You already know that pineapples are delicious and super rich in Vitamin C, but did you know that they could be transformed into a fabulous purse or great pair of running shoes?

It’s hardly a secret that eating a vegan diet is kinder to animals, and many experts believe that a plant-based diet can have life-changing effects on the health of an individual and even the world at large. With the number of vegans around the world on the rise, it’s not just the food industry that needs to adapt. The growing public demand for alternatives to leather and other animal products when it comes to clothing and textiles means that companies are coming up with all sorts of creative options. One London-based company, Ananas Anam, has devised a delicious solution to creating vegan materials: Pineapples.

Called Piñatex, the environmentally-friendly textile is created from the fibers of leftover pineapple leaves, which are extracted through a process known as "decortication." Since the leaves are a byproduct of the pineapple harvest, there is no need for extra water, land, fertilizers, or even pesticides to produce the material. It has a low environmental impact, can be easily mass produced and, perhaps most importantly, is affordable for consumers looking to give their wardrobes a socially-conscious makeover. As the pineapple leaves are harvested in the Philippines by local farmers, Ananas Anam’s products are also helping to create more jobs.

“The farming communities in the Philippines will benefit from the added income from the extraction of the fiber,” Jeanne Rideau, Ananas Anam’s public relations and communications manager tells mental_floss. “Moreover, the potential use of biomass, which is the byproduct of the fiber extraction, will give the farmers the opportunity of using natural fertilizers.”

Spanish designer, researcher, and entrepreneur Dr. Carmen Hijosa is the founder and chief executive officer of Ananas Anam. Hijosa’s first company was based in Ireland, where she designed and manufactured leather products for such companies as Harrods. Her work eventually brought her to the Philippines, where she saw a traditional Filipino shirt made out of pineapple leaves.

“As a designer, my objective was to create a product that carried social and ecological responsibility throughout its life cycle, and through it, do something about how to sustain and indeed to heal planet Earth through our actions,” Hijosa says. “Piñatex represents a sustainable solution in the face of today’s social and sustainable dilemmas.”

In an interview with, Hijosa explained that to create the final Piñatex material, the pineapple leaf fibers are made into a mesh, which then goes through both "mechanical and chemical processes to make it into a very strong product" that can be used to create a variety of products, including clothing, shoes, purses, accessories, and even upholstery.

You are probably wondering where to get some cool pineapple shoes of your own. Well, the wait is over—at least in certain parts of the world. A selection of the company’s products are available for purchase in the UK, as well as online. And well-known brands including Puma and Camper have already made prototypes using Piñatex.

Perhaps the even bigger question everyone is wondering is: do Piñatex products actually smell like pineapples? “No, there is no smell,” Rideau says. Now you know.

Why Scientists Are Hunting Down Iguanas in Florida

In South Florida, iguanas had better watch their backs. That's because scientists are on an unusual hunt to kill them, with the help of captive bolt guns and a $63,000 research grant, according to the Sun Sentinel.

It's not as cruel as it might seem at first glance. The green iguana, native to Central and South America, is an invasive species in Florida. The large lizards—which can grow up to 6 feet long—first made it to Florida in the 1960s, and as their population has exploded, they have expanded farther north. The reptiles damage roads, sidewalks, sea walls, and flood-control canals with their burrows; chomp their way through landscaping; spread Salmonella, largely by pooping in people's backyard pools; and compete with the endangered Miami blue butterfly for precious food resources.

The population boom has caused an uptick in complaints from residents, Florida Fish and Wildlife's Sarah Funck told the Sun Sentinel in 2017, pushing the state to find new strategies to deal with the reptiles. One approach? Hire scientists to hunt them down and kill them.

As part of the Florida Fish and Wildlife research project, 15 University of Florida biologists have been tasked with executing as many iguanas as possible in Broward County (home to Fort Lauderdale and parts of the Miami metropolitan area), setting out in teams of two at night. Armed with flashlights and captive bolt guns—which are often used on animals in slaughterhouses and are considered a humane way of killing an animal instantly and painlessly—the researchers attempt to sneak up on sleeping lizards and shoot them before they can scurry away. They also sometimes dispatch the iguanas by smashing their heads against a hard surface, including the side of a truck or a boat.

They've exterminated 249 lizards so far. They take the dead animals back to the lab to be weighed and measured for their dataset, then deposit the carcasses in a landfill. The iguana killing spree is expected to last into May.

While they have tried trapping the iguanas in county parks, they haven't succeeded in capturing any with that method.

