, ecology and behavior. Begun in 1970, this is the longest-running research project on a population of wild cetaceans – whales, dolphins and porpoises – in the world.

Recording and observing
Researchers know the age, sex and maternal relatedness of almost all of the approximately 170 dolphins in the Sarasota community. This depth of knowledge provides an unprecedented opportunity to study communication in a wild cetacean species.
The dolphins in the Sarasota project are periodically subject to brief catch-and-release health assessments, during which researchers, including me, briefly handle individual dolphins.
Our team attaches suction-cup hydrophones directly onto each dolphin’s melon – that is, its forehead. We then record the dolphins continuously throughout the health assessments, taking notes on who is being recorded when, and what is happening at the time.
This is how my colleagues and I were able to confirm that wild dolphins, like captive animals, produced large numbers of individually distinctive signature whistles when briefly isolated from other dolphins. Through observations and recordings of known free-swimming dolphins, we were further able to confirm that they produced these same signature whistles in undisturbed contexts.
We have organized these recordings into the Sarasota Dolphin Whistle Database, which now contains nearly 1,000 recording sessions of 324 individual dolphins. More than half of the dolphins in the database have been recorded more than once.
We identify each dolphin’s signature whistle based on its prevalence: In the catch-and-release context, about 85% of the whistles that dolphins produced are signature whistles. We can identify these visually, by viewing plots of frequency vs. time called spectrograms.

Signature whistles and ‘motherese’
The Sarasota Dolphin Whistle Database has proved to be a rich resource for understanding dolphin communication. For instance, we have discovered that some calves develop signature whistles similar to those of their mothers, but many do not, raising questions about what factors influence signature whistle development.
Dolphin mothers modify their signature whistles when communicating with their calves by increasing the maximum frequency, or pitch. This is similar to human caregivers using a higher-pitched voice when communicating with young children – a phenomenon known as “motherese.”
Also similar to humans is how dolphins will initiate contact with another dolphin by imitating their signature whistle – what we call a signature whistle copy. This is similar to how you would use someone’s name to call out to them.
Our team is interested in finding out if dolphins also copy whistles of others who aren’t present, potentially talking about them. We have seen evidence of this in our recordings of dolphins during health assessments, which provide a rare context to document this phenomenon convincingly. But we still have more work to do to confirm that these are more than chance similarities in whistles.
Shared whistle types
Another exciting development has been our recent discovery of shared whistle types — ones that are used by multiple animals and that are not signature whistles. We call these non-signature whistles.
I could hardly believe my ears when I first discovered a repeated, shared non-signature whistle type being produced by multiple dolphins in response to sounds we play back to them through an underwater speaker. We had previously believed that these non-signature whistles were somewhat random, but now I was hearing many different dolphins making a similar whistle type.
Our team originally had been using the playbacks to try to determine whether dolphins use “voice cues” to recognize each other – similar to how you can recognize the voice of someone you know. Although we found that dolphins did not use voice cues, our discovery of shared non-signature whistle types has led to an entirely new research direction.

