Nature offers some of the most extraordinary and breathtaking scenes to those who dare to explore. The National Geographic series Secrets of the Octopus captures stunning visuals of a marine biologist interacting with these fascinating creatures, reports Newsweek. Shot in the Great Barrier Reef and other locations, the series dives into the hidden lives and behaviors of octopuses, revealing their mysterious habits and lifestyles.

The series trailer, shared by National Geographic, reveals the octopus in all its majesty and highlights the vast potential for study. Dubbed “shapeshifters” and “aliens,” the octopus is shown to have more in common with humans than we might think. Marine biologist Alex Schnell, who explores their world in the series, describes her “magical experience,” saying, “They’re as curious about you as you are about them.”

Talking to Newsweek, Schnell said, “Cephalopods [the animal group that contains octopuses, squid and related creatures] were always a point of interest from a very young age.” Pointing out to their “alien” factor, she said, “They’re just so alien—they have three hearts that pump blue blood, no bones, and skin that can change color in an eye-blink. But within this really strange framework, we’re seeing glimmers of intelligence that we might normally expect to see in, say, dolphin chimpanzees or elephants.” Right from observing the octopuses to engaging with them, the series has captured a plethora of footage with priceless knowledge to extract. The crew filmed for around 1500 hours in different locations to get a natural and first-hand understanding of what these sea creatures have to offer.

Schnell interacted with the octopuses of various kinds in their habitats in unique ways. The need to capture authentic footage required her to bond with the octopuses which resulted in an invaluable experience. Of all the amazing footage captured throughout the filming process, the crew was particularly amazed by an octopus in the Great Barrier Reef, who the team interestingly named “Scarlett.” They even captured an instance where a fish did a sort of “headstand” to communicate with the octopus. “We were able to see rare footage of interspecies communication and collaborative hunting, with the octopus understanding that this coral trout was doing a headstand to indicate where a crab was hiding,” Schnell said.

She added that since the fish don’t have hands, the headstand was a way of communicating or gesturing about the prey hidden.  As a form of “crazy” research, Schnell tried to gesture the octopus similarly and the result did not disappoint. “She let me get super close and I could see that as she was putting her arms underneath the coral rubble crabs would swim out and escape her grasp. So I just randomly started to point to where these crabs would go and she immediately responded,” Schnell said. “This is just the first step, but it would be a really interesting avenue to further investigate,” she exclaimed.

    Scottish children are helping penguins find mating partners with these tiny, painted stones

    “I would cry if a penguin picked MY pebble 😭 It’s a life goal”

    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.

    Commenters sound off on the penguins’ pebbling

    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.

  • Scientists have created a leather clothing alternative made entirely from mushrooms that looks and feels like the real thing

    Austria’s scientists have created a leather made from mycelium. Growing mushrooms in low-oxygen chambers allows researchers to craft an alternative material that feels and looks like traditional leather. The finished textile is strong, flexible, and even fire-resistant.

    Manufacturers grow the material instead of harvesting it from animals. After it reaches the desired thickness, they apply non-toxic enzymes to keep it fully biodegradable. The vegetative part of the fungus grows into a dense mat over a matter of days. Above all, it avoids the environmental impact of traditional leather production.

    Alternative leather made from mushrooms

    This is not science fiction; fungal fabric has grown from a curiosity into reality. A 2025 report listed the benefits of mushroom leather as having a lower carbon footprint. It begins with a substantial reduction in water use. Growing mushrooms, compared to raising cattle, requires a fraction of the water.

    Secondly, the product breaks down naturally without microplastic contamination. Using enzymes that cross-link the fibers results in a material free of blended toxic materials.

    Moreover, by creating the right environment—a low-oxygen chamber with a nutrient-rich substrate—the mushroom mat can be grown in a matter of days.

    Lastly, mushroom leather is naturally fire-resistant. There’s no need for harmful chemicals to treat the textile. In addition, clean up requires mild soap and lukewarm water.

    A 2026 study in ScienceDirect confirmed the fungal mycelium as an eco-friendly alternative to traditional and synthetic leathers. It demonstrates structural integrity and favorable thermal stability.