As part of the Fish and Wildlife Conservation Commission's iguana-eradicating efforts, the agency has also been hosting public workshops on how to deter and trap iguanas and has hired a dedicated trapper to control populations on public lands in the Florida Keys.

7 Technologies That Are Revolutionizing Ocean Exploration

The Earth is an ocean planet—more than 70 percent of the surface is covered by seawater. But despite being such an essential part of life, the deepest parts of the world's oceans are still largely unexplored. According to the American Museum of Natural History in New York, merely 10 to 15 percent of the seafloor has been mapped with accuracy, which means we know less about the seafloor than the surface of Mars.

But the state of sea exploration is changing fast. The dark, high-pressure conditions of the ocean depths that once made research there impossible are now being explored with cutting-edge technology. That new tech and the discoveries to come from it are the focus of a new exhibition at the American Museum of Natural History called Unseen Oceans. As museum curator John Sparks said at a press preview, the goal of the exhibition is to show visitors "how little we know, and to tell them how much we're learning so rapidly with technology."

Here are some of the technologies featured in the exhibition, which opens March 12.


One of the biggest recent discoveries made in the field of deep ocean exploration is the proliferation of biofluorescence in the darkest parts of the sea. Realms that look pitch black to human eyes are actually filled with more than 250 species of fish glowing in red, orange, and green hues. One of these species is the catshark, which fluoresces green in the dim blue light that reaches the sea floor. To detect this effect, researchers built a camera that filters out certain wavelengths of light like the shark's eye does. (This is how the sharks see each other in the darkness.) Combined with artificial blue light to enhance the fluorescent color, this equipment allows scientists to record the light show.


Listening to whales vocalize tells us a lot about the way they live and interact, but this is difficult to do when a species spends most of its time in the deep ocean. In order to eavesdrop on beaked whales, scientists needed to fit sophisticated acoustic equipment into a submersible built to explore high-pressure environments. Enter the Deep Ocean REMUS Echosounder, or DOR-E. (REMUS stands for "Remote Environmental Monitoring UnitS.") Developed by marine scientist Kelly Benoit-Bird and her team at the Monterey Bay Aquarium Research Institute, the autonomous underwater vehicle can reach depths up to 1970 feet and has enough battery life to record a day's worth of deep-sea audio. The device was named for Finding Nemo's Dory because it "speaks whale," according to Unseen Oceans.

Collecting specimens at the bottom of the ocean isn't as simple as collecting them on land; researchers can't just step out of their submersible to pick up a mollusk from the seabed. The only way to retrieve a sample at such depths is with a machine. When these machines are designed to be bulky and rigid to withstand the intense water pressure around them, they can end up crushing the specimen before scientists have the chance to study it. So-called soft grippers are a clever alternative. Memory foam evenly distributes the force around the creature being handled, and Kevlar lace keeps the fingers from spreading when they inflate with water. Even with its squishy construction, the mechanism is sturdy enough to work at depths reaching 1000 feet.


A remotely operated vehicle (ROV) can explore the tight, crushing pockets of the ocean that human divers can't reach. This technology is often costly and limited to research teams with big budgets. A new company called OpenROV aims to make underwater drones more accessible to everyday explorers. Their signature ROV, Trident, starts at just $1500.

Sometimes the easiest way for scientists to get a view of the bottom of the ocean is by sending equipment to space. Satellites in orbit can estimate measurements of the peaks and valleys shaping the seabed by beaming radar pulses towards Earth and calculating the time it takes for them to bounce back. While this method doesn't provide a terribly accurate map of the ocean floor, it can be used to gauge depths in even the most remote areas.


Autonomous undersea robots come in all shapes and sizes. Mini-autonomous underwater explorers, or m-AUEs, developed by Scripps oceanographer Jules Jaffe are meant to be deployed in large groups or "swarms." The grapefruit-sized devices act like plankton, bobbing at a constant depth in the ocean and measuring factors like water temperature. By studying the underwater explorers, scientists hope to better understand how plankton, major contributors of the Earth's oxygen, thrive and travel through the sea.

This technology is so new, it hasn't hit the water yet. Once it's ocean-ready, researchers plan to attach the miniature suction cups to the bells of jellies. The device automatically measures a jelly's movements and ocean chemistry as the animal swims around. Eventually the jelly regenerates the top layer of its bell, shedding the tag and moving on unharmed. Once detached, the tag floats to the water's surface where it alerts scientists to its location via a VHF antenna and green reflective tape.