So far, I’ve identified at least 20 different shared non-signature whistle types, and I am continuing to build our catalog. We are hoping that artificial intelligence methods may help us categorize these whistle types in the future.
To understand how these shared non-signature whistle types function, we are carrying out more playback experiments, filming the dolphins’ responses with drones. We’ve found that one such whistle often leads the dolphins to swim away, suggesting a possible alarm-type function. We have also found that another type might be an expression of surprise, as we have seen animals produce it when they hear unexpected stimuli.
More difficult, more interesting
So far, the main takeaway from our experiments has been that dolphin communication is complex and that there are not going to be one-size-fits-all responses to any non-signature whistle type. This isn’t surprising, given that, like us, these animals have complicated social relationships that could affect how they respond to different sound types.
For instance, when you hear someone call your name, you may respond differently if you are with a group of people or alone, or if you recently had an argument with someone, or if you’re hungry and on your way to eat.
Our team has a lot more work ahead to sample as many dolphins in as many contexts as possible, such as different ages, sexes, group compositions and activities.
This makes my job more difficult – and far more interesting. I feel lucky every day I am able to spend working on the seemingly infinite number of fascinating research questions about dolphin communication that await answers.
Gavin, with help from aquarium staff, had secretly planned to propose right in front of the beluga whale tank. As he got down on one knee, a whale named Qinu swam into view.
The 16-year-old marine mammal paused right at the glass and appeared to drop her jaw in shock.
I’ve been interning with the beluga training team for the last 3 months so this was the most thoughtful way he could’ve done it 🥺 #georgiaaquarium#belugawhale#proposal
The moment was caught on video, and when Olivia shared it on TikTok, the comment section exploded. It looked exactly like the whale was gasping at the size of the ring.
“The most perfect proposal I could’ve asked for,” Olivia wrote.
Viewers immediately anthropomorphized the whale’s hilarious expression.
“The beluga NEEDS to officiate the wedding now,” one user joked.
Another simply commented: “The beluga: :O”
Even the official Play-Doh account chimed in to insist that the whale deserved a wedding invite.
According to People, Qinu’s involvement wasn’t a planned stunt. Katie Lorenz, the associate curator of mammals and birds at the Georgia Aquarium, confirmed that the reaction was entirely natural.
“Qinu’s behavior at the window was her own,” Lorenz said. “She was not intentionally trained to have any type of reaction.”
Unlike many other whales, belugas have unique physical characteristics that allow for this kind of “human” expression. They have a flexible neck and unfused cervical vertebrae, which allows them to nod and turn their heads.
Furthermore, their “melon” (the rounded forehead) is flexible and capable of changing shape, which often makes them appear to be smiling or making faces.
The moment was even more poignant because Olivia wasn’t just a random visitor. She had actually been a beluga whale training intern at the aquarium for the past three months.
“My fiancé is the most thoughtful person,” she wrote in a reply. “He knows how much I’ve loved working with the whales and truly made it the most special moment.”
The Conversation
Of course, viral videos involving captive animals often spark debate. Some commenters questioned the ethics of keeping an animal like Qinu in a tank.
“Nothing cute or adorable about these sentient creatures being kept confined in glass houses for human amusement,” one user wrote.

However, for the vast majority of viewers, the video was a moment of pure joy. The clip has racked up over 7 million views on TikTok alone, and Qinu has officially become the internet’s favorite wedding crasher.
For those who want to see more of the star, the Georgia Aquarium maintains a live beluga cam where fans can check in on Qinu. As for the happy couple, they now have a proposal story that is going to be very hard to top.

During mating season, male gentoo penguins are tasked to find pretty and smooth rocks to present to prospective mates. This is meant as a gesture to woo them and to be used to build a nest with them, too. Well, this season, the penguins at the Edinburgh Zoo in Scotland got some help.
Kids being supported by the Edinburgh Children’s Hospital Charity gathered together to paint pebbles with vibrant colors for the penguins. The hospitalized children do this every year with the first stone traditionally placed in the penguin enclosure. The children often watch a livestream of the gentoo penguin enclosure to see the penguin pick their favorite rocks that they’ve painted.
The Edinburgh Zoo posted this year’s pebbling pickings on Instagram, delighting the commenters:
“I would cry if a penguin picked MY pebble 😭 It’s a life goal lol.”
“This is just brilliant! How wonderful to see a creative health initiative that actively connects the children with a purpose like this!”
“This is heartwarming ❤️❤️❤️”
“This is brilliant for the penguins and the children! Can’t wait to see the beautiful nests.”
“My grandson painted a pebble he’s hoping it gets picked.🤞🤞🤞”
“Penguin pebble pilfering season is upon us! So pleased it makes so many people (and penguins) happy.”
“Oh no, now I’m questioning if penguins have favourite colours.”
“Any that aren’t picked would make an awesome rock garden that kids visiting the zoo could pick from!!”
“This is the cutest thing I have seen probably ever.”
Pebbling practices for human relationships
As mentioned, this mating ritual called “pebbling” is a gesture made by male penguins to their mate to not just build a nest. It’s their version of saying, “I saw this and I thought of you.” In fact, psychologists and couples therapists recommend adopting a version of pebbling for human relationships.
Now to “pebble” in dating or married relationships doesn’t literally mean giving your partner rocks (unless they’re a geologist that would love that sort of thing). For humans, pebbling your partner means to share or give a small gift like a flower, toy, or object that has some meaning to one or both of you. It doesn’t always have to be a gift either, but it could be a photo, social media post, or a meme you can text them. It’s essentially anything that conveys “I saw this and thought of you” in order to showcase affection to them and initiate closer conversations.
Pebbling isn’t just for romantic couples either. Many autistic people find it more difficult to navigate socially due to high anxiety, sensory sensitivities, or having trouble interpreting social cues. By texting a GIF to a friend, giving a small flower to their parent during a walk, or other such pebbling, it allows some autistic people the ability to communicate their affection and connection without the pressure of using words.
Whether it’s a colorful rock or something else, pebbling can be a valid form of communication between friends, partners, or potential mates. It all depends on who you choose to build a nest with.