    Is the public ready for vegan leather?

    People have conflicting thoughts, as seen in the comments on the Instagram post. Some individuals are excited and encouraged by the possibilities. Others, however, are less impressed:

    “I’m ready for it. How do we buy it?”

    “Make it affordable and common!”

    “As long as the final product keeps being painted and coated with chemicals, the purpose of the product is merely green washing.”

    “bio degradable? sorry your shoes were eaten by mold after the rain.”

    “Where we can buy this leather?”

    “Unless we’re talking about aprons/gloves for welders or blacksmiths (which is a fairly niche market), flammability isn’t something most people that wear leather are concerned about.”

    Fashion looks for sustainable, yet affordable materials

    Fashion leaders are looking to incorporate more sustainable fabrics into their creations. A 2025 post on Open Forem explored material choices for leading industry fashion designers in 2025. For example, more familiar textiles like polyester, organic cotton, and wool made their traditional rounds. But there was an effort to use plant-based leathers, too.

    Mushroom mycelium leather was a hot choice for its low environmental impact, its short creation time, and its customizable texture and thickness.

    Other exotic materials included banana fibers, seaweed-based fabrics, and Piñatex, a natural, low-impact textile made from pineapple leaf fibre. Designers fashion the plant-based material into vegan handbags, shoes, and wallets.

    A 2026 article in Vogue revealed that Gucci seeks more sustainable ways to produce leather products. The luxury brand began a campaign for vegan alternative leather back in 2021.

    Despite commercial adoption remaining somewhat limited, mushroom leather continues to attract attention for its eco-friendly production and versatility. Grown on agricultural waste while remaining fully biodegradable are cornerstones of this remarkable material.

  • Scientists create environmentally friendly plastic replacement from shrimp shells

    Plastic waste has been a growing global issue for years. The United Nations Environment Programme says that 19 to 23 million metric tonnes of plastic waste leaks into lakes, rivers, and oceans each year. Given the threat microplastics pose to animal and human health, efforts to find green replacements have intensified—and they’re working. Scientists from Singapore and Spain have found a strong, potentially viable replacement for plastic made from shrimp shells.

    A research team based at the Singapore University of Technology and Design and the Institute for Bioengineering of Catalonia in Barcelona has made a biodegradable plastic alternative out of chitosan. Chitosan is a compound created by combining shrimp shells with trace amounts of nickel. It contains a structural molecule found in the shells of crustaceans and insect exoskeletons. Usually discarded as a waste byproduct of shrimp and crab processing, chitosan is commonly produced during seafood preparation and commercial fishing.

    The issue with chitosan, though, was that it weakens and dissolves in water. That is, until recently.

    How chitosan got stronger

    Dissolving chitosan flakes into a weak acetic solution and mixing them with dissolved nickel chloride and water produced surprising results. Scientists then poured the mixture into molds to dry. The process yields a thin, green-tinted film with the strength of commonly used plastics like polypropylene. Even better, when submerged in water, the film grows 50% stronger. This increased durability matches the characteristics of polycarbonate and PETG, plastics commonly used in commercial single-use water bottles.

    Researchers then stress-tested the chitosan material by molding it into cups and containers. They were able to confirm it could hold water without leaks. In terms of biodegradability, the chitosan material reached its half-life in four months in a standard soil burial test. By contrast, most commercial plastics can take centuries to decompose under similar conditions.

    Researchers found that this is not only a better biodegradable plastic alternative, but also one that produces zero waste during creation. When the chitosan/nickel film is submerged, about 87% of the nickel washes out. That wash water can then be reused again and again from one batch of chitosan to the next. According to the researchers, the nickel content of a single AAA battery would provide enough nickel to manufacture more than a dozen chitosan drinking cups.

    The potential future

    Rigorous testing to assess the material’s limits for medical use and consumption still needs to be done. That said, the Food and Drug Administration has already approved products containing chitosan and nickel individually in the past. Barring any troubling research about their combined safety, the outlook is quite positive for future use.

    Hopefully, seafood and battery waste can be reduced, helping lower plastic waste in a three-way win for the environment.
